Does the property service contract need to be ratified by handprint?

If the parties conclude a book contract by contract, they shall sign or seal it. If the parties press their fingerprints on the contract, the people's court shall determine that it has the same legal effect as the signature or seal.

According to the relevant laws and regulations of our country, if the parties conclude a contract in the form of a contract, the contract will be established when both parties sign or seal it.

If the party concerned has no writing ability, if it is written by someone else, it should be in line with the wishes of the party concerned, and the party concerned is required to press the handprint to show that he has known and agreed to the event.
