The "Electronic Signature Law" clearly stipulates the scope of application of electronic signatures: For contracts or other documents, documents and other documents in civil activities, the parties may agree to use or not use electronic signatures and data messages. If the parties agree to use electronic signatures or data messages for documents, their legal validity shall not be denied simply because they are in the form of electronic signatures or data messages. The provisions of the preceding paragraph do not apply to other situations involving personal relationships such as marriage, adoption, inheritance, etc., or involving the cessation of heating, water supply, gas supply and other public utilities, or other situations stipulated by laws and administrative regulations.

In essence, the national legislative body is constantly exploring and improving the scope of application of electronic signatures. In 2019, the "Electronic Signature Law" was revised for the second time, allowing legal documents such as house sales contracts in the real estate transaction market. Use electronic signature. The implementation of this measure has further enhanced the activity of the real estate transaction market, improved work efficiency, and brought convenience to the majority of participants.
