Contesting a will in Florida means asking the probate court to declare a will invalid, in whole or in part, on a recognized legal ground such as lack of capacity, undue influence, fraud, or improper execution. Only an “interested person”—typically an heir or beneficiary whose share is affected—has standing to bring the challenge, and they must do so within a tight statutory window once formal administration begins. If the court agrees, the contested will is set aside and the estate passes under a prior valid will or, absent one, under Florida’s intestacy laws.
That is the short answer. The longer answer is where most families get tripped up, because a Florida will contest is not won by feeling that something was wrong. It is won with evidence, filed on time, in the right forum, against a statutory presumption that the will is valid. Below is how the grounds and the process actually work in our state, written from years of handling these disputes in South Florida probate divisions.
Who Can Contest a Will in Florida?
Standing matters more than people expect. Under Florida law, only an interested person may object to a will. The Florida Probate Code (Fla. Stat. § 731.201) defines an interested person as someone who may reasonably be expected to be affected by the outcome of the proceeding. In practice that usually means:
- A beneficiary named in the current or a prior will whose inheritance is reduced or eliminated;
- An heir who would inherit under Florida’s intestacy statute if the will failed;
- A creditor, in narrower circumstances, where the estate’s solvency is at stake.
A disappointed friend, a caregiver who expected to be remembered, or a distant relative who would not inherit either way generally has no standing. The first question we ask any prospective client is not “what went wrong?” but “what would you receive if this will were thrown out?” If the answer is nothing, there is no case to bring, no matter how unfair the document feels.
The Grounds for Contesting a Will
Florida recognizes a defined set of grounds. A vague sense of unfairness is not one of them. The four that drive nearly every contest are improper execution, lack of testamentary capacity, undue influence, and fraud or duress.
1. Improper Execution (Failure to Follow Formalities)
Florida is strict about how a will must be signed. Under Fla. Stat. § 732.502, a valid will requires the testator’s signature at the end, made in the presence of two attesting witnesses, who must in turn sign in the presence of the testator and of each other. Miss one of those steps and the document can fail entirely.
This is also why Florida does not recognize handwritten (holographic) wills unless they happen to be executed with the same two-witness formality—and it does not recognize oral wills at all. A note in a drawer, signed but unwitnessed, is not a will here. Execution challenges are often the cleanest to prove because they turn on what happened in the room, not on the testator’s state of mind.
2. Lack of Testamentary Capacity
To make a valid will, the testator must understand, at the moment of signing, the nature and extent of their property, who their natural beneficiaries are (the “objects of their bounty”), and how the will distributes the estate. The bar is lower than many families assume. A person can be forgetful, physically frail, even diagnosed with early dementia, and still possess a lucid interval sufficient to execute a valid will.
That is the hard truth in capacity cases. A diagnosis alone rarely wins. What moves a court is contemporaneous evidence—medical records dated near the signing, the drafting attorney’s notes, witness testimony about the testator’s confusion that day. We frequently see capacity and undue influence pleaded together, because diminished capacity makes a person far more susceptible to pressure.
3. Undue Influence
Undue influence is the most litigated ground in Florida and the one our firm sees most often in guardianship-adjacent estates. It is not mere persuasion or a close relationship. It is overpowering the testator’s free will so that the will reflects the influencer’s intent rather than the testator’s own.
The landmark case, In re Estate of Carpenter, 253 So. 2d 697 (Fla. 1971), set out factors courts weigh: whether the influencer was present at execution, recommended the attorney, knew the contents beforehand, gave instructions to the drafter, secured witnesses, or kept the will afterward. Florida later codified a critical procedural rule in Fla. Stat. § 733.107: once a contestant shows the alleged influencer was a substantial beneficiary who occupied a confidential relationship with the decedent and was active in procuring the will, a presumption of undue influence arises and the burden shifts to the proponent to prove the will was legitimate.
That burden shift is decisive. It converts a near-impossible “prove what happened behind closed doors” problem into a manageable one. We see these patterns most clearly in cases that begin as contested guardianships—where a single relative or caregiver isolates an elderly person, controls access to lawyers and finances, and a new will surfaces shortly before death. The guardianship record itself often becomes the strongest evidence in the later will contest.
4. Fraud, Duress, and Mistake
Under Fla. Stat. § 732.5165, a will procured by fraud, duress, or undue influence is void. Fraud comes in two forms: fraud in the execution (the testator was deceived about what they were signing) and fraud in the inducement (the testator was fed lies that shaped the bequests—for example, a false claim that one child stole money or abandoned the parent). Duress involves coercion or threats. These grounds are powerful but evidence-heavy; courts demand specific proof of the deception or threat, not suspicion.
The Florida Will Contest Process, Step by Step
The procedure is as important as the grounds. Many meritorious challenges die not on the merits but on a missed deadline. Here is the typical sequence in a formal administration:
- The will is admitted to probate. The personal representative files the will and petitions for formal administration in the circuit court of the county where the decedent lived—Miami-Dade, Broward, or Palm Beach for most of our clients.
- Notice of Administration is served. Under Fla. Stat. § 733.212, interested persons receive formal notice. This document starts the clock.
- The objection deadline runs. An interested person served with the Notice of Administration generally has three months (90 days) from the date of service to file an objection challenging the will’s validity, the qualifications of the personal representative, or the court’s jurisdiction. Miss it and the objection is forever barred, absent fraud or another narrow exception.
- The contest is litigated. Once an objection is filed, the matter proceeds like civil litigation: pleadings, discovery (depositions, document requests, the drafting attorney’s file, medical records), and often expert testimony from physicians or forensic document examiners.
- Mediation. Florida probate courts routinely order mediation. A large share of will contests settle here, which spares the family the cost and exposure of trial.
- Trial and judgment. If no settlement is reached, the probate judge—there is no jury in Florida probate—decides. If the will is invalidated, the estate passes under a prior valid will or by intestacy under Fla. Stat. Chapter 732.
Where probate has already concluded, a different path applies. Fla. Stat. § 733.109 allows a petition to revoke probate, but the timing and grounds are far more constrained. The lesson is the same: act early. Once the Notice of Administration is served, the 90-day window is the single most important date in the entire matter.
What Invalidating a Will Actually Accomplishes
A successful contest does not let the court rewrite the will to be “fair.” The court’s job is binary: the will stands, or it falls. If it falls, the estate is governed by the most recent valid prior will, and if none exists, by Florida intestacy. That is why we always investigate whether an earlier will exists before filing—because invalidating a 2024 will only helps the client if the 2019 will, or the intestacy result, leaves them better off. Strategy here is everything.
The mechanics of how an estate is then administered—appointing the personal representative, marshaling assets, paying creditors, and distributing what remains—follow the standard probate framework. For families managing assets across state lines, our colleagues handle these same questions in New York; their overview of is a useful comparison point, and their detailed explanation of shows how grounds like undue influence travel across jurisdictions, even when the procedural deadlines differ.
The “In Terrorem” Clause and the Cost of Contesting
Many wills include a no-contest clause (an in terrorem provision) that purports to disinherit any beneficiary who challenges the document. Here Florida is unusually friendly to contestants: under Fla. Stat. § 732.517, such clauses are unenforceable. A beneficiary who contests in good faith does not forfeit their bequest simply for asking the court to examine the will. That removes a major deterrent that exists in many other states.
Fees are a separate consideration. Florida law (Fla. Stat. § 733.1061) gives courts discretion to award attorney’s fees and even to impose them as a sanction in will-contest litigation, depending on the parties’ conduct. A contest brought in bad faith carries real risk. A well-founded one, prosecuted carefully, can recover costs from the estate or the losing party in the right circumstances.
Practical Advice Before You File
If you suspect a Florida will is invalid, three steps protect your position:
- Preserve evidence immediately. Medical records, the drafting attorney’s file, prior wills, bank records, and communications fade or disappear. The earlier we issue litigation holds and subpoenas, the stronger the case.
- Confirm your standing and the better outcome. Verify that invalidating the will actually improves your position under a prior will or intestacy.
- Watch the calendar. The 90-day objection clock starts the day you are served with the Notice of Administration. Do not wait to “see how things develop.”

Frequently Asked Questions
How long do I have to contest a will in Florida?
If you are served with a formal Notice of Administration under Fla. Stat. § 733.212, you generally have three months (90 days) from the date of service to file an objection challenging the will. Missing this deadline usually bars the contest permanently, absent fraud or another narrow exception, so it is critical to consult a probate attorney as soon as you receive notice.
What are the legal grounds for contesting a will in Florida?
Florida recognizes four main grounds: improper execution (the will was not signed and witnessed as Fla. Stat. § 732.502 requires), lack of testamentary capacity, undue influence, and fraud or duress. Under Fla. Stat. § 732.5165, a will procured by fraud, duress, or undue influence is void. General unfairness is not a legal ground.
Who is allowed to contest a will in Florida?
Only an ‘interested person’ as defined in Fla. Stat. § 731.201 has standing—typically a beneficiary named in a current or prior will, or an heir who would inherit under Florida intestacy if the will failed. You must be financially affected by the outcome; a person who would receive nothing either way usually cannot bring a contest.
Can a no-contest clause stop me from challenging a Florida will?
No. Under Fla. Stat. § 732.517, no-contest (in terrorem) clauses are unenforceable in Florida. A beneficiary can challenge a will without automatically forfeiting their inheritance, which makes Florida more contestant-friendly than many other states on this point.
What happens to the estate if a will is successfully contested?
The court cannot rewrite the will to be fair—it either upholds or invalidates it. If the will is set aside, the estate passes under the most recent valid prior will, or, if none exists, under Florida’s intestacy laws in Chapter 732. That is why it is important to confirm a prior will or intestacy actually improves your position before filing.
