How to Resolve House Disputes in New York: A Decision Framework for Choosing the Right Legal Action

Reviewed by Albert Goodwin, Esq., New York estate and real property litigation attorney, Law Offices of Albert Goodwin. Last reviewed: June 2024. This article is general legal information, not legal advice for your specific situation.

Disputes over a house in New York rarely fail because the facts are hopeless. They fail because the wrong legal action gets filed, the wrong statute of limitations runs out, or a party pays for years of litigation when a strategic motion would have ended the fight in months. The hardest part of a house dispute is not knowing whether you have a claim — it is knowing which claim, in which New York court, under which statute, and what it realistically costs and takes.

This page is the decision map. Rather than re-explaining each topic (we cover those in depth on the dedicated pages linked below), this guide synthesizes how a New York attorney actually chooses the right remedy. Use the framework to identify your situation, then follow the link to the in-depth analysis.

Step One: Identify the Relationship Behind the Dispute

Almost every house dispute in New York falls into one of four relationships, and the relationship dictates the court, the statute, and the available remedies:

• Co-owners (including heirs who inherited together) → partition under RPAPL Article 9, in Supreme Court.
• Estate beneficiaries vs. a fiduciary or a transfer made before death → will or deed contest under the EPTL/SCPA, in Surrogate's Court.
• Landlord and tenant → summary proceeding under RPAPL Article 7, in the local landlord-tenant or housing court.
• Lender and borrower, or buyer and seller → foreclosure under RPAPL Article 13 or breach of a real-estate contract, in Supreme Court.

Misidentifying the relationship is the most common, and most expensive, mistake. An heir who tries to "evict" a sibling living in an inherited house, for example, usually cannot bring a landlord-tenant proceeding at all, because no landlord-tenant relationship exists between co-owners. The correct vehicle is partition, sometimes combined with a Surrogate's Court turnover proceeding.

The New York Dispute-to-Remedy Framework

The table below summarizes how each common house dispute maps to a remedy, the governing New York statute, the court, and a realistic timeline. Timelines and costs vary widely by county and by how hard the other side fights; these are typical ranges, not promises.

Disputes Among Family Members and Heirs

Family house disputes split into two situations, and they are governed by entirely different statutes.

When Heirs Co-Own the House Together

When someone dies without a will (intestate), New York's EPTL 4-1.1 distributes real property to the heirs as tenants in common — for example, the children inherit in equal shares. The same co-ownership arises when a will leaves the house to several beneficiaries jointly. The recurring conflict: one heir lives in the property and pays nothing, while the others get no benefit and cannot force a sale.

The remedy is a partition action under RPAPL Article 9. New York courts strongly prefer partition by sale when the property is a single-family home that cannot be physically divided (RPAPL 915), and physical division is usually reserved for raw or large parcels. A well-pleaded partition complaint also lets the court order an accounting (RPAPL 945), so a co-owner who paid taxes, insurance, the mortgage, or capital repairs can be credited from the sale proceeds, and a co-owner who occupied the property exclusively can sometimes be charged the reasonable rental value. That accounting leverage — not just the threat of a sale — is what usually drives settlement. See our deep-dive pages on partition of property in New York, the brother living rent-free in an inherited house, the beneficiary living in the estate's house, and the sibling who refuses to leave a deceased parent's house.

When One Family Member Became Sole Owner

The second family scenario is a transfer that cut other heirs out entirely. How you challenge it depends on whether the transfer happened before or after death.

A deed signed before death. If a parent deeded the house to one child (often reserving a life estate), the other family members may sue to set aside the deed for lack of capacity, undue influence, fraud, mistake, or forgery. The key burden is intent: a deed will not be undone simply because the gift was unfair. You must show a genuine defect in the parent's intent or the execution. The deadline matters — a general action to set aside a conveyance is governed by the six-year period in CPLR 213, and a fraud-based claim runs the longer of six years from the act or two years from when the fraud could reasonably have been discovered (CPLR 203(g)). Read our detailed page on contesting a deed transfer in New York.

A gift made in the will. If the house passed under a will, the vehicle is a will contest in Surrogate's Court — formally, objections to probate after SCPA 1404 examinations of the attorney-drafter and attesting witnesses. The grounds are due execution (EPTL 3-2.1), testamentary capacity, undue influence, fraud, and forgery. Unlike a deed, you generally cannot void a will for innocent mistake unless the mistake resulted from fraud. If the will is denied probate, the house passes under any prior valid will or, if none, by intestacy under EPTL 4-1.1. See how to contest a will in New York and our inheritance dispute attorney page.

If a fiduciary is mismanaging or hiding estate property, the related tools are a discovery and turnover proceeding under SCPA 2103/2104 and a breach of fiduciary duty claim.

Disputes Among Co-Owners Who Bought Together

Unrelated co-owners — business partners, unmarried couples, friends pooling funds — face the same partition remedy as heirs, but their disputes are far better prevented than litigated. A co-ownership (tenancy-in-common) agreement signed at purchase can fix in advance the issues that otherwise become lawsuits: capital contributions, ownership percentages, who pays the mortgage, taxes, and repairs, what happens when one owner can't pay, buyout rights and how the price is set, rental and profit-sharing rules, dispute resolution, and what happens on an owner's death. Without that agreement, the default is a partition action — and partition is a blunt instrument that can force a sale at a sub-optimal time. An attorney who drafts the agreement up front almost always saves far more than litigation later. See disputes when a house is in two names, offering a buyout of a jointly owned residence, and responding to a buyout offer.

Disputes With a Contractual Counterparty

Landlord and Tenant

A New York landlord cannot self-help — changing locks or removing belongings is illegal and can expose the landlord to treble damages under RPAPL 853. The lawful path is a summary proceeding under RPAPL Article 7: a nonpayment proceeding for unpaid rent or a holdover proceeding when the tenancy has ended or the lease was violated. These cases are intensely procedural — a defective rent demand, predicate notice, or pleading can get the whole case dismissed, especially under the heightened notice requirements of the Housing Stability and Tenant Protection Act of 2019. Tenants, in turn, have claims for unreturned security deposits (capped and regulated under General Obligations Law 7-108), rent overcharge, and warranty-of-habitability violations (RPL 235-b). We address both sides on our attorney for landlords and tenant rights pages.

Lender and Borrower (Foreclosure)

A correction worth stating plainly, because it confuses many homeowners: the mortgagor is the borrower (the homeowner) and the mortgagee is the lender. When a homeowner stops paying, the lender — the mortgagee — initiates a foreclosure against the borrower (mortgagor) under RPAPL Article 13. New York is a judicial-foreclosure state, so the lender must sue and win in Supreme Court before any sale. That gives the homeowner real defenses: standing (did the plaintiff actually hold the note when it sued), compliance with the strict 90-day pre-foreclosure notice in RPAPL 1304, the contractual default notice, and the mandatory settlement conference under CPLR 3408. Procedural defects in these requirements routinely delay or defeat foreclosures. See how long a foreclosure takes in New York.

Notice of Pendency (Lis Pendens)

Any lawsuit that affects title to or possession of real property — partition, foreclosure, specific performance — usually triggers a notice of pendency under CPLR 6501, recorded against the property to warn buyers that litigation is pending. It effectively freezes a clean sale. The good news: a notice of pendency can be cancelled under CPLR 6514 if it was improperly filed, if the underlying action does not actually affect title, or if the plaintiff failed to comply with the rules, and the court can award costs and expenses for an improper filing. See our notice of pendency attorney page.

Buyer and Seller

When a real-estate deal falls apart, the fight is usually over the contract deposit. New York's Statute of Frauds (General Obligations Law 5-703) requires contracts for the sale of real property to be in writing, and whether the deposit is returned turns on the contract's contingencies (mortgage, inspection, title), which party breached, and whether time was made "of the essence." A non-breaching seller may be entitled to keep the deposit as liquidated damages, or a buyer may be able to compel the sale through specific performance. Before sending a notice of cancellation or demanding a deposit back, have a lawyer read the actual contract — acting on a contingency that has lapsed can flip you from the innocent party into the breaching one.

Disputes With Unrelated Parties — Neighbors and Boundaries

Boundary and encroachment fights between neighbors are resolved through a quiet-title action under RPAPL Article 15, often combined with claims of adverse possession (RPAPL 501–551) or disputes over easements. New York tightened adverse-possession law in 2008, so a claim now generally requires hostile, open, and continuous possession for ten years, and a good-faith requirement and a narrow view of "de minimis" encroachments now apply. Easements — including prescriptive and right-of-way easements — can be created and also terminated (by merger, release, abandonment, end of necessity, or condemnation). Because a wrong move against a neighbor can itself create liability, survey and title review come before any self-help. See adverse possession in New York and how easements work in New York.

An Attorney's Perspective: How We Choose the Right Action

When a client describes a house dispute, the first questions are not about who is right — they are about leverage and procedure:

• What is the deadline? A will contest waits for probate; a deed challenge runs on CPLR 213/203(g); a foreclosure defense lives or dies on RPAPL 1304 notices. Missing a statute of limitations forfeits an otherwise winning case.
• Which court? Surrogate's Court for estate and probate matters; Supreme Court for partition, foreclosure, and quiet title; housing court for landlord-tenant. Filing in the wrong court costs months.
• What is the realistic endgame? Most partition and inheritance disputes settle, because a forced sale and shared legal fees hurt everyone. The lawsuit's purpose is often to create credible leverage — an accounting credit, a notice of pendency, a strong objection — that brings the other side to the table.
• What is it going to cost? Litigation fees can come out of the very asset being fought over (sale proceeds, the estate). Sometimes a negotiated buyout drafted in a week is worth more than a "win" two years and tens of thousands of dollars later.
