A client sat in my office last month, head in his hands. His mother had passed, leaving a will that seemed clear. She had named him executor and divided her assets between her three children. But now, his estranged sister was threatening a lawsuit, claiming their mother wasn’t “in her right mind” when she signed it. The estate—including the family home in Brooklyn—was frozen. The inheritance was on hold. The family was fracturing.
This is a scene I have witnessed countless times. Many people believe that once a will is signed, the matter is settled. But a will is not self-executing. It is a set of instructions that a judge in Surrogate’s Court must validate through a process called probate. During this process, simmering family tensions often boil over into open conflict, turning a private family matter into a public legal battle.
The court’s role is to ensure the will is authentic, that it was created without coercion, and that it meets all legal formalities required by New York law. This process is meant to protect the decedent’s final wishes. But it also creates an opportunity for a dissatisfied heir to object and bring everything to a halt.
Grounds for a Will Contest
When someone challenges a will, they cannot simply state that they dislike its terms. The law requires specific legal grounds to invalidate a will. In my practice, the challenges almost always fall into one of four categories.
The most common is a claim of undue influence. This happens when a person in a position of trust—often a child, a new spouse, or a caregiver—exerts so much pressure on the testator that the will reflects the influencer’s desires, not the testator’s. This is more than giving advice. It is a form of coercion that strips the testator of their free will. Proving it is difficult, as it often happens behind closed doors, but it is a frequent allegation when one beneficiary receives a surprisingly large share of the estate.
Another common challenge is lack of testamentary capacity. The person signing the will must be of sound mind. New York law requires that they understand they are signing a will, know the general nature and extent of their property, and know who their natural heirs are. A diagnosis of dementia or another cognitive impairment does not automatically invalidate a will, but it does open the door for a challenge.
We also see challenges based on improper execution. New York has very strict rules for how a will must be signed and witnessed. Under Estates, Powers and Trusts Law (EPTL) § 3-2.1, the testator must sign the will in the presence of two witnesses, who must also sign their names within a 30-day period. If any of these technical steps are missed—the witnesses are not in the room, the testator does not declare it is their will, or the signatures are out of order—the entire document can be thrown out.
Finally, there are claims of fraud or forgery. This is an allegation that the signature on the will is fake or that the testator was tricked into signing a document they believed was something else entirely. These cases are less common, but they are serious and require substantial evidence to prove.
The True Cost of a Probate Fight
A will contest is not just a legal procedure. It is a declaration of war on a family’s legacy. The financial costs are the most obvious. Litigation is expensive. Attorney fees, expert witness costs, and court filings are paid from the estate’s assets. I have seen modest estates nearly exhausted by years of legal fighting, leaving little for anyone, including the victor.
But the emotional cost is often higher. Siblings stop speaking. Reputations are damaged as personal medical records and private family conflicts become part of the public record in Surrogate’s Court. The process forces family members into adversarial roles, formalizing resentments that may never heal. The decedent’s intention—to provide for their loved ones—is lost in the crossfire.
Prudent estate planning anticipates these potential conflicts. It is more than drafting a document. It requires a deep understanding of family dynamics and the strategic use of legal instruments—like trusts—that can bypass the probate process altogether.
Stewardship Beyond the Document
A will contest is a failure of stewardship. It means something in the planning process, or in the family relationships, went wrong. No plan is immune to a legal challenge from a determined heir, but a deliberate and well-documented planning process creates a formidable defense.
This includes ensuring the signing ceremony is conducted with precision, documenting the testator’s mental state, and perhaps explaining to family members ahead of time what the plan contains and why. It is about building a legacy that can withstand not just the passage of time, but the pressures of human nature.
If you are an executor facing a potential will contest, or a beneficiary who believes a will is the product of coercion or fraud, the first step is an objective assessment. We provide a confidential case review to analyze the will and the facts surrounding its creation to determine if the grounds for a challenge meet the high standards of proof required by New York law.
