Fla. Stat. § 736.1105

Unless the trust instrument or the judgment for dissolution of marriage or divorce expressly provides otherwise, if a revocable trust is executed by a husband or wife as settlor prior to annulment of the marriage or entry of a judgment for dissolution of marriage or divorce of the settlor from the settlor’s spouse, any provision of the trust that affects the settlor’s spouse will become void upon annulment of the marriage or entry of the judgment of dissolution of marriage or divorce and any such trust shall be administered and construed as if the settlor’s spouse had died on the date of the annulment or on entry of the judgment for dissolution of marriage or divorce.
