How deeds work in Australia, execution, delivery and when you need one

A deed is the most formal legal instrument in Australian law, and it exists to do one thing an ordinary contract cannot. It can bind someone to a promise without any payment or value changing hands. A release of claims, an indemnity, a guarantee, a one-way confidentiality undertaking. These are the moments a standard contract is the wrong tool, because a contract needs consideration, a bargain, and a one-sided promise has no bargain in it.

The trade-off for that extra power is formality. A deed only bites if it is written, clearly expressed to be a deed, executed by the right people in the right way, and delivered. Miss a step and the document can be unenforceable, which usually comes to light at exactly the worst time, when someone needs to rely on it. This guide walks through how the deed mechanism actually works: what makes a document a deed, who has to sign and how, when it takes effect, the longer limitation periods that come with a deed, when your business genuinely needs one, and the failure points that trip businesses up.

What makes a document a deed

At common law a deed was a written instrument that had to be sealed and delivered. Sealing has been substantially relaxed across Australia, and the emphasis today is on four things: the document must be in writing, it must clearly show an intention to be a deed, it must be executed in the way the law requires for the person signing, and it must be delivered (with some exceptions we come to below).

Intention matters. A document is a deed only if it says so. For companies, s 127 of the Corporations Act 2001 (Cth) states the rule directly: a company may execute a document as a deed if the document is expressed to be executed as a deed and is executed in the ways the section sets out. In practice that means the document should carry a title like "Deed of Settlement", language such as "executed as a deed" in the execution block, and a complete statement of the parties and operative terms. A deed that is described only as an agreement, or that uses contract language throughout, can be challenged later.

One historical rule has largely fallen away. A physical seal is no longer needed in most situations, and the current legislation makes the point explicitly: under s 127(3A) of the Corporations Act, a company deed may be executed without paper, parchment or vellum at all, and in New South Wales s 38A of the Conveyancing Act 1919 (NSW) confirms a deed may be created in electronic form and electronically signed and attested.

The consideration gap: what a deed can do that a contract cannot

An ordinary contract is only enforceable if each side gives something of value, what lawyers call consideration. A promise to pay, a promise to deliver goods, a forbearance from suing. If there is no exchange, the promise is generally not binding, however solemnly it was made.

A deed removes that requirement. A deed is enforceable because of the formality of its creation, not because of any bargain. That makes it the natural instrument for the one-sided promises businesses rely on every day: a party releasing all claims against another, a company indemnifying a director, a lender taking a guarantee, an outgoing founder promising not to disparage the business. In each case one side gives a promise and the other side gives nothing immediately identifiable in return, so a contract would leave the promise unenforceable.

A deed is also worth considering even where consideration exists. Some parties choose a deed for maximum formality, for the longer limitation period described below, or simply because the counterparty, a bank or a regulator expects one.

How companies execute a deed

When a company signs a deed, the execution rules come from the Corporations Act, and they are precise. Under s 127(1), a company can execute a document without a common seal if it is signed by:

Two directors: the most common route for larger companies.
A director and a company secretary: the standard alternative.
A sole director: but only for a proprietary company, and only if that director is also the sole company secretary, or the company has no company secretary at all.

A company that has a common seal can instead execute by having the seal fixed to the document, witnessed by two directors or a director and a company secretary under s 127(2), and since 2022 the witnessing of the seal can be done by observing it electronically rather than being physically present.

Three details matter for deeds specifically. First, under s 127(3) the document must be expressed to be executed as a deed. Second, under s 127(3A) a company executing under s 127(1) does not need the execution witnessed at all, and the document can be signed in electronic form, which is why deeds can now be completed on e-signing platforms. Third, signing can be done electronically under s 110A, which accepts any method of signing that identifies the person and indicates their intention, provided the method is as reliable as appropriate in the circumstances.

There is a practical payoff for following s 127. A counterparty dealing with a company can rely on the assumptions in s 129(5) of the Act, meaning they do not have to chase evidence of who had authority to sign. That is one of the main reasons businesses prefer a s 127 execution block over a company signing through an agent under s 126.

One caveat: s 127 sets a floor, not a ceiling. It does not limit other ways a company may execute documents, and a company's constitution can impose its own requirements. Before a company signs a deed, it is worth checking the constitution as well as the Act.

How individuals execute a deed

When an individual signs a deed, the signature must generally be witnessed, and the witness must not be a party to the deed. In New South Wales, s 38(1) of the Conveyancing Act 1919 requires every deed to be signed and attested by at least one witness not being a party to the deed. Other states and territories have equivalent attestation rules, so the practical checklist is the same across the country:

Independent witness: someone who is not a party to the deed and has no interest in it.
Present at signing: the witness should see the signature being made, unless a remote witnessing regime applies in the relevant state or territory, and those rules differ, so check the local position.
Completed details: the witness should sign and record their name and address on the deed, so the attestation can be verified later if the deed is ever challenged.
Electronic form: in New South Wales, s 38A confirms a deed can be electronically signed and attested, so an e-signing platform can be used where the counterparty accepts it.

An individual who signs a deed for a company does not need a witness at all if the company is executing under s 127, because s 127(3A) removes the witnessing requirement for that route. The constitution should still be checked, because it can add requirements of its own.

Delivery: when the deed takes effect

At common law a deed takes effect on delivery, and delivery does not have to be a physical handing over. It can be any act or statement showing a clear intention to be bound, such as sending the signed deed by email or instructing that it be released. This is where a small drafting choice removes a large argument: a clause stating the deed is "delivered on execution" makes the timing of effect plain on the face of the document.

For companies the law has simplified the point. Under s 127(3B) of the Corporations Act 2001 (Cth), delivery is not necessary if a company executes a document as a deed in accordance with s 127(1) or (2). The deed takes effect according to its terms rather than on any separate delivery step.

Conditional delivery is still possible where the parties want a deed to take effect only when something else happens, for example a settlement deed that binds on payment of the first instalment. Where that is intended, the condition should be written into the deed or into a clear escrow arrangement, because otherwise a court will ask whether the deed was simply delivered unconditionally.

The longer limitation period

One of the most practical differences between a deed and a contract is time. In most states and territories an action on an ordinary contract must be brought within six years. An action on a deed runs longer:

Twelve years: in most states and territories, including New South Wales, where s 16 of the Limitation Act 1969 (NSW) sets the period for an action founded on a deed at twelve years from the date the cause of action accrues.
Fifteen years: in Victoria, under s 5(3) of the Limitation of Actions Act 1958 (Vic), which applies to actions upon a bond or other specialty.
Fifteen years: in South Australia, under s 34 of the Limitation of Actions Act 1936 (SA), which covers actions of covenant or debt upon any bond or other specialty.

The longer window cuts both ways. If your business is the one owed money or performance under a deed, you have more time to enforce. If your business is the one giving the release or indemnity, you are on the hook for longer, which is one more reason the scope of what you are giving away needs to be drafted carefully. The exact period always depends on the state or territory whose law applies, so the governing law clause in the deed matters as well.

When your business actually needs a deed

Not every agreement needs the formality of a deed, but several recurring situations are genuinely better served by one:

Novation versus assignment: An assignment transfers rights only. Obligations stay with the original party unless the contract is novated, which substitutes a new party and shifts both rights and obligations across, usually with the other party's consent. A deed of novation is the standard way to document a party change after a business sale or restructure, and the rights-only/rights-and-obligations distinction is the single most common source of confusion.
Settlements and clean breaks: Ending a dispute, an employment relationship or a partnership usually involves mutual releases and promises not to pursue claims. A deed of settlement gives each side finality, because the releases bind without needing to identify consideration for each promise.
Waivers, releases and indemnities: Any one-way promise to release claims, waive rights or indemnify against loss is a classic deed situation, from a waiver signed before a risky event to an indemnity given in a share sale.
Director access and indemnity: A deed of access and indemnity gives directors ongoing access to company records and indemnity protection that continues after they leave the board, sitting alongside the constitution and board policies.
IP confirmations: When contractors create intellectual property for your business, a deed confirming that copyright and other IP is assigned to you removes doubt about ownership, particularly where the work was done before a formal agreement existed.
Terminations and variations: Formally ending a commercial relationship, or varying its key terms, is often done by deed, especially where a release is involved or the parties want the longer limitation period.

The governing principle is to match the legal effect you need with the right level of formality. A routine supply agreement does not need a deed. A release that is meant to end all claims between two parties probably does.

How deeds fail in practice

Deeds fall over on technicalities more often than on the merits of the deal. The failures businesses should watch for are these:

Contract language in a deed document: If the document reads like an agreement, refers to consideration, and the execution block says "signed" rather than "executed as a deed", a court may treat it as a contract or hold it invalid as a deed. The document must say it is a deed and be structured as one.
Wrong company execution: A company that fails to sign in accordance with s 127, or in the way its constitution requires, leaves the deed open to challenge. Getting the signatories right is a two-minute check that prevents a long dispute.
Missing or invalid witness details: For individuals, an unattested signature, or a witness who is a party to the deed, can be fatal. The witness must be independent and their details recorded.
Assuming electronic signatures are always accepted: The law permits electronic execution in many situations, but counterparties, banks and land registries may still insist on wet-ink originals for particular transactions. Confirm expectations before the signing date, not after.
No delivery clause: While delivery can be inferred, a statement that the deed is delivered on execution removes doubt about when it took effect, which is exactly the point parties fight over.
Vague releases: A release should say what claims are covered: past, present and future, known and unknown, and against which related parties. The broader the release, the clearer it needs to be.
Novation and assignment mix-ups: If the transaction is meant to move obligations as well as rights, an assignment document will not do it. Use a novation, and make sure the consenting parties all sign.
Missing governing law: A deed without a governing law clause leaves the limitation period and the execution requirements uncertain, which matters even more for a deed than for a contract because the formalities differ by state.
Capacity and authority: Confirm the exact legal entity names and ACNs or ABNs, and who has authority to sign. A trustee signing a deed should sign "as trustee for" the trust, and the trust deed should be checked for any signing requirements.

Where a lawyer helps

Most of the value a lawyer adds to a deed comes before signature. A lawyer can check that the document is expressed as a deed, that the execution block matches the signatories (two directors, director and secretary, sole director, or an individual with a valid witness), that the constitution does not add requirements, and that any trustee or corporate capacity issues are handled correctly. Where a deed is being signed across state lines, or where a counterparty insists on particular execution formalities, advice on the local witnessing and electronic signing rules is worthwhile.

The other area where legal input pays is scope. Releases and indemnities are the clauses that come back to bite years later, and a lawyer can make sure the document says what the parties actually intend it to cover. A review before execution is quick and inexpensive compared with a dispute over whether a deed was validly executed or what it released.

The signing table is where deeds are decided

Every advantage of a deed, the binding one-way promise, the longer limitation period, the finality of a release, depends on the document having been created as a deed in the first place. If execution is defective, those advantages disappear, and the parties are left arguing about what the document was, instead of performing what it said. That is why the execution block and the delivery clause deserve the same care as the commercial terms. A short review by a lawyer before signature, covering the signatories, the witnessing, the delivery language and the scope of any release, is a small cost to pay for a document that is supposed to end disputes rather than start them.
