Acknowledgements and Jurats are the two most common notarial certificates.
Jurat- Is used when the signer is swearing to the validity of the content of a document and requires a notary to administer an oath or affirmation to the signer.
Acknowledgement-Is used to verify the identity of a signer and confirm that they are the person who signed the document.
