Property - Transfer of Ownership

My query links exactly with the same category mentioned in the Noida Authority Website as: “Permission for transfer of plot on demise of the allottee to his legal heir who has not left any Will / or has left un-registered Will and plot is being transferred with mutual consent of all the legal heirs” Religion: Hindu (As asked from yourside) So, at the time while filling up the application form for the allotment of a plot, the names that he (my Dad) had mentioned on that basic form, included the name of beneficiaries in it were not matching with the name of his real wife and children (me, my two sisters and my mother). Though, the concern rises as he might had done a second marriage also, which cannot be realistic at all. Now, whatever he was thinking / doing at that time while filling up the form or what he had done unknowingly as just blink of an eye hit, resulted in the form of not showing our names. So, please help in tell the steps to be followed in this case.
