Iowa Code Title XV. Judicial Branch and Judicial Procedures [Chs. 595-686] § 633A.3107. Effect of divorce or dissolution

1. If, after executing a revocable trust, the settlor is divorced or the settlor's marriage is dissolved, all provisions in the trust in favor of the settlor's spouse or of a relative of the settlor's spouse, including but not limited to dispositions, appointments of property, and nominations to serve in any fiduciary or representative capacity, are revoked by divorce or dissolution of marriage unless the trust instrument provides otherwise.

2. Unless the trust instrument provides otherwise, in the event the settlor and spouse remarry each other, the provisions of the revocable trust revoked by the divorce or dissolution of marriage shall be reinstated unless otherwise modified by the settlor, except for provisions in favor of a person who died prior to the remarriage which shall not be reinstated.

3. For the purposes of this section, “relative of the settlor's spouse” means a person who is related to the divorced settlor's former spouse by blood, adoption, or affinity, and who, subsequent to the divorce or dissolution of marriage, ceased to be related to the settlor by blood, adoption, or affinity.
