Personal and director guarantees on business loans in Australia: what you are really signing
How personal and director guarantees work on Australian business loans, all-monies vs limited guarantees, Banking Code protections, key cases and how to reduce your exposure.
A personal guarantee makes you personally liable for a business's debt if the business does not pay. In Australia, almost every small business loan to a company or trust requires guarantees from the directors, and lenders sometimes ask for guarantees from spouses or parents too. The most important detail is the scope: an "all monies" guarantee can cover every present and future debt the business owes that lender, plus interest and enforcement costs, while a limited guarantee caps your liability at a stated amount. Read the guarantee, try to limit it, and get independent legal advice before signing.
This guide is part of business loan mistakes to avoid. It is general information, not legal advice.
How a guarantee works
- The lender lends to the business (company, trust or partnership).
- You promise that if the business defaults, you will pay.
- If the business defaults, the lender can demand payment from you, often without first exhausting its remedies against the business, depending on the wording.
- If you cannot pay, the lender can sue you and, if you have property, may rely on any mortgage you also gave. Ultimately an unpaid judgment can lead to bankruptcy proceedings.
Many guarantees are combined with an indemnity, which makes you liable even if the main loan turns out to be unenforceable against the business. Guarantees often continue until the lender releases you in writing, even after you leave the business.
All-monies vs limited guarantees: worked example
A building company has three facilities with one bank (illustrative):
- Term loan: $150,000
- Overdraft: $50,000 limit, fully drawn
- Equipment finance: $50,000
The director signed an all-monies, unlimited guarantee when the term loan was set up. Two years later the company fails, owing $250,000 to the bank, plus $12,000 of default interest and $8,000 of enforcement costs.
| Guarantee type | Director's potential liability |
|---|---|
| All monies, unlimited | Up to $270,000 (all three facilities, interest and costs) |
| Limited to $100,000 | Up to $100,000 (the cap; check whether interest and costs are included in or added to it) |
| Limited to the term loan only | The term loan balance plus related interest and costs |
The lender will first recover what it can from the company's assets and any security, so the director's actual payment is the shortfall, but the guarantee sets the ceiling.
Protections in the Banking Code of Practice
Banks that subscribe to the 2025 Banking Code of Practice have specific commitments to individual guarantors. In broad terms, the Code covers:
- giving prospective guarantors information about the loan and the borrower's financial position, including key documents;
- recommending independent legal and financial advice;
- a waiting period before the guarantee can be signed, and the right to withdraw before the credit is provided, in the circumstances the Code describes;
- the ability to limit the guarantee to an amount or to particular facilities, as the Code allows;
- providing information to guarantors on request during the life of the loan.
Check the Code's guarantee chapter for the exact obligations and exceptions. The Code also defines a sole director guarantor (a director of a company with only one director), and some protections apply differently to directors than to third-party guarantors. Non-bank lenders are not bound by the Banking Code.
What courts have said
Two High Court of Australia decisions shape how guarantees are judged:
- Commercial Bank of Australia Ltd v Amadio (1983): elderly parents with limited English guaranteed their son's company debts without understanding the risk. The Court set aside the guarantee as an unconscionable dealing because the bank took advantage of their special disadvantage.
- Garcia v National Australia Bank Ltd (1998): a wife's guarantee of her husband's business debts was set aside because she did not understand its effect, gained no benefit, and the bank had not explained it to her.
These cases do not mean guarantees are easy to escape. They show why lenders insist on independent legal advice certificates, and why you should take that advice seriously rather than treating it as paperwork.
How to reduce your exposure
- Limit the amount. Ask for a cap, ideally linked to one facility.
- Limit the facilities. Exclude future facilities unless you agree in writing.
- Avoid joint guarantees from non-involved family members. If one is required, they need their own independent lawyer.
- Ask for release conditions. For example, release once the loan falls below a set balance or the business meets certain ratios for two years.
- Get a release when you exit. If you sell your share or resign as director, get the lender's written release; resigning alone does not end a guarantee.
- Check insurance and structure. Your accountant may suggest structuring to keep certain assets separate, but such arrangements must be genuine; transfers made to defeat creditors can be reversed.
Checklist for guarantors
- Have I read the whole guarantee, including the indemnity?
- Which facilities does it cover, now and in future?
- Is there a maximum amount, and are interest and costs inside it?
- Have I seen the loan contract and the business's financial position?
- Have I had independent legal advice, from a lawyer who does not act for the lender or the borrower?
- Does my guarantee come with a mortgage over my home?
- What happens if I leave the business?
If a guarantee is called
- Get the demand and loan statements in writing.
- Get legal advice immediately; time limits in demands are short.
- Check whether the lender complied with the Code and the contract.
- Consider negotiating a settlement or payment plan.
- Contact a financial counsellor through the Small Business Debt Helpline.
- If you believe the guarantee was obtained unfairly, consider a complaint to the lender and then AFCA. See complaints and official sources.

A guarantee often sits alongside a GSA over the company; see the PPSR guide. Guarantees are commonly called after a covenant breach or default, covered in covenants, defaults and reviews.
Frequently asked questions
Can I refuse to give a personal guarantee?
Yes, but the lender may then decline the loan or offer it on different terms. For established businesses, it is sometimes possible to negotiate a limited guarantee or none.
Does a guarantee appear on my credit file?
The lender's enquiry may be recorded on your personal credit file. Defaults under a guarantee can also be reported.
Does resigning as director end my guarantee?
No. A guarantee continues until the lender releases you in writing.
Is a guarantee given by my spouse automatically invalid?
No. It may be challenged in limited circumstances, such as those in the Garcia case, but a properly explained guarantee with independent advice is generally enforceable.
