Development of the banknote began in the Tang Dynasty during the 7th century, with local issues of paper currency, although true paper money did not appear until the 11th century, during the Song Dynasty.
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. There is a requirement that some documents be notarized, such as a real property deed.
Signature of the grantor should be there in the form. In some states, signatures of both the grantor and the grantee are required. A public notary should verify the signature of the grantor. Generally, the grantor has to sign the deed in front of a public notary. A legal description of the property is a must.
