my father bought a house on pagdi system in 1965.After his death in 1996 I along with my mother are residing there until now.In the past the landlord has refused to transfer the rent receipt in my moms name and also stopped taking the rent. I have sent him the rent by cheque which he has not encashed. Now he has sold the property to a buildr who is [planning to redevelop the property.
what are my rights in this case? Also, can my married sister claim a share of the property?
