When parents separate or divorce, ensuring that their children continue to receive appropriate financial support is an important part of the process. Child support helps cover the costs of raising children, including housing, food, clothing, education, and other everyday needs.

In Alberta, child support is governed by applicable federal and provincial laws and guidelines. The amount payable depends on factors such as parental income, the number of children, and the parenting arrangement. Understanding how child support works can help parents make informed decisions and protect their children's interests.

This guide explains the main rules surrounding child support in Alberta, how payments are calculated, and what parents can do if circumstances change.

What Is Child Support in Alberta?

Child support is financial assistance paid by one parent to help meet the costs of raising a child following separation or divorce. It is intended for the benefit of the child, rather than as financial support for the other parent.

Both parents generally have a legal responsibility to support their children, even if the children primarily live with one parent. The parent who has less parenting time will often pay support to the other parent, although the amount depends on the applicable guidelines and circumstances.

Child support may be established through a written agreement, a court order, or an administrative process where available.

Who Is Entitled to Child Support?

Children may be entitled to support when their parents separate or divorce. Under the federal Divorce Act, child support may be payable for a child of the marriage, including certain adult children who remain dependent because of illness, disability, or other circumstances such as pursuing education.

For parents who were never married, provincial legislation may apply, depending on their circumstances.

Child support does not automatically end when a child turns 18. The child's age, education, financial independence, and other relevant circumstances may affect whether support continues.

Parents should obtain legal advice before stopping payments, particularly when a court order or formal agreement is in place.

How Is Child Support Calculated in Alberta?

Child support is generally calculated using the applicable Child Support Guidelines. For many cases, the calculation begins with the paying parent's annual income, the number of children entitled to support, and the relevant guideline table amount.

The federal guidelines generally apply to divorcing spouses, while Alberta's guidelines may apply to other eligible cases. The applicable rules should be confirmed for the specific situation.

For example, a parent supporting two children may pay a different amount from a parent supporting one child with the same income. The amount can also be affected by special expenses or shared parenting arrangements.

Parents can use the relevant official child support tables or calculator as a starting point. However, the result should be checked against the applicable law and the facts of the case.

What Are Special or Extraordinary Expenses?

In addition to basic monthly child support, parents may have to contribute to certain expenses under section 7 of the applicable guidelines. These are commonly known as special or extraordinary expenses.

They may include:

  • Childcare expenses required because of a parent's employment, education, or training.
  • A child's medical or dental insurance premiums and certain uninsured healthcare expenses.
  • Extraordinary expenses for primary or secondary education.
  • Post-secondary education expenses.
  • Extraordinary extracurricular activity expenses.

Not every activity or additional cost automatically qualifies. The court or parents may need to consider whether an expense is necessary, reasonable, and affordable in light of the family's financial circumstances.

These expenses are generally shared according to the parents' respective incomes, after accounting for any applicable contribution from the child or other relevant adjustments.

Does Shared Parenting Affect Child Support?

Yes. Parenting arrangements can affect how child support is calculated.

When a child spends substantial time with each parent, the applicable shared-parenting provisions may need to be considered. Under the federal guidelines, the shared-parenting rule generally applies when each parent exercises at least 40% of parenting time over the course of a year.

However, reaching the 40% threshold does not automatically mean that no child support is payable. The calculation may consider each parent's table amount, the increased costs of shared parenting, and the financial circumstances of both households.

Parents should avoid assuming that equal parenting time necessarily means equal financial responsibility or that support payments automatically cancel each other out.

Can Child Support Be Changed?

Child support may be changed when there is a qualifying change in circumstances. Examples include:

  • A significant change in either parent's income.
  • A change in the number of children entitled to support.
  • A change in the parenting arrangement.
  • A change in a child's educational or healthcare needs.
  • A change in eligibility for ongoing support.

Depending on the existing arrangement, parents may be able to agree to an updated amount. If they cannot agree, an application to the court or another available legal process may be necessary.

Parents should document income changes and keep relevant financial records. Do not assume that a payment amount changes automatically simply because one parent's circumstances have changed.

What Happens If a Parent Does Not Pay Child Support?

Failure to pay court-ordered child support can lead to enforcement action. In Alberta, the Maintenance Enforcement Program may assist with collecting eligible support payments under an enforceable order or agreement.

Depending on the circumstances and applicable law, enforcement measures may include deductions from income, collection from certain funds, or other permitted actions.

If a paying parent cannot afford the existing amount, they should seek advice about applying for a variation rather than simply stopping payments. Likewise, a parent who is not receiving support may wish to explore the available enforcement options.

Do You Need a Child Support Lawyer in Alberta?

Some parents can agree on child support without going to court. However, legal advice may be particularly helpful where income is disputed, one parent is self-employed, special expenses are significant, parenting time is contested, or a parent is seeking to change an existing order.

A family lawyer can explain which guidelines apply, help review financial information, and assist with negotiating an agreement or presenting an application to the court.

Conclusion

Child support in Alberta helps ensure that children continue to receive financial support when their parents separate or divorce. The amount depends on the applicable guidelines, parental income, the number of children, parenting arrangements, and any qualifying additional expenses.

Understanding the rules can help parents make informed decisions and reduce avoidable disputes. If you are establishing, changing, or enforcing child support, legal advice can help you understand the options available under Alberta law.
