A Brooklyn family buries their father on a Tuesday. By Thursday, they discover he signed a new will just three weeks before his death, leaving his home and his entire brokerage account to a private caregiver he hired in January. The children are stunned, angry, and absolutely convinced their father lacked the mental capacity to understand what he was signing. They want to challenge the document immediately.
But walking into Surrogate’s Court with a profound sense of injustice is not enough. You need standing, you need legal grounds, and you need admissible evidence.
A probate contest is one of the most contentious proceedings in estate law. It pits family members against one another and places the private life of the deceased under a legal microscope. Many people assume an unfair will is inherently invalid. The law disagrees. A competent adult has the absolute right to disinherit their children, leave their wealth to a stranger, or fund a charity. A will is only overturned when we can prove a specific defect in how it was created or the circumstances surrounding its execution.
Who Has the Right to Object?
Before we evaluate the validity of the document itself, we must determine if you have the legal right to challenge it. Under Surrogate’s Court Procedure Act (SCPA) §1410, a person can only file objections to a will if their financial interest in the estate would be adversely affected by its admission to probate.
Standing is a strict mathematical reality. If you are left out of a 2024 will, but you were also intentionally excluded from a 2015 will, you generally do not have standing to object to the newer document. Overturning the 2024 will would simply reinstate the prior instrument, leaving you in the exact same financial position. The court will dismiss your claim. You must show that defeating the current will restores an inheritance you would have otherwise received—either through a prior testamentary instrument or through the laws of intestacy.
Establishing Legal Grounds for a Probate Contest
If standing is established, the focus shifts to the specific legal grounds for the contest. You cannot object simply because the distribution is unequal or surprising. We must build a case around one of four recognized legal theories.
Improper Execution
New York imposes rigid formalities on how a will must be signed. Under EPTL §3-2.1, the testator must sign the document at the end, or direct someone to sign for them in their presence. They must declare to at least two witnesses that the document is their will, and those witnesses must sign within a 30-day period. If a will is drafted by an attorney and the execution is supervised by an attorney, the court applies a presumption of proper execution. However, with the rise of do-it-yourself legal forms, we frequently see fatal execution errors. If the witnesses did not actually see the testator sign, or if the testator never explicitly acknowledged the document as their will, the instrument fails.
Lack of Testamentary Capacity
The mental capacity required to sign a will in New York is surprisingly low—far lower than the capacity required to sign a complex business contract. To possess testamentary capacity, the testator must simply understand three things at the exact moment they sign the document: the general nature and extent of their assets, the natural objects of their bounty, and the practical effect of signing the will.
A medical diagnosis of dementia or Alzheimer’s disease does not automatically invalidate a testamentary instrument. A person suffering from severe cognitive decline can still execute a valid document if they experience a lucid interval at the time of signing. To win on these grounds, we must subpoena medical records, physician notes, and witness testimony to prove the testator’s mind was too compromised to understand the transaction on that specific day.
Undue Influence
This is the most common allegation in a probate contest—and one of the most difficult to prove. Undue influence is not merely begging, nagging, or threatening. It requires a showing of moral coercion that destroys the free agency of the testator, substituting the will of the influencer for the true wishes of the deceased.
Because undue influence happens behind closed doors, direct evidence is rare. We build these cases on circumstantial evidence. We look for sudden changes in estate planning shortly after a new person isolates the testator from their family. We examine who contacted the drafting attorney, who drove the testator to the law office, and who sat in the room while the document was signed.
Fraud
A will is invalid if it is procured through fraud. This typically takes two forms. Fraud in the execution occurs when someone tricks the testator into signing a document by lying about its nature—for instance, telling an elderly parent they are signing a routine tax form when it is actually a new will. Fraud in the inducement occurs when someone lies to the testator about a material fact, causing them to change their will based on that false information. An example would be one sibling falsely convincing a parent that another sibling has stolen money from their accounts.
The Discovery Process: SCPA 1404 Examinations
Clients often ask how quickly a probate contest can be resolved. The honest answer?
Years.
Estate litigation requires extreme patience. It is a deliberate, methodical process designed to uncover facts that someone went to great lengths to hide.
Before formal objections are even filed, New York law provides a powerful discovery tool. Under SCPA §1404, interested parties have the right to examine the drafting attorney and the attesting witnesses under oath. We can compel the production of the drafting attorney’s file, including their handwritten notes, emails, and billing records.
This preliminary examination is critical. It allows us to depose the individuals involved in the execution ceremony without triggering a no-contest clause, should one exist in the document. A rigorous 1404 examination often dictates whether a family proceeds with a full probate contest or decides to negotiate a settlement.
A probate contest fractures families and drains estate assets, but it is sometimes the only mechanism available to protect a loved one’s true legacy from manipulation. If you suspect a recently filed will was procured through undue influence or a lack of capacity, time is severely limited. I encourage you to schedule a formal review of the probate petition and the accompanying will with our office so we can determine if you have standing and viable grounds to object.
