A cashier's check is a type of payment instrument issued by a bank, guaranteeing the amount specified on the check. Unlike personal checks, which depend on the account holder's available funds, a cashier's check is backed by the bank's own funds, making it a secure form of payment. It is often used for large transactions, such as buying a car or a house, where the seller requires assurance that the payment will not bounce. To obtain a cashier's check, a customer must visit their bank and provide the necessary funds, along with a fee for the service. The bank then issues the check, which includes the bank's name, the amount, and the payee's information. This check can be deposited or cashed by the payee, providing a reliable way to complete financial transactions.
