Buying out a business partner after death or serious illness

When a business partner dies or becomes too unwell to keep working, the surviving owner usually ends up buying their share, either under a buy-sell agreement or by negotiation with the partner or their estate. The money typically comes from insurance the owners held on each other, a business loan, payments to the family over time, or a combination. The lender’s job is to fund the gap; your job is to get the price and the paperwork settled.

It’s one of the toughest situations a business owner faces. You’re grieving or supporting a friend through illness, customers are asking questions, and you’re suddenly doing two people’s work. This guide focuses on the practical money side so you know what to expect.

How does a buy-sell agreement shape the buyout?

A buy-sell agreement is the document that turns a crisis into a process. The WA Small Business Development Corporation describes it as a legally binding agreement between co-owners that sets out what happens if an owner dies, is forced out or chooses to leave, including who can buy the share, which events trigger a sale, and the price.

If you have one, read it before anything else. It will usually tell you:

• What triggers the buyout: death, total and permanent disability, a defined period of illness, or retirement.
• Who buys: the surviving owner, the business itself, or either.
• How the price is worked out: a fixed figure updated each year, a formula, or an independent valuation.
• How it’s paid: from insurance proceeds, in a lump sum, or over time.

If you don’t have one, the partnership or shareholder agreement may still set out what happens when an owner leaves. Where neither exists, the buyout becomes a negotiation, and getting legal advice early protects both sides.

Where does the money usually come from?

Source	How it works	Things to watch
Insurance on each owner	A policy pays out on death or disability and funds the purchase	Cover may not have kept pace with the business’s value
Business loan	The surviving owner or the business borrows to pay the share	Lender needs a signed agreement and a clear signing party
Staged payments	The family or estate is paid part now and the rest over time	Instalments reduce borrowing but count against affordability
Surviving owner’s own funds	Savings or property equity	Leaves less buffer for the transition period

Business Victoria’s guidance on preparing to exit mentions insurance that partners can take out on each other, and notes that a buy-sell arrangement can pay part of the departing owner’s share upfront with the rest by scheduled repayments.

The most common real-world story is a mix. Insurance was taken out years ago and covers some of the price. The business has grown since, so a loan covers the difference, sometimes with a short instalment period for the final portion.

While the buyout is being sorted, keep a close eye on cash. Customers may hold back orders until they know who’s in charge, and you may need to pay someone to cover your partner’s work. Talk to key clients early, reassure staff, and keep the bookkeeping current, because those same bank statements will be what a lender reads when you apply. A business that looks steady through the transition is far easier to fund than one where the figures have quietly slipped.

What’s different when a partner has died?

The person on the other side of the table changes. Instead of negotiating with your partner, you’re dealing with the executor or administrator of their estate, acting for the beneficiaries, who are often your partner’s spouse and children.

That brings a few practical issues:

• Authority to sign. The executor may need a grant of probate, or an administrator may need letters of administration, before they can deal with the shares or partnership interest. That can take time.
• The family’s needs. The surviving spouse may need money sooner than the estate process allows. A clear, fair offer and a realistic timeline help everyone.
• Guarantees and debts. If your partner guaranteed business loans, their estate will want those guarantees dealt with. That usually means refinancing the facilities into the continuing owner’s name. The business debt refinance page explains how that works.

Where a payment deadline arrives before longer-term funding can be finalised, a short-term facility such as bridging finance can sometimes hold things together until the main loan is ready.

What’s different when a partner is seriously ill?

With illness, you’re usually still dealing with your partner directly, or with someone legally appointed to manage their affairs if they can’t do it themselves. The emotional weight can be heavier, because the relationship is ongoing.

Clarity helps. Agree whether the trigger in your agreement has actually been met, how the price will be calculated, and what happens to your partner’s income in the meantime. If the illness is uncertain or temporary, some owners agree an interim arrangement before committing to a full buyout. Lenders will want the final position agreed and signed before they fund.

If you’re working through a buyout in either situation, tell us where things stand in a short enquiry. There’s no credit check, and a real person will talk it through with you.

What will a lender want to see?

The checklist is similar to any partner buyout loan, with a few extra points:

1. The signed buyout agreement, or the buy-sell agreement and a notice that the trigger has occurred.
2. Evidence of authority for whoever signs for the departing owner, such as an executor, administrator or other legally appointed representative.
3. The price and how it was reached, with any valuation report.
4. Insurance proceeds received or confirmed, and the gap to be funded.
5. Trading figures: tax returns, BAS and recent bank statements.
6. A plan for the partner’s role: who now handles their clients, licences or technical work.
7. Security details, if the loan is property-backed.

Unsecured options, typically $5k to $500k and sized on turnover and bank statements, can suit a smaller gap where the business is trading strongly. Larger payouts are often funded with property-secured business loans from $20k to $5m, written as first or second mortgages or caveat loans. Many surviving owners use equity in their home through a second mortgage behind the existing home loan.

Illustrative example

Illustrative only. Two partners have run a joinery business for fifteen years. One dies unexpectedly. Their buy-sell agreement sets the price by independent valuation, which comes in at $700k for the late partner’s half. The life cover they took out on each other a decade ago pays $400k.

The surviving partner deals with his late partner’s executor. Once probate is granted, they sign the transfer. The $300k gap, plus $110k to refinance a vehicle and machinery facility both partners had guaranteed, is funded with a second mortgage over the surviving partner’s home. The estate receives the full price at settlement and the guarantee is released. The lender’s comfort comes from the trading history, the agreed valuation, and the senior joiner who has stepped up to run the workshop floor.
