Iowa Code Title XV. Judicial Branch and Judicial Procedures [Chs. 595-686] § 633.172. Will--waiver of bond

1. When, by the terms of the will, the testator has directed or expressed the desire that no bond shall be required, such direction or expression shall be construed to be a waiver of the posting of a bond by the fiduciary for all purposes, and no bond shall be required unless the court for good cause finds it proper to require one; if no bond is initially required, the court may nevertheless, for good cause, at any subsequent time require that a bond be given.

2. Unless otherwise required by the instrument creating the relationship, or by order of court, bank and trust companies shall not be required to provide any bond.
