The person who cashes or deposits the check must sign it at the moment of cashing or depositing it. The bank analyzes the account and fills out any documentation required to pay money using a cashier's check. Before giving you the money, the bank will also require proof of identity and address. You must present a valid photo ID (such as a driver's license) before you can receive the check. Check writing instructions are printed on the back of the check. These instructions include the name and address of the account holder, the number of the checking account, and whether the check is payable in full or payable on demand. If the check is payable in full, the account owner signs the back of the check. If the check is payable on demand, the account owner stamps "S/D" (signature demanded) instead. Cashiers checks are used when there is not enough money in the account to cover the check. The bank may ask for additional identification or evidence of ability to pay before cashing the check. If the check does not clear the bank after several days, you should contact the bank by phone or online request that the check be returned. In some cases, if the check was written for more than $10,000 it may need to be signed by an officer of the company.
