Iowa Code § 633D.3: Registration in beneficiary form — sole or joint tenancy ownership.

Only an individual whose registration of a security shows sole ownership by one individual or multiple ownership by two or more individuals with a right of survivorship, rather than as tenants in common, may obtain registration in beneficiary form. Multiple owners of a security registered in beneficiary form shall hold as joint tenants with rights of survivorship, tenants by the entireties, or owners of community property held in survivorship form and not as tenants in common.
