Personal guarantees: what you are actually signing

A personal guarantee is a promise that if the company can't pay a lender back, you will — personally, out of your own assets, not the company's. It sits behind the loan as a backstop, not alongside it. Most New Zealand business lending to a limited company still asks a director for one, because a young or asset-light company often has no credit history and nothing worth repossessing on its own. Reading the document properly before you sign — specifically the wording around "all obligations," what's offered as security, and what the independent legal advice certificate actually certifies — is the difference between a guarantee that does exactly what you agreed to and one that quietly does more.

Key Takeaways

What you're actually promising

Official guidance from Consumer Protection defines a guarantor plainly: someone who "promises to act as a back-up for someone signing a credit contract, such as mortgage, car loan, credit sale (also called hire purchase)." That's a different role from a co-borrower, who helps make the regular payments alongside the primary borrower. A guarantor isn't expected to pay anything under normal circumstances — you're the lender's last resort if the borrower fails to pay.

Lenders typically ask for a director's personal guarantee for a company loan for the same reasons Consumer Protection lists generally: the borrower — in this case, the company — has no credit history, a bad or thin credit score, or too few assets worth repossessing on its own. A brand-new limited company almost always falls into one of these categories, which is exactly why the guarantee request lands on the director's desk rather than staying with the company.

Before you sign, the lender has specific legal duties toward you as the prospective guarantor, not just toward the company borrowing the money. Lender responsibility principles under the Credit Contracts and Consumer Finance Act protect your rights specifically when you act as a guarantor, separately from when you borrow yourself. In practice, before you sign, the lender must:

Stage	What the lender is required to do
Before you sign	Explain what being a guarantor actually means; check you personally can afford to take over the repayments without substantial hardship; give clear information about the credit contract; not force you — or let anyone else force you — into agreeing
While the guarantee is live	Keep you updated on material changes, within strict timelines — for example, within 5 working days if the borrower's loan amount is increased
If it's called on	Act reasonably — a dispute resolution scheme has already found against a lender for letting interest and fees stack up for months before it went after a guarantor

That last row isn't hypothetical. In one adjudicated case described in Consumer Protection's own guidance, a guarantor was pursued for nine months of missed payments plus default interest and fees that had been allowed to accumulate. The dispute resolution scheme found the lender took too long to seek repayment and had let the debt grow unnecessarily — it reduced the amount the guarantor had to pay and agreed a different repayment schedule. The lesson isn't that guarantees are toothless; it's that the lender's own conduct matters, and a guarantor who's been sitting on a growing default has grounds to push back on how long the lender waited.

"All obligations" — the wording that quietly expands

This is the single clause worth reading twice before you sign anything. An "all obligations" guarantee means you promise to cover all of the borrower's debts with that lender — now and in the future — not just the specific facility you discussed when you agreed to guarantee. Guarantee a mortgage under this wording and you may also be covering that person's credit card. Guarantee a business loan and you may also be covering an overdraft, or a facility taken out well after you signed, that you were never told about.

Consumer Protection's own published example shows exactly how this plays out. A lender asked guarantor parents — described in the example as Mike and Betty — to guarantee their son's car loan under an all-obligations clause. The lender later tried to make them pay not just the car loan but an undisclosed personal loan taken out afterward. The dispute resolution scheme found the lender had never told the guarantors about the personal loan, and had never checked whether they could actually afford to guarantee it. The scheme ordered the lender to cancel the guarantee for that second, undisclosed debt — though the guarantors still owed the original car loan.

The practical takeaway sits in two places. First, read the obligations clause specifically — does it name one facility, or does it say "all obligations," "all present and future indebtedness," or similar language that reaches beyond the loan you're being asked about today. Second, know that you have a real, exercisable right here: you can ask the lender to cancel an all-obligations guarantee. If the lender agrees, you remain on the hook for the original loan, but you're released from covering anything the borrower takes on afterward. It's worth doing this the moment the original purpose for guaranteeing has been served, rather than leaving an open-ended promise sitting on a lender's file indefinitely.

Capping it, or limiting it to one loan

You are also entitled to ask for a guarantee to be limited to just the specific loan in front of you, or capped at a maximum dollar figure — Consumer Protection's own advice to prospective guarantors is to go in with a figure in mind that you could genuinely afford to repay, and ask for exactly that limit. The lender is under no obligation to agree. But there is no cost to asking, and a capped or single-loan guarantee is a fundamentally different, more contained commitment than an open-ended one — worth raising explicitly in the conversation before you sign, not something to assume the lender will offer unprompted.

The family home — and how it's actually put at risk

Consumer Protection's general advice to anyone considering becoming a guarantor is blunt: avoid offering assets worth more than the amount owed as security, such as your home or car, because they can be repossessed and sold if repayments fall too far behind. That's the plain-language version. The mechanical version is worth understanding too, because it explains why the family home is a different kind of risk from the business assets a lender might also be looking at.

Business assets — plant, equipment, receivables, stock — are typically secured through the Personal Property Securities Register, where a lender registers a financing statement against specific collateral. Land and buildings are explicitly excluded from that system, along with ships over 24 metres. A lender's interest in a family home isn't taken through a PPSR registration at all — it's taken by way of a mortgage registered against the land title itself. Different register, different mechanism, same practical outcome if things go wrong: the asset can be sold to recover the debt.

This is directly relevant if a spouse or partner — rather than the director themselves — is the one being asked to guarantee, because the family home is often held jointly. ANZ's own instructions to the solicitors who act on its lending specifically flag this scenario: solicitors are told to watch for a guarantor who "receives no benefit from the transaction" or who "may be putting personal assets at risk" — language that maps precisely onto a spouse guaranteeing a company loan they have no stake in, secured against a home they jointly own. That's not an incidental line in the paperwork; it's the bank's own checklist anticipating exactly this situation.

Does a trust protect the family home from a guarantee? It depends on how and when the trust was settled, what the trust deed actually says, whether the guarantor is also a trustee or beneficiary, and how the specific guarantee and mortgage documents define the property being offered — this is not a question with one general answer. If the family home sits in a trust and a lender is asking for a guarantee, get a lawyer who can read the trust deed and the loan documents together before you assume the trust changes your exposure either way.

The independent legal advice certificate — what it's really for

Almost every guarantee a lender asks a director to sign will require an independent legal advice certificate before it's enforceable. The consumer-facing framing of this is usually "so you understand what you're signing" — which is true, but it's only half the story, and the more candid half is worth knowing.

ANZ's own general instructions to the solicitors who act on its behalf are unusually direct about the other half: the bank states plainly that it relies on the solicitor's certificate as its own confirmation that it has met its lender responsibilities under the Credit Contracts and Consumer Finance Act, the Responsible Lending Code, and common law. In other words, the certificate is doing two jobs at once — informing you, and giving the lender its own paper trail proving it did things properly. That's not a reason to distrust the process; it's a reason to actually use the meeting rather than treat it as a formality to get through.

What the process is meant to look like, per ANZ's own instructions: the solicitor must provide you with a copy of the guarantee and explain the key information on its front page and the acknowledgments above where you sign. "Independent" has a specific meaning here — it means advice from a solicitor who is not advising the borrower, a security provider, or another guarantor in the same deal. If your own company's solicitor is also meant to be advising you independently on the guarantee, that's a conflict worth raising, not accepting quietly. ANZ's instructions also specifically direct solicitors to make sure a guarantor related to the borrower — a spouse, an inactive director, a family member — is not rushed or inappropriately influenced into signing, and has had genuinely enough time to review and understand the document first.

One detail that catches people out: you (or the borrower, or the security provider) pay for this legal advice, including the solicitor's costs, even if the loan transaction ultimately doesn't go ahead. It isn't a free service the bank is doing you a favour with — it's a cost built into taking on the guarantee.

If you want advice from someone with no connection to the transaction at all, Consumer Protection specifically recommends Community Law Centres as a source of independent legal advice for prospective guarantors — there are 24 of them nationwide, offering legal information, advice, assistance and representation. There are also 83 Citizens Advice Bureaus around the country that can point you toward one, even if they don't give the legal advice directly themselves.

Getting out later

Cancelling an all-obligations guarantee removes you from the borrower's future debts, but — as covered above — it does not release you from the original loan you guaranteed; that stays live until it's actually repaid or the lender separately agrees to release you from it.

Property law also gives a guarantor who pays out on a called guarantee certain rights — including a right to have the lender's securities assigned across, and rules governing the position between multiple guarantors of the same debt, under the Property Law Act 2007. Get a lawyer to confirm exactly how these apply to your own documents before you rely on them.

Selling your shares or resigning as director doesn't automatically end a guarantee. Treat a signed guarantee as remaining live until a lender confirms your release in writing — the same pattern that applies to cancelling future debts under an all-obligations clause, where you have to actively ask and the lender doesn't have to agree, is the safest assumption here too. If you're negotiating an exit from a company, make getting that release part of the deal itself, not an afterthought to chase once the sale has already closed.

Frequently Asked Questions

If I guarantee my company's loan, can the lender come after me before it's even chased the company? The published definition of a guarantor is specifically that you are the lender's last resort — the structural role is to be chased after the primary borrower fails to pay, not instead of it. Read your specific guarantee to check it doesn't depart from that ordinary structure.

Can I limit a guarantee to a dollar amount I'm comfortable with? You can ask. Go in with a specific figure you could genuinely afford to repay and request that cap, or a limit to a single named loan. The lender doesn't have to agree, but there's no cost or downside to asking clearly, upfront.

Does an independent legal advice certificate mean the lender has definitely done everything right? No — it means the lender has evidence that it took the steps it's required to take. Read the certificate meeting as your opportunity to actually raise concerns and get real answers, not as a formality that automatically protects you regardless of what you ask.

Is the family home protected just because it's not registered on the PPSR like business assets are? No — land, buildings and larger ships are excluded from the PPSR specifically because a different mechanism applies: a mortgage registered against the land title. The home is still very much at risk if it's offered as security; the register it sits on is just a different one.

Once I've paid off the original loan, am I automatically free of the guarantee? Not necessarily, and this is exactly why the "all obligations" wording matters. If the guarantee was written to cover future debts with the same lender too, it can remain live even after the loan you originally had in mind is repaid, unless you've separately asked the lender to cancel it.

Assuming a guarantee only covers the specific loan discussed at the time. "All obligations" wording can quietly extend to future debts with the same lender that the guarantor is never separately told about.
