When signing a contract, the seal indicates the approval of the contract. When the contract has multiple pages, if only the last page is stamped, the first page is blank, and it is easy for both parties to replace the blank page, causing unnecessary trouble. Stamping the riding seal can prevent page change. How to cover the riding seal? First of all, you should sew up all the seams in your home so that every page has a red stamp. Secondly, the riding seal should be covered on the right side of the contract, not on the left side, because if it is bound on the left side, it will be easily covered after binding. If an individual signs the contract, the handprint of the riding seam can be held back, or it can be signed by the riding seam to maintain the integrity of the contract. Finally, it is particularly important to note that whether stamping or pressing fingerprints, the stamping or fingerprints should overlap with the text.
