Dear Sir,
we purchased a land from Mr. M about 20418 Sq ft.
Land is situated on higwaty and it is agriculture land.
We registered the land in our name and also anantkal in our name.
After sale of peoperty son of M taken stay from court on that land and they taken possition on that land. As per Son of M land belong to his grand paa and they also entiteld in equal share with Mr. M (Father).
(One problem we know that Mr. M has two borther and land ofLand still is in the name of His fathers name. they just share amount htemselves and doing agriculture activity on thier share as mutualy decided)
My Question is that:-
1) we can loss this land in any fact ??
2) is grand sons have right on this property??
3) when we have registry what we do now ??
Regards
