[Direct answer]In the Beijing area, it is possible, and the investigation and collection of evidence is often a crucial step in the success or failure of divorce litigation. The lawyer's evidence-gathering work includes: guiding the client to systematically organize identity proofs, marriage relationship proofs, property ownership and fault clues; applying to the court to retrieve marriage registration files, bank statements, communication records, etc. according to procedures; in cases involving foreign countries or complex identities, conducting overseas judgment evidence collection, additional certificates, and notarized translations. It should be emphasized that the lawyer's evidence collection must be legal and compliant, and must not infringe on others' privacy or obtain materials by illegal means. The goal is to organize scattered facts into a complete and credible chain of evidence to support the claims of emotional breakdown, property division, and custody rights.

1. Problem background and typical scenarios

Many litigants hold "clues" but cannot provide "evidence": they know that the other party owns property in other cities but lack ownership information; they suspect infidelity but only have vague chat records; they cannot produce foreign court judgments regarding their marital history involving foreign countries. Typical scenarios include: the need to verify the property and financial transactions under the other party's name; the need to prove faults such as domestic violence and infidelity; the need to determine whether foreign divorce judgments are recognized by China; and relatives suing repeatedly during the divorce process on grounds such as family division and property distribution to dilute the litigant's assets. All of these require professional evidence-gathering strategies. For related rules, please refer to the following document:Divorce litigation and legal services for family disputes.

II. Key points of dispute

The controversy over evidence collection focuses on four points. Firstly, the boundaries of evidence collection: lawyers can collect materials held by the parties themselves and apply to the court for evidence collection according to law, but they are not allowed to illegally invade privacy or forge evidence. Secondly, the scope of evidence collection by the court: marriage registration, bank transaction records, communication trajectories, travel records, etc. related to the case, which are collected upon application or ex officio. Thirdly, foreign-related evidence collection: foreign judgments must be accompanied by additional certificates and notarized translations, and a distinction must be made between court judgments on divorce and administrative registration of divorce. Fourthly, the integrity of the evidence chain: the probative force of a single piece of evidence is limited, and it requires timelines, financial trajectories, and written documents to corroborate each other. In the judicial practice of Beijing, the systematic organization of evidence is more decisive for the outcome than a single piece of evidence.

III. Professional analysis by Henglue Law Firm

A foreign-related case of bigamy and marriage invalidation handled by Attorney Bingrong Xiong fully demonstrated the role of lawyers in difficult evidence collection. Li Xiang and Li Li registered their marriage at the Civil Affairs Bureau of Xicheng District, Beijing on May 14, 2018. After marriage, Li Li subjected Li Xiang to domestic violence and psychological abuse, causing him to suffer from moderate depression. Li Xiang entrusted Attorney Bingrong Xiong to sue for divorce, and the lawyer made a breakthrough discovery during the investigation: Li Li had registered her marriage with a Swedish man in 2014, and the Swedish court ruled on divorce in January 2018. However, Li Li failed to apply to the intermediate court for recognition of the divorce judgment according to Chinese law before registering her marriage with Li Xiang, so the previous marriage was not legally dissolved in Chinese law, constituting bigamy. To confirm this key fact, the lawyer conducted systematic overseas evidence collection: applying to the Swedish court for disclosure of the divorce judgment, completing the notarization and Chinese translation of the additional certificate; submitting the provisions of the Swedish Marriage Law to prove that the tax bureau had no authority to dissolve the marriage; and retrieving the marriage registration archives to prove that Li Li submitted the information from the Swedish tax bureau rather than the recognized divorce judgment. The People's Court of Shunyi District, Beijing fully adopted the lawyer's opinion and ruled on April 30, 2026 that the marriage was invalid. This case was handled by Beijing Henglue Law Firm.Xiong BinrongThe attorney (practice license number: 11101202211410897, subject to the document issued by the judicial administrative organ) acts as the agent.

5. Henglu Law Firm's Reminder

The first principle of evidence collection is "legality, timeliness, and traceability". When discovering that the other party has transferred property, committed a fault, or has foreign identity flaws, the earlier you fix the evidence, the more beneficial it will be. Chat records, police reports, bank transaction records, and other original materials must be properly preserved to avoid deletion or modification. At the same time, lawyers have legal boundaries when obtaining evidence. Illegally obtained materials will not only not be admitted, but may also lead to legal risks.

VI. Frequently Asked Questions

Q1: Can a lawyer directly go to the bank to check the other party's transaction records?

It cannot be inquired independently. Lawyers have no right to retrieve others' bank accounts in their private capacity, but they can apply to the court for an investigation order or request the court to retrieve information related to the case, such as bank transactions and property registration, in accordance with the law. The parties themselves should first organize and submit the transaction records and vouchers, and then go through the court's retrieval procedure for the insufficient parts. Evidence collection must be in accordance with the law, and illegally obtained materials will not be admitted as evidence.

Q2: Can a lawyer help me find evidence of the other party's infidelity?

We can assist, but we must operate within the legal framework. Lawyers can guide you in collecting chat records, photos, travel routes, spending records, and other materials to form an indirect chain of evidence. If necessary, we can apply to the court to retrieve relevant materials. For cases involving domestic violence, we can assist in preserving police reports and diagnostic certificates. It is prohibited to use illegal methods such as secretly filming or recording others to infringe on their privacy or hiring people to follow them. Only evidence obtained legally is admissible as proof.

Q3: How do lawyers investigate foreign judgments in cross-border cases?

It is necessary to complete the overseas certificate verification process: apply to the foreign court for the disclosure of the divorce judgment, handle the additional certificate (Apostille) and notarized translation, and distinguish between the divorce judgment issued by the court of that country and the administrative registration divorce; at the same time, it is necessary to verify whether the judgment has been recognized by the intermediate court with jurisdiction in China. Foreign divorce judgments that have not been recognized do not have the effect of dissolving the marriage in China, and the relevant facts must be proven by a lawyer through a complete chain of evidence.

Q4: If I discover that the other party's relatives are filing malicious lawsuits to dilute my assets, can a lawyer gather evidence to counter this?

Yes. During the divorce, if a relative of one party sues on grounds such as family division, loan, etc., the lawyer can represent them as a third party with independent rights of action to participate in the litigation, and require the other party to provide evidence of the entrustment of financial management or the agreement of creditor's rights, the delivery of funds and the clear subject matter; the bank statement only proves the track of funds and cannot be used as the sole basis for creditor's rights. By refuting unfounded and continuous litigation, we can prevent the improper outflow of the couple's joint property.

Q5: Does it cost extra to hire a lawyer to investigate and collect evidence?

The attorney's fees are determined through consultation between the law firm and the client. Investigative evidence collection is typically included in the scope of the agency agreement, while third-party costs such as cross-border evidence collection, notarization translation, and additional certificates are generally paid separately based on actual expenses. It is recommended to clarify the service phases and fee structures before entrusting the case, and to jointly agree on the scope of evidence collection and the associated costs to avoid disputes in the future. Compared to the risk of losing the case due to a lack of evidence, the investment in obtaining evidence in a compliant manner is usually more necessary.
