Anatomy of a change of control clause in Australian contracts

You are about to sign a long-term supply agreement and there it is in the boilerplate: a clause headed "Change of Control". The customer's lawyer wants the right to walk away if your business changes hands. Or you are the one selling, and a counterparty has just told you that their change of control clause means your buyer will have to renegotiate every major contract before the deal can complete.

A change of control clause is a risk-allocation device. It lets a party that entered a contract trusting a particular owner get notice, demand consent, renegotiate, or walk away if that owner changes. It operates alongside, not instead of, the other transfer mechanisms in the contract, such as assignment and novation, and it connects to the documents that sit behind your company, like a shareholders agreement and a constitution. A well-drafted clause protects both sides. A poorly drafted one can block a sale, trigger a termination at the worst possible moment, or hand a counterparty a veto it never intended to have.

What goes into a change of control clause

Every change of control clause has three working parts: a definition of what counts as control, a description of the events that change it, and a set of consequences that follow. The drafting choices in each part are where deals are won and lost.

Defining who controls the company

The definition is the heart of the clause. Australian contracts commonly borrow the concept of control from the Corporations Act. Under s 50AA(1) of the Corporations Act 2001 (Cth), an entity controls another if it has the capacity to determine the outcome of decisions about the second entity's financial and operating policies. The test is about capacity, not about whether the power is actually exercised, and s 50AA(2)(a) directs attention to the practical influence an entity can exert rather than the rights it can enforce.

Most negotiated definitions then set a bright-line threshold on top of that concept:

Shareholding threshold: a person acquiring more than 50% of the issued shares or of the voting power of the company.
Board control: the power to appoint or remove a majority of the directors.
Effective control: the ability to influence decisions through agreements, options, or other arrangements, even without a majority shareholding.

The trap on the other side of the table is a definition that only catches direct shareholding. If the clause ignores board control and agreements, a buyer can control the company through a casting vote and a convertible note without ever tripping the trigger.

Catching indirect control

A sale of a parent company changes who controls its subsidiaries even though the subsidiary's share register never moves. Clauses that want to catch this use phrases like "directly or indirectly" and trace control up and down holding structures. This is one reason the statutory test is a useful model: because s 50AA looks at practical capacity to determine outcomes rather than the formal register, it reaches arrangements that a naive shareholding test would miss. If indirect control matters to your relationship, the clause needs to say so explicitly, or a restructure one level up will sail straight past it.

The trigger events

Not every ownership change trips the clause; the definition decides. The usual triggers are:

Share sale: a buyer acquiring shares, often a majority stake, with control changing at completion. This is the classic scenario.
Group restructure: moving shares up or down a holding structure, which is caught only if the definition covers changes "directly or indirectly".
Options, convertibles and voting arrangements: rights to appoint directors, exercise vetoes, or acquire a majority on conversion can constitute a change of control before any shares move.
Board or management changes: broader commercial definitions can include changes to a majority of the board or senior management. Less common in small business, but it appears in contracts with banks and strategic partners.
Asset sale: usually does not trigger the clause at all, because the company itself does not change hands. The complication is different: each contract must be transferred to the buyer separately, which is where assignment and novation consent becomes the real gate.

Anti-avoidance language

Parties sometimes structure around a clause. Staggered transfers that each stay below the threshold, nominee holdings, and proxies can all be used to avoid a trigger. Anti-avoidance drafting aggregates what would otherwise be split:

Associates and concert parties: counting shares held by persons acting together with the buyer.
Future voting power: counting options and convertible instruments that will mature into votes.
Series of transactions: treating a sequence of transfers as one change of control.

This mirrors how the Corporations Act counts voting power. Under s 610 of the Corporations Act 2001 (Cth), a person's voting power is calculated by aggregating the votes attached to shares the person or an associate has a relevant interest in. Drafting an anti-avoidance provision on the same aggregation logic keeps the clause consistent with the statutory framework.

There is also a statutory gate worth knowing if the company may one day list. Under s 606 of the Corporations Act 2001 (Cth), a person must not acquire a relevant interest in voting shares of a listed company, or an unlisted company with more than 50 members, if it takes their voting power from 20% or below to more than 20%, unless an exception in s 611 applies. A contractual clause sits alongside that regime rather than replacing it.

Carve-outs and exclusions

Most clauses list events that do not count as a change of control. Typical exclusions:

Internal restructures: transfers within the same ultimate holding company group.
Listing and capital raises: a widely dispersed raise or public listing that dilutes rather than concentrates control.
Founder and family transfers: estate planning or transfers between family members.
Employee share schemes: issuance or transfer of shares under an employee incentive plan.

Each carve-out narrows the protection the clause gives, and each missing carve-out creates administrative burden for events nobody is worried about. The balance is a commercial choice, not a legal one, and it should reflect how the business actually plans to grow.

What happens when the clause is triggered

The consequences are where the clause bites. They need to be proportionate to the risk, or they will either spook counterparties or be ignored in practice.

Notice obligations

The notice provision sets out what the changing party must tell the other side, and when:

Timing: whether notice must be given before completion, or only promptly after.
Content: the identity of the new controller, a summary of the transaction, and evidence of financial standing or continuity of service.
Timeframes: the number of business days allowed, and what happens if notice is not given at all.

For a seller, advance-notice obligations need to be workable alongside confidentiality. It is common to stage the process: early anonymous notice, detailed disclosure under a non-disclosure agreement, then formal notice shortly before completion.

If the contract requires consent to a change of control, the standard of that consent is the most negotiated line in the clause:

Not to be unreasonably withheld or delayed: the common compromise. It protects the counterparty without giving it a veto.
Absolute discretion: what the other side may push for. It deters buyers and investors, because consent can be withheld for any reason at all.
Deemed consent: consent is taken to be given if the counterparty does not respond within an agreed period. Useful for keeping the deal moving.

Consent clauses should also say which events need consent and which are carved out. An internal restructure within the same ultimate parent should not require a consent dance.

Termination rights

The termination limb says what happens if the clause is triggered and the counterparty is unhappy:

For convenience or for cause: whether termination is available on notice, or only where the change of control has a material adverse effect on the counterparty.
Immediate or after a cure period: whether the counterparty can terminate on the spot or must give the new controller a chance to fix the concern.
Costs of termination: wind-down obligations, payment of outstanding amounts, and return of confidential information.

The trap here is an automatic termination right with no qualifier. If a change of control clause terminates a key customer contract automatically, the company can lose its largest revenue stream the day its founders sell, even though the buyer was perfectly capable of performing. Cure periods and materiality qualifiers soften that risk.

Renegotiation and extra security

Termination is not the only consequence on the menu:

Price or terms review: for long-term supply, an option to renegotiate pricing or service levels, rather than an automatic termination right.
Additional security: for finance or high-credit-risk arrangements, the right to require guarantees or additional security from the new controller.
Step-in rights: in some contracts, the counterparty can step in to perform the obligations itself if the new controller fails.

These are often the proportionate middle ground. The counterparty gets comfort, and the deal survives.

The fit with assignment and novation

Change of control and assignment are different mechanisms, and contracts that blur them cause confusion at the deal table. A change of control clause is triggered by a shift in who controls the company. Assignment transfers the benefit of the contract, and novation transfers the whole contract, obligations included, usually with the consent of the other party.

An asset sale is the clearest example. The company selling its business does not change control, so the change of control clause may not fire, but every contract being moved to the buyer needs to be assigned or novated, and each transfer may require the counterparty's consent. The drafting task is to coordinate the two regimes: consistent consent standards, aligned timeframes, and no double gates that let a counterparty withhold consent twice over the same transaction.

Optional clauses worth asking for

Some provisions sit alongside the change of control clause and are worth raising in negotiation when they fit the deal:

Change of control put option: common in loan documents, where the lender can require early repayment of the facility if control of the borrower changes.
Drag-along and tag-along rights: in a shareholders agreement, letting a majority seller compel minority holders to join a sale, and letting minority holders sell alongside a majority seller on the same terms.
Good leaver and bad leaver provisions: in founder and investor agreements, setting what happens to a founder's shares when they leave, which directly affects who ends up controlling the company.
Board representation rights: an investor's right to appoint a director, which can interact with a definition of control built around board composition.
Takeover and listing exemptions: for a company heading to an IPO, carving widely dispersed transactions out of the definition, consistently with the s 606 regime.

How an Artificer Legal lawyer reviews your change of control clause

Change of control provisions sit at the intersection of your contracts, your security arrangements, and your governance documents, which is why a review usually starts well before the clause itself. An Artificer Legal practitioner would map your critical contracts, customers, suppliers, lenders, landlords and software platforms, and flag which ones contain change of control, consent, assignment or termination rights. That map becomes the timetable for any future sale.

Then the clause work begins. We would check the definition for balance: narrow enough to avoid triggering on benign restructures, broad enough to catch indirect control and control by agreement. We would review the notice periods, the consent standard, and the default position if no response comes. We would test the clause against your shareholders agreement and constitution, because pre-emptive rights, drag and tag mechanisms and transfer restrictions all interact with a change of control trigger. And where security is involved, we would check the registrations on the Personal Property Securities Register, established under s 147 of the Personal Property Securities Act 2009 (Cth), to see whether a change of control defaults or releases any registered security interest.

If a transaction is already on the horizon, we would also negotiate the carve-outs and assurances that let the deal complete: consent standards that cannot be used as a kill switch, cure periods, and covenants about continuity of service and financial standing. The goal is protection that survives contact with a real deal.

Why the definition is where disputes are won or lost

If there is one drafting choice that separates a change of control clause that works from one that does not, it is the definition of control. A definition that only catches direct shareholding lets a parent sale, an option structure, or a board coup change who really runs the company without ever firing the trigger. A definition drawn too broadly turns every internal restructure into a default under half your contracts. Everything else in the clause, the notice, the consent, the termination right, hangs off the definition, because if the trigger never fires, none of the consequences ever apply. When you review a change of control clause, start at the definition and work outwards.

The practical picture to keep in mind: a change of control clause exists because long-term contracts are made with people, not just companies, and it reallocates the risk when the people change. Model the definition on the capacity-based concept in s 50AA of the Corporations Act, set an explicit threshold, catch indirect control and control by agreement, add anti-avoidance language and sensible carve-outs, and make the consequences proportionate, with notice and consent mechanics that a real transaction can actually comply with. Coordinate the clause with your assignment and novation provisions and your shareholders agreement, and before any sale, map your contracts and check the PPSR so there are no last-minute surprises. A lawyer's review at that point is cheaper than a consent withheld on the day before completion.
