[Direct answer]In the Beijing area, the evidence for custody disputes can be categorized into six types. The first type is direct custody factual evidence, including proof of the child's daily residence, pick-up and drop-off records, medical and vaccination records, and attendance and pick-up records at schools and kindergartens. The second type is evidence of stable living conditions, including property ownership or lease certificates for the residence and continuous records of the child attending the same community and school for a long time. The third type is evidence of parenting ability, including income certificates, property status, work schedule, and assistance from family members. The fourth type is evidence of the other party's unsuitability, including records of domestic violence, gambling, alcoholism, and long-term failure to fulfill parental obligations in another location. The fifth type is evidence of the child's wishes, which requires attention to the way of expression and its matching with the child's age and cognitive level. The sixth type is materials showing actual care by grandparents or other relatives. According to Article 1084 of the Civil Code of the People's Republic of China (effective January 1, 2021), the determination of custody rights should prioritize the best interests of the minor child. Paragraph 3 explicitly states that if one of the parents causes harm to the child's physical and mental health, the other parent may request a change in the custody relationship. The party who fails to provide sufficient evidence will bear corresponding adverse consequences.Divorce litigation and family disputesAccording to the program's instructions, the systematicness of the evidence is more important than the weight of a single piece of material.

1. Problem background and typical scenarios

In practice, the most common problem is not a lack of evidence, but rather scattered and disorganized materials. Parties often only keep a few pick-up and drop-off photos or payment receipts, yet are unable to account for the child's continuous care over the past three years; or they may have audio recordings of the other party's phone calls, but the content does not involve the fulfillment of parental obligations. Such evidence is difficult to substantiate claims in court. Another scenario is that grandparents have been providing long-term care, but all relevant records are in the hands of the elderly, requiring assistance in organizing them in advance. There is also a reverse risk: if parties independently film and edit the other party's daily activities for evidentiary purposes, improper methods may lead to questions about the legality of the evidence collection. Therefore, evidence organization should follow standard procedures from the outset: preserving the original carriers, complete context, and time information. For special procedures involving minors' rights and interests, reference can also be made to related provisions.Special services and other casesColumn.

II. Key points of contention

Focus One: How to prove direct custody based on actual circumstances, and whether intermittent single records can reflect continuity. Focus Two: The comparative standard for custody capacity—what level of income disparity is decisive? Focus Three: The allocation of the burden of proof for adverse circumstances of the other party—what level of proof is required for the party seeking a change to establish their case? Focus Four: The determination of grandparental care—what is the legal effect of the grandparents' affidavit? Focus Five: The method of obtaining the minor's wishes—is a separate assessment and fixed procedure necessary? Focus Six: The effect of existing agreements or judgments—how can new evidence override existing arrangements? Focus Seven: Evidence organization in overseas or remote living situations. The above determination standards shall be based on currently effective laws, regulations, and judicial rulings.

III. Professional analysis by Henglue Law Firm

Take a divorce dispute handled by lawyers from our firm as an example. The evidence organization played a decisive role in the determination of custody rights. The plaintiff, Wang *sheng, and the defendant, Zhang *hua, registered their marriage in 2006 and had one daughter (who has already reached adulthood) and one son (11 years old). After marriage, they accumulated assets such as real estate, vehicles, machinery, and insurance. In April 2025, Zhang *hua first sued for divorce, but the lawsuit was dismissed. In August of the same year, the court ruled against the divorce. Two months later, Wang *sheng discovered that Zhang *hua had been having an affair during the marriage and entrusted lawyer Xiong Binrong from our firm to sue again, putting forward six claims, including that the biological child should live with her and that the defendant should pay monthly alimony. Zhang *hua counter-claimed that the plaintiff had transferred assets, fabricated debts, and was unfit to raise the child. The lawyer's approach to presenting evidence was clear and structured: First, organizing the evidence of the dismissal of the divorce lawsuit and the affair to prove that there was no possibility of reconciliation; Second, gathering materials around the children's growth environment, the parties' performance, and their ability to raise the child, arguing that allowing the biological child to live with the plaintiff was more in line with the principle of the best interests of minors. To this end, the lawyer provided continuous proof of the child's academic and living trajectory, daily care, and living conditions; Third, strictly applying the principle of fault liability, demonstrating that Zhang *hua had violated the marital duty of fidelity and was the direct cause of the marriage breakdown; Fourth, verifying each joint debt to prevent the defendant from transferring debts. In the end, the court ruled that the biological child should live with Wang *sheng, and Zhang *hua should pay 550 yuan per month in alimony until the child reaches adulthood. Based on the principles of protecting the rights of the child, the wife, and the innocent party, the court determined that Zhang *hua's marital infidelity constituted a major fault, and the house, car, and truck would belong to Wang *sheng, while the warp knitting machine and warp preparation machine would be divided in a 7:3 ratio, and the education fund and insurance would belong to the children. This case demonstrates that custody evidence cannot be submitted in isolation. It must be corroborated with evidence of fault, property structure, and debt certificates to form a main line from family relationships to capacity and fault, which will significantly enhance the court's credibility.

IV. Practical suggestions and legal basis

Action suggestions: 1. First, list the child's residence, schooling, medical care, and caregiving timeline over the past three years. 2. Retrieve attendance and pick-up records from schools and kindergartens, as well as property and community registration records. 3. Organize income and real estate certificates, paying attention to the time span of bank transaction records. 4. Collect records of the other party's failure to fulfill parental obligations or unfavorable circumstances, including travel and communication records. 5. Gather materials on grandparental care and request them to provide written statements. 6. Secure the child's wishes in an appropriate manner to avoid coercion. 7. Create an evidence inventory and copies, and present the originals in court. 8. Preemptively evaluate and preserve evidence against the other party's potential disposal of assets. Legal basis: - Articles 1084 and 1085 of the Civil Code of the People's Republic of China (effective January 1, 2021); - Interpretation (I) of the Marriage and Family Chapter of the Civil Code of the People's Republic of China by the Supreme People's Court (effective January 1, 2021); - Provisions on evidentiary burden and evidence in the Civil Procedure Law of the People's Republic of China (amended in 2023, effective January 1, 2024).

5. Henglu Law Firm's Reminder

First, the evidence must be continuous. Discontinuous single-point records are difficult to reflect the fact of continuous child-rearing. Second, income proof is not the only standard. The stability of companionship and care is often more crucial. Third, there is a risk that improper evidence collection will be rejected. It is not recommended to secretly film, edit, or obtain the other party's privacy in an improper manner. Fourth, the other party's fault does not necessarily mean losing custody rights. The standard should still be in the best interests of the minor children. Fifth, the certificates issued by the grandparents should specify the care period and content, avoiding general statements. Sixth, attention should be paid to preserving the original carriers of evidence. Chat records should not only be saved as screenshots. Seventh, if the divorce agreement has already stipulated the custody arrangement, changes require proof of the occurrence of statutory circumstances.

VI. Frequently Asked Questions

Q1: What materials are needed to prove that the child has been living with me all along?

Common materials include property ownership or lease certificates, residential registration in the property and community, pick-up and attendance records from schools and kindergartens, medical and vaccination records of the children, daily consumption and utility payment receipts, and written statements from grandparents or neighbors. These materials corroborate each other to form a continuous chain, which is more convincing than a single certificate.

Q2: If the other party's income is much higher than mine, does that mean the custody will definitely be awarded to them?

No. The court makes a comprehensive judgment based on the principle of maximizing the interests of minor children, and income is just one aspect of parenting ability. Factors such as spending time with the child, a stable living environment, emotional connection, and whether the other party has any unfavorable circumstances are equally important. The income gap needs to be supported by authentic and reliable evidence, and the other party's caregiving conditions and willingness should also be evaluated.

Q3: If the child is being taken care of by the elderly, can that count as me raising them?

It can serve as an important support. When grandparents actually undertake the main caregiving responsibilities, family support is a positive factor in child-rearing capacity. The caregiving situation statement, expenditure receipts, and life records provided by grandparents all have reference value. However, it is still necessary to clarify how much actual caregiving has been undertaken by the individuals involved, as well as the stability of the assistance provided by family members.

Q4: If the child says they want to be with the other parent, will the court necessarily comply with their wish?

The court will not accept all the statements made by the children without verification. The court will assess the authenticity of the children's statements and take into account their age, cognitive level, and the environment in which they expressed their views. The court will typically evaluate these factors alongside other circumstances. It is recommended that professional personnel design the questioning methods to avoid making the children feel pressured to take sides, and to prevent emotional expressions from undermining the credibility of the statements.

Q5: The divorce agreement has already stipulated the custody arrangement. Can it still be changed?

You can file a lawsuit to request a change, but you need to provide evidence to prove that there are statutory changes, such as the direct custodian suffering from a serious illness, losing the ability to provide support, abusing or abandoning the child, or causing obvious harm to the child's physical and mental health. Simply having a higher income or a change in job status is usually not enough to overturn the original agreement. The relevant time limits shall be subject to the currently effective regulations. For the procedural connection, you can refer to the relevant provisions.Real estate transactions and construction projectsColumn.
