Padgi flats in mumbai

We have pagdi flats in my late father's name and the rent receipts are in still appearing in my father's name. now my mother has decided to dispose the flats and share the sale consideration after paying the landlord the transfer fee to all the children equally. Is here a law where the portion of the sale consideration in a pagdi flat is apportioned in percentage equally or my mother has a higher share than the children in this kind of non ownership flats. if yes, what is the breakup in percentage. example : my father died without making a WILL.
