Do You Automatically Get Half in an Alberta Divorce?

"She gets half of everything." "He is entitled to half my business." Almost everyone arrives at a first consultation carrying some version of the automatic-half assumption, and it is usually wrong in at least one important way. The equal division rule in Alberta is real, but it is a starting presumption with significant carve-outs, not a guarantee. This guide explains what the 50/50 rule actually covers, what falls outside it, and when courts depart from it.

What the Law Actually Says

Alberta's Family Property Act sorts property into three buckets, and the answer to "do I get half" depends entirely on which bucket an asset falls into:

• Family property acquired during the relationship is presumptively divided equally. This is the 50/50 everyone has heard of: the home bought together, savings from employment income, businesses built during the marriage, pensions accrued during the relationship.
• Exempt property is generally not divided at all, at its original value: what each spouse owned before the relationship (at its market value on the date the relationship began), inheritances, gifts from third parties, most personal injury damages, and certain insurance proceeds.
• A middle category is divided by what is just and equitable rather than presumptively equally: chiefly the increase in value of exempt property during the relationship, and property acquired with exempt funds.

So the honest answer to the headline question is: you presumptively get half of the true family property bucket, and how big that bucket is depends on tracing, timing, and evidence. Our guide to what money cannot be touched in a divorce covers the exemptions in detail.

Half of What? Net Value, Not Gross

The division applies to net family property: assets minus the debts attached to them and the costs and taxes built into them. A $900,000 house with a $500,000 mortgage is $400,000 of divisible equity, not $900,000. An RRSP is worth its value net of the tax embedded in it; a business is worth what a purchaser would pay, adjusted for the tax on getting money out. Settlements that equalize against gross values systematically get the math wrong, which is why valuation is often where the real negotiation happens: see how businesses are valued and how pensions and RRSPs are actually divided.

One more timing point that surprises people: in Alberta, family property is generally valued as of the date of trial or the date of the agreement, not the date of separation. If investments grow or a business gains value after you separate but before you settle, that change is usually still on the table.

Exemptions Are Only as Good as Your Tracing

An exemption is not a label that sticks to money forever; it must be traceable into something that still exists. The classic ways exemptions get lost:

• Mixing. An inheritance deposited into a joint account and spent on family living tends to lose its identity.
• The family home trap. Exempt funds put into a jointly owned family home are generally treated as gifted in part: courts commonly find that half the exempt value was shared with the other spouse, so only half the exemption survives, and sometimes less. What happens to the house in an Alberta divorce has its own rules and is where exemption arguments most often die.
• No records. The spouse claiming the exemption must prove it: statements from the start of the relationship, the estate paperwork, the trail from then to now. Without documents, the presumption of equal division fills the gap.

When Courts Divide Unequally

Even within the family property bucket, equal is a presumption, not a command. The Family Property Act lists factors that can justify an unequal division, and in practice the arguments that get traction include:

• Dissipation: one spouse gambling away savings, draining accounts after separation, or deliberately wasting assets. Concealment attracts the same scrutiny, as our article on hidden assets explains.
• Very short relationships, where a full equal split of everything acquired would be a windfall.
• Debts and liabilities incurred recklessly or for purely personal purposes.
• Agreements: a properly executed prenuptial or cohabitation agreement with disclosure and independent legal advice can replace the statutory scheme altogether.

Unequal division is the exception, not the rule, and courts do not adjust the split to punish bad behaviour in the marriage generally. Adultery, for example, is not a property factor; wasting family money on the affair can be.

Nothing Happens Automatically

The word "automatically" fails in a second way: property division does not happen by itself. It happens when the spouses sign a binding agreement, usually a separation agreement with disclosure and independent legal advice, or when a court orders it. Until then, title mostly governs day to day, and limitation periods matter: for married spouses the final deadline generally falls two years after the divorce judgment (though some standalone claim routes expire two years after separation), while for adult interdependent partners the clock generally runs from the date they became former adult interdependent partners, which for partners who simply separate is generally about one year after the separation itself. For common-law partners in particular, separating and doing nothing can quietly extinguish rights.

Common-law couples should note that since 2020 the Family Property Act applies to adult interdependent partners as defined by the Adult Interdependent Relationships Act, so the same presumptions, exemptions, and deadlines are in play. Our guide to common-law separation covers the differences that remain.

Finally, keep property and support separate in your head: dividing property equally does not decide spousal support or child support. Those are calculated from income and need, and they interact with the property split rather than being replaced by it.
