What are the types of evidence of derailment in Ningbo

When getting divorced and trying to prove the other party’s infidelity, many people only have a few screenshots of suggestive chats or a secretly filmed video, and they’re not sure whether that’s enough or admissible as evidence. First of all, the evidence of derailment mainly includes legal evidence such as electronic data, documentary evidence, audio-visual materials, witness testimony and so on (Article 66 of the Civil Procedure Law). The evidence must be true, legal and relevant to the case, and a complete chain of evidence can be formed to effectively prove the fact of derailment. One kind of evidence alone is often not enough, and evidence obtained by illegal means such as invasion of privacy and invasion of other people's residence may be excluded. At the same time, it is important to clarify “what needs to be proven”—whether it is to demonstrate a breakdown of the marital relationship, to claim divorce-related damages, or to recover property that was gifted to a third party. The required strength of evidence varies significantly depending on the specific objective.

1. First, let's look at the law: types of evidence and exclusion of illegally obtained evidence.

Article 66 of the Civil Procedure Law (amended in 2023) stipulates that the evidence includes: statements of the parties; documentary evidence; material evidence; audio-visual materials; electronic data; testimony of witnesses; appraisal opinions; inquest records. In adultery cases, the commonly used types of evidence include electronic data (WeChat chats, bank transfer records), documentary evidence (guarantee letters, commitment letters, receipts), audio-visual materials (photos, videos, recordings), witness testimony (from neighbors, colleagues, relatives, and friends), and statements by the parties involved.

The “legality” of evidence serves as the threshold. Article 106 of the interpretation of the Supreme People's Court on the application of the civil procedure law of the the People's Republic of China of China stipulates that evidence formed or obtained by means of seriously infringing upon the legitimate rights and interests of others, violating the prohibitive provisions of the law or seriously violating public order and good customs shall not be used as the basis for determining the facts of the case. To cite a few typical boundaries: installing a camera in one's own home (the common residence of husband and wife) to capture a spouse taking a person home can generally be accepted; In hotel rooms or other people's houses, equipment is secretly installed to shoot, or the door is broken into to shoot, suspected of invasion of privacy and illegal invasion of the house, the evidence may be excluded, and the photographer may also bear public security or civil tort liability. Tracking candid photos, tapping phone tapping, there is also a risk of exclusion. The first principle of evidence collection is "legal means", and the second principle is "content is strong".

There are several high-frequency questions about the legality of the evidence collection scene, which are explained together: shooting the opposite party and the opposite sex in public areas such as the hotel lobby and corridor is generally legal and available; shooting in public places, your own car and public areas of the community does not involve intruding into private space; on the contrary, entering the hotel room, turning over the window, unlocking and sneaking into other people's houses for shooting belong to intruding into private space, with high probability, it could also trigger policing or criminal liability. Regarding the chat records in the spouse's mobile phone: there are differences in judicial attitudes when looking through the records obtained by the spouse's mobile phone without consent. most courts do not exempt from examination because of "husband and wife relationship", but still judge according to whether the evidence collection seriously infringes privacy-the chat records of both parties saved in their mobile phones, the contents sent by the other party to the shared equipment of the family, and the audio and video recordings admitted by the other party are much safer than "screenshots after peeping. Another practical technique is to fix the "time and place" element: photos and videos should contain verifiable time watermarks and surrounding environment (shop signs, road signs, newspapers of the day) as far as possible to endorse the authenticity of the evidence; At the beginning of the recording, the identities and dates of both parties should be confirmed to avoid unclear "who is talking.

2. six types of evidence are disassembled one by one: what to take and how to take it

1. Electronic data (WeChat/QQ/SMS/Email, etc.): The chat record should keep the original carrier of the mobile phone, instead of just taking screenshots -- during the trial, the judge can ask the court to demonstrate the login and flipping process; the recording screen evidence should show the process of complete unlocking, entering the chat and scrolling browsing; the key contents (admitting derailment, calling intimacy, agreeing to meet) continuous screenshots and attaching time. According to the Yinzhou Court's White Paper on the Trial of Marriage and Family Cases (2019-2021), there are many defects in electronic evidence such as WeChat in Ningbo divorce cases and it is difficult to accept it. It is necessary to retain the original carrier and notarize it as far as possible.
2. Transfer and consumption records: transfer to the third party, red packets (such as 520, 1314 and other special amounts), payment records, jewelry luxury purchase vouchers. Individuals cannot directly access another person’s bank statements; however, they may apply to the court during litigation to investigate and collect evidence or to issue an investigation order. As for one’s own Alipay and WeChat transaction records, they can be directly exported and affixed with an electronic certificate.
3. Audio-visual materials (photos, videos, audio recordings): Intimate photos and videos taken in public places (holding hands and cuddling in shopping malls and streets), driving recorder images, surveillance videos of the couple's common residence-pay attention to the legality of the shooting place and method; the recording should be able to identify the identities of both parties in the dialogue, and the content should be complete and not be edited and spliced.
4. Documentary evidence: the guarantee, repentance and commitment written by the other party (stating the fact of derailment and the object have the highest probative power), hotel orders, printed copies of room opening records, express delivery address (sent to the same strange address for a long time), etc.
5. Witness testimony: Neighbors and the property management company confirm that a member of the opposite sex has been frequently entering and leaving; colleagues and friends testify that the two have been publicly engaging in activities as a couple. In principle, witnesses should appear in court to testify and be questioned. If only written testimony is submitted and witnesses are not in court, the probative force is very weak.
6. whereabouts and room opening records: it is difficult for individuals to obtain them by themselves, and they usually obtain them from hotels, platforms and operators by applying for court investigation and evidence collection or investigation orders through litigation; the sources of the internal information obtained by themselves are unknown and may be regarded as illegal.

The purpose of 3. proof is stratified: which step do you want to prove

Whether the evidence of derailment is "enough or not" depends on the purpose of litigation, which is a question that many people do not want to understand:

1. Proof of emotional breakdown (for first divorce suit): as long as there is evidence showing that the contradiction between the two sides is irreconcilable and the other side has the wrong behavior, the standard is relatively low, and the ambiguous chat record plus the record of cold war separation is usually enough to indicate the emotional breakdown;
2. Advocate compensation for divorce damages: The statutory situations listed in Article 1091 of the Civil Code are bigamy, cohabitation with others, domestic violence, abuse and abandonment of family members, etc. Pay attention that "infidelity" itself does not mean "cohabitation with others" -- occasional extramarital sex is hard to fall directly into the statutory compensation situation (some courts discretionary support it with the provisions of "other serious faults"), the evidence must be of a significantly higher standard to demonstrate continuous and stable living together;
3. Claim that the property is less divided or the gift is recovered: according to Article 1092 of the Civil Code and Article 7 of the (II) of Interpretation, if one party gives the common property to a third party for the purpose of violating the duty of loyalty, it can claim to be invalid and return it. At this time, the focus is on the financial evidence of "transferring money to the third party", rather than the emotional details;
4. custody competition: if one party has serious faults or bad habits such as bigamy or cohabitation with others, which will affect the qualification of direct custody (article 14 of the (II)), the evidence requirement is similar to the damage compensation.

In a word: Ambiguous chat can prove "emotional breakdown", the evidence of continuous cohabitation can support "damage compensation", and the flow of funds can support "recovering gifts"-first determine the purpose, then determine the direction of evidence collection, and avoid collecting a bunch of useless materials.

To add a practical observation: Courts tend to adopt a more lenient standard when evaluating evidence of “irretrievable breakdown of the marital relationship,” but apply a stricter standard in determining claims for “damages.” Many parties devote all their efforts to collecting evidence of ambiguous online chats, only to establish that the marriage has irretrievably broken down—far short of meeting the threshold for damages based on “bigamy or cohabitation with another person.” The pragmatic approach is to stratify the use of evidence according to claims: to the extent that it can be proved to claim what rights, do not overestimate the strength of evidence, hard to touch the legal elements.

Construction and fixation of 4. evidence chain

Isolated evidence has limited probative power, and the key is "time line + mutual confirmation": organize the derailment process into a time line (transfer 1314 yuan on a certain day of a certain month → purchase women's bags on a certain day → enter and leave the hotel together on a certain day), so that the evidence from different sources can confirm each other. Regarding preservation methods: For important electronic evidence, promptly go to a notary office to have the evidence preserved via notarization (including the content and the time of its creation). Alternatively, you may use a certified electronic evidence‑preservation platform to obtain a trusted timestamp. In addition to taking screenshots, retain the original storage media, and do not delete any chat records. When giving evidence, it is easier for the court to accept the evidence by organizing and explaining the purpose of each group of evidence.

Obtaining evidence discipline is equally important: don't publicly spread the third party's photos and privacy (which may constitute invasion of privacy or even insulting crime); don't intrude into hotel rooms and other people's houses for obtaining evidence; don't forge chat records or transfer vouchers-forgery of evidence will face compulsory measures such as fines and detention, which seriously constitute a crime.

Organization of 5. evidence and presentation of the trial: let the evidence "be seen"

Gathering all the evidence is only the first step; the manner in which it is organized and presented directly affects its admissibility and persuasive impact.

1. Compile evidence catalogue: divide into groups according to the purpose of proof (emotional breakdown group, fault fact group, property transfer group), and each group is attached with the name, source and proof content of evidence, so that the judge can see at a glance-a stack of disordered screenshots and a clearly numbered evidence book have completely different weight in the judge's mind.
2. Original Documents and Original Media: For documentary evidence, the original document shall be submitted. In court proceedings, electronic evidence should be demonstrated on its original media in real time (e.g., logging into WeChat, reviewing chat records, displaying payment statements). After the judge verifies the original media, the likelihood of the evidence being admitted is significantly higher than when only screenshots are submitted; printouts and screenshots may be used solely as supplementary exhibits.
3. Timeline visualization: arrange the key nodes (the first abnormal transfer, hotel consumption, joint travel) into a table according to time, corresponding to the evidence number, and demonstrate "continuous and stable improper relationship" or "property transfer track".
4. Response to cross-examination: the other party may claim that "the evidence is stolen and secretly photographed", and explain the scene of evidence collection (husband and wife's common residence, public place, export of self-owned account bill) during cross-examination, and demonstrate the legality; if the other party denies the identity of the chat object, it will lock the identity through micro signal, head portrait, voice strip and real name information of transfer.
5. Cost estimation: notarization and preservation (ranging from hundreds to thousands of yuan), application for investigation and evidence collection, legal fees, litigation fees, and budget well in advance; small cases can evaluate whether the "evidence input and litigation income" match, so as to avoid the high cost of evidence collection for small disputes.

also need to prompt the "three" maintenance of electronic evidence: authenticity (not tampered with-by the original carrier and time stamp), legality (legal means of evidence collection), relevance (related to derailment or property claims). Before the hearing, I should review the evidence from the other side's standpoint and put the possible defense ahead, which is much more leisurely than on the spot.

6. Frequently Asked Questions

Can ambiguous chat records prove infidelity?

Ambiguous chatting alone generally cannot directly prove the occurrence of extramarital sex or cohabitation, but it can prove the abnormal relationship between the two parties and the breakdown of their feelings; after the chain is formed by combining the opening records, transfers, witness testimony, etc., the possibility of the court determining the fact of infidelity is greatly increased. If the goal is damages, it is also necessary to prove legal circumstances such as "cohabitation with others.

Is the covert evidence valid?

Those who shoot legally in their own homes and public places are generally accepted; those who shoot secretly in hotel rooms or other people's houses or collect evidence intrusively are suspected of breaking the law, and the evidence may be excluded. The criterion is whether the means of obtaining evidence seriously infringe upon the legitimate rights and interests of others, violate the prohibitive provisions of the law or violate public order and good customs.

How can I obtain the other party’s bank statements and hotel check-in records?

Individuals have no right to directly access other people's accounts and house opening information, so they can apply to the court for investigation and evidence collection or application for investigation order in divorce proceedings; when applying, the object, scope and necessity of the access should be stated, and the court will decide whether to allow it or not after examination.

Is written testimony useful if a witness does not appear in court?

Limited probative power. In principle, witnesses should testify in court and be questioned. If it is really difficult to appear in court (e. g. due to objective reasons such as health and other places), written testimony or remote testimony can only be submitted with the permission of the court, and it is difficult to determine the fact of derailment by relying solely on written testimony, so it is best to use it in conjunction with other evidence.

If you discover that the other party has transferred funds to a third party, can you directly demand the return of those funds?

Can be handled concurrently during divorce: According to Interpretation (II), Article 7, marital joint property gifted to a third party with the intent of breaching the duty of fidelity may be declared invalid and its return may be sought; be sure to preserve transfer records and identity information, and include the third party as a defendant or third party in litigation.

Practical Experience of 7. Lawyers

When taking evidence of derailment, what you fear most is that you can't use it when you get it. Evidence obtained by seriously infringing upon the legitimate rights and interests of others, invading other people's residence or violating the prohibitive provisions of the law may be excluded from the identification, and the parties have made great efforts to get themselves into trouble in the end. Therefore, it is necessary to choose the right method from the very beginning: those that can be obtained through legal means, such as transfer records within the scope of common property, images in public occasions, and guarantees written by the other party themselves, should be collected first; If you need to invade your privacy space or crack your account, don't do it rashly.

You have to figure out where to prove it first. The same piece of evidence has different purposes and different requirements: to prove the breakdown of feelings, as long as it reaches the level that makes people believe that the relationship is abnormal; To claim compensation for divorce damages, the nature and extent of the act should be proved in place against the fault situations listed by the law. If you want to recover the property donated to a third party, the focus will fall on the exchange of money. The goal determines what you should collect, otherwise it's easy to collect a bunch of material that has nothing to do with the claim and get distracted for nothing. Evidence collection should also be conducted in a measured and focused manner—gather evidence that supports your own claims, rather than going to extremes and turning the other party’s life upside down just to get even.

The value of evidence lies in its chain; a single screenshot is rarely sufficient on its own.. A more pragmatic approach is to corrode electronic data, documentary evidence, consumer vouchers and witness testimony into a line around time and character relationships, and pay attention to fixing the original carrier, keeping the complete dialogue context, and avoiding only intercepting fragments. When the trial is presented, it is also necessary to focus on the order and focus, and put out the most illustrative problems first, so that it is difficult for the other party to deny one by one. Finally, a reminder, don't put all your energy on grasping each other's handles. Whether the relationship is broken, the arrangement of property and children is also the key to determining your situation.

The management of derailment evidence can be summarized as "legal acquisition, retention of the original, mutual confirmation, corresponding purpose" four sentences. Specific suggestions: first clarify the divorce claim (divorce/compensation/recovery of property/custody dispute), and push back the evidence collection list according to the purpose; WeChat records keep the original carrier and notarize it in time, transfer records are exported through bills, and the other party's self-admission documents keep the original; All evidence is compiled into a book according to the time line and marked with the purpose of proof. Evidence collection must keep the bottom line of legality. It is better to have less evidence and be legal than to have more evidence and be illegal-illegal evidence not only cannot help, but may also make oneself bear tort liability.
