We have applied for AMC Prathan mantri Aavas yojana in my wife's name under reserve category of Baxipanch.we have submitted Baxipanch certificate which is issued in my name as a proof of cast certificate. She is selected in the draw of AMC. Now my querry is that Baxipanch certificate issued to me is valid to use for my wife or not.
