Section 80

A lease of registered land may be surrendered —

A surrender shall be registered by endorsement of a memorial on the folio of the land-register or any instrument of title for the reversion.

Registration of the surrender (whether consequent upon merger or otherwise) of a lease which is subject to a sublease does not extinguish the sublease, but the Registrar shall endorse a memorial of registration of the sublease on the folio of the land-register or other instrument of title for the reversion on which he registers the surrender, and the estate evidenced by that folio or other instrument shall, to the extent and for the purpose of preserving such incidents and obligations as would otherwise have subsisted, be deemed to be the reversion expectant on the sublease.

An instrument of surrender shall be executed by the lessee and by any mortgagee or chargee of the term and shall be accepted by the proprietor and by any mortgagee or chargee of the reversion.

A proprietor seeking registration of a surrender by operation of law shall apply in writing to the Registrar, and shall support his application by such evidence as the Registrar may reasonably require.[76
