Also what are her rights with my properties which is still on my father name . Some Property I have given to here that is on her own name . Some Property fully paid by myself is on Joint name . Normally this doesn’t happen when everything is there in place and such fighting I have not understood what is aim is this here behavior what is going to be achieved with this . 14 -15 Years I was thinking that she is fighting for House , Property etc but now its beyond my Imagination .
