A Notary's duty is to screen the signers of important documents for their true identity, their willingness to sign without duress or intimidation, and their awareness of the contents of the document or transaction. Some notarizations also require the Notary to put the signer under an oath, declaring under penalty of perjury that the information contained in a document is true and correct. Property deeds, wills and powers of attorney are examples of documents that commonly require a Notary. (2021, National Notary Assocaition)
