Who has the legal right to void a check from a client?

The legal right to void a check typically belongs to the issuer of the check, which is the client who wrote it. They can void the check before it is cashed or deposited, often by notifying their bank or marking the check as void. Additionally, a bank may also have the authority to void a check under certain circumstances, such as if it is reported lost or stolen. However, once a check is cashed or deposited, the ability to void it generally ceases.
