'X' has given power of attorney (registered) of his own land to his brother 'Y'. The next month, 'Y' has made a will deed (unregistered) to his daughter and made a notary of the will deed. The will deed was signed by 'X' as a witness. The next year 'X' died.
Kindly clarify -
(1) Is the power of attorney valid after the death of 'X' ?
(2) Is the Will valid made by POA holder ?
(3) Does 'Y' have the right to sell the land ?
(4) If 'Z' wants to buy that land, what documents are to be collected and verified in this case ?
