Is the signature typing of tripartite agreement valid?
Invalid. Because according to Article 490 of the General Principles of Civil Law of People's Republic of China (PRC), if the parties conclude a contract in the form of a contract, the contract is established when the parties sign and seal it or fingerprint it, and the signature of the contract must be signed or sealed by themselves, so the typing of the signature of the tripartite agreement is invalid. Tripartite agreement means that an agreement needs three participants.
