Sir i am not law Expert ! Sir in NCR and Delhi all Builders are doing Rs 50 / 100 Allotement or Agreement or Memorendum agreement and on the basis of this sale deed is done later on which is then registered and stamp duty paid. Are these transactions are wrong ? What concen me is that when project is in construction. and full payment has not been done ,how can one pay full 5 % duty on full consideartion or on 90 % amount as no rights are transfer
