When deciding a parenting dispute in Calgary, a judge doesn't focus on what's fair to each parent. Instead, Alberta courts apply one overriding legal principle: the best interests of the child. Every decision about parenting time and decision-making responsibility is assessed through that lens.
Understanding how this legal test works and which factors courts consider most important can help parents approach their case with realistic expectations and stronger preparation.
Alberta courts decide parenting arrangements using the best interests of the child test under the Divorce Act and Alberta's Family Law Act. Judges weigh the child's needs, each parent's caregiving history, the child's own views, family violence, stability, and each parent's willingness to support the child's relationship with the other parent. No single factor decides a case on its own.
The best-interests test looks at the whole picture of a child's life, not one deciding factor:
A child custody lawyer Calgary parents work with builds a case around these factors specifically, not around a general argument about which parent deserves more time.
Alberta courts don't start from an assumption that time should split evenly, or that one parent has a natural advantage. Section 16 of the Divorce Act and Alberta's Family Law Act both direct judges to decide based on what serves the specific child in front of them, considering that child's circumstances rather than a general rule applied to every family. This is why two cases with similar facts can end in different arrangements: the test is about this child, not a formula.
A younger child's needs, routine, feeding, sleep schedule, proximity to a primary caregiver, differ from a teenager's, who may need more say in where they spend time and how their schedule accommodates school and social life. Courts adjust how much weight they give a child's stated preference based on age and maturity, giving more weight to a mature teenager's view than a young child's.
Courts look closely at who has handled day-to-day caregiving before the dispute arose: school drop-offs, medical appointments, bedtime routines, and daily decisions. A parent who has been consistently involved in these responsibilities tends to be viewed as continuing that role, while a parent seeking a significant increase in time from a previously limited role needs to show why that change serves the child now.
A child's own perspective is a factor Alberta courts consider, though not by asking a child to choose between parents directly. Depending on the case, a child's views can come through a parenting assessment, a judge's interview, or evidence presented by a parent. Younger children's preferences carry less independent weight than a mature teenager's clearly reasoned views.
Where family violence is part of the case, it directly affects the arrangement a court will order. Judges consider the nature and severity of the violence, its impact on the child, and whether it affects a parent's ability to care for the child safely. This can result in supervised parenting time, restricted decision-making responsibility, or other protective terms built into the order.
Courts pay attention to how each parent talks about and treats the other parent's role in the child's life. A parent who actively supports the child's relationship with the other parent, facilitating contact, communicating respectfully, avoiding put-downs, tends to be viewed favourably. A parent who undermines that relationship, even without an overt conflict, can see that behaviour weighed against them.
Uprooting a child from their school, neighbourhood, and existing routine carries real weight in a court's analysis. This doesn't mean the status quo always wins, but a parent proposing a change to a child's stable circumstances needs a clear reason the change serves the child, not just the parent's preference.
Married parents going through a divorce fall under the federal Divorce Act; unmarried parents fall under Alberta's Family Law Act. Both apply the same best-interests test and weigh the same core factors. The main practical difference is which court and which statute technically governs the case, not how the decision itself gets made.
Most parenting disputes don't reach a judge. They resolve through negotiation between lawyers, mediation, or a parenting assessment that brings a neutral professional's evaluation into the picture before anything reaches court. A parenting assessment can carry significant weight when parents' accounts of caregiving history or the child's needs differ substantially. Court becomes necessary when these earlier options don't produce an agreement both parents can accept.
| Factor | What the Court Looks At |
| Age and needs | How the child's stage of development shapes what arrangement fits |
| Caregiving history | Which parent has handled day-to-day care and responsibilities |
| Child's views | Weighed by age and maturity, not treated as a direct choice |
| Family violence | Nature, severity, and impact on the child's safety |
| Support for the other parent's role | Whether a parent facilitates or undermines that relationship |
| Stability | The disruption a proposed change would cause to school, home, and routine |
| Cooperation | Each parent's ability to communicate on the child's behalf |
THEBIL Family Law prepares parenting cases by building evidence around the specific factors a judge will weigh, caregiving history, stability, the child's needs, rather than presenting a general argument about fairness. A child custody lawyer Calgary parents consult early can identify which factors are strongest in their situation and build the case accordingly.

Using the best interests of the child test, weighing factors such as the child's age and needs, each parent's caregiving history, the child's own views, family violence, stability, and each parent's willingness to support the other parent's relationship with the child.
No. Courts start from what serves the specific child, not an assumed equal split. Some cases result in equal time; many don't, depending on the family's circumstances.
Not directly. A child's views are one factor among several, weighed by age and maturity, and courts don't ask a child to choose between parents outright.
Not on its own. Income factors into child support calculations, but parenting time and decision-making responsibility are decided based on the child's best interests.
Courts consider the nature, severity, and impact of the violence on the child, which can lead to supervised time, restricted decision-making, or other protective terms.
The applicable law differs, the Divorce Act for married parents and Alberta's Family Law Act for unmarried parents, but both apply the same best-interests test and factors.
This is often where a parenting assessment or documented evidence, such as school and medical records, becomes important in showing the court an accurate picture.
Not automatically. Courts look at the overall caregiving picture and a parent's plan for the child's care, not simply whether a parent works.
Yes. THEBIL Family Law reviews each family's specific circumstances to identify which best-interests factors are strongest and how to present them effectively.
