Hello. A Notary cannot choose what notarial act is appropriate for a document. If the Notary is uncertain what notarial act is needed, the Notary should ask the signer what type of notarization they want and let the signer choose. If the signer is not certain, the agency that issued or will received the document should be contacted for instructions.
A notary public can make a copy of your document and certify it as being a true copy of the original. Also, you can make online copy here. You may request as many certified copies as you wish, which may be a good idea in the event you are dealing with, or applying to, more than one body or agency.
A jurat is used when the signer is swearing to the content of the document. The notary must administer an oath or affirmation to the signer in order to complete the jurat. A jurat also requires that the signer signs in the presence of the notary.
One of the most important duties of the Notary is to administer oaths and affirmations, which are solemn promises of truthfulness made by a signer, witness, or new office-holder. An oath is a promise to a deity and an affirmation is a pledge on one's personal honor.
