How Alberta Divides Property After Separation

by OP Lawyers LLP – Calgary Law Firm – Ovaici Peydayesh LLP | Oct 7, 2026 | Family Law

When a marriage or common-law relationship ends, one of the most pressing concerns is what will happen to everything the couple has built together: the family home, retirement savings, vehicles, investments, and even a family business.

Alberta has a clear legal framework for dividing property between separating partners, and understanding it can help you set realistic expectations and protect your financial future. At OP Lawyers LLP, our Calgary family lawyers regularly guide clients through property division matters, from straightforward settlements to complex, high-value disputes.

The Law That Governs Property Division in Alberta

In Alberta, the division of property between separating partners is governed by the Family Property Act. The Act came into force on January 1, 2020, replacing the former Matrimonial Property Act. One of the most significant changes was that the law now applies not only to married spouses, but also to Adult Interdependent Partners (AIPs), which is Alberta’s legal term for common-law partners.

Generally, you may be considered an Adult Interdependent Partner if you have:

  • Lived with your partner in a relationship of interdependence for at least three continuous years;
  • Lived together in a relationship of some permanence and have a child together, by birth or adoption; or
  • Entered into a written Adult Interdependent Partner Agreement.

The Act recognizes that both partners contribute to a relationship in many ways, including earning income, raising children, and managing the household. For that reason, property is not simply awarded to whoever’s name is on the title.

The Starting Point: An Equal Split

The core principle of the Family Property Act is that property acquired by either partner during the relationship is presumed to be divided equally. This is often referred to as the “50/50 presumption.”

A home registered in one partner’s name, or a pension earned through one partner’s employment, may still be shared equally if it was acquired during the relationship.

That said, an equal split is a starting point, not a guarantee. Where an equal division would not be fair, the court has discretion to divide property unequally.

What Property Is Protected from Division?

Not everything a person owns is automatically shared. The Family Property Act sets out certain categories of exempt property, including:

Type of PropertyHow the Exemption Works
Property owned before the relationshipThe value of the property at the date of marriage or when the cohabitation began is generally exempt.
Gifts from third partiesGifts received from someone other than your partner are generally exempt.
InheritancesProperty inherited during the relationship is generally exempt.
Personal injury awardsDamages or settlements for personal injury are generally exempt, unless they compensate for a loss to both partners.
Insurance proceedsProceeds are generally exempt, unless they relate to a loss affecting both partners or to property that is itself divisible.

It is important to understand that the exemption typically applies to the value of the property at the relevant date, not to the property as a whole. Any increase in value during the relationship is usually divisible between the partners. For example, if you owned a condominium worth $250,000 when you married and it is worth $400,000 at separation, the $150,000 increase may be shared. The same applies for inheritance. If the value of the inheritance increases during the relationship, it may be subject to division. Our Calgary Family Lawyers, can provide clarity with respect to exemption claims.

The partner claiming an exemption must prove it. This often requires detailed financial records to trace the property back to its original source. Part of the exemption can be lost if exempt funds are mixed with family money, such as depositing an inheritance into a joint account or using it to pay down the mortgage on the family home. A Calgary family lawyer can help you assess whether an exemption still applies and gather the evidence needed to support your claim. This applies to high  net worth family law divisions in Alberta.

When Might Property Be Divided Unequally?

Although the law favours equal sharing, Alberta courts will consider a range of factors when deciding whether an unequal division is more appropriate. These include:

  • The length of the relationship and the length of any period of separation;
  • The financial and non-financial contributions each partner made, including childcare and homemaking;
  • Any written agreements between the partners, such as a prenuptial or cohabitation agreement;
  • Whether one partner wasted, hid, or disposed of family property, known as dissipation;
  • Tax consequences arising from the transfer or sale of property; and
  • Any other circumstance that makes an equal division unfair.

The Family Home and Other Key Assets

For most families, the home is the most valuable asset. Partners may sell it and divide the proceeds, or one partner may buy out the other’s equity. In some cases, the court may grant one partner temporary exclusive possession of the home, particularly where children are involved.

Pensions, RRSPs, investments, and business interests may require professional valuation. Our team at OP Lawyers LLP works with valuators and accountants where needed to ensure these assets are properly assessed.

Don’t Miss the Deadline

Strict limitation periods apply to property claims in Alberta. Generally, married spouses must start a claim within two years of the divorce being granted, and Adult Interdependent Partners must start a claim within two years of the relationship ending. Missing these deadlines can mean losing your claim entirely.

Resolving Property Division Outside of Court

Many separating couples resolve property matters without going to trial. Negotiation, mediation, collaborative family law, and arbitration can all lead to favorable outcomes while saving time, cost, and stress. Any agreement should be based on full and honest financial disclosure. For a property agreement to be binding under the Family Property Act, each partner must also meet certain formal requirements, including acknowledging before a lawyer, separately from the other partner, that they understand the agreement and are signing it freely.
