1. The Rule Isn’t Contribution-Based — and That’s On Purpose
If property division were simply 50/50, who would feel it worked in their favour, and who would feel shortchanged? It’s tempting to assume the answer tracks who put more money, time, or work into the relationship — the less active spouse pushing hard for an even split, and the more active one pushing back against it.
Here’s the part that surprises most people: BC’s Family Law Act was deliberately built to ignore that entire argument.
The rule isn’t activity-based — and that’s on purpose
Unlike some approaches to property division, BC doesn’t ask who earned more, who did more housework, or who stayed home with the kids. Family property acquired or grown during the relationship is generally split equally, regardless of how financially or practically active each spouse was. This isn’t an oversight — it’s the point. An activity-based system invites exactly the kind of dispute where every dollar earned, every load of laundry, and every parent-teacher conference becomes evidence in a ledger nobody can ever fully settle. BC’s equal-division default exists specifically to take that fight off the table.
So if activity level doesn’t decide it, what actually does?
2. What actually can make 50/50 unfair
The law does allow for an unequal division, but only where an even split would be “significantly unfair” under section 95 of the Family Law Act — a high bar, and a narrow one. What actually gets weighed isn’t who did more, but specific, provable circumstances such as:
A short relationship, where splitting long-held, pre-relationship assets equally would produce a clearly disproportionate result One spouse dissipating family assets — through gambling, reckless cryptocurrency speculation, or a pattern of business failures rooted in provable reckless conduct One spouse hiding assets or failing to disclose honestly Significant debt taken on by one spouse without the other’s knowledge or benefit
Notice what isn’t on that list: simply earning more, or being more active in day-to-day labour. Those facts might feel deeply relevant to the spouse living them, but they generally don’t move the legal needle on their own.
3. What you bring in matters — but through a different door
Separately from the “significantly unfair” question, BC law also excludes certain property from division in the first place — most commonly, what either spouse owned before the relationship began. This isn’t about fairness weighing; it’s a different mechanism entirely. What’s excluded stays excluded (subject to sharing any increase in its value during the relationship), regardless of how the rest of the property gets split.
This is where a prior agreement matters most. Whether there’s a marriage or cohabitation agreement in place can change what counts as family property entirely, before any 50/50 or unequal-division question is ever reached.
4. Where a prenup carries real weight
I’ve seen this come up in a specific, recurring situation: one spouse is a shareholder in a family-held company, and the family wants the incoming spouse to sign an agreement excluding those shares from family property before the marriage. The reasoning is usually straightforward — protecting the company’s ownership and decision-making from being affected by a future separation. It’s a legitimate use of a marriage agreement, and it’s worth having that conversation early, well before a wedding date puts pressure on the timeline.
So — is 50/50 fair?
Sometimes, yes, precisely as written. Sometimes, the honest answer is that “fair” and “equal” pull in different directions, and the law makes room for that too — just not for the reasons most people initially assume. The question worth asking isn’t “who was more active,” but: how long was the relationship, what did each of you bring in at the start, was there dissipation or non-disclosure, and is there an agreement already governing some of this? Those are the facts that actually decide the outcome — not the ledger either spouse has been keeping in their head.
