Keeping the Family Cottage: One Sibling Buys Out Two Others

When their mother's estate left a cottage to three adult children in equal shares, one wanted to keep it and two wanted to be paid out. Getting to a number everyone could accept meant looking past the appraisal to the tax bill hiding behind it.

The situation

Soo-jin's mother died leaving an estate to be split evenly among her three children: Soo-jin, her sister Eleni, and her brother Dimitri. The estate held a house in Oakville, some savings, and a cottage the family had owned for decades. The will was simple on paper — everything divided equally — but it did not say what should happen to the cottage itself, and the three siblings did not agree.

Soo-jin, who worked as an investment advisor, wanted to keep the cottage in the family. Eleni and Dimitri, who lived farther away and used it rarely, wanted their shares turned into cash. Dimitri, who owned a construction company, needed the money to reinvest in his business. Soo-jin was named estate trustee in the will, which meant she was responsible for administering the estate fairly to all three beneficiaries — including her own competing interest in buying the property she was supposed to be valuing impartially. That conflict, more than the money itself, is what brought her to us.

None of the three siblings were adversaries by temperament. They had spent childhood summers at the cottage together and none of them wanted a fight over it. But without a structure for the buyout, ordinary sibling assumptions started hardening into positions: Eleni assumed a number based on optimism, Dimitri assumed one based on caution about the property's condition, and Soo-jin, understandably, hesitated to name a figure at all given that she was both trustee and prospective buyer. Three months after their mother's death, the estate still had not been able to move forward on distributing the cottage, and the longer it sat unresolved, the more the disagreement calcified into something closer to a standoff.

The problem

Three things made this harder than a simple buyout.

First, the siblings disagreed on value. Eleni had a number in mind based on what a similar property nearby had listed for; Dimitri, with a builder's eye, thought the cottage needed enough repair work that the asking price should come down. Neither figure was based on an actual appraisal, and the gap between them was large enough that no one trusted the other side's math.

Second, an estate trustee cannot simply set a price for an asset they intend to buy themselves. Ontario law expects an estate trustee to act in the best interests of all beneficiaries, not their own. If Soo-jin priced the cottage informally and the transfer was later questioned, Eleni or Dimitri could argue she had used her position to buy the property under value — a real risk to the validity of the whole arrangement, not just an awkward family disagreement.

Third, and least visible to the siblings at the outset, was tax. A cottage is not automatically treated like a principal residence for tax purposes. Because the Oakville house had already been claimed as the principal residence for the years in question, the cottage's transfer out of the estate on their mother's death triggered a capital gain, calculated as the difference between the cottage's value at death and what their mother had originally paid for it decades earlier. That gain created a real tax bill owed by the estate under the Income Tax Act — one that would reduce what was actually left to distribute, regardless of what number the siblings agreed the cottage was "worth." Nobody had priced that into the negotiation yet.

What we did

  1. Recommended an independent appraisal before any further negotiation. We advised Soo-jin, as estate trustee, to retain a neutral, arm's-length appraiser to value the cottage — not a real estate agent's informal opinion, and not a number either sibling proposed. An independent appraisal removed the accusation that either side had thumbed the scale, and gave all three siblings a figure they could each point to as fair.
  2. Calculated the after-tax value, not just the appraised value. We worked with the estate's accountant to estimate the capital gains tax the estate would owe on the cottage's deemed disposition. That tax came off the top before the remaining value was split three ways — meaning the appraised price and the amount actually available to distribute were two different numbers. Making this visible early avoided a second dispute later, when the payout came in lower than the appraisal implied.
  3. Separated Soo-jin's role as trustee from her role as buyer. We advised her to step back from any decision-making on the cottage's valuation and let the independent appraisal and the accountant's tax calculation speak for themselves, while a co-executor arrangement with input from both siblings governed the final sign-off. This protected the transaction from a later claim that she used her position to benefit herself.
  4. Structured a buyout Soo-jin could actually afford. Soo-jin did not have the full amount in cash. We drafted a promissory note secured by a mortgage against the cottage, payable to the estate — effectively to Eleni and Dimitri — over several years with interest, so they were compensated for waiting rather than simply told to wait.
  5. Insisted Eleni and Dimitri get independent legal advice. Because Soo-jin was both a sibling and the buyer, we required written confirmation that Eleni and Dimitri had each reviewed the buyout terms with their own lawyer before signing off. This is not a courtesy — it is what makes a related-party estate transaction defensible later if anyone questions how it was reached.
  6. Prepared the release and the transfer together. The buyout agreement, the mortgage, and each sibling's release of further claims against the estate were signed as one package, so the cottage transfer did not close while any part of the deal was still informal or unwritten.

The outcome

The independent appraisal came in below Eleni's initial figure and above Dimitri's, which — once the estate's capital gains tax was factored in — gave everyone a number they could live with even if no one loved it. Soo-jin kept the cottage. Eleni and Dimitri each received an upfront portion of their share in cash from the rest of the estate, with the balance owed on the cottage paid out over a fixed number of years under the promissory note, with interest.

It was not a clean win for anyone. Eleni had wanted a faster, all-cash payout and accepted the installment structure only after seeing that a forced sale of the cottage to raise full cash immediately would have meant losing the property from the family altogether — something none of the three actually wanted, whatever their disagreement over price. Dimitri got less than his initial number but more certainty than an open-ended dispute would have delivered, and secured financing meant he was not simply trusting his sister's promise to pay. The estate closed roughly eight months after the initial disagreement surfaced, slower than a straightforward estate distribution but far faster than the outcome likely if the siblings had ended up in court over the trustee's conflict of interest.

What made the compromise durable was that it was built on numbers nobody could credibly dispute — an independent appraisal and an accountant's tax calculation — rather than on family memory of what the cottage "should" be worth. Two years later, the mortgage payments continue on schedule and the cottage stayed in the family.

What you can learn from this

  • When an estate trustee also wants to buy an estate asset, get an independent appraisal and keep the trustee out of the valuation decision. Self-dealing, even well-intentioned, is the fastest way to have a transfer challenged later.
  • A cottage's appraised value and the amount actually available to distribute are often different numbers once capital gains tax on the deemed disposition is factored in. Price that in before siblings anchor on a figure.
  • If the buying sibling cannot pay in full immediately, a properly secured promissory note or vendor take-back mortgage can bridge the gap fairly, compensating the other beneficiaries for waiting rather than asking them to simply accept less.
  • Independent legal advice for each sibling in a related-party estate buyout is not optional formality. It is what protects the deal from being unwound later.
  • Deciding early whether anyone actually wants to sell the property outright can avoid a forced sale under co-ownership rules — a result that satisfies no one when the real goal was keeping the asset in the family.
