NTCAT Lease Break Claim — Recovering Costs After Early Termination

A tenant breaks the lease early and moves out. The landlord claims thousands in lost rent, advertising fees, and reletting costs. The tenant argues the charges are excessive or that the landlord failed to mitigate. This is one of the most common disputes to land at NTCAT — and the Residential Tenancies Act 1999 (NT) has specific rules that govern how it plays out.

Lease Break Claims Fall Under the Residential Tenancies Act

If you're a landlord claiming costs from a tenant who broke a fixed-term lease early (or a tenant disputing those costs), your claim goes through NTCAT's residential tenancies jurisdiction, not the general small claims process. The distinction matters because:

• Different fee schedule: residential tenancy filing fees start at $84 for individuals claiming under $2,000, compared to $129 under the Small Claims Act
• Specific statutory notice requirements apply before you can file
• A three-month window applies to a landlord's application to retain bond for lease-break losses — the landlord must apply within three months after the tenant gives up or abandons the premises

You still file using NTCAT Form 1 Initiating Application and select the residential tenancies category, but the governing law and timelines differ from a standard debt claim.

The RT08 Notice — Landlords Must Act Quickly

If the landlord wants to retain part or all of the security deposit to cover lease-break costs, they must give the tenant an RT08 Notice (Notice of Landlord's Intention to Retain Security Deposit) within 7 business days after the tenant gives up vacant possession or the landlord considers the premises apparently abandoned.

The RT08 must:

• Be in the prescribed form
• Specify the amount to be retained and the reason
• Include the required statutory declaration and supporting receipts or other documents
• Return the part of the security deposit not being claimed or held

Under section 112(5) of the Residential Tenancies Act, a landlord is not entitled to retain or continue holding any part of the security deposit unless they meet these requirements within 7 business days. A tenant can apply to NTCAT for return of the deposit if no notice is received within that period, or dispute the amount claimed.

What Landlords Can Claim

Legitimate lease break costs under the Residential Tenancies Act typically include:

• Lease-break loss: for agreements entered into on or after 2 January 2024, the break-lease amount is capped at 28 days' rent if less than half the term has elapsed, or 14 days' rent if at least half has elapsed. The landlord must show actual loss and take reasonable steps to mitigate it. Different rules apply to earlier agreements.
• Advertising costs: evidenced advertising costs may be included in the actual lease-break loss, within the applicable cap
• Reasonable cleaning or repair costs: only for damage beyond normal wear and tear, supported by receipts and condition reports

What landlords cannot claim:

• More than the applicable statutory cap for a lease-break loss under an agreement entered into on or after 2 January 2024
• Excessive or unsubstantiated charges without receipts
• Costs for pre-existing damage or normal wear and tear

What Tenants Can Argue

Tenants disputing a lease break claim at NTCAT typically raise:

• Failure to mitigate: the landlord didn't make reasonable efforts to find a new tenant, or unreasonably rejected prospective tenants
• Excessive charges: the claimed costs are inflated or unsupported by receipts
• Bond already covers it: the security deposit is sufficient to cover legitimate costs, and the landlord is double-dipping by filing for more
• The RT08 was late or defective: the landlord missed the 7-business-day window or didn't provide the required statutory declaration and receipts
• Constructive breach: the tenant left early because the landlord breached the agreement (failed to maintain the property, interfered with quiet enjoyment)

Filing the Claim

For landlords: if you seek to retain bond for lease-break losses, apply to NTCAT on Form 1 under the residential tenancies category within three months after the tenant gives up or abandons the premises. Attach your RT08, statutory declaration, receipts for claimed costs, the original tenancy agreement, and condition reports (entry and exit). The filing fee depends on the amount claimed.

For tenants disputing charges: if the landlord has already filed, you respond with Form 2. If the landlord is withholding your bond without filing at NTCAT, you can file your own application to recover the bond.

Both parties should bring to the hearing:

• The tenancy agreement
• Entry and exit condition reports (with photos)
• The RT08 notice and any response
• Receipts and invoices for all claimed costs
• Evidence of reletting efforts (or lack thereof)
• Bank statements showing bond payments

The Three-Month Rule

If a landlord retains bond for lease-break losses but does not apply within three months after the tenant gives up or abandons the premises, the landlord loses the entitlement to claim all or part of those losses. If you're a landlord, file within that period rather than waiting to see if the tenant will pay voluntarily.
