The document then reflects that someone’s wishes instead of the maker’s. Florida law treats a document procured this way as void, at least in the part that was affected. This guide explains undue influence florida cases in plain language, so you can see where you stand before you decide what to do.
What Undue Influence Means in Florida
The maker signs a document that really reflects another person’s wishes.
Florida lists undue influence beside fraud, duress and mistake as separate grounds. Fla. Stat. § 732.5165 says a will is void if its execution is procured by any of them. Fla. Stat. § 736.0406 applies the same rule to trusts.
People who are elderly, ill, isolated or dependent on a caregiver may be more open to pressure. Questions often start when a late change benefits the person who helped with daily care or handled the paperwork. Those facts do not prove wrongdoing by themselves. They are where a careful review usually begins. For the broader steps, read about how to contest a will in Florida.

The Presumption of Undue Influence Under Florida Law
In some situations, Florida law presumes undue influence. That presumption changes who has to prove what.
The statute ties the presumption to fiduciary or confidential relationships. It exists to stop abuse of those relationships. Once it applies, it shifts the burden of proof (Fla. Stat. § 733.107).
In practice, the person defending the document must answer with evidence. A presumption is a starting rule, not the final answer. The court still weighs all the proof and decides whether undue influence actually happened.
Will contests follow a similar pattern. The person offering the will must first show its formal signing and witnessing. After that, the person challenging it must prove the grounds for the challenge (Florida Probate Rule 5.275).
How Undue Influence Is Proven
Undue influence is usually proven with circumstantial evidence. Pressure seldom happens in front of witnesses, so the surrounding facts carry the weight.
These questions usually shape a case:
- Who arranged the meeting with the lawyer, and who attended the signing?
- Who gave the instructions for the new document?
- Did the maker get advice from someone who did not benefit?
- What were the maker’s health and mental state near the signing date?
- Did the change match earlier plans, or did it break from them?
- Who kept the original document or chose the witnesses?
Evidence worth preserving early includes:
- Medical and cognitive records from near the signing date
- Prior wills and trusts
- Emails and texts
- Bank and transfer records
- Witness accounts
A prior estate plan that shows steady intent can matter as much as the contested document. Heirs and other interested parties can also file a caveat with the probate court.
Wills Versus Trusts: How an Undue Influence Claim Differs
A will is challenged in probate court. A trust is challenged under the Florida Trust Code. The core evidence questions are similar, but the path and the deadlines differ.
- Wills: A will contest cannot begin before the person dies (Fla. Stat. § 732.518). Objections to a will’s validity must be filed on or before the date that is 3 months after the date of service of a copy of the notice of administration on the objecting person, or those objections are forever barred (Fla. Stat. § 733.212). Fla. Stat. § 733.212 reads: “(d) That persons who may be entitled to exempt property under s. 732.402 will be deemed to have waived their rights to claim that property as exempt property unless a petition for determination of exempt property is filed by such persons or on their behalf on or before the later of the date that is 4 months after the date of service of a copy of the notice of administration on such persons or the date that is 40 days after the date of termination of any proceeding involving the construction, admission to probate, or validity of the will or involving any other matter affecting any part of the exempt property.”
- Revocable trusts: A contest cannot begin until the trust becomes irrevocable by its terms or by the settlor’s death, except that a guardian of the property of an incapacitated settlor may bring such an action; if all of a revocable trust has been revoked, a contest of the revocation cannot begin until after the settlor’s death (Fla. Stat. § 736.0207).
- Trust notice bar: A trust contest can be barred six months after the trustee sends the trust copy and a required notice, if that comes earlier than the chapter 95 deadline (Fla. Stat. § 736.0604).
- Trustee notice: Within 60 days after learning an irrevocable trust exists, or after learning that a formerly revocable trust has become irrevocable, whether by the settlor’s death or otherwise, the trustee must notify the qualified beneficiaries (Fla. Stat. § 736.0813).
A revocable trust can change without court involvement. That makes the timing of each change and the surrounding facts especially important. Gather the documents early, because the clocks can run on short timelines.

What to Expect: Steps in an Undue Influence Matter
A matter usually moves from review to evidence, then to filing, discovery and resolution.
- Confidential review. The attorneys look at the document, the timeline of changes and the people involved.
- Evidence preservation. Records are requested, and written notice is given where it fits the facts.
- A revocation proceeding for a will may be brought by any interested person, including a beneficiary under a prior will, before final discharge of the personal representative, unless it is barred (Fla. Stat. § 733.109).
- Discovery. Parties exchange documents and take depositions.
- Resolution. The parties may negotiate, mediate or go to trial, depending on the record.
Each phase depends on the court’s schedule, the complexity of the record and whether the parties settle.
