A notarized document is a legal paper that has been verified by a notary public, an official authorized to witness signatures and certify the authenticity of documents. This process helps prevent fraud and ensures that the parties involved understand the contents of the document. Common examples of notarized documents include wills, contracts, and power of attorney forms. To notarize a document, the signer must appear in person before the notary public and provide valid identification. The notary then signs and stamps the document, indicating that it has been properly witnessed. This added layer of verification can be crucial in legal matters, as notarized documents are often required by courts and other institutions.
