When millions are at stake, a single banking transaction from a decade ago can be the difference between financial security and a devastating loss. In the wake of the BC Court of Appeal’s ruling in Mills v. O’Connor, the rules for protecting excluded property have become a high-stakes obstacle course where only the meticulous survive.
The High Stakes of “Exclusion”
In the quiet, wood-panelled rooms where divorces involving multiple properties are negotiated, one word carries more weight than any other: Exclusion. For a spouse entering a marriage with a significant inheritance, a family business, or a portfolio of pre-marital real estate, the British Columbia Family Law Act offers a promise. It promises that what you brought in, or what was gifted to you alone, remains yours. But as many spouses who had pre-relationship properties are discovering too late, that promise is not a guarantee—it is a challenge.
The recent landmark decision in Mills v. O’Connor has sent shockwaves through the family law community. It serves as a stark reminder that even a $1.85 million inheritance can be whittled down by the courts if it isn’t managed with surgical precision.
If you are a party to a divorce and have significant assets to protect, understanding the “burden of proof”, the “tracing trap”, and the “increase in value rule” is no longer optional. It is the only way to safeguard your legacy.
The Burden of Proof: The Myth of Automatic Protection
There is a dangerous misconception that because the Family Law Act (FLA) defines certain assets as “excluded property”, those assets are automatically shielded from division.
In reality, the law places a burden on the spouse claiming the exclusion.
You must prove, with actual evidence, that the asset exists, that it falls under the definition of excluded property, and—most importantly—that its value can be identified at the time of separation.
The Death of the “Joint Name” Assumption
Historically, many spouses operated under the “Joint Name” assumption. They believed that if an inheritance was used to buy a house in both names, the inheritance remained a 50/50 split of the total value. This was based on the “presumption of advancement”—the legal idea that putting an asset in your spouse’s name was an irrevocable gift.
Amendments to the FLA in May 2023 removed the presumption that if one spouse transfers the title or beneficiary ownership to the other spouse, the excluded property becomes family property. Since May of 2023, if property is excluded from family property, the exclusion applies despite any transfer of legal or beneficial ownership of the property from a spouse to the other spouse.
In other words, the spouse who does not own the exclusion can no longer simply point to the title and say, “Your name and my name are both on it, so it’s 50/50.”
The courts are increasingly moving toward a model where the intent of the transferring spouse is the deciding factor. To claim that a $1 million inheritance has become family property just because it was put into a joint account, the non-owning spouse may now have to prove—with actual evidence—that the transferring spouse truly intended to give up their excluded interest as a gift.
Tracing Is Still Required: Where Value Goes to Die
The most technical and treacherous part of property division is “tracing”. Under Section 85 of the FLA, you are entitled to the value of the excluded property, even if that property has changed form. If you sell an inherited condo and buy a boat, your exclusion “traces” into the boat. Sounds simple? It isn’t.
The “Groceries and Vacations” Trap
Tracing requires that the “value” of the exclusion still exist in an identifiable form at the time of separation. This is where many claimants lose their protection. If you take a $500,000 inheritance and put it into a joint operating account that you also use for daily life, you are walking into a trap. If that money is spent on “consumables”—groceries, family vacations to Hawaii, private school tuition, or car repairs—the exclusion may vanish.
The logic is simple but clear: once the money is spent on something that no longer has value (like a meal or a flight), the “value” of the exclusion no longer exists. You cannot claim an exclusion against an empty bank account. In Mills, the court noted that if funds were used for living expenses rather than being reinvested into a tangible asset like a home or a business, that portion of the exclusion is gone forever.
Pro Rata Tracing: The New Standard
The Court of Appeal in Mills has clarified that pro rata tracing is generally the appropriate approach under the FLA. This means that the exclusion and the family property are treated as proportional partners in the asset. If the house doubles in value, the exclusion grows, but if the house is sold to pay off family debts, the exclusion also shrinks proportionally. You can no longer assume your exclusion is a “fixed sum” that sits at the top of the pile.
The “Increase in Value” Rule: The 50/50 Divide of Success
For those in high-growth markets like Vancouver or Victoria, the “Increase in Value” rule is perhaps the most significant financial factor in a divorce. While Section 85(3) of the FLA protects the original value of your excluded property, Section 84(2)(g) states that any increase in value during the relationship is family property.
For example, if you brought a family business into the marriage worth $5 million, and at the time of divorce, it is worth $15 million, your “exclusion” is $5 million. The remaining $10 million is “family property”, which is generally split 50/50. You may find yourself writing a $5 million cheque to your ex-spouse for the growth of a business they may have never set foot in.
Strategic Protection: How to Survive an Expensive Divorce
1. The Power of Segregation: The single greatest mistake you can make is “co-mingling”. Keep inheritance in a separate account.
2. Forensic Accounting: Use experts to perform the tracing analysis required by the Mills decision.
3. Marriage Agreements: A properly drafted agreement can stipulate that even the increase in value remains excluded.
4. Establishing Intent: Document your intent if you must put an asset in joint names.
Understanding the Impact of Mills v. O’Connor
Property division is a complex puzzle where one missing piece can cost you millions. As Mills v. O’Connor demonstrates, you cannot rely on “fairness” or assumptions. You need a strategy that recognizes the shifting burdens of proof and anticipates the complexities of tracing value through a decade of marriage.
