How can I challenge a will that leaves biological children out in favor of stepchildren? - Florida
The Short Answer
In Florida, a parent generally can leave biological children out of a will—but you may be able to challenge the will if it was the product of undue influence, fraud, duress, or mistake, or if it is otherwise invalid. The key is that the issue is usually not “unfairness,” but whether the will reflects the decedent’s true, voluntary intent under Florida law.
What Florida Law Says
Florida does not automatically guarantee an inheritance to adult children when a valid will exists. So, a will that favors stepchildren over biological children is not automatically invalid. A will contest typically focuses on whether the document (or specific gifts in it) was improperly obtained—such as through undue influence or fraud—or whether the will is invalid for other legal reasons.
If you believe the stepchildren (or someone acting for them) pressured, manipulated, or deceived the decedent into changing the estate plan, Florida law provides a direct basis to attack the will (in whole or in part).
The Statute
The primary law governing this issue is Fla. Stat. § 732.5165.
This statute establishes that a will (or any part of it) is void if its execution was procured by fraud, duress, mistake, or undue influence, while allowing the remainder to stand if it was not improperly procured.
Florida law also addresses how proof works in a will contest: Fla. Stat. § 733.107 explains burdens of proof in contests and recognizes that, in certain situations, a presumption of undue influence can shift the burden under Florida evidence rules.

Why You Should Speak with an Attorney
While the statute provides the general rule, applying it to your specific situation is rarely simple—especially when the will benefits stepchildren and cuts out biological children, which can raise questions about family dynamics, caregiving, isolation, and control. Legal outcomes often depend on:
- Strict Deadlines: Will contests are time-sensitive, and waiting too long can limit your options—sometimes permanently—depending on where the estate is in the probate process.
- Burden of Proof: Under Fla. Stat. § 733.107, the estate can establish prima facie validity through execution/attestation, and then the contestant must prove the legal grounds (like undue influence or fraud). That typically requires records, witness testimony, and careful legal framing.
- Exceptions and “gray areas”: Not every “unfair” will is illegal. And not every close relationship is undue influence. Whether a presumption applies, what evidence is admissible, and whether only part of the will can be voided under Fla. Stat. § 732.5165 are issues that can make or break the case.
Trying to handle this alone can lead to missed deadlines, damaging admissions, or a record that’s too weak to win—even if something improper happened.
