A, B, C, and D executed an Irrevocable General PoA to an Agent Y for sale & development of their land in Nagpur in 2004. All are Hindu. A and B had 29 R, C had 1.81 H, & D had 1.81 H.
A & B died in 2007.
1) Does the PoA gets cancelled automatically?
2) If automatically cancelled, is there a need for public notice or any other process?
3) If C & D do not cancel the PoA and the agent Y sells 20 R from C's part in 2013, is it considered legal?
4) Which act clarifies these queries?
