According to Article 3 of the Electronic Signature Law:
In civil activities, the parties may agree to use or not use electronic signatures and data messages in contracts or other documents, vouchers and other documents.
A document in the form of electronic signature or data message agreed by the parties shall not be denied its legal effect just because it is in the form of electronic signature or data message.
The provisions of the preceding paragraph shall not apply to the following documents:
(a) involving marriage, adoption, inheritance and other personal relationships;
(two) involving the transfer of rights and interests of real estate such as land and houses;
(three) involving the cessation of water supply, heating, gas supply, power supply and other public utilities services;
(4) Other circumstances in which electronic documents are not applicable as stipulated by laws and administrative regulations.
Legal electronic contracts need to meet certain legal conditions before they have evidence and probative force. The core of electronic contract lies in electronic signature, which must meet the four provisions of Article 13 of the Electronic Signature Law before it has legal nature. However, legal and effective electronic signature has the characteristics of anti-repudiation, anti-tampering, anti-counterfeiting and so on. Through technical means, as well as supporting services such as third-party storage and issuance of certificates, it is safer than traditional signing methods such as platform generation contract and email confirmation and online signing methods.
