The owner of certain premises let it out to tenant for a period of five years. The parties executed a lease deed, which was not registered. One of the terms of the said lease deed permitted the tenant to sub-let the premises to his friend Mr. 'X', if the tenant so desired, without the prior consent of the landlord. The tenant sub-let the premises to his friend Mr. 'X' without taking prior permission of the landlord, on which the landlord filed a petition for eviction. The tenant contends that in view of the term of the lease, he was well within his rights to sublet. The landlord contends that the lease deed having not been registered cannot be looked into. Decide.

The Governing Provision — Section 17(1)(d) and Its Consequence Under Section 49

Section 17(1)(d) of the Registration Act, 1908 makes compulsorily registrable every lease of immovable property from year to year, for any term exceeding one year, or reserving a yearly rent. A lease for five years falls squarely and unmistakably within this provision — indeed, the Supreme Court in Anthony v. K.C. Ittoop & Sons identified this precise scenario as involving a "three-pronged statutory inhibition": the first limb of Section 107 of the Transfer of Property Act (mandating registration for such leases), Section 17(1)(d) of the Registration Act (making registration compulsory), and Section 49 of the Registration Act (rendering the unregistered document ineffective).

Section 49 provides that no document required to be registered under Section 17 shall — unless registered — affect any immovable property comprised in it, or be received as evidence of any transaction affecting such property. The proviso carves out two exceptions: the document may still be used as evidence of a contract in a suit for specific performance, or as evidence of any collateral transaction not required to be effected by a registered instrument. Neither exception assists the tenant here, since the eviction proceeding is not a suit for specific performance, and the subletting clause is not a "collateral" matter — it is a substantive term of the very lease that required registration.

Why the Subletting Clause Cannot Be Proved — "Terms of the Lease" Are Not Collateral

The critical legal proposition governing this case is that the terms of a lease are never treated as a "collateral purpose" for which an unregistered document can be admitted in evidence. The Supreme Court, in Satish Chand Makhan v. Goverdhandas Byas, held that where a lessee remained in possession under an unregistered deed of renewal of lease, that deed was inadmissible except for the limited collateral purpose of proving the nature and character of possession — it could not be admitted to prove the transaction of lease itself, since the terms of a lease do not qualify as a collateral purpose within the meaning of the proviso to Section 49.

This principle has been repeatedly reaffirmed. It has been held that rent reserved by an unregistered lease cannot be proved by oral or documentary reliance on the unregistered instrument, because rent is a term of the lease; similarly, it has been held in a Delhi case that "terms of the lease are not a collateral purpose," and even payment of stamp duty afterward will not cure this defect. A subletting clause — a specific covenant permitting the tenant to create a sub-tenancy without the landlord's consent — is, in exactly the same way, an intrinsic term of the lease itself, not a matter merely incidental or collateral to it. It cannot, therefore, be proved by producing or relying upon the unregistered lease deed.

Application to the Present Facts

The tenant's defence rests entirely on a specific clause of the unregistered five-year lease deed — the clause permitting him to sublet to Mr. X without the landlord's prior consent. Since this clause is a term of the lease strictly requiring registration under Section 17(1)(d), and the lease was never registered, Section 49 bars the tenant from relying on that document, or that clause within it, as evidence of his authority to sublet. The tenant cannot selectively invoke one favourable term of an otherwise inadmissible document while ignoring the statutory bar that attaches to the document as a whole; the terms of the lease, including this particular covenant, simply cannot be proved through the unregistered instrument.

The Residual Legal Effect of the Unregistered Lease — Month-to-Month Tenancy

This does not mean the transaction between the parties is a nullity, or that the tenant is a trespasser without any legal status at all. As the Supreme Court explained in Anthony v. K.C. Ittoop & Sons, non-registration of a lease exceeding one year produces two distinct consequences: first, no lease exceeding one year is created; and second, the instrument becomes wholly useless for the purpose of creating that particular lease. However, where the tenant has been let into possession and has paid rent, the jural relationship of landlord and tenant still exists on the strength of conduct — falling within the second paragraph of Section 107 of the Transfer of Property Act — and gives rise, by presumption, to a lease not exceeding one year, ordinarily construed as a monthly tenancy.

Crucially, such a monthly tenancy arising by operation of law and conduct carries with it none of the special covenants that were sought to be created by the unregistered instrument — including the subletting clause. A tenancy-at-will or a statutory month-to-month tenancy does not, by default, carry any right to sublet without the landlord's consent; such a right, if it is to exist, must be traced to an enforceable term of a valid lease. Since the subletting clause cannot be proved due to the bar under Section 49, the tenant is left with only the bare, minimal incidents of a monthly tenancy, which does not include an unrestricted right to sublet.

Illustration

If A leases his shop to B for five years by an unregistered deed containing a clause permitting B to sublet to his friend X without A's consent, and B does sublet to X, A may seek B's eviction on the ground of unauthorised subletting. B cannot defend himself by pointing to the subletting clause in the unregistered deed, since Section 49 bars that clause — like every other term of the lease — from being received in evidence to establish B's contractual right to sublet. B's possession, at best, continues merely as a presumed month-to-month tenant by virtue of delivery of possession and payment of rent, and no such implied monthly tenancy carries within it a right to sublet without the landlord's consent. A's petition for eviction, grounded on unauthorised subletting, must therefore succeed.

Rejecting the Landlord's Broader Contention

It is worth noting that the landlord's contention — that the lease deed "cannot be looked into at all" — is broader than the law actually permits, though it does not affect the outcome. The correct legal position is not that the document is entirely unusable for every purpose, but rather that it cannot be used to prove the terms of the lease itself, including the disputed subletting clause. The document could still be looked into for genuinely collateral purposes — for instance, to show the nature and character of the tenant's possession, or the date on which possession commenced — but proving the tenant's contractual entitlement to sublet is not such a collateral purpose; it goes to the very essence of the leasehold terms that required registration.
