If there is evidence that his wife has cheated, he may not ask his wife for compensation.
Because according to the law, only when it constitutes bigamy or cohabitation with others, the derailed party needs to compensate the innocent party, and other cases of derailment do not need to compensate the other party.
[Legal basis] According to Article 1091 of the Civil Code, if one of the following circumstances leads to divorce, the innocent party has the right to claim damages:
（1） Bigamy;
（2） Cohabitation with others;
（3） Domestic violence;
（4） Abuse or abandon family members;
（5） There are other major faults.
