My maternal grandparents have always hated my mother since she married my father out of her own will. Since then, they cut her out of their life by all means and purposes. Unfortunately, the marriage between my parents didn't work out (due to my father's indulgence alcoholism and other family issues) and they got a divorce after about 20 years of marriage. They lived separately for a period of 7 years before that as well. During that period my mother went through terrible times financially. My maternal grandparents didn't even let her stay in their home when she was sick and I was a child. They gave her no money either. They have always made her feel less both financially and stature wise in comparison to their son - who was the only child they ever wanted.
By god's grace things are good now and we have a happy life. We never kept any contact with them, and neither did we want any. But a few months ago we got to know that they had legally disinherited my mother from their self-earned property. Now, just to clarify - my mother doesn't want a part in their property and never has. But getting that news was an awful blow to her. Despite everything that happened she still had some attachment with her parents (who doesn't) and never thought they would go to such an extent to cut her out of their life. They gave 80% of the property to their son and 20% to their other daughter (My Maasi). They have disinherited her just to show her her place.
They took out a notice in the newspaper about it but we didn't get any copy/notice of it. We don't even know when it was done. From what I have read, if parents prepare a will and specifically mention that one child has been disinherited, the child cannot claim any right to the property. We know there is a will but we don't know if they have judically disinherited my mother or if they have simply taken out a notice in the newspaper.
My question is - do we have any legal discourse here? If my mother wants to take them to court - what can she do?
