Common-Law Separation Agreements: Your Guide to Moving Forward in Alberta

When a common-law relationship ends, the emotional impact can be just as significant as a divorce. In Alberta, these relationships are legally known as Adult Interdependent Relationships (AIRs), and the partners are called Adult Interdependent Partners (AIPs).
A well-prepared common-law separation agreement helps you understand your rights and responsibilities, reduce conflict, and create a clear plan for the future. It’s especially important now that, in many cases, AIPs are treated similarly to married spouses when it comes to dividing property.
How Property Division Works for AIPs in Alberta
For most people separating today as AIPs, the Family Property Act (FPA) is the starting point.
If you separated, or are now separating, as AIPs on or after January 1, 2020, the FPA generally treats you similarly to married spouses. In many cases, there is a presumption that:
- Most property acquired during the relationship will be shared, often on an equal or near-equal basis, unless you agree otherwise or a different division is justified.
- A properly drafted separation agreement can set out how you will divide property and debt, instead of leaving those decisions to the court.
Earlier separations, or situations where the parties did not qualify as AIPs, may still be dealt with under older, more complex common law principles.
What Your Separation Agreement Can Cover
A common-law separation agreement for AIPs typically addresses:
- Property and debts: Who will keep the home, vehicles, investments, and other major assets, and how liabilities will be shared or paid out.
- Spousal or partner support: Whether support will be paid, in what amount, and for how long, recognizing that the law allows for changes if circumstances shift.
- Children’s issues: How decision-making, parenting time, and child support will be handled, always subject ot the children’s best interests and current legislation.
Property terms can often be made binding if the agreement meets the FPA requirements. Support and parenting terms may need to change over time as circumstances and children’s needs evolve.
What Makes a Property Agreement Enforceable?
For property division terms to be enforceable under the FPA, the law requires more than just signatures. In particular:
- Each partner must acknowledge, in writing and separately from the other, that they both understand the nature and effect of the agreement and that they understand that they’re able to make a claim under the FPA and intend to give up those rights as needed to give effect to the agreement. They must also acknowledge that they are signing freely and voluntarily.
- Each acknowledgement must be given in front of that partner’s own lawyer, not with the same lawyer acting for both.
Why Independent Legal Advice and Disclosure Matter
To protect yourself, it’s important to have:
- Full financial disclosure: A complete picture of assets, debts, and income for both partners.
- Tailored legal advice: A lawyer who reviews disclosure, explains the relevant law, and helps you understand whether the agreement is reasonable in your circumstances.
There are also limitation periods that apply. For example, an application for a property order under the FPA usually must be started within two years of when you know, or ought to have known, that you became a former AIP.
