Family Law

This toolkit is the front door to family law on UpLaw. It maps the whole field — marriage and its legal incidents, cohabitation, premarital and marital agreements, divorce and dissolution, property division and valuation, spousal and child support, custody and the UCCJEA, parentage and assisted reproduction, adoption, and domestic violence protective orders — and then walks the intersections with estate planning, business ownership, intellectual property, and immigration. Family law is state law, so each pillar teaches the framework, the uniform act or constitutional rule that supplies the common architecture, and the representative state variations, with a standing instruction to confirm your own state's rule. A recurring worked example follows one fictional family, the Halloran-Nakashima household, whose matters span a prenup, a contested divorce, a custody move-away, and a rebuilt estate plan. Use it as a research map: skim the landscape, jump to the pillar you need, and follow the links into UpLaw's deeper guides and checklists.

Family law is where the most private facts of a life meet the bluntest instruments of the state: a decree, a support order, a parenting schedule, a protective order. It is also the most state-specific field in American practice — there is no federal family code. This toolkit is the map to the common architecture underneath the fifty variations.

Keywords: family law, marriage, cohabitation, prenuptial agreement, divorce, property division, community property, equitable distribution, spousal support, child support, custody, UCCJEA, parentage, adoption, protective orders, QDRO

How to read this toolkit

Family law is not one subject. It is ten, loosely stapled together by the fact that the same people keep appearing in all of them. A marriage creates a status; that status carries property, support, and inheritance consequences; children generate an entirely separate body of law that survives the marriage and often outlives the divorce; and violence inside the household triggers a fast, quasi-criminal remedy that sits on top of everything else. Each of these has its own doctrine, its own governing uniform act or constitutional rule, and its own classic mistakes.

This toolkit walks those ten pillars in the order a family tends to encounter them. It is a research map, not a treatise. Each pillar gives you the plain-English doctrine, the anchor authority, the traps that catch people, and a link into UpLaw's deeper guide or checklist where the real detail lives.

One warning before you start, and it governs every line below. Family law is state law. Congress has never enacted a family code, and the Supreme Court has recognized a "domestic relations exception" that keeps divorce, alimony, and custody decrees out of federal diversity jurisdiction (Ankenbrandt v. Richards, 504 U.S. 689 (1992)). What holds the field together is a thin federal-constitutional floor, a set of federal funding conditions that coerce uniformity on support, and a family of uniform acts — the Uniform Marriage and Divorce Act (UMDA), the Uniform Premarital and Marital Agreements Act (UPMAA), the Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA), the Uniform Interstate Family Support Act (UIFSA), and the Uniform Parentage Act (UPA). Learn the uniform-act architecture and the constitutional cases, then confirm the rule in your own state before you act. A statement that is true in Texas is frequently false in New York.

Two habits of mind will save you throughout. First, treat every "the rule is" sentence in this toolkit as a hypothesis about your state, not a holding. Where a uniform act supplies the architecture, states have amended it on enactment; where no uniform act governs — alimony formulas, relocation presumptions, surrogacy validity — the variation is total. Second, check the numbers, not just the doctrine. Residency periods, notice windows, rescission periods, and guideline formulas are all jurisdiction-specific integers, and getting one wrong is malpractice in a way that a slightly imprecise doctrinal statement usually is not.

A running example keeps it concrete. Meet the Halloran-Nakashima family, fictional residents of a hypothetical equitable-distribution state. Nora Halloran is a veterinary surgeon who owns 60% of a four-doctor practice. Ezra Nakashima is a documentary filmmaker with a back catalog that pays modest but real royalties. They signed a prenuptial agreement eleven days before their 2014 wedding. They have two children, Wren (9) and Kit (5). In 2026 the marriage ends, Nora is offered a hospital directorship in Denver, and both of their estate plans — drafted in 2015 and never touched since — turn out to be quietly catastrophic. By the end of this toolkit the Halloran-Nakashimas will have run through every pillar, and a closing section assembles their whole matter end to end with numbers.

For the doctrinal foundation beneath Pillars 3 through 6, keep Divorce: A Comprehensive Guide to Dissolution, Property Division, Support, and Custody open in the next tab.

Pillar 1 — Marriage, its legal incidents, and cohabitation

Marriage is a status, not merely a contract, and the state is a third party to it. Entering it requires capacity, consent, a license, and (in most states) solemnization; exiting it requires a judgment. What the status confers is a bundle of hundreds of default rules — a spousal elective share against the other's will, intestate inheritance, the marital and spousal testimonial privileges, health-care decision-making, Social Security derivative benefits, ERISA survivor annuities, the federal joint return, and the presumption of parentage over children born during the marriage.

The constitutional frame is short and famous. Loving v. Virginia, 388 U.S. 1 (1967), struck down anti-miscegenation laws and identified marriage as a fundamental right. United States v. Windsor, 570 U.S. 744 (2013), invalidated Section 3 of the Defense of Marriage Act. Obergefell v. Hodges, 576 U.S. 644 (2015), held that the Fourteenth Amendment requires states to license and recognize same-sex marriages — and, critically, held that same-sex couples are entitled to marriage "on the same terms and conditions" as opposite-sex couples, which is the hinge on which the parentage cases in Pillar 7 later turned. The Respect for Marriage Act, Pub. L. No. 117-228 (2022), added a statutory recognition backstop.

Common-law marriage survives in only a handful of jurisdictions, and the list has been shrinking for decades as states abolish it prospectively. Jurisdictions commonly identified as still permitting formation include Colorado, Iowa, Kansas, Montana, Oklahoma, Rhode Island, Texas, Utah, and the District of Columbia; New Hampshire recognizes such marriages only for probate purposes; and several states that abolished it still recognize marriages validly formed before the abolition date. Confirm the current status in the specific jurisdiction — this list changes, and some entries are contested even within their own courts. Where it exists, formation generally requires present agreement to be married, cohabitation, and holding out to the community — not merely living together for seven years, which is folklore, not law. If you are advising anyone who has ever lived in one of these places, ask the question, because a common-law marriage requires a divorce to end.

Cohabitation confers nothing by default. The leading case, Marvin v. Marvin, 18 Cal. 3d 660 (1976), held that unmarried partners may enforce express contracts and, in California, certain implied ones. But Marvin is a contract theory, not a status theory — it gives you whatever you actually agreed to, and nothing more. Other states rejected even that: Illinois refused to enforce such claims on public-policy grounds in Hewitt v. Hewitt (Ill. 1979), and reaffirmed that refusal decades later in Blumenthal v. Brewer (Ill. 2016). The practical answer for cohabiting partners is a written cohabitation agreement plus deliberate titling of the home, plus a will and powers of attorney, because none of the intestacy or health-care defaults will help them.

Trap. Clients routinely believe that long cohabitation creates rights. It does not, outside common-law-marriage states. The cost of that misunderstanding is usually a house titled in one name and twelve years of the other partner's mortgage payments with no restitution theory that survives summary judgment. For the titling side of that problem, see The Real Estate Transactions Toolkit.

Pillar 2 — Premarital and postnuptial agreements

A premarital agreement is how a couple contracts out of the property and support defaults before the status attaches. Roughly half the states follow the Uniform Premarital Agreement Act (1983); a smaller and growing group has adopted the Uniform Premarital and Marital Agreements Act (2012), which extends the same framework to agreements made during the marriage and tightens the procedural protections. A meaningful number of states follow neither and run on common law, so identify the governing regime before you analyze anything.

The analysis everywhere reduces to four questions:

  1. Formalities. Written and signed. Most states require no consideration beyond the marriage itself.
  2. Voluntariness. Was it signed under duress? Timing is the workhorse fact — an agreement produced on the eve of the wedding, with guests already flying in, is the classic setup for an involuntariness finding.
  3. Disclosure. Was there fair and reasonable disclosure of assets, income, and obligations — or a valid written waiver of disclosure?
  4. Substantive fairness. Was the agreement unconscionable when made (the UPAA standard) — and, in a minority of states, is it unconscionable at enforcement, judged against the life the parties actually lived?

Courts diverge sharply on how much paternalism to apply. Pennsylvania's Simeone v. Simeone (Pa. 1990) took a strongly contractarian line: a spouse who signs without reading is bound, and there is no separate judicial "reasonableness" review of the bargain. California moved the other way by statute after In re Marriage of Bonds, 24 Cal. 4th 1 (2000), with the legislature adding a seven-day review period and counsel-related requirements to its voluntariness test. Know which world you are in, because the same signing facts produce opposite outcomes in the two.

Two things a prenup cannot do anywhere: it cannot fix child support or custody in advance (those belong to the child, not the parents, and remain subject to the court's independent best-interests review), and it cannot contract away the court's power to modify child-related terms.

The Halloran-Nakashima prenup. Nora and Ezra signed eleven days before the wedding. Ezra had no separate counsel; his disclosure schedule listed "film royalties — approx. $30,000/yr" with no underlying statements. The agreement waived all spousal support and characterized each party's business as separate property, including its appreciation. In 2026 Ezra attacks it on voluntariness (timing, no counsel) and disclosure (Nora's practice interest was listed at book value, not appraised value). Whether he wins depends entirely on which state's statute governs — and this is exactly why the choice-of-law clause in the agreement is not boilerplate.

Pillar 3 — Divorce and dissolution

Every state now offers no-fault divorce, whether phrased as "irretrievable breakdown" (the UMDA formulation), "irreconcilable differences," or a mandatory separation period. Many states retain fault grounds as an alternative, and in some of those states fault still bleeds into alimony or property division even though it cannot bar the divorce itself. Others bar fault evidence from the financial analysis entirely. Ask whether your state is one of them before you decide that the affair is legally irrelevant — or that it is a windfall.

Jurisdiction is the first fight, not the last. Three separate jurisdictional questions hide inside one case:

Process and forum. Most divorces settle. The real choice is how: negotiation, mediation, collaborative law (see the Uniform Collaborative Law Act), a private judge or arbitrator where the state permits family arbitration, or a courtroom trial. Each trades speed and privacy against finality and appellate protection, and family cases add a wrinkle — child-related terms are never fully bargained away from judicial review, so a family "award" is less final than a commercial one. Work the tradeoff with Choosing a Dispute-Resolution Forum: Litigation, Arbitration, and Mediation Compared and, if the parties are contemplating a private adjudicator, Arbitration and ADR: A Toolkit for Choosing a Forum, Drafting Clauses, and Running a Case.

Financial discovery in a contested divorce is ordinary civil discovery pointed at a household: interrogatories, requests for production, subpoenas to banks and plan administrators, and depositions of the moneyed spouse and any valuation expert. State family rules govern, but the craft transfers directly from civil practice — see The Federal Discovery Toolkit: A Roadmap From Rule 26(f) to Sanctions for the mechanics of building and enforcing a document demand.

Trap. Automatic temporary restraining orders. Many states impose, on filing and service, standing injunctions freezing asset transfers, insurance changes, and beneficiary designations. Clients who "clean up" their finances after filing — retitling an account, cashing out a policy, changing a 401(k) beneficiary — commit contempt without knowing it. Read the summons; the injunction is often printed on the back of it.

Pillar 4 — Property division and valuation

Two regimes, one shared vocabulary.

Community property (Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin — plus Alaska's opt-in system) treats property acquired during marriage by either spouse as owned equally, with an equal or near-equal division at divorce. The individual states differ considerably in how they handle appreciation, reimbursement, and quasi-community property, so the label is the beginning of the analysis, not the end.

Equitable distribution (everywhere else) divides marital property equitably, which means fairly, not necessarily evenly, under a multi-factor statute drawn largely from UMDA § 307: length of the marriage, contributions including homemaking, economic circumstances, dissipation, and so on. A "hotchpot" minority allows a court to reach separate property; most states do not.

Whatever the regime, the sequence is the same and it is where cases are won:

  1. Identify every asset and liability, including the ones nobody put on the schedule.
  2. Characterize each as marital/community or separate. Separate property is generally what you brought in, plus gifts and inheritances received during the marriage, plus (usually) anything traceable to those.
  3. Trace. Commingling is the great destroyer of separate character. An inheritance deposited into a joint checking account and spent on groceries is gone as a separate asset in most states; the same inheritance kept in a segregated account and never touched survives. States differ on the tracing presumptions and on who carries the burden.
  4. Value. As of what date? Filing? Trial? A hybrid, or a date the court picks in its discretion? States differ, and in a volatile market the valuation date can be worth more than the argument about the percentage split.
  5. Divide, using offsets and, where necessary, a QDRO.

The hard assets. Retirement plans are usually the largest marital asset. Dividing an ERISA-governed plan requires a Qualified Domestic Relations Order under 29 U.S.C. § 1056(d)(3) — a separate order, in the plan's required form, that the plan administrator must approve; a divorce decree alone will not move the money. Military retirement has its own statute (the Uniformed Services Former Spouses' Protection Act, 10 U.S.C. § 1408) and its own trap: a servicemember's waiver of retired pay to receive VA disability benefits reduces the divisible pot, and the former spouse cannot be indemnified for the loss (Howell v. Howell, 581 U.S. 214 (2017)). Federal civil-service and state and municipal plans each have their own order forms and their own rules; never assume the QDRO template travels.

Closely held businesses — Nora's veterinary practice — require an appraisal and a fight about goodwill. Many states divide enterprise goodwill (value that would transfer to a buyer) while excluding personal goodwill (value that walks out the door with the professional), but the line and even the vocabulary vary by state, and a few states treat the whole of professional goodwill as divisible. A minority of states, following New York's O'Brien v. O'Brien, 66 N.Y.2d 576 (1985), once treated a professional license or degree itself as marital property; most rejected that approach and instead compensate the supporting spouse through a reimbursement award or support. (New York itself abandoned the O'Brien rule by statute for later-filed cases — a good reminder to check the vintage of the rule you are citing.) If the business has partners, the operative documents matter enormously — a buy-sell agreement, transfer restrictions, and the entity's structure will constrain what a court can actually order. See Running Multiple Businesses Under One Structure: A Deep Dive into Holding, Operating, and Parent Companies and The Small Business Legal Toolkit.

The marital home usually gets sold, offset, or deferred (an exclusive-occupancy order until the youngest child graduates, then a sale with a split). The mechanics of that eventual sale are ordinary real estate law: see Buying and Selling a Home: A Comprehensive Legal Guide from Contract to Closing, and when the sale actually happens, Closing a Residential Real Estate Purchase: A Practical Checklist.

Tax. Transfers of property between spouses "incident to the divorce" are nonrecognition events under 26 U.S.C. § 1041 — no gain recognized, but the transferee takes carryover basis. This means $200,000 of cash and $200,000 of appreciated stock are not equal; the toolkit-level instruction is to divide on an after-tax basis and put a basis column on the asset schedule.

Trap. Dissipation. A spouse who spends marital money on an affair, gambling, or a suspiciously generous "loan" to a relative during the breakdown can be charged with the amount as if already received. States vary on the definition and the burden. Prove it with tracing, not adjectives.

Pillar 5 — Spousal support and child support

Spousal support (alimony/maintenance) is the most discretionary award in family law. Since Orr v. Orr, 440 U.S. 268 (1979), it cannot be gender-based. Beyond that, states run on a factor test (UMDA § 308: need, ability to pay, duration of marriage, standard of living, age and health, contributions to the other's career), and a growing number now use advisory or presumptive formulas keyed to income differential and marriage length. Types include temporary (pendente lite), rehabilitative, reimbursement, durational, and — increasingly rare — permanent. The ALI's Principles of the Law of Family Dissolution (2002) reframed alimony as compensation for marriage-related loss of earning capacity, and that idea has influenced a number of state statutes. There is no national alimony rule, and there is not even a national vocabulary; read the statute.

The 2019 tax cliff is the single most important practical fact. For divorce or separation instruments executed after December 31, 2018, alimony is no longer deductible by the payor and no longer includible in the recipient's income (Tax Cuts and Jobs Act § 11051, repealing the operation of 26 U.S.C. §§ 71 and 215 for such instruments). Pre-2019 instruments keep the old treatment unless modified with an express election to adopt the new one. Every negotiation number from before 2019 is wrong now, and any state guideline formula built on the old assumption needs a haircut.

Child support is far more mechanical, and deliberately so. Federal law (42 U.S.C. § 667 and the implementing regulations) conditions state IV-D funding on adopting presumptive numeric guidelines, with written findings required to deviate. Most states use an income shares model (estimate what the intact family would have spent on the child, prorate by income); a handful use percentage of obligor income; a few use the Melson formula. Add-ons — health insurance, child care, extraordinary medical, sometimes education — sit on top. Support is modifiable on a substantial change in circumstances, and it is a duty owed to the child: parents cannot bargain it away, and a court is not bound by their agreement.

Interstate support runs on UIFSA, which every state was required to enact as a condition of federal funding, reinforced by the Full Faith and Credit for Child Support Orders Act, 28 U.S.C. § 1738B. The governing concept is continuing exclusive jurisdiction: the state that issued the order keeps the power to modify it so long as a party or the child remains there. A second state may enforce but generally may not modify. Register the order in the responding state; do not file a new one.

Enforcement. Income withholding is the default. Beyond it: contempt, license suspension, tax refund intercept, passport denial, and criminal non-support. But Turner v. Rogers, 564 U.S. 431 (2011), holds that while an indigent obligor has no automatic right to appointed counsel in civil contempt, the court must supply substitute procedural safeguards — including an express finding on ability to pay — before jailing him. And in bankruptcy, domestic support obligations are nondischargeable (11 U.S.C. § 523(a)(5)), and property-settlement obligations are likewise nondischargeable in Chapter 7 under § 523(a)(15) — though the treatment of the latter differs in Chapter 13.

Halloran-Nakashima. Nora earns $410,000; Ezra's royalties and project income average $95,000 and swing wildly. Two fights follow: whether to impute income to Ezra based on earning capacity rather than actual receipts (states do this where earnings are voluntarily suppressed, not merely lumpy), and whether Nora's distributions from the practice — as opposed to her W-2 salary — count as income for support after she has already been charged with the practice's value in the property division. That last one is the double-dip problem, and courts split on it.

Pillar 6 — Custody, parenting plans, and the UCCJEA

The standard. Every state decides custody by the best interests of the child, an open-textured test enumerated by statute (each parent's relationship with the child, stability, the child's wishes at sufficient maturity, mental and physical health, willingness to foster the other parent's relationship, and — in every modern statute — domestic violence). Two constitutional limits bound it: race may not be a determinative factor (Palmore v. Sidoti, 466 U.S. 429 (1984)), and a fit parent's decisions about third-party visitation are entitled to "special weight" (Troxel v. Granville, 530 U.S. 57 (2000)), which is why grandparent-visitation statutes must be narrowly drawn and why a court may not simply substitute its judgment for a fit parent's.

Modern practice separates legal custody (decision-making) from physical custody (residential time) and expects a written parenting plan: a schedule, a holiday rotation, a decision-making allocation, a communication protocol, a relocation clause, and a dispute-resolution step (often mediation before motion practice).

Jurisdiction is the UCCJEA, and it is not optional. The UCCJEA has been enacted in nearly every state and in the District of Columbia; Massachusetts was long the notable holdout, remaining on the older UCCJA, so confirm the current status of any state you are dealing with rather than assuming uniformity. Where enacted, it sets a strict hierarchy:

  1. Home state — where the child lived with a parent for six consecutive months immediately before the proceeding (or since birth, if under six months). Home state wins.
  2. Significant connection jurisdiction — only if there is no home state or the home state declines.
  3. More appropriate forum / last resort jurisdiction.

The issuing court then keeps exclusive continuing jurisdiction until neither the child nor a parent has a significant connection to the state, or everyone has left. The federal Parental Kidnapping Prevention Act, 28 U.S.C. § 1738A, supplies the full-faith-and-credit teeth. There are also emergency provisions for a child present in the state and threatened with abuse — but emergency jurisdiction is temporary, and practitioners regularly mistake a temporary emergency order for a permanent custody determination. It is not.

Relocation ("move-away"). The hardest custody problem there is, and the one where states diverge most. Some require the relocating parent to prove the move is in the child's best interests; others presume a primary custodian may move and place the burden on the objector; others apply a pure best-interests balancing with enumerated relocation factors. Most require written notice — often somewhere in the range of 30 to 60 days, but the number is statutory and varies — before the move. Nora's Denver directorship is precisely this case: a genuine career advancement, a real reduction in Ezra's parenting time, two children with different attachments and school situations, and a proposed compensating schedule (extended summers, all school breaks, funded travel). Which way it comes out depends on the state's presumption, so read the statute before you counsel the client to accept the job.

International abduction is governed by the Hague Convention on the Civil Aspects of International Child Abduction, implemented by ICARA, 22 U.S.C. § 9001 et seq. The petition asks for return to the child's habitual residence, not a custody determination; habitual residence is a fact-driven, totality inquiry reviewed deferentially on appeal (Monasky v. Taglieri, 589 U.S. 68 (2020)), and a court that finds a grave risk of harm has discretion — but no categorical obligation — to consider ameliorative measures before refusing return (Golan v. Saada, 596 U.S. 666 (2022)).

Pillar 7 — Parentage, paternity, and assisted reproduction

Parentage is logically prior to custody and support: you cannot allocate parenting time or order support until you know who the parents are. The Uniform Parentage Act (2017) is the modern framework — though enactment is far from universal, and many states still run on the 1973 or 2002 versions or on their own statutes. Under the UPA (2017), parentage arises through: giving birth; the marital presumption; an acknowledgment of paternity; adjudication; adoption; a valid assisted-reproduction consent; or a surrogacy agreement.

The marital presumption — a child born to a married woman is presumed the child of her spouse — is ancient, powerful, and, after Obergefell and Pavan v. Smith, 582 U.S. 563 (2017), must be applied to same-sex spouses on the same terms; a state may not refuse to put a birth mother's wife on the birth certificate when it would list a husband. The presumption is rebuttable, but many states time-bar the challenge, and a plurality of the Supreme Court in Michael H. v. Gerald D., 491 U.S. 110 (1989), sustained a state's power to make the presumption effectively conclusive in order to protect the marital family.

Unmarried fathers get constitutional protection in proportion to the relationship they have actually built. Stanley v. Illinois, 405 U.S. 645 (1972), gave an involved unwed father a hearing before his children could be taken; Lehr v. Robertson, 463 U.S. 248 (1983), held that a biological father who never grasped his "opportunity interest" — who never developed a relationship and never registered — can lose notice of an adoption. Hence putative father registries: fast, unforgiving, and jurisdiction-specific.

Voluntary acknowledgments (the VAP signed at the hospital) have the force of a judgment after a short rescission window — commonly around 60 days, subject to the state's statute — and can then be set aside only for fraud, duress, or material mistake. A man who signs one for a child he later learns is not biologically his often discovers that "not the father" is no longer a defense to support. This is one of the most consequential five minutes in American family law, and it happens in a maternity ward with no lawyer in the room.

Assisted reproduction. UPA (2017) Article 7 provides that a donor is not a parent, and that a person who consents in a signed record to assisted reproduction with intent to be a parent is one. Article 8 addresses surrogacy — gestational and genetic — with validation requirements. State law here is wildly non-uniform: some states have detailed enabling statutes with pre-birth orders, others restrict or refuse to enforce surrogacy contracts, and a few remain essentially silent. California's intent-based approach, associated with Johnson v. Calvert, 5 Cal. 4th 84 (1993), remains the touchstone in the permissive states. Never advise on surrogacy across state lines without checking both the intended parents' state and the gestational carrier's state.

Pillar 8 — Adoption

Adoption terminates one legal parent-child relationship and creates another. It comes in flavors — agency, private/independent, stepparent (the most common and the simplest), second-parent, relative, foster-to-adopt, and intercountry — and each has its own consent and procedural rules, all of them set by state statute.

The gate is termination of parental rights (TPR), either voluntary (consent, usually revocable for a short statutory window) or involuntary. Involuntary TPR carries a heightened constitutional burden: due process requires at least clear and convincing evidence (Santosky v. Kramer, 455 U.S. 745 (1982)). Grounds typically include abandonment, chronic abuse or neglect, and failure to remedy the conditions that caused removal. Under the Adoption and Safe Families Act of 1997, a state receiving federal funds must generally file (or join) a TPR petition once a child has been in foster care for 15 of the most recent 22 months, subject to enumerated exceptions.

Three overlays that catch practitioners:

  • ICWA. The Indian Child Welfare Act, 25 U.S.C. §§ 1901–1963, imposes heightened standards, active-efforts requirements, and placement preferences for the removal and adoption of an "Indian child," and it applies in state proceedings. It requires inquiry and notice to the tribe. Its application in the biological-father context was narrowed in Adoptive Couple v. Baby Girl, 570 U.S. 637 (2013), and the statute survived Commerce Clause, anticommandeering, and equal-protection challenges in Haaland v. Brackeen, 599 U.S. 255 (2023).
  • ICPC. The Interstate Compact on the Placement of Children governs placements across state lines and must be cleared before the child moves. Violating it can unwind an adoption.
  • Intercountry adoption. The Hague Adoption Convention and the Intercountry Adoption Act of 2000 govern, layered on top of immigration law — the child needs an immigrant visa, which is an immigration matter as much as a family one. See The Immigration and Citizenship Toolkit.

Finally, an adoption decree entered by a state with jurisdiction is entitled to full faith and credit in every other state; a sister state may not refuse to recognize it merely because it disagrees with the granting state's law (V.L. v. E.L., 577 U.S. 404 (2016)). Adopted children generally take under wills and intestacy statutes as the adoptive parents' issue — a fact you must reconcile with the client's existing documents. See Wills, Trusts, and Probate: A Comprehensive Estate Planning Guide.

Pillar 9 — Domestic violence and protective orders

The protective-order system is a fast, low-formality remedy bolted onto the side of family law, and it runs on a different clock than everything else in this toolkit.

The sequence is nearly universal in shape, though every number in it is set by state statute: an emergency or ex parte temporary order, obtained on a sworn petition, often the same day, on a showing of immediate danger; then a prompt return hearing — typically within a couple of weeks, but check the statute — with notice and an opportunity to be heard; then a final order, commonly lasting from one year to several and in some states permanent, on the showing of abuse the state requires (a preponderance standard in most). The relief goes far beyond "stay away": exclusive possession of the residence, temporary custody and support, no-contact terms, firearm surrender, and pet provisions.

Federal reinforcement is what gives these orders teeth:

  • The Violence Against Women Act, 34 U.S.C. § 12291 et seq., funds the system and supplies definitions. (Its private civil damages remedy was held beyond Congress's power in United States v. Morrison, 529 U.S. 598 (2000); the rest stands.)
  • 18 U.S.C. § 2265 requires states and tribes to give full faith and credit to protection orders issued elsewhere — and registration in the enforcing state may not be imposed as a precondition of enforcement.
  • 18 U.S.C. § 922(g)(8) makes it a federal crime for a person subject to a qualifying domestic-violence restraining order to possess a firearm; § 922(g)(9) does the same for a person convicted of a misdemeanor crime of domestic violence. The Supreme Court upheld § 922(g)(8) against a Second Amendment challenge in United States v. Rahimi, 602 U.S. 680 (2024).
  • 18 U.S.C. § 2261A criminalizes interstate stalking.
  • Immigration relief exists for survivors: the VAWA self-petition (8 U.S.C. § 1154(a)(1)(A)(iii)), which lets an abused spouse of a citizen or lawful permanent resident petition without the abuser; the U visa for certain crime victims who assist law enforcement; and the battery/extreme-cruelty waiver of the joint-filing requirement for removing conditions on residence under 8 U.S.C. § 1186a.

The limits, stated honestly. A protective order is a piece of paper, and Castle Rock v. Gonzales, 545 U.S. 748 (2005), held that its holder has no federal due-process property interest in police enforcement of it. Safety planning is not a legal document. And in family court, an allegation of abuse changes the custody analysis in every state — many create a rebuttable presumption against awarding custody to a perpetrator — which means these petitions must be brought truthfully and defended seriously.

Pillar 10 — Intersections: estate planning, business interests, IP, and immigration

Family law does not stay in its lane. Four intersections come up in nearly every substantial matter.

Estate planning. Marriage, divorce, and the birth or adoption of a child each silently rewrite an estate plan. Marriage typically gives a spouse an elective share (historically about one-third at common law; an augmented-estate calculation under the Uniform Probate Code, with wide state variation) that overrides a will leaving them nothing. Divorce, by statute in most states, revokes provisions in favor of the ex-spouse in a will and often in a revocable trust — but such statutes generally do not reach beneficiary designations on ERISA-governed plans, where federal preemption controls and the plan document governs. The most expensive mistake in this entire toolkit is a 401(k) that still names an ex-spouse in 2040. On divorce day, the checklist is: new will, new revocable trust, new powers of attorney and health-care directives, new beneficiary designations on every account and policy, and a QDRO. Start with The Estate Planning and Wealth Transfer Toolkit and execute with Drafting a Will: A Practical Checklist; when a parent dies mid-matter, Administering an Estate: A Probate Checklist.

Business interests. A divorce is a valuation event and a control event. Beyond the goodwill fight in Pillar 4, expect discovery into the entity, a fight over the standard of value (fair market value vs. fair value vs. investment value), and a scramble over what the operating agreement or buy-sell actually permits. Well-drafted entity documents anticipate divorce with a transfer restriction and a mandatory-purchase trigger; most do not. Asset-protection planning done before a marriage — trusts, entity layering, situs choices — is legitimate; done after a spouse files, it is a fraudulent transfer and a contempt exposure. The line and its consequences are the subject of Domestic and Offshore Asset Protection Compared: A Wealth-Defense Field Guide, and the underlying agreements are covered in The Commercial Contracts Toolkit: Drafting, Reviewing, and Enforcing Business Agreements and The Founder's Path from Formation Through Financing: A Roadmap and Resource Toolkit.

Intellectual property. Ezra's film catalog is the hard case. Copyrights created during the marriage are, in many states, marital assets — but the authorship and the statutory termination right under 17 U.S.C. § 203 are personal to Ezra and cannot simply be reassigned by a divorce decree the way a bank account can. A court can award Nora a share of the income stream; it cannot make her a co-author. Royalty streams therefore get divided by percentage-of-receipts orders, which then need enforcement mechanics — an accounting obligation, an audit right, and a security interest or wage-withholding analogue. Publicity rights and patents present the same authorship/ownership split. See Passing Down Your IP: Copyright, Patents, Publicity Rights, and Estate Planning — the transfer-at-death analysis there maps closely onto transfer-at-divorce.

Immigration. If a spouse's status derives from the marriage, divorce is an immigration event. Suppose Ezra had been a conditional permanent resident whose two-year green card came from marrying Nora. The joint I-751 petition to remove conditions is now impossible; he needs a waiver — good-faith marriage terminated by divorce, or battery/extreme cruelty, or extreme hardship — and the divorce decree becomes evidence in an immigration file. Naturalization timing shifts too: the shortened three-year path for spouses of citizens requires living in marital union with the citizen spouse. Map it with Obtaining U.S. Citizenship Through Marriage: A Step-by-Step Guide, Filing a Marriage-Based Green Card Application: An I-130 and I-485 Checklist, and, for the citizenship application itself, Naturalization: A Comprehensive Guide to the N-400 Process.

Worked example: the Halloran-Nakashima matter, end to end

Pull the pillars together on one file. Ezra files for divorce in March 2026 in the state where the family has lived since 2016 — an equitable-distribution state, for this hypothetical.

Jurisdiction (three questions, three answers). Both spouses are domiciled in the state and the durational residency period is satisfied, so the status can be dissolved. Both are personally before the court, so the money is reachable. The children have lived in the state for ten years, so it is unambiguously the UCCJEA home state — which is exactly why Nora must not move to Denver with the children before a custody determination. If she does, the home state does not follow her; the state keeps exclusive continuing jurisdiction, and her unilateral move becomes Exhibit A in a best-interests analysis.

The prenup. Ezra moves to set it aside: eleven days, no independent counsel, and a disclosure schedule that listed Nora's practice at book value. He loses the "unconscionable when made" argument — the deal was not shocking on its face in 2014 — but the disclosure attack has real force, because book value on a professional practice is not fair and reasonable disclosure of its value. The court severs the spousal-support waiver as procedurally defective and enforces the separate-property characterization of each business, but not the clause purporting to sweep in all appreciation. Net effect: Nora's practice stays hers, but the marital estate can reach its marital-period growth. Everything about this outcome would change in a Simeone state.

The asset schedule. Marital home with $340,000 of equity. Nora's 401(k), $520,000. Ezra's SEP-IRA, $110,000. A joint brokerage account holding $200,000 of stock with a $60,000 basis. Marital-period appreciation in the veterinary practice, appraised at $480,000 of enterprise goodwill plus hard assets, with the personal-goodwill component excluded. Ezra's film copyrights, generating $95,000/year of lumpy royalties.

Two lessons fall straight out of this schedule. First, the basis column matters: the $200,000 brokerage position is worth roughly $170,000 after tax at a 15% rate on the $140,000 of gain, so trading it against $200,000 of home equity is a real loss for whoever takes the stock. Under 26 U.S.C. § 1041 the transfer itself is tax-free, but the built-in gain travels with the asset. Second, the 401(k) needs a QDRO — a decree line saying "Ezra receives $200,000 of Nora's 401(k)" moves no money at all until a separate order, in the plan's form, is entered and accepted by the plan administrator.

Support. Ezra earns $95,000 on average; Nora's W-2 salary is $410,000, plus practice distributions. Nora argues for imputing more income to Ezra; she loses, because lumpy is not the same as suppressed, and he has not left the field. Ezra argues that Nora's distributions count as income for support; Nora answers double-dip — she has already been charged with the value of the practice in the property column. The court splits the difference in the way many do: distributions that are genuinely a return on the capitalized value are excluded, distributions that are really compensation for her labor are counted. This is a fight about the appraiser's normalization of her salary, not about family law doctrine, which is why the appraisal is the whole case.

The move-away. Nora accepts the Denver directorship contingent on the court's ruling — the right sequence. She gives statutory written notice. Her proposed plan gives Ezra all school breaks, eight weeks of summer, and funds the travel. Wren (9) has deep school and team ties; Kit (5) does not. In a state that presumes a primary custodian may relocate, Nora likely prevails with a compensating schedule. In a state that puts the burden on the relocating parent to show the move serves the children's best interests, this is a genuinely close case and she may lose Wren. The identical facts produce opposite outcomes in neighboring states, which is the single most important thing this toolkit has to teach.

The day the decree enters. Both 2015 estate plans still name the other spouse as executor, agent, primary beneficiary, and trustee. The state's revocation-on-divorce statute cleans up the wills automatically. It does not clean up Nora's 401(k) designation, which is governed by the plan document under ERISA. If Nora dies in 2031 without having submitted a new beneficiary form, her ex-husband may well collect $520,000 that she intended for her children. This is the most expensive five minutes of paperwork in the whole matter, and it is the one nobody calendars.

The landscape as a working checklist

Run this gate by gate on any family matter.

Status and agreements

  • [ ] Is there a valid marriage — license, capacity, solemnization? Any common-law marriage exposure from a prior state of residence?
  • [ ] Is there a premarital or marital agreement? Get the executed original, the disclosure schedules, and the choice-of-law clause.
  • [ ] Stress-test it on all four axes: formalities, voluntariness, disclosure, unconscionability (when made — and, in minority states, at enforcement).
  • [ ] Confirm it does not purport to fix child support or custody. Those clauses do not bind the court.

Jurisdiction (three separate questions — answer all three)

  • [ ] Status: domicile plus the durational residency period. Confirm the exact period in your state.
  • [ ] Money: personal jurisdiction over the responding spouse. If absent, expect a divisible divorce.
  • [ ] Children: UCCJEA home-state analysis. Six months. Do this first, not last.
  • [ ] Any existing support order elsewhere? Check UIFSA continuing exclusive jurisdiction before filing anything new.

Property

  • [ ] Community property or equitable distribution? Confirm the valuation date rule.
  • [ ] Complete asset and liability schedule, with a basis column and a characterization column.
  • [ ] Trace every separate-property claim to a document. Commingling defeats assertion.
  • [ ] Retirement: is a QDRO required? Is any of it military (10 U.S.C. § 1408) or a government plan with its own order form?
  • [ ] Business: appraisal, standard of value, enterprise vs. personal goodwill, buy-sell constraints.
  • [ ] Any dissipation? Document it with tracing, not narrative.
  • [ ] Divide on an after-tax basis (26 U.S.C. § 1041 carryover basis).

Support

  • [ ] Run the state child-support guideline. Written findings required for any deviation.
  • [ ] Income determination: imputation, variable/self-employment income, the double-dip question.
  • [ ] Spousal support: factor test or formula? Type and duration?
  • [ ] Confirm the post-2018 tax treatment in every number you quote.
  • [ ] Security: life insurance, wage withholding, and an enforceable arrears mechanism.

Children

  • [ ] Parenting plan: legal custody, physical schedule, holidays, decision-making, communication, relocation clause, dispute-resolution step.
  • [ ] Relocation: what is your state's presumption and notice period? Answer before the client accepts the job.
  • [ ] Domestic violence allegations: does your state impose a rebuttable presumption against custody?
  • [ ] Parentage established as to every child — marital presumption, VAP, adjudication, or adoption?

Safety

  • [ ] Any need for an emergency or ex parte protective order? Calendar the return hearing immediately.
  • [ ] Firearm surrender under 18 U.S.C. § 922(g)(8) and state law.
  • [ ] Out-of-state order? It is entitled to enforcement under 18 U.S.C. § 2265 without a registration precondition.

Aftercare — the day the decree enters

  • [ ] New will, trust, power of attorney, health-care directive.
  • [ ] Every beneficiary designation: 401(k), IRA, pension, life insurance, HSA, transfer-on-death accounts.
  • [ ] QDRO drafted, entered, and accepted by the plan administrator.
  • [ ] Deeds, titles, and refinancing executed — a decree ordering a transfer is not a deed.
  • [ ] Credit and joint debt separated. Name-change filings. Immigration consequences addressed.
