A contract typically does not have to be notarized. A notary public (or simply notary) provides an acknowledgment that the signature appearing on the document is that of the person whose signature it purports to be.

A quitclaim deed has specific requirements that it must meet in order for it to be legally binding. It must note the names of the grantor and the grantee, and it must identify the property with its legal description, including the name of the county in which it is located.
