Iowa Code § 554.9325: Priority of security interests in transferred collateral.

1. Except as otherwise provided in subsection 2, a security interest created by a debtor is subordinate to a security interest in the same collateral created by another person if:

a. the debtor acquired the collateral subject to the security interest created by the other person;

b. the security interest created by the other person was perfected when the debtor acquired the collateral; and

c. there is no period thereafter when the security interest is unperfected.

2. Subsection 1 subordinates a security interest only if the security interest:

a. otherwise would have priority solely under section 554.9322, subsection 1, or section 554.9324; or

b. arose solely under section 554.2711, subsection 3, or section 554.13508, subsection 5.
