Beijing IP Court Clarifies Standards for Notarized Online Evidence

Brand owners pursuing IP enforcement in China have long understood that notarized evidence is the gold standard. A properly notarized screenshot of a counterfeit listing, a notarized test buy record, or a notarized capture of infringing online content carries a statutory presumption of authenticity that unauthenticated evidence simply cannot match. But a series of recent Beijing IP Court rulings has delivered an important clarification: not all notarized evidence is created equal. The court has increasingly scrutinized the quality and completeness of notarial certificates, rejecting or giving reduced weight to notarized evidence that fails to document the full evidence collection process with sufficient detail. These rulings establish evolving notarized online evidence standards that brand owners and their counsel must understand to ensure their enforcement evidence withstands judicial scrutiny. The core message from the court is clear: the notarial certificate must establish an unbroken chain of custody from device preparation through evidence capture to certificate issuance, with every step documented in sufficient detail that a reviewing judge can independently verify the integrity of the process. This guide analyzes the key rulings, identifies the specific notarial certificate deficiencies the court has flagged, and provides practical guidance on what brand owners must include in their notarization requests to produce court-ready evidence.

1. The Beijing IP Court's Evolving Scrutiny of Notarized Evidence

The Beijing IP Court has issued several rulings in 2025 and 2026 that collectively establish higher expectations for notarized online evidence. These rulings do not change the statutory presumption of authenticity that notarized documents enjoy under China's Notarization Law. Rather, they clarify what constitutes sufficient notarization to trigger that presumption in the online evidence context, and they identify specific deficiencies that can cause notarized evidence to be excluded or given reduced weight.

In a significant 2025 trademark infringement case, the court excluded notarized screenshots of infringing product listings because the notarial certificate failed to describe the device preparation process. The certificate stated that the notary observed the evidence collection but did not document that the device had been cleared of browsing history, cookies, and cached data before the evidence was accessed. The court held that without device preparation documentation, the possibility that the captured content reflected cached or pre-loaded material rather than live platform content could not be eliminated, and the evidence was therefore unreliable.

In a 2026 unfair competition case involving online price erosion, the court gave reduced weight to notarized evidence of unauthorized seller storefronts because the certificate did not document the complete navigation path. The certificate described the final listing pages but did not record how the notary navigated from the platform homepage to those pages. The court noted that without navigation path documentation, it could not verify that the listings were publicly accessible through normal platform navigation rather than accessed through direct URLs or manipulated links.

In a third case involving live-stream infringement on Douyin, the court rejected notarized evidence of a broadcast capture because the certificate did not establish temporal continuity. The certificate described the broadcast content but contained gaps in the timestamp documentation, making it impossible to determine whether the captured content represented a continuous recording or edited segments. The court held that temporal gaps in the notarial record undermined the reliability of the evidence as an accurate representation of the complete broadcast.

2. The Chain of Custody Imperative

The common thread connecting the Beijing IP Court's recent rulings is the requirement for a documented chain of custody that establishes the integrity of the evidence from the moment of collection through presentation in court. The chain of custody concept, familiar in physical evidence contexts, has been extended by the court to online evidence, where the risks to evidence integrity are different but equally significant.

The chain of custody for online evidence begins before any content is accessed. The notarial certificate must document the initial state of the device used for evidence collection—that browsing history, cookies, cached files, and temporary internet files were cleared, that no pre-loaded content existed, and that the device was connected to the internet through a standard network configuration. This documentation eliminates the possibility that the captured content was pre-existing on the device rather than accessed from the live platform.

The chain continues through the evidence collection process itself. The certificate must document the complete navigation path from a neutral starting point—typically the platform's public homepage or a general search engine—to the target content. Every step, every click, every URL transition must be recorded. The certificate must establish that the content was accessed through normal platform navigation available to any user, not through direct URLs, cached links, or other non-standard access methods. This documentation eliminates the possibility that the content was fabricated, altered, or accessed through privileged channels.

The chain must document temporal continuity throughout the collection process. Timestamps must be recorded at each significant step, establishing the duration of the collection session and confirming that the recording is continuous without gaps. If the evidence collection spans multiple sessions—for example, a test buy that involves separate sessions for purchase, shipping tracking, and package unboxing—each session must be separately documented with its own complete chain of custody, and the connections between sessions must be established.

The chain concludes with the certificate issuance and evidence preservation. The certificate must describe how the collected evidence was preserved—stored on what media, with what access controls, and with what integrity verification. The evidence exhibits attached to the certificate must be cross-referenced in the certificate text with unique identifiers, enabling the court to verify that the exhibits presented are the same exhibits referenced in the certificate.

3. Specific Elements a Court-Ready Notarial Certificate Must Include

Based on the Beijing IP Court's recent rulings, a notarial certificate that will withstand judicial scrutiny must include specific, detailed elements. Brand owners should use this checklist when instructing notaries and reviewing draft certificates before they are finalized.

The certificate must begin with a comprehensive description of the notarization environment. This includes identification of the notary public by name, license number, and notary office; identification of the applicant or client requesting the notarization; the date, time, and location of the notarization; and identification of all persons present during the notarization process. For remote notarization under the 2026 regulations, the certificate must additionally document the digital platform used, confirm its Ministry of Justice approval status, and describe the remote connection configuration.

The device preparation section must document the cleaning process with specificity. The certificate should state that browsing history was cleared, cookies and cached files were deleted, temporary internet files were removed, and no relevant content existed on the device before the evidence collection began. The certificate should identify the device type, operating system, and browser used. Screen captures documenting the clean device state—showing empty browsing history and cleared cache—should be attached as exhibits.

The navigation documentation section must record the complete access path. The certificate should describe navigation from a specified starting point—the platform homepage URL, a general search engine, or another neutral access point—through each intermediate step to the target content. Every URL transition, search query, and page load should be documented. The certificate should confirm that all content was accessed through normal, publicly available navigation without use of direct links, privileged access, or non-standard methods.

The content capture section must document what was observed and captured with sufficient detail that a reader can understand the content without viewing the exhibits. The certificate should describe the content of each captured page, identify the specific elements relevant to the enforcement matter, and cross-reference each exhibit. Timestamps should be recorded at the beginning and end of the capture session, and at each significant transition point.

The preservation and exhibit section must establish the connection between the certificate and the attached evidence. Each exhibit should be uniquely numbered and described. The certificate should state the format in which evidence is preserved, the storage media, and any integrity verification measures applied. The certificate should be signed, sealed, and registered in accordance with notarial practice requirements.

4. Practical Guidance for Instructing Notaries

Brand owners and their counsel cannot simply engage a notary and assume the resulting certificate will meet the Beijing IP Court notarization standards. The notary's professional standards and the court's evidentiary expectations may not be perfectly aligned, particularly as the court's standards continue to evolve. Active instruction and quality control by the requesting party are essential.

Before the notarization session, provide the notary with a written instruction document specifying the evidence to be collected, the navigation path to be followed, and the specific elements to be documented. The instruction should reference the Beijing IP Court's recent rulings and explain that comprehensive documentation is required for judicial admissibility. Many notaries appreciate clear guidance on what the requesting party needs, as it aligns their work product with the client's enforcement objectives.

During the notarization session, ensure that the notary documents each step as it occurs. If the notary proposes to summarize rather than detail certain steps, respectfully request detailed documentation. The time to ensure certificate completeness is during the session, not after the certificate is drafted. If screen recording is being used in addition to static screen captures, confirm that the recording is continuous and that timestamps are generated by a reliable time source.

Before the certificate is finalized, review the draft carefully against the checklist of required elements. Identify any gaps or ambiguities and request supplementation. A certificate that is incomplete when issued cannot easily be remedied later; the notary can only certify what they observed, and if the observation was inadequately documented, the deficiency may be permanent. The investment in thorough review before finalization is far smaller than the cost of having evidence excluded in litigation.

For enforcement programs involving repeated notarization—ongoing monitoring and enforcement against persistent counterfeiters—develop a standardized notarization instruction template and build relationships with notaries who understand IP enforcement requirements. Consistent quality across multiple notarizations is achieved through clear expectations and ongoing feedback.

5. Strategic Implications for Brand Enforcement Programs

The Beijing IP Court's clarified notarized online evidence standards have strategic implications that extend beyond individual case preparation. Brand owners should integrate these standards into their overall enforcement program design.

• Build notarization quality into enforcement budgets. A cheaper notarization that produces a deficient certificate is not a cost saving; it is a wasted expenditure if the evidence is excluded. Budget for thorough notarization with experienced notaries who understand IP evidence requirements. The cost difference between minimal and comprehensive notarization is modest relative to the cost of failed enforcement.
• Audit existing notarized evidence for deficiencies. Review notarial certificates in pending or anticipated enforcement matters against the Beijing IP Court's standards. Identify certificates that may be vulnerable to challenge and consider whether supplemental notarization or alternative evidence can address the deficiencies before they become case-dispositive issues.
• Develop notarization protocols for different evidence types. The documentation requirements for an e-commerce listing capture differ from those for a live-stream recording or a test buy transaction. Develop evidence-type-specific protocols that address the unique chain of custody considerations for each evidence category.
• Stay current with evolving judicial standards. The Beijing IP Court's notarized evidence standards continue to develop through new rulings. Monitor significant decisions and update notarization protocols accordingly. What was sufficient last year may be insufficient this year as judicial expectations evolve.

The Beijing IP Court's message is clear: notarized evidence is entitled to a presumption of authenticity, but that presumption rests on the quality and completeness of the notarization process as documented in the certificate. Brand owners who invest in meeting the court's clarified notarial certificate requirements will produce evidence that survives scrutiny and supports successful enforcement. Those who treat notarization as a formality will find their evidence vulnerable to the types of challenges the court has increasingly sustained.

Summary: The Beijing IP Court has clarified through recent rulings that notarized online evidence must be supported by detailed notarial certificates documenting the complete evidence collection process to receive full evidentiary weight. The court has excluded or discounted notarized evidence due to inadequate device preparation documentation that failed to eliminate the possibility of cached or pre-loaded content, incomplete navigation path recording that could not verify public accessibility, and temporal gaps in timestamp documentation that undermined recording continuity. The rulings establish a chain of custody requirement spanning device preparation with clean-state verification, complete navigation path from neutral starting point to target content, continuous temporal documentation with timestamps at all significant steps, and evidence preservation with cross-referenced exhibits. A court-ready notarial certificate must include environment description identifying all participants and the notarization context, device preparation documentation with clean-state screen captures, complete navigation documentation recording every URL transition and search step, detailed content capture description with cross-referenced exhibits, and preservation documentation establishing the connection between certificate and attached evidence. Brand owners should actively instruct notaries with written specifications, provide real-time oversight during notarization sessions, thoroughly review draft certificates before finalization, and develop standardized protocols for recurring enforcement needs. The strategic implications extend to enforcement budgeting that prioritizes notarization quality, auditing existing evidence for potential deficiencies, developing evidence-type-specific protocols, and monitoring evolving judicial standards. The court's clarified online evidence authentication standards reward investment in thorough notarization; brand owners who meet these standards will produce evidence that survives challenge and supports successful enforcement.
