Testamentary Capacity in Florida: The Short Answer<\/h2>\n

Testamentary capacity is the mental ability to make a valid will. Fla. Stat. \u00a7 732.501<\/a> sets that basic rule.<\/p>\n

Capacity is only one question a court asks when a will is challenged. Those are separate grounds, and a contest often raises several of them at once.<\/p>\n

Families usually meet this issue when an heir or beneficiary doubts a document. Trust Counsel, PL represents beneficiaries, heirs and fiduciaries in probate and trust disputes. This page explains the test in plain terms, so you know what a court is actually asking.<\/p>\n\n

Who May Make a Will in Florida Under Fla. Stat. 732.501<\/h2>\n

Any person who is of sound mind and either 18 or older, or an emancipated minor, may make a will. The phrase “sound mind” is where capacity lives. A court does not ask whether the person was healthy, wealthy or wise.<\/p>\n

Signing rules often appear in the same dispute. Fla. Stat. \u00a7 732.502<\/a> requires a will to be in writing. The testator, meaning the person making the will, must sign at the end, or another person must sign for them in their presence and at their direction.<\/p>\n

The testator’s signature or acknowledgment must be made in front of at least two attesting witnesses. Those witnesses must sign in the presence of the testator and of each other.<\/p>\n

The Elements a Court Looks At<\/h2>\n

Here is a simple example. A parent names a spouse and three adult children, knows the family home and a bank account exist, and understands the will gives each child a share. Whether a person meets the legal test depends on the facts of each case. A parent who cannot name the children or does not know the home is in the estate raises a different question.<\/p>\n

Why Capacity Is Measured at the Time of Signing<\/h2>\n

A person can have clear days and confused days, so timing is central.<\/p>\n

A diagnosis, such as dementia, does not decide the question by itself. Whether capacity existed on a given day depends on the facts, and the evidence from that period carries the most weight.<\/p>\n

Families often focus on the diagnosis or the last months of life. That focus can miss the period that matters. The right question is what the testator understood when the pen touched the paper.<\/p>\n

Who Carries the Burden of Proof in a Will Contest<\/h2>\n

The person offering the will must first show that it was formally executed and attested. Under Fla. Stat. \u00a7 733.107<\/a>, that showing is made prima facie, meaning it is enough at first look. Fla. Prob. R. 5.275<\/a> sets out the same sequence.<\/p>\n

After that first showing, the person contesting the will must establish the grounds for the challenge. Their evidence has to show why probate should be opposed.<\/p>\n

Timing matters. A will contest cannot be started before the testator dies, under Fla. Stat. \u00a7 732.518<\/a>. The statute, Fla. Stat. \u00a7 733.212<\/a>, provides that an interested person on whom a copy of the notice of administration is served must file any objection that challenges the validity of the will, the venue, or the jurisdiction of the court on or before the date that is 3 months after the date of service of a copy of the notice of administration on that person. The 3-month time period may only be extended for estoppel based upon a misstatement by the personal representative regarding the time period within which an objection must be filed. Unless sooner barred, all such objections must be filed no later than the earlier of the entry of an order of final discharge of the personal representative or 1 year after service of the notice of administration. Waiting can cost the right to object.<\/p>\n

Evidence Courts Use: Medical Records, Witnesses and the Attorney’s File<\/h2>\n

Courts look at evidence from the period around signing. Medical records are one source. Physician notes, hospital charts and cognitive evaluations from those weeks can show the testator’s condition. Records from far earlier or later may carry less weight.<\/p>\n

Witnesses add another layer. The two attesting witnesses, family members, caregivers and others who saw the testator near the signing date can describe how the person spoke, what they knew and how they acted. A physician who examined the testator may later give an opinion about capacity, and that opinion is the physician’s own.<\/p>\n

The drafting lawyer’s file can be central. Intake notes, questions asked at meetings, drafts and meeting records can show what the testator said about family, property and the plan. Families who are questioning a will often benefit from asking early what records exist.<\/p>\n\n

Capacity Versus Fraud, Duress, Mistake and Undue Influence<\/h2>\n

Lack of capacity is a different ground from the others. Under Fla. Stat. \u00a7 732.5165<\/a>, a will is void if its execution is procured by fraud, duress, mistake or undue influence. Any part procured that way is void. The rest stays valid if it is not invalid for other reasons.<\/p>\n\n

\n\n\n\n\n\n\n\n
Ground<\/th>\nCore question<\/th>\n<\/tr>\n<\/thead>\n
Fraud<\/td>\nWas the testator deceived into signing?<\/td>\n<\/tr>\n
Duress<\/td>\nWas the testator forced or threatened into signing?<\/td>\n<\/tr>\n
Mistake<\/td>\nDid the testator sign because of a materially wrong belief?<\/td>\n<\/tr>\n
Undue influence<\/td>\nDid someone pressure or control the testator’s decisions?<\/td>\n<\/tr>\n<\/tbody>\n<\/table><\/figure>\n\n

Undue influence often overlaps with capacity. A caregiver who controlled daily decisions may be relevant to both. Where a presumption of undue influence applies, Fla. Stat. \u00a7 733.107<\/a> states that the presumption shifts the burden of proof. That presumption protects against abuse of fiduciary or confidential relationships.<\/p>\n

Related Questions About Trusts, Trustees and Personal Representatives<\/h2>\n

Capacity disputes often sit beside questions about trusts and estate administration. Trust litigation in Florida<\/a> covers disputes over trusts, wills and the people who run them. Trust Counsel’s attorneys can serve individually as trustee or personal representative. The firm advises and represents trustees, personal representatives and beneficiaries.<\/p>\n

Readers often ask how a fiduciary steps aside. See trustee resignation in Florida. A personal representative (often called an executor) may face the same question. See personal representative resignation in Florida.<\/p>\n

Some readers also ask whether assets can be sold while a contest is pending. That question is covered at trust property sales during a contest.<\/p>\n
