Personal guarantee on a business loan: what you're actually signing

By Samara Sweeney, Managing Director of Aurelius Capital ·

A personal guarantee is a legally binding promise by an individual to repay a business's debt if the business itself defaults. When a director signs one, the limited-liability protection a company structure normally provides disappears, at least to the extent of the guarantee.

This article is general information only, not legal or financial advice. Before signing any personal guarantee, get independent legal advice specific to your document and circumstances.

Why lenders require a personal guarantee

Most commercial and SME borrowing in Australia runs through companies or trusts. Both structures carry limited liability by design: the debts belong to the entity, not to the people behind it.

That creates a problem for lenders. If the company fails, the lender's claim sits in the insolvency queue alongside trade creditors and the ATO. A personal guarantee solves it. It brings one or more individuals (usually the directors) into the obligation directly. If the business defaults, the lender can pursue the guarantor personally without working through the insolvency process first.

For most unsecured commercial lending, a director's guarantee is standard. Even where property security covers the loan-to-valuation ratio comfortably, many lenders still require a guarantee to cover any shortfall on enforcement.

Limited vs unlimited guarantees

This is the distinction that matters most before you sign.

An unlimited guarantee covers the full outstanding balance: principal, interest, fees, and the lender's enforcement costs. There is no cap. If the business owes $800K and the lender spends $60K recovering it, an unlimited guarantor faces all of it.

A limited guarantee sets a ceiling. A $500K facility might carry a $250K limited guarantee. The guarantor's liability ends at that figure regardless of what the total debt becomes.

Lenders default to unlimited. Limited guarantees are often negotiable on well-structured deals with strong security positions, but the negotiation has to happen before signing. Understanding the true cost of a business loan, including the enforcement costs an unlimited guarantee can sweep in, is part of assessing what you're actually taking on.

Joint and several liability

Where two or more directors guarantee the same loan, lenders typically structure the obligation as joint and several. Each guarantor is individually liable for the full amount, not just their proportionate share.

The lender can pursue any single guarantor for the entire debt. If one director becomes insolvent, the other carries the whole exposure. A verbal agreement between directors to "split it 50/50" is not enforceable against the lender. It only operates between the directors, and only if it's properly documented in a separate agreement.

Where directors hold unequal ownership stakes and proportionate liability matters, that needs to be addressed in the guarantee document itself, not sorted out informally after signing.

What assets are at risk

A personal guarantee gives the lender recourse to your personal assets if the guarantee is called. What falls in scope:

  • The family home, if you hold equity in it or it's offered as additional security under the loan
  • Investment properties, on the same principle
  • Cash, savings and managed funds, which a court judgment and enforcement action can reach
  • Vehicles and other personally-held assets, which count toward the net asset position a lender assesses when working out what's recoverable

Jointly owned property is more complex but not automatically protected. A lender with a guarantee can pursue your share of a jointly owned asset. The co-owner's share is not directly at risk, but yours is.

Superannuation held in a regulated fund carries some statutory protection under Australian law, but the extent depends on the fund structure and the nature of the debt. Get specific advice if this is relevant to your position.

All-monies clauses

Read the guarantee document carefully for "all monies" language. This is materially different from a guarantee tied to a specific facility.

An all-monies clause means the guarantee covers everything the borrowing entity owes the lender, across current and future facilities, not just the loan being discussed today. If the business draws down an additional credit line six months later with the same lender, the guarantee may extend to cover it automatically.

Where multiple facilities are cross-collateralised under a single banking relationship, the guarantee can wrap the entire exposure. The guarantor's liability is not limited to the loan they thought they were signing for.

This is the clause that produces the most unwelcome surprises at enforcement. Confirm whether your guarantee is facility-specific or all-monies before signing anything.

Questions to ask before signing

These are starting questions, not a substitute for legal advice:

  • What is the cap? Is the guarantee unlimited, or does a dollar ceiling apply?
  • Is it all monies? Does it cover future facilities, or only this specific loan?
  • What triggers it? Look past missed payments: financial covenant breaches, cross-defaults on other facilities and material adverse change clauses all appear in standard commercial documents.
  • Can it be released? What are the conditions: full repayment, refinance, sale of the business?
  • What happens if I resign as a director? Guarantees typically survive directorship changes unless there's a specific release clause. You remain personally liable for debts incurred while the guarantee was in place.
  • Is director's guarantee indemnity insurance relevant? Some insurance products cover the scenario where the business defaults and the guarantee is called. A business insurance broker can assess whether it fits your situation.

Independent legal advice

Most commercial lenders require a guarantor to obtain independent legal advice before signing, and to provide a certificate confirming this. The requirement exists to reduce the risk of the guarantee being challenged later. Undue influence and inadequate disclosure are the most common grounds for challenge in Australian courts.

"Required by the lender" does not mean finding a solicitor to countersign a certificate as quickly as possible. It means sitting with a solicitor who has read the guarantee document, explained the default triggers, confirmed the scope of any all-monies clause, and walked through what enforcement looks like in practice.

How a broker fits in

The broker's role starts before the guarantee document arrives. Structuring the deal correctly, across facility type, lender and security position, determines what guarantee terms you'll be presented with.

Different lenders carry different security requirements. Some will accept a limited guarantee on a well-structured deal with strong underlying security. Others require unlimited guarantees as standard policy regardless of the deal profile. The six categories of business lender in Australia each carry distinct credit appetites, and guarantee requirements vary widely across them.

Where terms are negotiable, a broker with a direct credit relationship can push for a limited rather than unlimited guarantee, a facility-specific rather than all-monies clause, and a release mechanism tied to full repayment or business exit. That advocacy happens at credit level, before the documents are drafted.

The guarantee document is a legal instrument, and the broker doesn't provide legal advice. The job is to get the deal to the right commercial lending structure and the right lender, then point you to your solicitor before anything gets signed.

FAQ

Frequently asked questions.

Yes, in most cases. A lender who holds a personal guarantee can pursue the guarantor's share of a jointly owned property. The co-owner's share is not directly at risk, but the guarantor's equity is.

A limited guarantee caps the guarantor's liability at a specific dollar amount. An unlimited guarantee covers the full outstanding balance — principal, interest, fees, and enforcement costs — with no ceiling.

An all-monies clause means the guarantee covers everything the borrower owes the lender across all current and future facilities, not just the specific loan being signed for.

Most commercial lenders require it and ask for a certificate confirming you received independent legal advice. The solicitor's role is to explain what you're actually agreeing to, not just countersign a document.

The guarantee typically survives your resignation unless there is a specific release clause. You remain liable for debts incurred while the guarantee was in place.
