I don't know what a "court marriage" is. Nor do I understand how the two of them together can have a "guardian." Nor is it clear if the wife who is having an affair is the same woman you're talking about. If your brother is legally married, either one can seek a divorce, whether the other spouse wants it or not. If he was married to someone else at the time he married this "girl", then the marriage was never valid and a decree of invalidity can be entered. In either case, the marriage will end.
