Fla. Stat. § 737.206
A trust is void if the execution is procured by fraud, duress, mistake, or undue influence. Any part of the trust is void if so procured, but the remainder of the trust not so procured is valid if it is not invalid for other reasons. An action to contest the validity of all or part of a trust may not be commenced until the trust becomes irrevocable.
