When Should You Review Your Company Constitution?

Your company constitution often gets signed at setup, filed away, and forgotten until something goes wrong. That is usually when founders discover the document no longer matches how the business actually operates. Common mistakes include using an old template that does not deal properly with new investors, assuming the replaceable rules are enough without checking the gaps, and forgetting to update voting, share transfer, or director decision rules before a dispute starts.

A constitution review for companies matters most when your business is growing, changing ownership, raising capital, or formalising decision-making. The right time to review it is usually before you sign a shareholders agreement, before you issue new shares, before a co-founder exits, or before you spend money on a restructure. This guide explains what a company constitution does in Australia, when it should be reviewed, what to look for, and the mistakes that commonly create founder disputes and governance problems.

Overview

A company constitution is one of the main internal rulebooks for an Australian company. It can affect who controls decisions, how shares can be issued or transferred, what happens if a founder leaves, and whether your paperwork matches the way the business is actually being run.

A sensible review focuses on whether the constitution still fits your ownership, governance and growth plans, not just whether the document exists.

• Whether the constitution matches your current share structure and classes of shares
• How directors make decisions, appoint alternates, and deal with conflicts
• Voting thresholds for ordinary and special resolutions
• Rules for issuing shares, pre-emptive rights, and shareholder approvals
• Share transfer restrictions, founder exits, and what happens on death or incapacity
• How meetings, notices and written resolutions can be handled
• Whether the constitution aligns with any shareholders agreement
• Whether older clauses still reflect current Corporations Act requirements and modern business practice

What Constitution Review for Companies Means For Australian Businesses

A constitution review for companies means checking whether your company’s internal rules are still legally workable and commercially sensible for the business you have now. For Australian businesses, that usually means comparing the constitution against the Corporations Act 2001 (Cth), your current cap table, your decision-making processes, and any separate founder or investor agreements.

A proprietary company in Australia can operate under the replaceable rules in the Corporations Act, under a constitution, or under a combination of both. Many companies adopt a constitution at incorporation because it gives more tailored rules than the default legislative framework. The problem is that a constitution written for a two-founder startup may be a poor fit once you bring in investors, appoint additional directors, create an employee share plan, or restructure ownership.

Your constitution does not usually regulate customer contracts, privacy compliance, trade marks, or employment contracts directly. But it often affects the authority to approve those matters. For example, if the constitution requires certain shareholder approvals before shares are issued or before a major decision is made, ignoring it can create serious governance problems even where the commercial deal seems straightforward.

What a company constitution usually covers

The exact wording varies, but most constitutions deal with the core mechanics of running the company.

• Appointment and removal of directors
• Director powers and board decision-making
• Share issue procedures and shareholder rights
• Classes of shares and attached rights
• Dividend rules
• Meetings, notices and voting procedures
• Transfers of shares and restrictions on disposal
• Use of written resolutions
• Indemnities and insurance for officers, within legal limits

Why it matters in practice

Founders often focus on external paperwork, such as supplier contracts, customer terms, privacy policies or lease documents. Internal governance gets less attention because it feels less urgent. This is where founders often get caught.

If your constitution says one thing and the business operates another way, the gap can become expensive. A shareholder may challenge a share issue. A departing founder may argue a transfer restriction does not apply. An investor may insist on changes before they sign. A bank, buyer or due diligence adviser may pick up governance defects during a funding round or sale process.

A review is not just about legal compliance. It is also about reducing friction. A clear constitution can help the business make decisions faster, avoid avoidable founder conflict, and support future documents such as a shareholders agreement, subscription agreement, employee incentive plan rules, or board approvals.

Constitution versus shareholders agreement

Your constitution and shareholders agreement should work together. They are not the same thing.

A constitution is a statutory contract between the company, its shareholders and its directors. A shareholders agreement is a separate contract between the shareholders, and sometimes the company as well, covering commercial rights and obligations in more detail.

Many businesses review the constitution at the same time they negotiate a shareholders agreement because the two documents can overlap on issues such as:

• pre-emptive rights
• drag along and tag along rights
• board appointment rights
• reserved matters requiring shareholder approval
• share transfer restrictions
• founder vesting or exit arrangements

If these documents are inconsistent, you may create uncertainty right when you need clarity most.

When This Issue Comes Up

The best time to review your constitution is before a major company event, not after a disagreement starts. Most Australian businesses do not need to review it every month, but they should revisit it when the company structure, ownership or governance changes.

1. When you set up the company

A constitution should be reviewed at setup if you are not simply adopting a standard document without changes. This matters especially where there are multiple founders, unequal ownership, special voting rights, or a plan to bring in investors later.

Founders often rush company registration, get an ACN, set up an ABN, choose a business name and start trading. The governance documents are left on standard settings. That can be fine for a simple sole director, sole shareholder company. It is usually less fine where there are several stakeholders and different expectations about control.

2. Before issuing new shares

If you are raising money, issuing shares to a co-founder, or creating an employee equity arrangement, review the constitution first. The share issue rules in the document may require approvals, set pre-emptive processes, or assume only ordinary shares exist.

This is also the point where classes of shares can become relevant. If the constitution does not properly allow for preference shares, different voting rights, or conversion mechanics, investors may ask for amendments before they proceed.

3. When a founder joins or leaves

Founder exits are one of the most common triggers for a constitution review. The document may say little, or nothing useful, about compulsory transfers, valuation methods, leaver scenarios, or director removal.

Before you sign an exit deed or agree a buyback, check whether the constitution contains transfer restrictions, approval requirements, or procedural steps that must be followed. Missing those steps can create arguments later about whether the transfer was valid.

4. When investors or lenders are doing due diligence

Capital raises and acquisition deals often expose governance problems that have been sitting quietly for years. Investors and buyers will usually ask for your constitution, shareholder records, past resolutions and details of the current cap table.

If the constitution is outdated, inconsistent with other documents, or does not match the company’s actual share structure, the issue may delay the deal or force clean-up work under time pressure.

5. When the business changes size or decision-making style

A company with one working director does not need the same procedural framework as a company with a board, passive shareholders, and monthly management reporting. As the business grows, the constitution should still support how decisions are actually made.

That might mean reviewing:

• quorum rules for meetings
• written resolution procedures
• chair voting powers
• director appointment rights
• notice periods and practical meeting mechanics

6. Before a restructure, sale, merger or succession plan

If you are restructuring the business structure, preparing for a sale, planning succession, or moving ownership into a family trust or holding structure, review the constitution early. Transfer restrictions, share class issues and consent requirements can affect timing and costs.

This is also relevant before you sign a term sheet or heads of agreement. A commercial deal may assume transfers or approvals are simple when your constitution says otherwise.

7. When the document is simply old

An older constitution is not automatically invalid, but age is a good reason to review it. Businesses often inherit constitutions drafted for different ownership patterns, old administrative practices, or assumptions that no longer fit modern digital operations.

For example, older documents may be less clear on virtual meetings, circulating resolutions, or current governance expectations. They may also use inconsistent definitions or refer to concepts that do not align neatly with your current arrangements.

Practical Steps And Common Mistakes

A useful constitution review starts with your actual business, not just the wording on the page. The goal is to check whether the document still supports the people, ownership and decisions that exist now, and the changes you expect over the next phase of growth.

Step 1: Compare the constitution to reality

Start with the basics. Who owns shares today, who acts as directors, what approvals are commonly needed, and what changes are planned over the next 12 to 24 months?

Then compare that reality against the constitution and your company records. In practice, you should line up:

• the constitution
• the share register
• ASIC records
• past shareholder and director resolutions
• any shareholders agreement
• investment documents or subscription terms

If these documents do not match, fix the inconsistency before it becomes part of a larger transaction.

Step 2: Check the share provisions carefully

The main risk in many founder-led businesses sits in the share clauses. These provisions affect control, dilution and exit rights.

Review whether the constitution clearly deals with:

• how new shares can be issued
• whether existing shareholders get a first right to participate
• whether multiple classes of shares are allowed
• how class rights can be varied
• what restrictions apply to transfers
• whether directors can refuse to register a transfer

This matters before you bring in a strategic investor, issue advisory shares, or move ownership between related entities.

Step 3: Review governance and decision rules

Board and shareholder procedures should be practical enough to use. If your constitution requires formal steps no one follows, the company may be making decisions in a technically messy way.

Check whether the rules for meetings, notices and written resolutions suit the way your business actually operates. A small online business with directors in different states may need clear authority for virtual meetings and circulating resolutions. A growing SME with investor-appointed directors may need more defined reserved matters and quorum protections.

Step 4: Check for overlap with other business documents

Your constitution should not sit in isolation. Founders often forget that governance documents interact with other legal arrangements.

For example, if your business is expanding, you might also be reviewing:

• founder agreements
• shareholders agreements
• employee share plan rules
• commercial leases
• supplier or distribution contracts that need board approval
• privacy and data governance policies where certain officer approvals are required

The constitution does not replace these documents, but it can affect who has authority to approve them.

Step 5: Follow the amendment process properly

If the constitution needs changing, the process matters. A company usually amends or repeals its constitution by special resolution of shareholders. The exact procedure should be checked carefully against the Corporations Act and the existing constitution.

You should also make sure supporting records are updated. That can include minutes, shareholder resolutions, and related governance documents. If a change affects share rights or existing agreements, extra steps may be needed.

Common mistakes businesses make

The most common mistakes are not dramatic. They are small governance shortcuts that create larger problems later.

• Using a generic constitution without tailoring it to the ownership structure
• Assuming the constitution and shareholders agreement say the same thing
• Issuing shares before checking pre-emptive rights or approval rules
• Failing to review the constitution before a founder exit or dispute
• Amending the constitution without updating related resolutions and records
• Leaving outdated clauses in place because no one wants to reopen founder discussions

A practical example

Take a company that started with two founders holding ordinary shares and one sole director. Two years later, the business wants to raise capital, appoint another director, and offer equity to a senior hire. The old constitution says little about different share classes, does not align with the draft shareholders agreement, and gives directors broad discretion over transfers without a clear process.

If the business reviews the constitution before the raise, it can tidy up issue mechanics, transfer rules, meeting procedures and investor rights in one process. If it waits until documents are already being negotiated, the deal can become slower, more expensive and more tense.

How often should you review it?

There is no fixed annual legal requirement for most companies to review the constitution, but a periodic governance check is sensible. Many SMEs review it:

• when there is a funding round or investor discussion
• when ownership changes are proposed
• when a director joins or leaves
• when major governance documents are being updated
• every few years if the business has grown significantly since incorporation

If your business is also changing structure, expanding online, updating customer contracts, reviewing privacy compliance, or protecting its brand with a trade mark, that can be a good moment to check whether internal approvals and governance documents still line up. The constitution is not the place for every operational legal issue, but it should not become the weak point in a broader growth plan.

FAQs

Does every Australian company need a constitution?

No. Some companies rely on the replaceable rules in the Corporations Act instead. Many businesses still choose a constitution because it allows more tailored governance rules.

How do I know if my constitution is outdated?

A constitution is often outdated if it does not reflect your current shareholders, directors, share classes, investor arrangements, or decision-making processes. It is also worth reviewing if it was adopted years ago and has not been checked since major business changes.

Can a company change its constitution after registration?

Yes, usually by special resolution of shareholders. The amendment process should be checked carefully, and related company records should also be updated.

What is the difference between the replaceable rules and a constitution?

The replaceable rules are default governance rules set out in the Corporations Act. A constitution lets the company adopt its own rules, either instead of or alongside those default rules.

Should we review the constitution before a capital raise?

Yes. A capital raise is one of the clearest times to review it, because investors often focus on share issue mechanics, transfer rights, board rights, voting thresholds and consistency with any shareholders agreement.

Key Takeaways

• A company constitution should be reviewed when your ownership, governance or growth plans change, not just when a dispute arises.
