Contesting a Will in Florida: Grounds and Process Explained

Contesting a will in Florida means asking a probate court to declare all or part of a will invalid, usually because the document does not reflect the true, freely made wishes of the person who signed it. A challenge can only proceed after the testator has died and the will is offered for probate, and it must rest on a recognized legal ground such as lack of capacity, undue influence, fraud, duress, or improper execution. Most contests in Florida are governed by strict deadlines under the Florida Probate Code, and missing one of them usually ends the case before it begins.

Few moments are as painful as discovering, in the weeks after a parent or spouse dies, that a will says something you never expected. Maybe a longtime caregiver now inherits everything. Maybe a signature looks wrong. Maybe a sibling who controlled Mom’s finances also controlled her estate plan. Families come to us in South Florida every week with that exact knot in their stomach. This article walks through what it actually takes to challenge a will here, what the law requires you to prove, and how the process unfolds in a Florida probate courtroom.

What Does It Mean to Contest a Will in Florida?

A will contest is a formal legal objection filed in the probate proceeding where the will is being administered. You are not simply complaining that the document feels unfair. Florida law gives broad freedom to leave property however a person wishes, and a will can be lopsided, surprising, or even cruel without being illegal. To win, you have to show that the will is legally defective for a specific reason the courts recognize.

The challenge happens inside the probate case itself, typically in the circuit court of the county where the decedent lived. In our region that usually means the probate divisions in Miami-Dade, Broward, or Palm Beach County. The person challenging the will is the petitioner; the person defending it, often the named personal representative, carries the document forward.

Two threshold rules matter before anything else. First, under Florida Statutes section 732.518, a will cannot be contested until the testator has died. There is no challenging Grandpa’s will while he is alive and sitting at the kitchen table. Second, you must have standing.

Who Has Standing to Challenge a Will?

Only an “interested person” can contest a will in Florida. In practical terms, that means someone who stands to lose or gain depending on whether the will is upheld. The usual categories include:

• Heirs at law — the relatives who would inherit under Florida’s intestacy statutes if there were no valid will at all (children, spouse, parents, siblings).
• Beneficiaries under a prior will — if an earlier, more favorable will would take effect once the current one is set aside.
• Beneficiaries under the contested will who object to a specific provision or to a later codicil.
• Creditors, in narrow circumstances tied to their claims.

If you would receive nothing whether the will stands or falls, you generally have no right to contest it. A friend left out of the will, with no prior will naming them and no intestate share, typically lacks standing. This is the first question we work through with any prospective client.

Legal Grounds for Contesting a Will in Florida

You cannot challenge a will on a hunch. Florida recognizes a defined set of grounds, and your petition must allege facts supporting at least one of them.

1. Lack of Testamentary Capacity

To make a valid will, the testator must have had a “sound mind” at the moment of signing. Florida sets that bar lower than many people assume. The testator only needs to have understood, in a general way, three things: the nature and extent of their property, the natural objects of their bounty (the people who would ordinarily inherit, like children and a spouse), and how those elements relate in the plan they were making.

A diagnosis of dementia or Alzheimer’s does not automatically void a will. Capacity is measured at the time of execution, and someone with a progressive illness may still have lucid intervals. That is why medical records, the testimony of the witnesses to the signing, and contemporaneous notes from the drafting attorney carry so much weight. The question is not whether the person was old or ill, but whether they understood what they were doing when the pen hit the paper.

2. Undue Influence

Undue influence is the ground we see most often in disputed estates, and it is the heart of many South Florida family fights. It occurs when someone in a position of trust overpowers the free will of the testator so that the will reflects the influencer’s desires rather than the testator’s own. Persuasion, affection, and even pestering are not enough; the influence must amount to a kind of mental coercion that destroys free agency.

Florida’s seminal case, In re Estate of Carpenter, lays out the framework. A presumption of undue influence arises, shifting the burden of explanation, when three elements line up:

1. The alleged influencer was a substantial beneficiary under the will;
2. They occupied a confidential or fiduciary relationship with the testator; and
3. They were active in procuring the will.

To gauge that third element, courts examine the Carpenter factors: who was present when the will was executed, who knew about it ahead of time, who recommended the attorney, who gave the instructions, who paid for it, and who kept the signed document afterward. A daughter who drives Dad to a lawyer she chose, sits in on the meeting, relays his “wishes,” and then takes the original home in her purse has checked several of those boxes. Under section 733.107 of the Florida Statutes, once the presumption attaches, the burden shifts to the person who benefited to prove the will was not the product of undue influence.

3. Fraud

Fraud comes in two flavors. Fraud in the execution happens when the testator is deceived about the very nature of the document — told they are signing a power of attorney when it is actually a will, for instance. Fraud in the inducement happens when someone feeds the testator a lie that causes them to change their plan, such as falsely telling a parent that one child has died or stolen from them. Either form, if proven, voids the affected provisions.

4. Duress and Coercion

A will signed under threats — physical, financial, or emotional — is invalid. Duress overlaps with undue influence but involves a more overt element of force or fear.

5. Improper Execution

Florida has firm formalities for signing a will, set out in section 732.502. The testator must sign at the end of the document (or direct another to sign in their presence), and two witnesses must sign in the presence of the testator and of each other. A will that flunks these mechanics can be thrown out no matter how clearly it states the decedent’s intent. Holographic (handwritten, unwitnessed) wills and oral wills are not valid in Florida, even if they would be honored in another state.

6. Revocation, Mistake, and Forgery

Other grounds include a later will or codicil that revoked the one being probated, a genuine mistake in the document’s contents, and outright forgery of the testator’s signature. Under section 732.5165, a will procured by fraud, duress, mistake, or undue influence is void; if only part of the will is tainted, the court may strike that portion and let the rest stand.

The Critical Deadlines: Don’t Wait

Nothing sinks a meritorious will contest faster than the calendar. When an estate is opened, the personal representative serves a Notice of Administration on interested persons under Florida Statutes section 733.212. That notice triggers a hard 90-day window to file objections to the validity of the will, the qualifications of the personal representative, or the venue and jurisdiction of the court. An interested person who is served and lets those three months pass is generally barred forever from raising those challenges.

The deadline is unforgiving, and Florida courts enforce it strictly. If you have received any paperwork from a probate estate, treat it as urgent. Even when you have not been formally served, waiting invites problems — assets get distributed, witnesses’ memories fade, and the cost of unwinding a partly administered estate climbs. The practical takeaway: the day you suspect a problem is the day to call a lawyer, not the day to start gathering courage.

The Will Contest Process in a Florida Probate Court

Once a contest is on file, it proceeds much like other civil litigation, but inside the probate framework. Here is the usual arc.

1. Investigation and review. Before filing, counsel gathers the will and any prior versions, the drafting attorney’s file, the decedent’s medical and financial records, and statements from people close to the testator. This is where a case is made or quietly abandoned.
2. Filing the petition or objection. The challenge is initiated by a petition to revoke probate (under section 733.109 if the will was already admitted) or by a timely objection. It must state the specific grounds and the facts behind them.
3. Discovery. Both sides exchange documents, take depositions of witnesses, family members, the drafting lawyer, and treating physicians, and often retain experts — a geriatric psychiatrist on capacity, a forensic document examiner on a questioned signature.
4. Mediation. Florida courts routinely order probate disputes to mediation. The large majority of will contests settle here, because litigation is expensive, slow, and emotionally corrosive for a grieving family.
5. Trial. If no settlement is reached, a judge (probate matters are tried without a jury) hears the evidence and decides whether the will, or the challenged portion, is valid.
6. Outcome and appeal. The court may uphold the will, invalidate it entirely, or strike specific provisions. If the whole will falls and there is no valid prior will, the estate passes by intestacy. Any party may appeal.

Who Has the Burden of Proof?

The allocation of proof is decisive and often misunderstood. Generally, the person offering the will (the proponent) must first establish that it was properly executed. Once that prima facie showing is made, the burden shifts to the contestant to prove a ground of invalidity such as lack of capacity or undue influence. As noted above, section 733.107 then re-shifts the burden back to a substantial beneficiary in a confidential relationship who was active in procuring the will, requiring them to dispel the presumption of undue influence by the greater weight of the evidence. These shifts are technical, and how they play out shapes the entire strategy of a case.

What About No-Contest Clauses?

Many wills include an “in terrorem” or no-contest clause warning that any beneficiary who challenges the will forfeits their inheritance. Beneficiaries in other states have to weigh that risk carefully. Florida does not. Under Florida Statutes section 732.5135, a provision in a will purporting to penalize an interested person for contesting the will or instituting other proceedings is unenforceable. You will not lose your bequest in a Florida estate merely for raising a good-faith challenge. This is one of the most beneficiary-friendly rules in the country, and it removes a major deterrent that stops families elsewhere from coming forward.

How a Florida Probate Attorney Helps

Will contests are document-heavy, deadline-driven, and emotionally charged. An experienced attorney evaluates whether you have standing and a viable ground, preserves evidence before it disappears, files within the 90-day window, and manages the burden-shifting that decides close cases. Just as important, good counsel will tell you honestly when a will is unfair but legally sound — saving you the cost of a fight you cannot win.

Frequently Asked Questions

How long do I have to contest a will in Florida?

If you were served with a Notice of Administration, you generally have 90 days from the date of service to file an objection challenging the validity of the will, the qualifications of the personal representative, or the court’s jurisdiction and venue, under Florida Statutes section 733.212. Missing that deadline usually bars the challenge permanently, so it is critical to act as soon as you suspect a problem.

What are the main legal grounds for contesting a will in Florida?

Florida recognizes lack of testamentary capacity, undue influence, fraud, duress, improper execution (such as a will that was not signed before two witnesses as required by section 732.502), mistake, forgery, and revocation by a later will. A contest must be based on one of these specific grounds, not simply on the belief that the will is unfair.

Can I lose my inheritance for challenging a will in Florida?

No. Under Florida Statutes section 732.5135, no-contest (in terrorem) clauses are unenforceable. A provision that tries to disinherit a beneficiary for challenging the will has no legal effect in Florida, so a good-faith contest will not, by itself, cost you your bequest.

Who is allowed to contest a will in Florida?

Only an ‘interested person’ has standing, meaning someone whose financial interest would be affected by whether the will is upheld. That typically includes heirs who would inherit under intestacy law, beneficiaries named in a prior will, and beneficiaries under the contested will. Someone who would receive nothing either way generally cannot contest it.

Does a dementia diagnosis automatically invalidate a will in Florida?

No. Testamentary capacity is judged at the moment the will was signed, and a person with dementia or Alzheimer’s may still have had a lucid interval and understood their property, their family, and their plan. Proving incapacity requires evidence about the testator’s mental state at the time of execution, often through medical records, the signing witnesses, and the drafting attorney.
