Leasing Authority Agreements in Australia

If a leasing agent is bringing you tenants, negotiating terms, or speaking to prospective occupiers on your behalf, the paperwork matters more than many landlords and business owners expect. A common mistake is signing the agent's standard form without checking whether it gives the agent exclusive rights for too long. Another is assuming the commission only applies if the agent introduces the final tenant, when the drafting may be much broader. A third is relying on verbal promises about marketing spend, reporting, or who can approve incentives.

A leasing authority agreement sets the rules for that relationship. It decides what the agent can do, what you will pay, how long the arrangement lasts, and what happens if the property is leased after the authority ends. Before you sign, you need to know where the commercial pressure points are and which clauses can create expensive surprises later.

Overview

A leasing authority agreement is the contract between a property owner or lessor and the agent authorised to market premises and secure a tenant. It is usually focused on commercial premises, such as office, retail, warehouse or industrial space, and it should clearly define the agent's authority, fees and limits.

• Whether the authority is exclusive, sole or non-exclusive
• Exactly what the agent is authorised to do, including advertising, negotiations and heads of agreement
• How commission is calculated, when it is payable and whether it applies after the authority ends
• Who pays marketing costs and whether there is a spending cap
• The term of the authority, renewal rights and termination process
• Any landlord approvals required before incentives, fitout contributions or lease terms are agreed
• How disputes, liability, indemnities and confidentiality are handled

What Leasing Authority Agreement Means For Australian Businesses

A leasing authority agreement gives an agent legal permission to act for you in finding and negotiating with prospective tenants. In practical terms, it is the document that decides who is allowed to market your premises, how far they can go in negotiations, and what you owe them if a lease is signed.

For Australian businesses, this usually comes up when you own commercial premises, hold an investment property through a company or trust, or control premises as part of a broader operating business. It can also matter if you are a head tenant looking to assign or sublease space, although that situation often requires separate landlord consent and should be checked carefully before any authority is given to an agent.

The agreement is not the lease itself. It sits earlier in the process, before you sign a commercial lease, and deals with the agent relationship rather than the tenant relationship. That distinction matters because business owners often focus on rent, term and fitout in the lease, but forget that the authority agreement can lock in commission obligations and agent rights before the tenant documents are even drafted.

What does the agent usually have authority to do?

The answer should be specific. A good leasing authority agreement does not just say the agent may “lease the property”. It should spell out the actual scope of authority so there is less room for argument later.

This often includes:

• marketing the premises through listings, signage and direct approaches
• conducting inspections and communicating with prospective tenants
• receiving expressions of interest or offers
• negotiating commercial terms up to an agreed limit
• preparing or arranging heads of agreement
• liaising with solicitors and property managers during the leasing process

What the agent should not have, unless you genuinely want it, is open-ended authority to bind you to final lease terms without approval. Many owners are happy for an agent to negotiate, but not to make final commitments about incentives, rent-free periods, make good obligations or landlord works.

Why the document matters commercially

The main risk is that you can end up paying commission in situations you did not expect. For example, an authority may say commission is payable if a tenant introduced during the agency period signs a lease months later, even if negotiations stalled and you completed the deal yourself.

Another issue is exclusivity. If you appoint an agent on an exclusive basis, you may still owe commission even if you find the tenant through your own network. That can make sense where the agent is spending real time and money on the campaign, but only if the term, fee structure and termination rights are reasonable.

There can also be regulatory issues. Real estate and property agency activity is regulated at state and territory level, so the exact formalities for authority documents, commissions and agent conduct may vary depending on where the premises are located. The commercial deal still matters, but the form of the authority and what is enforceable can depend on the local rules.

Who should be named as the client?

The named client should match the legal entity that owns or controls the right to lease the premises. This sounds simple, but it often gets muddled where property is held by a trustee, a related company, or multiple co-owners.

Before you sign, confirm:

• the correct legal owner or lessor is named
• the signatory has authority to sign for that entity
• any trust capacity is described accurately
• all owners who need to appoint the agent have signed

If the wrong entity signs, disputes can arise about whether the agent was properly appointed and who is liable for commission.

Legal Issues To Check Before You Sign

Before you sign a leasing authority agreement, the key legal question is whether the document reflects the deal you actually want with the agent, not just the deal in the standard form. This is where founders and property owners often get caught, especially when the leasing campaign needs to move quickly.

1. Type of appointment

The first thing to check is whether the authority is exclusive, sole or non-exclusive, because that changes when commission is payable.

• Exclusive authority: the agent has exclusive rights for the stated period, and commission may be payable even if you secure the tenant yourself.
• Sole agency: similar to exclusive, but the wording may differ on owner-introduced tenants, so the clause needs careful review.
• Non-exclusive authority: you may appoint multiple agents, but you need clear drafting on who earns commission if more than one agent is involved.

If the agreement uses those labels but the payment clause tells a different story, the payment clause usually becomes the real issue. Do not assume the heading alone will protect you.

2. Scope of authority and approval limits

The agent's authority should be broad enough to do the job, but narrow enough that major commercial calls still come back to you. Before you rely on a verbal promise that “we'll always check first”, look at the drafting.

Set clear approval points for matters such as:

• rent and rent review structure
• lease term and options
• incentives, including rent-free periods and fitout contributions
• landlord works and make good positions
• exclusivity rights for retail or shopping centre tenants
• agreement for lease or heads of agreement terms

If the agreement is silent, there is more room for misunderstanding about what the agent was authorised to promise.

3. Commission and when it is earned

Commission disputes usually turn on timing and wording. The agreement should say exactly when the agent earns commission and when you must pay it.

Key issues include:

• whether commission is triggered on signing heads of agreement, signing the lease, commencement of the lease, or payment of the first rent instalment
• whether GST is included or added on top
• how commission is calculated if the tenant exercises an option later
• whether commission applies to renewals, assignments or variations
• whether a reduced commission applies if the premises are leased on different terms from those originally marketed

Watch out for “effective cause” style clauses and broad introduction wording. Some agreements try to capture any tenant the agent had contact with, even if that contact was brief.

4. Tail period after termination

A tail period is the period after the authority ends during which the agent may still claim commission if a lease is later done with a tenant they introduced. Tail periods are common, but they need to be proportionate and precise.

A fair clause should deal with:

• the length of the tail period
• how introduced parties are identified, ideally in writing
• whether the tenant must have been an active prospect rather than a historic enquiry
• whether commission still applies if another agent later does most of the work

This is especially important if you are changing agents or pausing a campaign before you spend money on setup, signage or a relaunch.

5. Marketing expenses

Marketing costs can quietly expand if the agreement gives the agent broad discretion to incur expenses. The better approach is to state a campaign budget and require approval above that amount.

Check:

• what advertising is included in the base service
• which costs are reimbursable
• whether third party invoices will be provided
• whether marketing costs are refundable if no lease is secured
• who owns campaign materials and listing content

If the property is part of a larger branded business, also think about approval rights over how the premises and business name are presented in marketing.

6. Termination rights

You should be able to end the relationship if the agent is not performing or if your leasing strategy changes. A one-sided termination clause can leave you stuck paying for a non-performing appointment.

Look for:

• a clear end date, rather than an open-ended rolling authority
• termination for breach
• termination on notice without cause after a minimum campaign period
• what happens to outstanding marketing costs and introduced prospects after termination

Where there is a long authority period, ask whether it really matches the property and the current market. A specialist industrial property may justify a different approach from a suburban retail tenancy.

7. Liability, indemnities and misleading statements

The agent should take responsibility for its own conduct, but many standard forms shift risk back to the owner. That can become a problem if the agent makes inaccurate statements to prospective tenants.

Review any clause dealing with:

• indemnities in favour of the agent
• limits on the agent's liability
• your responsibility for information supplied about the premises
• compliance with Australian Consumer Law and fair dealing obligations

You will usually be responsible for the accuracy of information you provide, such as floor area, outgoings or permitted use details. The agent should still be required to avoid misleading statements and to refer uncertain issues back to you.

8. Landlord consent, title and leasing constraints

If you are not the freehold owner, do not assume you can appoint an agent and deal freely with the premises. Before you sign, check whether you need landlord, mortgagee or co-owner consent.

This can arise where:

• you are a head tenant proposing a sublease
• the premises are jointly owned
• the property is held in a trust with signing restrictions
• there is financier involvement affecting lease approvals

The authority should not promise a leasing outcome you may not legally be able to deliver.

Common Mistakes With Leasing Authority Agreement

The most common mistakes are not technical drafting errors. They are commercial assumptions that creep into the legal document and later turn into fee disputes or strained negotiations.

Signing the standard form unchanged

A standard authority is built to suit the agent's process, not your property. This is where landlords often accept a long exclusive term, broad tail period and uncapped marketing budget simply because the document arrived with a request to sign quickly.

Even a short contract review can identify the clauses worth negotiating. In many cases, a few targeted changes matter more than rewriting the entire agreement.

Leaving commission triggers vague

If the agreement says commission is payable when the agent “introduces” a tenant, you need to know what counts as an introduction. Does an email enquiry count? Does a property inspection count? What if the tenant already knew the premises?

Vague drafting creates arguments after the lease is done, when everyone is less motivated to compromise. Clear wording helps both sides.

Not controlling who can approve incentives

Agents often negotiate hard to secure a tenant, which is their role. The problem starts when incentives are discussed loosely and the owner assumes nothing is final until formal lease documents are signed.

If the authority allows the agent to negotiate without written limits, there is a risk that a prospective tenant believes certain concessions were approved. Even if that does not create a binding lease, it can derail negotiations and increase pressure on you to proceed on unwanted terms.

Ignoring state-based compliance rules

Commercial leasing is national, but agent regulation is not identical across Australia. Formal requirements about authorities, commissions and conduct can differ between states and territories.

If your business leases property in more than one jurisdiction, do not assume the same form works everywhere. The legal effect of a clause may shift depending on the location of the property and the regulatory framework applying to the agent.

Forgetting related documents

The authority agreement does not operate in isolation. It should line up with the broader leasing strategy and supporting documents.

Founders and SME owners should make sure it fits with:

• the proposed heads of agreement process
• your lease or sublease position
• any disclosure obligations relevant to retail leasing
• internal approval processes if the property is held by a company group or trust
• property management arrangements, if a separate manager is involved

Where these documents pull in different directions, the deal often slows down right when a tenant is ready to commit.

Relying on verbal understandings

If you were told the authority is “just a formality”, treat that as a warning sign. Before you sign a contract, any important point should appear in the written terms.

This includes promises about reduced commission, owner-approved spending, who handles tenant enquiries, and what happens if an existing contact signs later. If it is not written down, it is much harder to enforce.

FAQs

Is a leasing authority agreement the same as a commercial lease?

No. A leasing authority agreement is between you and the agent. A commercial lease is between the landlord and the tenant. The first governs the agency relationship, the second governs occupation of the premises.

Can I appoint more than one agent?

Yes, if the authority is non-exclusive and the terms allow it. You need clear commission drafting so there is no dispute about which agent is entitled to payment if multiple agents speak with the same prospect.

Do I still pay commission if I find the tenant myself?

Sometimes, yes. If the authority is exclusive or the commission clause is broad, commission may still be payable even where you brought the tenant to the deal. The answer depends on the exact wording.

What if the tenant signs after the authority ends?

You may still owe commission if the agreement includes a tail period covering tenants introduced during the authority term. Check how long the tail lasts and how introduced prospects must be identified.

Can an agent agree lease terms without my approval?

They should only do so within the authority you have actually given them. The agreement should set clear limits and require your approval for major commercial terms such as incentives, landlord works and final heads of agreement.

Key Takeaways

• A leasing authority agreement controls the relationship between you and the leasing agent, not the lease with the tenant.
• The most important issues are exclusivity, scope of authority, commission triggers, tail periods, marketing costs and termination rights.
• Before you sign, make sure the correct owner or lessor entity is named and that the signatory has authority to bind that entity.
• Do not rely on verbal assurances about fees, approvals or tenant introductions. Put the real commercial deal into the written terms.
• State and territory rules can affect how agency authorities operate, so the document should suit the location of the property.
• A short legal review before you sign can reduce the risk of double commission, unexpected expenses and arguments about what the agent was allowed to promise.
