You set up a Pty Ltd company precisely so your personal assets — house, car, super — would be protected from business creditors. Then a supplier, landlord or financier slid a “personal guarantee” across the table. Sign it and the corporate veil disappears. Personal guarantees are one of the single biggest risks directors face in Australian business, and most are signed without any meaningful review.
What a personal guarantee actually does
A personal guarantee makes you, in your personal capacity, jointly and severally liable for your company’s debt. If the company defaults, the creditor can pursue you directly — bankruptcy proceedings, judgment against your home, frozen bank accounts. The corporate veil exists, but you signed a hole through it.
The “all monies” trap
Most standard guarantees are “all monies” — covering not just the current debt but every future debt the company incurs to that creditor. Sign a guarantee for a $5,000 trade account and three years later, when the account is at $80,000, you are on the hook for the lot. Always cap the guarantee to a defined dollar amount and a defined transaction.
The “continuing” trap
“Continuing” guarantees survive the end of the underlying contract, the sale of the business, even your departure as a director. Always insert a release mechanism — automatic release on a defined event, on written notice, or on substitution of an alternative security.
Joint and several liability
If two or three directors sign as guarantors, the creditor can pursue any one of you for 100 per cent of the debt. The other guarantors might be insolvent, overseas, or simply uncooperative. Always negotiate “several only” liability where possible — each guarantor liable only for their proportionate share.
Spousal guarantees and Garcia v NAB
The High Court in Garcia v National Australia Bank (1998) 194 CLR 395 established that a spouse who guarantees their partner’s business debt without independent legal advice and without a clear understanding of the transaction may have the guarantee set aside. If your bank or supplier insists your spouse co-sign, ensure they receive independent legal advice — and document it.
Statutory protections
The Australian Consumer Law (Schedule 2, Competition and Consumer Act 2010) prohibits unconscionable conduct in business transactions, including in the procurement of personal guarantees. Where the guarantor was pressured, lacked English fluency, did not receive proper disclosure, or was misled about the scope, the guarantee may be unenforceable. The ASIC Act adds equivalent protections for financial transactions.
Bankruptcy consequences
A guarantee enforced to bankruptcy strips you of company directorships under the Corporations Act 2001 (you cannot manage a company while bankrupt), tarnishes your credit for at least three years post-discharge, and can affect professional licences. The downstream cost dwarfs the upfront business benefit.
The document that protects you
A formal Contract Review reads the guarantee word by word, identifies every “all monies”, “continuing”, “joint and several”, or unconscionable clause, and provides plain-English red-line amendments you can request. Most creditors accept reasonable amendments — capped amount, defined transaction, several liability, release on departure — rather than lose the deal.
What Claim Done delivers
For a flat $79, Claim Done’s Contract Review parses your draft guarantee against Australian guarantee law and returns a clear PDF — flagged clauses, the legal exposure each creates, and the amendments you should request. Ten minutes versus the $500 to $1,200 a commercial lawyer would charge for the same review.
What happens after
Armed with the review, you negotiate the guarantee down before signing — capped, defined, time-limited, with a release path. If the creditor refuses every reasonable amendment, that is itself a signal worth heeding. The cost of the review is trivial compared to the cost of an enforced personal guarantee.
