[Direct answer]In the Beijing area, a spouse's infidelity does not have the effect of a "one-vote decision" on the custody of children. According to Article 1084 Paragraph 3 of the Civil Code of the People's Republic of China (effective January 1, 2021), the custody of children who have reached the age of two shall be decided by the people's court in accordance with the principle that is most beneficial to the minor children. When the children have reached the age of eight, their true wishes shall be respected. Infidelity may only affect the custody arrangements if it reflects specific circumstances that are detrimental to the physical and mental health of the children; at the same time, evidence of infidelity can be used as a factor to favor the innocent party in the division of property. It is recommended that while fixing evidence of fault, systematically organize evidence of the advantages of the children living with the parent who has custody.

I. Problem background and typical scenarios

After discovering that their spouse has been having an affair, the most common question people ask is "If he cheated, does that mean the child will definitely belong to me?" Typical scenarios include: believing that obtaining evidence of the affair will help them regain custody rights; being counterattacked with "you're also at fault"; both parties providing evidence of their income and housing conditions; and parents still disagreeing even after the child, who has reached the age of eight, has expressed their wishes clearly. In practice, the focus of custody disputes is on ensuring the child's stable living and growth environment, rather than simply making moral judgments.

II. Key points of contention

The controversy focuses on four points. Firstly, the distinction between fault and custody eligibility: infidelity mainly affects the division of property and compensation for damages, while custody rights still depend on the conditions of custody. Secondly, stability of life: if the children have lived with one party for a long time and their education and medical care are stable, changing their environment is generally considered unfavorable. Thirdly, the children's wishes: those who have reached the age of eight should be respected for their true wishes. Fourthly, evidence confrontation: both parties' accusations against each other for failing to fulfill their custody obligations need to be supported by evidence. For matters involving the division of property, it can be combined with other evidence.Legal services for family disputesCoordinate and advocate for the overall interests of the company and employees.

III. Professional analysis by Henglue Law Firm

The core of a custody case is to build evidence around the interests of the children. In a divorce case handled by Attorney He Ningning, Xiao Ya and Xiao Lei registered their marriage in November 2013. Their eldest son was born in September 2015 and their eldest daughter in October 2018. The two children have been living with their mother for a long time. The father, who was often away for business, had been living apart from his wife for more than ten years, and the custody obligation was mainly borne by the mother. The father first sued for "one child being raised by each parent", but the mother entrusted Attorney He Ningning to insist that both children be raised by herself. The lawyer collected travel records, residence certificates, WeChat chat records, and children's education and medical records to prove that the father had been absent from family life for a long time. At the same time, based on the principle of "the best interests of minors", the lawyer demonstrated the stability of the children living with the mother and the insufficiency of the father's conditions for long-distance care, and claimed that the debts incurred by the father using the mother's ID card to apply for credit cards should be borne by the father. The court adopted the core defense opinion, broke through the common "balanced" judgment, mediated the divorce and granted the mother custody of both children, and the father was legally obliged to pay alimony. The division of property and debt assumption were also favorable to the mother. This case was handled by Beijing Henglu Law Firm.He NingningThe attorney (practice license number: 11101202511925103, subject to the certificate issued by the judicial administrative organ) acts as the agent. In another case of divorce due to infidelity during marriage, the court determined that the at-fault party's infidelity during marriage constituted a major fault, and the marital relationship had indeed broken down. The court ruled that the child born during the marriage would live with the non-at-fault party, and the at-fault party would pay 550 yuan per month in child support until the child reaches adulthood. Additionally, the court supported the non-at-fault party in obtaining 70% of the jointly owned property in accordance with the principle of protecting the non-at-fault party's interests. This shows that infidelity has an indirect impact on custody rights, and the final decision still depends on the best interests of the child.

IV. Practical suggestions and legal basis

The legal basis is Article 1084 Paragraph 3 (principles for determining custody rights), Article 1087 (dividing joint property in accordance with the principles of taking care of children, protecting the rights and interests of the wife and the non-at-fault party), and Article 1091 (the non-at-fault party has the right to request damages if the divorce is caused by major faults such as bigamy or cohabitation with others) of the Civil Code of the People's Republic of China (effective from January 1, 2021). Practical advice: Fix evidence of infidelity for property and compensation claims; systematically organize children's living, education, and medical records; avoid violent conflicts and acts of seizing and hiding children; for children over the age of eight, let them express their true wishes in a suitable environment.

5. Henglu Law Firm's Reminder

Don't equate "the other party cheating" directly with "automatic custody rights". Custody rights focus on the interests of the children, while the impact of cheating is more reflected in the bias in property division and damages compensation. Three tips: First, the evidence of fault must be obtained legally, and attention should be paid to the methods and occasions of secret filming and recording; Second, evidence of custody advantages is more important than accusing the other party; Third, if the other party steals or hides the children, you should promptly sue to clarify the custody relationship and prevent the children's living conditions from being suspended for a long time.

VI. Frequently Asked Questions

Q1: If the other party cheats, will I definitely get custody of the child?

Not necessarily. The court makes a decision based on the principle of what is in the best interests of the minor children, and respects the children's wishes if they are over eight years old. Infidelity itself does not directly determine the custody of the children. It only constitutes a factor of influence when it is accompanied by specific circumstances that are detrimental to the children's growth (such as living with a third party for a long time and neglecting to care for them). The key to winning custody is the stability of the children's lives and the parents' own conditions for raising them, rather than moral superiority. We should not take the outcome for granted.

Q2: What evidence do I need to prepare to fight for custody rights?

Including: records of the children living with the parent (proof of school attendance, medical bills, daily living vouchers), the parent's stable income and proof of residence, evidence that the other parent failed to fulfill their duty of support (long-term separation, absence from family life records), and the true wishes expressed by children aged eight or above. The evidence should focus on the "interests of the children" rather than simply accusing the other party. The more systematic the materials are, the more they can support the argument for the stability of the custody arrangement.

Q3: What are the approximate legal fees and litigation costs for a custody dispute?

The attorney's fees shall be negotiated by both parties in accordance with the law, and risk-based attorney fees shall not be implemented in marital and family cases. The litigation fees shall be accumulated in accordance with Article 13 of the "Measures for the Payment of Litigation Fees". In cases of pure custody disputes involving small amounts of property, the litigation fees are relatively low. Before entrusting the attorney, the client should request a written fee breakdown and a phase-by-phase agreement, clearly stating whether the fees will be charged in stages for the first instance, the second instance, and the enforcement phase, in order to avoid subsequent disputes over fees.

Q4: How long does a custody litigation usually take?

The first-instance ordinary procedure shall be concluded within six months, and the simplified procedure within three months; if there is no major dispute between the parties or they reach an agreement through mediation, the time period will be significantly shorter. If there are difficulties in providing evidence or the need to investigate the other party's residence and income situation, the time will be extended accordingly. It is recommended to initiate the procedure as soon as possible to avoid the children's living conditions being in a state of uncertainty for a long time and to reduce the impact on the children.

Q5: If you discover that your partner is cheating on you, what should you do specifically?

Four steps to proceed: 1. Legally secure evidence of the other party's wrongdoing, such as chat records and photos, and pay attention to the method of evidence collection. 2. Clearly define the scope of claims (custody rights, alimony, property division, and damages). 3. Organize evidence demonstrating the advantages of the child living with you. 4. Entrust a lawyer to develop litigation or mediation strategies. Throughout the process, avoid emotional conflicts and prevent overly aggressive actions that may harm the child's interests.
