eSignature law in China
Electronic signatures are legally binding in mainland China under the Electronic Signature Law (2004, amended 2015 and 2019), where a reliable electronic signature equals a handwritten signature or seal.
Governing law: Electronic Signature Law of the People's Republic of China (2004, amended 2015, 2019) (2005)
China's Electronic Signature Law, in force since 2005 and amended in 2015 and 2019, provides that a reliable electronic signature has the same legal effect as a handwritten signature or a seal. A signature is "reliable" where the creation data is linked solely to and controlled by the signer at signing, and any alteration to the signature or the document after signing is detectable. Parties must agree to use electronic signatures. Electronic contracts and data messages are broadly recognised, and the Law works alongside the Civil Code's contract rules and the Electronic Commerce Law. Reliable signatures often rely on certificates issued by licensed electronic-certification service providers supervised by the relevant authorities; China's internet courts routinely accept electronic evidence.
