How Do I End an Adult Interdependent Relationship in Alberta?

This answer covers the law of Alberta.

You do not need to file anything in court to end an adult interdependent relationship in Alberta, and there is no divorce for it. The relationship ends when one of the events in the Adult Interdependent Relationships Act happens, and the earliest one sets the end date.

Those events are a written agreement to live separate and apart without possibility of reconciliation, or living separate and apart for more than one year with one or both of you intending the relationship not to continue. It also ends if you marry each other or one of you marries someone else, or if a declaration of irreconcilability is made under the Family Law Act. If you qualified through the 3-year or child route, entering an adult interdependent partner agreement with someone else also ends it. A single period of not more than 90 days with reconciliation as its main purpose does not interrupt a separation.

The end date matters because a property claim generally must start within 2 years of when you knew you became former partners, or as little as one year after a transfer made to defeat the claim. A separation agreement can cover parenting time, child support, spousal support and property division, and Alberta.ca recommends speaking with a lawyer.
