Investigation and evidence collection for the crime of bigamy, how to conduct the investigation and

The offence of bigamy requires the following evidence:

2. Cohabitation in the name of husband and wife without obtaining a marriage certificate: In this case, because there is no direct evidence like the previous situation, it is more troublesome to collect evidence, and the specific evidence that can be collected includes: the witness testimony of friends, the guarantee of one party to the extramarital affair, the confession, etc., the ** video of the two parties in and out of the extramarital affair together, and the intimate text messages sent by both parties.

Methods of investigation and evidence collection for the crime of bigamy:

1. Investigate and secretly visit the places where they live and live.

The most important point to determine bigamy is to live with another person, so the place of cohabitation is very important, and only when a place to live together can there be further marriage investigation and evidence.

2. Establish a good relationship with the people around the bigamist's place of life.

Whether or not a bigamist is really bigamy depends on whether he is living with another person in the name of husband and wife, and this requires the approval of someone, so the words (approval) of these people are important evidence that must not be missing.

3. Call the police, please investigate.

4. Go to the marriage registry office to check the marriage status of the party having an extramarital affair. If there is a registration, the staff of the civil affairs department may be requested to cooperate in obtaining evidence of bigamy.
