Client Trust Accounting and IOLTA Compliance: A Practical Checklist

Type: Checklist
Jurisdiction: National
Date: 2024-05-09
Topic: Legal Ethics

Trust accounting generates more attorney discipline than almost any other area of practice, and it does so because the rule is close to strict liability: a shortage in the account is a violation whether or not the lawyer meant to take a dime. This checklist walks the whole lifecycle — opening the IOLTA and non-IOLTA accounts, the absolute bar on commingling and its one narrow exception, what belongs in trust and what does not, the sharply divergent state treatment of flat fees and "nonrefundable" retainers, individual client ledgers, the monthly three-way reconciliation, the prohibition on disbursing against uncollected funds, earned-fee transfers, disputed funds, third-party liens, credit-card processors, escheat of unclaimed money, and recordkeeping. It flags the traps that actually catch practitioners: the bookkeeper nobody supervises, the flat fee dropped into operating, the settlement check disbursed before it clears, the chargeback that reaches into trust. Every ethics rule cited here is an ABA Model Rule, which is a model and binds no one until a jurisdiction adopts it; your state's version, its recordkeeping periods, its IOLTA program, and its audit regime control, and California's rules differ notably from the Model Rules. Use this as a working operational checklist, then reconcile it against your own supreme court's rules and verify current requirements before relying on any period or figure stated here.

Client Trust Accounting and IOLTA Compliance: A Practical Checklist

Legal Ethics > Law Practice Management | Published 9 May 2024 - Updated 22 September 2025 | UpLaw - uplaw.us

Most lawyers who lose their license over trust accounting never intended to steal anything. They intended to be busy. The rule does not care about the difference — and the arithmetic does not forgive.

Keywords: client trust account, IOLTA, Model Rule 1.15, commingling, three-way reconciliation, client ledger, advance fee, flat fee, nonrefundable retainer, disputed funds, settlement liens, uncollected funds, trust audit, escheat, attorney discipline

Before you start: the one thing to understand

Every rule in this checklist descends from a single, unglamorous proposition: money that is not yours must be kept where you cannot spend it, and you must be able to prove at any moment exactly whose it is. ABA Model Rule 1.15 says it in a paragraph. Disciplinary dockets spend thousands of pages explaining what happens when lawyers don't.

Two framing warnings before the phases.

First, the Model Rules are a model. They bind no one until a jurisdiction adopts them. Nearly every state has adopted some version of Rule 1.15, but the details that matter most to you — the recordkeeping retention period, whether flat fees may go into your operating account, whether your bar runs random audits, whether you must register your trust accounts annually — are set by your own supreme court and differ materially from state to state. California, for example, amended its Rule 1.15 and layered on the Client Trust Account Protection Program, which requires annual registration of trust accounts and a compliance self-assessment; New York requires seven years of records where the Model Rule says five. Read your state's rule before you rely on anything below. The broader framework is laid out in Legal Ethics and Professional Responsibility: A Comprehensive Guide to the Model Rules.

Second, this is nearly strict liability. Discipline for trust violations does not require an intent to steal. A negligent shortage is a violation. A bookkeeper's embezzlement is your violation, because Model Rules 5.1 and 5.3 make you responsible for supervising nonlawyer assistants. And where knowing misappropriation is found, the sanction in many jurisdictions is presumptively disbarment regardless of restitution, remorse, or an otherwise spotless career — the classic statement is In re Wilson, 81 N.J. 451 (1979), where the New Jersey Supreme Court held that knowing misappropriation of client funds will almost invariably result in disbarment. Other states are less absolute, but none are forgiving.

Meet Delia Marchetti, our running example: a capable third-year solo who left a mid-size firm to open Marchetti Law LLC. She is a good lawyer. Her trust account is about to end her career, and she still does not know it.

Phase 1 — Understand the rule before you touch the money

[ ] Pull your jurisdiction's version of Rule 1.15 and read it start to finish, including comments.
[ ] Pull your jurisdiction's trust-account recordkeeping rule (often a separate rule or an appendix modeled on the ABA Model Rules for Client Trust Account Records).
[ ] Identify who in your state receives overdraft notifications from your bank, and confirm your bank is on the approved-institution list.
[ ] Confirm whether your state requires annual trust-account registration or self-certification.
[ ] Read your state bar's trust-accounting handbook and its recent discipline summaries.
[ ] Calendar a standing monthly reconciliation appointment. Treat it like a court date.

Why it matters, and the traps. Model Rule 1.15(a) requires a lawyer to hold client and third-party property "separate from the lawyer's own property," to keep complete records, and to preserve those records for five years after the representation ends. Model Rule 1.15(b) permits the lawyer's own funds in trust only to pay bank service charges, and only in the amount necessary. Model Rule 1.15(c) requires advance fees and expenses to be deposited in trust and withdrawn only as earned or incurred. Model Rule 1.15(d) requires prompt notice, prompt delivery, and a full accounting on request. Model Rule 1.15(e) requires disputed property to stay put until the dispute resolves.

The trap in Phase 1 is assuming you know this because you passed the MPRE. You did not learn your state's overdraft-notification rule on the MPRE. Nearly every jurisdiction now requires trust-account banks to report any overdraft or dishonored instrument directly to disciplinary counsel — not to you. A single bounced trust check opens a file. There is no cure period and no chance to explain it away first.

Phase 2 — Set up the accounts

[ ] Open a pooled IOLTA account at an eligible financial institution in the state where you practice.
[ ] Confirm the bank has an IOLTA agreement with your state's program and remits interest directly to it.
[ ] Title the account exactly as your rule requires (typically "[Firm] Client Trust Account" or "IOLTA Trust Account") — not "Business Account 2."
[ ] Confirm the account is not subject to service charges that can be swept against principal, and that any fees hit your operating account.
[ ] For any single client's funds that are large enough or will be held long enough to earn net interest for that client, open a separate interest-bearing account for that client, with interest payable to the client.
[ ] Open a separate operating account for firm money. Never the same bank product, never the same debit card.
[ ] Order checks and deposit slips that are visually distinct from operating-account stock.
[ ] Disable overdraft protection and any sweep, line-of-credit, or auto-transfer feature tied to the trust account.
[ ] Never issue an ATM or debit card on the trust account; many states flatly prohibit cash withdrawals from trust.

Why it matters, and the traps. IOLTA — Interest on Lawyers' Trust Accounts — solves a plumbing problem. Client funds that are individually small or short-held cannot practically earn net interest for any one client after bank and accounting costs. Pooling them lets the aggregate earn interest, which is remitted to a state foundation that funds legal aid. The Supreme Court has twice confronted the program: Phillips v. Washington Legal Foundation, 524 U.S. 156 (1998), held that interest earned on client funds in an IOLTA account is the client's property for Fifth Amendment purposes; Brown v. Legal Foundation of Washington, 538 U.S. 216 (2003), held that the taking was nonetheless constitutional because just compensation is measured by the owner's net loss, which in a properly administered program is zero.

That holding is also the operational test you must apply in practice. The decision whether a given client's money goes into IOLTA or into a separate interest-bearing account is not discretionary. If the funds are large enough or will be held long enough to generate net interest for that client after costs, they belong in a client-specific account with the interest going to the client. Park a $900,000 escrow in IOLTA for eight months and you have not been generous to legal aid; you have converted your client's interest.

Delia's mistake in Phase 2 is smaller and more common. She opened her IOLTA at the same bank as her operating account, kept overdraft protection on both, and linked them. Nine months later, a $2,300 operating-account shortfall auto-swept from trust. She never saw the notice. Disciplinary counsel did.

Firms building their back office from scratch should think about the accounting stack itself as an ethics decision — see Running a Law Practice on Open Source Software: A Practical Guide and The Open-Source Law Firm: Building a Cost-Effective, Ethics-Compliant Technology Stack.

Phase 3 — Never commingle

[ ] Deposit zero firm funds into trust, with one exception: a small, documented cushion for bank service charges where your rule permits it.
[ ] Record that cushion on its own ledger, labeled as firm funds, and reconcile it like any other ledger.
[ ] Never deposit client funds into operating "temporarily."
[ ] Never pay a firm expense — rent, payroll, your own credit card — from trust, ever, for any reason.
[ ] Never "borrow" from trust, even overnight, even with the intent to replace it, even if the client would consent.
[ ] Leave no earned fee sitting in trust after it is earned and undisputed; that is commingling in the other direction.

Why it matters, and the traps. Commingling is a violation in itself, independent of any loss. Nobody has to be harmed. The reason is evidentiary: once firm money and client money are in the same pot, no one — not you, not an auditor, not a court — can say whose dollars were spent when the pot goes down. The rule refuses to let you create that ambiguity.

The two exceptions people misremember: (1) the bank-charge cushion in Model Rule 1.15(b), which is narrow and must be minimal; and (2) nothing. There is no second exception. "The client said it was fine" is not a defense — the rule protects the integrity of the system, not just the individual client, and it is not waivable by client consent.

The under-appreciated trap is the reverse commingling: leaving earned fees parked in trust because it feels safe, or because you want to keep the balance up, or because you have not gotten around to the transfer. Money that is yours, sitting in trust, is your money in the client trust account. That is the definition of commingling. It also makes your trust balance untrue, which sabotages every reconciliation you run.

Phase 4 — Know what goes in

[ ] Advance fees (money paid before the work is done) → trust.
[ ] Advance costs and expenses (filing fees, deposition deposits, expert retainers) → trust.
[ ] Settlement proceeds and judgment payments → trust.
[ ] Real estate escrows, closing funds, and earnest money → trust (and see your state's separate escrow rules).
[ ] Third-party funds you hold (lienholder shares, funds held pending an escrow condition) → trust.
[ ] Retainer replenishments under an evergreen agreement → trust.
[ ] Earned fees, reimbursements of costs you already fronted, and referral fees payable to you → operating, not trust.
[ ] Fee agreements: state in writing what goes into trust, how and when funds will be withdrawn, and what the client will receive. Model Rule 1.5(b).

Why it matters, and the traps. The taxonomy is simple until a single check contains both categories. Delia receives a $60,000 settlement check for her client, Ms. Okonkwo. It contains: the client's net recovery, Delia's one-third contingency fee, $4,100 in costs Delia advanced out of firm funds, and a $9,300 hospital lien. The entire check goes into trust. You deposit the whole instrument, wait for it to clear, then disburse each component out of trust to its rightful owner — including, last, your own fee. You do not endorse a settlement check into operating and then write the client a check from operating. That is commingling on arrival.

Costs are where good lawyers get sloppy. If the client advanced $3,000 for expert fees, that $3,000 is client money in trust and it may be spent only on that client's expert. It is not a general expense fund and it is not available to cover another client's filing fee, even for a week. Cost handling in contingency matters is a recurring theme in Evaluating a Personal Injury Claim: A Practical Checklist.

Phase 5 — Flat fees and "nonrefundable" retainers

[ ] Identify which of your fee structures are advance fees (payment for work not yet done) — those are client money.
[ ] Identify whether any are true (general) retainers — payment purely for availability, earned on receipt, not credited against hourly work.
[ ] Check your state's rule on flat fees before you deposit a single one. Jurisdictions diverge sharply.
[ ] Stop using the word "nonrefundable" in fee agreements. It is at best meaningless and at worst an independent violation.
[ ] If your state permits a flat fee in the operating account, comply with every condition — typically a written agreement, a disclosure that the client may discharge you and receive a refund of any unearned portion, and often a right to elect trust deposit.
[ ] Define, in writing, the milestones at which portions of a flat fee become earned.
[ ] Confirm your obligation under Model Rule 1.16(d) to refund any unearned portion on termination, no matter what the agreement says.

Why it matters, and the traps. This is the single sharpest state-law fault line in trust accounting, and it is exactly where Delia falls.

Delia takes a $7,500 flat fee to defend Mr. Halvorsen on a felony charge. Her engagement letter calls it "a nonrefundable flat fee, earned upon receipt." She deposits it into her operating account on the day it arrives and pays her rent from it. Two weeks later, before she has filed an appearance, Halvorsen retains other counsel and demands his money back. Delia has spent it.

She now has three problems, not one. The refund problem is the smallest. The second is that in most jurisdictions the fee was an advance fee — client property — that belonged in trust until earned, so she has misappropriated client funds. The third is that the label itself may violate the fee rules: ABA Formal Opinion 505 (2023) concluded that fees paid in advance must be placed in a client trust account and withdrawn only as earned, and that labels such as "nonrefundable" or "earned upon receipt" do not change the character of the money or defeat the client's right to a refund of the unearned portion.

Courts got there first. Matter of Cooperman, 83 N.Y.2d 465 (1994), held that special nonrefundable retainer agreements are unenforceable as against public policy because they chill the client's absolute right to discharge counsel. In re Sather, 3 P.3d 403 (Colo. 2000), held that advance fees remain client property until the lawyer earns them by conferring a benefit or performing services.

But — and this is the whole point of the phase — some jurisdictions do permit a properly disclosed flat fee to be deposited into the operating account, subject to written conditions and the client's continuing right to a refund. Others require trust deposit without exception. Do not import the practice you learned in one state into another. Look it up. If you cannot resolve it in ten minutes, put the money in trust: trust deposit is never the violation. The worst that happens is you are conservative.

Fee scope and fee agreements interact with everything else in a matter's lifecycle; see also Withdrawing From a Representation: A Practical Checklist, which covers the refund obligation on the way out the door.

Phase 6 — Keep individual client ledgers

[ ] Maintain a separate ledger for every client and every matter holding funds.
[ ] Each ledger entry records: date, payor/payee, amount, purpose, and running balance.
[ ] Maintain a ledger for the firm's bank-charge cushion if you hold one.
[ ] No client ledger may ever go negative. Not for an hour.
[ ] Reconcile the sum of all client ledgers to the trust account balance every month.
[ ] Retain the underlying source documents: deposit slips, cancelled checks (front and back), wire confirmations, disbursement authorizations, settlement statements.

Why it matters, and the traps. The individual ledger is the entire ballgame. The bank tells you how much money is in the account. Only the ledgers tell you whose it is. A trust account can be perfectly balanced against the bank statement and still be a disciplinary catastrophe, because Client A's money is quietly funding Client B's disbursement.

That is exactly what a negative client ledger means, and it is the most-missed violation in practice. If Ms. Okonkwo's ledger shows $400 but you cut a $1,200 check for her deposition transcript, you have not overdrawn the account — there is plenty of other clients' money in it — so no check bounces, no overdraft notice fires, and nothing looks wrong. But you have just spent $800 of somebody else's money. That is a technical misappropriation, and an auditor will find it in about ninety seconds. Never disburse more for a client than that client's ledger holds.

Phase 7 — The monthly three-way reconciliation

[ ] Every month, within days of the bank statement, reconcile three figures:
- [ ] (1) the adjusted bank balance (statement balance, plus deposits in transit, minus outstanding checks);
- [ ] (2) the book balance in your trust check register / accounting system;
- [ ] (3) the sum of all individual client ledgers.
[ ] All three must be identical. Not close. Identical.
[ ] Investigate any discrepancy the same week. Do not "carry it forward."
[ ] Review the outstanding check list and chase anything over 90 days old.
[ ] Scan every client ledger for negatives and for stale balances.
[ ] Sign and date the reconciliation, and keep it. Have a second person review it if you have one.
[ ] Store reconciliations for the full retention period.

Why it matters, and the traps. Two-way reconciliation — bank statement to check register — is what most small firms actually do, and it catches almost nothing. It will tell you that your record of the account matches the bank's record of the account. It will not tell you that you are $8,000 short of what you owe your clients in the aggregate, or that Mr. Halvorsen's ledger has been negative since March. Only the third leg does that.

The three-way reconciliation is where fraud dies. It is also, invariably, the step that gets skipped in a busy month, then two busy months, then a quarter. A firm that reconciles three ways every month, on time, in writing, essentially cannot develop a catastrophic trust problem, because the arithmetic surfaces the error while it is still a hundred-dollar error.

The supervision trap: delegating reconciliation to a bookkeeper does not delegate the responsibility. Model Rules 5.1 and 5.3 make you answerable for nonlawyer assistants' conduct. The classic disciplinary fact pattern is an embezzling office manager and a lawyer who signed nothing, reviewed nothing, and lost their license anyway. You review and sign the reconciliation. You look at the bank statement with your own eyes. You keep signature authority.

Phase 8 — Never disburse against uncollected funds

[ ] Before disbursing, confirm the deposited instrument has actually cleared — not merely that the funds are "available."
[ ] Know the difference: Regulation CC (12 C.F.R. Part 229), implementing the Expedited Funds Availability Act, 12 U.S.C. § 4001 et seq., requires banks to make funds available on a schedule. Availability is not collection. A check can be available on day two and be returned as counterfeit in week six.
[ ] For large or unfamiliar instruments, ask the bank to confirm final collection in writing.
[ ] Treat wires as the safe instrument; treat cashier's checks from unknown parties as high risk, not low risk.
[ ] Verify wire instructions by telephone, using a number you already had — never a number in the email.
[ ] Never disburse from Client A's cleared funds to cover Client B's uncleared deposit.

Why it matters, and the traps. This is the modern collection-scam fact pattern, and it has destroyed solos who did nothing else wrong. The pitch arrives as a legitimate-sounding engagement — a debt collection, an overseas judgment, a commercial settlement. A "cashier's check" for $180,000 arrives. It is deposited into trust. The bank makes the funds available. The "client" urgently asks you to wire their share, less your fee, to an offshore account. You do. Three weeks later the check is returned as counterfeit and your trust account is $180,000 short — meaning every other client's money in that account is gone. You now have a misappropriation, and the fact that you were also a victim is not a defense to the shortage.

The sibling trap is business email compromise on a real closing: an intruder sits in an email thread and sends revised wire instructions the day before funding. The money leaves trust to a criminal. ABA Formal Opinion 477R (2017) addresses the duty to use reasonable security when communicating client information, and ABA Formal Opinion 483 (2018) addresses the lawyer's obligations after an electronic data breach — including notifying affected clients. If your trust account or client funds are touched, this becomes an incident-response problem as much as an accounting one: see Responding to a Data Breach: A Notification and Incident Response Checklist and Data Breach Notification Law: A Comprehensive Guide.

Rule of thumb, and it costs nothing: wait for collection, and call the number you already had.

Phase 9 — Transferring earned fees

[ ] Do the work. Bill the work.
[ ] Send the client an invoice or written statement describing the services and the amount to be withdrawn from trust.
[ ] Wait the period your rule or agreement provides (many firms use a short notice window even where none is required) so the client can object.
[ ] Transfer the earned amount to operating by a check or transfer payable to the firm — never cash, never a debit card.
[ ] Post the withdrawal to the client's individual ledger on the day it happens.
[ ] Transfer only what is earned. If in doubt, transfer less.
[ ] Never take a fee in a lump "catch-up" transfer covering several clients at once. One client, one transfer, one ledger entry.

Why it matters, and the traps. Model Rule 1.15(c) allows withdrawal "only as fees are earned or expenses incurred," and Model Rule 1.4 requires you to keep the client reasonably informed. The documentation is what converts a withdrawal from an accusation into a record.

The trap is the round-number transfer at month-end. Delia bills roughly $4,000 a month and needs $4,000 to make payroll, so she transfers $4,000 out of trust and tells herself she will reconcile it against actual time entries later. If the earned amount was $3,600, she has taken $400 of client money. She will do this eleven more times. By December she is short several thousand dollars and cannot say to whom it belongs. This is how ordinary lawyers become misappropriators — not with a decision, but with a habit.

The other trap: transferring a fee out of a matter where the fee is contested. The moment a client disputes a bill, that money is disputed property. See Phase 10.

Phase 10 — Disputed funds stay in trust

[ ] The moment a client disputes a fee or a disbursement, freeze the disputed amount in trust.
[ ] Withdraw the undisputed portion (the client's undisputed net recovery; your undisputed earned fee) promptly — do not hold hostage what nobody contests.
[ ] Notify the client in writing of the amount held and the reason.
[ ] Attempt resolution; consider your bar's fee arbitration program, which many states offer and some mandate at the client's election.
[ ] If the dispute persists, consider interpleader and deposit the funds with a court.
[ ] Never self-help. Do not take the fee and dare the client to sue you.
[ ] Document every step, because a fee dispute frequently ripens into a grievance.

Why it matters, and the traps. Model Rule 1.15(e) is explicit: when two or more persons claim an interest in property the lawyer holds, the property "shall be kept separate by the lawyer until the dispute is resolved," and the undisputed portion shall be distributed promptly.

The trap is emotional. You did the work. The client is being unreasonable. The money is sitting right there. Take it and you have converted a fee dispute — which you might well have won — into a misappropriation charge, which you will lose. The disciplinary system draws a bright line between a lawyer who is owed money and a lawyer who took money. Stay on the right side of it, and remember the corollary: freezing the entire balance when only part is disputed is also a violation. You must release the undisputed money.

Fee disputes and withdrawal travel together; a client who challenges a bill is often a client who is leaving. Run the sequence in Withdrawing From a Representation: A Practical Checklist alongside this phase.

Phase 11 — Third-party claims and liens

[ ] Before disbursing any settlement, identify every perfected lien and statutory claim: health-care provider liens, hospital liens, Medicare, Medicaid, ERISA plan reimbursement, workers' compensation carriers, child-support arrears, judgment creditors, prior counsel's charging lien.
[ ] Determine which claims are legally enforceable in your state and which are mere requests.
[ ] Hold the disputed or unresolved lien amount in trust; do not disburse it to the client.
[ ] Negotiate reductions in writing; get a release or payoff letter before you cut the check.
[ ] Prepare a written settlement statement itemizing gross recovery, fee, costs, each lien payment, and net to client — and get the client's signature.
[ ] If liens exceed the fund or are irreconcilable, interplead.

Why it matters, and the traps. Model Rule 1.15(d) requires prompt delivery to "a client or third person" of funds they are entitled to receive. The lawyer who pays the client the whole net and lets the client "handle the hospital" has, in a state recognizing that lien, disbursed money belonging to someone else. The lienholder sues, and the lawyer pays personally — and gets disciplined.

The federal overlay is real. The Medicare Secondary Payer Act, 42 U.S.C. § 1395y(b), gives the United States a right of recovery against settlement proceeds with a meaningful enforcement posture. ERISA plan reimbursement is governed by a line of Supreme Court cases that turn on the specific identifiable fund: Sereboff v. Mid Atlantic Medical Services, Inc., 547 U.S. 356 (2006), permitted equitable enforcement against an identified fund; US Airways, Inc. v. McCutchen, 569 U.S. 88 (2013), held that the plan's written terms govern; and Montanile v. Board of Trustees of the National Elevator Industry Health Benefit Plan, 577 U.S. 136 (2016), held that once the beneficiary dissipates the fund into general assets, the plan cannot pursue the beneficiary's general assets under ERISA § 502(a)(3). Read Montanile carefully. It is not a license to dissipate — it is a warning about how much turns on the fund staying identifiable in trust, and about the pressure a plan will put on the lawyer holding it.

Aggregate settlements raise their own layer of allocation and disclosure duties; the mechanics of court-supervised distribution are covered in Settling a Class Action: A Rule 23(e) Approval Checklist and Class Action Litigation: A Comprehensive Guide to Rule 23.

Phase 12 — Credit cards, processors, and chargebacks

[ ] Use a payment processor built for law firms that supports split deposits — earned fees to operating, advance fees to trust.
[ ] Configure the processor so that all fees, discount rates, and monthly charges are debited from the OPERATING account, never from trust.
[ ] Confirm the processor will never reach into trust to satisfy a chargeback or a negative balance. Get it in writing.
[ ] Never run a single card transaction that mixes earned fees and trust deposits.
[ ] Reconcile processor settlement reports to trust deposits monthly — settlement timing lags, and the lag creates phantom balances.
[ ] Check your state's rule and ethics opinions on surcharging clients for card fees; treatment varies.

Why it matters, and the traps. Card processing is a commingling machine if you let it be. The default configuration of a general-purpose processor takes its cut off the top of every deposit. Applied to a trust deposit, that means a client's $5,000 advance fee lands as $4,855 — you are now $145 short on that client's ledger from the instant of deposit, through no act of your own. Multiply by a year.

The chargeback is worse. A client disputes a charge months later; the processor claws back the funds. If your processor is authorized to debit the trust account, it will take other clients' money to satisfy the reversal. Configure the account so this is impossible before you accept your first card.

Phase 13 — Unclaimed funds and escheat

[ ] Every month, review client ledgers for stale balances — money you are holding for a client you cannot reach, or a $12 residue nobody wants.
[ ] Make and document reasonable efforts to locate the owner: last known address, phone, email, a skip-trace where the amount justifies it.
[ ] Do not absorb the money into fees "because it's small," and do not donate it, and do not leave it in trust forever.
[ ] Follow your state's unclaimed property procedure. Most states have enacted a version of the Uniform Unclaimed Property Act (revised in 2016 as RUUPA), with a dormancy period after which the funds must be reported and remitted to the state.
[ ] Check whether your state has a lawyer-specific alternative — several permit unclaimed client funds to be remitted to the IOLTA/legal-services foundation instead of the general escheat authority.
[ ] Keep the ledger and supporting documentation after remittance; you may have to prove where the money went.

Why it matters, and the traps. Unclaimed balances feel like a nuisance, and lawyers dispose of them the way one disposes of nuisances — quietly. That instinct is a conversion. Sweeping a $60 residue into fees is misappropriation of $60, and the amount is not the point; the disciplinary system reads it as a statement about your relationship to money that is not yours. Dormancy periods and procedures are set by state law and vary; look yours up once and build it into the monthly review.

Phase 14 — Recordkeeping, retention, and the audit

[ ] Retain, for the full period your state requires: bank statements, cancelled checks (front and back), deposit slips and items, wire confirmations, the trust check register, all individual client ledgers, all signed monthly three-way reconciliations, fee agreements, invoices supporting every fee withdrawal, and signed settlement statements.
[ ] Retention period: Model Rule 1.15(a) says five years after the end of the representation. Your state may say more (New York, for example, requires seven). Confirm yours.
[ ] Store records so they survive a laptop failure, a ransomware event, and your death. Encrypt them; back them up; test the restore.
[ ] Name a successor in your succession plan who can access trust records and wind down the account.
[ ] If your state runs random audits or requires annual trust-account registration or self-assessment, calendar it as a hard deadline.
[ ] Assume you will be audited. Keep the file such that you could hand it over tomorrow with no preparation.

Why it matters, and the traps. An audit is not an investigation into whether you are honest. It is an investigation into whether you can prove it. Auditors reconstruct the account. When records are missing, the presumption does not run your way — the inability to account for client funds is itself a violation in most jurisdictions, wholly apart from whether anything is actually missing. The lawyer who says "the money is all there, I just never kept ledgers" has already conceded the case.

Practical note on confidentiality: trust records contain client information, and disclosure to disciplinary authorities in a lawful audit is contemplated by the rules. But how you store them implicates Model Rules 1.1 (competence, including technological competence) and 1.6(c) (reasonable efforts to prevent unauthorized disclosure). Cloud accounting is fine; unencrypted cloud accounting with a reused password is not.

Common Mistakes to Avoid

The flat fee in the operating account. Delia's original sin. In most jurisdictions an advance fee is client property until earned, and no adjective in your engagement letter changes that. When in doubt, deposit to trust.
The two-way reconciliation. Matching your register to the bank statement proves nothing about whose money it is. Only the client-ledger leg does.
The unsupervised bookkeeper. Model Rules 5.1 and 5.3 mean the theft is still your violation. Review and sign the reconciliation yourself; keep sole signature authority.
The negative client ledger. No check bounces, no alarm sounds, and you have still spent another client's money.
Disbursing against uncollected funds. "Available" is not "collected." Regulation CC availability schedules are a banking convenience, not a guarantee of finality.
Round-number month-end fee transfers. Take exactly what you earned, documented by an invoice, or take less.
Self-help on a disputed fee. You may have been right about the bill. You will still lose the disciplinary case.
Leaving earned fees in trust. Commingling runs both directions.
Linked accounts, overdraft protection, sweeps, and debit cards. Automate nothing that can move money out of trust without a human decision.
Processor fees and chargebacks hitting trust. A misconfiguration on day one becomes a shortage on every deposit thereafter.
Ignoring liens. Paying the client the lienholder's share is disbursing someone else's money — and Montanile is not a safe harbor.
Sweeping small unclaimed balances into fees. Escheat exists. Use it.
Assuming the Model Rules are the rules. They are a model. Your supreme court's version, retention period, and audit program control.

Primary Authority

ABA Model Rule of Professional Conduct 1.15 (Safekeeping Property) — separate accounts; records preserved five years after termination; bank-charge exception; advance fees and expenses in trust and withdrawn only as earned or incurred; prompt notice, delivery, and accounting; disputed property held separate. A model only; your jurisdiction's adopted rule controls.
ABA Model Rules for Client Trust Account Records — the model recordkeeping regime (ledgers, reconciliations, source documents) from which most state recordkeeping rules derive.
ABA Model Rule 1.5 (fees; written communication of the basis of the fee) and Model Rule 1.16(d) (refund of any advance payment of fee not earned on termination).
ABA Model Rules 1.4 (communication), 1.1 and 1.6(c) (competence, including technological competence, and safeguarding client information), 5.1 and 5.3 (responsibility for lawyers and nonlawyer assistants), 8.4(c) (dishonesty, fraud, deceit, misrepresentation).
ABA Formal Opinion 505 (2023) — advance fees are client property, must be held in trust, and cannot be made "nonrefundable" or "earned upon receipt" by label.
ABA Formal Opinion 477R (2017) and ABA Formal Opinion 483 (2018) — securing client communications, and obligations following an electronic data breach.
Phillips v. Washington Legal Foundation, 524 U.S. 156 (1998) — interest earned on client funds held in IOLTA is the client's property for Fifth Amendment purposes.
Brown v. Legal Foundation of Washington, 538 U.S. 216 (2003) — IOLTA programs are constitutional; just compensation is measured by the client's net loss, which is zero where the funds could not have earned net interest for the client individually.
Matter of Cooperman, 83 N.Y.2d 465 (1994) (N.Y.) — "special nonrefundable retainer" agreements are unenforceable as against public policy.
In re Sather, 3 P.3d 403 (Colo. 2000) — advance fees remain client property until earned.
In re Wilson, 81 N.J. 451 (1979) (N.J.) — knowing misappropriation of client funds will almost invariably result in disbarment.
ERISA reimbursement line: Sereboff v. Mid Atlantic Medical Services, Inc., 547 U.S. 356 (2006); US Airways, Inc. v. McCutchen, 569 U.S. 88 (2013); Montanile v. Board of Trustees of the National Elevator Industry Health Benefit Plan, 577 U.S. 136 (2016).
Medicare Secondary Payer Act, 42 U.S.C. § 1395y(b) — federal recovery rights against settlement proceeds.
Expedited Funds Availability Act, 12 U.S.C. § 4001 et seq., and Regulation CC, 12 C.F.R. Part 229 — funds availability schedules, which are not final collection.
Uniform Unclaimed Property Act / Revised Uniform Unclaimed Property Act (2016) — the model escheat regime, adopted in varying forms by the states.

Accuracy notes. IOLTA programs are creatures of state supreme court rules: participation requirements, eligible institutions, interest remittance, comparability rules, and recordkeeping obligations all vary. The treatment of flat fees and "nonrefundable" retainers varies sharply by jurisdiction — some require trust deposit until earned; others permit operating-account deposit with written disclosures and conditions. Retention periods, random-audit programs, and registration requirements are likewise state-set and change. Verify current requirements in your own jurisdiction before structuring a fee or relying on any figure or period stated here.
