Electronic contracts have legal effect in written form and are effective. As a written contract, the electronic contract should be used as evidence, and the validity of the contract should be judged first. Electronic contracts need to meet the requirements for the effective establishment of contracts. According to relevant regulations, if a contract is concluded in the form of data message, and the recipient designates a specific system to receive the data message, the time when the data message enters the specific system is regarded as the arrival time.

Legal basis:

Article 13 of the Electronic Signature Law of People's Republic of China (PRC) stipulates that an electronic signature shall be regarded as reliable if it meets the following conditions at the same time;

(1) When the electronic signature production data is used for electronic signature, it belongs to the exclusive rights of the electronic signer;

(2) When signing, the electronic signature production data is only controlled by the electronic signer;

(3) Any changes to the electronic signature after signature can be found;

(4) Any changes to the content and form of the data message after signature can be found.

The parties can also choose to use electronic signatures that meet their agreed reliable conditions.
