R 4542.Proof of foreign records and documents
Article 45. Evidence · Last amended 1972 · Last verified July 21, 2026
Full Text of CPLR 4542
Plain-English Summary
Records kept by a foreign government raise a harder authentication problem than domestic records: New York courts have no direct way to verify a foreign official's signature or authority. CPLR 4542 solves it with a chain of certification that ends with someone the court can trust. A foreign official record can be proven through an official publication of it, or through an attested copy backed by a final certification vouching for the genuineness of the attesting official's signature and position, a certification that itself may need to pass through a chain of other foreign officials before reaching the final certifier.
That final certification typically comes from a U.S. diplomatic or consular officer stationed in the foreign country, or from that country's own diplomatic or consular official assigned to the United States. Subdivision (b) also gives the court flexibility: for good cause, and where every party has had a reasonable chance to check the documents' authenticity and accuracy, the court can admit an attested copy without the final certification, or allow the record to come in as a certified summary.
Subdivision (c) addresses the negative case, proving that a foreign record does not exist. A written statement that a diligent search turned up no record of a specified kind, authenticated the same way as a copy would be, is admissible to prove the records contain no such entry.
Frequently Asked Questions
How do I authenticate a foreign country's official record for a New York court?
You need an official publication of the record, or an attested copy backed by a final certification of the attesting official's signature and position, usually from a U.S. or foreign consular officer.
Can a court admit a foreign record without the full certification chain?
Yes, for good cause and where all parties had a fair chance to check the documents' authenticity, the court may admit an attested copy without final certification or allow a certified summary instead.
How do I prove that a search of foreign records found nothing?
A written statement, authenticated the same way as a certified copy, that a diligent search found no record of a specified kind is admissible to prove the absence of that record.
Who can provide the final certification for a foreign record?
A U.S. secretary of embassy or legation, consul general, consul, vice consul, or consular agent can provide it, as can a diplomatic or consular official of the foreign country assigned to the United States.
Does the certifying chain always run through a single official?
No, the final certificate may relate directly to the attestation or may sit at the end of a chain of certificates from other foreign officials vouching for each other's signature and authority.
