What Does Section 127 Of The Corporations Act Say?

If you run a company in Australia, you’ll regularly need to sign contracts, deeds and other documents. Section 127 of the Corporations Act 2001 (Cth) is the key rule that tells you how a company can “execute” (legally sign) documents so they’re binding, and so other people can safely rely on them.

The good news is that Section 127 gives you clear options for signing, including electronic signing. The flip side is that a small mistake (like using the wrong signatories) can make a document unenforceable or delay a deal.

In this guide, we’ll break down what Section 127 actually says in plain English, when to use it, and practical tips to help you sign documents the right way from day one.

Why Section 127 Matters For Australian Companies

Section 127 is designed to make execution simple and reliable. When you follow it, your document benefits from a legal “shortcut”: third parties (like customers, suppliers or lenders) can assume it’s been properly signed without digging into your internal records.

That means faster deals, less back-and-forth, and fewer risks of someone questioning your authority to sign later on.

Just as importantly, executing under Section 127 often avoids extra formalities (like witnessing for deeds) and reduces the need to produce board minutes or proof of authority every time.

What Does Section 127 Actually Allow?

Section 127 sets out the ways a company can validly execute a document. There are two broad methods: with a common seal (less common these days) and without a seal (the most common approach).

Executing Without a Common Seal

Most companies don’t use a common seal anymore. Without a seal, a company can execute a document if it’s signed by:

• Two directors of the company; or
• One director and one company secretary; or
• For proprietary companies with a sole director, that sole director (with or without a company secretary, following recent legislative reforms).

If you’re a proprietary company with a single director and no company secretary, modern reforms have made it easier to sign under Section 127 in your own name. If your situation is unusual (for example, your company constitution imposes extra requirements), it’s worth checking what your Company Constitution says.

Executing With a Common Seal (Optional)

If you still use a common seal, the seal needs to be affixed to the document and witnessed by the appropriate officers (typically two directors, or a director and company secretary). The seal route is optional; most companies now rely on the signature approach above.

Deeds, Agreements, Notices And More

Section 127 can be used to execute most types of documents, including deeds and agreements. When you properly execute a deed under Section 127, you usually don’t need a witness (unlike individuals signing deeds in some states). If in doubt, confirm whether your document is intended to be a Deed and ensure the signature block and wording reflect that.

Why This Matters To Counterparties (Section 129 Assumptions)

One of the biggest benefits of using Section 127 is how it interacts with the statutory assumptions in Section 129 of the Corporations Act. In short, if a document appears to be executed in accordance with Section 127, the other party can generally assume it has been duly executed and is binding on the company.

This reduces the need for the other side to ask for internal approvals or board minutes every time. It’s a practical and legal “safe harbour” that keeps deals moving.

Can You Use Electronic Signatures And Counterparts?

Yes. Reforms introduced in 2021-2022 made electronic execution the default-friendly option for companies. You can generally sign documents electronically under Section 127, including deeds, as long as the method satisfies three common-sense requirements:

• It identifies the person signing.
• It indicates their intention to sign.
• It is reliable for the purpose (or is proven to be as a matter of fact).

That means reputable e‑signature platforms are suitable in most cases. For deeper background on the shift from pen-and-paper to digital, see electronic signatures in Australia.

Split Execution And Counterparts

Section 127 also accommodates “split execution”. If two company officers need to sign, they don’t have to sign the same physical page at the same time. Each officer can sign a separate, identical counterpart, and together those counterparts will form one executed document. For more on how this works in practice, read about counterparts.

When To Stick With Wet Ink

Even though electronic signing is broadly accepted, some banks, registries or overseas counterparties may still insist on wet ink or specific formalities (especially for certain property or finance documents). If your counterparty specifies a method, follow their requirements to avoid delays.

Section 126 vs Section 127: Which Should You Use?

It’s easy to mix up Sections 126 and 127 because both deal with signing. Think of them this way:

• Section 127: a “company execution rule”. It’s about how the company itself executes a document through its officers. Use this when you want the comfort of Section 129 assumptions and the cleanest path for third parties to rely on the signature block.
• Section 126: a “power to contract” provision. It lets a company make, vary or discharge a contract through an individual acting with the company’s authority (for example, a director, employee or agent). It’s broader and more flexible but may not always give third parties the same razor‑clear assumptions as a Section 127 execution block.

Both are valid pathways, and sometimes Section 126 is the only practical option (for example, quick acceptance of a purchase order by an authorised manager). If you want a refresher on the contracting power pathway, see Section 126.

Which Path Gives More Comfort To The Other Side?

When you sign under Section 127, third parties can usually rely on the Section 129 assumptions without extra due diligence. That’s why banks, investors and major suppliers often request a Section 127 execution block.

By contrast, if someone signs under Section 126, the other side might ask for evidence of their authority (for example, a board minute, Authority to Act, or a delegations policy) before they’re comfortable.

Practical Tips To Execute Documents Safely Under Section 127

Here are practical steps we recommend so your documents are valid, efficient and easy for others to rely on.

1) Use The Right Signing Combination

Match the officer titles to your company’s register. If you’re using “two directors”, make sure both are currently recorded as directors. If you’re using “director and company secretary”, ensure the secretary is appointed. For sole director companies, confirm whether a secretary is appointed and use the correct form of signature block.

2) Choose A Clear Execution Block

Use a signature block that states “Executed by ACN in accordance with Section 127 of the Corporations Act 2001 (Cth)”. Then set out the appropriate officer titles (Director/Director, or Director/Company Secretary, or Sole Director and, if applicable, Sole Company Secretary). Clarity here saves back-and-forth later.

3) Embrace E‑Signatures (But Keep An Audit Trail)

Electronic signing is efficient and widely accepted. Make sure the platform captures the signer’s identity, time stamps, and a completion certificate. If a counterparty still requests wet ink, consider signing in both formats to keep the timeline moving.

4) Deeds: Label Them Properly And Keep The Formalities

If the document is a deed, say so in the title or opening clause (for example, “Deed of Confidentiality”). Ensure any special deed formalities required by the document are followed. When executed under Section 127, deeds generally don’t require a witness for the company’s signatures, but check the drafting carefully and make sure your execution block aligns with being a Deed.

5) Counterparts And Split Execution Are Fine

Don’t hold up your deal because signatories are in different places. It’s standard to allow counterparts and split execution. Make sure the document says counterparts are permitted and keep all executed parts together in your file.

6) Keep Your Registers And Constitution Up To Date

Out-of-date officer details are a common source of execution hiccups. Keep ASIC records current and review your Company Constitution so your execution method isn’t contradicted by bespoke rules (for example, a legacy clause mandating use of a common seal).

7) Evidence Of Authority (When Not Using Section 127)

If you’re executing under Section 126 (for example, by an authorised manager) or accepting terms by email, keep records that prove authority (board minutes, delegated authority matrix, or a director’s resolution). A short director’s resolution can avoid future disputes about who was allowed to bind the company.

8) Align The Execution Block With The Parties

Double check you’re signing on behalf of the correct entity. If your group includes subsidiaries, the correct company must execute. If a trustee company is signing as trustee of a trust, the signature block should say so.

9) Watch For Overseas Or Registry Requirements

Some registries, banks or overseas counterparties still require wet ink, notarisation or apostille. If your deal involves property, finance or cross‑border elements, confirm any extra steps early so execution doesn’t become the bottleneck.

10) Common Pitfalls To Avoid

• Using the wrong titles (for example, listing someone as “Company Secretary” who was never appointed).
• Leaving out the ACN or the Section 127 reference in the signature block when the other party expects it.
• Mixing up entities (signing in the parent company’s name for a subsidiary’s contract).
• Assuming “anyone in the business can sign” without authority (that’s a Section 126 issue-document the authority if you’re not using a Section 127 block).

FAQs We Hear From Business Owners

Does Section 127 require witnesses? No-if a company executes under Section 127, a witness is not generally required (including for deeds). Individuals signing in their personal capacity are a different story, and some states require witnesses for individuals signing deeds.

Can a sole director sign alone? Typically, yes. Proprietary companies with a sole director can generally execute under Section 127 with that director’s signature (with or without a company secretary, depending on how the company is structured). If you’re unsure how your company is set up, check your ASIC records and constitution.

Do both officers need to sign the same page? No. Split execution is permitted. Each officer can sign a counterpart or separate page.

Can we just accept a proposal by email instead of formal execution? Often yes, but that’s more of a Section 126 pathway. If you go this route, make sure the person accepting has authority. For higher‑value contracts or where the counterparty insists, using a Section 127 execution block is safer and cleaner.

What if we need to sign fast but the second officer is unavailable? Consider whether a Section 126 authority or delegated authority can be used for that particular transaction, or arrange for electronic signing so officers can sign from any location. For sensitive or high‑value deals, push for a proper Section 127 execution as soon as practicable.

Key Takeaways

• Section 127 sets out how an Australian company can validly execute documents-most commonly by two directors, a director and secretary, or a sole director for proprietary companies.
• Executing under Section 127 gives counterparties confidence through statutory assumptions (Section 129), often speeding up deals and reducing requests for extra proof of authority.
• Electronic execution and split execution are generally permitted, including for deeds, provided your method identifies the signer and indicates their intention to sign.
• Use Section 127 when you want the “gold standard” execution block; use Section 126 when a duly authorised individual is contracting on the company’s behalf and a formal execution block isn’t practical.
• Keep your officer appointments current, align the signature block to the correct entity, and make sure your constitution doesn’t impose unexpected execution rules.
• For extra comfort in complex deals, align your execution approach with the counterparty’s requirements and keep an audit trail (especially when using e‑signatures or counterparts).
