Buying Out a Sibling on Inherited Property in Canada

When one sibling wants to keep the inherited house and the others want their money, a buy-out is usually the fairest answer — the sentimental owner gets the property, the rest get liquidity, and the family avoids a forced sale to a stranger. It is also the transaction where well-meaning siblings most often skip the paperwork and regret it. A buy-out is a real property purchase, with a real price, real tax, and real title to transfer, even though it happens between people who grew up in the same house.

This guide walks through the steps in order — valuation, capital gains, land transfer tax, financing, and whether to do it inside or outside the estate — so the deal holds up and the relationships survive it. It is general information for the common-law provinces and territories, not advice for your transaction.

Step 1 — Agree on a fair value #

Everything downstream depends on the price, so start with a defensible one. Use an independent, qualified appraisal as of the relevant date rather than a realtor's casual opinion or an online estimate. Siblings who agree in advance on the appraiser, who pays for the appraisal, and what happens if two appraisals diverge (averaging them is common) remove the most likely source of later conflict. A number everyone accepts as neutral is worth more than a slightly higher or lower number that one party feels was imposed.

Step 2 — Understand the capital gains #

Here the inheritance rules work in your favour. Beneficiaries generally take inherited property at its fair market value at the date of death — a stepped-up cost base.^[1] If the buy-out happens soon after death at roughly that value, the selling sibling usually realizes little or no capital gain, because there has been little growth since the date of death.

The picture changes if the property is held for a while and appreciates. Then the selling sibling's share of the post-death growth can be a capital gain on their return, with 50% of the gain included in income at the 2026 inclusion rate. If the home qualified as the deceased's principal residence, that exemption applies to the estate's gain up to the date of death, not to growth after the beneficiaries own it.^[2] Note too that a property someone holds as an investment rather than a residence does not get the principal residence shelter for their own ownership period.

Step 3 — Budget for land transfer tax #

The buying sibling generally pays land transfer tax on the value of the interest they purchase from the other beneficiaries — not on the share they inherited directly. Rates, thresholds, and exemptions vary considerably by province, and some jurisdictions provide relief for transfers from an estate or between related persons. Because this can add a meaningful cost to the buy-out, confirm your province's rule (and any available exemption) before you settle on numbers. This is one of the clearest places to get a short, specific answer from a real estate lawyer.

Step 4 — Arrange the financing #

A buy-out has to be funded. The common routes are a mortgage on the property, applying your own inheritance or savings toward the purchase, or structuring the arrangement within the estate so that your share offsets part of the price. A lender will generally require the appraisal and clear title, which is another reason valuation comes first. If your inheritance itself is part of the financing, coordinate timing with the executor so the funds are available when you close.

Step 5 — Do it through the estate where possible #

A buy-out is usually cleanest handled during estate administration. With all beneficiaries consenting in writing, the executor can transfer the property directly to the buying sibling and pay the others their shares out of the estate — one transaction, clear records, fewer moving parts. Once assets have been distributed and the siblings hold the property as co-owners, the buy-out becomes an ordinary sale between them, with its own conveyancing and tax steps. Either way, document the deal with a signed agreement and releases.

When agreement fails #

If a sibling refuses to sell or the parties cannot agree on price, mediation is the sensible first move — it is faster and cheaper than litigation and preserves relationships. Where there is a true deadlock, partition legislation in most provinces lets a co-owner apply to the court for an order to sell the property and divide the proceeds. It works, but it is adversarial and expensive, and the property is usually sold on the open market rather than kept in the family — the opposite of what a buy-out is trying to achieve.

What we focus on at It's Simple Will #

The Will Creator lets a parent prevent this scramble entirely — for example, by granting one child an explicit option to purchase the home at appraised value and equalizing the others with cash or insurance. When a will is silent on a beloved property, the buy-out has to be negotiated from scratch under grief and time pressure. For the surrounding context, see our guide on inheriting with siblings.
