How can you cash a check in someone else name?

To cash a check in someone else's name, you typically need their endorsement on the back of the check, which means they must sign it. Some banks may also require the person whose name is on the check to be present with valid identification. Alternatively, you can ask the check writer to cash it themselves or deposit it into their account, then give you the cash. Always check with the specific bank for their policies, as they can vary.
