Thank you for your reply Mr. Hemant
1. It would depend on who (B1 or B2 or Wife of B1) paid the purchase price for the plot of land.
---> AS Far as we knew there were no records who paid for the purchase price...,but even though it was paid,the money came from the earnings on the agriculture land crops , both co-owned by B1 and B2.
2. In any case since B2 & family down-the-line is in & would be in Adverse possession, life long. The land and the B2's building is safe life-long in the hands of B2 & family.
--> Did not quite understood Sir, please bear for that. Adverse Possession. but is it on the other hand how B2's buildling is safe in hands of B2 & Family when as Adverse Possession.
3. B2 & family SHOULD Continue paying all the taxes and preserve receipts and any other documents that may be available.
--> B2's family is still paying since 25 years or so and thanks for your suggestion, B2's family will collect from the respective payments receiptsfrom now on and let 'em gather old ones.
4. Locate the "Funding evidences" for construction of B2's house and preserve for projected future litigation.
--> As raised in point 1 , money came from the agricultural land both co-owned and assumption was that there is no record, unless made up.
Thank you very much for your suggestions.
Keep Smiling .... Hemant Agarwal
