Business protection

Business debt protection

Most small business lending is personally guaranteed, and most of those guarantees are secured against the family home. If the owner dies the debt does not die with them: it lands on the estate, and the house stands behind it.

In short

  • Business debt protection is life, trauma and disability cover sized to the borrowings a business could not repay if the owner were gone.
  • The exposure is rarely just the term loan. Overdrafts, equipment finance, trade credit and shareholder current accounts all count.
  • Personal guarantees are the central issue. Small business bank lending here is routinely guaranteed by the owners and secured over the family home.
  • A guarantee is a personal debt. It does not end on death — the lender can claim against the estate.
  • So the family can lose the house because of a business they no longer own and no longer benefit from.
  • Work out the exposure from the loan documents, not from memory. Owners almost always underestimate what they have signed.

What this is, plainly

Ask a business owner what the business owes and you usually get the term loan figure. Ask the bank and the list is longer: the term loan, the overdraft limit, asset finance on the ute and the plant, a business credit card — and behind it all a set of personal guarantees signed years ago and not read since.

Business debt protection is cover sized to that total, arranged so the money arrives where it is needed if the owner dies or is permanently unable to work. It is the least glamorous form of insurance and one of the most consequential, because debt survives everything else. A business can lose revenue and shrink. It cannot shrink its way out of a facility that has been called.

Two related events need planning for. The lender reviews or withdraws the facility: banks lend to small businesses partly on the strength of the people running them, and the death or permanent disablement of a principal is usually a reviewable event. Or the loan is repayable and the money is not there, in which case the security gets tested — and for most small businesses, the security is the house.

Personal guarantees and the family home

This gets the least attention and deserves the most, so it is worth setting out step by step.

  1. 1The company borrows. On paper the debt is the company’s, and the owner’s liability is limited to their shareholding.
  2. 2The bank, knowing the company has few assets, asks the owners to guarantee the borrowing personally. Almost every small business owner signs one.
  3. 3The guarantee is usually supported by a mortgage over the owner’s home, turning a personal promise into a secured claim over the family’s largest asset.
  4. 4The owner dies. The company’s ability to service the debt drops, and the facility comes up for review.
  5. 5The lender calls on the guarantee. It is a personal liability, so the claim is made against the deceased’s estate.
  6. 6The estate pays, or the security is realised — and the family home stands behind a business that may no longer be trading.

Two details catch people out. Most owner guarantees are joint and several, so each guarantor can be pursued for the whole debt rather than their share. And many are all-obligations guarantees, covering future advances as well as the loan in front of you when you signed.

Working out the real number, from the documents rather than from memory

  • Current term loan balances, not the original amounts.
  • Overdraft and credit facility limits — insure the limit, since that is what can be drawn.
  • Asset and equipment finance, including anything on a lease with a residual.
  • Business credit cards and trade credit accounts, which usually sit behind a guarantee too.
  • Shareholder current accounts in credit, which the estate may call for.
  • Any lending the owner took personally and injected into the business.
  • The guarantees: who signed what, whether they are joint and several or all-obligations, and what security supports them.

Add it up, then decide how the cover should be owned. If the exposure is the guarantee and the point is to protect the estate, personal ownership is often more reliable than company ownership, because company-owned proceeds are company assets with other creditors in the queue. Ask your accountant and lawyer — the answer changes the tax analysis.

Not sure what cover you actually need?

That is the question an adviser is there to answer. Tell us your situation and a licensed New Zealand adviser will compare the market and come back with a written recommendation — including where you can cut cover you do not need.

No cost to you and no obligation. General information only — not personalised financial advice.

What to watch for

These are the details that decide whether the cover does what you expected. Read them before you compare on price.

  • Whether the cover matches the exposure today. Debt moves, and revolving facilities move fastest.
  • Whether guarantees are joint and several — if so, each guarantor may need cover for the whole debt, not a share.
  • Whether the guarantee is an all-obligations guarantee capturing future lending as well as the current facility.
  • Whether disability is covered. A permanently disabled owner cannot service debt any better, and is still alive to be pursued.
  • Whether the bank has required an assignment of the policy. An assigned policy pays the bank first.
  • Whether the estate has liquidity before the insurance arrives. Probate takes time; overdrafts do not.

Where an adviser makes a difference

Every New Zealand insurer writes business debt cover to its own wording, and the words are where the money is. Two policies that look identical on price can pay very differently when it matters. Closing that gap is the entire job of an adviser.

  • An adviser can read the facility documents and the guarantees alongside you, which a bank’s own insurance arm has little incentive to do carefully.
  • Where a bank requires cover as a lending condition, an adviser can usually place it more competitively than the bank-branded option offered at the same meeting.
  • Decreasing sums insured track an amortising term loan but are the wrong shape for a revolving overdraft. Matching structure to facility saves real money.
  • An adviser can coordinate ownership and any assignment with your accountant and lawyer.

There are three ways to buy life cover in New Zealand, and they are not equivalent. You can buy direct from one insurer, which means you see one product range and one underwriting appetite. You can buy through your bank, which usually means a single insurer’s product sold under the bank’s brand, often with narrower definitions. Or you can go through an adviser, who quotes several insurers at once and is required to put your interests first.

The premium you pay is the same either way. Insurers build adviser commission into their pricing whether or not an adviser is involved, so going direct does not get you a discount — it just removes the person whose job is to argue your corner at application and at claim time.

  • An adviser can see which insurer is currently taking your health history on standard terms, and which one will load or exclude it.
  • An adviser can structure cover across two insurers if that produces a better outcome than putting everything with one.
  • An adviser handles the underwriting back-and-forth, and is the person who chases the claim when a family is least able to.
  • An adviser has to document why the recommendation suits you, which is a written record you can hold them to.

What happens if you get in touch

We are a referral service, not an insurer. We do not quote premiums and we do not sell policies. What we do is put you in front of one licensed New Zealand adviser who can compare the market properly.

  1. 1

    You tell us what you are looking at

    The form takes about a minute. Nobody asks for your medical history on a web form — that conversation happens with the adviser, properly, and only once you have decided to proceed.

  2. 2

    An adviser calls you

    A licensed New Zealand adviser talks through your situation: who depends on you, what you owe, what you already have in place, and what you are actually worried about.

  3. 3

    They compare the market

    The adviser quotes across the major insurers, checks which of them will take your health history on the best terms, and puts the options side by side in writing.

  4. 4

    You decide, in your own time

    There is no obligation and no cost to you. If the answer is that you already have enough cover, a good adviser will tell you that.

Frequently asked questions

If a director dies, does the bank call in the business loan?

It depends on the facility, but the death or permanent disablement of a principal is commonly a reviewable event in small business lending. Even a supportive bank has to reassess whether it still has a viable borrower. Plan for the facility being reduced or withdrawn.

Does a personal guarantee end when the guarantor dies?

No. It is a personal liability and becomes a claim against the deceased’s estate. That is precisely why it needs insuring: the obligation outlives the person who signed it, and the estate — and therefore the family — has to answer it.

Can the family home really be lost because of a business loan?

If the home secures a guarantee of that loan, yes — and this is the ordinary structure of small business lending, not an unusual case. The protection is not to avoid guaranteeing, since the bank will insist, but to hold enough cover that the guarantee can be met without touching the house.

Should business debt cover be owned by the company or personally?

It depends whose obligation you are protecting. Company-owned cover is tidy for company debt, but the proceeds rank alongside other creditors. Personal ownership is generally more reliable where the real exposure is a guarantee. Get your accountant to confirm the position before the policy is issued.

Do we need to insure the overdraft as well as the term loan?

Usually yes, and at the limit rather than the current balance, because the limit is what can be drawn. Overdrafts are also the facility most likely to be withdrawn when a principal dies.

If both directors signed the guarantee, do we both need full cover?

If the guarantee is joint and several — and most bank guarantees are — each guarantor can be pursued for the entire debt, so insuring each of you for half leaves a gap. Have your lawyer confirm which form you signed.
