[Direct answer]In the Beijing area, if it meets the four statutory requirements, it is considered reliable and has the same legal effect as a handwritten signature or a stamp. According to the Electronic Signature Law, an electronic signature is considered reliable if it meets the following conditions: First, the electronic signature creation data belongs to the electronic signatory exclusively when used for electronic signatures; Second, the electronic signature creation data is only controlled by the electronic signatory when signing; Third, any changes to the electronic signature after signing can be detected; Fourth, any changes to the content and form of the data message after signing can be detected. The parties may also choose to use electronic signatures that meet the reliability conditions agreed upon by them. Reliable electronic signatures have the same legal effect as handwritten signatures or stamps. In practice, using digital certificates issued by qualified electronic certification service providers and combining with techniques such as time stamps can usually better meet the above reliability requirements; while "electronic signatures" inserted in the form of images may not meet the reliability conditions. It should be noted that the parties may agree to use electronic signatures and data messages to conclude contracts, except for cases involving marriage, adoption, inheritance, and other legal matters where the use of electronic documents is explicitly prohibited by law.

I. Problem background and typical scenarios

Electronic contracts are becoming increasingly popular, and "whether electronic signatures are reliable" has become a common question. Typical scenarios include: one party to a contract signed online denying that they signed it or claiming that the signature is not authentic; enterprises using electronic signature platforms to enter into contracts, leading to disputes over the validity of the signature. The disputes focus on whether electronic signatures are "reliable", whether they can be tampered with, and how to provide evidence.

II. Key points of dispute

First, the statutory requirements for a reliable electronic signature; Second, the role of digital certificates and time stamps; Third, the effectiveness of the parties' agreed conditions; Fourth, the relationship with the effectiveness of handwritten signatures; Fifth, the application restrictions and evidence collection of electronic documents. In practice, technical reliability and proprietary control are the core issues.

III. Professional analysis by Henglue Law Firm

The first layer is the statutory four elements. A reliable electronic signature requires that the signature data is unique to the signatory, controlled solely by the signatory at the time of signing, and any alteration to the signature or the content of the electronic document after signing can be detected; these four elements together guarantee the uniqueness, control, and non-tamperability of the signature. The second layer is the technical implementation method. Using digital certificates issued by qualified electronic certification service providers, combined with technologies such as time stamps and blockchain, is typically easier to meet the reliability requirements. The platform should be able to provide a complete record of the signing process, signature verification services, and evidence preservation certificates. The third layer is the effectiveness agreed upon by the parties. The law allows parties to independently stipulate the conditions that a reliable electronic signature should meet; as long as the agreement does not violate mandatory legal provisions, an electronic signature that meets the agreed requirements can be deemed reliable. The fourth layer is the effectiveness and exceptions. A reliable electronic signature has the same legal effect as a handwritten signature or a stamped signature; however, in cases involving marital, adoption, inheritance, or other legal relationships where electronic documents are not applicable, electronic signature methods cannot be used exclusively. The fifth layer is the burden of proof. In the event of a dispute, the party claiming the validity of the electronic signature typically needs to provide records of the signing process, digital certificate information, signature verification reports, platform evidence preservation, and technical explanations to prove that the signature is unique, controlled, and unaltered; if the other party denies this, verification can be conducted through appraisal or platform verification. Henglue Law Firm Tip: Enterprises should choose compliant electronic signature platforms, clearly stipulate the use of electronic signatures and verification methods in contracts, and properly preserve signing records and certificate materials.

IV. Practical suggestions and legal basis

The first step is to select an electronic signature platform with qualified credentials and reliable technology; the second step is to stipulate in the contract the use of electronic signatures, signature verification, and storage of evidence; the third step is to ensure that the signature is controlled by the signatory and the identity is authentic at the time of signing; the fourth step is to store digital certificates, signing records, signature verification reports, and storage documents; the fifth step is to verify through the platform or apply for appraisal in the event of a dispute. The main legal basis: Articles 13 and 14 of the Electronic Signature Law of the People's Republic of China and related provisions; the provisions on contract form in the Contract Chapter of the Civil Code of the People's Republic of China. The specific application shall be subject to the currently effective regulations.

VI. Frequently Asked Questions

Q1: Are electronic signatures as legally binding as handwritten signatures?

A reliable electronic signature has the same legal effect as a handwritten signature or a stamped signature. Whether it is "reliable" depends on whether it meets the conditions of exclusive ownership of the signature data, control by the signatory at the time of signing, and the ability to detect changes to the signature and content after signing. An electronic signature in the form of an ordinary image may not meet the requirements of reliability, and its validity may be questioned.

Q2: What are the requirements for a reliable electronic signature?

There are four conditions: the signature generation data belongs to the signatory when it is used for signing; the data is only controlled by the signatory when signing; any changes to the signature after signing can be detected; and any changes to the content and form of the electronic document after signing can be detected. The parties may also agree on electronic signatures that meet the reliable conditions stipulated in their agreement.

Q3: Is an electronic stamp covered by a picture valid?

There are uncertainties regarding the validity of electronic signatures. Electronic signatures inserted solely in the form of images typically cannot prove that the signature data is proprietary, controlled, and unalterable, making it difficult to meet the requirements for reliable electronic signatures and prone to being denied in the event of a dispute. It is recommended to use digital certificates issued by qualified platforms for signing to enhance reliability and evidentiary value.

Q4: In which situations can't electronic signatures be used?

When it comes to marital, adoption, inheritance, and other identity-related matters, as well as situations where electronic documents are not applicable according to legal provisions, they cannot be handled solely through electronic signatures or data messages. Additionally, if the parties agree not to use electronic forms, they shall abide by their agreement. Before using electronic forms, it is necessary to confirm whether the transaction matters fall within the scope of exclusion from application.

Q5: If the other party denies the electronic signature, how can I provide evidence?

Evidence can be recorded and provided through the platform with technical materials. Provide records of the signing process, digital certificate information, signature verification reports, time stamps, and platform-stored evidence materials to prove that the signature is unique, controlled, and unaltered. If necessary, apply for professional appraisal or request the platform to issue a verification certificate. Choosing a compliant platform and fully preserving the materials are key to successful evidence collection.
