Conclusion: The collection of divorce gambling evidence can start from documentary evidence, audio-visual materials, witness testimony, electronic data, police records, etc., and the collection process should be legal. Legal analysis: According to the Civil Code of the People's Republic of China, if one of the husband and wife has bad habits such as gambling and refuses to correct after repeated education, and mediation is invalid, the court shall grant divorce. Documentary evidence, such as IOUs and fines due to gambling, can directly reflect gambling behavior. Audiovisual materials, like spouse gambling videos and audio, can intuitively present their gambling scenes, but it is necessary to ensure that the acquisition process does not infringe the privacy of others. The testimony of the witness can come from the neighbors and friends who know the situation, and they can confirm the gambling habits of the spouse. Electronic data, such as gambling chat and short message records between spouses and others, can also be used as evidence. The police's police record and inquiry record are the official records of the spouse's gambling being investigated and dealt with, which have strong evidence. Only legally collected evidence can effectively prove the gambling facts of the other party in the court and provide strong support for divorce claims.
