In terms of the validity of the contract, as long as both parties sign and seal, the contract will take effect and be legally binding, so the contract of electronic scanning or copying is also valid. If there is a dispute during the performance of the contract, the other party denies the validity of the contract and there is no other evidence to prove the contents of the contract, the court will generally not accept the fax. In this way, the other party will not be able to prove the true content of the contract, which is unfavorable to it. Article 10 The parties may conclude a contract in writing, orally or in other forms. If laws and administrative regulations stipulate that it should be in writing, it should be in writing. If the parties agree to use written form, it shall be in written form.
