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 ensures that the person signing the document is who they claim to be and that they are doing so willingly. Notarization adds a layer of trust and can be required for various legal transactions, such as real estate deals or contracts. The notary public typically stamps the document with a seal and includes their signature, indicating that the notarization has taken place. This makes the document more credible and can help prevent fraud. Common examples of notarized documents include wills, power of attorney, and affidavits.
