When a dispute flares up, a deadline is missed, or a regulator calls - a simple, fast way to de‑escalate things is to ask for (or offer) a written undertaking.
In plain English, a written undertaking is a formal promise, in writing, that a person or company will do (or stop doing) something by a certain time. It can be a practical, low‑cost tool to resolve issues before they snowball - but only if it’s prepared properly and you understand its legal effect.
In this guide, we’ll explain what a written undertaking is, when your business should use one, what to put in it, and how to make sure it’s actually enforceable in Australia. We’ll also walk through execution and enforcement tips so you can protect your position with confidence.
What Is A Written Undertaking?
A written undertaking is a signed, written promise to take specific actions or refrain from certain conduct. It’s often used to avoid litigation, close out a dispute, or satisfy a compliance concern without a formal court order.
Common examples include promises to stop using another business’ confidential information, to pay an outstanding amount by set dates, or to fix a compliance issue by a deadline.
On its own, an undertaking is simply a promise. Whether it’s legally binding depends on how it’s framed and executed. As a rule of thumb:
- If the undertaking is part of a broader agreement with consideration (each side gives something), it can operate as a contract.
- If it’s executed as a deed, it can be binding even without consideration. Learn more about how deeds work in Australia under What Is A Deed In Australian Law.
- If it’s simply a letter of intent or a “promise to try”, it may not be enforceable and could leave you exposed.
Because the label “undertaking” isn’t magic, the way you draft and sign it matters. If you need teeth, consider making the undertaking a deed or embedding it within a settlement agreement.
When Would A Small Business Use A Written Undertaking?
Undertakings are versatile. You might use one to resolve a dispute quickly, satisfy a third party that things will be put right, or lock in conduct while you perform due diligence. Typical scenarios include:
Stopping IP Or Confidentiality Breaches
If a competitor or ex‑contractor has used your brand or know‑how, an undertaking can require them to stop, destroy copies and confirm in writing. Often this follows a cease and desist letter, and can sit alongside a confidentiality or Non‑Disclosure Agreement to prevent future misuse.
Payment Plans And Commercial Disputes
Where invoices are overdue, you may accept an undertaking to pay in instalments, with default consequences if they miss a date. If the dispute is broader (for example, both sides allege breaches), it’s safer to package the promises within a Deed of Release and Settlement so all issues are finalised.
Employment And Contractor Transitions
Departing staff may give undertakings around returning property, non‑solicitation and confidentiality. If you’re relying on restraint obligations, get advice - you may need a tailored restraint or separate support such as restraint of trade advice to ensure the restrictions are reasonable and enforceable.
Supplier Or Safety Compliance
Suppliers might give undertakings about compliance with standards, timetables or remedial steps after a breach. In regulated contexts (for instance, consumer product safety or advertising claims), an undertaking can be part of your remediation plan to reduce risk under the Australian Consumer Law.
Leases And Property
Commercial landlords and tenants sometimes use undertakings to deal with make‑good obligations, repairs, or to bridge the gap before a formal variation or deed is signed.
Is A Written Undertaking Legally Binding?
It can be - but not always. The enforceability of a written undertaking turns on three things: legal form, certainty, and execution.
1) Legal Form
To be binding as a contract, you generally need offer, acceptance, intention to create legal relations, and consideration (each party gives something). If the other side is only “promising”, you might lack consideration - which is why many businesses use a deed format instead.
Deeds don’t require consideration to be binding, provided they meet formalities. That’s why undertakings are often structured as a deed (for example, a standalone deed poll) or included in a deed of settlement. If you’re weighing deed options, this overview of Deed Polls is a helpful primer.
2) Certainty And Specifics
Courts won’t enforce vague promises. Your undertaking should set out exactly what will be done (or stopped), by whom, and by when. Include specifics about timeframes, deliverables, reporting, and what happens on default.
3) Proper Execution
Make sure it’s signed correctly. For companies, execution can follow section 127 of the Corporations Act (two directors, a director and secretary, or a sole director/sole secretary), or by an authorised signatory. See our guide to signing documents under section 127.
Electronic signatures are widely used - just ensure your process is reliable and the counterparty agrees. Compare options in Wet Ink Signatures vs Electronic Signatures. For deeds, some states impose witnessing or formality requirements - check whether witnesses are needed and who can act, using Witness Signature Rules In Australia.
How Do I Request Or Give A Written Undertaking?
Here’s a practical, step‑by‑step approach to keep things efficient and low‑risk.
Step 1: Define The Outcome You Need
Be clear about the problem and the result you’re seeking. Is it a stop of conduct, a payment schedule, rectification work, a public notice, or a combination? Map the obligations into concrete actions and dates.
Step 2: Choose The Right Instrument
If it’s a simple one‑sided promise (for example, a departing contractor promising to stop using your assets), consider using a deed format so it’s binding without consideration. If both sides are giving releases or making mutual promises, a settlement deed may be better. Our guide to a Deed of Release and Settlement explains how this ties everything off.
Step 3: Draft The Undertaking With Specifics
Set out the obligations clearly, the timeframes, any evidence required (for example, certification that data was deleted), and what happens if there’s a breach. Avoid vague language like “best endeavours” unless you deliberately want flexibility.
Step 4: Include The Right Supporting Clauses
Common additions include confidentiality, costs, default interest, governing law, notices, and a clause acknowledging you’re relying on the undertaking. If the promise relates to confidential information, you may also want a separate or embedded NDA to cover future disclosures.
Step 5: Execute Correctly
Arrange signature in accordance with company signing rules or power of attorney. If it’s a deed, ensure deed formalities are met and any required witnesses sign in the right place. Where possible, align execution with section 127 to simplify enforceability - see section 127 execution for options.
Step 6: Monitor Compliance
Diary key dates, request any agreed reports or certificates, and follow up early if something slips. If the undertaking included staged payments or rectification milestones, automated reminders help avoid misunderstandings.
What Should A Written Undertaking Include?
Every situation is different, but most undertakings include the following building blocks.
- Parties And Capacity: Identify who is giving the promise (individual or company) and confirm authority. If you need extra security, consider a director or parent company support via a Deed of Guarantee and Indemnity.
- Background (Recitals): A short, factual summary of the context. Keep this neutral - it’s not a place to re‑litigate the dispute.
- Undertakings (The Promises): Clear, numbered obligations - what must be done, by whom, and by when. Use precise timeframes and any technical standards or definitions you rely on.
- Evidence Of Compliance: For example, “within 7 days provide written certification that all copies of X were destroyed” or attach a completion report template.
- Default Consequences: Set out interest on late payments, accelerated sums, liquidated damages (if appropriate) or a right to seek urgent orders.
- No Admissions: If you’re resolving a dispute, both sides may wish to say there’s no admission of liability (this is typical inside a settlement deed).
- Confidentiality: Prevents the terms being disclosed (with standard exceptions). For ongoing protection of sensitive information, add a separate Non‑Disclosure Agreement.
- Costs: Who pays legal or enforcement costs if there’s a breach.
- Governing Law And Jurisdiction: Keep it local and practical.
- Execution Block: Tailored for companies or individuals and compliant with deed or contract formalities (including witnesses if required).
If you’re using the undertaking to wrap up an active dispute, it’s often better to use a deed of settlement, which can include mutual releases and “no further claims” provisions alongside the promises.
Undertaking, Contract Or Deed - What’s The Difference?
These terms get mixed up, so here’s a quick way to approach it from a risk perspective.
- Undertaking is the promise itself. It could live in an email, a letter or a formal document. By itself, it may not be enforceable unless it forms part of a binding contract or deed.
- Contract binds parties when there’s offer, acceptance, intention and consideration. A well‑drafted settlement agreement with undertakings inside will usually be a contract. If a party breaches, you have standard contract remedies - damages, termination, and in some cases specific performance. See a practical overview of breach of contract and the usual steps to enforce.
- Deed is a formal instrument that’s binding without consideration (when validly executed). If you want a one‑sided promise to have “teeth”, packaging the undertaking as a deed is often the way to go. Start with the basics in What Is A Deed and, for one‑sided promises, consider how deed polls work.
There are other instruments that sometimes get confused with undertakings, such as waivers and releases. A waiver addresses the risk of claims being brought (for example, customers accepting risk of an activity) and has its own rules - see Understanding Legal Waivers. A release resolves claims (often within a settlement deed). Choose the tool that fits the job.
Execution: Getting The Signing Right
Execution mistakes are a common reason documents fail. Keep these points in mind:
- Capacity And Authority: Confirm the signatory can bind the entity. If a company is signing, align with section 127 or attach evidence of delegated authority.
- Deed Formalities: If you’re using a deed, ensure correct wording (deed style) and any witnessing requirements are met. Refer to witness rules for your state or territory.
- Electronic Signing: Use a reputable e‑signature platform and keep audit trails. Some deeds can be signed electronically depending on the jurisdiction and company status; compare options in wet ink vs electronic signatures.
- Counterparts: Allow signing in counterparts and via email to avoid delays. Keep signed copies organised - you’ll need them if there’s a breach.
Enforcement: What If The Undertaking Is Breached?
Even with the best drafting, breaches happen. The key is to move quickly and proportionately.
- Issue A Breach Notice: Point to the clause breached, the facts, and the remedy required within a short timeframe. Keep it factual and attach evidence where possible.
- Escalate Default Consequences: Apply default interest, accelerate sums, or suspend services as allowed by the document.
- Seek Injunctive Relief (If Urgent): For IP misuse or confidentiality breaches, you may need urgent orders to stop the conduct.
- Negotiate A Variation Or Settlement: If circumstances changed in good faith, it may be sensible to vary timing or convert to a broader settlement. A formal settlement using a Deed of Release and Settlement can reset obligations and finalise disputes.
- Litigate As A Last Resort: If it’s a contract or deed, you can rely on breach of contract remedies, including damages and (in appropriate cases) specific performance. Keep contemporaneous records - compliance reports, correspondence and evidence of loss are critical.
Tip: Build enforcement into the drafting. For example, include liquidated damages for late removal of infringing content, or an indemnity covering costs you incur to enforce the undertaking.
Practical Tips To Make Written Undertakings Work
- Be Specific, Not Aspirational: Replace “will seek to” with “will do X by Date Y”. If you need flexibility, say so explicitly (for example, “subject to the following conditions”).
- Tie In Evidence: Require certification, screenshots, system logs, or third‑party confirmations where appropriate.
- Back‑Up Security: For payment undertakings, consider security such as a guarantee, a charge, or staged delivery. A guarantee and indemnity can provide extra comfort if the counterparty is thinly capitalised.
- Align With Other Documents: If you already have a master services agreement or Business Terms, make sure the undertaking is consistent or clearly overrides where needed.
- Keep “No Admissions” And “Without Prejudice” Straight: Use “without prejudice” for negotiations only; the final undertaking itself should be open (so you can rely on it). Include a “no admissions” clause if reputation or future claims are a concern.
- Close The Loop: Where you’re resolving a live dispute, consider final releases and confidentiality - usually within a settlement deed - rather than relying on a standalone promise alone.
Frequently Asked Questions About Written Undertakings
Do I Need A Lawyer To Draft A Written Undertaking?
You don’t have to - but it’s wise. The whole point of an undertaking is to avoid bigger problems. A short consult can help you choose the right legal instrument (contract vs deed), set clear obligations, and avoid loopholes.
Can An Email Undertaking Be Enforceable?
Sometimes, yes - if the elements of a contract are present and the parties clearly intended to be bound. But relying on informal emails creates risk. If enforceability matters, formalise it as a contract or deed and ensure proper execution.
Is A Waiver The Same As An Undertaking?
No. An undertaking is a promise to act (or not act). A waiver is a person giving up a right. Waivers have their own rules about clarity and fairness - see Understanding Legal Waivers - and are used for different purposes.
Should I Use A Deed Poll For A One‑Sided Undertaking?
Often, yes. If only one party is promising and you need enforceability without consideration, a deed poll can be ideal. Get across the basics in our guide to Deed Polls and make sure you follow deed formalities.
Key Takeaways
- A written undertaking is a formal, written promise - useful to resolve issues quickly and avoid escalation, but only binding if it’s set up properly.
- For a one‑sided promise, consider using a deed so it’s enforceable without consideration; for mutual obligations, a settlement contract or deed is usually better.
- Draft with precision: spell out actions, deadlines, evidence of compliance and default consequences, and make sure the right person signs with proper authority.
- Think ahead to enforcement: include practical monitoring steps, interest or liquidated damages, and consider security such as a guarantee if payment timing is critical.
- If an undertaking is breached, act quickly: issue a notice, escalate contract remedies, and convert to a settlement deed or seek urgent orders if needed.
- Execution matters: use section 127 where possible, follow witness rules for deeds, and use reliable electronic signing where appropriate.
