Then after D has raised objection on such false sale deed while the revenue authorities has cancelled all the entry pertaining to such sale deed. Then D has lodge the civil matter to cancel the registered sale deed while in the proceeding Mr A has entered and confessed by the judicial affidavit that he has the right to sale the share of A,B and C on the legal power of attorney. and he had willfully sale and sign sale deed of X and Y then as a witness he had made a sign on sale deed of W and Z. But on the ground of joint property was of 4 person A,B,C and D but the D has not given any authority to sold the said property hence both the registered sale deed has been cancelled by the civil court judge. Now D has lodged claim in the civil court saying that the A has already willfully waved off his right over property by making registered sale deed also he is as a witness in the second sale deed confessed in the court that the selling of property share is his right. The suit is under process in the court. So I need your kind help to guide us can the court will consider the argument of D and will order to remove share of A,B and C from the said land property.
