Legal analysis: Under normal circumstances, the contract signer is not necessarily the legal representative. Even if the signer of the contract is not the legal representative, the contract is still legally binding. The key to the legal effect of a contract is usually the seal of the contract. As long as the signatory is authorized by the legal representative to sign the contract, obtains the legal representative's power of attorney, and signs the contract in the name of the legal representative within the authority of the agency.
