Legal analysis: The contract is valid without the riding seal. According to laws and regulations, a contract is concluded by the parties through consultation and takes effect after being signed or sealed by the parties. As long as the parties to the contract sign or seal the text of the contract, and the signature or seal meets the statutory requirements, if the contract has no riding seal, the validity of the contract will not be affected. However, under certain conditions, there is a greater risk that the inside page of the contract will be replaced without a cover, which will cause losses to one party of the contract and should be compensated.
