Iowa Code § 558.1
All instruments containing a power to convey, or in any manner relating to real estate, including certified copies of petitions in bankruptcy with or without the schedules appended, of decrees of adjudication in bankruptcy, and of orders approving trustees' bonds in bankruptcy, and a jobs training agreement entered into under chapter 260E between an employer and community college which contains a description of the real estate affected, shall be held to be "instruments affecting real estate". An instrument affecting real estate, when acknowledged or certified and recorded as in this chapter prescribed, cannot be revoked as to third parties by any act of the parties by whom it was executed, until the instrument containing such revocation is acknowledged and filed for record in the same office in which the instrument containing such power is recorded, except that uniform commercial code financing statements and financing statement changes as provided in chapter 554 need not be thus acknowledged.
