eSignature Legality in China

E-Signature Legality Summary

This guide explains the electronic-signature framework in China, including the governing laws, legal effect, accepted signature methods, validity requirements, exclusions and practical business uses.

Applicable Laws

the Electronic Signature Law of the People's Republic of China and the Civil Code of the People's Republic of China

Legal Status

Electronic records and signatures receive legal recognition in China under the Electronic Signature Law of the People's Republic of China and the Civil Code of the People's Republic of China. The signing process must also satisfy every document-specific rule on identity, evidence, delivery, retention, witnessing, notarization, registration or filing.

Regulatory Authority

Ministry of Industry and Information Technology (MIIT) and the State Cryptography Administration

Legal Recognition (Effect)

Key legal framework:

• Electronic Signature Law of the People's Republic of China (amended 2019)
• Cryptography Law of the People's Republic of China (effective 2020)
• Administrative Measures for Electronic Certification Services (MIIT Order, 2009)
• Provisions of the Supreme People's Court on Several Issues Concerning the Trial of Cases by Internet Courts
• Article 14 of the Electronic Signature Law provides that a reliable electronic signature has the same legal effect as a handwritten signature or seal.

Electronic signatures in China have clear legal recognition, and their legal effect is primarily regulated and established by the 'Electronic Signature Law of the People's Republic of China' (hereinafter referred to as the 'Electronic Signature Law'). This law has been in effect since April 1, 2005.

Article 14 of the 'Electronic Signature Law' explicitly stipulates that a reliable electronic signature has the same legal effect as a handwritten signature or a seal.

Accepted Types of Electronic Signatures

Electronic signature types recognized in China include: Electronic Signature and Reliable Electronic Signature.

• Electronic Signature: Data in electronic form contained in or attached to a data message, used to identify the identity of the signer and indicate the signer's approval of the content therein.

2. According to Article 13 of the 'Electronic Signature Law', an electronic signature that simultaneously meets the following conditions shall be deemed a 'Reliable Electronic Signature':

Exclusivity: When the electronic signature creation data (such as a private key) is used for an electronic signature, it belongs exclusively to the electronic signer.

Sole Control: At the time of signing, the electronic signature creation data is controlled only by the electronic signer.

Alteration Detectability (Signature): Any alteration to the electronic signature after signing can be detected.

Alteration Detectability (Content): Any alteration to the content and form of the data message after signing can be detected.

In practice, an electronic signature that adopts digital signature technology based on public key cryptography and is accompanied by a digital certificate issued by a legally established electronic certification service provider (CA institution) is generally presumed to satisfy the aforementioned reliability requirements.

Legal Requirements for Electronic Signatures

According to the 'Electronic Signature Law of the People's Republic of China' (2019 Revision), the core legality requirements for electronic signatures can be summarized into two levels: "Reliable Electronic Signature" and "Legal Exceptions."

Pursuant to Articles 13 and 14 of the Law, a reliable electronic signature has the same legal effect as a handwritten signature or a seal. For an electronic signature to be legally recognized as "reliable," it must simultaneously satisfy the following four statutory conditions:

Exclusivity of Signature: When the electronic signature creation data (such as private keys or biometric templates) is used for an electronic signature, it belongs exclusively to the electronic signer. This means the signature data should be uniquely bound to a specific signer, and others cannot normally obtain or use it.

Controllability of Signature: At the time of signing, the electronic signature creation data is controlled only by the electronic signer. This requires the signer to have substantial and exclusive control over the signature data during the signing process, such as the private key being securely stored and not leaked or stolen.

Integrity of Content: Any alteration to the electronic signature after signing can be detected. This is typically achieved through technologies such as hash algorithms to ensure that if the signed file content is tampered with, it can be identified during verification.

Integrity of Document: Any alteration to the content and form of the data message (i.e., the electronic document) after signing can be detected. This ensures that not only the signature itself but the entire signed document remains complete and untampered with.

Article 16: Where an electronic signature requires third-party certification, the certification service shall be provided by a legally established electronic certification service provider.

Limitations and Exceptions

According to Article 3 of the 'Electronic Signature Law', the legal effect of documents in the following forms shall not be denied solely because they adopt the form of electronic signatures or data messages; however, the following matters involving personal relations and significant interests and rights are not applicable to electronic signatures:

Documents involving personal relations: Such as contracts or documents related to marriage, adoption, inheritance, etc.

Documents involving the transfer of real estate interests: Such as sales contracts or mortgage contracts for houses or land.

Involving the suspension of public utility services: Such as notices for the suspension of water, heat, gas, or electricity services.

Other circumstances where electronic documents are not applicable as prescribed by laws or administrative regulations: For example, certain litigation documents or specific penalty decisions by administrative organs.

• Supplier procurement contracts and orders.
• Logistics waybills and electronic delivery receipts.
• Distributor/agent cooperation agreements and quality assurance agreements.

Real Estate and Property Services

• Property service agreements, decoration management agreements, and parking space lease contracts.
• Voting documents for property owners' meetings, notice receipts, etc.

• Informed consent forms for subjects in clinical trials.
• Procurement contracts for pharmaceuticals and medical devices, scientific research cooperation, and technical service agreements.

Education Industry

Reason for Use: Service targets (students, parents, faculty, partner enterprises) are geographically dispersed. Enrollment and signing processes need to be simplified to reduce operating costs and achieve efficient archiving and management of agreements.

Common Applications:

• Online course enrollment agreements and tuition installment contracts.
• Faculty employment contracts and internship agreements.
