Do you need a witness's signature for the evidence of cheating?

No need. To catch cheating, the first thing is electronic evidence. For example, SMS records of spouses and affair objects, WeChat chat records, etc. Considering the particularity of electronic evidence, in order to ensure its probative power, it is best to entrust a notarization institution to notarize it in time.

Followed by documentary evidence, mainly including:

1. Written confession, confession, guarantee and agreement signed by the spouse.

2. Police records and transcripts that can prove each other's infidelity.

3. Handle the documents issued by the other party's work unit that can prove that the other party is having an affair.

4. Eyewitness testimony.

5. It is audio-visual evidence, including audio, video and photos.

Provide three methods for your reference:

1. The injured party should not quarrel with your spouse, but talk to him strategically and say that he should be given a chance to admit his mistake. You can record during this period as evidence for future litigation. If you can, you can also ask him to write a repentance book, stating his relationship with whom. This is a more direct evidence.

The injured party can move out for a period of time. In the meantime, you can install video equipment at home, and sometimes you can record a lot of useful evidence, but it is not illegal to install video equipment at home, so it is a good method. In addition, you can also pay close attention to their actions and find that they enter your house together at night and turn off the lights to rest. You can find more than two people to go home with you, nominally taking things but actually taking pictures of rape.

3. If they are found to have sex in other places, they can report prostitution to the Public Security Bureau, and the transcripts captured by the Public Security Bureau at the scene can be used as evidence of "extramarital affairs".
