My friend couple stay at Pune India, with one ownership flat in a joint holding. No society formed as only 6 flats. They have made a will, each making each other nominee and post death of both of them, it will be given to their daughter who is USA green card holder.
Is it necessary and enough to register will, without adding their daughter's name in the flat agreement, to have a safe transition to her in case of both parents death or adding her name to property as a third owner is better?
If her name is added (or not added, but mentioned in the registered wills of both), as an owner to the flat held jointly with parents, post both parents' death, can she sell the flat in india and take out money to USA?
