A notary public is a licensed professional authorized to administer oaths, witness signatures, and perform other official functions such as affirming the authenticity and validity of legal documents. Notary public services are used to help individuals and businesses authenticate important documents and transactions, such as contracts, deeds, and powers of attorney. In addition to verifying the identity of signers, notaries also ensure that the documents are signed voluntarily, without duress or coercion. 

Notary public services are typically provided by attorneys or individuals who have undergone specific training and certification. Notary publics may also offer additional services such as fingerprinting, document preparation, and legal advice. The use of notary public services can provide assurance and security in legal transactions and can be essential in ensuring that legal documents are binding and enforceable.
