What evidence do you need to catch mistress?

Legal analysis: 1. E-mail and chat history.

Ensure that the correspondence, email or chat records between the other party and the third party remain unchanged. In the process of extracting e-mail or chat records, it must be notarized by the notary office. Evidence of extramarital affairs, such as e-mail or chat records extracted by the court when suing for divorce, is difficult for the court to accept.

2. Letter of guarantee or repentance. At the beginning of extramarital affairs being discovered by the other party, some people will write a letter of guarantee or a book of repentance to show their determination to "never do it again" in the future.

Third, photos. Because the evidence of extramarital affairs should be legally obtained, if a detective company is invited to take photos, the understanding of extramarital affairs evidence should be carefully investigated in the operation process to ensure the legitimacy of extramarital affairs evidence, thus achieving the purpose of providing effective evidence of extramarital affairs when the court divorces.

Fourth, video recording. If the video taken by the parties in public can be used as evidence, if it is taken secretly, only the video taken in their own home can be used as evidence, while the video taken in the hotel through surveillance video and taken in other people's homes can not be used as evidence.

Verb (short for verb) recording. When a husband and wife negotiate about an affair, the recorded data are mainly collected by the parties themselves, and there is no need to inform the other party.

Legal basis: Some provisions of the Supreme People's Court on evidence in civil proceedings.

Article 2 The parties have the responsibility to provide evidence to prove the facts on which their claims are based or to refute the facts of the other party's claims. If there is no evidence or the evidence is insufficient to prove the facts identified by the parties, the parties with the burden of proof shall bear the adverse consequences.

Article 10 When providing evidence to a people's court, a party shall provide the original or the original. If it is necessary to preserve the original and original evidence or it is really difficult to provide the original and original evidence, a copy or duplicate verified by the people's court may be provided.
