Estate litigation in New York is the process by which family members, beneficiaries, and other interested parties resolve disagreements about a deceased person’s estate in the Surrogate’s Court of the county where that person lived. These disputes most often arise over whether a will is valid, how an estate should be administered, who is entitled to inherit, and whether a fiduciary has mishandled assets. When heirs cannot agree, the Surrogate’s Court — applying the Estates, Powers and Trusts Law (EPTL) and the Surrogate’s Court Procedure Act (SCPA) — becomes the forum that decides who is right.
I have sat across the table from siblings who hadn’t spoken in years and from a surviving spouse who learned, only after the funeral, that she had been written out of a will signed weeks before death. Few areas of law are as emotionally charged. Money is rarely the only thing in play; old grievances, perceived favoritism, and grief all show up in the courtroom. This guide explains, in plain terms, how these conflicts unfold in New York and what your options are.
Where heir disputes get decided: New York’s Surrogate’s Court
Every county in New York has a Surrogate’s Court, and that is where probate and estate administration happen. If the decedent left a will, the named executor files a petition to admit it to probate. If there is no will, a relative petitions for letters of administration, and the estate passes by intestacy under EPTL 4-1.1, which sets the order — spouse and children first, then more distant relatives.
Disputes can surface at almost any stage. They tend to fall into a handful of recognizable categories, and knowing which one you’re dealing with shapes everything that follows.
- Will contests — challenges to the validity of the document itself.
- Spousal right of election claims — a surviving spouse asserting a statutory minimum share.
- Kinship and status disputes — fights over who actually qualifies as an heir.
- Fiduciary misconduct — claims that an executor, administrator, or trustee breached their duties.
- Construction proceedings — disagreements over what ambiguous will language means.
Will contests: the most common — and most contentious — fight
A will contest is a formal objection to admitting a will to probate. Only an “interested party” — generally someone who would inherit more if the will were rejected — has standing to object. Before filing objections, that person is usually entitled to conduct discovery under SCPA 1404, which allows examination of the attorney who drafted the will and the witnesses who watched it get signed. That examination is the single most important fact-gathering step in any contest, and it happens before objections are even filed.
New York recognizes four primary grounds for invalidating a will. They often overlap in a single case.
1. Lack of testamentary capacity
The person making the will (the testator) must understand, at the moment of signing, the general nature and extent of their property, the people who would naturally inherit from them, and the fact that they are signing a will that distributes that property. The standard is not high — someone with mild dementia can still have a lucid interval — but a documented diagnosis, hospital records, or testimony about confusion near the signing date can carry real weight.
2. Undue influence
This is the claim I see most in families. Undue influence means someone exerted such pressure on the testator that the will reflects the influencer’s wishes rather than the testator’s own free choices. Courts look for opportunity, motive, and a suspicious result — for example, a late-in-life caregiver or one child who isolated the parent, controlled access to the lawyer, and ended up with a disproportionate share. Because direct proof is rare, these cases are usually built on circumstantial evidence.
3. Improper execution
EPTL 3-2.1 sets strict formalities: the will must be signed at the end by the testator, that signing (or acknowledgment of it) must occur in the presence of at least two witnesses, and the witnesses must sign within thirty days of one another. A will that ignores these rules can fail no matter how clearly it states the testator’s intent.
4. Fraud and forgery
Less common but serious — a forged signature, or a will procured by lies told to the testator about the beneficiaries.
One practical caution: many New York wills contain an in terrorem (no-contest) clause that disinherits a beneficiary who challenges the will. EPTL 3-3.5 governs these clauses and carves out important safe harbors, including the SCPA 1404 examinations, so beneficiaries can investigate without automatically forfeiting their gift. Anyone weighing a contest should understand exactly how that clause applies before making a move. For a deeper look at the mechanics, Morgan Legal’s New York team explains in useful detail.
The surviving spouse’s right of election
New York does not let a person fully disinherit a spouse. Under EPTL 5-1.1-A, a surviving spouse has a right of election to claim the greater of $50,000 or one-third of the net estate, regardless of what the will says. Critically, the elective share reaches beyond the probate estate — it captures certain “testamentary substitutes” such as jointly held property, Totten trust bank accounts, and assets the decedent gave away or transferred late in life to dodge the spouse’s claim.
The deadline is unforgiving. The election generally must be filed within six months after letters are issued, and no later than two years after death. Miss it, and the right is usually gone. I have seen surviving spouses lose six-figure entitlements simply because no one told them the clock was running. If you are a surviving spouse who feels shortchanged by a will, this is the first deadline to calendar.
Disputes when there is no will, and kinship fights
When someone dies intestate, EPTL 4-1.1 dictates the distribution, but the conflict often shifts to who counts as an heir. Kinship proceedings — in which claimants must prove their family relationship to the decedent — can become extraordinarily complex in estates with no close survivors, especially where there are half-siblings, non-marital children, or relatives spread across countries. The burden is on the claimant to prove the relationship, and the court may appoint a guardian ad litem to protect unknown heirs.
For modest estates, New York offers a streamlined path. Under SCPA Article 13, voluntary administration (the “small estate” procedure) is available when the decedent left personal property worth $50,000 or less, excluding certain exempt items. It is faster and cheaper than full administration — but it does not eliminate disputes, and using it does not bar a later challenge if real assets or a hidden will surface.
Fiduciary misconduct: when the executor is the problem
Sometimes the will is valid and the heirs are settled, yet the fight is just beginning — because the person in charge is mismanaging the estate. Executors, administrators, and trustees are fiduciaries. They owe duties of loyalty, prudence, and impartiality, and they must account for every dollar.
Beneficiaries who suspect misconduct have real tools:
- Petition to compel an accounting under SCPA 2205, forcing the fiduciary to lay out every receipt and disbursement.
- File objections to that accounting, challenging specific transactions — self-dealing, unexplained withdrawals, unsold property, or excessive fees.
- Seek removal or suspension of the fiduciary under SCPA 711 and 719 where there is dishonesty, waste, or a disqualifying conflict.
- Pursue a surcharge, making the fiduciary personally repay losses caused by their breach.
A common flashpoint is the fiduciary who is also a beneficiary — the sibling-executor who lives in the family house rent-free, drags out the sale, and stops returning calls. Delay itself can be a breach. New York Surrogates expect estates to move forward, and an accounting proceeding is often the lever that gets things unstuck.
Lifetime documents that shape — and sometimes spark — disputes
Many estate fights are seeded years before death by the documents a person signs while alive. A New York statutory durable power of attorney under General Obligations Law 5-1501 lets an agent manage the principal’s finances, and abuse of that authority — gifts to the agent, drained accounts, transferred property — is one of the most litigated issues in estate cases. The 2021 overhaul of the form tightened execution requirements and added a statutory damages remedy against third parties who wrongly reject a valid POA.
A health care proxy governs medical decisions, not money, but disagreements among family members about end-of-life care frequently bleed into the later estate dispute. And a revocable living trust, while it avoids probate for the assets it holds, does not avoid litigation: the same grounds — capacity, undue influence — that void a will can void a trust amendment, and a trustee owes the same fiduciary duties as an executor.
If you’re trying to prevent these problems rather than litigate them, careful drafting matters enormously. You can review our overview of wills and estate planning and the general probate process to understand how the pieces fit together.
How New York estate disputes actually get resolved
Despite the dramatic reputation, most estate disputes settle. A full will-contest trial is expensive, slow, and unpredictable, and the asset being fought over shrinks with every legal bill. The realistic resolution paths are:
- Negotiated settlement — a renegotiation of shares, memorialized in a written agreement and approved by the court.
- Mediation — increasingly common and often court-encouraged, with a neutral helping families reach a deal that preserves whatever relationships remain.
- Motion practice — many contests end on summary judgment when the objectant cannot produce enough evidence on capacity or undue influence to reach trial.
- Trial in Surrogate’s Court — the last resort, sometimes before a jury on a will contest.
The strength of your position usually turns on evidence gathered early: medical records, the drafting attorney’s file, the SCPA 1404 testimony, bank statements, and the pattern of who controlled access to the decedent. Cases are won and lost in the first few months, long before any trial. Morgan Legal’s discussion of is a good companion read for families just entering this. For relatives dealing with a Florida estate connected to a New York family, an affiliated office handles Florida probate matters as well.
When to bring in a New York estate litigation attorney
Call a lawyer before you file objections, before you sign a waiver and consent, and certainly before any deadline like the six-month elective-share window passes. The most painful cases I handle are the ones where someone waited — signed away rights they didn’t understand, missed a filing date, or let a year of fiduciary misconduct go unchallenged. Early advice is cheap compared to a contested trial, and it often points toward a resolution that keeps the family, and the estate, intact.

Frequently asked questions
How long do I have to contest a will in New York?
There is no single fixed statute of limitations, but you must act before the will is admitted to probate and a decree is issued. Once you receive a probate citation, you have a short window to appear and object, and once a probate decree is final it becomes very difficult to undo. Practically, you should consult an attorney the moment you learn a will exists and disagree with it.
Can I be disinherited entirely in New York?
A spouse cannot be fully disinherited because of the right of election under EPTL 5-1.1-A, which guarantees the greater of $50,000 or one-third of the net estate. Adult children, by contrast, can be disinherited — New York does not give children a forced share — though a disinherited child may still have standing to contest the will on grounds like undue influence or lack of capacity.
What does it cost to litigate an estate dispute?
It varies widely with complexity and how early the case settles. Many disputes resolve through negotiation or mediation at a fraction of trial cost. Note that an estate cannot generally be made to pay your personal legal fees for an unsuccessful contest, so the economics of any challenge should be weighed honestly at the outset.
What if the executor won’t communicate or distribute the estate?
You can petition the Surrogate’s Court to compel an accounting under SCPA 2205, and if there is misconduct, waste, or a conflict, you can seek the fiduciary’s removal under SCPA 711 and 719. Unreasonable delay alone can justify court intervention.
Does a living trust avoid these disputes?
A revocable living trust avoids the probate process for the assets it holds, but it does not make the estate dispute-proof. A trust amendment can be challenged for lack of capacity or undue influence just like a will, and a trustee owes the same fiduciary duties an executor does.
