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.
A: No. Contracts for deed are private agreements between two parties. For example, a beginning farmer (the buyer) and a transitioning farmer (the seller) could enter into a contract for deed agreement. Generally, there is no bank or government agency involved in a contract for deed. Instead, the buyer makes regular payments directly to the seller according to the contract. One important feature of contracts for deed is that the seller keeps legal title to the land until the full contract for deed price is paid.
