Splitting a business fairly when only one child runs it

Splitting a business equally among children feels fair on the day the will is signed. It often stops feeling fair within a few years, once one child has spent a decade building the company and the others have not set foot in it. This is how owners actually structure around that gap, and what happens when they do not.

Key takeaways

  • • Equal is not the same as equitable: giving every child the same number of voting shares treats years of unpaid sweat equity the same as a name on a will.
  • • Non-voting or preferred shares let inactive children share in the business’s value without holding a vote over decisions they have no role in making.
  • • Life insurance on the parent’s life, payable outside the business, is the most common way to give inactive children an inheritance without giving them a stake in the company.
  • • Under CBCA and OBCA-style oppression provisions, a shareholder can go to court where a corporation’s conduct is oppressive or unfairly disregards their interests — equal shares do not prevent an active child from later triggering exactly that kind of claim from an inactive one, or the reverse.
  • • A marriage contract can matter as much as the share structure itself where shares are gifted rather than sold to a child.

SECTION 01 OF 05

Equal shares and a fair outcome are different problems

An estate plan that gives three children equal shares in the family business looks even-handed and often is not: it hands the same governance rights to the child who has run the company for fifteen years unpaid and the two who have never worked there. Two children in the business and one outside it is the illustration of what actually decided a real split — and it was a tax rule, not the family's own arithmetic, that ended up mattering most. Treadstone Law's answer on several siblings inheriting equal shares identifies the structural risk directly: with no one holding a majority, deadlock is the default outcome of equal voting shares among people who no longer agree on how the business should be run.

SECTION 02 OF 05

Separating who governs from who benefits

The usual fix is to separate voting control from economic value. The active child receives or retains the voting common shares that come with running the business; inactive children receive non-voting or preferred shares that share in dividends and eventual sale proceeds without a vote over decisions they have no basis to make day to day. This is the same share-class mechanism behind an estate freeze — see the estate freeze — applied to a different problem: fairness among siblings rather than fixing a founder's value.

SECTION 03 OF 05

Insurance as the equalizer, kept outside the business itself

Where the business cannot be split without damaging it, life insurance on the parent's life, payable directly to the inactive children rather than through the company, is the most common way to give them a real inheritance without giving them a stake in a business they have no role in. This runs on the same funding logic used elsewhere for a death-triggered buy-sell obligation — see funding a buy-sell obligation with insurance — pointed at a different beneficiary.

SECTION 04 OF 05

What happens when the structure is wrong and someone feels shut out

Both the corporate oppression remedy and family estate-litigation routes exist for exactly this situation. Under the oppression provisions in the federal and provincial corporate statutes, a shareholder, director or officer can apply to a court where a corporation's affairs are conducted, or the directors' powers exercised, in a manner that is oppressive, unfairly prejudicial to, or that unfairly disregards their interests — and the court has a wide menu of orders available, including forcing a buyout. Giving every sibling equal voting shares does not prevent this claim; it can just as easily produce one, from the active child against siblings who contribute nothing but can outvote every operating decision, or from an inactive one who feels frozen out of information and value.

SECTION 05 OF 05

Where shares are gifted, the recipient's own marriage can matter too

Do shares gifted to my child stay protected if their marriage breaks down covers a question that sits alongside the split itself: how the shares are held can determine whether they are protected from a future equalization claim in the recipient's own marriage. Treadstone Law's guide to marriage contracts protecting a family business or inheritance covers the tool most commonly used to address it.

Common questions

If a parent gives every child equal voting shares in the family business, does that prevent disputes between the child who runs it and the ones who don’t?

No, and it can just as easily cause one. Under the oppression provisions in Canada’s corporate statutes, a shareholder can go to court where a corporation’s affairs are conducted in a manner that’s oppressive or unfairly disregards their interests — and equal voting shares can produce that claim from either side.

How do families typically give an inactive child a share of the business’s value without giving them a vote over how it’s run?

The active child usually keeps the voting common shares, while inactive children receive non-voting or preferred shares that share in dividends and eventual sale proceeds without a vote over day-to-day decisions. Life insurance on the parent’s life, paid directly to the inactive children rather than through the company, is also commonly used as the equalizer.

If shares are gifted to a child rather than sold to them, does that affect whether the shares are protected if that child later divorces?

It can. How gifted shares are held can determine whether they’re protected from a future equalization claim in the recipient’s own marriage, which is why a marriage contract is often used alongside the share structure to protect shares gifted to a child.

Canadian small-business transaction data is not published anywhere, so most valuations in this country quote an American benchmark.
