Director's guarantee on a business loan: what it means for you

A director’s guarantee on a business loan is a personal promise by a company director to repay the company’s debt if the company can’t. Normally a company’s debts belong to the company alone. Signing a guarantee removes that separation for the loan it covers, so the lender can come after you personally, and potentially your home, if the business defaults. It’s one of the most important documents you’ll ever sign as a director, and one of the least read.

Guarantees are standard in Australian business lending, particularly for unsecured loans. Understanding exactly what you’re signing, and what you can negotiate, is the difference between a manageable risk and an open-ended one.

What does a director’s guarantee actually cover?

The scope depends entirely on the wording. Look for these elements:

Element	Narrow guarantee	Broad guarantee
Which debts	One named loan	All present and future debts to the lender (“all moneys”)
How much	Capped at a stated dollar amount	Unlimited, including costs and enforcement charges
How long	Ends when that loan is repaid	Continues until formally released
Security attached	None, or a specific property	Mortgage over the guarantor’s home
Who signs	Directors only	Directors, shareholders, sometimes spouses

An “all moneys” guarantee is the one to watch. It can cover a future overdraft, equipment lease or credit card the company takes from the same lender years later, long after you’ve forgotten signing anything.

Personal guarantee vs director’s guarantee: is there a difference?

They’re the same thing seen from different angles. A personal guarantee is any guarantee given by an individual. A director’s guarantee is a personal guarantee given specifically by a director of the borrowing company. Lenders may also ask other people to guarantee: a shareholder who isn’t a director, a family member whose property is offered, or a spouse who co-owns the home being mortgaged.

When do lenders ask for a director’s guarantee?

• Unsecured loans to companies. Almost always. The guarantee is effectively the security, which is why our page on unsecured business loans treats it as standard.
• Secured loans. Often, as extra protection on top of a property mortgage or general security agreement.
• Equipment and vehicle finance. Commonly, alongside a registration over the asset.
• Trusts and corporate trustees. Directors of the trustee company typically guarantee; see business loans for companies and trusts.
• Sole traders. No guarantee is needed, because a sole trader is already personally liable for every business debt.

What protections do guarantors have under the Banking Code?

Banks that subscribe to the Australian Banking Association’s Banking Code of Practice, which took effect in its 2025 form on 28 February 2025, take on specific obligations to guarantors. Among them:

• Limited scope. A guarantee must be limited to a specific amount, or a specific loan plus related interest and fees, or to the value of a specified security.
• Information before signing. Prospective guarantors are entitled to key documents, such as the proposed loan contract, the borrower’s recent financial statements and relevant account information.
• Time to consider. The bank generally can’t accept a guarantee until three days after giving that information, although a director guarantor may choose to sign sooner.
• Requests to limit liability. A guarantor can ask in writing to limit their liability further, and the bank can refuse only in set circumstances.
• Withdrawal. A guarantor can generally withdraw before credit is provided.
• Enforcement order. The bank must generally enforce the borrower’s security before enforcing a mortgage over the guarantor’s home.

Some of these protections don’t apply in the same way to directors, sole directors and certain asset finance guarantees, and they apply to subscribing banks rather than every lender. Non-bank and private lenders set their own terms, so read every clause. Our guide to the 2025 Banking Code for small business covers the code more broadly.

How can you limit a director’s guarantee?

Before signing, ask for some or all of these:

1. A cap. A fixed maximum dollar liability, ideally close to the loan amount.
2. One loan only. Wording that limits the guarantee to the named facility, not all present and future debts.
3. No home mortgage. A guarantee without a supporting mortgage over your residence, if the lender has other security.
4. Several, not joint. With multiple directors, each liable only for a share rather than the whole debt.
5. A release trigger. Automatic release once the loan is repaid or the balance falls below a set figure.
6. A release on exit. A clause covering what happens if you resign or sell your shares.

You won’t win every point, but strong security, a solid trading record and competing offers all improve your leverage.

An illustrative example: what a guarantee can mean in dollars

Purely illustrative, involving no real business. Two directors of a hospitality company each sign guarantees for a $150,000 unsecured loan. Director A signs an “all moneys” guarantee with no cap. Director B negotiates a guarantee limited to that loan and capped at $160,000.

Two years later, the company also has a $60,000 equipment lease and a $40,000 overdraft with the same lender, and the business fails with $120,000 still owing on the original loan.

	Director A (all moneys, uncapped)	Director B (one loan, capped)
Original loan balance	$120,000	$120,000
Equipment lease shortfall after sale	$25,000	Not covered
Overdraft balance	$40,000	Not covered
Enforcement costs	$8,000	$8,000
Potential personal exposure	$193,000	$128,000

Same company, same failure, a $65,000 difference in what each director could be pursued for, purely because of how the guarantee was worded.

Can you get a business loan without a personal guarantee?

Sometimes, though it’s uncommon for smaller companies. The most realistic paths are:

• Strong business property security with a low loan-to-value ratio, so the lender’s risk is covered by the asset.
• Invoice finance, where repayment comes from your customers paying their invoices.
• Equipment finance on a high-value, resaleable asset.
• Larger, established companies with audited financials and substantial balance sheets.

Even in these cases many lenders still ask for a guarantee. Treat “no guarantee” as a negotiating goal rather than an expectation, and focus on limiting the guarantee if removing it isn’t possible.

What happens if the company can’t repay?

The lender usually pursues the company and its security first, then turns to guarantors for any shortfall. Talk to the lender early if repayments are at risk; options are far wider before a default. Our guide to missed business loan repayments explains what to do.

Questions to ask before you sign a guarantee

• Does this guarantee cover only this loan, or all present and future debts to the lender?
• Is there a maximum dollar limit, and does it include costs and enforcement charges?
• Is a mortgage over my home part of the guarantee?
• If there are several guarantors, am I liable for the whole debt or a share?
• How and when will I be released, including if I resign or sell my shares?
• Will you tell me if the company falls behind on repayments?
