What Is A Guarantee In Australia?

Extending credit, signing a new lease or taking on a big customer can be great for growth - but it also adds risk. That’s where guarantees come in.

If you’ve been asked to “sign a guarantee” or you’re thinking about requesting one from a customer or supplier, it’s smart to understand exactly what a guarantee is, how it works in Australia, and how to use it fairly and effectively.

In this guide, we break down the key points in plain English, so you can protect your cash flow without overexposing your business (or yourself) to unnecessary liability.

What Is A Guarantee In Business Contracts?

A guarantee is a promise by one party (the guarantor) to be responsible for another party’s obligations if they don’t meet them. It’s a common risk management tool in business-to-business deals, especially where you’re giving credit or taking on performance risk.

Here’s the basic setup:

• The principal (your customer, tenant or contractor) owes obligations under a contract - e.g. to pay invoices or complete work.
• The guarantor promises that if the principal defaults, the guarantor will step in - usually to pay the debt or remedy the breach.
• You (as the beneficiary) can enforce the guarantee if the principal fails to perform.

In Australia, guarantees are often paired with an indemnity. An indemnity is a separate promise to compensate you for loss regardless of the principal’s liability (for example, losses you suffer because you chased a debt). Many documents are titled “Guarantee and Indemnity” because they include both promises.

Because a guarantee is typically executed as a deed and can create personal liability, it’s important to use clear, fair terms and follow correct signing requirements.

Common Types Of Guarantees In Australia

Guarantees aren’t one-size-fits-all. As a small business, you’ll most often see these types:

• Director or Personal Guarantees - A company’s directors (or owners) personally promise to cover the company’s debts or obligations if the company can’t. These are common when you offer trade credit or enter a lease. Learn more about the risks and protections around Personal Guarantees.
• Bank Guarantees - A bank issues a payment undertaking on behalf of your customer (the applicant), promising to pay you on demand if certain conditions are met. These are widely used in commercial leasing and construction to secure performance or rent. See our guide to Bank Guarantees.
• Parent Company Guarantees - A parent company guarantees the obligations of its subsidiary. Useful when dealing with a newly formed or thinly capitalised operating entity.
• Performance Guarantees - These secure non-payment obligations (e.g. timely completion of works). They’re common in construction and supply contracts.
• Continuing Guarantees - These cover a series of transactions (for example, ongoing trade credit) rather than a single contract, often until revoked in writing and satisfied.

Sometimes you’ll also take a security interest (for example, over equipment or receivables) alongside a guarantee. A General Security Agreement (GSA) plus a properly registered PPSR interest can materially improve your position if there’s a default.

When Should Your Small Business Ask For A Guarantee?

Not every deal needs a guarantee. But in higher-risk situations, asking for one can be the difference between writing off a loss and getting paid.

Consider a guarantee when:

• You’re extending trade credit - If you’re supplying goods or services on 14-60 day terms, a director guarantee (and retention of title) strengthens your position.
• You’re granting exclusive rights or investing upfront - Distribution, reseller, or franchise arrangements often justify guarantees because you invest time, stock or territory value before revenue flows.
• The counterparty is newly incorporated or thinly capitalised - A parent or director guarantee can backstop obligations until the business builds a track record.
• You’re leasing commercial premises or equipment - Landlords and equipment financiers frequently require guarantees or bank guarantees to secure rent and make-good.
• Project delivery risk is high - In construction or complex services, performance guarantees (or bank guarantees) provide comfort that milestones will be met - or you’ll have recourse if they’re not.

Asking for a guarantee shouldn’t be confrontational. Frame it as standard risk management for both sides and be willing to calibrate the scope (for example, capping the amount or limiting the term) so the arrangement is fair.

What Are The Risks If You Give A Guarantee?

Before you sign a guarantee as a director, owner or related entity, get clear on what you’re promising. The risks can be significant and often personal.

• Personal exposure - A director or personal guarantee can put your own assets on the line if the company defaults.
• “Joint and several” liability - Many guarantees say each guarantor is liable for the whole debt, not just a share. That means the beneficiary can pursue any guarantor for the full amount.
• Unlimited amount - Unless it’s capped, a guarantee can cover all present and future obligations. If you intend a cap, make sure it’s clearly stated.
• Continuing obligations - Some guarantees keep rolling even after the initial contract ends, unless you revoke them and the debt is repaid.
• Demand risk - For bank guarantees, payment can be triggered “on demand” if wording allows it, even while disputes are ongoing (subject to fraud exceptions).
• Security and enforcement - If you also give security (e.g. a GSA or mortgage), the beneficiary may take possession or appoint a receiver after default.
• Contract terms can multiply liability - Broad indemnities, cross-default clauses, or aggressive interest and costs provisions can escalate exposure quickly. Balance these with sensible limitation of liability and dispute terms where you can.

If you’re unsure, ask for the document in advance, read it carefully, and consider legal advice before signing. Small tweaks (like a dollar cap, time limit or carve-outs for indirect loss) can dramatically change your risk profile.

How Do You Draft And Use Guarantees Properly?

Using guarantees well is about clarity, fairness and compliance. Here’s a practical approach.

1) Decide What You’re Securing

Start with the risk you actually need to cover:

• Payment risk for goods or services on credit.
• Performance risk for projects or service levels.
• Lease obligations (rent, outgoings, make-good).

Your risk profile guides the right instrument and scope.

2) Choose The Right Instrument

• Guarantee and Indemnity - A standard, flexible document suitable for trade credit, supply and services. If you need a tailored Deed of Guarantee and Indemnity, it’s best drafted to match your terms of trade and credit process.
• Bank Guarantee - Favoured for leases and construction because it ties up the applicant’s banking facility rather than personal assets, and you hold a bank’s undertaking.
• Security Interest (with or without a guarantee) - A General Security Agreement over all assets or a specific asset (e.g. ROT over inventory) can be registered to strengthen priority if there’s insolvency.

3) Define Clear, Proportionate Terms

Keep the guarantee tight and practical:

• Scope - Identify the principal obligations being guaranteed (e.g. payment under Contract X dated Y).
• Cap and duration - Consider a dollar cap and time limit (for example, “up to $50,000 for obligations that arise in the first 12 months”).
• Conditions precedent - Require steps like providing financial statements or identification before the guarantee takes effect.
• Triggers - State when you can claim (missed payment, insolvency, repudiation) and what evidence is needed.
• Multiple guarantors - If there are two or more, clarify if liability is joint and several, and allow you to release one without releasing others.
• Release - Specify when and how the guarantee ends (e.g. after full payment and 90 days without dispute).

4) Execute It Correctly

In Australia, guarantees are often signed as deeds. This can affect enforceability requirements, so make sure execution is correct for companies and individuals.

• Company execution - Companies can sign under section 127 of the Corporations Act (e.g. two directors, a director and company secretary, or a sole director/secretary where applicable).
• Electronic signing - Electronic execution is generally recognised if done properly; know when wet-ink or electronic signatures are appropriate, and keep good records.
• Witnessing - Some deeds require witnessing for individuals. Follow the deed’s formalities closely.

5) Secure And Perfect Your Interest

If you are taking a security interest as part of the arrangement (for example, ROT over goods or a GSA), register it on the PPSR promptly to preserve priority. Unregistered security interests can be lost if the other side becomes insolvent.

6) Check For Compliance Issues

Two quick compliance checks can save headaches:

• Unfair contract terms - The Australian Consumer Law’s unfair contract terms regime applies to many standard form contracts with small businesses. Clauses that go beyond what’s reasonably necessary could be unenforceable (and attract penalties). Keep guarantee terms proportionate to the risk.
• Privacy and data - If you collect personal information from a guarantor (e.g. ID checks), ensure your Privacy Policy and consent processes are in order.

Alternatives And Complements To Guarantees

Guarantees are powerful, but they’re not the only way to manage risk. Depending on the deal, you might combine or substitute with:

• Deposits and progress payments - Reduce exposure by getting paid upfront or at milestones.
• Retention of title and PPSR registration - Keep title to goods until paid, and register a security interest early.
• Credit limits and reviews - Start with a lower credit limit and increase only after a solid payment history.
• Bank Guarantees - Particularly for leases and build contracts where you prefer a bank’s undertaking over a personal promise.
• Set-off and suspension rights - Clear set-off clauses and service suspension terms can protect cash flow if invoices go unpaid.
• Cap your own liability - If you’re being asked to give a guarantee (or broader contractual promises), negotiate sensible caps and exclusions alongside the guarantee to balance risk.
• Insurance - Trade credit insurance or professional indemnity may complement your contractual protections.

The right mix depends on the size of the deal, the counterparty’s strength, and how critical the relationship is. The goal is to keep things fair while protecting your downside.

Practical Tips For Requesting Or Giving A Guarantee

Whether you’re asking for a guarantee or deciding if you should give one, these tips help you move forward with confidence:

• Be transparent - Explain why a guarantee is needed and what would remove the need in future (e.g. 6 months of on-time payments).
• Tailor the scope - Use caps, time limits and clear triggers to match the guarantee to the true risk.
• Bundle with sensible credit terms - Pair the guarantee with practical terms: late fees, suspension rights, ROT and PPSR registration.
• Keep clean records - Store signed copies, notices and payment history. If you ever need to enforce, good records are critical.
• Review annually - As relationships mature, consider reducing or releasing guarantees to maintain goodwill.
• Get it drafted properly - A short, plain-English guarantee that’s legally robust is better than a long, unclear one. Where possible, align the wording to your customer contract.

Key Takeaways

• A guarantee is a promise by a third party to step in if your customer or contractor doesn’t perform - commonly used to secure payment and performance in Australian business contracts.
• Common forms include director or personal guarantees, bank guarantees, and parent company guarantees; each comes with different risk and enforcement mechanics.
• If you request a guarantee, match the scope to the risk with clear caps, time limits and triggers, and consider registering security on the PPSR where relevant.
• If you’re asked to give a guarantee, understand the personal exposure, watch for joint and several liability, and negotiate proportionate terms.
• Execute guarantees correctly (including deed formalities and company signing under section 127) to avoid enforceability issues.
• Alternatives like deposits, security interests, bank guarantees and sensible set-off or limitation of liability clauses can complement or replace guarantees depending on the deal.
