In this case, if Company A expressly authorizes Company B to sign a contract with Company C on its behalf, and both parties confirm and agree to this authorization relationship, the contract is valid.

In the laws of some countries/regions, an agent can enter into a contract on behalf of another person, provided that the agent has the authority to represent that person and the other party knows and agrees to this authorization relationship. Therefore, in this case, Company A can authorize Company B to sign a contract with Company C on its behalf.

However, when signing a contract, in order to avoid possible disputes, it should be clearly stated in the contract text that Company A is the principal, Company B is the agent, and Company B signs the contract with Company C on behalf of Company A. Contract authorization status. This helps ensure the validity of the contract and avoid disputes arising from unclear authorization relationships.

In short, as long as the agency relationship is clear and the authorization is stated in the contract, the contract is legal and valid.
