To notarize something means to have a document or signature verified by someone authorized to authenticate documents, administer oaths, and perform other legal formalities.

This person is known as a Notary Public.

When a document is notarized, the notary public confirms the identity of the person signing the document, witnesses the signing, and applies a seal or stamp to the document to certify that the signature is authentic and that the document has been properly executed.

Before a death, a person's Last Will and Testament may need to be notarized in order to prove its validity.

After a death, notarization is needed to officially transfer ownership of property from a deceased person to Heirs or Beneficiaries. They will need to sign legal documents and notarization may be required to certify that the signatures are authentic.

Notarization helps prevent fraud and ensures that the wishes of a deceased person, as outlined in their will or other legal documents, are carried out.
