The individual sending money does not have to sign a cashiers check. The person who cashes or deposits the check must sign it when she does so. The bank analyses the account and fills out any documentation required to pay money with a cashiers check.
A cashier’s check is one of the safest and most reliable methods of sending and receiving money. Instead of drawing money from a personal account, the money is taken from the bank’s funds. Once the recipient signs and cashes or deposits the check, the bank deducts the amount from the person’s account.
