D.C. Mun. Regs. tit. 9, r. 9-3005
If there is a dispute between two (2) or more jurisdictions which claim the same abandoned property under § 126 of the Act (D.C. Code § 42-226), the provisions of this section shall be determinative.
If the owner's address does not appear on the records of the holder, the state of the holder's incorporation may take custody of the property until some other jurisdiction comes forward with proof of a superior right to custody of the property.
If the owner's address is known, the state or jurisdiction of the last known address of the owner shall have priority.
If the owner's address is in a jurisdiction that does not have an escheat or uniform disposition statute, then the state of the holder's incorporation shall take priority.
Each dispute shall be considered within thirty (30) days after it is presented.
