Yes, but the branch company must be authorized by the head office to sign the contract, because the branch company cannot bear legal responsibility without a legal person. Article 3 1 of the Company Law stipulates that "a branch does not have the qualification of an enterprise legal person, and its civil liability shall be borne by the company", but in judicial practice, the third party chooses to be borne by the branch or the company, or jointly by the branch and the company. Because the branch (unincorporated organization) has certain group property, which constitutes certain responsibility ability, but its property is not completely independent and its responsibility ability is not complete, so its superior legal person generally bears supplementary responsibility.
