This is a frequently disputed issue between landlords and tenants in Mumbai, and the clear legal position is that a tenant generally cannot sublet rented property without the landlord's explicit permission, and doing so unauthorized can expose the tenant to serious consequences, including eviction, depending on which legal framework governs the specific tenancy. Under general principles of the Transfer of Property Act, 1882, and more specifically under the Maharashtra Rent Control Act, 1999 for properties covered by rent control legislation, subletting without the landlord's written consent constitutes a clear ground for eviction.

Section 16 of the Maharashtra Rent Control Act, 1999 specifically addresses unauthorized subletting as one of the enumerated grounds on which a landlord can seek possession of the premises from a protected tenant, recognising that the landlord-tenant relationship is fundamentally personal in nature, based on the landlord's trust in the specific tenant they agreed to let the property to, and allowing unrestricted subletting would undermine this foundational relationship by introducing occupants the landlord never actually agreed to accept. This applies with particular force to residential tenancies where landlords often have legitimate concerns about who occupies their property.

Where subletting has occurred without permission, the landlord can initiate eviction proceedings before the Small Causes Court in Mumbai, which has specific jurisdiction over rent control matters, seeking possession on the specific ground of unauthorized subletting under the applicable provisions of the Rent Control Act. The landlord must generally establish that genuine subletting occurred — meaning the original tenant transferred exclusive possession and control to a third party in exchange for consideration — as opposed to merely allowing a family member, guest, or paying guest arrangement that doesn't constitute subletting in the strict legal sense, since courts distinguish carefully between genuine subletting and other forms of shared occupation that don't violate the tenancy terms.

Where the original rent agreement or tenancy terms explicitly permit subletting with prior written consent, and the tenant has obtained this consent before subletting, this arrangement remains legally valid and doesn't expose the tenant to eviction risk, making it essential for tenants who genuinely need to sublet to formally seek and document the landlord's permission rather than proceeding informally and risking their tenancy. Landlords, for their part, should ensure their rent agreements clearly address the subletting question to avoid ambiguity that could complicate future enforcement.
