Dividing RRSPs and Investments in a Divorce: Does Your Spouse Get Half?
If you’re heading into a divorce and you hold investments like RRSPs, TFSAs, or non-registered accounts, one of the first questions you’ll ask is how much of that money your spouse is actually entitled to. Many people assume the answer is a flat 50/50 split. In Alberta, it’s more nuanced than that – and the difference often comes down to a single question: when did you make the investment?
As a Calgary divorce lawyer, Christopher Bungay works primarily with professionals and business owners, spending a lot of time walking clients through exactly this issue. Here’s how Alberta law actually treats investments in a divorce, and what it could mean for your RRSP or portfolio.
The Key Question: When Did You Buy the Investment?
Under Alberta’s Family Property Act, the starting point for dividing any asset – including RRSPs and other investments – is timing. Specifically:
- Investments made during the marriage are generally treated as family property and are presumed to be divided equally between spouses, regardless of whose name is on the account.
- Investments made before the marriage (or before an adult interdependent/common-law relationship began) are generally treated as exempt property and belong to the spouse who owned them going in.
That second point surprises a lot of people, so let’s break down what it actually means in practice.
Example: You Invested Before You Met
Say you were single in 2008 and invested $100,000 in an RRSP. In 2010, you met your future spouse and got married that same year. Sixteen years later, in 2026, you’re getting divorced.
Under Alberta law, that original $100,000 is exempt property. It was yours before the marriage began, so it stays yours after the divorce — your spouse has no claim to that portion.
But here’s the catch: growth on exempt property is not automatically exempt. If that $100,000 grew to $160,000 during the marriage, the $60,000 in growth is treated as family property and is presumed to be split equally. In this example, you would keep $130,000 ($100,000 principal + $30,000 of the growth), and your spouse would be entitled to the other $30,000.
This distinction – original principal versus growth – is one of the most misunderstood parts of Alberta divorce law, and it’s a frequent source of disputes when spouses haven’t kept clear records.
"Traditional" vs. "Modern" Marriages: A Timing Illustration
We often explain this to clients using two common scenarios.
The “traditional” scenario: You married young, before either of you had built up savings. Any RRSPs or investments were purchased after the date of marriage using income earned during the relationship. In this case, the analysis is simple: those investments are family property, and the presumption is an equal division between spouses.
The “modern” scenario: You married later, after your career (and RRSP) were already established. One or both spouses brought pre-existing investments into the marriage. Here, the pre-marriage value of those investments is exempt property, frozen at the value it held on the date of marriage. Only the growth that occurred during the marriage is on the table for division.
Neither scenario is “better”; they simply require a different approach to valuing and dividing the assets, which is exactly why timing and documentation matter so much.
Why Tracing and Documentation Matter
Claiming an exemption on pre-marriage investments isn’t automatic – you need to be able to prove it. Alberta courts require the exempt property to be traceable, meaning you can show a clear paper trail from the original pre-marriage asset to its current form.
Problems arise when:
- Pre-marriage and post-marriage funds have been commingled in the same account without records.
- An RRSP or investment has been moved, converted, or reinvested multiple times over the years.
- No statements or records exist from the date of marriage to establish the original exempt value.
If you can’t trace the exemption, you risk losing it entirely, meaning an asset that should have been protected could end up fully divisible. This is one of the most common (and most avoidable) mistakes we see in high-asset divorces.
Protecting Your Investments Before and During Divorce
A few practical steps can make a significant difference:
- Pull your account statements from the date of marriage (or the start of your relationship) as early as possible.
- Keep pre-marriage and post-marriage contributions separate wherever possible, rather than commingling funds.
- Get a proper valuation of your RRSPs and investment accounts as of the date of marriage and the date of separation.
- Talk to a lawyer before you negotiate anything. Once you agree to a split without understanding the exempt-property calculation, it can be very difficult to unwind.

Dividing RRSPs, investment portfolios, and other financial assets is rarely as simple as “50/50.” Whether your investments were made before or during your marriage can significantly change how much you keep — but only if the exemption is properly identified, calculated, and documented.

Frequently Asked Questions About RRSPs
Does my spouse get half of my RRSP in an Alberta divorce?
Only the portion contributed during the marriage is presumed to be split equally. Contributions made before the marriage are generally exempt, though growth on that amount during the marriage is typically divided.
What is "exempt property" in an Alberta divorce?
Property that one spouse owned before the marriage or relationship began, or received during it as a gift or inheritance from a third party. It’s generally not divided, but growth in its value during the marriage usually is.
How do I prove my RRSP is exempt property?
You need to trace the exempt amount back to its source with account statements or valuations showing the value on the date of marriage.
