But sometimes there is no other way than to borrow from a family member. Interest is a way for the lender to calculate money for the loan and offset the risk associated with the transaction. The most important feature of every loan is the amount of money that is borrowed, so the first thing you want to write on your document is the amount that may be in the first line. Follow by typing the name and address of the borrower and then the lender. In this example, the borrower is in New York State and asks to borrow $10,000 from the lender. Depending on the amount of money borrowed, the lender may decide to leave the authorized agreement in the presence of a notary. This is recommended when the total amount, plus interest, is greater than the maximum rate allowed for the small claims court in the parties` jurisdiction (normally $5,000 or $10,000).
