Following the death of the original tenant, tenancy rights in West Bengal typically pass to the family members (wife and sons in this case) who were residing with them at the time of death. These individuals are generally considered the new tenants and inherit the rights as per the West Bengal Premises Tenancy Act. While the rent agreement's terms are important, the law provides for the devolution of tenancy rights to legal heirs, though compromises with the owner are also possible.
