[Direct answer]In the Beijing area, one can file a claim, but whether it will be supported depends on whether the evidence can convince the court of the fault. According to Article 1087 of the Civil Code of the People's Republic of China (effective from January 1, 2021), when dividing jointly owned property in a divorce, the interests of children, women, and the non-at-fault party should be taken into account. As long as the court can determine that one party is at fault, they may receive a share of the property. This does not require meeting the strict standard of "bigamy or cohabitation with others". If there are only ambiguous chat messages and occasional photos of being together, it is usually difficult for the court to directly determine major fault. However, the court can consider factors such as transferring property, failing to fulfill family obligations for a long time, and being obviously irresponsible towards the family. If the evidence is insufficient, it is necessary to strengthen the collection of evidence as soon as possible or seek breakthroughs in other claims such as custody rights and damages compensation.

1. Problem background and typical scenarios

In reality, parties often discover abnormalities through mobile phone chats, consumption records, hotel spending, and photos taken together, but it's difficult to obtain hard evidence of "cohabitation". There are three typical scenarios: first, there are only ambiguous chat records and frequent transfers, with no direct proof of cohabitation; second, photos are obtained through tracking and filming, but the evidence-gathering method may involve privacy violations; third, there are witness testimonies, but the witnesses have a vested interest in one party. In the judicial practice of Beijing courts, the review of fault evidence is quite strict, requiring not only the authenticity of the content but also the legality of the evidence-gathering method. Insufficient evidence does not mean that one can only give up the claim, but rather requires organizing the evidence chain from a different perspective.

II. Key points of contention

First, what circumstances constitute fault in legal terms, and how to distinguish between "cheating" and "cohabitation". Second, the legal boundaries of evidence of fault—are covertly recorded videos, privately installed surveillance cameras, and unauthorized retrieval of call records admissible? Third, does fault have a fixed impact on property division, or is it subject to discretionary adjustment? Fourth, are the evidence required to prove the breakdown of the marriage relationship the same as that required to prove fault? Fifth, can damages for divorce be claimed simultaneously, and can they be combined with property adjustments? These controversial points directly affect litigation strategies and expectations.

III. Professional analysis by Henglue Lawyers

The practical observations of Henglue Lawyers can be summarized into four points. Firstly, the standard of proof is hierarchical. Bigamy and cohabitation with others constitute statutory major faults and may trigger damage compensation; while general infidelity that does not reach the level of cohabitation is usually considered as a factor for emotional breakdown and discretionary consideration, rather than an inevitable basis for dividing assets in favor of the innocent party. Secondly, the way of obtaining evidence determines the fate of the evidence. Evidence such as self-filming in public places, voluntarily sharing content from the other party's mobile phone, and obtaining consumption and accommodation records through legal channels is generally admissible; however, materials obtained by unauthorized intrusion into others' residences or by hacking accounts may be excluded due to privacy infringement. Thirdly, a chain of evidence is superior to a single piece of evidence. Scattered chat records have limited persuasive force, but if they can be corroborated by transfer time, travel records, or property or utility records of cohabitation, the evidentiary value will be significantly enhanced. Fourthly, multiple approaches should be used simultaneously. Even if there is insufficient evidence of fault, claims such as the other party transferring or hiding assets and failing to fulfill family obligations can be emphasized. At the same time, seeking custody rights and reasonable alimony claims can help achieve substantive benefits. When necessary, applying for a court investigation order or requesting the retrieval of relevant records is a common way to strengthen the evidence.

IV. Practical suggestions and legal basis

Action suggestions: First, fix the existing evidence and fully preserve the time and content of the chat records and transfer certificates to avoid taking things out of context; Second, the evidence-gathering methods must be legal. If you're unsure about the evidence-gathering methods, consult a lawyer first; Third, simultaneously collect clues about the other party's transfer of property, income, and consumption to prepare for the allocation and preservation of property; Fourth, combine the claim of fault with the investigation of custody rights and property clues in the litigation to form an overall plan.

5. Henglue Law Firm's Reminder

First, don't take risks to obtain evidence. Illegally obtained evidence may not be admitted and may even lead to liability for infringement. Second, when there is insufficient evidence of fault, the focus should be on investigating property clues and formulating child custody plans, which often leads to more practical results. Third, the conditions for applying for divorce damages and property compensation are different. Whether they can be used together needs to be determined based on the specific type of fault. Fourth, if you find that the other party has transferred property, you should apply for preservation measures in a timely manner.

VI. Frequently Asked Questions

Q1: Can only chat records prove infidelity?

This is usually not enough. Chat records can corroborate an abnormal relationship, but if the content is vague and lacks corresponding time and identity information, it's difficult for the court to independently determine major faults. It is recommended to combine transfer records, travel and accommodation records, photos, etc. to form a chain of evidence, which will significantly enhance the probative force. If necessary, apply to the court to retrieve relevant materials.

Q2: Will the court accept the evidence obtained through covert filming?

It depends on the way of obtaining the evidence. Materials shot in public places or at home without infringing on others' legitimate rights and interests can generally be admitted; materials obtained by unauthorized entry into others' residences or by hacking into accounts may be excluded due to privacy infringement. It is recommended to consult a lawyer before collecting evidence to avoid the evidence becoming invalid due to illegal methods or even incurring infringement liability.

Q3: How much of the property will the at-fault party be allowed to keep?

There is no fixed ratio in the law, and it is determined by the court at its discretion. Generally, if the infidelity does not reach the level of cohabitation, the tilt is relatively small; if there are major faults such as bigamy, cohabitation with others, or domestic violence, the tilt may be more obvious. The specific ratio depends on the degree of fault, the sufficiency of evidence, the structure of property, and the arrangements for child custody, so it's impossible to give a definite figure in advance.

Q4: Can I still claim damages even if there's insufficient evidence?

This is quite difficult. Divorce damages compensation is based on major faults such as remarriage, cohabitation with others, domestic violence, and abuse and abandonment of family members. Generally, infidelity does not meet this threshold. If the evidence can only prove that the marriage has broken down, it is recommended to focus on property division and child custody rather than claiming damages alone.

Q5: Is it still possible to obtain evidence now?

It's still possible, but you need to act quickly. Evidence may disappear over time, and there are also time limits for preserving consumption and accommodation records. It is recommended to immediately fix the existing materials, sort out the other party's income, accounts, and consumption clues, and, if necessary, entrust a lawyer to apply for an investigation order or preservation measures. The earlier you act, the more complete the available evidence will be, and the greater the initiative in negotiations and litigation will be.

The above answer is based on the judicial practice in Beijing. The judicial interpretations in other provinces and cities may vary. For specific cases, please refer to the local rules and evidence situation.

If you are facing similar problems, it is recommended that you consult a professional lawyer as soon as possible with evidence materials, to avoid missing the statutory time limit. →Divorce litigation legal services·Beijing Henglu Law Firm
