Part 2 of 2: Inheritance, Claims, and the Traps in the Timing
In Part 1 we dealt with the threshold question: who is an adult interdependent partner (“AIP”) under the Adult Interdependent Relationships Act, SA 2002, c A-4.5 (“AIRA”), and when that status begins and ends. Three points from that post carry the weight of this one:
- You can acquire the status without signing anything — three years of living together in a relationship of interdependence is enough (AIRA s 3(1)(a)(i)), and it need not be a romantic relationship.
- A married but separated person can have an AIP while remaining legally married (AIRA s 5(2)) — so two people can have claims at once.
- Separation does not end the status. Absent a written agreement or a declaration of irreconcilability, your former partner remains your AIP for one year and a day (AIRA s 10(1)(b)).
Now the consequences. Alberta’s succession legislation treats a surviving AIP, in most respects, exactly as it treats a surviving spouse.
