A Notary Public is a public official authorized to witness the signing of important documents, verify the identity of signers, and administer oaths. Their primary role is to prevent fraud by ensuring that the individuals signing documents are who they claim to be and that they are doing so willingly. Notaries often handle documents like wills, contracts, and property deeds. They may also provide services such as certifying copies of documents and taking affidavits. The requirements to become a notary vary by state or country, but typically include passing an exam and undergoing a background check.
