Everyone needs to play by the rules, including companies. But how do companies manage the nature of their business, the rights and duties of members and directors, and the way they interact with each other?
This is where a company constitution becomes invaluable. A company constitution is a legally binding document that sets out how your company operates, as well as establishing the rights and obligations of key players such as members, directors, and the company secretary.
A constitution can be adopted at the time of company registration, after your company is established, or you may choose not to adopt one at all. For constitutions adopted when you set up a new company, each member must agree in writing to the terms – a practice that remains a cornerstone of sound corporate governance in 2025.
If you decide not to adopt a company constitution, your company will instead be governed by the “replaceable rules” outlined in the Corporations Act. These broad, default rules provide a basic framework for managing your company in the absence of a bespoke constitution.
If you choose to adopt a constitution after registering your company, you must do so by passing a special resolution. This official process requires that at least 75% of voting members agree to the new constitution – ensuring any change reflects a strong consensus. It’s essential to follow any specific notice and procedural requirements set out in your existing constitution or the replaceable rules.
Where Did Company Constitutions Come From?
Historically, corporate governance was managed through two separate documents: the Memorandum of Association, which dealt with a company’s external relations, and the Articles of Association, which governed internal operations. Over time, these have been replaced by the modern company constitution – a single, comprehensive document that streamlines the governance process and is better suited to today’s dynamic business environment.
Do I Need A Company Constitution?
While adopting a company constitution is not strictly a legal requirement, it is highly recommended. When registering your company, ASIC requires you to choose between drafting your own constitution or relying on the default replaceable rules provided by the Corporations Act – or even a combination of both. For more insight into these decisions, our guide on business structure options might prove useful.
Although the replaceable rules offer a no-cost baseline for company governance, a well-crafted constitution provides greater protection and clarity. It can help prevent disputes over matters such as the issuance of new shares, key company decisions, or the authority of individuals to bind the company. With additional provisions developed by experienced lawyers, a tailored constitution is especially valuable in 2025 when regulatory standards and business practices continue to evolve.
For many companies, particularly those with more complex operations, a customised constitution is an asset that complements other legal safeguards – much like pairing your governance framework with professional contract drafting services to ensure comprehensive protection across all areas of business.
How Do I Get A Constitution?
You can engage a lawyer to draft a bespoke constitution tailored to your company’s unique needs. Alternatively, many incorporation platforms – including those provided by services such as EasyCompanies – include a standard constitution as part of the set-up process. If you’re unsure which option suits you best, our company set-up guide provides clear, step-by-step advice.
It is also crucial to stay informed about emerging legal developments and ASIC updates. With new regulatory guidelines introduced in 2025, periodically reviewing your company’s governing documents is a smart strategy.

Can I Change A Company Constitution?
Yes, you can amend or even dispense with your company’s constitution by passing a special resolution. These changes must comply with the notice and procedural requirements specified in your current constitution or the replaceable rules, and must be approved by at least 75% of the voters. For further guidance on revising legal documents, our resource on contract review and redrafting can help you understand best practices.
When making amendments, ensure you follow any specific notice requirements laid out in your existing documentation. Additionally, if you are a public company, remember that you must notify ASIC of any constitution changes – a process that has been refined with new efficiencies in 2025.
Conclusion
Operating a company requires clear, well-defined rules to facilitate effective decision-making and conflict resolution.
