Transfer of property

I have bought an industrial Plot in Mohali Punjab from one person Ashok who was originally agreement holder to janta promoters and builder LTD (JLPL). The allotment was pending. The balance amount was paid by me to JLPL through bank. Ashok had given me sales deed, a GPA and a will which were registered. Now when I have received the allotment letter and I asked JLPL to get the property transferred in my name they are saying that I cannot have the property registered in my own name and the property registration would be done in name of Ashok first and then re-registered in some one’s name I may wish to (my wife or son). Pls help and guide. My query 1 can I transfer the property in my own name being a gpa holder? 2. Is it necessary to register the property in the name is Ashok first and then get it re-registered Ps : the property is rera registered and the allotment letter reads “Priyank (my name) GPA holder of Ashok”. The details goes to industrial department as per JLPL
