My Father-in-Law is the original tenant for over 40 years and he is occupying a 600 Sqft flat in South Kolkata Area. My Mother-in-law died 9 years ago. My husband is the only son and we are staying with him. We are paying rent as per West Bengal New Tenancy Act and the rent bill is in the name of my father-in-law. Now I would like to know – after death of my father-in-law whether we have any legal right to stay upto five years in that flat ? If yes, then in whose name the rent bill will be issued by the landlady ? or, if the landlady wants can she evict us immediately after the death of my father-in-law? What will be the basis of rent which we have to pay (will it be on the basis of old rent which is my father-in-law is paying ) or landlady can force us to pay new rent ? Please help me by answering my queries at my email id : malabika.basu@yahoo.co.in.
