[Direct answer]In the Beijing area, the custody battle needs to organize four types of evidence around the principle of what is most beneficial to the minor children. Article 1084 of the Civil Code of the People's Republic of China (effective January 1, 2021) stipulates that children under the age of two shall be directly raised by their mothers; where an agreement cannot be reached after the child has reached the age of two, the court shall make a judgment based on the principle of what is most beneficial to the minor children; and where the child has reached the age of eight, his/her true wishes shall be respected. Accordingly, the evidence can be summarized as follows: first, the facts of care; second, the conditions of custody; third, the circumstances in which the other party is not suitable for custody; and fourth, the child's wishes. The evidence should be continuous, verifiable, and mutually corroborating. Scattered materials or certificates prepared after the fact are often difficult to be accepted, so it is better to collect evidence early rather than late.

1. Problem background and typical scenarios

Many litigants only realize at the trial that they don't have decent evidence in their hands. Typical situations include: the child is cared for by one party and the elderly on a daily basis, but there is a lack of written evidence; one party claims to have a high income, but cannot provide records of actual care; one party has clues to the other party's misconduct, but fails to preserve them in a timely manner. When handling similar cases in the Beijing area, lawyers usually advise clients to organize evidence on a monthly basis from the date of separation.Divorce litigation and family disputesIn legal cases, a complete timeline is the foundation for organizing evidence.

III. Professional analysis by Henglue Lawyers

When handling custody cases, Henglue Law Firm emphasizes the chain and timeline of evidence. Taking the divorce dispute handled by attorney Xiong Binrong of our firm as an example: Wang *sheng and Zhang *hua registered their marriage in 2006 and had a son (11 years old). In April 2025, Zhang *hua first sued for divorce, but the court ruled against the divorce. Two months later, Wang *sheng discovered that Zhang *hua had been having an affair during their marriage, so she sued again, claiming to dissolve the marriage, have the child live with her, divide most of the joint property, and seek damages. The attorney organized the evidence around two main lines: first, the breakdown of the marriage and the fault of Zhang *hua, organizing the evidence of the court's ruling against the divorce and the evidence of the affair; second, the custody of the child, combining the child's growth environment, the parties' performance, and their ability to raise the child, arguing that it is more in line with the principle of the best interests of minors for the child to live with the innocent party. The court found that Zhang *hua's infidelity during the marriage constituted a major fault, and ruled in favor of the divorce, with the child being raised by Wang *sheng and Zhang *hua paying 550 yuan per month in alimony. In terms of property division, the court also favored the innocent party.

IV. Practical suggestions and legal basis

Action recommendations: First, establish an evidence inventory and organize care and expenditure receipts in chronological order; Second, preserve the original carriers of chat records, transfer records, and photos to ensure verifiability; Third, if the other party engages in improper behavior, promptly report to the police or seek medical treatment and retain the relevant materials; Fourth, if the children are over eight years old, cooperate with the court's inquiries without interfering with their expression; Fifth, avoid forging or exaggerating materials, as this will seriously undermine credibility once exposed. Legal basis: Articles 1084 and 1085 of the Civil Code of the People's Republic of China (both effective from January 1, 2021), the 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 from January 1, 2021) regarding custody, and the Rules of Evidence in Civil Procedure.

5. Henglu Law Firm's Reminder

Firstly, the key to evidence lies in its consistency and authenticity. Temporarily assembled materials have limited persuasive power. Secondly, electronic evidence should retain its original carrier. Providing only screenshots is easily questioned. Thirdly, accusations against the other party must be supported by evidence. Unsubstantiated claims are hard to gain support. Fourthly, the children's wishes need to be truly reflected. Inducing them will only reduce the score. Fifthly, it's better to collect evidence as early as possible to avoid the loss of key clues.

The rules on statute of limitations and evidence shall be subject to the currently effective laws, regulations, and judicial rulings.

VI. Frequently Asked Questions

Q1: How can I prove that the child has been living with me all along?

It is possible to combine multiple types of materials: photos of pick-up and accompaniment, payment records from schools and training institutions, medical and vaccination records, proof of residence and school attendance, and testimonies from relatives, friends, and neighbors. The key is for the materials to be consistent in time and corroborate each other. According to Article 1084 of the Civil Code of the People's Republic of China (effective January 1, 2021), the continuity of care is an important basis for determining the ownership of custody rights.

Q2: Can chat records and recordings be used as evidence?

Yes, but attention should be paid to authenticity and legality. The original carriers, such as mobile phones or storage devices, should be preserved to avoid submitting only screenshots or edited clips. The method of obtaining the recording must not infringe upon others' legitimate rights or violate prohibitive legal provisions. If the original carriers cannot be opened, other evidence can be used to corroborate it, such as call records and witness testimonies.

Q3: What evidence is needed to prove that the other party is unfit to raise the child?

Common examples include: police reports and injury materials related to domestic violence, records of penalties for gambling or drug abuse, evidence of long-term uncontacted communication, proof of refusal to pay child support, and certificates from schools and communities showing negligent care. The evidence should focus on specific behaviors and their impact on the children, rather than making general judgments about the other party's character.

Q4: If the child is willing to stay with me, do I still need other evidence?

It is still necessary. The true wishes of children who have reached the age of eight are an important reference, but the court will make a comprehensive judgment based on the continuity of life, the parent-child relationship, and the conditions of both parties, and usually arrange for a separate interview. Therefore, in addition to the child's wishes, you should also prepare evidence of the care facts and upbringing conditions, forming a complete chain to avoid relying solely on the child's statement.

Q5: Should evidence be collected before marriage or prepared during the marriage?

It's advisable to start systematically preserving evidence as early as possible, preferably from the moment of separation. During the marriage, attention should be paid to keeping records of payments related to children, medical treatment and accompanying them, which can be used immediately in the event of a dispute. Materials prepared after the fact are prone to being questioned about their authenticity, so the habit of daily preservation is more effective than making a last-minute effort. It's also more convenient for lawyers to evaluate and plan solutions as early as possible.
