My sister is married for 20 years now and has a son. The son is 18 years old. She is housewife and totally dependent on husband. my brother-in-law has affair and seems like he has got married to that girl via registered marriage.
I am aware that this is case of bigamy and we can seek criminal actions against him. But the point is my sister is not willing to take the action , as her son's education will get impacted. He at this point needs funding for his education. Her priority is to guarantee her son's education.
my brother-in-law is barely gives money for family maintenance. The son needs lot of funds now for education.
What could be best possible approach here. Without taking any criminal action and impacting the son's education.
