Understanding Guarantees in Commercial Agreements: What Australian Businesses Need To Know

Thinking of signing a business contract that asks for a guarantee? Unsure what that really means for you or your company? In this guide, we’ll explain guarantees in plain English, outline how they work in Australia, and share practical tips to reduce your risk before you sign anything.

Guarantees are common in leases, supply contracts, finance documents and more. They help the other party manage risk - but they can also expose your personal assets or the assets of a related company if things go wrong.

With the right information and a careful review, you can negotiate fairer terms and sign with confidence. Let’s walk through the essentials.

What Is a Guarantee in a Commercial Agreement?

A guarantee is a promise by one party (the guarantor) to be responsible for another party’s obligations if they don’t perform. In most business contracts, that means paying money, making good on losses or ensuring performance if the primary party defaults.

In practice, a guarantee is usually a clause within a broader agreement, or a short, separate document, that clearly sets out:

• Who the guarantor is (for example, a director or a related company),
• What obligations are being guaranteed (e.g. rent, invoices, performance), and
• When and how the guarantee can be enforced.

For example, a landlord may ask a director to personally guarantee a commercial lease. If the company doesn’t pay rent, the landlord can pursue the director under the guarantee.

If you’re wrapping your head around the concept and roles, it can help to read a plain English overview of guarantors and their obligations.

Is a Guarantee the Same as an Indemnity?

Not quite. A guarantee is a promise to step in if someone else fails. An indemnity is a direct promise to make the other party whole for loss, often regardless of whether a default has occurred. Many commercial contracts include both - that combination can significantly increase your risk, so it’s important to read those clauses carefully.

Do Guarantees Have To Be in Writing?

As a general rule in Australia, guarantees need to be in writing and signed by (or on behalf of) the guarantor to be enforceable, due to “Statute of Frauds” style rules that apply in several states and territories. There are nuances across jurisdictions and practical exceptions, so treat this as a baseline rather than a universal rule - either way, you should assume a written, signed guarantee will be enforceable if properly drafted.

Why Do Australian Commercial Contracts Include Guarantees?

Guarantees exist to manage risk for the party providing goods, services, premises or credit. You’ll most often see them where there’s meaningful exposure on the other side.

• Lending and credit: Banks and trade creditors want extra comfort they’ll be paid. A personal guarantee from a director, or a corporate guarantee from a parent entity, reduces their risk.
• Leases: Commercial landlords commonly ask for director guarantees to cover rent, outgoings and make-good costs.
• Supplies and logistics: Where suppliers offer credit terms or commit significant inventory, they may ask for a guarantee to backstop non-payment.
• New ventures: Startups and thinly capitalised companies may be asked for a guarantee because they have a limited track record or assets.

From your perspective, agreeing to a guarantee can unlock the deal - but it also shifts risk onto you or your related entity. The key is to understand the scope and negotiate sensible limits where possible.

How Do Guarantees Work in Practice?

In a typical scenario, your company signs a primary agreement (a lease, supply contract or loan) and the guarantor signs the guarantee contained in that agreement or a companion deed.

If the company defaults - for example, misses rent, doesn’t pay an invoice or breaches key terms - the other party can call on the guarantee. Depending on the drafting, you may be required to pay on demand, fix the breach, or cover losses arising from the default.

Common Types of Guarantees

• Personal guarantees: An individual (often a director) guarantees the company’s obligations. This can expose the guarantor’s personal assets. Before signing, it’s worth revisiting the risks in personal guarantees.
• Corporate guarantees: A related entity - for example, a parent company - guarantees the obligations of a subsidiary or operating entity. This can spread risk across a group.
• Bank guarantees: A bank promises to pay the beneficiary (e.g. a landlord) on your instruction or on demand, up to a stated amount. You provide cash collateral or a facility to the bank.
• Limited vs unlimited: A limited guarantee caps the guarantor’s exposure (e.g. to a dollar amount or specific obligations). An unlimited guarantee can cover all present and future amounts.
• Continuing guarantees: These remain in place for a class of obligations (for example, a rolling trade credit account) until revoked in writing and accepted by the creditor.

Security Interests Alongside Guarantees

Sometimes the other party wants both a guarantee and security over assets. For example, they might request a General Security Agreement (GSA) over the company’s personal property (equipment, receivables, etc.). A GSA can be registered on the Personal Property Securities Register (PPSR), which strengthens the creditor’s priority position if things go wrong.

If you’re asked to sign a GSA with a guarantee, you’ll want to understand the broader effect of a General Security Agreement and exactly which assets are being captured.

Enforceability and Variations

Well-drafted guarantees are usually enforceable if properly executed. Many include wording that keeps the guarantee alive even if the primary agreement is varied, extended or assigned. That’s why a “continuing guarantee” or “no release on variation” clause matters - it can extend your exposure beyond what you expected.

What Should You Check Before You Sign (and Common Pitfalls)?

It’s tempting to sign quickly to secure a deal, but guarantees deserve extra attention. Here’s a focused checklist to work through.

Scope and Limits

• Liabilities covered: Is it limited to a specific contract and amount, or does it capture “all present and future liabilities” to that party?
• Types of obligations: Are you guaranteeing payment only, or also performance, indemnities, interest, costs and damages?
• Cap and sunsets: Can you set a dollar cap or a time limit (for example, 6–12 months after termination)?

Duration and Exit

• When does it end? Does it automatically terminate when the contract ends, or is written release required?
• Transfer or sale: If you sell your shares or resign as a director, can you be released on completion? Build that pathway in now - it’s much harder later.

Multiple Guarantors

• Joint and several liability: If there are multiple guarantors, the beneficiary can usually pursue any one of you for the full amount. Understand this risk allocation before you sign.

Execution and Formalities

• Signing correctly: Some guarantees are deeds and have stricter execution requirements. Cross-check against your company’s execution rules, including how section 127 execution works and the general legal requirements for signing documents in Australia.
• Board approval: If a company is giving a corporate guarantee, ensure there’s a proper directors’ resolution recorded.

Fairness and Conduct

• Clear, accurate information: While there’s no general legal “duty to disclose everything,” the other party must not mislead you. Misleading or deceptive conduct is prohibited under the Australian Consumer Law (see section 18), and unfair contract term rules also apply in many small business contexts.
• Independent advice: For personal guarantees in particular, getting advice helps ensure you understand the risks and reduces later disputes about capacity or understanding.

Common Pitfalls To Avoid

• Signing an “all moneys” guarantee when a capped amount would do.
• Overlooking a continuing guarantee that survives variations and renewals.
• Assuming the guarantee ends when you exit the business - if there’s no written release, you may still be on the hook.
• Missing execution formalities on a deed, which can create uncertainty (or sometimes unintended enforceability).

Reducing Risk: Practical Ways To Limit or Manage Liability

You can often negotiate a more balanced position. Here are practical levers to consider.

Negotiate the Shape of the Guarantee

• Cap it: Propose a hard dollar cap or a cap linked to a number of months of exposure (e.g. three months’ rent).
• Limit the scope: Restrict it to payment obligations under a specific contract or purchase order, rather than “all present and future liabilities.”
• Timebox your exposure: Include a sunset clause that ends the guarantee a defined period after termination or expiry.
• Add release triggers: Build in a release on sale of the business, novation to a new entity that meets credit criteria, or replacement security (e.g. a bank guarantee).

Trade a Guarantee for Other Security

• Higher bond or deposit: For leases or supply arrangements, a larger bond is often more palatable than a personal guarantee.
• Bank guarantee: Consider offering a bank guarantee instead of a personal guarantee, which avoids exposing personal assets.
• Security over assets (carefully scoped): If the other party requires a GSA, limit the collateral and clarify registration on the PPSR to avoid unintended encumbrances.

Tighten the Primary Contract

• Clear default and cure periods: Build in notice and cure periods so you can fix issues before a guarantee is called.
• Reasonable fees and interest: Limit default interest, indemnities and costs that would inflate your guarantee exposure.
• Assignment and variation controls: Prevent the other party assigning the contract (and guarantee) without consent, or include a release on any assignment.

Keep Good Housekeeping

• Store signed copies of guarantees and related contracts in one place, with a summary of key terms (cap, term, release conditions).
• Diary review dates and renewal triggers so you can revisit or renegotiate guarantees ahead of time.
• If you intend to exit the business or restructure, plan the release process early - make it a condition of completion.

Get the Right Support

A short, targeted contract review can pay for itself by spotting red flags and suggesting workable alternatives. If you’re being asked to sign a personal or corporate guarantee, consider a focussed review of the guarantee wording, the primary contract and any related security (for example, a GSA or PPSR registration).

Key Takeaways

• A guarantee is a legal promise to cover another party’s obligations if they default - it’s common in leases, loans and supply contracts, but it can expose personal or corporate assets.
• Check the scope, cap and duration. Look for continuing or “all moneys” wording, joint and several liability, variation clauses and how (and when) you can be released.
• Execution matters. Many guarantees are deeds, so ensure they’re signed properly in line with section 127 and general document signing rules.
• Security often goes hand-in-hand with guarantees. If a General Security Agreement is requested, understand PPSR registration and which assets are affected.
• You can usually negotiate: propose caps, time limits, cure periods, alternative security (like bank guarantees) and clear release mechanisms on exit.
• If you’re unsure, get independent advice before signing - a brief review can reduce risk and help you secure a fairer position.
