Probate fraud and undue influence are two of the most common grounds for contesting a will or trust in Florida. Undue influence occurs when someone in a position of trust overpowers a vulnerable person’s free will and substitutes their own intentions for the maker’s, while probate fraud involves deception that causes a person to sign a document they would not otherwise have signed or that misrepresents the document’s contents. Both can void a will, a beneficiary designation, or an entire estate plan if proven in a Florida probate court.
I have spent years litigating these disputes, and they almost never look like the dramatic forgery you see on television. More often, the fraud is quiet. An elderly widow signs a new will three weeks before she dies, leaving everything to the home health aide who controlled her phone, her medications, and her checkbook. The signature is genuine. The notary was real. And yet the document does not reflect what she wanted. That gap, between a technically valid signature and a genuinely free choice, is where these cases live.
What Counts as Undue Influence Under Florida Law
Florida courts do not treat ordinary persuasion as undue influence. Adult children are allowed to ask a parent to remember them. A spouse is allowed to express preferences. The line is crossed when the influence becomes so coercive that it destroys the free agency of the person making the will. The classic Florida formulation, drawn from In re Estate of Carpenter (Fla. 1971), asks whether the influence amounted to “over-persuasion, duress, force, coercion, or artful or fraudulent contrivances” sufficient to destroy free will.
What makes Florida distinctive is that the law gives contestants a powerful procedural tool: a presumption of undue influence. Once a challenger establishes three foundational facts, the burden shifts to the person defending the will to prove the gift was legitimate.
The three elements that trigger the presumption are:
- A confidential relationship between the deceased and the alleged influencer. This can be a caregiver, an agent under a power of attorney, a guardian, a financial advisor, an adult child handling the parent’s affairs, or anyone in a position of trust and dependency.
- A substantial benefit received by that person under the will, trust, or transfer being challenged.
- Active procurement of the document by the beneficiary, meaning they were involved in bringing the will about.
On the third element, Florida courts look to the Carpenter factors when deciding whether someone “actively procured” a will. No single factor is required, and the list is not exhaustive, but courts weigh things like:
- The beneficiary’s presence when the will was executed.
- Their presence when the maker expressed a desire to make a will.
- Whether they recommended or selected the attorney who drafted it.
- Whether they knew the contents of the will before it was signed.
- Whether they gave instructions to the drafting attorney.
- Whether they secured the witnesses to the will.
- Whether they kept the executed will in their safekeeping after it was signed.
When these elements line up, the presumption arises. Under Florida Statutes section 733.107, the burden then shifts to the proponent of the will to come forward with a reasonable explanation for the active role in the transaction. This burden-shifting rule, codified after the Florida Supreme Court’s decision in Hack v. Janes, is one of the most important weapons a contestant has, because undue influence is rarely committed in front of witnesses. It happens behind closed doors, and the law accounts for that secrecy.
From Guardianship to Probate: Where Influence Often Begins
In Palm Beach County, many of the strongest undue influence cases trace back to a guardianship or a power of attorney that went unsupervised. A person is appointed to manage an aging parent’s finances, isolates that parent from the rest of the family, and then a new estate plan appears that funnels assets toward the person holding the keys. When that arrangement later surfaces in probate, the prior fiduciary relationship is not a defense. It is often the very confidential relationship that triggers the presumption. The transition from a lifetime guardianship dispute into a post-death probate fight is one of the most contested areas of Florida estate litigation, and the evidence from the guardianship phase frequently becomes the backbone of the will contest.
Probate Fraud: A Different Standard, Higher Proof
Fraud is conceptually distinct from undue influence, though the two are often pleaded together. Florida recognizes two flavors in the probate context:
- Fraud in the execution happens when a person is deceived about the nature of the document they are signing. They think they are signing a power of attorney or a deed, and it is actually a will. The signature is real, but the consent is not.
- Fraud in the inducement happens when a person knowingly signs a will, but they were lied to about facts material to its terms. A son tells his mother his sister has been stealing from her, the lie convinces her to disinherit the daughter, and the new will reflects that false belief.
To set aside a will for fraud in Florida, a contestant generally must prove that a false representation was made, that the person making the will relied on it, and that the misrepresentation caused the disposition. Florida courts require this be shown by the greater weight of the evidence in a will contest, though fraud allegations are scrutinized carefully because they accuse someone of deliberate deceit.
Forgery, the most extreme form, is its own ground. If the signature itself is not genuine, the will is void. These cases turn on forensic document examiners, the testimony of the attesting witnesses, and the formalities required by Florida Statutes section 732.502, which governs how a will must be signed and witnessed.
Lack of Testamentary Capacity Often Travels Alongside
Undue influence and fraud frequently appear next to a third claim: lack of testamentary capacity. Florida requires that the person making a will understand, in a general way, the nature and extent of their property, the natural objects of their bounty (their family), and the practical effect of the will. A diagnosis of dementia does not automatically void a will, because capacity is measured at the moment of signing, and a person can have a lucid interval. But cognitive decline and undue influence reinforce each other in court: the weaker the mind, the easier it is to overpower, and the lower the threshold for a finding that the will was procured rather than freely chosen.
The Evidence That Wins These Cases
These claims are won and lost on documentation. By the time the dispute reaches probate, the central witness, the person who made the will, has died. Everything depends on the paper trail and the people around them. Over the years, the records that consistently carry weight include:
- Medical and cognitive records from the months surrounding the signing, including hospitalizations, neurological evaluations, and medication lists that may have impaired judgment.
- The drafting attorney’s file and notes, which often reveal who called to set up the appointment, who sat in the room, and who relayed the instructions.
- Bank and financial records showing a pattern of transfers, account-name changes, or beneficiary designations that shifted in the influencer’s favor.
- Evidence of isolation, such as changed locks, intercepted mail, screened phone calls, or a sudden inability of other family members to reach the parent.
- Prior estate plans that were consistent for decades before an abrupt, last-minute change.
A sudden, dramatic departure from a long-stable estate plan, executed when the person was sick and dependent on the very beneficiary who gained the most, is the fact pattern that judges recognize. Each piece may be explainable on its own. Together, they tell a story.
How and When to Bring a Claim in Florida Probate
Timing is critical. In a formal Florida probate administration, an interested party who receives the statutory Notice of Administration generally has only three months from the date that notice is served to file objections to the validity of the will, the venue, or the jurisdiction of the court, under Florida Statutes section 733.212. Miss that window and the right to contest can be lost entirely. This deadline is far shorter than people expect, and it is the single most common reason valid contests never get heard. If you suspect a problem, do not wait.
A will contest is filed as a petition in the probate division of the circuit court where the estate is being administered. Palm Beach County estates are handled in the Fifteenth Judicial Circuit. Discovery, depositions of the drafting attorney and witnesses, and often dueling expert opinions on capacity follow. Florida also has a notable rule worth understanding: in terrorem clauses, the “no-contest” provisions common in other states, are unenforceable in Florida under section 732.517 for wills (and section 736.1108 for trusts). A beneficiary can challenge a suspicious will without forfeiting an inheritance they would otherwise receive, which removes a major deterrent that exists elsewhere.
Trusts and Non-Probate Transfers Are Fair Game Too
Undue influence and fraud are not limited to wills. The same principles reach revocable trusts, deeds, joint-account designations, and beneficiary forms on life insurance and retirement accounts. Because so much wealth now passes outside of probate through these instruments, much of the actual fight happens over trust amendments and last-minute account changes rather than the will itself. Florida’s burden-shifting presumption applies to these transfers as well.
If you are weighing a challenge, it helps to understand how probate works more broadly first.

Why These Cases Are Worth Fighting
People sometimes ask whether contesting a will is worth the cost and the family conflict. There is no universal answer. But when a vulnerable person’s last wishes were hijacked, the harm is not only financial. It is the erasure of decades of intent in the final weeks of a life. Florida’s law, with its burden-shifting presumption, its rejection of no-contest penalties, and its careful treatment of capacity, is structured to give families a real chance to prove what happened. The cases are fact-intensive and they reward early, organized investigation. If something about a loved one’s final estate plan does not sit right, the clock under section 733.212 is already running, and the time to speak with a probate litigator is now.

Frequently Asked Questions
What is the difference between undue influence and probate fraud in Florida?
Undue influence happens when someone in a position of trust coerces a vulnerable person into making a will or transfer that reflects the influencer’s wishes rather than the maker’s own free will. Probate fraud involves deception, either tricking the person about what they are signing (fraud in the execution) or lying about material facts to induce a particular disposition (fraud in the inducement). Undue influence focuses on coercion and lost free agency; fraud focuses on a false statement that was relied upon. They are often pleaded together in the same will contest.
How does Florida's presumption of undue influence work?
Under Florida law and section 733.107, a presumption of undue influence arises when a challenger proves three things: the beneficiary had a confidential relationship with the deceased, received a substantial benefit, and was actively involved in procuring the will or transfer. Once those elements are shown, the burden shifts to the person defending the document to provide a reasonable explanation for their active role. Courts use the Carpenter factors, such as who selected the attorney and who was present at signing, to evaluate active procurement.
How long do I have to contest a will in Florida?
If you are served with a formal Notice of Administration, you generally have only three months from the date of service to file objections challenging the validity of the will, under Florida Statutes section 733.212. This deadline is short and strictly enforced, so missing it can permanently bar your claim. Because investigation takes time, you should consult a probate litigation attorney as soon as you suspect a problem rather than waiting for the deadline to approach.
Will I lose my inheritance if I challenge a suspicious will in Florida?
No. Florida does not enforce no-contest (in terrorem) clauses. Under section 732.517 for wills and section 736.1108 for trusts, a provision that tries to disinherit a beneficiary for challenging the document is unenforceable. This means you can bring a good-faith undue influence or fraud claim without forfeiting an inheritance you would otherwise be entitled to receive, which is a meaningful difference from many other states.
Can undue influence or fraud be used to challenge a trust or beneficiary designation, not just a will?
Yes. The same legal principles apply to revocable trusts, trust amendments, deeds, joint bank accounts, and beneficiary designations on life insurance and retirement accounts. Because so many assets now pass outside of probate, much of the actual litigation involves these non-probate transfers. Florida’s burden-shifting presumption of undue influence extends to these instruments when a confidential relationship, a substantial benefit, and active procurement are present.
