1. Not sufficient grounds to indulge in such legal experiments.
2. Create grounds (situation) so that Law takes its due course.
A. She should have filed some proceedings in a Court where you can produce available ‘media’ necessitating rent in lieu of right to live under same roof for safeguarding ‘social / family harmony’.
B. If you have guts then file ‘divorce’ suit against her living under same roof under ‘cruelties’ and win it so that she upon hearing Decree in a Divorce proceedings leaves the matrimonial home forever.
C. Ask her how much it will cost you to divorce her and if her financial demands meets your capacity then proceed under MCD and part ways.
D. If both of you are not facing any legal activity from each other in any Court then transfer deed self acquired property in name of your mother and in due course of time ask mother to approach Court with ‘media proofs’ that you have as per your brief to ‘evict’ both her son (that is you) and her DIL under remedy of a Protection Order available under DV Act to her.
PS.: If you are asking this question again with new twist then I see you are not upto legal standards to get rid of legally wedded spouse on your own standing, hence, leave alleged matrimonial facts in the hands of paid legal professional to handle such matters on your behalf, which naturally takes its own due course and does not happen overnight unless ‘C’ is looptail here. No PM to me on my reply.
