Answer: Child support in Alberta does not automatically end when a child turns 18. Under both the federal Divorce Act, R.S.C. 1985, c. 3 (2nd Supp.), s. 2(1) and the provincial Family Law Act, SA 2003, c F-4.5, support continues for any child who is unable to withdraw from a parent's charge by reason of illness, disability, full-time enrollment in post-secondary education, or other cause. The Alberta Maintenance Enforcement Program (MEP) enforces child support orders for adult children up to age 22 if they remain full-time students. Alberta amended its Family Law Act in December 2018 to remove all age caps for eligible adult children, meaning support obligations can extend indefinitely in cases involving disability or chronic illness.

What Age Does Child Support End in Alberta?
Child support in Alberta does not end at a fixed age. Under the Divorce Act, R.S.C. 1985, c. 3 (2nd Supp.), s. 2(1), a "child of the marriage" includes any person under the age of majority (18 in Alberta) who has not withdrawn from a parent's charge, and any person aged 18 or older who remains unable to withdraw from a parent's charge due to illness, disability, or other cause. Alberta courts interpret "other cause" broadly to include full-time post-secondary enrollment, making the question of when does child support end Alberta a fact-specific inquiry rather than a simple age calculation.
The provincial Family Law Act, SA 2003, c F-4.5 mirrors this approach. Following amendments that took effect in December 2018, Alberta eliminated its previous age cap for adult child support entirely. Before 2018, the Family Law Act limited support for full-time students to the 18-to-22 age range. The current legislation contains no maximum age threshold for eligible adult children, aligning provincial law with the federal Divorce Act's open-ended framework.
Alberta courts apply a two-part test to determine whether an adult child qualifies for continued support. First, the child must be "unable to withdraw" from the parent's charge. Second, that inability must arise from a recognized cause — illness, disability, full-time student status, or another qualifying circumstance. The burden of proving both elements rests with the party claiming continued support, typically the parent with primary parenting time or the adult child themselves.
How Post-Secondary Education Extends Child Support in Alberta
Full-time post-secondary enrollment is the most common reason child support continues past age 18 in Alberta. Alberta courts routinely hold that a child attending university, college, or vocational training on a full-time basis remains a "child of the marriage" under the Divorce Act, s. 2(1)(b) and a dependent adult child under the Family Law Act. The Maintenance Enforcement Program enforces support for full-time students until the child reaches age 22, completes a first post-secondary degree, diploma, or certificate, or ceases to be a full-time student — whichever occurs first.
Alberta courts consider several factors when determining whether post-secondary support is warranted. The child's academic program must be reasonable and pursued in good faith. A child who repeatedly fails courses, changes programs without a clear direction, or takes extended breaks from studies may lose entitlement. Courts also examine whether the child has made reasonable efforts to contribute to their own expenses through summer employment or part-time work during the academic year.
The amount of child support during post-secondary studies often differs from the standard table amount calculated under the Alberta Child Support Guidelines, Alta. Reg. 147/2005. Courts may apply a "set-off" approach where both parents contribute proportionally to the child's educational expenses based on their respective incomes. Section 7 of the Federal Child Support Guidelines covers "special or extraordinary expenses," which include post-secondary tuition, textbooks, and reasonable living costs. These expenses are typically shared between parents in proportion to their incomes after accounting for any contribution from the child, scholarships, or student loans.
When Child Support Ends Automatically in Alberta
Child support ends automatically in Alberta when a child under 18 marries, joins the Canadian Armed Forces, or otherwise demonstrates complete financial independence from both parents. For children who reach the age of majority at 18 without pursuing post-secondary education and without illness or disability, support obligations typically terminate upon the child's 18th birthday, provided the child has genuinely withdrawn from the parent's charge. The Maintenance Enforcement Program will cease enforcement when the child turns 18 if no qualifying conditions for extension exist.
For full-time students, MEP stops enforcing support automatically under three circumstances: the child turns 22, the child stops attending school full-time, or the child completes their first post-secondary degree, diploma, or certificate. MEP sends annual reminders to both parties to confirm the child's continuing enrollment status. If the recipient (the parent receiving support) notifies MEP that the child is no longer eligible, enforcement stops on the date the recipient specifies.
A court order may also contain specific termination dates or triggering events. For example, an order might state that support continues "until June 30, 2028, or until the child completes their undergraduate degree, whichever comes first." MEP follows such specific directions without requiring a further application to court.
| Scenario | Support Ends | Authority |
|---|---|---|
| Child turns 18, not in school, no disability | At age 18 | Divorce Act, s. 2(1)(a) |
| Child enrolled full-time in post-secondary | At completion of first degree/diploma or age 22 | Family Law Act + MEP policy |
| Child drops out of post-secondary | When full-time status ends | MEP enforcement policy |
| Child with disability preventing independence | No fixed end date — continues indefinitely | Divorce Act, s. 2(1)(b) |
| Child marries before 18 | At date of marriage | Common law withdrawal from charge |
| Court order specifies termination date | On date specified in order | Terms of the order |
| Child completes degree but pursues second degree | After first degree — requires new court order for extension | MEP re-registration required |
How to Apply to Terminate Child Support in Alberta
A paying parent who believes child support should end must apply to the Court of King's Bench for a variation order under Divorce Act, s. 17 (for married parents) or under the Family Law Act (for unmarried parents). The filing fee for a variation application at the Court of King's Bench is CAD $260, plus $10 for the Central Divorce Registry if the original order was a divorce order. Fee waivers are available for parents whose household income falls below government-set thresholds.
The application must demonstrate a "material change in circumstances" since the last order. A child reaching age 18, completing a degree, or becoming financially self-sufficient each qualifies as a material change. The applicant must file an Affidavit of Service, a Statement of Finances, and evidence supporting the claim that the child no longer qualifies for support. Common evidence includes the child's employment records, proof that the child has left school, or documentation showing the child is living independently.
If MEP is enforcing the order, the paying parent should also notify MEP directly by submitting a Child Status Report form. MEP cannot independently terminate enforcement without either a court order, notification from the recipient parent, or confirmation that the child has reached age 22 (for students) or 18 (for non-students). If MEP has already ceased enforcement and the recipient seeks to reinstate it, the recipient must re-register with MEP and pay a $205 registration fee, along with a new court order confirming the adult child's ongoing eligibility.
Child Support for Adult Children with Disabilities in Alberta
Alberta law provides no age limit for child support when an adult child is unable to withdraw from a parent's charge due to illness or disability. Under the Divorce Act, s. 2(1)(b), a child of any age who cannot obtain the necessaries of life because of a physical or mental health condition remains a "child of the marriage" entitled to ongoing parental support. The December 2018 amendments to Alberta's Family Law Act reinforced this principle by removing all age caps, ensuring that provincial law offers the same indefinite protection as federal law.
Courts assess the nature and severity of the disability, the child's capacity for any employment, the availability of government benefits such as the Assured Income for the Severely Handicapped (AISH) program, and the parents' respective financial circumstances. AISH provides a maximum monthly living allowance of $1,863 (as of 2025) for qualifying Albertans, but courts may find that this amount alone does not cover the child's full needs, particularly if the child requires specialized care, medication, or housing accommodations.
The paying parent retains the right to seek a variation if the child's condition improves or if government benefits increase sufficiently to cover the child's needs. However, Alberta courts have consistently held that a parent cannot unilaterally stop paying support for a disabled adult child without a court order. Doing so exposes the paying parent to arrears enforcement by MEP, including wage garnishment, driver's license suspension, federal license denial, and reporting to credit bureaus.
How the Alberta Maintenance Enforcement Program Handles Adult Child Support
The Alberta Maintenance Enforcement Program is the government agency responsible for collecting and distributing court-ordered child support payments. MEP enforces orders automatically once registered, and approximately 90% of all child support orders in Alberta are registered with the program. MEP has significant enforcement powers, including wage garnishment (up to 50% of wages in some cases), seizure of bank accounts, suspension of driver's licenses, denial of federal licenses (including passports), and reporting arrears to credit agencies.
For adult children, MEP follows specific enforcement protocols. When a child turns 18, MEP sends a notification to both parents advising that support may be ending. If the child is a full-time student, the recipient parent must provide proof of enrollment (typically a letter from the educational institution) to continue enforcement. MEP then enforces the order until the child turns 22, completes their first post-secondary credential, or ceases full-time enrollment.
MEP does not have the authority to modify the amount of child support or to make determinations about a child's eligibility for adult support. Those decisions rest with the Court of King's Bench. MEP's role is strictly enforcement of existing orders. If a paying parent believes support should end but the recipient disagrees, the paying parent must apply to court for a variation order — MEP cannot resolve the dispute.
Once MEP stops enforcing for an adult child, re-registration requires a new court order confirming the child's continued eligibility, a completed Creditor Registration Package, a Child Status Report, and a $205 registration fee. MEP will not resume enforcement based solely on the recipient's request without a supporting court order.
How Child Support Amount Is Calculated in Alberta
Alberta follows the Federal Child Support Guidelines and the Alberta Child Support Guidelines, Alta. Reg. 147/2005, which mirror the federal tables. The base amount of child support depends on the paying parent's gross annual income and the number of children. For example, a paying parent earning CAD $80,000 per year with one child would pay approximately $758 per month under the 2024 Federal Child Support Table amounts for Alberta. A parent earning $120,000 with two children would pay approximately $1,600 per month.
For adult children attending post-secondary education, courts may deviate from the standard table amount. Under section 3(2)(b) of the Federal Child Support Guidelines, when a child is over the age of majority, the court may order either the table amount or an amount it considers appropriate having regard to the child's condition, means, needs, and other circumstances, as well as the financial ability of each parent to contribute. Courts frequently adopt a contribution model where both parents share the child's reasonable educational and living expenses proportionally to their incomes.
Section 7 special or extraordinary expenses that commonly arise in post-secondary support cases include tuition and mandatory fees, textbooks and supplies, reasonable accommodation costs if the child must live away from home, and transportation costs for commuting students. The child is generally expected to contribute to their own expenses through employment earnings, scholarships, bursaries, and reasonable student loan borrowing. Courts typically expect a contribution of CAD $3,000 to $8,000 per year from the student, depending on local employment conditions and the academic demands of the program.
What Happens If You Stop Paying Child Support Without a Court Order in Alberta
Unilaterally stopping child support payments without a court order or MEP authorization is illegal in Alberta and triggers significant consequences. MEP enforcement actions include wage garnishment of up to 50% of the payor's income, seizure of bank accounts and investments, interception of federal payments including tax refunds, suspension of the payor's Alberta driver's license, denial or revocation of federal licenses and passports, registration of a lien against the payor's real property, reporting arrears to credit bureaus (which damages credit scores for up to 6 years), and in extreme cases, committal to jail for contempt of court for up to 90 days.
Child support arrears in Alberta do not expire. Unlike some debts that are subject to limitation periods, child support arrears remain enforceable indefinitely under the Maintenance Enforcement Act, RSA 2000, c M-1. Interest accrues on outstanding arrears, and MEP can pursue enforcement decades after the original support period has ended. As of 2025, MEP was enforcing approximately CAD $1.5 billion in outstanding child support arrears across Alberta.
Even if a paying parent believes the child is no longer eligible for support, the correct legal procedure is to apply to court for a variation order while continuing to make payments in full. Courts may retroactively adjust support if the variation application is successful, but the paying parent must continue paying the existing order amount until the court rules otherwise. The cost of a variation application (CAD $260 filing fee plus potential legal costs of $2,000 to $5,000) is far less than the consequences of unilateral non-payment.
When Does Child Support End Alberta: Key Differences Between Federal and Provincial Law
Alberta parents must navigate two overlapping legal frameworks for child support termination. The federal Divorce Act, R.S.C. 1985, c. 3 (2nd Supp.) governs child support when parents were legally married and obtained a divorce. The provincial Family Law Act, SA 2003, c F-4.5 applies to unmarried and common-law parents, and also governs support between married parents who separate without divorcing.
| Factor | Federal (Divorce Act) | Provincial (Family Law Act) |
|---|---|---|
| Applies to | Married parents who divorce | All parents (married, common-law, unmarried) |
| Definition of eligible child | "Child of the marriage" — s. 2(1) | "Adult child" unable to withdraw — s. 214 |
| Age cap | None | None (removed December 2018) |
| Qualifying causes for adult support | Illness, disability, "other cause" | Illness, disability, full-time student, "other cause" |
| Post-secondary specifically named | No (included under "other cause") | Yes (explicitly listed since 2018) |
| Burden of proof | On party claiming continued support | On party claiming continued support |
| Variation provision | s. 17 (material change in circumstances) | Part 6 of the Act |
| MEP enforcement | Yes (all registered orders) | Yes (all registered orders) |
The practical difference is minimal for most Alberta families. Both frameworks reach the same result: child support continues for adult children who cannot withdraw from a parent's charge due to illness, disability, or full-time post-secondary education. The December 2018 provincial amendments specifically harmonized the Family Law Act with the Divorce Act by adding "full-time student" as a named category and removing the former age-22 cap for provincial orders.
However, one notable procedural difference exists. Under the Divorce Act, the court must consider the child's "condition, means, needs, and other circumstances" along with the financial ability of each parent when setting support for an adult child. The Family Law Act uses similar but not identical language. In practice, Alberta courts apply the same analytical framework regardless of which statute governs the case.
Frequently Asked Questions About When Child Support Ends in Alberta
Does child support automatically end at 18 in Alberta?
No. Child support does not automatically end at age 18 in Alberta. Under the Divorce Act, s. 2(1) and Alberta Family Law Act, support continues for any child who remains unable to withdraw from a parent's charge due to illness, disability, full-time post-secondary enrollment, or other cause. The Maintenance Enforcement Program sends a status inquiry at age 18 but does not automatically cease enforcement if qualifying conditions exist.
What age does child support end in Alberta for a university student?
Child support for a full-time university student in Alberta typically continues until the child completes their first degree, diploma, or certificate, or turns 22 — whichever comes first. MEP enforces this as a default rule. However, courts can extend support beyond age 22 in exceptional circumstances, such as a student pursuing a combined degree program (e.g., a 5-year engineering program) or a student who experienced legitimate interruptions due to illness.
Can I stop paying child support if my child drops out of college?
A paying parent cannot unilaterally stop payments without a court order or MEP authorization. If the child drops out of post-secondary education, the paying parent should notify MEP and file a Child Status Report. MEP will investigate and may cease enforcement if the child is confirmed as no longer a full-time student. If the child is under 18, support continues regardless of school attendance. If the child is over 18 and not in school, the paying parent may apply to court for a variation order to terminate the obligation.
How much does it cost to apply to end child support in Alberta?
The filing fee for a variation application at the Court of King's Bench is CAD $260, plus $10 for the Central Divorce Registry if the original order was a divorce order. Fee waivers are available for low-income applicants. Legal representation for a variation application typically costs between CAD $2,000 and $5,000 if the matter is straightforward and uncontested, or CAD $8,000 to $15,000 if the other parent disputes the application. As of March 2026. Verify with your local Court of King's Bench registry.
Does child support end if my child gets a part-time job?
Part-time employment alone does not end child support in Alberta. Courts expect adult children to contribute to their own expenses through part-time and summer employment, typically CAD $3,000 to $8,000 per year. However, earning part-time income while attending school full-time does not make the child financially independent. Child support ends only when the child fully withdraws from the parent's charge, which requires genuine financial self-sufficiency — not merely supplemental income from a part-time position.
What if my child is 25 and still in school — do I still pay support?
Alberta removed all age caps for adult child support in its December 2018 Family Law Act amendments. Under both federal and provincial law, a child of any age who remains unable to withdraw from a parent's charge qualifies for continued support. However, courts scrutinize extended educational paths carefully. A 25-year-old pursuing a first professional degree (e.g., medicine or law) after completing an undergraduate degree may or may not qualify — the court examines whether the educational plan is reasonable and whether the child has made genuine efforts toward independence.
How does the Maintenance Enforcement Program know when to stop collecting?
MEP monitors child support orders through annual status reviews for adult children. MEP sends reminders to both parents each year requesting updated information about the child's enrollment status, employment, and living situation. MEP automatically stops enforcement when the child turns 22 (for students), when the recipient parent notifies MEP that the child is no longer eligible, or when a court order specifying a termination date is reached. MEP does not independently investigate — it relies on information from the parties and the terms of the court order.
Can child support be extended after MEP stops enforcing?
Yes. If MEP ceases enforcement but the child remains eligible for support, the recipient parent can apply to court for a new order confirming the child's continued entitlement. The recipient must then re-register with MEP by submitting a Creditor Registration Package, a Child Status Report, and paying a $205 registration fee. The new court order must specifically address the child's ongoing eligibility as an adult dependent. This process is common when a child with a disability continues to need support beyond the standard enforcement period.
Is there a difference between child support ending for married versus common-law parents in Alberta?
The practical outcome is identical for both. Married parents who divorce fall under the federal Divorce Act, while common-law and unmarried parents fall under the provincial Family Law Act. Both statutes provide that support continues for adult children who cannot withdraw from a parent's charge. The December 2018 amendments to the Family Law Act specifically harmonized the provincial framework with the Divorce Act, ensuring that common-law parents have the same obligations and rights as married parents regarding adult child support.
What happens to child support arrears after the child turns 18?
Child support arrears in Alberta do not expire regardless of the child's age. Under the Maintenance Enforcement Act, RSA 2000, c M-1, MEP can enforce outstanding arrears indefinitely. Even after the child reaches adulthood and support obligations end, any unpaid amounts from the period when support was owed remain fully enforceable. MEP can garnish wages, seize assets, suspend licenses, and take other enforcement actions to collect arrears. Interest continues to accrue on outstanding balances. As of 2025, MEP was enforcing approximately CAD $1.5 billion in total outstanding child support arrears across the province.
