Notice To Complete: What Australian Businesses Need To Know In Commercial Contracts

Contracts keep your deals moving. But when a counterparty stalls on settlement, delivery or payment, delays can quickly affect cash flow and operations.

That’s where a Notice to Complete can come in. It’s a formal step that, in the right kind of contract, puts the other party on a clear deadline to perform-often as a precursor to termination or other remedies if they still don’t comply.

Notices to Complete are well‑known in property and business sale transactions, and they also show up in some high‑value commercial contracts. The catch: whether you can use one (and what it achieves) depends on the terms of your agreement and the surrounding law. There isn’t a single “standard 14‑day” rule that applies across all contracts.

In this guide, we’ll unpack when a Notice to Complete is used in Australia, how to issue one properly, the risks to watch, and practical steps to keep your deal on track-even if performance is slipping.

What Is A Notice To Complete?

A Notice to Complete is a formal written notice requiring the other party to complete their contractual obligations by a new, specified deadline. It’s most commonly seen in transactions with a defined “completion” or “settlement” event-such as a property settlement, a share sale, or the completion of a business purchase.

Two points are critical:

• It usually works because the contract already allows it. Many sale, lease or development agreements include a clause that lets a party serve a Notice to Complete and makes “time of the essence” after the notice period.
• If the contract is silent, you may still be able to make time essential by giving reasonable written notice-but this depends on the circumstances and the contract’s overall structure. It’s not automatic for every commercial agreement.

Think of a Notice to Complete as a final, formal trigger: it establishes a clear “last chance” date for performance and often unlocks termination and damages rights if the deadline is still missed.

Because the notice must align with the contract and general principles of contract law, it’s worth revisiting the foundations of offer and acceptance, conditions and breach to see how your specific deal fits.

When Is A Notice To Complete Used?

Notices to Complete are most effective where the contract has a defined completion event and the parties expect to settle on a specified date. Common examples include:

• Business or asset sales: The contract sets a settlement date for transferring assets, paying the purchase price and delivering completion deliverables. This may be paired with a Business Sale Agreement that includes a Notice to Complete mechanism.
• Property transactions and leases: In conveyancing and some commercial leases, “time of the essence” is well recognised, and Notices to Complete are a familiar tool. If you’re dealing with lease variations or assignments, a Commercial Lease Review can confirm what your notice rights actually are.
• Complex projects or staged contracts: In some construction, development or technology deals, completion milestones and longstop dates are built in, sometimes with express rights to serve notice and terminate if stages aren’t delivered.

In everyday supply, services or distribution contracts, you won’t always see a Notice to Complete clause. Remedies for delay may be handled differently (e.g. liquidated damages, step‑in rights, suspension or termination for material breach). Check the written agreement first.

Key Conditions To Keep In Mind

• Contractual basis: Your right to serve a Notice to Complete usually comes from the contract. If there’s no clause, seek advice before giving a “completion” deadline-an invalid notice can backfire.
• Reasonable time: There is no universal 14‑day rule. The timeframe must be reasonable in the context-what is “reasonable” for settling a business sale may differ from handing over a data room or delivering specialised equipment.
• Readiness: The party serving the notice typically needs to be “ready, willing and able” to complete themselves (e.g. funds available, documents prepared). If you’re not ready, your notice may be ineffective.
• Good faith and fairness: Australian contract law doesn’t impose a universal duty of good faith in all contracts. Some agreements include an express good faith clause; some courts imply one depending on the context. Either way, unreasonable or opportunistic use of a notice can be challenged.

How Do You Issue A Notice To Complete Properly?

Getting the process right matters. A defective notice may be unenforceable-and can even put you in breach if you then try to terminate based on it.

1) Re‑read The Notice And Completion Clauses

Start with the written agreement. Look for clauses about:

• Completion: What must each party do at completion? Is the date fixed or adjustable? Are there preconditions?
• Notice mechanics: How must notices be given (email, post, courier)? To whom? When are they deemed received (e.g. not on weekends/holidays)?
• Remedies for delay: Does the contract allow a Notice to Complete? Does it say that time becomes “of the essence” after notice?

If the document needs to be varied to reset dates or extend time, follow a compliant variation process. For many agreements, that means a simple deed or amendment letter-see this overview on amending contracts the right way.

2) Confirm You’re Ready To Complete

Before sending a Notice to Complete, line up what you need for completion:

• Funds for settlement or payments.
• Execution‑ready documents, board approvals or authorities.
• Third‑party consents or releases (e.g. landlord or key supplier consents).

If execution is by an Australian company, consider whether signing under s 127 is available for clean, self‑proving execution-see signing documents under section 127 of the Corporations Act.

3) Draft The Notice Clearly

Your notice should:

• Identify the agreement and the relevant completion obligation(s) and clause numbers.
• State precisely what the counterparty must do to complete (e.g. pay the balance, deliver specified deliverables, execute attached documents).
• Specify a reasonable deadline (date and time) by which completion must occur.
• State the consequences of non‑compliance (e.g. right to terminate, keep a deposit, or claim damages) as permitted by the contract.

Keep the tone professional and objective. Avoid making threats or admissions that could be used later in a dispute.

4) Serve The Notice Exactly As The Contract Requires

Follow the notice clause to the letter:

• Use the method required (for example, registered post to a street address or email to a named contact).
• Send it to the correct address or email listed in the contract (update details if the parties agreed any changes).
• Allow for deemed delivery rules-if a notice is “deemed received” on business days only, factor that in when setting your deadline.

If the agreement requires formalities for notices or execution, align with those requirements. Where a formal signing process is mandated, you can also cross‑check the general legal requirements for signing documents in Australia.

5) Keep Complete Records

Retain copies of:

• The final signed contract and any variations.
• The notice (signed) and any exhibits or schedules attached to it.
• Proof of service (postage receipts, courier tracking, email headers).
• Any responses from the other side.

A clean paper trail is essential if you later need to justify termination or claim losses.

What Happens If The Deadline Is Missed?

If the other party still fails to complete by the notice deadline, your contract will usually set out the consequences. Common outcomes include:

• Termination rights: You may be entitled to end the contract and walk away from further obligations. Where a clean exit is needed, parties often document this formally using a Deed of Termination.
• Deposits and interest: For sale transactions, the defaulting party may forfeit a deposit or pay interest for late completion-if the contract provides for it.
• Damages: You may claim losses that flow from the breach (for example, extra financing costs, missed opportunities, or professional fees incurred due to the delay). The contract may cap or exclude some types of loss.

Courts can sometimes grant relief against forfeiture of deposits or strict timing, especially where the consequences are disproportionate. That’s another reason to ensure your timeframe is reasonable and your notice complies with the agreement.

If you plan to terminate, check that no conditions precedent remain unsatisfied due to your own acts or omissions, and confirm you are not in breach yourself. Wrongful termination can itself be a repudiation of the contract.

Can You Extend The Deadline Instead?

Yes-if both parties still want the deal, it’s common to extend the completion date, waive minor preconditions, or re‑sequence closing steps. Record any changes in writing, following the contract’s variation clause or using a short deed. For sale deals with multiple moving parts, confirm the revised “closing deliverables” list is complete and internally consistent.

Alternatives And Practical Tips To Keep Deals Moving

Not every delay needs a Notice to Complete. Consider these practical options first or alongside a notice:

Escalate Early And Solve For The Blocker

Pick up the phone. Ask what’s preventing completion and propose a precise fix-an escrow arrangement, a temporary holdback, or an alternative deliverable. Many issues aren’t legal; they’re logistical.

Use A Short Standstill Or Milestone Plan

Agree a short, written plan with dates for each outstanding item and who does what by when. This can sit alongside the contract and-if you need it later-support a reasonable Notice to Complete timeframe.

Vary The Agreement Properly

If the timeline is no longer realistic, put a variation in place rather than letting deadlines lapse. A compliant variation avoids arguments about waiver or estoppel and reduces the risk of accidental breach. Here’s a practical refresher on contract variations and when a deed is preferable.

Use Targeted Completion Mechanics In Your Contracts

For future deals, build in completion discipline from the start:

• Clear deliverables: List exactly what must happen at completion (payments, executed documents, transfers, releases).
• Notice mechanics: Spell out whether a Notice to Complete is available, how time becomes of the essence, and the effect of non‑compliance.
• Deemed timings: Include business day definitions and cut‑off times so there’s no ambiguity on when notice periods end.
• Security and holdbacks: Use deposits, escrow, or retention sums to incentivise timely completion without rushing an unready counterparty.

Have The Right Transaction Documents

Well‑drafted transaction and ancillary documents make completion smoother. In sale deals, that typically includes a tailored Business Sale Agreement with clear conditions, completion deliverables and a workable notice regime. If the parties later need to transfer obligations to another entity, a Deed of Assignment can manage that change properly.

For leases and property‑adjacent arrangements, an early lease review can identify timing traps, notice quirks and conditions precedent you’ll need to satisfy before completion.

Execution And Closing Pack Discipline

Map out who signs what, and how. If you’re relying on company execution for speed or certainty, consider whether s 127 execution (two directors, or a sole director/secretary) is available, as outlined in the section 127 guide. Keep a closing checklist and tick items off as you receive them.

Avoid Common Missteps

• Assuming a “standard” period: Don’t default to 14 days without thinking-choose a timeframe that’s defensible for your specific transaction.
• Serving the notice incorrectly: If the contract says courier to a street address, don’t email it and hope for the best. Follow the notice clause.
• Overlooking your own readiness: If you can’t complete on the nominated date, your notice may be ineffective.
• Relying on generic law: Contract law is primarily common law and (for goods) state Sale of Goods legislation. Company law (like the Corporations Act) regulates companies and signing mechanics-it isn’t a “general contract law” fallback.

Key Takeaways

• A Notice to Complete is a formal tool that sets a final, reasonable deadline to perform-most effective where the contract has a defined completion or settlement event.
• There’s no one‑size‑fits‑all “14‑day” rule; the availability, content and effect of a notice depend on your specific contract and context.
• Before serving a notice, check the contract, confirm you’re ready to complete, draft precisely, and serve the notice exactly as the notice clause requires.
• If the deadline is still missed, your agreement may allow termination, deposit forfeiture or damages-often documented cleanly with a Deed of Termination.
• Many delays can be solved with a short variation, milestone plan or targeted completion mechanics built into a tailored sale agreement or lease.
• For company execution and closing packs, align with the rules for signing under section 127 and keep a clear audit trail.
