Sir, A power of attorney was executed by seven legal heirs of a deceased person in respect of their ancestral property (land) in favour of two persons say, A and B in the year 1994 for sale etc. In the year 1997, a portion of the said land was sold to C on the strength of the said power of attorney under a valid deed of sale but the sale deed was executed only by A. Is the sale deed valid or is it to be executed by both A and B.
