Sole vs Joint vs Shared Custody in Nunavut: How the Court Decides

The old labels — sole custody, joint custody — still circulate in everyday conversation and even on Nunavut court forms. But since March 2021, the Divorce Act replaced them with two separate concepts: decision-making responsibility (who makes major life decisions) and parenting time (where the child physically lives). Understanding the distinction matters because judges evaluate each one independently.

Decision-Making Responsibility

Sole decision-making responsibility means one parent has the final say on major decisions about health, education, religious upbringing, language, and significant extracurricular activities. The other parent still has parenting time but cannot override these decisions.

Joint decision-making responsibility requires both parents to consult and agree on major decisions. If you cannot agree, you may need mediation or a court application to break the deadlock.

Split decision-making divides authority by subject — one parent handles medical decisions, the other manages education. This is less common but can work when parents cooperate on some topics but clash on others.

Parenting Time Arrangements

Primary residence with regular parenting time means the child lives mainly with one parent. The other parent has scheduled time — often alternating weekends and a weekday evening. This works well for high-conflict situations or when parents live in different Nunavut communities where frequent handovers are impractical.

Shared parenting time (50/50 or near-equal) means the child spends roughly equal time with each parent. Common patterns include alternating weeks, or a 5-2-2-5 rotation where each parent always has the same weekdays and weekends alternate. This requires parents to live in the same community — weekly rotations are physically impossible between fly-in hamlets.

The Best-Interests Factors

The Nunavut Court of Justice applies the best-interests standard from both the Divorce Act (Section 16) and the Children's Law Act (Section 17). The child's physical, emotional, and psychological safety always comes first. Beyond safety, judges weigh:

• The child's relationship with each parent, siblings, and grandparents
• Each parent's historical caregiving role during the relationship
• Each parent's willingness to support the child's relationship with the other parent
• The child's views and preferences, weighted by age and maturity
• Cultural, linguistic, and spiritual heritage — with explicit protection for Inuit family structures under Section 17(1) of the Children's Law Act
• Any history of family violence, which heavily disfavours shared arrangements

There is no presumption of 50/50 in Nunavut. The court tailors the arrangement to the child's specific needs.

The 40% Threshold and Child Support

The parenting time split directly affects child support calculations. If a child spends at least 40% of the year (146+ days) with each parent, Section 9 of the Federal Child Support Guidelines applies. Instead of one parent paying the full table amount, the court uses a set-off calculation that factors in both parents' incomes and the increased costs of maintaining two full households.

Below the 40% threshold, the parent with less time pays the straight table amount based on their gross income.

What Arrangement Works for Your Family?

The right arrangement depends on your specific situation — geography, work schedules, the child's age, and your ability to communicate with your co-parent.
