Duly notarized is a phrase used to refer to a document that has been officially signed and witnessed by a Notary Public. This process officially recognizes the authenticity of documents, seals them with an official stamp, and verifies the signatures of parties involved. It is an important way to validate the legitimacy of official documents and confirm that all relevant parties have agreed to the contents of the document. Duly notarized documents offer all concerned parties peace of mind and assurance that the document stipulated in it has undergone the required authentication process.
