Transfer of Property Act, 1882
115. Effect of surrender and forfeiture on under leases
The surrender, express or implied, of a lease of immovable property does not prejudice an under lease of the property or any part thereof previously granted by the lessee, on terms and conditions substantially the same (except as regards the amount of rent) as those of the original lease; but, unless the surrender is made for the purpose of obtaining a new lease, the rent payable by, and the contracts binding on, the under lessee shall be respectively payable to and enforceable by the lessor.
The forfeiture of such a lease annuls all such under leases, except where such forfeiture has been procured by the lessor in fraud of the under lessees, or relief against the forfeiture is granted under section 114.
