How long is a cashier's check good for?

A cashier's check does not have an expiration date and is guaranteed by the issuing bank until the check is paid. The funds of a cashier's check generally must be turned over to the state's unclaimed property custodian after a period of time, according to the state's abandoned property laws.

The responsibility for covering a cashier's check is held by the bank, and it is drawn from the bank's funds, as opposed to personal checks where the customer is responsible for covering the funds when the check is cashed. Cashier's checks feature improved security features to prevent fraud and are commonly used in real estate transactions.
