Party B of the contract can write the names of two people. This means that the two people are both parties to the contract and generally bear joint and several roles in the performance of the contract. The law does not stipulate that the legal party to a contract can only be one civil subject, as long as they have reached a true agreement on the contract.

For example: Party B can sign a rental contract for two people. Two people *** share the right to use the rental house. If the landlord is only willing to sign with one person, it depends on the landlord's intention. If the contract is signed by one person, that person has the right to use the house. If the parties conclude a contract in the form of a contract, the contract is established when both parties sign, seal or fingerprint the contract. Before signing, sealing or fingerprinting, one party has performed its main obligations and the contract is established when the other party accepts it.
