By both the lessor and the lessee.

According to Section 107. Leases how made

A lease of immovable property from year to year, or for any term exceeding one year or reserving a yearly rent, can be made only by a registered instrument.

All other leases of immovable property may be made either by a registered instrument or by oral agreement accompanied by delivery of possession.

Where a lease of immovable property is made by a registered instrument, such instrument or, where there are more instruments than one, each such instrument shall be executed by both the lessor and the lessee:

PROVIDED that the State Government from time to time, by notification in the Official Gazette, direct that leases of immovable property, other than leases from year to year, or for any term exceeding one year, or reserving a yearly rent, or any class of such leases, may be made by unregistered instrument or by oral agreement without delivery of possession.
