Preventing family members from selling ancestral land

Immediately visit to the village with a draft of gift deed and get the property registered in your name or in some one's name as expeditiously as possible.

You file a civil suit in civil court praying for  permanent injunction restraining your brother and nmother from selling the property to anyone. After filing the suit you apply for temporary injuntion or stay of proposed property sale by your mother and brother pending  final disposal of you rinjunction case. You file the suit under order 37 cpc for summary trial of the suit  which may expedite hearing of your case. If you appreciate this answer  please click the thank you button on this forum.

what i am getting the understanding here is even if my elder brother signs the deal on his own. i can not object the deal(i can not file a complain against it ) only my mother has that right.

i have to depend on luck on whether i can stop my brother from selling the land in court.

is there not some agreement clause for the partners where if they disagree except my mother no one else can sell the land

You  bought that land some 28 years ago on your mother's name. If she equally loves yopu you ask her to transfer back the property in your name by  a registered gift deed. IN which case youu'd become absolute owner of the property. You immeidiately approach your mother and by cajoling and  raking up her motherly instinct fo ryou make her transfer back the proertry in you rname. The sooner it is made the better it would be.Have you got any written proof that you invested your own money in purchasing that land and transfered it in you rmother'sname? PLease gather all  that evidence before approaching a court.It would help you in succeeding in  the Injunction  suit against you rmother and elder brother.
