How A Florida Testamentary Capacity Evaluation Works

A testamentary capacity evaluation answers one legal question: did this person meet Florida’s standard for a sound mind at the moment they signed the will? A dementia diagnosis does not settle it. A will that looks unfair does not settle it either. What settles it is whether, at that specific moment, the signer met the three-part test Florida courts have applied since 1918.

There are two versions of this evaluation. One happens before signing, while the person is alive and can sit for an interview. The other happens after death, and the evaluator rebuilds that moment from records, pharmacy data, and the people who were in the room. The second kind is harder. It’s also the kind most attorneys call us about.

What Is A Testamentary Capacity Evaluation?

A testamentary capacity evaluation is a forensic psychological assessment of whether a person had the mental ability to make or change a will at the time they signed it. A licensed psychologist reviews records, interviews the signer or other witnesses, runs testing, and maps the findings to the state’s legal test for capacity.

That last part is where most reports fail. A clinical write-up describes a person. A forensic report answers a legal question. Those are different documents. A judge can tell.

Florida is where this work is busiest, which is why our Florida forensic psychology practice sees capacity referrals year round. The US Census Bureau puts 22.8 percent of Florida’s population at 65 or older. Set that against a July 1, 2025 population estimate of 23,462,518 and you get about 5.3 million residents in the age band where capacity gets contested. We’ve been writing forensic evaluations for the 15th Judicial Circuit since 2008, and capacity referrals have never been a side line.

Florida’s Test Comes From A 1918 Case, Not A Statute

The statute is one sentence. Florida Statute 732.501 says: “Any person who is of sound mind and who is either 18 or more years of age or an emancipated minor may make a will.” It never defines sound mind.

The definition comes from case law. In Newman v. Smith, 77 Fla. 633, 82 So. 236 (1918), the Florida Supreme Court set out three things the signer has to understand in a general way. The nature and extent of the property being given away. Their relation to the people who would naturally expect a substantial benefit. And the practical effect of the will as executed. Florida appellate courts still quote that language. The Third District quoted it in American Red Cross v. Estate of Haynsworth, 708 So. 2d 602 (Fla. 3d DCA 1998).

Three things follow from that wording. Attorneys miss all three often enough to be worth stating plainly.

“In a general way” is a low bar. The signer does not need to recite account balances. Courts ask for general understanding, not an audit.

Capacity is measured at the moment of execution, not across the illness. Florida recognizes lucid intervals. In In re Estate of Supplee, 247 So. 2d 488 (Fla. 2d DCA 1971), the court treated even an adjudication of incompetency as a presumption that proof of a lucid interval can overcome.

And the same standard reaches further than wills. Florida Statute 736.0601 says the capacity to create, amend, revoke, or add property to a revocable trust “is the same as that required to make a will.” That surprises people, because a trust feels like a contract. The statute says otherwise. If your fight is over a trust amendment, the evaluator is answering the same three questions.

How Do The Legal Elements Map To Psychological Evidence?

Each prong of the Florida test matches a different mental function and a different document. Nobody wins a capacity fight by arguing about a diagnosis. They win by matching evidence to elements.

Florida legal element	What the evaluator measures	Which record proves it	Where it usually falls apart
Nature and extent of the property	Semantic memory for assets, working memory, basic financial reasoning	Bank and brokerage statements, the asset schedule in the drafting file, the signer’s own words in attorney notes	The file lists the assets. It rarely records whether the signer named them unprompted
Relation to those who would naturally claim a benefit	Recall of family structure, insight, and any fixed false belief about a relative	Attorney intake notes, prior wills, family testimony, treating clinician notes	A delusion only matters if it touches this element. General paranoia is not enough
Practical effect of the will as executed	Understanding, reasoning, ability to hold the whole plan in mind at once	Signing records, video, witness affidavits, the drafter’s notes that day	People repeat a plan back without understanding it. Almost nobody tests for that at signing
The moment of execution	Fluctuation across a day and across weeks, medication timing and effect	Pharmacy fill records, time-stamped nursing notes, hospital flow sheets	Records are dated to the day. Opinions get written about months

Print that table and read it against the file you already have. Most contested estates come out strong on rows one and two and empty on row three. The signing itself was a five-minute formality nobody wrote down.

The Medical Chart Is The Weakest Evidence In The File

Attorneys push back on this one. In a Florida capacity fight, the medical chart proves less than the drafting attorney’s notes. And the absence of a dementia diagnosis proves almost nothing.

Start with how rare a recorded diagnosis is. The CDC’s National Center for Health Statistics reported in National Health Statistics Reports No. 203 that in 2022, 4.0 percent of adults age 65 and older said they had ever received a dementia diagnosis. Among adults 85 and older it was 13.1 percent. The same report notes something sharper. Only about 40 to 60 percent of people with dementia, found through cognitive testing or Medicare claims, reported a diagnosis in surveys.

Read that twice. A large share of people who have dementia have no diagnosis on record. So “there was nothing in the chart” is not evidence of capacity. It’s evidence that nobody looked.

The reverse is just as weak. A diagnosis in the chart tells you a condition existed. It does not tell you what the person understood on a Tuesday afternoon in March. Florida’s lucid interval doctrine exists precisely because courts refused to treat a condition as a verdict.

Thomas Gutheil named this error in 2007, in the Journal of the American Academy of Psychiatry and the Law. He listed two versions of it. One is using a diagnosis as a stand-in for what the person could do. The other is treating a low test score as if it were the legal test itself. Both get experts thrown out.

Four things carry more weight. Notes taken that day by the person who ran the signing. Accounts from witnesses who spoke with the signer. Pharmacy records showing what drugs were in their system. And any record of the signer naming their own assets and family without being prompted.

Contemporaneous Versus Retrospective Evaluations

A contemporaneous evaluation happens before or around signing, with the testator available. A retrospective evaluation happens after death, and the evaluator reconstructs the moment from the record. You will also see the second one called a psychological autopsy.

	Contemporaneous	Retrospective
Who is interviewed	The testator, plus collateral witnesses	Collateral witnesses only
Direct testing possible	Yes	No
Strongest evidence	The evaluator’s own observation and testing at the relevant time	Time-stamped records and the drafting attorney’s notes
Weakest point	Cost and timing, before anyone is in a dispute	Every opinion is an inference, and hostile witnesses supply the data
Who usually orders it	Estate planning counsel, or family anticipating a fight	Litigation counsel, after a contest is filed
Effect on the case	Often ends the argument before it starts	Becomes the argument

Gutheil drew the same line in 2007. Before death, the evaluator can test the legal criteria directly with the person. After death, the evaluator works from data nobody gathered with those criteria in mind, often supplied by people with a stake in the outcome. Kenepp and colleagues said the same in a 2021 review in Frontiers in Psychology. Assessment after death is less reliable, because thinking varies over time.

The practical version: an evaluation ordered before signing can end the argument before it starts. Most estate planning attorneys never order one.

What Happens When There Is No One Left To Interview?

The evaluator rebuilds the moment from four sources. The order matters. Records first. Then interviews. Then the mapping. Then the limits.

Records come first. They are the only evidence nobody shaped after the fact. Medical records, cognitive testing if any was ever done, pharmacy fill records, nursing notes with time stamps, prior wills, the drafting file, and financial statements from the relevant window.

Interviews come second. They get weighted, not just collected. The neighbor who saw the signer weekly and stands to gain nothing is worth more than the beneficiary who moved in six months before the signing. An evaluator who treats every witness account as equal has not done the work.

Then the mapping. Every finding gets tied to one element of the Florida test, in writing, with the source named. Findings that touch no element stay out of the opinion section.

Then the limits. A retrospective opinion should say on its face what it cannot prove. Gutheil described postmortem work as a matter of inference, extrapolation, and cross-confirmation rather than observation. An expert who says that first on direct does not get taken apart with it on cross. An expert who claims more certainty than the record supports does.

Our standard forensic evaluation runs about 10 hours of evaluator time across records review, interview, mental status exam, collateral contacts, testing, scoring, and report writing. Retrospective files with heavy medical records run longer.

No Test Score Answers The Legal Question

There is no single test that measures testamentary capacity, and any expert who says a score settles it is handing you a Daubert problem.

Screening tools like the MMSE and MoCA measure thinking in general. They were built to flag impairment, not to answer a legal element. A person can score in the impaired range and still have understood the nature of their property, their family, and their plan. A person can score in the normal range and hold a fixed false belief about one child that goes to the second element directly.

Purpose-built instruments exist, and they are not ready to carry a case alone. A 2021 review in Frontiers in Psychology looked at three of them. The Testamentary Capacity Instrument, the Legal Capacity Questionnaire, and the Testamentary Capacity Assessment Tool. Kenepp and colleagues flagged limits on each. One is screening-only with thin validity data. Another was tested only in people who already had dementia.

So testing supports the opinion. It does not replace it. Our batteries match the instruments to the referral question. The MMPI-3, PAI, M-FAST, and SIRS-2 are among the standard measures. A full neuropsychological battery gets added when the referral turns on thinking and memory. When response validity is in doubt, we screen for it with validated measures, not clinical hunch. Same discipline we apply when detecting malingering in forensic evaluations.

Undue Influence Runs In The Opposite Direction

Undue influence is a separate ground from lack of capacity, and the two move inversely. Under Florida Statute 732.5165, a will is void if its execution was procured by fraud, duress, mistake, or undue influence. That’s a different question from whether the signer understood what they were doing.

Kenepp and colleagues put it this way. Influence runs on a scale that moves opposite to thinking ability. Someone impaired can be swayed with very little pressure. Someone sharp takes heavy coercion. So a clean capacity finding does not clear the undue influence claim. It raises the bar on it.

Burden matters too. Florida Statute 733.107(1) puts the burden on the proponent to establish prima facie the will’s formal execution and attestation, and a self-proving affidavit does that. After that, the contestant carries the burden on the grounds of the challenge. Subsection (2) then provides that where the presumption of undue influence applies, it shifts the burden of proof. A capacity challenge and an undue influence challenge therefore run on different tracks, and the evaluator needs to be told which question is actually being asked.

What Makes A Capacity Opinion Survive Daubert In Florida?

Florida runs expert testimony under Florida Statute 90.702. The testimony has to rest on sufficient facts or data. It has to come from reliable principles and methods. And the witness has to apply those methods reliably to the facts of the case.

Capacity opinions almost never fail on prong two. The science of cognitive assessment is settled. They fail on prongs one and three.

Prong one fails when the evaluator worked from a thin record. If nobody pulled the pharmacy fills or the time-stamped nursing notes, the opinion rests on a chart summary and a few interviews.

Prong three fails when the report never connects the data to the legal elements. A report that concludes “the decedent had moderate Alzheimer’s disease and therefore lacked testamentary capacity” has skipped the step the statute requires. Alzheimer’s is a diagnosis. Testamentary capacity is a three-part legal test. The report has to walk from one to the other in writing.

Every report we issue is built to the section 90.702 rules. It carries separate sections on method reliability, on the qualifications behind each opinion, and on the chain from data collected to answer reached. Where a challenge is likely, the methods section answers it in advance instead of leaving it for cross. It’s the same build we use for proving a traumatic brain injury under that standard. It’s also why hiring an unqualified forensic psychologist hurts a case more than having no expert at all.

Turnaround And Scheduling In 2026

Standard evaluations are delivered within 30 days of the final assessment session. Rush work under 14 days is available depending on case complexity and current schedule, but it has to be arranged at intake. We don’t accept a rush deadline we can’t meet.

Fees run as a flat retainer paid in full at engagement, covering records review, interviews, testing, scoring, report writing, and one round of attorney consultation. Deposition and trial testimony bill separately at an hourly rate with a half-day minimum. You get a written engagement letter naming the scope, the deliverables, and the assigned evaluators before any work starts. For testimony we ask for 21 days’ notice where the calendar allows.

Our four doctors have testified across the 1st, 2nd, 15th, 17th, 19th, and 20th circuits. First licensure dates run from 2007 to 2014. One of them holds a Psy.D., a J.D., and board certification in neuropsychology. That is a hard set for opposing counsel to match in a capacity fight.

One thing we won’t do is promise an answer. An expert who shapes findings to the retaining party’s theory gets impeached. That hurts the case more than having no expert. Capacity work is the same as competency work in criminal court: the question is fixed to a moment, and the answer is whatever the record supports.

If a testamentary capacity question is sitting in your file, the first call with retaining counsel is free. We’ll walk the referral question, name the records you’ll need to produce, and tell you if we’re not the right fit. Start with our forensic evaluation services, contact the practice directly, or call (561) 870-0411.

FAQs

Can someone with dementia still make a valid will in Florida?

Yes, in some cases. Florida measures testamentary capacity at the moment of execution, not across the course of an illness, and the state recognizes lucid intervals. In In re Estate of Supplee, a Florida appellate court held that even an adjudication of incompetency creates a presumption that proof of a lucid interval can overcome. A diagnosis is one piece of evidence, not a verdict.

Who can perform a testamentary capacity evaluation in Florida?

A licensed psychologist or psychiatrist with forensic training. The license matters less than whether the evaluator writes to the legal standard. Florida Statute 90.702 requires that an expert apply reliable methods reliably to the facts of the case, so a report that stops at a diagnosis without mapping to the three-part capacity test is exposed on cross regardless of who signed it.

How long does a testamentary capacity evaluation take?

Our standard evaluations are delivered within 30 days of the final assessment session, and the underlying work runs about 10 hours of evaluator time across records review, interview, mental status exam, collateral contacts, testing, scoring, and report writing. Rush work under 14 days is available depending on complexity and schedule, arranged at intake. Retrospective files with heavy medical records take longer.

What is a retrospective testamentary capacity evaluation?

It’s an evaluation performed after the testator has died, sometimes called a psychological autopsy. The evaluator reconstructs the person’s mental state at the moment of signing using medical records, pharmacy fill records, time-stamped nursing notes, prior wills, the drafting file, and interviews with people who observed the signer during that window. It is less reliable than evaluating someone in person, which is why the report should state its own limits on its face.

Does a dementia diagnosis prove someone lacked testamentary capacity?

No, and the absence of one proves even less. The CDC’s National Center for Health Statistics reported that in 2022 only 4.0 percent of adults 65 and older said they had ever received a dementia diagnosis, and that only about 40 to 60 percent of people with dementia documented by cognitive testing or Medicare claims reported one in surveys. A clean chart often means nobody tested, not that nothing was wrong.

Is testamentary capacity the same standard for a revocable trust in Florida?

Yes. Florida Statute 736.0601 states that the capacity to create, amend, revoke, or add property to a revocable trust is the same as that required to make a will. A trust feels like a contract, so people assume a contract standard applies. The statute says otherwise, and a trust amendment fight is evaluated against the same three elements.

Who has the burden of proof in a Florida will contest?

Florida Statute 733.107(1) puts the initial burden on the proponent to establish prima facie the will’s formal execution and attestation, which a self-proving affidavit satisfies. The contestant then carries the burden of establishing the grounds of the challenge. Where the presumption of undue influence applies, subsection (2) shifts the burden of proof.
