In Alberta, a shared parenting arrangement legally requires the child to spend at least 40% of their time with each parent over the course of a year. Reaching this 40% threshold triggers Section 9 of the Federal Child Support Guidelines, meaning child support is typically calculated by offsetting both parents’ incomes.
When separating couples focus on what is best for their kids, shared parenting is often the goal. If you live in Lethbridge, Red Deer, or Edmonton, understanding the legal requirements for shared parenting arrangements in Alberta is essential for planning your family’s future. The legal terminology has shifted away from the old American-style term “custody,” moving towards the more cooperative concepts of “parenting time” and “decision-making responsibility.”
For an arrangement to be legally recognized as “shared” (particularly for financial purposes), the courts look at hard mathematics. 📈 The most critical metric is the 40% rule. If a parent cares for the child for less than 40% of the year, they are generally considered the access parent, and they must pay full table child support based on their gross income. Once the 40% threshold is crossed, the financial rules completely change.
Because calculating time and negotiating fair support can become highly adversarial, retaining professional counsel is a wise investment. We strongly recommend searching our directory to find a local family lawyer or law firm. They can help you structure a parenting schedule that works for your children while ensuring your financial obligations are fair and legally sound.
Step-by-Step Process for Establishing Shared Parenting
Creating a successful shared parenting plan requires careful scheduling and full financial transparency. To ensure your arrangement meets the strict criteria set by the Alberta Court of King’s Bench, most families follow these standard steps.
Step 1: Calculate the 40% Time Threshold
The absolute first step is mathematically proving the 40% threshold. 📅 In a standard 365-day year, 40% equals exactly 146 days. Courts usually count overnights to determine this, but if a parent spends significant daytime hours feeding, transporting, and caring for the child, hours can sometimes be calculated to meet the threshold. You must create a clear calendar schedule proving this time.
Step 2: Exchange Income Information
Once you confirm the schedule qualifies as shared parenting, both parents must fully disclose their incomes. Unlike a sole parenting situation where only the paying parent needs to show income, shared parenting requires both parties to provide their most recent CRA notices of assessment, tax returns, and current pay stubs.
Step 3: Calculate the Set-off Child Support
Next, you apply Section 9 of the Federal Child Support Guidelines. 💰 You look up what Parent A would pay Parent B based on Parent A’s income, and what Parent B would pay Parent A based on Parent B’s income. You then subtract the lower amount from the higher amount. The parent with the higher income pays the “set-off” difference to the lower-income parent.
Step 4: Draft and File a Consent Order
Once you agree on the schedule and the set-off support amount, a lawyer must draft a formal agreement. To make it legally binding and enforceable by the Maintenance Enforcement Program (MEP), you should file it as a Consent Order at the local Court of King’s Bench.
How Much Does it Cost in Alberta?
Establishing shared parenting is an investment in your child’s well-being, but it does come with legal costs. Here is what you can generally expect to pay in Alberta as of March 2026:
- Court Filing Fees: If you are filing a new Family Law Act application or a standard family application in court, the filing fee (updated in August 2025) is $100 CAD. However, if you already have an active court file, submitting a Desk Consent Order is completely free ($0 CAD).
- CRA Tax Records: $0 CAD to log into your CRA portal and download your notices of assessment.
- Family Mediation: Typically $200 to $500 CAD per hour. A neutral mediator can help parents agree on a 50/50 or 60/40 schedule without fighting in court.
- Lawyer Retainers: For drafting a customized shared parenting agreement, expect to pay between $2,000 and $4,500 CAD. If the matter is contested and goes to trial, costs can easily exceed $15,000 CAD.
It is important to remember that child support is the right of the child, not the parent. 💵 You cannot sign a contract completely waiving child support just because you have a 50/50 time split. If there is a massive difference in your incomes, the court will demand a set-off payment to ensure the child has a similar standard of living in both homes.
| Parenting Time Split | Child Support Calculation Method | Who Must Disclose Income? |
|---|---|---|
| Primary (e.g., 80/20) | Full Table Amount | Only the paying parent (the 20% parent) |
| Shared (e.g., 60/40) | Set-off / Section 9 Guidelines | Both parents must disclose |
| Equal (50/50) | Set-off / Section 9 Guidelines | Both parents must disclose |
How Long Does the Process Take?
The timeline to finalize a shared parenting arrangement depends heavily on the level of conflict between you and your ex-partner. If both parents are amicable and agree that a 50/50 schedule is in the child’s best interests, a law firm can draft a binding parenting plan and Consent Order in just 2 to 4 weeks.
If there is a disagreement over whether the 40% threshold has actually been met, negotiations can take much longer. 📅 Gathering evidence, exchanging schedules, and attending mediation to hammer out the exact hours and days can stretch the process to 3 to 6 months.
If one parent stubbornly refuses to share parenting time, you will have to initiate court proceedings. Note that under the Court of King’s Bench’s mandatory Family Focused Protocol (FFP) (launched January 2, 2026), you cannot simply have a judge hear your case right away. You are legally required to complete at least one hour of family mediation or an ADR process before a judge can hear your application. Litigating a contested parenting dispute at the Court of King’s Bench can take 12 to 24 months before you get a trial date and a binding decision.
Frequently Asked Questions (FAQ)
Does a 50/50 time split mean nobody pays child support?
No. Even with a perfect 50/50 time split, child support is almost always payable if the parents have different incomes. The higher-earning parent will pay a set-off amount to the lower-earning parent to balance the child’s standard of living.
How do we calculate special or extraordinary expenses?
Special expenses, known as Section 7 expenses (like braces, tutoring, or competitive sports), are handled separately from basic monthly child support. In a shared parenting arrangement, these costs are typically divided proportionally based on each parent’s gross income.
What happens if my ex drops below 40% time?
If the scheduled 40% time is not actually happening in reality (e.g., they consistently miss their weekends), you can apply to the Court of King’s Bench to cancel the shared status. Your ex would then be forced to pay the full, higher table amount for child support.
Do we have to share decision-making responsibility too?
Not necessarily. While shared parenting time (physical care) and joint decision-making responsibility (legal choices about health, education, and religion) often go together, a judge can order shared time but give one parent the sole authority to make major decisions if the parents cannot communicate.
Can the set-off support amount be adjusted?
Yes. Under Section 9, a judge has the discretion to adjust the set-off amount if strictly applying the mathematical formula would cause significant financial hardship to one parent, though the standard set-off is the starting point for almost all negotiations.
