In short
A company constitution is the document (or, absent one, the replaceable rules in the Corporations Act 2001 (Cth)) that governs a company's internal management — director appointment and powers, meeting procedures, share issue and transfer, and the process for winding up. Most small companies run on replaceable rules by default; a bespoke constitution becomes worthwhile once the company has more than one shareholder, external investment, or governance needs the standard rules don't address.
Replaceable rules versus a bespoke constitution
Under section 141 of the Corporations Act, a company without its own constitution is governed by the replaceable rules set out in the Act — a serviceable default for a simple single-director, single-shareholder company, but generally inadequate once the company has multiple shareholders, wants specific pre-emptive rights on share transfer, needs to restrict share issues, or wants governance provisions the Act's defaults don't cover at all (such as a chairperson's casting vote, alternate director appointment mechanics, or specific quorum requirements for particular decisions). Replaceable rules can also be displaced piecemeal — some provisions adopted, others excluded — which in practice creates confusion about which version of a rule actually applies, and we generally recommend a company either run entirely on replaceable rules or adopt a complete bespoke constitution rather than a partial hybrid.
A bespoke constitution is also usually required (rather than optional) for a proprietary company that wants to restrict the transfer of shares beyond what the replaceable rules provide, for a company converting to a public company, or for a company that wants a single class of shares with different rights attached — none of which the replaceable rules accommodate on their own.
Director powers, appointment and removal
The constitution sets out how directors are appointed and removed, whether the board can appoint additional directors between annual general meetings (and any cap on total director numbers), and what majority is needed for board decisions. For companies with a small or founder-heavy board, we often build in a specific chair's casting vote provision and clarify whether directors can participate in meetings by phone or video, since the replaceable rules' default position on these procedural points is not always clear enough to avoid an argument during a genuine board dispute.
Share issue, transfer and pre-emptive rights
Where the company has, or expects to have, more than one shareholder, the constitution should address whether the board has unrestricted power to issue new shares or whether shareholder approval is required above a threshold, and whether transfers require board approval or are subject to pre-emptive rights in favour of existing shareholders. We coordinate this closely with any shareholders agreement the company has (or is adopting) — the constitution and the shareholders agreement need to say consistent things about share transfer, or a share transfer executed strictly in accordance with the constitution could still breach the shareholders agreement, creating a contractual claim even where the transfer itself is valid.
Different share classes and rights
Companies raising capital from investors, or wanting to give founders different voting or dividend rights from other shareholders, need the constitution to create and define those share classes expressly — ordinary shares, preference shares with a liquidation preference or fixed dividend rate, or non-voting shares for an employee incentive pool. We draft the rights attached to each class with enough precision that a future share issue or capital raise doesn't require reopening the constitution to clarify ambiguous rights.
Meetings, notices and winding up
The constitution fixes quorum and notice requirements for general and board meetings, whether members can pass resolutions without a meeting (circular resolutions), and how notices are validly given (which increasingly means addressing electronic notice under the Corporations Act's technology-neutral provisions). We also address what happens to any surplus assets on a members' voluntary winding up, which for companies limited by guarantee or with a specific mission (such as an incorporated association-adjacent structure) can be an important and sometimes legally required provision.
What the fixed fee covers
- Assessment of whether replaceable rules or a bespoke constitution suit your company
- Full drafting of director appointment, removal and board procedure clauses
- Share issue, transfer and pre-emptive rights provisions coordinated with any shareholders agreement
- Multiple share class drafting where the company has or plans different classes
- Meeting, notice and winding-up provisions
Mistakes we see
- Running on replaceable rules after taking on a second shareholder or outside investment
- Adopting a partial mix of replaceable rules and constitutional provisions with no clarity on which applies
- Constitution and shareholders agreement giving inconsistent answers on share transfer
- Creating a new share class without defining its rights precisely enough to survive a future dispute
- Copying a constitution template from another company without checking it fits your governance needs
Who this is for
- Companies taking on a second shareholder or outside investor
- Companies wanting to restrict share transfer or issue beyond the replaceable rules
- Businesses creating a share class structure for investors or an employee incentive pool
- Companies converting from proprietary to public, or adopting governance beyond the default rules
Frequently asked questions
- Do we need a constitution or can we just use the replaceable rules?
- Replaceable rules are workable for a simple, single-shareholder company, but become inadequate once you have multiple shareholders, want to restrict share transfer, plan to issue different share classes, or need governance provisions the Act's defaults don't cover. We assess this against your specific plans rather than defaulting to 'get a constitution' for every company.
- Can we adopt some replaceable rules and a custom constitution for the rest?
- Technically yes, but we generally advise against a partial hybrid because it creates real uncertainty about which version of a rule governs a given situation. A complete bespoke constitution or full reliance on the replaceable rules is cleaner.
- What happens if our constitution and shareholders agreement say different things?
- They can create a genuine conflict — a share transfer that's valid under the constitution could still breach the shareholders agreement and expose the transferring shareholder to a contractual claim. We draft the two documents together specifically to avoid this.
- How do we create different classes of shares?
- The constitution needs to expressly define each class and the specific rights attached to it — voting, dividend and capital return rights particularly — since the replaceable rules assume a single class of ordinary shares and don't provide default terms for preference or non-voting shares.
- Do we need to lodge our constitution with ASIC?
- No. A constitution is a company's internal document and generally isn't lodged with ASIC, but it must be kept with the company's records and made available to members on request under the Corporations Act.
