Yes. If you buy a money order to send money to somebody you know or pay a bill, you will be asked to provide your signature on the front of the money order. It is important to check all the information on the money order before you sign. Do not sign the back of the form. This is where the payee will sign. When the recipient signs the back of the money order, this endorses the form before the order is cashed. Check out our guide above for a detailed explanation of how to fill out a money order.
