Dear Bala / Kumar,
After going through your queries and replies here in, I am of the view that you both are out ceiling of rent act / rent control act of your state/ city. As per Trasnfer of Property Act notice is must before eviction. You both are paying rent through cheques and landlord is not issuing rent reciepts even then you can prove that you are paying rent. Lease / tenancy under rent act/ rent control can be terminated. when you are out ceiling of rent act / rent control act then tenancy / lease can be terminated and in absence of any registered rent agreement / lease deed, tenancy can be terminated under section 106 of T.P.Act by giving 15 days notice. You would not have any remedy but to linger on case on one pretext or other or would get time from court by giving undertaking that you would vacacte after specific periold. The tenant has no defense after recent judgments of supreme court in rent law / transfer of property act.
