Be sure you know the difference and which one you need to for your documentation.
Informational excerpt from Michigan Secretary of State:
Jurats
Jurat notarizations are required for transactions where the signer must attest to the content of the document, such as all affidavits and pleadings in court. It is a certification on an affidavit declaring when, where and before whom it was sworn. In executing a jurat, a notary guarantees that the signer personally appeared before the notary, was given an oath or affirmation by the notary attesting to the truthfulness of the document, and signed the document in the notary's presence. It is always important that the notary positively identify a signer for a jurat, as s/he is certifying that the signer attested to the truthfulness of the document contents under penalty of perjury. However, jurat notarizations do not prove a document is true, legal, valid or enforceable.
An example of a "jurat" is as follows:
Subscribed and sworn to by _________________ before me on the _____ day of _______ , _______.
Signature_________________________________
Printed name_____________________________
Notary public, State of Michigan, County of _________________
My commission expires_______________________
If no other wording is prescribed in a given instance, a notary may use the following language for an affidavit or deposition: Do you solemnly swear that the contents of this affidavit (or deposition, document, etc.) subscribed (signed) by you are correct and true, so help you God? Or, do you solemnly, sincerely and truly declare and affirm that the statements made by you are true and correct? When administering oaths, parties should raise their right hands. The left hand may be used in cases of disability.
Acknowledgments
Unlike a jurat (which requires a sworn oath), an acknowledgment is to merely confirm the identity of the document signer and acknowledge that they signed the document. If the document was signed outside the notary's presence, the document signer must make a personal appearance before the notary to confirm it is their signature prior to the document being notarized. Again, there is no exception to the requirement of a personal appearance before the notary.
The acknowledgment notarization is not part of the document, and it does not affect its validity. Typically, they are executed on deeds and other documents that will be publicly recorded by a county official.
An example of an "acknowledgment" is as follows:
Acknowledged by _________________ before me on the _____day of _______ , _________
Signature____________________________________
Printed name________________________________________
Notary public, State of Michigan, County of _________________
My commission expires_______________________
