eSignature Legality in China
Electronic signatures have been legally recognized in mainland China since 2005, with a clear legal distinction between ordinary electronic signatures and the stronger "reliable electronic signature" standard that carries the same weight as a handwritten signature or company chop.

Governing Law
This page covers mainland China. Hong Kong, Macau, and Taiwan each have their own separate electronic signature legislation.
Electronic Signature Law of the People's Republic of China (ESL)
Enacted in 2004 and effective April 1, 2005, then amended in 2015 and 2019. Article 3 defines an electronic signature as data in electronic form, attached to or logically associated with a data message, used to identify the signer and indicate their approval of the message's contents.
PRC Civil Code, Article 469
Effective January 1, 2021, the Civil Code reinforces the ESL by explicitly recognizing electronic data interchange, emails, and electronic signatures as valid forms of contract, on equal footing with paper.
Ordinary vs. Reliable Electronic Signatures
This distinction is the most important thing to understand about Chinese law:
Ordinary Electronic Signatures
typed names, scanned signature images, and similar low-friction methods. Suitable for lower-risk, informal transactions, but carry a lighter evidentiary weight if challenged.
Reliable Electronic Signatures
the standard the ESL treats as legally equivalent to a handwritten signature or company seal (chop). To qualify as "reliable," a signature must meet all of the following:
- The signature creation data is exclusively owned and controlled by the signer at the time of signing
- Any subsequent alteration to the signature or the associated document is detectable
- All parties consent to using electronic signatures for the transaction
In practice, courts are more likely to treat a signature as reliable if it's certified by an Electronic Certification Services Provider pre-approved by Chinese regulators (the Cyberspace Administration of China or the Ministry of Industry and Information Technology). If the parties use a provider that isn't pre-approved, the burden of proving reliability falls on the parties themselves.
When Chinese eSignatures May Not Be Accepted
The ESL specifically excludes:
- Documents relating to personal relationships, including marriage, adoption, and inheritance
- Real estate and other real property transfer documents
- Documents relating to termination of public utility services (water, heat, gas, electricity, etc.)
- Other circumstances where electronic form is excluded by specific laws or administrative regulations

Questions, answered.
Common questions about eSignature legality in China.
Yes, provided the signature meets the "reliable electronic signature" criteria: exclusive signer control, detectable alteration, and mutual consent. Inkfree's audit trail and authentication features are built to support each of these.
Ordinary electronic signatures (like a typed name) are valid for lower-risk transactions but carry lighter evidentiary weight. Reliable electronic signatures, meeting the ESL's three criteria, are legally equivalent to a handwritten signature or company chop.
Not strictly required by law, but courts more readily treat a signature as "reliable" when it's certified by a pre-approved Electronic Certification Services Provider. Without one, the parties bear the burden of proving reliability themselves.
No. Real estate and other real property transfer documents are specifically excluded from the ESL and require traditional execution.
