Saurabh,
In my view I see that ther could be 2 ways you can do this, and in both way bank need to agree for the same, builder may be fine as there may not be any issues from his side.
Method 1
- You need to approach the bank from where you have taken loan with NOC from your dad to remove his name. When bank agrees for the same then it is a simple work to finsih your task. Bank may ask you provide fresh agreement to sale document from builder having your name alone.
- Next approach the builder with need to have fresh agreement of sale with your name alone.
Method 2
- Wait till property consturction gets completed, once it is ready for registration, talk to bank and say that you would like to register the property only your name excluding your dad's name. Ask NOC from bank side to register without your dad's name, builder may need this doc.
- Register the property in your name and get the final sale deed to bank.
thanks,
