[Direct answer]In the Beijing area, extramarital affairs alone do not automatically lead to a "reduced share" of marital property. However, according to Article 1087 of the Civil Code of the People's Republic of China (effective January 1, 2021), when dividing jointly owned property, the court shall adjudicate in accordance with the principles of protecting the rights and interests of children, the wife, and the innocent party. The court may favor the innocent party. If the at-fault party engages in acts of hiding, transferring, selling, damaging, or squandering jointly owned property, or forging joint debts as described in Article 1092, the innocent party may receive a reduced or no share of the property. If the at-fault party commits major faults such as bigamy, cohabitation with others, or domestic violence as described in Article 1091, the innocent party may also claim damages for divorce. The law does not set a fixed percentage, and the extent of the favorable treatment depends on the evidence. It is recommended to fix the evidence of the at-fault party as soon as possible and claim it together with the divorce litigation.

I. Problem Background and Typical Scenarios

There are various forms of marital faults: infidelity and extramarital affairs, domestic violence, gambling and drug addiction, concealment and transfer of income, and lack of responsibility towards the family. Parties often ask, "Should the other party leave the house with nothing if they cheat?" In fact, there is no legal system of "leaving the house with nothing". The division of assets is still based on the joint property, and the degree of inclination is determined by the court. Typical scenarios include: one party being caught in an extramarital affair; one party gambling and using joint property to repay gambling debts; one party having a record of domestic violence with police reports and injury records; one party transferring large amounts of income to a third party outside the marriage. Different faults correspond to different legal consequences: some affect the proportion of assets, some trigger damages compensation, and some also affect the evaluation of custody rights. In cases involving domestic violence damages, it can also be combined with other circumstances.Personal injury and medical dispute servicesEvaluate the compensation claims.

II. Key points of contention

There are three focal points of the dispute. Firstly, the relationship between "less division" and "compensation": Article 1087 of the Civil Code stipulates that the preferential division and the damage compensation in Article 1091 are not mutually exclusive. However, in the judicial practice of Beijing courts, some cases hold that if the property division has already fully reflected the consideration of fault, there is no need to additionally support the compensation. Secondly, the extent of preferential division: the law does not stipulate a specific proportion. Courts usually adjust it based on equal division and the weight of evidence of fault directly determines the extent of preferential division. Thirdly, the standard of fault determination: the probative force of chat records, accommodation records, guarantee letters, and police reports varies. It is difficult to determine the fault based on a single piece of evidence, and it is necessary to form a chain of evidence. Evidence obtained through illegal means may also be excluded. If there is a dispute over the authenticity of a party's debt, it can be combined with other evidence to determine the truth.Creditor-debtor relations and enforcement case servicesAnalyze and clarify each detail one by one.

III. Professional analysis by Henglue Lawyers

Based on Henglu Law Firm's practical experience in handling divorce cases, the claim of fault must be "accurately defined, supported by solid evidence, and comprehensive in scope". In terms of definition, it is necessary to distinguish between general fault (such as marital discord or occasional disputes) and major fault (including bigamy, cohabitation with others, domestic violence, child abuse, and other serious offenses). Only the latter may trigger compensation for damages. Regarding property distribution, the principle of protecting the innocent party applies, with the compensation typically limited in scope but still valid. For evidence collection, it is crucial to preserve chat records on WeChat, transfer records, affidavits, police reports, and medical records in their original format. Important electronic data should be notarized as soon as possible. Evidence obtained through illegal methods, such as trespassing or tracking, may be deemed inadmissible and could even work against one's own case. In terms of claims, it is recommended to file a lawsuit simultaneously for marital dissolution, child custody, property division, and compensation for damages to avoid additional litigation costs. Experience shows that cases with clear claims and well-documented evidence typically receive more favorable treatment from the court towards the innocent party.

IV. Practical suggestions and legal basis

Legal basis: Article 1043 (Husband and wife shall be faithful to each other) of the Civil Code of the People's Republic of China (effective January 1, 2021), Article 1087 (Principles of property division in divorce, including consideration for the innocent party), Article 1091 (Circumstances of divorce damage compensation), Article 1092 (Division of property shall be less or not divided in cases of concealment and transfer of property, etc.); Interpretation (I) of the Supreme People's Court on the Application of the Marriage and Family Chapter of the Civil Code of the People's Republic of China (effective January 1, 2021) regarding the application circumstances and initiation time of damage compensation. Practical suggestions: Fix the evidence of fault and notarize key electronic data as soon as possible; list and sort out the joint property and debts; claim preferential division and damage compensation simultaneously when suing; and review the authenticity of each debt claimed by the other party. For complex properties such as equity and partnership shares, reference can be made to the relevant provisions.Business and contract dispute services for enterprisesEvaluate the valuation and division path.

5. Henglue Law Firm's Reminder

Three reminders: First, don't take "leaving the house with nothing" as a goal. Courts rarely support completely depriving one party of their property. A reasonable expectation is for a moderate tilt. Both negotiation and litigation should focus on achievable claims. Second, the court may evaluate damages and the division of property together. Submit all claims and evidence at the same time when suing to avoid having to deal with them separately in subsequent cases. Third, pay attention to the timeliness and legality of evidence. Once chat records are deleted, it's difficult to recover them. Document important content with a notarization as soon as possible. If the property is transferred, apply for preservation measures simultaneously. If it involves post-judgment investigation and enforcement, you can combine them with other legal procedures.Creditor-debtor relations and enforcement case servicesAdvance, or throughSpecial services and other case servicesMatch the housekeeping team.

VI. Frequently Asked Questions

Q1: If the other party cheated on me, can I ask him to divide less of the property in the divorce?

There is some basis for this, but it needs to be supported by evidence. According to Article 1087 of the Civil Code, when dividing jointly owned property in a divorce, the court shall make a judgment in accordance with the principles of protecting the rights and interests of children, the wife, and the non-at-fault party. Infidelity, as a violation of the marital duty of fidelity, can be considered one of the factors favoring the non-at-fault party. If the infidelity reaches the level of bigamy or cohabitation with others, the non-at-fault party may claim damages according to Article 1091. However, the extent of the favorable treatment is determined by the court at its discretion, and there is no fixed percentage in the law. Isolated chat screenshots are often insufficient; transfer records, accommodation records, and communication records are needed to form a chain of evidence. It is recommended to first secure evidence before negotiating or suing, to avoid tipping off the other party.

Q2: What evidence do I need to prepare to prove the other party's fault during the marriage?

Common effective evidence includes: chat records on WeChat or text messages admitting an intimate relationship (retaining the original carrier), intimate photos and videos, hotel or travel records, guarantee letters and letters of repentance written by the other party, police reports issued due to domestic violence, police response records, injury appraisals and medical records, witness statements, as well as loan and punishment records resulting from bad habits such as gambling. When collecting evidence, two points should be noted: first, legality—it is prohibited to invade residences, track or eavesdrop illegally; second, completeness—exported electronic data should be notarized or witnessed by a notary office as much as possible. The evidence should be organized around "the existence of the wrongdoing, its duration, and the consequences it caused," which will enhance its probative value.

Q3: How much does it cost to file a divorce lawsuit against the at-fault party?

According to the "Procedures for the Payment of Litigation Costs" (implemented on April 1, 2007), the acceptance fee for each divorce case is between 50 yuan and 300 yuan; for cases involving property division, if the total value of the property does not exceed 200,000 yuan, no additional fee is required. For the portion exceeding 200,000 yuan, a fee of 0.5% shall be paid. Claims for preferential division and damages will increase the calculation of the subject matter, but the fees corresponding to the successful part will be borne by the other party. The attorney's fees shall be determined through consultation based on the complexity of the case and the workload, and the contract of entrustment shall prevail. Marriage-related cases are not allowed to implement risk-based representation according to law. It is recommended to first sort out the property list and evidence, and then confirm the plan and budget with the lawyer to avoid blindly expanding the claims and increasing the costs.

Q4: In divorce litigation, if one party alleges that the other party is more at fault, how long does it usually take to resolve the case?

The first-instance ordinary procedure shall be concluded within six months, and the summary procedure within three months. Cases with concentrated disputes and clear evidence are mostly subject to the summary procedure; those involving property investigation, appraisal, or the other party's disagreement with the divorce may be transferred to the ordinary procedure or even require a second lawsuit. After the first judgment refusing divorce, if there are no new circumstances or new grounds, no further lawsuit may be filed within six months. The fixation and cross-examination of fault evidence will increase the workload, but generally will not significantly prolong the trial period; if the other party raises a jurisdiction objection, applies for appraisal, or countersues, the trial period will be extended accordingly. Overall, expect a trial period of six months to one year. During this period, you can also strive for a faster resolution through court mediation.

Q5: If you find that the other party has made a mistake, what should you do first?

Here's the translation of the Chinese (Simplified) sentence into English, with a detailed explanation: Suggested four steps: First, stay calm and secure evidence. Keep and back up chat records, transfer records, and original photos. If necessary, have them notarized. Never confront the other party directly to avoid tipping them off. Second, sort out the list of joint assets and debts, and check whether there are any unusual dispositions under the other party's name. Third, consult a lawyer to assess the nature of the fault—whether it's a factor of property bias or a major fault entitling you to claim damages—and determine an overall plan for custody rights and property division. Fourth, weigh the pros and cons of negotiated divorce versus litigious divorce. In the agreement, you can include fault compensation clauses. If no agreement is reached, promptly file a lawsuit and apply for property preservation. Throughout the process, ensure legal evidence collection and, if necessary, involve a lawyer in the negotiations.
