My Grand Mother have wrote a deed mentioning that She is giving 6acres of the land to my auny from the Joint property ( Joint property of myself, my Mom and My Sister) of 16 Acres. This false/focus deed was wrote and registered by her on 2003. Since the land was not in her name this deed is not valid. kindly advise me the procedure for the cancellation of that false deed and how much cost involved in it?
