Lack of Capacity and Will Validity

When a will surfaces that does not match what a loved one always said they wanted, families in Palm Beach often ask the same hard question: was the person even capable of making this decision? Florida law calls this issue testamentary capacity. Here are the answers people look for.

What does Florida require to make a valid will?

Florida sets out the formalities in Section 732.502: the will must be in writing, signed by the maker at the end, and witnessed by two people who sign in the maker’s presence and in the presence of each other. Beyond the signing formalities, the person must also have had the mental capacity to make a will at the moment they signed it. Both pieces matter; a perfectly witnessed document can still fail if capacity was missing.

What is the actual standard for testamentary capacity?

The Florida standard is more forgiving than many families expect. To have capacity, the person generally needs to understand, in a general way, the nature and extent of their property, the natural objects of their bounty (typically close family), and how the will distributes their property among them. They do not need a perfect memory or sharp focus on every detail. A diagnosis of dementia, by itself, does not automatically void a will.

Then how can someone with dementia sign a valid will?

Because capacity is measured at the specific moment of signing. Florida recognizes that people with cognitive decline can have lucid intervals. A person with a memory disorder may, on a given afternoon, clearly understand their property and family well enough to sign a valid will. This is why these cases turn on close evidence about that particular day rather than a general label.

What evidence shows lack of capacity?

The strongest evidence is contemporaneous: medical records and physician notes from around the signing date, prescriptions and their cognitive side effects, hospital admissions, and observations from people who interacted with the person at the time. The drafting attorney’s notes and the witnesses’ recollections often carry significant weight, because they describe how the person presented when the will was actually executed.

How does this relate to undue influence?

The two claims are cousins and frequently travel together. Diminished capacity can make a person more susceptible to pressure, so a will challenge may argue both that the person did not fully understand what they signed and that someone improperly influenced the result. They are separate legal theories with separate proof, but the same facts often support each.

What about a trust instead of a will?

Many Palm Beach residents use revocable trusts under Chapter 736 to manage assets and avoid probate. The capacity needed to create or amend a trust is generally measured by the same kind of standard that applies to wills. So a trust amendment made during serious cognitive decline can be challenged on similar grounds.

How quickly do I need to act?

Quickly. Florida imposes firm deadlines to object once a will is admitted to probate, and evidence about someone’s mental state fades fast. Securing medical records and identifying witnesses early can make or break a capacity challenge.
