A notary service is a professional service provided by a notary public, who is authorized to verify the authenticity of signatures, administer oaths, and certify documents as true and valid.

Notaries can notarize various documents such as affidavits, powers of attorney, loan documents, wills, contracts, and deeds, among others. The specific documents that can be notarized may vary depending on local laws.

During the notarization process, the notary verifies the identity of the signer, ensures their willingness to sign, and confirms the document's contents. The notary then attaches their official seal or stamp and signs the document, indicating that the notarization has been performed.

Notarizing a document adds an extra layer of credibility and ensures its authenticity. Many legal and financial transactions, such as real estate transfers, require notarized documents to provide assurance that the signatures are genuine and the contents are accurate.
