Iowa Code § 633A.2207: Combination of trusts.

1. A trustee, without approval of court, may combine two or more trusts with substantially similar beneficial interests unless the trust is a court reporting trust.

2. On petition by a trustee or beneficiary, the court may combine two or more trusts, whether or not the beneficial interests are substantially similar, if the court determines that administration as a single trust will not defeat or significantly impair the accomplishment of the trust purposes or the rights of the beneficiaries.

3. Where the court orders the combination of two trusts that are not essentially identical, the court shall include in its order a finding as to which trust provisions control.
