What Are Legal Undertakings? A Clear Guide For Businesses In Australia

Running a business in Australia comes with lots of promises - to customers, suppliers, investors, regulators and sometimes the courts. Some of those promises are casual and good‑faith. Others are formal, binding, and carry serious consequences if you don’t follow through.

Those formal promises are often called legal undertakings. If you’ve heard the term but aren’t sure exactly what it means, how it works, or when you might need one, you’re in the right place.

In this guide, we’ll explain what a legal undertaking is, how it differs from a contract or a deed, when undertakings arise in business, what makes them enforceable in Australia, and the practical steps to manage them confidently. We’ll also point out the key documents where undertakings usually sit, and the traps to avoid so you stay compliant and protect your business.

What Is A Legal Undertaking?

A legal undertaking is a clear, formal promise to do something (or not to do something) that is intended to be legally binding.

In practice, undertakings appear in a few common ways:

• Contractual undertakings: promises inside a contract - for example, to deliver goods by a date, pay fees on time, or keep information confidential.
• Court undertakings: voluntary promises given to the court (and recorded on the court record or in orders) - for example, promising to preserve assets or refrain from a certain action until the next hearing. These aren’t “court‑ordered”; they are promises to the court that can be enforced as contempt if breached.
• Regulatory undertakings: formal promises given to a regulator (for example, the ACCC) - often called “enforceable undertakings” - where a business commits to specific actions to address potential breaches of the Australian Consumer Law (ACL) and prevent recurrence.

What matters is the intention and effect. An undertaking goes beyond “we’ll try” - it’s a commitment the other side (or the court/regulator) can rely on. If you don’t comply, there can be real legal and financial consequences.

Undertakings vs Contracts vs Deeds: What’s The Difference?

Undertakings, contracts and deeds are related - but not the same. Understanding the differences helps you decide the right legal tool for each situation.

• Contract: a legally binding agreement between two or more parties. Under basic contract law, you generally need an offer, acceptance, an intention to be legally bound, and consideration (value flowing both ways).
• Undertaking: a specific promise that may sit inside a contract, be given directly to a court, or be accepted by a regulator. If it’s outside a contract, it usually needs to be supported by consideration or executed as a deed to be enforceable between private parties.
• Deed: a special type of legal instrument used to formalise promises without the need for consideration (for example, when only one party is making a commitment). Because deeds bypass the consideration requirement, they’re commonly used for standalone undertakings between businesses. If you’re weighing this option, it’s worth understanding what is a deed and how to execute one properly.

Two practical points to keep you safe:

• If an undertaking is part of a broader contract (with consideration), it is usually enforceable as a contractual term.
• If an undertaking stands alone, make sure it’s backed by consideration or executed as a deed - otherwise you risk creating a promise that looks serious but isn’t legally enforceable between private parties.

If you do use a deed, it must be executed correctly to be valid. Double‑check the legal requirements for signing documents in Australia before you sign.

When Is An Undertaking Enforceable (And Who Can Bind Your Company)?

For an undertaking to bite legally in Australia, you’re looking for a few essentials.

• Clear and specific terms: the promise must be definite - not just a statement of intent.
• Proper form: inside a contract (with consideration) or executed as a deed if it’s a standalone promise. Court and regulatory undertakings follow their own processes once accepted and recorded.
• Authority to bind: the person giving the undertaking on behalf of a business must have authority to bind the company or entity.
• Intention to be legally bound: the context and wording should make it clear this is a binding commitment, not a courtesy or aspiration.

Authority is a common pressure point. Under the Corporations Act, a company can be bound by agents acting with actual or apparent authority. It helps to understand section 126 (who can make, vary or discharge contracts on behalf of a company) and to use recognised execution methods, such as signing under section 127 for deeds and agreements.

Because undertakings can be serious, make sure only authorised team members provide them. If there’s any doubt about authority or wording, get advice before you sign or speak on behalf of the company.

What Happens If An Undertaking Is Breached?

• Contractual undertakings: the other party may seek damages, specific performance (a court order to do the thing promised), or other remedies under the contract.
• Court undertakings: breaching a promise given to the court can amount to contempt of court, which may lead to fines and, in serious cases, imprisonment.
• Regulatory undertakings: the regulator may escalate with enforcement action or seek orders to compel compliance and impose penalties.

Bottom line: don’t give an undertaking unless you’re confident you can comply - and have the authority to give it.

Where Undertakings Show Up In Business (With Examples & Key Documents)

Undertakings pop up in day‑to‑day operations more than most businesses realise. Here are common scenarios, the kind of promises typically made, and the documents that capture them.

• Supplier and customer relationships: timing of delivery, quality standards, payment terms, and exclusivity. These sit in service agreements or terms and conditions. If you sell goods or services to consumers, you also need to align your promises with the Australian Consumer Law (for example, refund rights and product claims) and consider a clear warranties against defects statement where relevant.
• Confidentiality and collaborations: promises to protect trade secrets and limit use of information. These live in a Non‑Disclosure Agreement (NDA) or confidentiality clause within a broader agreement.
• Employment and contractors: undertakings to follow policies, protect IP, and meet post‑employment restrictions. Use a tailored Employment Contract or contractor agreement with clear, reasonable obligations.
• Governance and founder arrangements: undertakings between owners about decision‑making, restrictions on share transfers, funding, and dispute resolution. These sit in a Shareholders Agreement (or Unitholders Agreement for unit trusts).
• Settlements and dispute resolution: promises to do (or stop doing) certain things to resolve a dispute are captured in a Deed of Settlement, which is commonly used because a deed doesn’t require consideration and is designed to be final and enforceable.
• Regulatory and court settings: commitments to change advertising, improve compliance programs, or preserve assets pending proceedings. These are formalised through enforceable undertakings to the regulator or undertakings to the court and should be drafted with care.

If a promise is important to your deal or your risk position, make sure it is written in the right document, expressed clearly, and signed correctly. Vague promises are hard to enforce and easy to misinterpret.

A Practical Process To Manage Undertakings

Here’s a simple, repeatable approach you can apply across your business.

1) Spot When You’re Making (Or Receiving) A Binding Promise

Flag situations where someone is committing to a concrete outcome or restraint - not just best efforts. Typical triggers are proposals, heads of agreement, policies, court or regulator correspondence, and contract negotiations.

2) Decide The Right Legal Vehicle

• If the undertaking forms part of a broader deal with mutual obligations, include it as a contractual term.
• If it’s a standalone promise, consider using a deed and confirm execution formalities are met.
• If it’s to a court or regulator, make sure the process and wording satisfy their expectations.

3) Draft With Precision

• Define exactly what must (or must not) be done.
• Set any timeframes, conditions and standards.
• State who is responsible, and any dependencies.
• Include consequences or remedies if it’s not done.

If the promise resolves a dispute or needs to stand on its own, consider capturing it in a deed; for complex settlements, a purpose‑built Deed of Settlement is common practice.

4) Check Authority And Execution

Confirm the person giving the undertaking has authority to bind the entity and that signatures follow the correct method (for companies, think section 126 authority and section 127 execution where applicable).

5) Keep Records And Track Compliance

Store the signed document and key correspondence. Create reminders for deadlines and assign internal owners. Undertakings should be visible in your compliance calendar, not lost in email threads.

6) Escalate Early If Something Changes

If you think you’ll miss a deadline or a term needs to change, communicate early and seek advice before you breach. Variations should be documented properly - ideally with the same formality as the original undertaking.

Documents That Often Contain Undertakings

These are the everyday documents where undertakings typically live. Make sure they’re tailored to your business and executed correctly.

• Customer Terms / Service Agreement: the core promises you make to clients or customers (scope, delivery, fees, service levels, limits of liability).
• Non‑Disclosure Agreement (NDA): formal promises to keep information confidential and limit use, often mutual between parties. A standalone NDA is ideal before sharing sensitive information.
• Employment Contract: obligations around confidentiality, IP, policies, and (where appropriate) post‑employment restraints.
• Shareholders Agreement: undertakings between owners about governance, funding, exits, and dispute processes, helping prevent deadlocks.
• Deed of Settlement / Release: used to finalise disputes, with promises to take (or stop) certain actions and to release claims going forward.
• Regulatory compliance documents: enforceable undertakings to regulators (for example, around advertising, refunds, or compliance programs) and internal policies that embed those commitments.

If you’re formalising important promises, consider using a deed where there’s no consideration, and ensure your document is signed using the correct method. When in doubt, get a quick review before you proceed.

Key Takeaways

• A legal undertaking is a clear promise to do - or not do - something, and it’s meant to be relied on.
• Inside a contract (with consideration) an undertaking is usually enforceable as a term; for standalone promises between private parties, use a deed or ensure consideration exists.
• Undertakings given to courts are voluntary promises recorded on the court record; breaching them can amount to contempt. Regulatory undertakings are formal promises accepted by a regulator and can be enforced.
• Only authorised people should give undertakings on behalf of your business. Know how authority works (section 126) and use correct execution methods (such as section 127 for companies).
• Be precise in your drafting, keep strong records, and track deadlines. If circumstances change, escalate early and vary the promise properly.
• Common places you’ll see undertakings include NDAs, Employment Contracts, Shareholders Agreements and settlement deeds - make sure yours are tailored and signed correctly.
