Key takeaways
  • Alberta does not require a separation agreement, though the government recommends speaking to a lawyer if you write one.
  • Without an agreement, the Family Law Act, the Divorce Act and the Family Property Act decide which rules apply to you.
  • Partners can opt out of the default property division by drafting their own agreement, and the Family Property Act sets out what makes a written property agreement compliant.

You have separated, and someone has told you that you need a separation agreement. Or someone has said you do not need anything. Both can sound right, which makes it hard to know where you stand.

This article explains what a separation agreement is, what happens if you do not have one, and what other options exist. It is general information about Alberta law, not advice on your own situation.

This article covers the law of Alberta.

Is a separation agreement required in Alberta?

No. Alberta does not require a separation agreement. The government says you can write one yourselves, but it recommends speaking to a lawyer.

It also helps to know that Canada has no formal status called legal separation. Alberta's government describes married spouses or adult interdependent partners as separated when they end the relationship and live apart. Under the Divorce Act, spouses are deemed to have lived separate and apart for any period during which they lived apart and either of them intended to live separate and apart from the other. If you still share a home, how this applies depends on the facts, and the evidence is a matter for the court. Whether and how separation affects your rights depends on your situation, so it is worth confirming with a lawyer.

What a separation agreement usually covers

A separation agreement is a contract between people who are separating or divorcing. Common topics include:

Courts can review the parenting and support parts of an agreement, so do not assume those terms will be enforced exactly as written. A lawyer can explain how this applies to your terms.

What applies if you have no agreement

Without an agreement, married spouses who separate but do not divorce are under the Family Law Act rules. Spouses who divorce are under the federal Divorce Act. Property is then divided under the Family Property Act or by a court.

So the law still gives you a framework. What you lose is the chance to shape the result together. Instead, a court may decide if you cannot agree.

Other routes instead of a legal separation

Instead of a legal separation status, you can use a separation agreement, Family Law Act court orders (such as parenting, support or exclusive possession), Family Property Act orders for property, or a divorce under the Divorce Act.

If you want to resolve things outside court, the Family resolution hub and Family Justice Strategy are government options for parenting, child support or divorce matters. Family mediation and parenting-after-separation programs are also offered. The mandatory requirements package says all parties should consider independent legal advice throughout the process, including before any alternative dispute resolution.

Property agreements and the two-year deadline

Partners can opt out of the default Family Property Act division by drafting their own agreement to divide property differently, and Alberta advises contacting a lawyer about this. For the agreement to count as a compliant written agreement, each party must acknowledge in writing, apart from the other party, that they understand the agreement and the future property claims they give up, and that they sign it freely and without compulsion. That acknowledgement must be made before a lawyer other than the lawyer acting for the other party.

Deadlines are also part of the picture. A property proceeding between spouses on separation may be started within 2 years after the date the spouses separated. Where there is a divorce, the limit is 2 years after the date of the decree nisi, declaration or judgment. Adult interdependent partners must start within 2 years after they first knew, or ought to have known, they had become former adult interdependent partners, and the changes giving them the same property division rules as married spouses only apply to couples who separated on or after January 1, 2020. Because the starting point can differ, it is worth confirming your own dates with a lawyer.

What to do next

Frequently asked questions

Can we write our own separation agreement?

Yes. Alberta says you can write one yourselves, though it recommends speaking to a lawyer. If it deals with property, the Family Property Act sets out what makes a written property agreement compliant, including a written acknowledgement made before a lawyer who is not acting for the other party.

Do we need to notarize a property agreement?

Notarization is not the stated requirement. For property, each party must acknowledge the agreement in writing, apart from the other, before a lawyer who is not acting for the other party.

What if we never sign an agreement?

The Family Law Act, the Divorce Act and the Family Property Act still apply depending on your situation, and a court can decide matters you cannot settle.

Does the two-year property deadline change if we have an agreement?

The Family Property Act sets different start points: 2 years after separation for spouses, 2 years after the decree nisi, declaration or judgment where there is a divorce, and 2 years from when adult interdependent partners first knew, or ought to have known, they became former partners. How an agreement affects these deadlines depends on your situation, so it is worth confirming with a lawyer.
