D.C. Code § 14-501: Proof of record.

An exemplification of a record under the hand of the keeper of the record, and the seal of the court or office where the record is made, is good and sufficient evidence to prove a record made or entered in any State, territory, commonwealth or possession of the United States. The certificate of the person purporting to be the keeper of the record, accompanied by the seal, is prima facie evidence of that fact.
