A lease term is the agreed period a lease runs, from the commencement date to expiry, which sets when rent or rentals are payable and when the lease can end.

Also known as: lease duration, rental period

Key points

  • A fixed term has set start and end dates; a periodic tenancy rolls on weekly, fortnightly or monthly until someone gives notice.
  • Some terms carry an option to extend, exercised by written notice inside a stated window: see renewal option.
  • A break option lets a party end the lease early, usually on strict notice and conditions.
  • Staying on after expiry, known as holdover, usually creates a periodic tenancy, often at a higher rate set out in the lease.
  • For accounting, the term includes extension periods the lessee is reasonably certain to take up.

Frequently asked questions

What happens if a tenant stays after the lease ends?

The tenancy usually becomes periodic, known as holdover, and the tenant stays liable for rent and the other obligations. Many leases set a higher holdover rate and let the landlord end the arrangement with notice. Express holdover wording saves an argument later.

Can a landlord increase rent during a fixed term?

Generally not, unless the lease expressly allows a rent review or escalation during the term. Residential tenancy rules can also limit increases. In commercial leases the review clause governs the timing and the method, so read it before you sign.

Can a lease be assigned part way through the term?

Yes, subject to the assignment clause and any landlord consent it requires. The assignee takes the remaining unexpired term, so the end date does not change unless the parties novate the lease. The original tenant may stay liable, depending on the wording.

Does a long lease have to be registered?

Many long leases must be registered to be effective against third parties, and an unregistered one risks priority and enforcement problems. Registration rules are set by each state or territory land registry, so check the guidance that applies where the premises sit.

How does a break clause affect lease accounting?

If the lessee is reasonably certain to exercise a break option, the accounting lease term can be shortened, which reduces the right-of-use asset and the lease liability. The opposite applies to extension options the lessee is reasonably certain to take up.
