Personal Guarantees in Australian Business: Protect Yourself from Bad Debts

Australian business professionals reviewing a contract with personal guarantee clause before signing

Every year, thousands of Australian small businesses absorb losses from clients who cannot — or will not — pay. When the client is a company that subsequently goes into administration, many suppliers find themselves as unsecured creditors, waiting in line behind secured lenders with little hope of recovery.

A personal guarantee is one of the most effective — and underused — tools available to Australian businesses to protect against this scenario. Used correctly, it shifts the risk of non-payment from you to the person who controls the client's business. Used incorrectly, it can damage relationships and create its own legal headaches.

This guide explains what personal guarantees are, when to ask for them, how to implement them in Australia, and how to combine them with effective payment management to build a genuinely resilient accounts receivable process.

What Is a Personal Guarantee?

A personal guarantee is a legally binding commitment by an individual (typically a company director or owner) to personally repay a debt if the primary debtor (usually their company) fails to do so.

When you extend credit to a company, your legal claim is against that company. If the company has no assets or enters administration, you may recover little or nothing. A personal guarantee bypasses this by creating a secondary claim against the individual who signed it.

In practical terms: if ABC Constructions Pty Ltd owes you $25,000 and goes into liquidation, your unsecured claim against the company may be worthless. But if director John Smith signed a personal guarantee, you can pursue John Smith personally for the $25,000, regardless of what happens to the company.

When Should You Request a Personal Guarantee?

Personal guarantees are not necessary for every client relationship. Requesting one from a long-established client with an excellent payment history would likely cause offence without any practical benefit. The situations where they genuinely reduce risk include:

New Business Clients with No Track Record

A recently incorporated company has no credit history, no established reputation, and often limited assets. If you are extending significant credit to such a business, a personal guarantee from the director is a reasonable condition. It is common practice, and most legitimate business owners will understand why you ask.

Large or Unusual Orders

If a client places an order that is significantly larger than their usual volumes — or significantly larger than you would normally extend on credit — a personal guarantee (or at least a deposit) is sensible risk management.

Clients with Known Financial Difficulties

If you become aware that a client is under financial pressure — through industry gossip, ASIC searches, or your own AR data showing increasing debtor days — a personal guarantee on future orders is a proactive measure. Be aware, however, that demanding one from a client who is already in financial distress may not be practically enforceable if their personal situation is also compromised.

Sole Traders Incorporating

When a long-term sole trader client converts to a company structure, the legal entity you are dealing with changes. The new company has no credit history with you. Consider requesting a personal guarantee from the former sole trader/now director to maintain your protection.

Clients in High-Risk Industries

Construction, hospitality, retail, and certain parts of the events industry have historically high business failure rates in Australia. For clients in these sectors, personal guarantees are standard practice among trade suppliers and often expected.

How Personal Guarantees Work in Australian Law

In Australia, personal guarantees are governed primarily by the common law of contract, with additional protections and requirements under the Australian Consumer Law (ACL) and, where relevant, the National Credit Code.

Key Legal Requirements

For a personal guarantee to be enforceable in Australia:

Unconscionable Conduct and Consumer Protection

Australian courts and the ACCC take unconscionable conduct seriously. A guarantee obtained through pressure, without adequate disclosure, or where the guarantor clearly did not understand what they were signing may be set aside by a court. This is why the process around obtaining a guarantee is as important as the document itself.

Guaranteed Amount

Personal guarantees can be unlimited (covering all present and future debts) or capped at a specific amount. Unlimited guarantees are harder to obtain and more likely to face legal challenge. A capped guarantee — for example, covering up to $50,000 of outstanding credit — is often more practical and more readily agreed to by clients.

Important: Do not use a guarantee template downloaded from the internet without having it reviewed by an Australian solicitor. Guarantees that are improperly drafted can be entirely unenforceable. The cost of a legal review is trivial compared to the debt it might help you recover.

How to Request a Personal Guarantee Without Damaging the Relationship

The biggest hesitation most business owners have about requesting guarantees is the fear of appearing distrustful or losing the client. In practice, how you ask matters more than whether you ask.

Make It Part of Your Standard Process

The most effective approach is to make a personal guarantee a standard condition of your credit application, not a special request triggered by suspicion. When every new business client signs the same credit application that includes a guarantee clause, it feels procedural rather than personal.

Frame it this way: “Our standard credit application includes a director's guarantee — this is our normal process for all business accounts. It is a straightforward document and most clients are happy to sign it alongside the credit application.”

Be Transparent About Why You Ask

If a client pushes back, a simple honest explanation is better than a legalistic one: “We have had situations in the past where companies we worked with went into administration and we ended up as unsecured creditors. We use guarantees now as a standard protection for our business.” Most business owners understand this. If they are running a legitimate operation, they will usually comply.

A Client Who Refuses Has Told You Something

A client who flatly refuses to sign a guarantee when other comparable clients routinely do so has given you valuable information about their confidence in their own business. This is not an automatic reason to walk away from the relationship, but it is a reason to reduce your credit exposure — shorter payment terms, smaller credit limits, or deposits on large orders.

Tip: Many businesses find it easier to introduce guarantees as part of a broader credit policy review, framed as “we have updated our credit terms for all business accounts.” This avoids any implication that the request is specific to that client.

Building a Complete Bad Debt Protection Strategy

A personal guarantee is one tool in a larger strategy. On its own, it is a last resort. The businesses with the best AR outcomes combine multiple layers of protection:

Layer 1: Prevention

Layer 2: Early Detection

Layer 3: Consistent Follow-Up

Layer 4: Recovery

Alternatives and Complements to Personal Guarantees

Personal guarantees are not always practical or appropriate. Consider these alternatives in situations where a guarantee is not achievable:

Trade Credit Insurance

Trade credit insurance covers your accounts receivable if a client cannot pay due to insolvency or protracted default. It is particularly useful for businesses that deal with a small number of large clients where the failure of one could be catastrophic.

PPSR Registration

The Personal Property Securities Register (PPSR) allows you to register a security interest in goods you supply under a retention of title clause. This gives you priority over other unsecured creditors if the client becomes insolvent and still has your goods.

Deposit Requirements

Requiring a 25–50% deposit before commencing work reduces your exposure significantly. For high-risk clients or large one-off orders, a deposit removes much of the credit risk without requiring a formal guarantee.

Shorter Payment Terms

Reducing your payment terms from 30 days to 14 days for higher-risk clients reduces the maximum amount outstanding at any time. Combine shorter terms with automated reminders and you have a practical, relationship-neutral risk reduction strategy.

The Role of Consistent Follow-Up in Preventing Guarantee Enforcement

The best outcome with a personal guarantee is that you never need to enforce it. The way to achieve that is consistent, professional follow-up on overdue invoices before they escalate to a point where enforcement is necessary.

Most overdue invoices are not the result of clients deciding not to pay. They are the result of accounts payable queues, internal approval delays, cash flow timing, and simple oversight. A professional reminder sequence addresses all of these without any confrontation.

PaidMate automates this process through your Xero account, sending reminders at the right intervals in a tone that maintains the relationship. The tagline says it directly: get paid without burning bridges. A well-timed friendly reminder recovers far more revenue than an adversarial demand, and it costs less in time, stress, and relationship capital.

Reserve the personal guarantee for the situations where all else has failed — or as a deterrent that encourages clients to pay on time in the first place, knowing that their personal assets ultimately underwrite the debt.

Frequently Asked Questions

Is a personal guarantee enforceable if the guarantor claims they did not understand it?

Potentially not, which is why it is important that guarantors have the opportunity to obtain independent legal advice before signing. Document that this opportunity was offered. Courts have set aside guarantees where there is evidence of misrepresentation or where the guarantor demonstrably did not understand what they were signing.

Can I ask for a personal guarantee from a sole trader?

Sole traders are already personally liable for their business debts, so a formal guarantee adds little protection. The risk with sole traders is that their personal assets may be limited. A credit check, deposit, or trade credit insurance may be more useful in this case.

How do I enforce a personal guarantee in Australia?

Enforcement typically involves sending a formal demand letter to the guarantor, then commencing legal proceedings if payment is not made. For amounts under state small claims tribunal limits (generally $20,000–$100,000 depending on the state), tribunal proceedings can be initiated without a solicitor. For larger amounts, engage a commercial litigation solicitor.

Does a personal guarantee expire?

Not automatically. A guarantee remains in force until the debt is repaid, the guarantee is discharged, or it is found to be unenforceable. Some guarantees include expiry clauses — if yours does not, it may remain effective indefinitely for debts incurred during the guarantee period.

Can I request a guarantee after credit has already been extended?

Legally, there are complications with retroactive guarantees because consideration (the exchange of value) for the guarantee must exist. It is cleaner to require guarantees before or simultaneously with extending credit. Consult a solicitor if you are considering a retroactive arrangement.

What if the guarantor files for personal bankruptcy?

If the guarantor enters personal bankruptcy (formally called bankruptcy in Australia, not insolvency), you become a creditor of their estate. You may recover a portion of the debt, depending on the guarantor's assets. This is why a guarantee is most valuable when the guarantor has personal assets worth protecting — their home, investment properties, or savings.
