Personal Guarantee Risks | Sprintlaw Australia

If you’re running (or about to start) a small business, there’s a good chance you’ll be asked to sign something that feels “pretty standard” when you apply for finance, lease premises, or set up trade credit with a supplier.

Often, that “standard” document includes a clause making you a personal guarantor.

A personal guarantee can help your business secure funding or contracts that might otherwise be out of reach. But it can also quietly shift business risk onto you personally - even if you operate through a company structure.

In this guide, we’ll break down what a personal guarantor is, what it really means for your legal obligations, the risks to watch for, and practical alternatives you can try to negotiate as an Australian small business owner.

What Is A Personal Guarantor (And When Might You Be Asked For One)?

A personal guarantor is a person who promises to pay (or otherwise perform) if another party doesn’t meet their obligations under an agreement.

In small business, the “other party” is usually your business - for example, your company, trust, or partnership. The personal guarantor is often a director, founder, or business owner.

Put simply: if the business can’t pay, you may be legally required to pay.

Common Situations Where Personal Guarantees Come Up

You might be asked to sign as a personal guarantor when you’re dealing with:

Business loans and overdrafts (including refinancing, increased limits, or equipment finance)
Commercial leases (especially if your business is new or has limited trading history)
Supplier credit accounts (e.g. “30-day terms” accounts for stock, materials or services)
Franchise or distribution arrangements (where ongoing fees and compliance costs can be significant)
Service contracts that involve ongoing minimum payments or termination fees

It can feel like “everyone signs these”. And in many industries, personal guarantees are very common - but that doesn’t mean they’re risk-free, or that the wording will be reasonable.

How A Personal Guarantee Differs From A Company’s Liability

One of the biggest misunderstandings we see is: “I have a company, so I’m protected.”

A company generally has limited liability, meaning the company is responsible for its own debts (not you personally). But a personal guarantee can override that practical protection by creating a separate promise from you to the creditor.

So even if your business trades through a company, the personal guarantor clause can put your personal assets on the line.

What Legal Obligations Do You Take On As A Personal Guarantor?

When you sign a personal guarantee, you’re entering into a legal contract. The exact obligations depend on the wording, but personal guarantees in Australia often go further than most people expect.

It’s Not Just “If The Business Can’t Pay”

Many guarantees are drafted so that the creditor can pursue the guarantor:

as soon as there is a default (even if the creditor hasn’t exhausted options against the business), and/or
without needing to prove the business is insolvent, and/or
for additional amounts and costs allowed under the document (for example, interest and recovery costs).

Some guarantees are also drafted as an indemnity (or include an indemnity). In plain English, an indemnity can make it easier for the creditor to claim against you, and it may broaden what you’re responsible for, depending on the drafting.

Joint And Several Liability (If More Than One Person Signs)

If multiple directors or owners sign as personal guarantors, the guarantee often states you are “jointly and severally liable”.

This means the creditor may be able to pursue any one guarantor for the entire debt - not just “your share”.

Even if you later sort things out between yourselves, the immediate exposure can be significant.

Guarantees Can Keep Operating Even If The Deal Changes

Another common issue is guarantees that keep operating even if:

the creditor extends more credit later
the terms are varied (e.g. interest rate changes, payment plan changes)
the business changes structure (e.g. you move from sole trader to company)
a director resigns (but the guarantee doesn’t automatically end)

That’s why it’s important to understand whether it’s a one-off guarantee (tied to a specific contract) or an ongoing “all monies” guarantee (covering all present and future amounts owed).

Key Risks For Small Business Owners Who Sign As A Personal Guarantor

Personal guarantees aren’t automatically “bad” - sometimes they’re the price of entry when you’re growing. But you should go in with clear eyes about what can happen if things go wrong.

1. Personal Assets Can Be Exposed

If your business defaults and you are liable as a personal guarantor, the creditor may pursue you personally. Depending on your situation, that can put pressure on personal assets and finances.

This is one reason guarantees feel confronting: they can turn a business problem into a personal financial problem.

2. You May Be Liable For More Than The Original Amount

Guarantees often cover more than the invoice total or loan principal. They can include:

interest
recovery/enforcement costs (including legal fees)
administration costs
other amounts the contract says you must pay, depending on how it’s drafted

This can make the final amount much larger than you expected.

3. You Might Lose Negotiating Power When You Need It Most

If the contract is already signed and the business runs into trouble, you’re often negotiating from a weaker position.

That’s why the best time to reduce the risk is before you sign - when the creditor still wants your business and you can propose alternatives or limits.

4. Director Duties And Personal Guarantees Can Collide

If you’re a director of a company, you also have obligations about how the company is managed, particularly around solvency and incurring debts.

A personal guarantee can add a second layer of risk: not only is the company responsible for debts, you may be personally on the hook too. If you’re unsure how a guarantee interacts with your role, it’s worth getting advice early (especially before the business takes on significant commitments).

What Should You Check Before You Sign A Personal Guarantee?

Personal guarantees are often buried in application forms, supply agreements, lease documents, or “terms and conditions” attachments. It’s easy to miss them if you’re moving quickly.

Before signing as a personal guarantor, it helps to slow down and check a few key items.

Is It An “All Monies” Guarantee?

An “all monies” (or “all obligations”) guarantee can cover all amounts the business owes now and in the future - sometimes across multiple arrangements.

If you’re expecting to guarantee a single contract, try to ensure the guarantee is limited to that specific agreement and that specific amount.

Is There An Indemnity Clause?

Guarantees commonly include indemnities. This can increase your exposure and make it easier for the creditor to claim.

If the document includes both a guarantee and an indemnity, you should be especially careful.

Are There Limits On The Amount And Time Period?

In negotiations, look for:

Monetary cap (e.g. “up to $50,000”)
Time limit (e.g. ends after 12 months or after a specific delivery/project)
Trigger limit (e.g. guarantee only applies if the business fails to pay within a set number of days)

Without these, the guarantee may be far broader than you intend.

Does The Guarantee Survive If You Exit The Business?

If you’re planning to bring on investors, co-founders, or you think you might sell the business later, it’s important to understand how (and whether) you can be released as guarantor.

This often requires the creditor’s written release - it’s not automatic.

Is The Contract Actually Clear About What You’re Guaranteeing?

If the main agreement is unclear (for example, the payment terms, deliverables, or termination rights), your risk as a personal guarantor is harder to measure.

This is where a proper contract review can be valuable. The goal isn’t just to understand the guarantee clause - it’s to understand the whole deal you’re standing behind.

Alternatives To A Personal Guarantor (And What You Can Try To Negotiate)

If a supplier, landlord, or lender asks for a personal guarantor, it doesn’t always mean the terms are non-negotiable.

Your bargaining power depends on your industry, trading history, and the size of the deal - but many small businesses can negotiate a more balanced position than they expect.

Option 1: Offer A Smaller Guarantee With A Cap

A capped guarantee can be a practical compromise where the other side wants comfort, but you want certainty.

For example, rather than guaranteeing “all amounts owing”, you might agree to a cap linked to:

one or two months of supply,
a specific piece of equipment, or
a fixed portion of the lease obligations.

Option 2: Provide A Security Deposit Or Higher Upfront Payment

Sometimes you can reduce (or avoid) a personal guarantee by offering:

a higher security deposit
partial prepayment
shorter payment terms (e.g. 7 days instead of 30 days)

This can be attractive to the other side because it reduces their risk without tying your personal finances to the contract long-term.

Option 3: Consider Security Arrangements Like A PPSR Registration (Where It Fits)

In some supplier and asset finance arrangements, the real concern is: “If you don’t pay, can we recover the goods?”

In those cases, the creditor may protect itself by taking security and registering a security interest on the Personal Property Securities Register (PPSR) - sometimes alongside, and sometimes instead of, a personal guarantee depending on the bargaining position and the deal.

If you want to understand how those registrations work in practice, PPSR concepts are worth knowing - especially if you buy or sell equipment or stock on credit.

From the business owner’s side, it can also be useful to do a PPSR check when you’re purchasing second-hand assets or taking over a business, so you’re not surprised by existing security interests.

Option 4: Negotiate A More Limited Form Of Security

Depending on the deal, you may be able to negotiate a different risk-control mechanism, such as:

stepped credit limits that increase only after good payment history
shorter contract terms with renewal options
clear termination rights so you can exit if it’s not working

These changes won’t always remove the guarantee, but they can reduce how likely it is you’ll ever face a claim.

Option 5: Review Your Business Structure And Internal Documents

Sometimes you’re asked for a personal guarantor because the other party is nervous about enforcement - especially when the business is new.

Having your internal setup clearly documented won’t always remove the request, but it can help you negotiate and operate with fewer surprises. Depending on your situation, that might include:

a Company Constitution (particularly for companies with more than one decision-maker)
a Shareholders Agreement to set expectations between founders and reduce internal disputes that can derail repayments

And if you are taking on a finance arrangement that involves secured assets, it’s helpful to understand how a general security agreement works, because it can affect what the lender can claim over if the business defaults.

Key Takeaways

A personal guarantor is a person who legally promises to meet a business’s obligations if the business doesn’t, which can expose you personally even if you trade through a company.
Personal guarantees can be broader than expected, including “all monies” obligations, indemnities, and liability for interest and recovery/enforcement costs (depending on the drafting).
Before signing, check key points like caps, time limits, whether it survives changes to the deal, and whether multiple guarantors are jointly and severally liable.
Alternatives may be available, such as capped guarantees, higher deposits or upfront payment, stepped credit limits, or security arrangements (including PPSR registrations) depending on the contract and bargaining position.
Getting the contract terms right upfront is usually far easier than trying to renegotiate after the business is under pressure.
