Proving a separated couple's own conduct had already split their home

The situation

Tamar and Baruch had been married for over twenty years before they separated, and the separation itself had been unusually calm for how much money was involved. Tamar, a veterinarian who ran her own practice, and Baruch, an accountant, had agreed early on to split most of their finances and simply get on with living apart, without either of them pushing hard for a final divorce that would have forced every remaining question onto a timeline. Their son Dilshan, now in his thirties, had watched the separation unfold from a distance, checking in with both parents regularly but staying out of the financial details by mutual, unspoken agreement among the three of them.

What Dilshan did not fully appreciate, and what neither of his parents seemed to have thought through carefully at the time, was that the Ottawa home they had bought together early in the marriage was still registered as a joint tenancy. Under a joint tenancy, when one owner dies, that owner's share does not pass through their will or estate at all; it passes automatically, immediately, to the surviving joint owner, in full, regardless of what any will says or was ever intended to say. Tamar and Baruch had divided their bank accounts, their vehicles, and most of their other property fairly quickly during the separation. The house, worth roughly nine hundred thousand dollars on its own within an estate that totalled somewhere between one and a quarter and two and a half million dollars, had simply never been dealt with, sitting untouched on the paperwork while the two of them moved on with separate lives.

Tamar's will, updated eighteen months after the separation began, left her entire estate to Dilshan, without exception. She had told him more than once, over dinners and phone calls, that she considered the house half hers in every meaningful sense and intended for her share to eventually come to him, not to Baruch, once she was gone. But updating a will does not sever a joint tenancy on real estate on its own; the two are separate legal steps governed by different rules, and Tamar had never taken the second one formally, whether through a lawyer, a registered document, or a court application specifically addressing the property.

Tamar died suddenly of a stroke fourteen months after separating, with no warning and no time to put anything further in order. Dilshan, named as her executor, discovered within days of starting the estate administration that the title to the house still listed her and Baruch as joint tenants, with no severance ever registered on record anywhere he could find.

The problem

If the joint tenancy had never been severed, the legal consequence was stark and immediate: Baruch, as surviving joint tenant, would own the entire Ottawa house outright the moment Tamar died, by operation of survivorship, and the house would never become part of Tamar's estate at all, no matter what her will said about it. Tamar's will, however clearly and repeatedly it expressed her wishes, has no power to override survivorship on jointly held real estate that remains a true, intact joint tenancy at the exact moment of death. Dilshan would inherit everything else Tamar owned, but not a single dollar of the house she had told him, more than once, she wanted him to eventually have.

Baruch's position, once the estate formally raised the issue through us, was that nothing had legally changed between him and Tamar with respect to the property. No severance document had ever been signed or registered anywhere. No court had ever divided the house or ordered anything with respect to its ownership. In his view, the couple's separation was a personal fact about where they each lived and how they conducted their lives, not a legal one that touched the underlying title, and the house remained his in full the moment Tamar died, exactly as the registered title on file continued to say.

The counter-argument available to the estate rested on a less well-known principle of property law: a joint tenancy can be severed without any formal document at all, if the co-owners' conduct shows a clear, mutual intention to treat their interests in the property as separate rather than unified going forward. Courts have recognized severance by conduct in situations where separated spouses divide their finances, act independently with respect to a shared property, or otherwise behave in a way that is genuinely inconsistent with the survivorship principle a joint tenancy legally depends on. The legal test for this is demanding and highly fact-specific; it is not enough that a couple is simply separated in the ordinary sense. Their actual, documented behaviour toward the specific property in question has to show a mutual treatment of it as two separate shares rather than one combined interest.

Proving that would require reconstructing roughly three years of Tamar and Baruch's financial and practical dealings with the house itself specifically, not just their broader marriage or separation generally, at a moment when the person who best remembered the day-to-day details, Tamar herself, was no longer available to explain any of it firsthand.

What we did

1. Reviewed the separation-era financial records for conduct toward the house specifically. General separation is not enough to sever a joint tenancy; the couple's conduct toward the property itself is what matters. We combed through the accounts Tamar and Baruch had divided to find anything that touched the house's ownership, financing, or expenses, setting aside records that spoke only to their broader personal finances.
2. Found a signed but unregistered separation agreement draft addressing the house. Among Tamar's papers, we located a draft agreement, prepared with a mediator but never formally executed or registered through the courts, in which both spouses had proposed dividing the home's equity fifty-fifty rather than leaving it to survivorship. Though unregistered, this draft was strong, contemporaneous evidence of a genuinely mutual intent to treat their ownership shares as separate going forward.
3. Documented that the couple had stopped paying shared expenses jointly. Bank records showed that after separation, Tamar alone paid the property taxes and insurance on the house, while Baruch reimbursed her for exactly half each time rather than the two of them running the expenses through a shared account, consistent with treating their interests as distinct fifty percent shares rather than a unified joint holding.
4. Obtained an affidavit from the couple's mortgage broker. The broker who had handled the couple's original mortgage confirmed that Tamar had contacted the firm roughly a year before her death to ask about refinancing to buy out Baruch's half interest, a step that only makes sense if she understood the property as already effectively split into two shares rather than a unified joint tenancy.
5. Applied to the court for a declaration that the joint tenancy had been severed. Rather than negotiate informally with Baruch, who was maintaining his full survivorship claim and had little practical incentive to compromise, we brought a formal application asking the court to determine, based on the accumulated conduct evidence, that the joint tenancy had already converted to a tenancy in common before Tamar's death occurred.
6. Managed a serious delay when Dilshan's own health crisis intervened. Roughly five months into the litigation, Dilshan was hospitalized with a cardiac event of his own, unrelated to the estate dispute but serious enough to halt his participation for weeks. We sought and obtained a court-approved adjournment, kept the evidentiary record intact in the meantime, and resumed the application once he had recovered enough to continue.
7. Argued the cumulative pattern, not any single document, at the hearing. No single piece of evidence proved severance on its own. We presented the draft agreement, the expense-splitting pattern, and the refinancing inquiry together as a consistent picture of two people who had already, in practice, stopped treating the house as a unified joint holding rather than two separate shares.

The outcome

The court agreed that the combined evidence established severance by conduct, finding that Tamar and Baruch's course of dealing with the house after separation, particularly the expense-splitting arrangement documented through their bank records and the refinancing inquiry the mortgage broker confirmed, was inconsistent with an intact joint tenancy and showed a mutual, if never formally documented, intention to hold the property as tenants in common rather than as a single combined interest. The joint tenancy was declared severed as of a date roughly a year before Tamar's death, meaning her half-share of the house passed through her estate as an asset like any other, rather than automatically to Baruch by survivorship.

The practical result was that Baruch retained his half of the house outright, which had never actually been in dispute at any point in the proceeding, while Tamar's half, worth roughly four hundred and fifty thousand dollars, became part of her estate and passed to Dilshan under her will, exactly as she had told him, repeatedly and clearly, she intended it to. Baruch did not contest the outcome further once the court's decision came down in writing; the evidentiary record the estate had assembled left little practical room for a further appeal to be worth the additional cost and delay.

Dilshan told us afterward that the delay caused by his own hospitalization had frightened him considerably more than the legal dispute itself ever did, since for several weeks he genuinely did not know whether his health would allow him to see the file through to a conclusion at all. The court's willingness to accommodate that gap without penalty, and the underlying strength of the conduct-based evidence once the application resumed months later, meant the outcome his mother had clearly wanted was ultimately the one the estate secured for him.
