An alternate director is a person a company director appoints to stand in for them, exercising some or all of that director’s powers while they’re unavailable. In Australia, the default rules sit in section 201K of the Corporations Act 2001 (Cth), but your company constitution can change them or switch them off entirely.
Here’s the catch. Most directors only think about an alternate when they’re already packing for six weeks overseas or heading into surgery next Tuesday. And many assume an alternate director will keep the company running if the worst happens. It won’t. Let’s fix both problems while you still have time to plan.
- An alternate director acts with your powers, not their own. Under s 201K, anything they do within the appointment counts as if you did it.
- The other directors must approve the appointment. That’s the default rule. Your constitution can set a different process.
- Sole director and sole shareholder? The default rule doesn’t apply to you. You need a constitution that allows alternates before you can appoint one.
- ASIC needs to know within 28 days. Your alternate also needs a director ID before they act in the role.
- An alternate director is not a succession plan. The appointment rides on yours, so a will and an enduring power of attorney do the heavy lifting if you die or lose capacity.

What can an alternate director actually do?
Whatever you hand them, and nothing more. Section 201K lets you give an alternate “some or all” of your powers for a specified period. Once they act within that scope, their decisions bind the company exactly as yours would.
In practice, an alternate director can attend board meetings, vote, sign circulating resolutions and receive board papers. If you ask the company to send them notice of directors’ meetings, it has to (s 201K(2)).
What they can’t do is exceed your powers. You can narrow the role, say to voting at one meeting or approving one transaction. You can’t give your alternate powers you don’t hold yourself. That’s a common misreading worth clearing up early.
Alternate director vs director: what’s the difference?
A director holds office in their own right. An alternate director’s authority is borrowed. It exists only because a particular director appointed them, and it only covers what that director could do.
Legally, though, the line blurs once they step in. The Act’s definition of “director” includes an alternate who is acting in that capacity. So when your alternate is in the chair, they carry the same duties and the same personal exposure as you.
When should you appoint an alternate director?
Use an alternate director for a gap with an end date. Think extended travel, parental leave, a planned medical procedure, or a board where an investor’s nominee director can’t make every meeting.
Self-managed super funds with a corporate trustee are another common use. If a member-director moves overseas for a while, an alternate in Australia can keep decisions moving. Be careful here. If the alternate just signs whatever the overseas director emails through, the fund’s central management and control may still sit offshore, which puts its complying status at risk. Get SMSF-specific advice before relying on this.
When should you rethink? If the absence has no end in sight, appoint a proper director or step down. An open-ended alternate arrangement leaves you carrying responsibility for decisions you’re no longer close to.
Can your company appoint an alternate director?
Check your rules before you check your calendar. Which rules govern your company decides whether you can appoint an alternate at all, and who has to say yes.
| Your company | Can you appoint an alternate director? | Who approves it? |
|---|---|---|
| Uses the replaceable rules and has two or more directors | Yes, under s 201K | The other directors |
| Has a constitution that deals with alternates | Yes, on the constitution’s terms | Whoever the constitution names |
| Has a constitution that is silent on alternates | Yes, the replaceable rule fills the gap | The other directors |
| Has a constitution that excludes alternates | No, not until you amend it | Shareholders, by special resolution, to amend |
| Pty Ltd with one person as sole director and sole shareholder | Only if your constitution allows it | As set out in the constitution |
That last row catches a lot of founders. According to ASIC’s guidance on the replaceable rules, those rules don’t apply to a proprietary company where the same person is the sole director and the sole shareholder. No replaceable rules means no s 201K.
A sole director with other shareholders sits in a grey zone. Section 201K needs “the other directors'” approval, and you don’t have any. Don’t build your contingency plan on a technicality. Put a clear alternates clause in a company constitution and the question disappears.
One myth worth busting: you’ll read online that a shareholder resolution is enough to appoint an alternate director. Under the replaceable rule, it isn’t. The appointing director makes the appointment and the other directors approve it. If you’re unsure which set of rules you run on, our guide to constitutions versus replaceable rules walks through it.
How to appoint an alternate director, step by step
If your paperwork is in order, the whole process takes an afternoon. Here’s the sequence that keeps it clean.
1. Confirm your constitution allows it
Read the alternates clause, if there is one. Look for who can be appointed, who approves, whether the alternate can also be an existing director, and how the appointment ends. Use the table above if your constitution is silent.
2. Choose someone you’d trust with the chequebook
Your alternate must be at least 18 and not disqualified from managing corporations. Beyond that, pick someone who understands the business and has time to read board papers. A loyal friend who signs anything is a liability for both of you.
3. Make sure they have a director ID
Once they act in the role, your alternate is an “eligible officer” and needs a director ID, as the Australian Business Registry Services confirms. They must apply personally. Nobody can do it for them, so build in time for this before their first meeting.
4. Get their written consent
Section 201D requires a signed consent before anyone becomes a director, and the company keeps it on file. A Consent to Act as Director takes a few minutes to complete.
5. Put the appointment and approval in writing
Section 201K(5) says the appointment must be in writing and a copy given to the company. Record the other directors’ approval in the same document. A directors’ resolution to appoint an alternate director does both jobs at once.
Spell out the terms. Name the director being replaced and set the start and end dates. List the powers the alternate can use and any limits, such as a spending cap. Note whether they should get meeting notices. Vague terms are where disputes start.
6. Notify ASIC within 28 days
Within 28 days, the company must lodge the alternate’s details and the terms of the appointment with ASIC (s 205B(2)). That’s done through a change to company details, the same Form 484 process you’d use for any new officeholder. Miss the deadline and ASIC charges late fees.
7. Update your bank and signing arrangements
This is the step everyone forgets. Your bank won’t take instructions from an alternate just because the company says so. Lodge the appointment with your bank, update your internal registers, and tell your accountant, so the alternate can actually do the job you appointed them for.
Does an alternate director need to be registered with ASIC?
Yes. ASIC must be notified when an alternate director is appointed and again when the appointment ends (s 205B(2) and (5)). The alternate then shows up on the company’s ASIC record.
There’s one shortcut most directors don’t know about. If you give ASIC a fixed end date when you lodge the appointment, and the appointment ends on that date, you don’t need to lodge a second notice (s 205B(6)). Set an end date up front and you save yourself a form later.
Would you rather not deal with ASIC forms at all? Lawpath’s ASIC compliance service handles officeholder changes and drafts the supporting resolutions for you.
What duties does an alternate director take on?
The full set, for as long as they’re acting. That means the four core directors’ duties:
- Care and diligence (s 180)
- Good faith, in the company’s best interests and for a proper purpose (s 181)
- No improper use of their position (s 182)
- No improper use of company information (s 183)
Most guides leave off the duty that bites hardest: the duty to prevent insolvent trading (s 588G). An alternate who approves new debts while the company can’t pay its bills can be personally liable. “I was only filling in” is not a defence.
Your alternate also owes these duties to the company, not to you. If they think one of your standing instructions is a bad idea for the business, they’re entitled to vote against it. Pick someone whose judgement you’d accept on the days you disagree.
And you don’t get to switch off. Courts have long expected appointing directors to keep an eye on what their alternate is doing. Ask for a short written update after every meeting they attend.
Can an alternate director sign documents?
Yes, if signing falls within the powers you gave them. Because an alternate acting in the role counts as a director, they can sign under section 127, for example alongside another director or the company secretary.
Expect friction from the other side of the table. Banks, landlords and lenders will want proof the alternate was validly appointed and was acting on the day they signed. Keep the signed resolution and the ASIC confirmation somewhere you can send in two minutes. Deals stall on paperwork far more often than on law.
Alternate director vs power of attorney vs proxy: which one do you need?
These three get mixed up constantly. They solve different problems.
| Alternate director | Power of attorney | Proxy | |
|---|---|---|---|
| Who uses it | A director | An individual, for their personal affairs | A shareholder |
| What it covers | Board decisions, within the director’s powers | Your personal financial or legal decisions | Voting at a shareholders’ meeting |
| Does the person act as a director? | Yes, while acting | No | No |
| ASIC notification? | Yes, within 28 days | No | No |
| Survives your death? | No | No | Depends on the timing of notice to the company |
Remember this: your power of attorney can’t sit on your board. It deals with you as a person. If you lose capacity as a sole director and shareholder, your attorney may be able to appoint a new director under s 201F, but they can’t step into the role simply by holding the power. Get advice on how your documents work together.
Will an alternate director keep your company running if something happens to you?
No, and this is the most expensive misunderstanding in this whole topic. An alternate director exercises your powers. If you die, resign or are disqualified, you stop being a director, and most constitutions end the alternate’s appointment at the same moment. Even where yours doesn’t, there are no powers left to borrow.
Loss of mental capacity is murkier. Depending on your constitution, your directorship may end automatically, which takes your alternate down with it. Either way, the alternate is the wrong tool for the job.
For a sole director and sole shareholder, the law already has a fallback. Under s 201F, if you die or lose mental capacity, your personal representative or trustee can appoint a new director. The catch is speed. With a valid will, your executor can act relatively quickly. Without one, a family member has to apply to the Supreme Court first, and the company can sit frozen for months.
So the real succession kit for a one-person company looks like this: a will naming an executor you trust, an enduring power of attorney, and a constitution that spells out what happens next. An alternate director is a holiday plan, not a life plan.
Where alternate director appointments go wrong
Most problems with alternates aren’t legal puzzles. They’re admin gaps that show up at the worst moment. Watch for these:
- The handshake appointment. A director tells the board “Sam’s covering for me” and nothing gets signed. Every decision Sam makes is now open to challenge.
- The forever alternate. An appointment “until further notice” that nobody reviews for three years. Set an end date and renew it if you need to.
- The missing director ID. The alternate turns up to their first meeting without one, and the company has an eligible officer acting without it.
- The rubber stamp. An alternate who votes however the absent director texts them hasn’t met their own duties, and the absent director hasn’t really handed over.
- The wrong tool. Using an alternate to cover a permanent exit. If you’re not coming back, resign and appoint a director properly.
How do you end an alternate director’s appointment?
Under the replaceable rule, you can end it whenever you like (s 201K(4)). Do it in writing and give the company a copy (s 201K(5)). Then notify ASIC within 28 days, unless the appointment simply reached the end date you lodged at the start.
Close the loop with your bank and anyone else who has the alternate on file. A former alternate who still appears on a bank mandate is an accident waiting to happen.
Alternate director FAQs
What is an alternate director of a company?
An alternate director is someone a director appoints to exercise some or all of their powers for a set period, usually while they’re away. Their decisions bind the company as if the appointing director made them, and they carry full director duties while acting.
Who approves the appointment of an alternate director?
Under the replaceable rule in s 201K, the other directors approve it. Your constitution can change that. A shareholder resolution on its own doesn’t satisfy the replaceable rule.
Can a sole director appoint an alternate director?
Only if the company’s constitution allows it. The replaceable rules don’t apply where one person is both sole director and sole shareholder of a Pty Ltd, and s 201K needs other directors to approve. Add an alternates clause to your constitution first.
Does an alternate director need a director ID?
Yes. An alternate who acts in the role is an eligible officer and needs a director ID. They must apply for it themselves through ABRS, so sort it out before their first meeting.
Do you have to tell ASIC about an alternate director?
Yes, within 28 days of the appointment, including the terms of the appointment. You also notify ASIC when it ends, unless it ends on an expiry date you gave ASIC at the start.
Can an alternate director sign company documents?
Yes, if signing is within the powers you delegated. An alternate acting in the role counts as a director for s 127 execution. Keep the appointment resolution handy, because banks and counterparties will ask for it.
Is an alternate director personally liable?
They can be. While acting, an alternate owes the same duties as any director, including the duty to prevent insolvent trading. Being a stand-in doesn’t reduce their exposure.
Can an existing director be an alternate for another director?
Nothing in s 201K stops it, and many constitutions allow it. Check how your constitution handles voting, because some give the director a separate vote for each role and others don’t.
What happens to an alternate director if the appointing director dies?
The alternate loses the powers they were exercising, because those powers belonged to the director who died. For a sole director and shareholder, the executor appoints a new director under s 201F, which is why a will matters.
How long can an alternate director act?
For whatever period the appointment specifies, and you can end it early at any time. Set a clear end date. It keeps the arrangement honest and can save you an extra ASIC notice.
Get your alternate director sorted before you need one
If you’ve read this far, you’re already ahead of most directors, who only think about this the week before they fly out. You don’t need a governance overhaul. You need a check of your constitution, one signed resolution, a consent form and an ASIC update. If any of it feels unclear, one of our corporate lawyers can look over your setup.
