Testamentary Capacity Disputes
Testamentary capacity is the mental ability the law requires of a person signing a will. The person must understand, at the time of signing, that the document disposes of property at death, must know in general terms what property they own, and must know who their family and natural heirs are and how the will treats them. A will signed by a person who lacked that understanding is invalid, and the estate passes under an earlier will or under the state’s intestacy rules.
The standard is lower than most people expect. It asks less of the signer than a contract or a deed does, it is measured at the moment of signing rather than over the course of an illness, and a diagnosis of dementia, a stay in a nursing home, or a guardianship does not by itself defeat a will. A person with significant impairment can sign a valid will during a lucid period, and a person with no diagnosis at all can lack capacity on a particular day because of medication, delirium, or the effects of a stroke. That is why capacity cases are decided on evidence about the signer’s condition on the day, not on labels.
Milvidskiy Law Group P.C. brings and defends capacity challenges to wills, trusts, deeds, and other documents. Our attorneys also supervise signings for clients whose capacity may later be questioned, and that experience shapes how we evaluate a challenged document.
Key Takeaways:
- Testamentary capacity requires that the signer understand the nature of a will, the general extent of their property, and the natural objects of their bounty, at the time of signing. The test is the same in substance in New York, New Jersey, and Connecticut, and each state requires the signer to be at least eighteen and of sound mind.
- Capacity is judged at the moment of signing. A diagnosis, a guardianship, or confusion on other days is evidence, not proof. A will signed during a lucid interval can be valid.
- The case is won or lost on the records and witnesses closest to the signing: the drafting attorney’s file, the attesting witnesses, the medical chart for the surrounding weeks, and, where one was obtained, a contemporaneous capacity evaluation.
The Legal Standard
All three of our states permit any person eighteen or older who is of sound mind to make a will. Courts have given “sound mind” a specific meaning in this context. The signer must be able to understand three things: that the document is a will that disposes of property at death, the nature and approximate extent of the property being disposed of, and the identity of the people who would naturally be expected to inherit and the way the will affects them. The signer does not need to know the exact value of every account or to make a plan that others consider wise. Eccentricity, old age, physical frailty, forgetfulness, and even a poor decision are not the same as incapacity.
Because the standard is modest, most challenges fail if the signer could hold a coherent conversation about family and property on the day of signing. Most challenges succeed only where the records show the signer was disoriented, could not identify close relatives, did not know the document was a will, or was under the influence of a delusion that drove the disposition.
Timing: The Lucid Interval and the Day of Signing
Capacity is not a permanent condition. Dementia progresses, delirium comes and goes with infection and medication, and a person recovering from a stroke or surgery may be lucid in the morning and confused at night. The law recognizes this by asking about the moment of signing. A will signed during a lucid interval is valid even if the signer lacked capacity before and after, and a will signed when the person lacked capacity is invalid even if the signer was clear a week earlier.
This focus on timing makes the evidence closest to the signing decisive. The drafting attorney’s notes of the meeting, the attesting witnesses’ recollection of the conversation, a physician’s evaluation the same week, nursing notes from the same day, and the signer’s own handwriting and statements around that time weigh more than a diagnosis made months earlier or a decline that came later.
Evidence in a Capacity Case
- Medical records from the months surrounding the signing: diagnoses, cognitive testing, hospitalizations, medication lists, and the day-to-day nursing and physician notes that describe orientation and behavior.
- The drafting attorney’s file and testimony: how the attorney assessed capacity, what the signer said about family and property, who was present, and whether the attorney met the signer alone.
- The attesting witnesses, who in a properly supervised signing are asked about the signer’s condition and who typically sign an affidavit at the time.
- A contemporaneous capacity evaluation, where one was obtained, by a physician, neurologist, or neuropsychologist.
- Retained expert testimony from a physician or neuropsychologist who reviews the records and gives an opinion on the signer’s likely condition on the day.
- Lay witnesses who saw the signer around the time: family, friends, aides, and neighbors.
- The document itself, including whether it is consistent with earlier plans and whether its provisions make sense for the signer’s family.
Who Bears the Burden
The allocation of the burden of proof differs by state and can decide close cases. In New Jersey, a will maker is presumed to have been of sound mind, and the person challenging the will must prove otherwise. In New York and Connecticut, the person offering the will bears the initial burden of showing that the signer had capacity, which is usually met by the testimony or affidavits of the attesting witnesses, after which the challenger must produce evidence to the contrary. In every state the practical question is the same: whose evidence about the day of signing is more persuasive.
Capacity and Undue Influence
Capacity and undue influence are separate grounds that are usually pleaded together. A signer with diminished capacity is more susceptible to pressure, so the same medical evidence supports both claims. But they are different questions. Capacity asks whether the signer understood; undue influence asks whether the signer’s own will was overcome by someone else’s. A person with full capacity can be unduly influenced, and a person with impaired capacity can sign a valid document if the impairment did not rise to incapacity and no one interfered.
Capacity for Other Documents
Different documents require different levels of understanding. The capacity to make a will is generally the lowest. Contracts, deeds, and lifetime gifts generally require the higher capacity to understand the nature and consequences of the transaction, and revocable trusts are treated under rules that vary by state. Powers of attorney and health care directives have their own standards. The result is that a person may have been able to sign a valid will but not a valid deed on the same day, and a challenge to a lifetime transfer is evaluated under a standard that is easier for the challenger to meet. Where a family discovers that an impaired relative signed a deed, added someone to an account, or changed a beneficiary designation, the capacity claim is often combined with claims of financial exploitation, and where the relative is still living, a guardianship may be part of the response.
Where and When Capacity Claims Are Raised
A capacity challenge to a will is raised as an objection in the probate proceeding. The procedure and deadlines for will contests differ by state; in some circumstances the window is a matter of months after the will is admitted. Challenges to trusts, deeds, and lifetime transfers may be brought in the same court or in a separate action. Because the medical and witness evidence deteriorates with time, an early assessment serves both sides.
What Our Testamentary Capacity Service Includes
- An early evaluation of the medical and drafting records to assess whether a capacity challenge, or a defense, is supportable.
- Objections, complaints, and defenses filed in the correct court within the applicable deadline.
- Collection of medical records, the drafting attorney’s file, and witness accounts, and examination of the attesting witnesses and the drafter.
- Retention of physicians and neuropsychologists to review the records and testify.
- Discovery, motion practice, and trial in the Surrogate’s Court, the Superior Court, or the Probate Court.
- Negotiation, mediation, and other forms of alternative dispute resolution.
- Supervised signings of wills and other documents for clients whose capacity may be questioned, including those undertaking dementia planning, with a documented assessment, independent witnesses, and, where warranted, a contemporaneous medical evaluation.
When a Capacity Challenge Is Not the Right Path
A capacity challenge is unlikely to succeed where the signer, whatever the diagnosis, could discuss family and property coherently on the day of signing, where an attorney met the signer alone and recorded the assessment, or where the will continues a long-standing plan. Forgetfulness, frailty, and unpopular choices are not incapacity. The claim is also a poor fit where the real concern is that someone pressured the signer, which is an undue influence claim, or that the executor is mishandling the estate, which calls for an accounting or a fiduciary proceeding. In those situations we advise against a capacity challenge and direct the client to the claim that fits the facts.
Schedule a Consultation About Testamentary Capacity
If a relative signed a will, trust, or deed at a time when you doubt they understood it, or if you are defending a document against that claim, a prompt review can help preserve medical and witness evidence and identify the applicable deadlines. Bring the document, any earlier versions, and what you know about the signer’s diagnoses, medications, and living situation at the time. Our attorneys practice in New York, New Jersey, and Connecticut. Contact Milvidskiy Law Group P.C. to schedule a consultation.

Frequently Asked Questions
What is testamentary capacity?
It is the mental ability required to make a valid will. The signer must understand that the document disposes of property at death, must know in general terms what property they own, and must know who their family and natural heirs are and how the will treats them. New York, New Jersey, and Connecticut each require the signer to be at least eighteen and of sound mind.
Does a dementia diagnosis mean a person cannot make a will?
No. Capacity is judged at the moment of signing, and a person with dementia may have the required understanding on a given day, particularly early in the disease. The diagnosis is evidence that a court weighs with the records and witness accounts from the time of signing. A will signed during a lucid interval can be valid.
What is a lucid interval?
A period during which a person whose capacity is generally impaired has the understanding the law requires. Conditions such as delirium, medication effects, infection, and the aftermath of a stroke fluctuate, and dementia has better and worse days. A will signed during a lucid interval is valid; the evidence must establish the person’s understanding at the time of signing.
How is lack of capacity proven?
Through medical records from around the signing, the drafting attorney’s file and testimony, the attesting witnesses’ accounts, any contemporaneous evaluation, and expert testimony from a physician or neuropsychologist who reviews the records. Lay witnesses who saw the signer at the time also matter. The evidence closest to the signing date carries the most weight.
Who has to prove capacity or the lack of it?
It depends on the state. In New Jersey, the will maker is presumed to have been of sound mind and the challenger must prove otherwise. In New York and Connecticut, the person offering the will bears the initial burden, which is ordinarily met through the attesting witnesses, after which the challenger must produce contrary evidence. In practice the case turns on whose evidence about the day of signing is more persuasive.
Is the capacity to make a will the same as the capacity to sign a deed or a contract?
No. Testamentary capacity is generally the lowest standard. Deeds, contracts, and lifetime gifts generally require a higher level of understanding of the transaction and its consequences, and other documents have their own standards. A person may have been able to sign a valid will but not a valid deed on the same day.
Can a person under guardianship make a will?
Sometimes. A guardianship or conservatorship order is strong evidence of impairment but does not by itself establish that the person lacked testamentary capacity at the moment of signing, and the rules on this point vary by state. Any will signed by a person under guardianship will be scrutinized closely, and the circumstances of the signing will decide the outcome.
What is the difference between lack of capacity and undue influence?
Capacity asks whether the signer understood what they were doing. Undue influence asks whether someone else’s will replaced the signer’s. They are separate grounds, often pleaded together, because a person with diminished capacity is more susceptible to pressure. A person with full capacity can still be unduly influenced.
How can I make sure my own will is not challenged for lack of capacity?
Sign it while you are well, with an attorney who meets you alone and records how capacity was assessed, and with independent witnesses. If you have a diagnosis that may be questioned later, obtain an evaluation from a physician or neuropsychologist close to the signing date. A documented record of your reasons for the plan, kept in the attorney’s file, is the strongest protection.
How long do I have to challenge a will for lack of capacity?
The same deadlines that apply to any will contest, which differ by state and can be short. In some circumstances the window closes within months after the will is admitted. Challenges to deeds, trusts, and lifetime transfers have their own limitation periods. Have the deadlines reviewed as soon as the document comes to light.
