The contract is valid only if it is stamped without signature and date. According to the law, if the parties conclude a contract in the form of a contract, the contract is established when both parties sign and seal it or press their fingerprints, so the contract can be signed or sealed. The content of the contract is agreed by the parties, and the date is not a necessary clause in the contract, so the absence of a date in the contract does not affect the validity of the contract.
