We had given our old house for development to a builder in Bangalore. old house jointly owned by 4 siblings. As per JDA with builder we will get 4 flats. JDA is notorized not registered. Construction is complete and builder has sold their share of flats. The 4 siblings have to get ownership of their flats(one each). What is the procedure to secure each ones share. Do we have any dependency on the builder ? Pls enlighten us. Thank you.
