A few years ago, a man walked into my office and placed a stained cocktail napkin on my desk. On it, in shaky handwriting, were a few sentences signed by his recently deceased father, a long-time restaurant owner in Queens. It purported to leave the entire business to him, cutting out his sister completely. The son’s question was simple: “Is this a valid will?”
The legal question, however, was far more complex. It wasn’t about the napkin—it was about his father. Was he, in the eyes of the New York Surrogate’s Court, a legally valid testator at the moment he wrote it? This is the foundational question of all estate planning. The entire authority of a will flows from the person who creates it: the testator.
Who Is the Testator?
A common misunderstanding is that a testator is a role you assign, like an executor or a trustee. This is incorrect. If you are the one creating and signing the will, you are the testator. It is your voice, your intent, and your authority that gives the document its power. You are not choosing a testator; you are the testator.
Being a testator is not merely about signing a piece of paper. It is an act of profound legal significance. You are directing the stewardship of your life’s work and providing for the next generation. Because this act is so final, the law sets a specific threshold you must meet. This threshold is not about your intelligence, your business acumen, or your grammar. It is about a specific legal concept: testamentary capacity.
The Standard for a Testator in New York
New York law is clear on who can make a will. According to Estates, Powers and Trusts Law (EPTL) §3-1.1, any person 18 years of age or older and of “sound mind and memory” can create a will. That phrase—“sound mind and memory”—is where most will contests are fought.
It doesn’t mean you need a perfect memory. It doesn’t mean you must be in perfect health. In my practice, I have assisted clients with early-stage dementia and serious physical illnesses in creating perfectly valid wills. The standard, as interpreted by our courts, is specific to the act of making the will itself. At the moment of execution, a testator must generally understand three things:
- The nature and extent of their property—what they own.
- The natural objects of their bounty—who their closest family members are.
- The nature of the disposition they are making—that they are signing a will that will distribute their property after their death.
When a will is properly executed with an attorney, the signing ceremony itself helps create a presumption of capacity. The two witnesses required by law are not just observing a signature. They are attesting that they believe the testator is of sound mind and acting of their own free will. This is why a professionally supervised execution is so much more durable than a signature on a cocktail napkin.
Freedom of Disposition—With Limits
As the testator, you have immense freedom to distribute your assets as you see fit. You can leave your property to family, friends, or a charity. You can also be intentional about disinheriting someone, provided it is done with clarity. This is your legacy, and the law respects your right to direct it.
However, this freedom is not absolute. New York law places certain guardrails to protect against outcomes that public policy deems unfair. The most significant of these is the spousal right of election. You generally cannot completely disinherit your spouse. Under EPTL §5-1.1-A, a surviving spouse has the right to claim an “elective share” of the decedent’s estate—typically one-third of the net estate—regardless of what the will says. This is a powerful protection designed to prevent a surviving spouse from being left without support.
The testator’s intent must also be free from undue influence, fraud, or duress. A will is only valid if it is a true reflection of the testator’s wishes. If a court finds that a testator was manipulated or coerced by a person in a position of trust—a caregiver, a child, a new acquaintance—the will can be invalidated. This is where clarity, consistency, and a history of deliberate planning become your best defense against a future challenge.
Ensuring Your Intent Is Honored
The story of the cocktail napkin ended in a prolonged and costly court battle. The dispute hinged entirely on proving the father’s capacity and intent at the moment of signing. Was he lucid? Was he being pressured? Was it a serious directive or an offhand note? All of these questions could have been avoided.
A will is more than a document; it is the final expression of your stewardship over your assets and your care for your family. Its validity rests squarely on your shoulders as the testator. Ensuring it is prepared with legal precision and executed under formal supervision transforms it from a piece of paper into a durable instrument of your legacy.
Before you begin this process, it is prudent to organize your own understanding of your assets and your family structure.
