Does the document need to be signed in notarys presence?
Not necessarily. A document requiring an acknowledgment does not need to be signed in front of the notary. The signer must confirm to the notary that he/she did freely sign the document. A jurat, on the other hand, DOES need to be signed before the notary. A jurat will contain the wording “subscribed (signed) and sworn to before me. . .” When in doubt, wait and sign the document before the notary.
