Deeds Of Consent Explained: Use Cases For Australian Companies

As your Australian company grows, you’ll likely bring in new people and make big decisions - adding a shareholder, appointing a director, onboarding an investor, or restructuring your group. Moments like these are exciting, but they also raise a practical legal question: how do you make sure every new participant is clearly and legally bound to the rules and agreements you already have in place?

That’s where a deed of consent comes in. It’s a simple, formal way to say “I agree to those terms” - with the added certainty and enforceability that a deed provides.

In this guide, we’ll explain what a deed of consent is, when you should use one, how execution works under Australian law, and how it fits with the rest of your company documents. By the end, you’ll know when a consent is worth the extra formality - and how to put one in place properly so you can move forward with confidence.

What Is A Deed Of Consent?

A deed of consent is a short, formal document where a person or entity confirms they agree to be bound by an existing agreement or set of rules. Unlike a simple contract, a deed doesn’t require an exchange of value (consideration) to be binding, which is why lawyers often use deeds for promises or acknowledgements that need extra certainty.

In a company context, you’ll most often see deeds of consent used when someone new joins an existing framework - for example, a new shareholder agreeing to your Shareholders Agreement or a new director acknowledging your governance rules. In some transactions you’ll also hear the term “deed of accession” used for the same purpose: it’s a deed that lets a new party accede to (join) an existing contract on the same terms as the originals. If you’re weighing up deed vs agreement more broadly, it can help to first understand what a deed is under Australian law.

The goal is simple: get everyone on the same page, in writing, with the right level of formality so there’s no doubt about who is bound by what.

When Do Australian Companies Use Deeds Of Consent?

Any time a new person or entity needs to be bound by an existing document, a deed of consent is worth considering. Common use cases include:

• New shareholders or investors: When you issue shares or transfer them, the incoming holder usually signs a deed of consent to be bound by your existing Shareholders Agreement (including voting rules, pre-emptive rights, and exit processes).
• Appointing a new director or officer: Boards often want incoming directors to acknowledge the rules in the Company Constitution or board policies via a short consent.
• Unit trusts and managed structures: New unitholders commonly sign an accession or consent deed so they’re bound by the trust deed or unitholders agreement on the same terms as existing members.
• Group restructures: When you roll assets into a new entity or set up subsidiaries, consents help ensure each relevant party is bound to existing intercompany agreements, restraints and confidentiality obligations.
• Capital raises and exits: As part of a fundraising or share sale, investors often require consents to confirm warranties, restrictions, side letters or amended terms apply to everyone.

If someone is joining an existing “rulebook” and you want complete certainty they’re bound by it, a deed of consent is usually the cleanest solution.

How Does A Deed Of Consent Work (And How Do You Execute It Properly)?

A deed of consent is typically short - often only a few pages - but it needs to hit the right notes. A well-drafted consent will usually:

• Identify the consenting party (the person or entity joining).
• Clearly reference the document(s) they’re agreeing to (for example, the Shareholders Agreement dated X, the Constitution adopted on Y).
• State that they agree to be bound as if they were an original party, from the effective date.
• Pick up any special obligations that matter for new joiners (confidentiality, restraints, dispute resolution, IP assignment, notices).
• Set out practicals like governing law, effective date, and how notices will be given.

Execution and witnessing

Deeds carry formal execution requirements. For companies, execution can be done under section 127 of the Corporations Act 2001 (Cth) (for example, two directors, or a sole director/secretary) - see this practical guide on signing documents under section 127. Individuals may need a witness depending on the state or territory and the type of deed.

It’s important to separate two concepts: company execution under s 127 and witnessing requirements for individuals. Company execution doesn’t require a witness under s 127. By contrast, an individual’s deed execution may require witnessing in some jurisdictions. If you’re unsure which applies, it’s worth checking the legal requirements for signing documents based on who is signing.

Electronic signing and counterparts

Australian law generally permits electronic execution and signing in counterparts for company documents, with conditions. Your deed of consent can accommodate e-signing and counterparts if the wording is right. Many transactions rely on these mechanics to keep things moving.

Deed Of Consent vs Contract: What’s The Difference?

Both deeds and contracts are binding, but they serve slightly different purposes.

• Consideration (exchange of value): Contracts require consideration to be enforceable, whereas deeds do not. That’s why a consent - which is more of a one-way promise to be bound - is often done by deed.
• Formality and intention: A deed signals a higher level of formality and intention to be bound, which can be useful when adding parties to sensitive arrangements like restraints, confidentiality or investor protections.
• Use cases: Contracts are great for everyday commercial deals. Deeds shine when you need a party to accede to existing terms, give a release, provide a guarantee or make a promise without a direct quid pro quo.

If you already have a long-form agreement in place and simply need a new person to join, a deed of consent (or deed of accession) keeps it efficient - you don’t have to rewrite the original agreement.

What Other Documents Sit Alongside A Deed Of Consent?

A deed of consent is one tool in a broader legal toolkit. The right suite for your business will depend on your structure and plans, but many Australian companies also rely on the following:

• Shareholders Agreement: Sets the ground rules for ownership, decision‑making, transfers, valuation mechanics and exits. You’ll typically have each incoming holder sign a consent to join your Shareholders Agreement.
• Company Constitution: Your internal governance rulebook. New directors or shareholders often acknowledge the Company Constitution in their consent.
• Confidentiality (NDA): When sharing sensitive information with prospective investors, partners or executives, a short Non‑Disclosure Agreement protects your IP and trade secrets.
• Employment and contractor agreements: If you’re hiring, a clear Employment Contract or contractor agreement sets expectations, IP ownership and restraints from day one.
• Privacy Policy: If your business is an APP entity under the Privacy Act 1988 (Cth) (for example, many businesses with annual turnover of $3m+ or handling certain types of sensitive data), you’ll need a compliant Privacy Policy. Even if you’re not legally required, many online businesses still adopt one to build trust and meet platform and customer expectations.
• Deed of Accession: In some deals, the consent instrument is expressly called a Deed of Accession - functionally similar to a deed of consent, tailored to the original agreement’s language.

You won’t need everything at once. But as your company evolves, ensuring each new participant is properly bound - and your core documents are aligned - will save you time and reduce risks.

How To Put A Deed Of Consent In Place (Step-By-Step)

1) Confirm why you need the consent

Start by identifying the existing document(s) the new party must join (for example, Shareholders Agreement dated 1 July 2023). Make a short list so the deed can reference each one clearly.

2) Prepare a concise draft

Your deed should identify the consenting party, reference the document(s), state that they are bound as if an original party, and capture any specific obligations that matter for new joiners (like restraints or confidentiality). Keep it clear and readable - avoid copying large chunks of the original agreement unless they genuinely need to apply separately.

3) Check execution requirements and sign

Decide who is signing and how. For a company, consider executing under s 127 (more on section 127 execution here). For individuals, check if a witness is required in your state or territory. If you plan to use e‑signing, ensure your deed wording supports electronic execution and counterparts.

4) Update your registers and records

Once signed, circulate PDF copies to all parties and update any relevant registers (share register, option register, unitholder records). Store the deed with your company’s core agreements so it’s easy to locate.

5) Keep a clean paper trail

Maintain a simple index of who has signed which document and when. This reduces confusion in future fundraising, due diligence or exit events - and it speeds up legal reviews.

Common Pitfalls (And How To Avoid Them)

• Vague or missing references: A deed that doesn’t clearly identify the documents being joined can create uncertainty. Include title, date and parties of the underlying agreement where possible.
• Forgetting key obligations: If your original agreement expects certain obligations (confidentiality, restraints, IP assignments) to apply to new joiners, make sure your consent picks them up expressly.
• Incorrect execution: Mixing up witnessing requirements with company execution under s 127 is common. Companies can sign without a witness under s 127; individuals may need a witness depending on jurisdiction. When in doubt, check the signing requirements before you circulate the final.
• Relying on a generic template: Templates often miss deal‑specific rules (like pre‑emptive rights or drag‑along clauses). If your consent doesn’t match your original agreement’s mechanics, you can end up with gaps.
• Not aligning with cap table and registers: Your legal documents and your cap table should tell the same story. After each consent is signed, update the registers and any investor records immediately.

FAQs: Quick Answers To Common Questions

Is a deed of consent the same as a deed of accession?

In practice, yes. “Deed of accession” is a common label for a deed that lets a new party accede to an existing agreement on the same terms as the originals. Many businesses use the terms interchangeably. Some transactions prefer the specific wording and mechanics baked into a dedicated Deed of Accession.

Do all new directors need to sign a consent?

It’s good governance to have new directors acknowledge the Constitution and key policies. Whether you do this by board resolution, letter of appointment or deed of consent depends on your preferences and the level of formality you want. A short deed keeps the acknowledgement clear and enforceable.

Do I always need a Privacy Policy when I’m using a deed of consent?

Not necessarily. A Privacy Policy is legally required if you’re an APP entity under the Privacy Act (many businesses with $3m+ annual turnover, or those handling health or certain sensitive data). Plenty of smaller businesses still choose to have a Privacy Policy to build trust and meet platform expectations, but it’s not automatically mandatory for every business.

Can I use a consent to patch in updated terms?

Yes - a consent can be paired with a variation deed to add new parties and update specific terms at the same time. Make sure your drafting clearly distinguishes between the accession and the variation so there’s no confusion.

Should consents cover confidentiality and restraints?

Often, yes. If your original agreement contains confidentiality or restraint provisions that are meant to apply to anyone who joins, the deed of consent should pick those up expressly so they bite on new joiners.

Key Takeaways

• A deed of consent is a simple, formal way to bind new people to your existing company documents without rewriting the whole agreement.
• Typical use cases include new shareholders, directors, unitholders, restructures and capital raises where new parties must join existing terms.
• Execution matters: companies can sign under s 127 without a witness; individuals may need a witness depending on their jurisdiction, and e‑signing is usually possible with the right wording.
• Match your consent to the underlying agreement - clearly reference the document, pick up key obligations, and keep your registers and cap table in sync.
• A deed of consent sits alongside core documents like your Shareholders Agreement, Company Constitution, NDAs and Employment Contracts; use the right mix for your stage and structure.
• Templates can miss critical details; getting tailored drafting or a quick legal check now can prevent disputes or delays later.
