Yes, if both parties conclude a contract in writing, the contract will be established as long as both parties sign or seal it. In real life, we can see that many legally binding contracts have no riding seal or page number, which has little influence on both parties. The riding seal means that the official seal should be covered on the middle seam of two foldable pages. The significance of the existence of the riding seal is to prevent possible risks, prevent possible problems such as changing the contents of the contract, and avoid unnecessary disputes and disputes. However, there is no law that stipulates that the contract should be stamped with the riding seal or the riding seal must be aligned, so the legal effect of the contract cannot be denied. The reason why we put an extra seal on the contract is to prevent more important documents from being changed at will.

After the receipt is stamped with the riding seal, you can see that the riding seal is restored to the original seal when the whole contract is launched. The other party cannot arbitrarily change the contents of the contract that has been concluded, nor can it deny the contents of the contract. This can avoid the trouble or loss caused by the other party's modification or disapproval of the contract. The main purpose of the riding seal is to avoid the change of the contents of the contract due to the change of the inside page of the contract, which has no effect on the effectiveness. The law does not stipulate that the contract must be stamped with a riding seal.
