What Is An Authority To Act Form?

If you’ve ever needed someone to speak to a government agency, bank, supplier or insurer on your behalf, you’ve probably been asked for an “Authority To Act.”

For Australian businesses, this simple document can save hours of back-and-forth and help things get done faster - provided it’s drafted correctly and accepted by the organisation you’re dealing with.

In this guide, we’ll explain what an Authority To Act form is, when you might need one, what to include, how to sign it properly, and common traps to avoid. By the end, you’ll know how to put one in place confidently and protect your business when others are acting in your name.

Authority To Act: What It Is (And What It Isn’t)

An Authority To Act form is a written permission that authorises a person or organisation (your “authorised representative” or “agent”) to interact with a third party on your behalf for a defined purpose.

Think of it as a targeted permission slip. It lets your nominated person request information, provide instructions, make enquiries, or even sign certain documents - but only within the scope you set out.

It’s not the same as handing over control of your business. And it’s not a general power of attorney. It’s a practical, limited authorisation designed to keep your operations moving, especially when founders or directors can’t attend to everything themselves.

Common situations where businesses use an Authority To Act include:

• Allowing your accountant to speak with the ATO or your bookkeeper to deal with your software provider
• Authorising a lawyer to negotiate with a landlord or supplier
• Permitting a consultant to obtain information from your insurer, telco, or bank
• Enabling an internal staff member to handle a specific contract renewal or service issue

If you want a ready-to-use, tailored document, many teams ask us to prepare an Authority To Act Form that aligns with the requirements of the recipient (for example, a bank or government agency).

When Do You Need An Authority To Act Form?

You’ll generally need an Authority To Act whenever the third party you’re dealing with won’t accept instructions from anyone other than the business owner, a director, or a listed contact - and you want someone else to act for you.

Typical Scenarios

• Government and regulators: ATO, ASIC, state revenue offices, licensing bodies and local councils often require written authority before discussing your account or application with a representative.
• Financial services: Banks, merchant facilities, payment processors and insurers may require an authority before they’ll release information or take instructions.
• Utilities and telcos: Electricity, gas, NBN and mobile providers typically need authority before making changes or disclosing account details.
• Landlords and suppliers: Commercial landlords or key suppliers often ask for proof that your representative is permitted to negotiate terms or resolve disputes.

Different organisations have different rules. Some will accept your own letter; others require their specific form. If you’re not sure, check their requirements first - or have your lawyer tailor your authority to match what they’ll accept.

Where you need a more formal letter format (instead of a form), it’s common to use a short letter of authority on your letterhead containing the same core details.

What Should An Authority To Act Form Include?

Clear, precise drafting is key. The aim is to authorise what you need - no more, no less - so third parties feel comfortable relying on it and you remain protected.

Essential Elements

• Parties: Your business’ details (legal name, ABN/ACN) and the full name and contact details of your authorised representative.
• Recipient: Who the authority is addressed to (e.g. the ATO, a bank, your landlord, a specific supplier).
• Scope: Exactly what the representative can do (e.g. “make enquiries and receive information”, “negotiate commercial terms”, “sign renewal documentation up to $X”). Avoid vague or unlimited language unless you truly intend it.
• Information access: Confirm whether the representative may access confidential or personal information, and any limits.
• Duration: A clear start date and end date, or an event that ends the authority (e.g. “until the lease is executed” or “for 6 months from the date of this letter”).
• Revocation: How you can revoke the authority and the effect of revocation (usually in writing to the recipient and the representative).
• Sign-off: Proper execution by the business (and witnessing if required by the recipient).

Helpful Options To Consider

• Liability and limits: Clarify that your representative cannot incur obligations beyond the specified scope or threshold (e.g. can’t agree to price increases beyond a percentage without director approval).
• Conflicts and compliance: Require the representative to disclose any conflicts of interest and to comply with applicable laws (privacy, confidentiality, consumer law).
• Sub-authority: State whether the representative can delegate their authority (most businesses prefer “no” unless necessary).
• Document handling: If the representative will share or store sensitive data, make sure your Privacy Policy and confidentiality expectations are clear.

How To Sign And Use The Authority Properly

Even the best-drafted authority can be rejected if it’s not signed the right way. Make sure you follow the organisation’s execution requirements and keep a record of what you’ve issued.

Execution Tips

• Companies: If you operate through a company, consider executing in line with section 127 of the Corporations Act (e.g. two directors, or a sole director/secretary). Many recipients are familiar with these rules and will rely on them. You can read more about signing documents under section 127.
• Sole traders and partnerships: Sign in accordance with your business structure and any partnership agreement. If in doubt, signatories should be those with clear authority to bind the business.
• Witnessing: Some organisations require a witness or certified ID alongside the authority. If witnessing is requested, our guide on who can witness a signature is a useful reference.
• Electronic signatures: Many recipients accept e-signatures, but not all. Check their policy and ensure you’re complying with the rules for signing documents in Australia.

Operational Best Practice

• Use the right channel: Send the authority to the organisation through their preferred channel (secure portal, email, or in-branch).
• Keep a register: Maintain a simple register of current authorities (who, what, when it expires, and how to revoke). This avoids outdated permissions lingering.
• Reconfirm scope: Brief your representative on limits and escalation points (e.g. “call a director if X happens”).
• Revoke when done: When the task is complete, notify the recipient that the authority is revoked and update your register.

Common Risks And How To Avoid Them

Authorising someone to act for your business carries risk if boundaries aren’t clear. Here are the issues we see most often - and how to mitigate them.

Risk 1: Overly Broad Authority

Granting “full authority for all matters” may be convenient, but it’s unnecessary in most cases and invites problems.

Fix: Narrow the scope. State the purpose, the exact actions permitted, financial limits and the specific account or agreement covered.

Risk 2: No End Date

Open-ended authorities are easy to forget about, leaving a third party relying on an old document years later.

Fix: Use a clear expiry date or a completion trigger. Put a reminder in your diary to review or revoke it.

Risk 3: Unclear Signing Power

Some representatives need to sign forms or minor documents to finalise a matter. If that’s allowed, spell it out.

Fix: Say exactly what can be signed (e.g. “renewal forms and standard service orders, but not contracts exceeding $X”).

Risk 4: Privacy Concerns

If your representative will access personal or confidential information, you’re still responsible for compliance with the Privacy Act and contractual confidentiality obligations.

Fix: Limit information access to what’s necessary and ensure your internal policies (including your Privacy Policy) and confidentiality requirements are clear. For external consultants, consider a separate Non-Disclosure Agreement alongside your authority.

Risk 5: Recipient Won’t Accept The Authority

Some organisations insist on their own form or additional identification checks.

Fix: Confirm requirements early. If they accept your document, tailor it to match their requested wording and execution format.

Authority To Act Vs Other Legal Instruments

It’s helpful to understand how an Authority To Act compares with other ways of authorising people or managing responsibility.

• Authority To Act vs Power of Attorney: A Power of Attorney is a broader legal instrument giving someone legal power to make decisions for you. In business operations, you’ll usually use an Authority To Act because it’s narrower and purpose-specific. If you think broader powers are required, get legal advice before proceeding.
• Authority To Act vs Deed: An Authority To Act is typically a simple letter or form. In some higher-risk scenarios, parties use a deed format for extra formality. If you’re weighing this up, our overview of what is a deed explains how deeds differ from simple agreements.
• Authority To Act vs Contractual Appointment: For ongoing roles (like appointing a sales agent or distributor), a formal agreement is often better than a one-page authority. For one-off tasks or dealing with a single third party, the authority is usually sufficient.

Step-By-Step: Preparing Your Authority To Act

1) Confirm The Recipient’s Requirements

Ask the organisation what they need: their own form, certified ID, specific wording, or a timeframe. This avoids rework later.

2) Define The Scope And Limits

Write a short description of what the representative must do, the accounts or matters involved, and any financial caps or signing permissions.

3) Draft The Document

Include parties, scope, duration, revocation, and any privacy/confidentiality notes. If a formal letter is required, draft it on your letterhead. If a reusable template suits your operations, ask us to tailor an Authority To Act Form that your team can quickly complete for different recipients.

4) Execute Correctly

Sign in line with your structure and the recipient’s rules. For companies, following section 127 helps recipients rely on the authority - see our guide to signing under section 127. If a witness is needed, check who can witness a signature in Australia.

5) Send, Track, Revoke

Send through the required channel. Record the issue date and expiry in your register. When the task is finished, send a revocation notice and file the confirmation.

Practical Examples Across Industries

To make this concrete, here are a few scenarios we regularly see in Australian businesses.

Accountant Dealing With ATO And Software Providers

You authorise your external accountant to speak with the ATO about your BAS issues and to access your bookkeeping software account to reconcile transactions. Your authority allows information access and lodgement support, but not the power to enter into loans or payment plans above an agreed threshold without your approval.

Lawyer Negotiating A Lease Renewal

You give your lawyer authority to make enquiries and negotiate non-binding commercial terms for a lease renewal, sign standard forms, and correspond with the landlord’s agent. The authority expressly excludes signing the final lease without director sign-off.

Staff Member Handling Telco Accounts

Your operations manager is authorised to manage your telco accounts, order SIM replacements and approve plan changes up to a set dollar value. The authority lasts 12 months and is revoked if the staff member leaves the business.

Frequently Asked Questions

Does An Authority To Act Need To Be Witnessed Or Notarised?

Not usually, but some organisations require a witness or certified ID. Always check the recipient’s rules and follow Australia’s general requirements for signing documents if you’re unsure.

Can A Company Secretary Or Manager Issue An Authority To Act?

They can, provided they have actual authority within the business to do so and you execute the document correctly. Many recipients will ask for company execution that aligns with section 127 or for evidence of the person’s authority.

Is An Authority To Act Legally Binding?

Yes - it’s a written permission the recipient can rely on, within its scope. Keeping the scope and duration clear reduces the risk of misunderstandings and helps the recipient know exactly what they can accept.

Can We Reuse The Same Authority For Different Organisations?

You can maintain a template and adapt it, but many organisations have their own forms. Having a well-drafted template on hand speeds things up while still allowing you to meet specific requirements.

What If We Need A Formal Appointment Instead?

For ongoing, repeat roles (like agents or distributors), you’ll usually want a separate contract, sometimes accompanied by confidentiality terms. If you need a simple permission letter for a one-off matter, a letter of authority or tailored form typically does the job.

Key Takeaways

• An Authority To Act form gives a representative permission to deal with a specific organisation on your behalf for a defined purpose and time.
• Include the essentials: parties, scope, limits, information access, duration, revocation and proper execution details so the recipient can rely on it.
• Check the recipient’s requirements early - some demand their own form, ID checks or witnessing before they’ll act.
• Manage risk by narrowing the scope, setting financial caps, limiting information access and using NDAs where appropriate.
• Execute correctly (especially for companies) and keep a simple register to track current authorities and revocations.
• Use a reusable, tailored template to speed up future requests while staying compliant with privacy and confidentiality obligations.
