Expert answer

How do I avoid family conflict when buying a relative’s business?

Treat it as the deal it would be with a stranger: record how the price was set, put payment terms and the seller’s future role in writing, and give each side its own advisors. Tax rules can substitute fair market value where the parties do not deal at arm’s length, so a family price needs a basis.

Family sales rarely fail over the price alone. They fail over what was never said: who decides, what the seller keeps doing, what happens to relatives who are not buying, and what happens when a payment is late. The business is the same business, but everyone is in two roles at once. Writing each point down turns an understanding into terms that both sides read the same way.

Put the price on paper and say how it was set

BDC says a business-purchase loan applicant provides the agreed price and how it was determined, and its loan list includes taking over a family business. The tax rules point the same way. Under subsection 69(1) of the Income Tax Act, where parties do not deal at arm’s length, a buyer who pays more than fair market value is treated as having acquired the property at fair market value, and a seller who disposes of property to such a person for less is treated as receiving fair market value. A gift is treated the same way whoever receives it. Whether a given family relationship falls inside that rule is a question for an accountant.

Settle the terms that cause arguments later

  • When payments are due and what happens if one is late.
  • What the seller will keep doing after closing, and the date it ends.
  • Which other family members have an interest, and whether they have agreed in writing.
  • How a disagreement is raised and resolved before it reaches court.

Keep the formalities a stranger would face

CRA’s page on selling a business describes the seller contacting the tax services office about the business number and closing payroll and GST/HST accounts where they exist, and it describes giving a value to each asset, goodwill included. It offers no separate guidance for sales to relatives, so plan on the same steps.

Give each side its own advice

BDC’s seller guide lists the accountant, lawyer and valuator among the professionals a sale team typically includes. Between relatives, advice is easier to trust when each side has its own, and a neutral valuation gives both a figure neither chose. Our buyer advisory team checklist lists the roles.
