A notary public is a public official whose job mainly consists of authorising official documents, such as deeds, affidavits and civil marriage certificates. Notaries are considered part of the legal system, and their signature makes these documents legally binding. This is known as notarization. Because they are public officers, notaries can often be found in places like banks or post offices. Since documents must often be mailed after being notarised, the post office a very convenient place to have this service done.
Call your local post office and ask if they have a notary, since not all post offices do. Even if your local branch does employ a notary, take note of their hours, since they may not work all day or every day.
Make sure the notary can notarise the specific type of document you have. Not all notaries can perform the same functions.
Bring a picture I.D. and any other documents or items the notary asks you to bring. Find out what the fee is for the services you are receiving.
