An acknowledgment is one of the most common notary certificates attached to a document. It indicates that the signer understood the purpose of the document, signed voluntarily, and the notary verified the ID and awareness of the signer. The signer did not make any sworn statement regarding the truth or accuracy of the contents of the document.
Best Practice, Sign in Notary Presence
It is best practice to sign the document in front of the notary, but is not required for an acknowledgment. If the signer has already signed the document, the notary must ask the signer to confirm that he/she signed the document, and the notary should compare the document signature with the signature on the photo ID.
Acknowledgments are attached to documents including real estate deeds, powers of attorney, living wills, contracts, leases, agreements, permission approvals, releases, settlements and assignments.
