Is the contract riding seal stamped by Party A or Party B?

Legal analysis: either party can cover it. Legally speaking, there is no requirement, and both parties can choose freely. The purpose of affixing the riding nail stamp on the contract is to prevent one party from modifying the contract. There is no specific provision in the law on whether it is necessary to affix the riding nail stamp. Because both parties seal to confirm the establishment of the contract, and each party holds one copy, one copy held by both parties has the same legal effect as the other. In the contract, it is up to both parties to decide whether one company seals or two companies seal. Generally speaking, the party who stamps first will stamp the horse riding seal together, or both sides will stamp. 1, riding seal is generally used in more important documents. Because these documents are important, they are usually archived, and they are usually found in files, transfer letters of introduction or documents of other organizations and personnel departments. 2. As the name implies, the riding seal is pressed to the side seam when it is stamped. When the common official seal is stamped, it requires "riding on the moon", while the riding seal requires "riding on the seam", that is, the official seal should be evenly covered on the middle seam of two foldable sheets of paper, half of which should be kept as a stub and the other half as a voucher. When verifying, the two halves are opposite, and the official seal should be complete. 3. Like "steel seal", it has the function of preventing the page number in the document from increasing or decreasing, that is, it can see more or less pages, and can prevent tampering by hollowing out or adding pages to maintain the integrity of the document.
