Maharashtra tenancies are governed by the Maharashtra Rent Control Act 1999, and most urban arrangements take the form of leave and licence. Section 55 makes registration of these agreements compulsory and places the responsibility on the landlord. Where the agreement was never registered, the tenant's version of its terms prevails unless the landlord proves otherwise.
Karnataka tenancies fall under the Karnataka Rent Act 1999, which requires tenancy agreements in writing and routes certain disputes to the Rent Controller. Bengaluru's practice of ten months' advance rests on custom rather than statute, so the notice relies on the contract itself. On deposits of that size, the pre-suit interest available under the Interest Act 1978 becomes a significant part of the claim.
Tamil Nadu moved early with the Tamil Nadu Regulation of Rights and Responsibilities of Landlords and Tenants Act 2017, which replaced the 1960 rent control law and created Rent Authorities and Rent Courts. Tenancies must be registered with the Rent Authority, and a deposit dispute under a registered tenancy belongs before the Rent Court. Unregistered tenancies should say so candidly, because the forum depends on it.
Uttar Pradesh enacted the Uttar Pradesh Regulation of Urban Premises Tenancy Act 2021, closely modelled on the MTA, with the same two-month residential and six-month non-residential ceilings on deposits. Any excess paid above the ceiling can be claimed in the same notice.
Delhi still has the Delhi Rent Control Act 1958, but Section 3(1)(c) excludes premises above a modest rent threshold, which takes most modern tenancies outside the Act. Deposit disputes therefore go to the civil court, and because the claim rests on a written agreement for a fixed sum, it usually qualifies for a summary suit under Order XXXVII CPC, where the landlord must obtain leave to defend.
