Jurat vs. Acknowledgment: What's the Difference?

These are the two most common notarial acts, and which one a document needs depends on what the document is, not on personal preference. An acknowledgment confirms that the signer appeared before the notary and acknowledged that they signed the document (or are about to) willingly — no oath is involved, because the notary isn't certifying the document's contents are true, only that the named signer really is who they claim to be. A jurat requires the signer to take an oath (or affirmation) that the document's contents are true, and — unlike an acknowledgment — the signer must sign in the notary's actual presence, not beforehand.

Which Documents Use Which

Getting this wrong on the notarial certificate — the wording block the notary fills in — is a real, common reason a document gets rejected by a county recorder or receiving agency, since the certificate language legally represents which act actually happened.
