About this underlease agreement
This document allows you to carve out a sub lease from a head lease with the same terms, or alternatively, to specify different terms and impose further obligations on the new tenant. Using this template, your agreement can follow or deviate from the original as much as you like.
Typically, this document would be used by the tenant under the original head lease, in order to sublet:
- part of the property to a subtenant, while the original tenant continues to occupy the rest of the property;
- the whole property, split into separate units, to multiple tenants (perhaps at relatively higher individual rents so that the original tenant profits);
- the whole of a property to a single new tenant so that the original tenant is effectively replaced by the new subtenant.
This agreement is suitable for any commercial property including office buildings, shops, industrial units such as workshops, warehouses and factories, and even land. Because underleases deal with legal issues in the round, the form of underlease required for a shop on the high street is not different from the form required to sublet a scrap yard.
If you are subletting only part of the property you will need to look afresh at how responsibilities such as service provision, access, insurance and so on are split between the head landlord, you the sublessor and your subtenants. We provide for many different possible options. This is a very flexible document.
The underlessor should first check the original lease. Subletting may be allowed and if so, the permission is likely to be subject to specific conditions. If not allowed, you will have to go to the head landlord and negotiate. For example, it may be possible, with the landlord's consent, to increase the rent under the head lease in return for allowing subletting.
Plain English is used throughout except where it is necessary to use legal terms common in land law.
The key features of this template can be summarised as:
- new guarantor;
- provision for premature termination: break clause;
- rent review options.
This sublease is one of a collection of commercial lease templates designed for use by property professionals: experienced landlords, solicitors and surveyors. Accordingly, the provisions are very thorough.
The law in this underlease
Most commercial leases are governed by property laws which are similar from one state to another. The exception is retail leases, which are subject to state/territory retail lease law. If the term of this lease is longer than three years it must be registered. A sublease carved out of a registered head lease should itself be registered.
Alternatives to this document
We offer two underleases. This version will be used for most situations. The alternative is for circumstances where the head landlord has required deeper and more detailed involvement in the relationship between himself and the new subtenant. You may be interested to look at: Sublease agreement for commercial property: landlord involvement.
Note that this document is not suitable for subletting residential tenancy agreements. In those situations, we recommend cancelling the original and using a new tenancy agreement to let the property to the new tenants.
