My late grand father purchased a revenue plot from a registered gpa holder in jan 2003 through a registered sale deed, constructed a shed within one week. We are using the shed for storage purpose from 2003 to present (2024) .No water and electricity connection. The said property was transferred to my father's name by executing release deed in 2011. We are paying tax for the plot for 21 years and using possession peacefully. Now we demolished the shed and started construction of new house.
But Now in 2024 the legal heirs (staying opposite) are claiming that the registered gpa done by legal heirs and their late father is fraud. And the signatures in registered gpa is forged. They are showing RTC and claiming the land belongs to us and stopping construction activities forcefully.
What can be done now and what if the registered gpa is fraud?
