When you’re documenting a deal in Australia, one of the first questions you’ll face is whether to use a deed or an agreement (also called a contract). These documents both create legally binding obligations - but they don’t work in exactly the same way.
Choosing the right format can affect whether your promise is enforceable, how you need to sign it, how long you can bring a claim, and even whether you need to provide consideration (value) at all.
In this guide, we’ll unpack the practical difference between deeds and agreements, when to use each, and what to watch out for when signing so your document actually works as intended.
What Is A Deed In Australian Law?
A deed is a formal legal instrument that records a person’s or company’s serious promise, traditionally “signed, sealed and delivered.” Today, deeds are commonly used to make a promise enforceable without needing consideration (for example, a gratuitous promise to release someone from liability). Deeds carry extra formality and specific signing requirements compared to standard contracts.
If you want a deep dive, you can start with this overview of what a deed is under Australian law.
Key features of a deed include:
- They can be binding even without consideration.
- They often use formal wording (e.g. “executed as a deed”).
- They may require witnessing (for individuals) and a clear intention to be bound immediately on delivery.
- They usually attract a longer limitation period for claims (commonly 12 years, and in some states up to 15 years).
What Is An Agreement (Contract)?
An agreement (contract) is a legally binding bargain. To be enforceable, it typically requires an offer, acceptance, intention to create legal relations, certainty of terms and consideration (something of value from each side, such as payment or services).
Agreements are very flexible and are used for the vast majority of day-to-day business arrangements, from supplier terms to customer contracts. While they’re generally simpler to execute than deeds, they do rely on consideration and they typically have a shorter limitation period (often six years, depending on the state or territory).
Deeds Vs Agreements: The Key Differences
1) Consideration
Consideration is what each party gives or promises (e.g. money for services). Agreements need consideration to be enforceable. Deeds do not - which is why they’re used for certain one-way promises (for example, a release given at the end of a dispute where one party isn’t paying anything).
2) Formality And Wording
Agreements can be simple and informal (though clarity is always wise). Deeds must show a clear intention to be executed as a deed, often using phrases like “This document is executed as a deed” and including a delivery provision. That extra formality helps courts distinguish deeds from ordinary contracts.
3) Execution And Witnessing
With agreements, standard signature blocks usually suffice (subject to any internal authority requirements). Deeds have stricter execution rules, especially for individuals who may require witnessing. Companies follow specific Corporations Act options for signing deeds and may have different formalities than individuals.
If you’re unsure whether your document has been signed properly, it’s worth checking the legal requirements for signing documents to avoid unenforceability.
4) Limitation Periods
Limitation periods set how long you have to bring a claim. For agreements, it’s commonly six years (state and territory laws vary). For deeds, the period is longer - typically 12 years, and in some jurisdictions 15. This can be crucial for long-term obligations (e.g. guarantees or restrictive covenants).
5) Delivery And When It Binds
A deed takes effect on “delivery,” which legally means the party intends to be bound immediately (or at a specified future time). Agreements typically bind on execution (signing) once all elements of contract formation are present.
6) Variation And Termination
Agreements can generally be varied by another agreement with consideration. Deeds can be varied by a further deed. In practice, if you start with a deed, keep using deed format for changes unless you receive advice that a contract variation will suffice.
7) Use Cases
Agreements are ideal for everyday two-way bargains (supply of goods or services, employment, software licensing). Deeds are preferred where you need enforceability without consideration, a longer claim period, or added formality - e.g. releases, settlements and certain guarantees.
When Should You Use A Deed Instead Of An Agreement?
You don’t always need a deed. But there are recurring scenarios where a deed is the safer or more practical choice because of the no-consideration rule, the longer limitation period or the need for formality.
Common business examples include:
- Deed of Release/Settlement: To settle a dispute and release claims, especially where one party isn’t paying consideration or where you want a longer period to enforce obligations. See how a Deed of Release and Settlement typically works.
- Guarantees And Indemnities: Third-party guarantees (e.g. a director guaranteeing a company’s obligations) are often done by deed due to formality and enforceability.
- Confidentiality Deeds: If there’s no clear consideration flowing both ways (e.g. one-sided disclosures), a deed can help ensure obligations stick.
- Intellectual Property Assignments: Where IP is assigned for nominal or no consideration (such as founder IP assigned into a new company). A Deed of Assignment is commonly used in this context.
- Gratuitous Promises: Any situation where you want an enforceable promise but nothing of value is being exchanged in return.
By contrast, an agreement is generally suitable for two-way commercial arrangements where consideration is clear - for example, your customer contract, a supplier agreement or a standard services arrangement.
How To Execute A Deed Or Agreement Correctly
Even a beautifully drafted document can fall over if it’s executed incorrectly. The right approach depends on who is signing (individuals vs companies) and the format (wet ink, electronic or hybrid).
Individuals And Partnerships
Individuals typically sign a deed in the presence of an independent adult witness who also signs and prints their full name and address. Some states require witnessing for a deed to be valid; others are more flexible, but witnessing remains best practice for individuals. For agreements, witnessing isn’t usually required, but it can help with evidencing execution if ownership or identity is later disputed.
Companies (Section 127 Corporations Act)
Companies have specific signing methods for both agreements and deeds. The Corporations Act allows companies to execute documents under section 127, which provides evidentiary benefits and reduces the need to prove authority later. The rules vary depending on whether you have two directors, a sole director and company secretary, or another configuration.
If you’re executing in the company’s name, it’s worth following the recognised methods in section 127 to avoid arguments about authority and validity.
Electronic Signatures And Remote Signing
Electronic execution is now widely accepted in Australia for many documents, including company execution of deeds, provided certain conditions are met (e.g. the method identifies the signer and shows intention to be bound). That said, state and territory rules still vary for individuals and witnessing.
If you’re planning to sign electronically, check the latest guidance on wet ink versus electronic signatures to make sure your method is compliant and appropriate for the document type.
Witnessing And Common Mistakes
Witnessing requirements can be strict for deeds signed by individuals. Using the wrong witness (e.g. an interested party) or missing witness details is a common error. It’s also important that each party signs the correct execution block (individual vs company) and that the document’s wording clearly states that it’s a deed (if that’s your intention).
Not sure who can witness? These witness signature rules cover common scenarios so you avoid invalid execution.
Practical Drafting Tips And Risk Management
Getting the structure right is half the job. These drafting tips can help you avoid pitfalls and keep your document enforceable in practice.
- Be Clear On Format: Decide early whether you need a deed (e.g. to avoid consideration issues) or an agreement. Avoid mixing language (e.g. calling it a “deed” but using contract-style execution blocks).
- Use Clear “Deed” Wording: If you choose a deed, use wording like “executed as a deed” and include a delivery clause so there’s no ambiguity about intention.
- Match Execution To The Party: Individuals, companies and trustees have different execution requirements. Ensure the right signing blocks, witness lines and capacity statements (e.g. “as trustee for…”) are used.
- Check Authority: If someone signs for another party, confirm they have authority (e.g. board approval, power of attorney or an internal authority to act process). This is especially important for group companies and franchise structures.
- Include Counterparts And E-Signing Clauses: If signing in different places or times, counterparts and electronic execution clauses reduce risk and logistics pain.
- Set Governing Law And Jurisdiction: Choose the Australian state or territory whose laws will apply, and keep it consistent with where parties are based if possible.
- Record Consideration (If Any): Even in a deed, consider reciting nominal consideration if there will be any exchange - it can assist with interpretation.
- Keep A Clean Version Control Trail: Ensure everyone signs the same final version and store it securely. This sounds simple, but it’s a common source of disputes.
For settlement documents, releases and assignments, these details matter. If you need a starting point or a sense-check, our resources on a Deed of Release and a Deed of Assignment outline the typical structure and clauses you’ll see in practice.
Which Option Is “Better” - Deed Or Agreement?
Neither is universally better. It depends on your commercial goal and the legal characteristics you need.
- Choose an agreement for most two-way commercial deals with clear consideration and a standard risk profile.
- Choose a deed when you need enforceability without consideration, a longer enforcement window, or greater formality (e.g. releases, guarantees, one-way obligations).
If you’re ever on the fence, consider the signing logistics as well. For example, if multiple individuals are involved and arranging witnesses will be difficult, check whether an agreement will achieve the same outcome - or whether a company can sign under section 127 to streamline execution. Where electronic signing is planned, confirm the document type and parties align with the rules for e-signatures and witnessing in your state, and review the signing requirements before sending the document out.
Key Takeaways
- Agreements need consideration to be enforceable; deeds do not. That’s the main legal difference business owners rely on.
- Deeds have stricter formality and execution requirements and usually attract a longer limitation period (often 12 years, sometimes 15).
- Use a deed for releases, settlements, guarantees and one-way obligations; use an agreement for most two-way commercial bargains.
- Execution matters: individuals may require witnesses for deeds, and companies should consider signing under section 127 to reduce risk.
- Electronic signing is widely accepted, but check the rules for your party type and document category and review the basics on wet ink vs electronic signatures before you proceed.
- Clear wording, correct execution blocks, witnessing (where needed) and version control are simple steps that prevent disputes later.
