Two names can be written in the lease contract. Cooperation can protect the rights and obligations of both parties by signing a contract, but the premise is that both parties need to sign and seal the contract before it can take effect. For the contracting party, it can be one person or two people. If it is signed by two people, it means that if there are any problems and disputes in the future cooperation process, two people need to share the responsibilities and obligations, and the responsibility cannot be shirked to one of them.

According to the relevant provisions of the law, the contract is invalid under any of the following circumstances:

1. One party enters into a contract by means of fraud or coercion, which harms the national interests;

2, malicious collusion, damage the interests of the state, the collective or the third party;

3. Covering up illegal purposes in a legal form;

4, damage the public interests;

5. Violation of mandatory provisions of laws and administrative regulations.

Matters needing attention in the lease contract are:

1. Ask the landlord to issue the original and one copy of the real estate license and the landlord's ID card, and sign the contract after verification;

2. Write clearly the indoor facilities in the contract, including furniture and household appliances. If decoration is needed, it should also be indicated in the contract to avoid unnecessary disputes when renting in the future;

3. Write down the terms of the house rent, and indicate that during the lease period, Party A shall not charge any extra fees in any name.

To sum up, the rights and obligations of both parties can be guaranteed by signing a contract, but the premise is that both parties need to sign and seal the contract before it can take effect. The signatory can be one person or two people. If it is signed by two people, it means that if there are any problems and disputes in the future cooperation process, two people need to share the responsibilities and obligations, and they can't pass the buck to one of them.
