Party A is an individual and has signed it, while Party B is a company with only the official seal. Has the contract come into effect?
This contract shall come into effect after being signed and sealed. If only the seal is unsigned, the contract will not come into effect. Generally speaking, a contract is valid as long as it is the true intention of both parties. Without the seal, the validity of the contract itself cannot be denied. Unless otherwise specified, for example, a contract without seal is invalid, or a contract without company seal is invalid. In trading activities, signature and seal are the basic requirements of many laws.
