What Makes a Termination Notice Invalid in NSW? Common Landlord Mistakes

A material defect in a termination notice can lead NCAT to dismiss the landlord's application. If the landlord must serve a fresh notice, the full statutory notice period runs again. For a 90-day notice, that can cost three more months.

Here are the defects that actually cause notices to fail at the Tribunal.

Defects That Can Put a Notice at Risk

Missing Termination Information Statement. Every termination notice must include the prescribed Termination Information Statement published by NSW Fair Trading. This is a separate document — not part of the notice itself — that informs the tenant of their statutory rights, the grounds framework, and how to challenge the notice. Omitting it can make the notice invalid; whether NCAT can make an order despite the defect depends on the section 113 test.

No supporting evidence attached. Since May 2025, many grounds require specific supporting documents or information: a contract for sale, a signed landlord statement, or development consent when required. Serving a notice that states one of these grounds but omits its required evidence can leave NCAT without the material needed to make a termination order.

Wrong vacate date during a fixed term. For non-fault grounds, the vacate date cannot fall before the last day of the fixed term. If the date in the notice is earlier than the fixed-term expiry, the notice is defective.

Undercounted postal service days. If the notice was sent by post, 7 working days must be added for delivery before the notice period starts counting. Working days exclude Saturdays, Sundays and NSW public holidays. Landlords who count 7 calendar days instead of 7 working days produce a vacate date that is too early — and the notice is short-served.

Unlawful service method. Text message, WhatsApp, and leaving a notice under the door are not permitted service methods under section 223. A notice served this way is defective; section 113 allows NCAT to make an order despite a service defect only if it considers that appropriate and is satisfied the tenant suffered no disadvantage or any disadvantage has been overcome.

Renovation notice while a repair order is active. Section 87F(2) of the Act blocks significant-renovation termination notices while an NCAT order under section 65(2) or a Fair Trading rectification order under section 65C is in force against the property.

Defects NCAT May Overlook

Section 113 of the Act allows NCAT to make an order despite a defect in a termination notice or its service if it considers that appropriate and is satisfied the tenant suffered no disadvantage or any disadvantage has been overcome. Examples that might be treated as defects without disadvantage include:

• A minor spelling error in the landlord's name
• The wrong unit number when the correct property was obvious from context
• A formatting irregularity in the notice layout

But the statutory conditions still apply. A wrong vacate date, missing required evidence, or absent Termination Information Statement can invalidate the notice; whether NCAT can make an order despite the defect depends on the section 113 test.

You Cannot Fix a Defective Notice

A landlord cannot unilaterally amend or withdraw a served termination notice. Under section 112, withdrawal requires the consent of all other parties to the tenancy agreement. If the tenant refuses, the landlord must issue a fresh compliant notice rather than rely on the defective one.

The correction protocol:

1. Ask the tenant to consent to withdrawal of the defective notice and keep a record of the response
2. If they consent — issue a fresh notice with full statutory notice periods and correct attachments
3. If they refuse — do not rely on the defective notice; issue a fresh compliant notice with the full statutory notice period

Either way, the timeline restarts. For a 90-day ground, a single notice defect costs a minimum of 3 additional months.

A Pre-Service Checklist

Before serving any termination notice, verify:

• [ ] Correct statutory ground identified and stated in the notice
• [ ] All mandatory evidence for that ground attached
• [ ] Termination Information Statement (current Fair Trading version) attached
• [ ] Vacate date calculated correctly — including postal buffer if serving by mail
• [ ] Vacate date does not fall before the fixed-term expiry (for non-fault grounds)
• [ ] Service method is one of the five permitted under section 223
• [ ] No active repair order against the property (for renovation notices)
• [ ] Notice signed and dated by the landlord or their licensed agent
