Undue influence means someone pressured a settlor until the trust reflected that person’s wishes, not the settlor’s own. Leslie V. Marenco is the lawyer responsible for this page. Trust Counsel, PL is located in Coral Gables, Florida, and we serve clients in Florida.<\/p>\n

What undue influence means in a Florida trust<\/h2>\n

Undue influence is pressure that overcomes a person’s free will. The settlor is the person who created the trust. When undue influence works, the trust says what someone else wanted, not what the settlor wanted.<\/p>\n

Undue influence is different from two other claims. Lack of capacity asks whether the settlor was mentally able to make the trust. Under \u00a7 736.0601<\/a>, the capacity needed to create or change a revocable trust is the same as the capacity needed to make a will. Fraud, duress, and mistake are separate grounds too. Each needs its own proof, so know which one fits your facts.<\/p>\n

Who carries the burden? Under \u00a7 736.0207<\/a>, the contestant, meaning the person challenging the trust, must prove the grounds for invalidity. Florida also has a presumption that can shift that burden in some cases.<\/p>\n\n

The Florida rules: \u00a7 736.0406 and \u00a7 733.107<\/h2>\n

A trust procured by undue influence can be void. Under \u00a7 736.0406<\/a>, if fraud, duress, mistake, or undue influence procured the creation, amendment, or restatement of a trust, that trust or the part procured that way is void. The rest survives if it is valid for other reasons.<\/p>\n

The presumption appears in \u00a7 733.107<\/a>. Under Fla. Stat. \u00a7 733.107<\/a>, in any transaction or event to which the presumption of undue influence applies, the presumption implements public policy against abuse of fiduciary or confidential relationships. It shifts the burden of proof.<\/p>\n

Not every change is improper. Unless the trust itself says it is irrevocable, the settlor may revoke or amend it under \u00a7 736.0602<\/a>, though this rule does not apply to a trust created under an instrument signed before Florida’s trust code took effect. A change alone does not prove pressure. You need facts showing the settlor’s own wishes were overcome.<\/p>\n

Confidential relationships and active involvement<\/h2>\n

A confidential relationship exists when the settlor relied on someone to manage their affairs or look after them. Common examples include a caregiver, a person holding a power of attorney, or a close family member who handles bills and daily money matters.<\/p>\n

A relationship alone is rarely the whole story. Pressure often shows up as active involvement. The person may have picked the drafting attorney, scheduled the meeting, passed along instructions, or been present when the settlor signed. The person may also receive a large share of the trust.<\/p>\n

Consider a simple case. An adult child drives a parent to every meeting with the lawyer, chooses that lawyer, and then inherits most of the trust. That pattern is what people look for. It is not proof on its own, but it gives a reason to look closer.<\/p>\n

Factors that often matter in these cases<\/h2>\n

Courts look at the full pattern of facts. No single fact usually decides the case. Several factors often appear together in these disputes.<\/p>\n

The settlor’s condition matters most. Age, illness, dependence on others, isolation from friends or family, and cognitive decline can all make a settlor more open to pressure. A settlor who was sick or confused when the trust changed presents a different picture from one who was healthy and independent.<\/p>\n

Timing and change matter too. A sudden departure from a long-standing plan can stand out, especially if it lines up with a new caregiver or a new decision-maker. Secrecy is another common factor. So is a benefit that seems unnatural, such as a gift that cuts out children the settlor always named.<\/p>\n

Put these together. One odd change might have an explanation. A pattern of isolation, secrecy, and a new large benefit to the person in charge is harder to explain away.<\/p>\n

What evidence supports an undue influence claim<\/h2>\n

The strongest evidence is usually a paper trail. It shows who did what, and when. Start with the trust documents. Prior versions of the trust or will show what the settlor wanted before the change. Drafts, emails, texts, and calendar entries can show who asked for changes and who met with the drafting attorney.<\/p>\n

Financial records add another layer. Bank and account statements can show transfers, new signature authority given to one person, or payments that moved money toward a beneficiary. Records showing control of accounts often tell a clear story when placed on a timeline.<\/p>\n

Build that timeline. List each trust change, meeting, hospital stay, and transfer in date order. Note who was present. Gaps in the record can matter as much as the records themselves.<\/p>\n

Keep originals safe. Don’t edit, delete, or forward documents to “clean them up.” Lost or altered evidence can hurt your position more than the change you’re challenging.<\/p>\n

Witness testimony and medical records<\/h2>\n

Witnesses and medical records often fill in what documents cannot. Witness testimony describes what people saw and heard. Medical records show what the settlor’s body and mind were doing at the time.<\/p>\n

Possible witnesses include the drafting attorney, people who saw the signing, bank staff, caregivers, friends, neighbors, and relatives who saw the relationship up close. A witness who saw the settlor without the beneficiary present can be especially useful. Testimony carries more weight when it matches the documents.<\/p>\n

Medical records can include physician notes, hospital charts, care-facility records, and medication lists. They can show diagnoses, cognitive assessments, and dates that line up with the trust change. A medical professional can help explain what those records mean.<\/p>\n

Request records early. Memories fade, and records take time to gather.<\/p>\n\n

Timing, deadlines, and first steps<\/h2>\n

Florida sets deadlines for trust contests, and they can start sooner than you expect. Under \u00a7 736.0207<\/a>, a contest to a revocable trust may not begin until the trust becomes irrevocable by its terms or at the settlor’s death, but this does not prohibit such an action by the guardian of the property of an incapacitated settlor. Under \u00a7 736.0604<\/a>, a contest to a trust that was revocable at death is barred if not started within the earlier of the chapter 95 time or six months after the trustee sends a copy of the trust and a required notice. Whether those rules fit your situation depends on the facts, so check the timing early.<\/p>\n

Mediation can be an option. The American Arbitration Association<\/a> describes mediation as a process that may resolve disputes faster than litigation. The Florida State Courts System ADR Resource Handbook<\/a> describes court-related mediation rules and confidentiality provisions that may apply.<\/p>\n

Start with these steps. Write down when the trust changed, who was present, who benefited, and the settlor’s condition at each point. Preserve documents, texts, and medical records now.<\/p>\n\n

Talking with a Florida trust litigation attorney<\/h2>\n

If you’re worried about a parent’s trust, you’re not alone in finding this hard. You may be juggling a loved one’s care, their paperwork, and family tension all at once.<\/p>\n

Maybe the trust changed months before a health decline. Maybe one sibling controls the accounts and won’t share statements. Maybe a relative received most of the estate, and you don’t understand why. Those are the situations where a short conversation can clear up what’s possible.<\/p>\n

Trust Counsel’s attorneys can serve individually as trustee or personal representative, and the firm advises and represents trustees, personal representatives and beneficiaries.<\/p>\n
