Key takeaways
  • The house is held by the estate trustee for the beneficiaries, so a buy-out is a transfer from the estate, not a private deal between siblings alone.
  • Conveying or dividing the estate requires the concurrence of the adult beneficiaries, plus the Children's Lawyer or Public Guardian and Trustee approval where minors or incapable persons are involved.
  • Ontario's guidance is to obtain the certificate of appointment before anyone signs an Agreement of Purchase and Sale for estate real property.
  • Valuation, financing and tax all need to be sorted out before title moves, and the trustee should not distribute before tax and debts are dealt with.

A parent has died, the house is the main asset, and one of you wants to keep it. The others are happy to be paid out, but nobody is sure how that works. Is it just a cheque and a deed between siblings, or does the estate have to be involved?

In most cases the estate has to be involved. This article explains who has the legal power to transfer the house, how the price is usually set, how a buy-out is typically paid for, and the tax and creditor issues that can catch families by surprise. It is general information, not advice on your particular estate.

Who can transfer the house?

When someone dies, their property vests in the personal representative, who holds it as trustee for the people entitled to it. That means the house is not owned outright by the siblings yet, and a buy-out is a transfer from the estate.

Ontario's guidance says probate is normally required where the deceased owned real property that does not pass by right of survivorship, and that if the property must be sold, the certificate of appointment of estate trustee should be obtained before anyone enters into an Agreement of Purchase and Sale. Where no certificate was obtained, a transmission by a personal representative must state either that a court appointed the estate trustee or that no application was made because the estate is worth no more than $50,000, and an indemnity covenant to the Land Titles Assurance Fund (Form 54) must be provided. The Registrar's waiver of the certificate applies only to the first dealing after conversion from Registry to Land Titles. Whether any of this could apply to your property is worth confirming with a lawyer.

Do all the siblings have to agree?

The personal representative can sell estate property in order to distribute it, not only to pay debts. But a sale made only to distribute is not valid against a beneficiary who does not agree unless beneficiaries holding at least one-half of the interests approve it. Conveying or dividing the estate also requires the concurrence of the adult beneficiaries.

In practice, a buy-out works best when every adult beneficiary signs off in writing on the price and terms. If one sibling refuses, the family may need legal advice on options, which can include a sale on the open market or a court process. What is available depends on the will and the facts.

If any beneficiary is a minor or is mentally incapable, the Children's Lawyer or the Public Guardian and Trustee must also approve. The Children's Lawyer must be served on an application for a certificate of appointment if any beneficiary is under 18.

Setting the price

The most common source of conflict is the price. A buy-out is fair only if everyone accepts the number, so it helps to rely on something neutral rather than one sibling's opinion. Typical options are a written appraisal from a qualified appraiser, two appraisals averaged, or exposing the house to the market and letting the buying sibling match the best offer. The right choice depends on the family.

Remember that the buying sibling usually has their own share in the estate. How that share is credited against the price depends on the will and on what the estate owes, so it is worth confirming with a lawyer. The estate's debts and expenses are generally paid before beneficiaries receive their shares.

Valuation approachWhat it involvesThings to consider
One appraisalA single written valuation agreed by allLowest cost, but everyone must trust the appraiser
Two appraisalsEach side chooses one; the price is agreed between themMore cost, less room for suspicion
Market testThe home is listed and the sibling matches an offerReflects real value, but carries selling costs and delay

Paying for it: financing and tax

Most buying siblings do not have the cash to pay out the others. Common approaches are a new mortgage or a refinance, using their own share of the estate as part of the payment, or a payment plan agreed in writing. Speak to a mortgage professional early, because the lender's timeline can drive the whole process.

On the tax side, the CRA treats the deceased as having sold all capital property just before death at fair market value, and gains and losses are reported on Schedule 3 of the final return. A home the deceased ordinarily inhabited can be designated as a principal residence, which may exempt some or all of the gain, but the disposition must still be reported on Schedule 3 with Form T1255, and the designation covers only years up to the date of death. A cottage used for personal enjoyment is treated differently and is exempt only if designated as the principal residence.

An accountant can confirm how this applies, including what happens to any increase in value between death and the buy-out.

Risks that can derail a buy-out

These risks are why a buy-out should not be rushed. The trustee carries the personal exposure, so the trustee should be comfortable that debts, taxes and possible claims have been addressed before title moves.

What to do next

Frequently asked questions

Can I just buy my siblings' shares and have the deed changed?

The house is held by the estate trustee, so the transfer must come from the estate. The adult beneficiaries must concur in conveying or dividing the estate. A lawyer can prepare the documents and confirm what the land registry will require.

Do we need probate to do a buy-out?

Ontario's guidance says probate is normally required where the deceased owned real property that does not pass by right of survivorship. The guidance also says the certificate should be obtained before anyone signs an Agreement of Purchase and Sale for estate real property.

What if one sibling is a minor?

The Children's Lawyer must be served on an application for a certificate of appointment if any beneficiary is under 18. Conveying or dividing the estate also needs the approval of the Children's Lawyer or the Public Guardian and Trustee where minors or incapable persons are involved.

Who pays the tax on the house?

Gains at death are reported on the deceased's final return, and the estate trustee is responsible for paying taxes and debts. The principal residence designation may exempt some or all of the gain, but it must still be reported. An accountant can work out the figures.
