Plain-English Summary
A domestic official record can be proven through an official publication of it, or through a copy attested by the officer with legal custody (or a deputy), accompanied by a certificate confirming that custody. That certificate itself needs its own authentication, either from a judge of a court of record with the court's seal, or from another public officer with an official seal covering the district where the record is kept.
A foreign official record works similarly but needs a final certification of the attesting person's signature and position, which can come from a U.S. diplomatic or consular officer or a foreign diplomat accredited to the United States; the court can excuse the final certification for good cause shown and accept an attested copy or summary instead, once all parties have had a fair chance to check the record's authenticity, or if a treaty already covers the certification. Separately, a written statement that a diligent search turned up no matching record is itself admissible to prove that no such record exists, and nothing in this rule blocks proving an official record, or the absence of one, through any other lawful method.
Frequently Asked Questions
How is a domestic official record authenticated for trial?
Through an official publication of the record, or a copy attested by the officer with legal custody of it and accompanied by a certificate of that custody, itself authenticated by a court seal or another public officer's seal.
What about a record from a foreign country?
It generally needs a final certification of the attesting person's signature and position from a diplomatic or consular official, though the court can excuse that certification and accept an attested copy or summary for good cause shown, once the parties have had a fair chance to verify authenticity.
Can you prove that no record exists?
Yes. Rule 44(b) makes a written statement that a diligent search found no matching record admissible as evidence that no such record or entry exists.
