What Is the Difference Between an Agreement and a Deed? What Australian Businesses Need to Know

If you’re building a business in Australia, you’ll likely come across both agreements and deeds. They’re two common ways to formalise promises and deals - but they aren’t interchangeable. Choosing the right document affects whether your arrangement is enforceable, how you need to sign it, and how long you’ll have to bring a claim if things go wrong.

In this guide, we’ll break down the key differences in plain English, explain when each option makes sense, and walk through the execution rules that trip people up. You’ll leave with practical pointers you can apply straight away - and the confidence to choose the right document for your situation.

Agreements vs Deeds: The Basics

An agreement (often called a contract) is a legally enforceable bargain. In Australian contract law, most agreements require four elements: offer, acceptance, consideration (something of value), and an intention to create legal relations. If you want to refresh the building blocks, see offer and acceptance.

Agreements are used for everyday commercial relationships - supplying goods or services, hiring staff, licensing software, or leasing equipment. They can be in writing, verbal, or even implied by conduct. That said, written contracts are safer because they record the terms clearly and reduce the scope for disputes. If you’re wondering how far a handshake or phone call goes, our guide on verbal agreements answers common questions.

A deed is different. A deed is a formal written instrument used to make or confirm a promise, and it does not require consideration to be binding. In practice, this makes deeds useful for “one-sided” commitments (for example, a guarantee) or where you want a higher level of formality and certainty - such as a settlement that closes off future claims. A deed must be executed with specific formalities and must make clear on its face that it’s a deed (for example, “executed as a deed” in the signature block).

You’ll also see related concepts such as a deed poll (a deed made by one party only). If you’re exploring those formats, it can help to understand how deed polls work and when they’re used.

Key Legal Differences That Matter in Australia

While both documents can be enforceable, the differences below often drive which one you choose.

• Consideration: An agreement generally needs consideration - each side provides something of value (money, goods, services, a promise). A deed does not. This is why deeds suit one-way promises, releases, guarantees and some assignments.
• Formality and wording: A deed must be in writing and clearly expressed as a deed (typically via a heading and execution clause that say “deed”). Agreements don’t require this level of formality, though a clear written record is strongly recommended.
• Execution rules: Deeds have stricter execution requirements than most agreements. Individuals commonly need a witness (check your state or territory’s rules). Companies can execute deeds under the Corporations Act using section 127, which does not require a witness when signed by the prescribed officers. We cover this below in more detail.
• Limitation periods: The “window” to commence a claim for breach is often longer for deeds than for agreements. In many jurisdictions, simple contract claims are generally 6 years, while deed claims are 12 years. Some states differ - for example, Victoria and South Australia have a 15‑year period for deeds. Always check the law for the governing jurisdiction stated in your document.
• Use cases and signalling: Because deeds don’t require consideration and involve additional formalities, they’re commonly chosen for settlements, releases, guarantees, indemnities and certain transfers. The format signals a serious, final commitment.

It’s not accurate to say deeds are “better” or always “stronger” than agreements - they serve different purposes. The right choice depends on what you’re trying to achieve, how the obligations flow, and your appetite for risk.

When Should You Use an Agreement or a Deed?

Situations Suited to an Agreement

• Supplying goods or services to customers on set terms (including online terms for a website or platform).
• Software licences, SaaS terms and reseller arrangements where value flows both ways.
• Employment and contractor arrangements (where consideration is clear and ongoing).
• Joint venture or partnership arrangements, typically with mutual rights and obligations.
• Leases, hire and distribution agreements in normal trading relationships.

In these scenarios, both sides give value, obligations are ongoing, and a well-drafted agreement will usually be the right fit.

Situations Suited to a Deed

• Settlements and final releases, where parties want clear closure on past or potential claims. A Deed of Release and Settlement is the standard format.
• Guarantees and indemnities, where a guarantor or indemnifier makes a one‑way commitment.
• Assignments without consideration, such as transferring IP or contractual rights using a Deed of Assignment.
• Non‑disclosure in a one‑way context (for example, pre‑investment or pre‑sale confidentiality) - although an NDA can also be structured as an agreement where obligations are mutual.
• Confirming a past act or promise that lacked consideration (deeds can “perfect” a promise even where nothing new is exchanged).

If you’re unsure which format suits your situation, think about whether consideration is present, whether you need a longer limitation period, and whether you want the additional formality that comes with a deed. Getting tailored legal input at this stage can save headaches later.

Executing Agreements and Deeds Correctly

Even a perfectly drafted document can fail if it’s not executed properly. Here’s what to watch.

Executing an Agreement

• Authorised signatories: Have each party sign via an authorised representative. For companies, signing under section 127 of the Corporations Act 2001 (Cth) is a safe way to establish due execution.
• Electronic signing: Electronic signatures are widely accepted for commercial agreements. Your execution clause can also allow counterpart signing if needed; see execution in counterparts.
• Clarity and completeness: Make sure the signing blocks clearly identify the signatories and their capacity (for example, director, sole director and sole company secretary, trustee).

Executing a Deed

• Make it a deed on the face of the document: Use clear wording such as “executed as a deed” and include an appropriate delivery clause if required by the governing law.
• Individuals often require a witness: For individuals, a witness is commonly required (and in some states, specific witnessing rules apply). The witness should not be a party to the deed.
• Companies can use section 127: A company can execute a deed without a witness by signing in accordance with section 127 (for example, two directors; or a director and company secretary; or a sole director and sole company secretary for single‑director companies). No witness is generally required under section 127.
• Electronic execution: The Corporations Act recognises electronic execution for companies, and many jurisdictions accept electronic deeds. Always check if the governing law in your deed permits e‑execution and whether any additional steps (such as “delivery” wording) are needed. For context on signatures generally, see wet ink vs electronic signatures.
• Capacity and authority: Ensure the person signing has authority to bind the company or trust. In some cases, section 126 (agency) execution may be appropriate, but use it with care given the extra proof required.

When execution matters are handled correctly, you reduce the risk of challenges about who signed, in what capacity, and whether the deed or agreement is actually enforceable.

How the Choice Plays Out in Real Deals

The differences aren’t just technical - they have practical impacts in common scenarios.

• Settlement at the end of a dispute: If you’ve negotiated a resolution, you’ll usually want finality and a comprehensive release. A deed makes sense here because it can bind parties without fresh consideration and provides a longer period to bring a claim if the release terms are breached.
• Gifting or one‑way promises: If you’re transferring IP or shares without payment, or offering a personal guarantee to support a finance arrangement, a deed ensures the obligation is enforceable even without consideration.
• Ongoing trading relationships: For day‑to‑day supply, distribution, licensing or employment, an agreement is typically the right fit because obligations are mutual and continuous.
• Long tail risk: Where there’s a concern that a breach might only become apparent many years later (for example, hidden liabilities covered by a warranty), parties sometimes choose a deed to take advantage of the longer limitation period in the governing jurisdiction.

There isn’t a single “correct” answer for all deals. The better approach is to match the document to the legal and commercial outcomes you want - including how enforceability, limitation periods and formality affect your risk profile.

Common Mistakes to Avoid

• Calling it a deed without deed formalities: A title alone isn’t enough. If the document doesn’t say it’s a deed and isn’t executed as a deed, a court may treat it as an agreement - which can be a problem if there’s no consideration.
• Missing witnesses for individuals: If a person signs a deed, you’ll typically need an independent witness (subject to local rules). Don’t have a party’s representative act as the witness.
• Assuming a company deed needs a witness: When a company executes under section 127, a witness is not generally required - even for deeds.
• Using the wrong format for one‑sided promises: If there’s no consideration, an agreement may not bind the promisor. A deed avoids that issue.
• Overlooking limitation periods: If you need a longer claim period, use a deed and choose a governing jurisdiction that meets your needs (noting, for example, 12 years in many states and 15 years in Victoria and South Australia).
• Relying on emails alone: Certain email exchanges can create binding contracts, but they often leave gaps. If certainty matters, formalise your terms. If you’re curious about the risks, see whether an email can be legally binding.

A little planning up front - choosing the right format, getting the execution right, and documenting the key terms - goes a long way to reducing disputes.

What Legal Documents Might Your Business Need?

Whether you choose an agreement or a deed, the document should be tailored to your deal. Common documents for Australian businesses include:

• Customer or Service Agreement: Sets out scope, pricing, payment, IP, liability and termination for your core product or service.
• Non‑Disclosure Agreement (NDA): Protects confidential information you share with partners, investors or suppliers; this can be structured as an agreement or a deed depending on whether it’s mutual or one‑way.
• Deed of Release and Settlement: Used to resolve disputes or end relationships with finality, usually via a deed.
• Deed of Assignment: Transfers rights (for example, IP or contract rights) - typically a deed of assignment is used, especially if consideration is nominal or absent.
• Shareholders Agreement: Governs decision‑making, share transfers and dispute resolution between founders or investors (usually an agreement rather than a deed). If you’re setting up a company with co‑founders, a Shareholders Agreement is a smart move.
• Employment Contract: Confirms duties, pay, confidentiality and IP ownership for staff; a standard Employment Contract is an agreement.
• Privacy Policy: Explains how your business collects and handles personal information; a Privacy Policy is essential if you collect customer data.

You won’t necessarily need all of these at once. Start with the documents that map to your most important relationships and risks, then build from there.

Key Takeaways

• An agreement generally needs consideration to be enforceable; a deed does not, which is why deeds suit one‑way promises, releases and certain assignments.
• Deeds require clear deed wording and stricter execution steps. Individuals typically need a witness; companies can execute deeds under section 127 without a witness.
• Limitation periods are usually longer for deeds (often 12 years, and 15 years in some states like Victoria and South Australia) than for agreements (often 6 years).
• Use an agreement for ongoing, mutual commercial relationships; choose a deed where you want finality, a one‑way obligation, or a longer claim period.
• Execution mistakes are common - ensure the right signatories, deed wording, witnessing (if required) and, for companies, consider section 127 to establish due execution.
• Match the document to the outcome you want, and put the right supporting contracts in place (for example, NDA, Deed of Release, Deed of Assignment, Shareholders Agreement and Employment Contracts).
