1. The three daughters can not acquire the ownership of the house if the house was not willed, settled or gifted in their favout legally,
2. You can not stop others to file a partition suit. You shall have to contest it,
3. Why should you prove that the 1st house was not gifted to the eldest daughter when it was gifted to her through execution and registration of a gift deed? It is not possible either,
4. The 1st house has already been gifted to the eldest daugher for which it has become her property. Under no circumstances, you can now lay your claim on any share of the 1st house.
