In states where Notaries are prohibited from certifying copies of documents, there is an alternative procedure called a copy certification by document custodian. This procedure allows a person in permanent possession of an original document to sign a written declaration that a copy of it is identical to the original, and take an oath or affirmation before the Notary. The custodian’s signature is then notarized on the written declaration using jurat wording. In essence, a copy certification by document custodian is an affidavit signed and sworn to by the custodian with a jurat as the notarization. Remember, the custodian, not the Notary, guarantees that the copy is an authentic reproduction of the original.
