On 11 October 2021, the Real Property Amendment (Certificates of Title) Act 2021 commenced, which abolished the Certificates of Title (CTs) and the control of the right to deal (CoRD) framework. All existing CTs have been cancelled and CTs will no longer be issued. Existing CTs will not need to be produced, and CoRD holder consent will not be required, for a dealing or plan to be registered. All existing Guidelines subject to this change are currently being reviewed and will be updated to reflect these changes. For further information regarding the abolition of CTs, please see https://www.registrargeneral.nsw.gov.au/property-and-conveyancing/eConveyancing/abolition-of-certificates-of-title

Variation of Sublease

This page aims to help you complete an electronic Variation of Sublease dealing form. This form is used to register a variation in the terms of a registered sublease.

A Variation of Sublease dealing form may be used when a registered sublease is being varied:

  1. to increase or reduce the rent payable under the sublease or
  2. to increase or reduce the period for which the sublease is to have effect or
  3. to otherwise vary, omit or add to the provisions of the sublease in accordance with section 55A Real Property Act 1900.

NOTE: A Variation of Lease dealing form must be used to vary a lease. 

The land or premises affected by the sublease, or the parties to the sublease, cannot be varied by this dealing.

NOTE: A variation of sublease affecting a sublease carried forward as a subsisting interest, i.e. 'Bk ... No. ... Lease To ...'  must be lodged as Dealing with Exception.

A Variation of Sublease may be registered after expiry of the sublease provided that:

  • the sublease is still recorded on the Register and
  • the sublease expired less than 12 months ago. A variation of a sublease that expired more than 12 months ago will not be accepted and
  • the variation extends the term of the sublease so that it is current at the time of registration.

A variation of a current sublease may decrease the term providing the sublease is still current at the time of lodgment.

NOTE:  The term cannot be varied to exceed 5 years, including any options, where the mortgage is not exempt from section 106 Conveyancing Act 1919. Where the term exceeds 5 years a statutory declaration is required stating the lease does not contravene section 106 Conveyancing Act 1919.

NOTE: Both the sublessor and the sublessee must be represented in the workspace for this dealing form.
