[Direct answer]In the Beijing area, if a spouse cheats but there is insufficient evidence, there's no need to obsess over "catching them in the act". Instead, focus on obtaining legal evidence and adopting alternative strategies. According to Article 109 of the Civil Code of the People's Republic of China (effective from January 1, 2021), if the innocent party requests divorce damages, it is limited to five specific circumstances: bigamy, cohabitation with others, domestic violence, abuse or abandonment of family members, and other major faults. Simple infidelity must reach the level of "cohabitation with others" or "other major faults". Article 1087 stipulates that property division shall be determined in accordance with the principles of protecting the rights and interests of children, the wife, and the innocent party. Evidence collection boundaries: Evidence obtained by seriously infringing on others' legitimate rights and interests, violating prohibitive legal provisions, or seriously violating public order and good customs shall not be used as the basis for determining the facts (Article 106 of the Supreme People's Court's Several Provisions on Evidence in Civil Proceedings). Chat records and transfer records can be fixed by oneself, while hotel accommodation records generally need to be retrieved by the court. When evidence is insufficient, it's more practical to sort out the joint property, strive for preferential division, and solidify the results with a mediation plan.

1. Problem background and typical scenarios

Discovering ambiguous chat records, abnormal hotel check-in records, and large-sum transfers, wanting to divorce but unable to provide solid evidence; worrying that the evidence obtained through covert surveillance and recording may be invalid, which might instead lead to infringement lawsuits; struggling with whether to confront the other party directly, but fearing that the evidence might be deleted after the confrontation. Such situations are extremely common in divorce consultations. It is necessary to distinguish two levels of issues: which facts can prove that "the other party is at fault", and which evidence obtained by such means will be recognized by the court. It is more beneficial to focus on obtaining evidence legally and sorting out property matters than to act impulsively to catch the other party in the act. For related ideas, please refer to the following content:Divorce litigation and legal services for family disputes.

II. Key points of contention

There are five key points of contention. Firstly, the distinction between "extramarital affairs" and "cohabitation with others": Cohabitation requires continuous and stable living together, while occasional extramarital affairs generally do not constitute grounds for damages. Secondly, the legality of evidence: Whether secretly filming or recording, tracking, or private detective surveillance are excluded depends on whether the methods seriously infringe upon others' legitimate rights and violate legal prohibitions. Thirdly, the form of evidence and the path of obtaining it: Chat records and transfer records are electronic data and can be preserved by oneself; hotel accommodation records and travel records usually require applying for a court investigation order or obtaining them in accordance with the law. Fourthly, alternative claims when evidence is insufficient: Taking into account property division, compensation for housework, and implementing interests through mediation. Fifthly, the burden of proof: The party without fault bears the burden of proof for the circumstances of the fault, and if the authenticity is uncertain, they must bear the adverse consequences. In the judicial practice of Beijing courts, the determination of "cohabitation" tends to be stricter, and the design of claims is more crucial than the quantity of evidence.

III. Professional analysis by Henglue Lawyers

A foreign-related divorce case handled by Henglue Law Firm provides valuable insights into what to do when evidence is insufficient. Ms. Zhang and Mr. Liu registered their marriage in 1991. Both are now foreign nationals who have lived in Beijing for a long time. They have a daughter who has already reached adulthood, but their marriage fell apart due to Mr. Liu's infidelity. The couple agreed on the ownership of their assets: Ms. Zhang retains ownership of a house in Beijing, a property abroad, savings, financial products, and insurance, while Mr. Liu retains ownership of a house in Shanghai. Since both are foreign nationals, Chinese marriage registration authorities cannot handle their divorce registration. Ms. Zhang therefore entrusted Attorney Xiong Binrong to dissolve their marriage through court litigation and confirm the division of their assets. The attorney confirmed that Chinese courts have jurisdiction, assisted in preparing all the materials for filing the case, comprehensively sorted out the property, savings, financial products, and pension memberships owned by both parties, and proposed a division plan where each party would own their own assets and bear their own debts. The case highlights two points: First, while the facts of the infidelity are important, transforming "the other party's infidelity" into reasonable concessions and bargaining chips in the property division is often more effective than obsessing over chat records in court—the division plan can only be implemented with a clear property inventory and mutually acceptable arrangements. Second, evidence collection must adhere to legal boundaries. Secretly filming or recording, or stalking and harassing others may not only be excluded by the court but also turn oneself from a victim into a defendant in infringement cases. When evidence is insufficient, it is more prudent to clarify the joint assets and carefully draft legal claims.

Evidence obtained in an unlawful manner may be excluded, and it may also lead to infringement lawsuits or even public security penalties.

VI. Frequently Asked Questions

Q1: If the other party cheated but there's not enough evidence, can I get a larger share of the property or compensation during the divorce?

There's no guarantee, as it depends on whether the evidence can prove the statutory fault circumstances. Divorce damages are limited to bigamy, cohabitation with others, domestic violence, abuse and abandonment of family members, or other major faults (Article 1091 of the Civil Code). If the extramarital affair does not reach the level of "cohabitation with others", the claim for compensation may not be supported. Property division is decided in accordance with Article 1087, taking into account the interests of children, women, and the innocent party. The innocent party can usually seek certain concessions, but the proportion will be determined by the court. When the evidence is insufficient, it's more practical to focus on sorting out the joint property and designing a mediation plan than to obsess over the amount of compensation. The conclusions of individual cases shall be based on the evidence and the court's determination.

Q2: Which pieces of evidence of infidelity are legal and valid, and which ones will be excluded by the court?

There are three legal channels: First, self-preserved chat records, transfer records, and consumption receipts. It is important to preserve the original carriers and present them in full screen; Second, repentance letters and guarantees written by spouses, or recorded conversations in legal settings; Third, applying to the court for an investigation order or legally obtaining hotel accommodation records and travel records. High-risk behaviors include: secretly filming or recording in others' rooms, illegally tracking and locating others, hacking into others' social accounts and emails, and using illegal devices for eavesdropping. According to Article 106 of the "Several Provisions of the Supreme People's Court on Evidence in Civil Proceedings", evidence obtained by seriously infringing others' legitimate rights and interests, violating legal prohibitions, or seriously violating public order and good customs shall not be used as the basis for determining the facts, and may also trigger infringement lawsuits.

Q3: How much does it cost to investigate evidence of infidelity and file for divorce?

The attorney's fees are determined through negotiation between the law firm and the client. Common charging methods include charging based on the value of the case or charging by the hour. There is no unified government pricing for these fees. In divorce cases, it is strictly prohibited to engage in illegal contingency fee arrangements. Court fees are charged in accordance with the "Measures for the Payment of Litigation Fees" (State Council Decree No. 481, implemented on April 1, 2007). The fees are accumulated and paid in stages based on the amount of the claim, with the losing party bearing the fees, and the winning party sharing the fees proportionally. For applications for court investigation and evidence collection, property declaration, audits, and appraisals, fees are paid in accordance with the relevant regulations. "Grey investigation companies" often charge tens of thousands of yuan and the evidence obtained may not be legally valid, which may also involve compliance risks. It is recommended to prioritize legal evidence collection channels and spend money on property sorting and litigation planning instead.

Q4: How long does it usually take from evidence collection to sentencing?

It usually takes several days to independently secure evidence. The first-instance litigation in ordinary procedures is concluded within six months and in summary procedures within three months; if it involves applying to the court for investigation and evidence collection, asset evaluation, or audit, the corresponding period will not be included in the time limit for trial, and it will usually take an additional one to three months; if the defendant's whereabouts are unknown and need to be served by public notice, the service alone may take several months. Overall, divorce cases with clear evidence can be concluded within half a year, while those with major property disputes and multiple rounds of evidence collection may take longer than a year. It is recommended to initiate litigation as soon as possible within the three-year statute of limitations and, if necessary, apply for property preservation.

Q5: If you discover that your spouse is cheating on you, what should you do first?

There are four steps to proceed: First, stay calm and save the original carriers of chat records, transfer records, photos, and videos first. Record the entire screen without editing to avoid tipping off the other party; Second, sort out the clues of common property, including real estate, bank accounts, equity, financial management, insurance, and provident funds, so as to have a clear understanding of the situation; Third, if you don't want to expose your cards yet, consult a lawyer first to formulate evidence collection and negotiation plans, and clarify which evidence is legal and which channels can be used to apply for court retrieval; Fourth, if you decide to divorce, file a lawsuit within the three-year statute of limitations and include property division, claims for damages, and evidence investigation requests in the litigation requests. If necessary, apply for property preservation.
