Section 127 of the Corporations Act: Executing Documents

26 Apr 2026

Proper execution of documents is fundamental to the validity and enforceability of commercial agreements and corporate actions. For Australian companies, Section 127 of the Corporations Act 2001 (Cth) provides a critical framework for this process, offering clear methods for companies to sign documents and ensuring certainty for third parties.

Understanding Section 127 of the Corporations Act 2001 (Cth)

Section 127 of the Corporations Act 2001 (Cth) sets out the primary ways in which a company may execute a document without needing to use a common seal. This provision streamlines corporate transactions by providing statutory methods that, when followed, assure counterparties that the document has been properly signed by the company.

Methods of Execution Under Section 127(1)

A company may execute a document without a common seal if it is signed by:

  • Two directors of the company; or
  • A director and a company secretary of the company.

Execution for Sole Director/Secretary Proprietary Companies

For proprietary companies that have a sole director and that director is also the sole company secretary, Section 127(1) provides a simplified method: the document can be executed by that sole director alone. This acknowledges the distinct structure of many small to medium-sized Australian businesses.

Execution Using a Common Seal

While less common in modern practice, Section 127(2) permits a company to execute a document using its common seal if the affixing of the seal is witnessed by:

  • Two directors of the company; or
  • A director and a company secretary of the company.

For a proprietary company with a sole director who is also the sole company secretary, the affixing of the common seal must be witnessed by that sole director.

Purpose of Section 127

The primary purpose of Section 127 is to provide certainty and efficiency in corporate dealings. It establishes a clear, statutorily endorsed mechanism for document execution, reducing the need for lengthy and complex internal authorisation checks by third parties. This legislative framework helps to facilitate commerce by instilling confidence in the validity of corporate signatures.

The Power of Statutory Assumptions: Sections 128 and 129

The true strength of Section 127 lies in its interaction with Sections 128 and 129 of the Corporations Act 2001 (Cth). These sections establish critical statutory assumptions designed to protect persons dealing with companies.

What are Statutory Assumptions?

Sections 128 and 129 create legal presumptions that a person dealing with a company is entitled to make about the apparent authority of the company's officers and the proper execution of its documents. These assumptions operate in favour of an outsider dealing with a company, preventing the company from denying the validity of an action merely because it failed to comply with its own internal rules.

How Section 129(5) Relates to Section 127

Crucially, Section 129(5) provides that a person may assume that a document has been duly executed by the company if the document appears to have been signed in accordance with Section 127(1) (without a seal) or Section 127(2) (with a seal). This means:

  • If a document appears to be signed by two directors, or by a director and a company secretary, or by a sole director/company secretary of a proprietary company, a third party can assume it has been duly executed.
  • The third party does not need to verify the signatories' actual authority, check the company's constitution, or inspect board resolutions.

These statutory assumptions are powerful because they significantly reduce the due diligence burden on counterparties, making transactions faster and more secure. The only exception to these assumptions is if the person dealing with the company knew or suspected that the assumption was incorrect. The Australian Securities and Investments Commission (ASIC) oversees compliance with the Corporations Act and provides guidance on corporate governance matters.

Electronic Execution and Split Execution

The landscape of document execution saw significant modernisation with amendments to the Corporations Act. Initially introduced as temporary measures during the COVID-19 pandemic, the ability for companies to execute documents electronically has now been made permanent by the Corporations Amendment (Meetings and Documents) Act 2022.

Permanent Electronic Execution

A company can now execute documents electronically if the method of signing:

  • Identifies the person signing; and
  • Indicates the person's intention in respect of the information recorded in the document.

This means that digital signatures, electronic signing platforms, and similar technologies are valid methods for companies to execute documents under Section 127. This permanent reform reflects contemporary business practices and enhances efficiency.

Split Execution

The amendments also explicitly permit "split execution," sometimes referred to as "counterpart execution" in an electronic context. This allows the signatories required under Section 127(1) or (2) (e.g., two directors or a director and company secretary) to sign:

  • A single electronic document; or
  • Separate copies of the electronic document (e.g., each signatory signing their own PDF copy, which are then collated).

This flexibility is particularly useful in situations where signatories are geographically dispersed, further streamlining corporate transactions. For more detailed information on corporate compliance, the ASIC website is a valuable resource.

When Section 127 May Not Be Sufficient or Applicable

While Section 127 is broadly applicable, there are specific situations where additional formalities or different procedures may be required. Understanding these exceptions is crucial to ensuring document validity.

Deeds

Deeds generally require specific formalities beyond a simple signature to be validly executed. While Section 127 outlines methods for a company to execute documents, the common law requirements for deeds (such as being expressed to be a deed and sealing/attestation) still largely apply. Some Australian states and territories have relaxed sealing requirements for deeds, but the intention to create a deed must be clear. Legal advice should always be sought when executing deeds, particularly regarding specific state-based requirements.

Powers of Attorney

When a company grants a power of attorney to an individual, the company executes the power of attorney document in accordance with Section 127. However, when the attorney then acts under that power of attorney, it is the attorney (the individual) who signs documents on behalf of the company, not the company itself directly through its directors or secretary. The attorney must sign in a manner that clearly indicates they are signing as attorney for the company (e.g., "Jane Doe as attorney for [Company Name] under Power of Attorney dated [Date]").

Documents for Foreign Jurisdictions

When an Australian company executes a document intended to have legal effect in a foreign jurisdiction, Section 127 may not be recognised as sufficient proof of execution. Foreign counterparties, legal systems, or registries often require additional certifications. These may include:

  • Notarisation: A public notary independently verifying the identity of the signatories and witnessing their signatures.
  • Apostille or Legalisation: For countries that are parties to the Hague Apostille Convention, an apostille issued by the Department of Foreign Affairs and Trade (DFAT) certifies the authenticity of public documents (including notarised company documents). For non-Hague Convention countries, "legalisation" through consular channels may be necessary.

Such requirements are often critical for registering interests overseas, overseas court proceedings, or international commercial transactions. Neglecting these can lead to documents being rejected abroad.

Documents Executed by Agents or Attorneys (Other Than Under Section 127)

As noted for powers of attorney, a company can authorise an agent (who is not a director or company secretary signing under Section 127) to sign documents on its behalf. This authority must be properly granted, typically via a board resolution. In such cases, the counterparty cannot rely on the Section 129(5) assumption that the document has been duly executed by the company merely because it was signed by an agent. Instead, the counterparty would need to satisfy themselves that the agent had actual authority. The statutory assumptions usually protect against defects in internal management, not against a complete lack of authority for an unauthorised signatory.

Constitutional Requirements Exceeding Section 127

While Section 127 provides a statutory default, a company's constitution might theoretically impose stricter execution requirements. However, the protection offered by Sections 128 and 129 means that a third party, acting in good faith and without knowledge to the contrary, can generally rely on Section 127 execution methods, even if the company's constitution required more. Nonetheless, it is prudent for companies themselves to ensure internal compliance with their own constitutional documents.

Specific Legislative Requirements

Certain types of documents or transactions may be governed by other specific legislation that imposes its own execution or witnessing requirements, overriding or supplementing Section 127. Examples might include particular financial instruments, some property transfers, or highly regulated industry agreements. Always check for specific legislative provisions applicable to the transaction at hand.
