This checklist resolves a boundary or encroachment dispute in eight phases, beginning with the survey that converts an argument into a fact and ending with a recorded instrument that binds every future owner. Phase 1 identifies which of the four neighbor-law questions is actually presented, because the four have entirely different answers, and Phase 2 assembles the record — deed, title exceptions, plat, prior surveys, and the aerial photograph series that establishes when a fence or structure appeared. Phase 3 orders and reads a boundary survey, including the monument analysis that decides contested lines, and Phase 4 computes any adverse possession or prescription exposure and stops an accruing claim with a written revocable license. Phases 5 and 6 cover the demand, the appraisal that makes the economics visible, and mediation. Phase 7 covers litigation where it becomes unavoidable, including the relative-hardship analysis that governs whether an encroachment must actually be removed. Phase 8 papers and records the resolution, with the lender-consent step most often missed. Model language for the license, the demand letter, the tree hazard notice, and the boundary line agreement is included, with an authorities table and a ranked list of failure modes.

Resolving a Boundary or Encroachment Dispute: A Practical Checklist

Two documents resolve most of these disputes: a survey, which converts an argument into a fact, and a one-sentence written license, which stops a prescriptive right from accruing. Both cost less than a single deposition, and both are almost always skipped.

How to use this checklist

Phases run in order. Under each are - [ ] items and a Why it matters, and the traps note. A running hypothetical — Hattie Lindqvist (fictional), whose neighbor's new garage may cross the line and whose corner has been driven over for eleven years — makes it concrete.

Doctrine is in Neighbor Law: A Comprehensive Guide to Boundaries, Easements, Nuisance, and Adverse Possession. The narrative introduction is Good Fences: The Law of Boundaries, Trees, Noise, and the Neighbor Who Will Not Stop. The resource map is The Neighbor and Boundary Dispute Toolkit.

Phase 1 — Identify which question this actually is

  • [ ] Where is the line? — a survey question.
  • [ ] Who has acquired rights across it? — adverse possession, prescription, or acquiescence.
  • [ ] What may each owner do on their own land? — nuisance, trees, water, support.
  • [ ] What remedy will a court grant? — damages, injunction, or a payment for a permanent invasion.
  • [ ] Separate the grievances; most disputes contain three or four unrelated ones.
  • [ ] Identify which grievance, if any, has a running clock.
  • [ ] Identify which are governed by ordinance or covenant rather than by common law.

Why it matters, and the traps. Neighbors arrive with a list. The items on it are usually governed by entirely different law, have entirely different odds, and require entirely different responses. Sorting them takes twenty minutes and prevents months of misdirected effort.

The clock question is the urgent one. Adverse use accruing toward a prescriptive right is the only item on a typical list that gets worse by waiting.

Worked example. Hattie's list: a possibly encroaching garage (question one, then four); a driveway apron used for eleven years (question two — urgent); trees blocking light (question three, and probably no claim); and a Saturday leaf blower (ordinance, not litigation).

Phase 2 — Assemble the record

  • [ ] Obtain the deed and every deed in the chain for at least the statutory period.
  • [ ] Obtain the title commitment or policy and read the exceptions — easements and encroachment notes live there.
  • [ ] Obtain the recorded plat and any prior surveys.
  • [ ] Search the county records for easements, boundary agreements, and covenants.
  • [ ] Obtain the tax map and assessor's parcel data.
  • [ ] Obtain an aerial photograph series — many jurisdictions have imagery going back decades.
  • [ ] Photograph the current condition with dates and reference points.
  • [ ] Identify prior owners who may testify about when a fence or structure appeared.

Why it matters, and the traps. The title commitment's exception schedule is the most under-read document in residential real estate, and it frequently contains the recorded easement that answers the whole dispute.

Aerial imagery is the quiet star of these cases. A dated series showing a fence appearing between the 1998 and 2003 flights establishes the start of a possession period more persuasively than any witness, and it is often available free from a state or county GIS portal.

Phase 3 — Order and read the survey

  • [ ] Retain a licensed surveyor for a boundary survey — not a mortgage inspection, not a plat.
  • [ ] Request that the survey show monuments found and set, improvements, and encroachments.
  • [ ] Request the surveyor's field notes and monument analysis, not just the plat.
  • [ ] Ask specifically how any gap, overlap, or excess in the subdivision was apportioned.
  • [ ] Ask whether any monument was rejected, and why.
  • [ ] Walk the property with the surveyor if possible.
  • [ ] Provide the surveyor with the deeds, prior surveys, and adjoining descriptions.

Why it matters, and the traps. Where two surveys conflict, the disagreement is almost always about which monument controls or how excess was distributed — a legal question layered on a technical one. The party who can explain the reasoning wins; the party holding only a plat cannot.

Recall the priority of conflicting calls: natural monuments, then artificial monuments, then adjoiners, then courses, then distances, then area. A bearing recorded by an 1893 compass yields to the oak both parties stood under.

Worked example. The survey shows the garage slab crossing by nine inches and confirms the driveway apron crosses by four feet at the corner.

Phase 4 — Compute and stop the clock

  • [ ] Determine the adverse possession period in this state, and any tax-payment or color-of-title requirement.
  • [ ] Determine the prescriptive easement period.
  • [ ] Establish when the adverse use or possession began, using the aerial series and prior owners.
  • [ ] Determine whether any period of permission existed — and whether it can be proved.
  • [ ] Assess tacking: was there privity between successive users?
  • [ ] Assess acquiescence and agreement doctrines as easier alternatives for either side.
  • [ ] If a claim is accruing, send a written revocable license immediately.
  • [ ] Consider a formal written objection or, in some states, a recorded notice interrupting prescription.

Why it matters, and the traps. Permission defeats prescription absolutely, and a one-sentence letter converts adverse use into permissive use going forward. This is the highest-value, lowest-cost act in the entire checklist and it is almost never taken, because the owner is focused on the visible new structure rather than the invisible accruing right.

Note the distinction that decides these cases: adverse possession transfers title; prescription transfers only a right to use. A neighbor with a prescriptive right to drive across a corner does not own it, does not pay its taxes, and cannot build on it.

Beware the opposite trap: an offer to buy the strip is evidence against hostility and can defeat the offeror's own adverse possession claim, as Van Valkenburgh v. Lutz, 106 N.E.2d 28 (N.Y. 1952) illustrates. Sequence any purchase offer after, not before, the claim analysis.

Phase 5 — Demand and negotiate

  • [ ] Send a short, factual, non-accusatory letter enclosing the survey.
  • [ ] State what you want, specifically, and offer at least one alternative.
  • [ ] Propose a recorded resolution: boundary line agreement, easement, lot line adjustment, or conveyance at fair value.
  • [ ] Avoid characterizations, threats you will not carry out, and history.
  • [ ] Set a reasonable response date.
  • [ ] Keep the letter in a form you would be content to have read aloud in court.

Why it matters, and the traps. A survey enclosed with a calm letter resolves a substantial fraction of these disputes outright, because most boundary arguments are genuine misunderstandings and both parties are frequently wrong. A survey enclosed with an angry letter resolves almost none, because it converts a factual question into a status contest.

For the craft, see Writing an Effective Demand Letter: A Practical Checklist and Drafting an Effective Demand Letter: The Basics.

Phase 6 — Price it, then mediate

  • [ ] Obtain an appraisal of the disputed strip and of any diminution in value.
  • [ ] Estimate the full cost of litigating: two surveyors, possibly an engineer, an appraiser, and trial.
  • [ ] Compare the two numbers, in writing, with the client.
  • [ ] Consider an offer of judgment or equivalent state procedure to shift post-offer costs.
  • [ ] Propose mediation; many courts require it for these cases.
  • [ ] Prepare for mediation with the survey, the appraisal, and a drafted settlement instrument.

Why it matters, and the traps. Retain the appraiser before the litigation experts. A strip worth $6,000 does not justify $60,000 of expert testimony, and knowing that early is the most valuable service available in this field.

These cases settle at high rates once both sides hold a survey and an appraisal, because at that point the only remaining variable is who pays whom. See Preparing for and Attending a Mediation: A Practical Checklist.

Phase 7 — Litigate, if necessary

  • [ ] Select the claim: quiet title, ejectment, trespass, nuisance, declaratory judgment, or a combination.
  • [ ] Plead the statutory period and each element with dates.
  • [ ] Anticipate relative hardship and be prepared with a damages or conveyance alternative.
  • [ ] Consider a lis pendens where title is at issue and the jurisdiction permits it.
  • [ ] Prepare the surveyor as an expert, including the monument analysis.
  • [ ] Assemble the aerial series, dated photographs, tax and utility records, and prior-owner testimony.
  • [ ] For nuisance, produce the contemporaneous log and any measurements.
  • [ ] Address the remedy in the prayer with precision — an order to remove, in the alternative damages.

Why it matters, and the traps. Relative hardship decides encroachment cases. Where an encroachment is innocent and minor and removal grossly disproportionate, courts commonly award damages or order a conveyance at fair value rather than demolition — the approach reflected in Mannillo v. Gorski, 255 A.2d 258 (N.J. 1969). Clients who cannot accept that outcome spend a great deal to be told it.

For nuisance, remember that adjectives lose and measurement wins: Boomer v. Atlantic Cement Co., 26 N.Y.2d 219 (1970) and Hendricks v. Stalnaker, 380 S.E.2d 198 (W. Va. 1989) both turn on the utility-versus-harm balance, and the party with the log and the readings supplies the court with something to balance.

And remember what is not actionable: light, air, and view, absent covenant, ordinance, or statute — Fontainebleau Hotel Corp. v. Forty-Five Twenty-Five, Inc., 114 So. 2d 357 (Fla. Dist. Ct. App. 1959), with the narrow solar exception of Prah v. Maretti, 321 N.W.2d 182 (Wis. 1982).

Phase 8 — Paper it and record it

  • [ ] Reduce the resolution to a recorded instrument.
  • [ ] Use a survey-grade legal description, never a reference to a fence.
  • [ ] Confirm any lot line adjustment has the required local approval.
  • [ ] Address maintenance, cost allocation, insurance, and relocation in any easement.
  • [ ] Obtain lender consent where a mortgage encumbers the affected parcel.
  • [ ] Confirm the title company will insure over the resolution.
  • [ ] Record, and give each party a conformed copy.
  • [ ] Do not record a revocable license — recording implies an interest in land.

Why it matters, and the traps. The parties to a neighbor dispute are temporary; the line is not. A judgment never recorded, or an informal understanding between two owners who both eventually move, reopens the same argument in twelve years with new people who know nothing about it.

Lender consent is the step most often missed. An unconsented conveyance of a strip encumbered by a mortgage can trigger a due-on-sale clause or leave the resolution uninsurable.

Model language

A. Revocable license (do not record)

"This letter confirms that you have my permission to [continue to park on / cross / maintain landscaping upon] the portion of my property described as [description or reference to survey]. This permission is personal to you, revocable at any time at my discretion, and creates no easement or other interest in my property. Please confirm your agreement by signing and returning the enclosed copy."

B. Neighbor demand letter

"Enclosed is a boundary survey of [address] prepared by [surveyor], dated [date]. It shows that [the structure / the paved area] extends approximately [distance] onto my property along [location]. I do not assume this was intentional and would prefer to resolve it without lawyers. I would be willing to consider [a boundary line agreement fixing the line where it is / an easement permitting the existing use / conveying the affected strip at its appraised value]. Please let me know by [date] whether any of these is acceptable or whether you would like to propose something else."

C. Tree hazard notice

"The [species] near the shared boundary at [location] appears to be dead or structurally compromised, as shown in the enclosed photographs taken [date]. I am providing this notice so that you are aware of the condition."

D. Boundary line agreement recitals

"The true boundary between the parcels is uncertain by reason of [conflicting calls in the deeds / the absence of original monuments / a long-standing fence in a different location]. The parties desire to fix the boundary with certainty. The parties agree that the boundary is the line described on Exhibit A, prepared by [surveyor], and each party quitclaims to the other any interest in the land lying on the other side of that line."

Failure modes, ranked

  1. Never ordering a survey, and arguing about a line nobody has located.
  2. Relying on a plat or mortgage inspection instead of a boundary survey.
  3. Ignoring an accruing prescriptive right while focusing on a visible new structure.
  4. Failing to send a written revocable license when one sentence would end the exposure.
  5. Offering to buy the strip before analyzing the claim, defeating your own hostility element.
  6. Litigating before appraising, and spending more than the land is worth.
  7. Expecting demolition of an innocent minor encroachment.
  8. Pleading nuisance with adjectives instead of a log and measurements.
  9. Settling without recording, so the dispute reopens for the next owners.
  10. Forgetting lender consent on a conveyance of encumbered land.

Four dispositions, worked

The garage crossing by nine inches

Survey confirms the encroachment. It is innocent, minor, and expensive to remove. Under relative hardship, demolition is unlikely; the realistic outcomes are damages, a conveyance of the strip at appraised value, or a recorded easement.

The right sequence: survey, then appraisal of the strip, then a written proposal offering all three alternatives. The appraisal is what makes the conversation possible — the neighbor who has been told "you must tear down your garage" refuses, while the neighbor told "the strip appraises at $2,400 and I will convey it for that" usually accepts.

The driveway apron used for eleven years

This is the urgent item and the one nobody notices, because it is old and unremarkable while the garage is new and visible. Eleven years may exceed the prescriptive period. A one-paragraph revocable license, delivered by certified mail today, converts the use to permissive and ends the exposure. It costs nothing.

The general rule this illustrates: in neighbor law the new and visible problem is rarely the one with a deadline.

The fence in the wrong place since 1978

Both households have treated it as the line for four decades. The deed disagrees by six feet. Boundary by acquiescence likely controls, and it is easier to prove than adverse possession because hostility is not an element.

The correct outcome is a recorded boundary line agreement conforming the record to the reality — cheaper than either party's expert, and binding on everyone who comes after.

The trees blocking the afternoon light

No claim absent a covenant, ordinance, or spite-fence statute. Check the recorded declaration and the zoning height limit; if neither helps, say so plainly. This is the hardest advice to deliver in the practice and the most important, because a client who spends two years litigating it will be no better off and considerably poorer.

What to do first, in one paragraph

If you read nothing else: order a boundary survey, read the title commitment's exception schedule, and identify whether any adverse use is currently accruing. Those three steps cost a few hundred dollars and a Saturday morning, and they answer or reframe nearly every dispute described in this checklist. Everything after them — the demand letter, the appraisal, the mediation, the recorded agreement — follows naturally from knowing where the line is and who has been doing what across it, for how long. Everything before them is argument without facts, which is the most expensive form of legal work there is.
