Maintenance plea help

now where is your brother in law staying, if he separate, you can file maintenance case.

My brother in law at times comes home. But never stays at night. But when he is at home, abuses my sister like anything. She had runaway from home with his son couple of times already.

DOn't know how to prove that he is staying away from the home.

sir

Please provide us help in this case. What proofs should we submit and what to claim in maintainance

If your sister herself is not willing to take any action than why do you want to take action . First find out what your sister desires .If her desire is maintenance than go for it and she should not back out of it  . When you aware about bigamy than you must very well be aware about CRPC 125 where she can claim maintenance for herself and her son. Consult a lawyer and go ahead with it . 

Dear Mr. Ramesh, 

If your brother-in-law is not providing any financial assistance, then who are maintaining your sister and her son?  I mean your sister is working anywhere?. If not, she and her son (if he is minor)  can claim maintenance against your brother-in-law. But your sister cannot permit your brother-in-law to enter in their house. If your sister has any strong proof of bigamy (adultry), aparently, she can file adultry case also. Will not destroy your sister's son education by this action of your sister. dont worry. 

But, if any chance is there, try to change your brother-in-law's attitude and behaviour with the help of your elders or any arbitrators. Until take care of your sister and her son.

Bai.
