When purchasing a property from legal heirs, it's important to clarify ownership and documentation. In this case, the property was inherited by two daughters who have since partitioned it with separate deeds and khata numbers. While the daughters are the competent sellers for their respective portions, their children's signatures are generally not required for the sale. However, it's advisable to consult a property lawyer to ensure all legalities are correctly handled and to determine if separate sale deeds are necessary for each portion.
