Key takeaways
  • A court can set support for a stepparent who stands in the place of a parent, using the amount it considers appropriate.
  • The court looks at the Guidelines and at any other parent's legal duty to support the child.
  • Which law applies depends on whether the couple was married and divorcing, but the table amounts are the same.

You may have helped raise a child for years, then the relationship ended. Now you are wondering whether you can be asked to pay support, or whether you can ask a stepparent for it.

The answer is not automatic in either direction. This article explains the general rule, how the amount is approached, and what usually matters. A lawyer can tell you how it applies to your family.

This article covers the law of Alberta.

When a stepparent can be ordered to pay

The child support rules contain a special provision for a spouse who stands in the place of a parent for a child. In that situation, the court sets the amount it considers appropriate, having regard to the Guidelines and to any other parent's legal duty to support the child.

In plain words, being a stepparent does not by itself decide the question. What matters is whether the stepparent took on the role of a parent. In these cases the court sets the amount it considers appropriate rather than simply applying the plain table amount. How a court views your situation depends on the facts, and a lawyer can help you assess them.

How the amount is approached

For a stepparent, the court is not tied to the plain table amount. It sets what it considers appropriate, while looking at the Guidelines and the legal duty of any other parent.

For a biological or adoptive parent, the starting point is different. The order for a child under the age of majority is the applicable table amount plus any special or extraordinary expenses. Table amounts are driven by the payer's annual income, the number of children and the payer's province.

Which law applies

Divorcing spouses are under the Divorce Act, and the Federal Child Support Guidelines apply unless both are habitually resident in a province designated by order. Unmarried, separated-but-not-divorced and adult interdependent partners proceed under Alberta's Family Law Act and the Alberta Child Support Guidelines.

Alberta's guidelines adopt the federal tables, so the table amounts are the same under both. The stepparent rule is in the federal Guidelines. How the equivalent Alberta wording reads is worth confirming with a lawyer.

Extra expenses and fairness

On a spouse's request, the court may add amounts for child care, the child's share of medical or dental insurance premiums, certain health expenses, extraordinary school or extracurricular costs and post-secondary education. These are generally shared in proportion to each spouse's income, after deducting any contribution from the child.

The court must also take into account subsidies, benefits and tax deductions or credits relating to the expense. If paying the amount would cause undue hardship, the court may award a different amount, though a hardship claim must be denied if the claiming spouse's household would have a higher standard of living than the other household.

What to do next

Either the payor or the recipient may register with MEP, and only one needs to. There must be a filed court order or eligible agreement that sets an enforceable amount. Speak with a lawyer before assuming a stepparent will or will not be responsible.

Frequently asked questions

Is a stepparent automatically responsible for child support in Alberta?

No rule in the Guidelines makes a stepparent responsible simply because of the relationship. The special rule applies where the spouse stands in the place of a parent, and then the court sets the amount it considers appropriate. Whether that applies to you depends on the facts.

Does a stepparent pay the same as a biological parent?

Not necessarily. A stepparent's amount is whatever the court considers appropriate, having regard to the Guidelines and any other parent's legal duty to support the child. A biological parent starts from the table amount.

What documents will I need?

An applicant must include copies of the other spouse's income tax returns for the three most recent years, plus notices of assessment and reassessment. A respondent served with an application must provide the same documents within 30 days if in Canada or the United States, or 60 days elsewhere, unless the court sets another deadline.

Can a stepparent's support be enforced through MEP?

MEP collects court-ordered child, spousal and partner support. It needs a filed order or eligible agreement with an enforceable amount, and either the payor or the recipient must live in Alberta.
