Legal analysis: Generally speaking, a contract without the signature of the legal representative cannot be supported by law. According to China's company law, the legal representative exercises authority on behalf of the company. The performance of the legal representative in exercising his functions and powers lies in signing or sealing the contract to show that he is engaged in civil activities as a company. If the legal representative does not sign, the parties to the contract cannot be determined at this time. Therefore, the contract cannot be established at all, and the law will not support it.

Legal basis: Article 13 of the Company Law of People's Republic of China (PRC), the legal representative of the company shall be the chairman, executive director or manager as stipulated in the articles of association, and shall be registered according to law.
