A child support lawyer in Calgary at Centobin Law Office helps parents navigate these calculations — from determining base table amounts and Section 7 extraordinary expenses to handling shared parenting adjustments and income disputes.

Child support in Alberta is a legal obligation requiring both parents to contribute financially to their child’s upbringing after separation or divorce. Under Alberta’s Family Law Act and the federal Divorce Act (RSC 1985, c 3), child support is considered the right of the child — not the parent — and cannot be waived by mutual agreement between parents without court approval.
Federal Child Support Guidelines (SOR/97-175) apply to all divorce cases in Alberta. Because Alberta is not a “designated province,” federal guidelines apply automatically when married parents divorce under the Divorce Act. Alberta Child Support Guidelines (Alta Reg 147/2005) apply under the Family Law Act when parents were never married or when married parents have separated, but neither has filed for divorce. Both sets of guidelines use identical Federal Child Support Tables for Alberta, meaning the calculation produces the same base amount regardless of whether parents are married or unmarried.
Section 7 expenses may include:
Proportional sharing example: if Parent A earns $80,000 and Parent B earns $40,000, their combined income is $120,000. Parent A is responsible for 67% of Section 7 expenses, and Parent B for 33%. If a child’s annual hockey expenses total $6,000, Parent A pays $4,020 and Parent B pays $1,980. Centobin Law Office, a family law firm in Calgary, helps parents identify which expenses qualify under Section 7, negotiate proportional sharing arrangements, and present evidence to the Calgary Court of King’s Bench when parents cannot agree on whether an expense is necessary or reasonable.
Child support for adult children in Alberta continues beyond the age of majority (18) when the child is unable to withdraw from their parents’ charge or obtain the necessities of life. Alberta’s Family Law Act was amended in December 2018 to clarify that adult children are eligible for ongoing support if they meet both conditions: they remain under a parent’s charge, and they cannot independently provide for their own basic needs. The most common circumstances where child support extends past 18 include:
Important distinction: under the Divorce Act, the test is slightly different — support continues for a “child of the marriage” who is unable to withdraw from parental charge by reason of illness, disability, or “other cause” (which the courts have interpreted to include post-secondary education). The practical effect in Alberta is similar under both statutes. Centobin Law Office, a family law firm in Calgary, represents both parents seeking to establish adult child support and parents seeking to terminate support when an adult child is no longer eligible.
Imputed income for child support in Alberta allows the court to assign a higher income to a parent who is deliberately underemployed, unemployed without a valid reason, or diverting income to avoid child support obligations. Under Section 19 of the Federal Child Support Guidelines, the court can determine a parent’s true earning capacity and calculate child support based on what they should be earning rather than what they report. Alberta courts may impute income in the following circumstances:
The court considers what the parent could reasonably earn given their education, work experience, skills, and the local job market. A family law lawyer in Calgary at Centobin Law Office prepares imputed income applications with detailed evidentiary support — including forensic accounting referrals when necessary.
Enforcing a child support order in Calgary is handled primarily through Alberta’s Maintenance Enforcement Program (MEP), a government agency with broad powers to collect unpaid child support. When a paying parent falls behind on court-ordered child support, MEP can take enforcement action without the recipient parent needing to return to court. All child support orders in Alberta are automatically filed with MEP unless both parties opt out.

All child support orders in Alberta are automatically filed with the Maintenance Enforcement Program (MEP) unless both parties opt out, so payments are tracked from the outset even when a paying parent complies voluntarily.
Enforcing a child support order in Calgary is handled primarily through Alberta’s Maintenance Enforcement Program (MEP), a government agency with broad powers to collect unpaid child support. When a paying parent falls behind on court-ordered child support, MEP can take enforcement action without the recipient parent needing to return to court. MEP has significant enforcement tools available, including:
In some cases, standard MEP enforcement is insufficient — particularly when the paying parent is self-employed, has moved assets out of reach, earns income through a corporation, or has left Alberta. In these situations, a Calgary child support lawyer at Centobin Law Office can pursue additional enforcement remedies through the Calgary Court of King’s Bench, including applications to impute income where a parent is deliberately underemployed or hiding earnings, tracing orders to locate hidden assets, and interjurisdictional enforcement when the paying parent has moved to another province or country.
Registration with MEP happens automatically for Alberta child support orders, so families are rarely starting an enforcement process from zero.
(403) 249-1733Child support in Alberta is calculated using the Federal Child Support Tables, which set a base monthly payment determined by the paying parent’s gross annual income, the number of children requiring support, and the province of residence. The tables were updated on October 1, 2025, incorporating 2023 federal and provincial tax rules — replacing the previous version that used 2017 tax rules.
The calculation involves three core factors:

| Gross Annual Income | Approx. Monthly Base Support (1 Child) |
|---|---|
| $30,000 | ~$264 |
| $40,000 | ~$362 |
| $50,000 | ~$466 |
| $60,000 | ~$575 |
| $80,000 | ~$735 |
| $100,000 | ~$896 |
| $150,000 | ~$1,264 |
Amounts reflect the October 2025 Federal Child Support Tables for Alberta. Actual amounts vary based on the number of children and specific parenting arrangements. A Calgary child support lawyer at Centobin Law Office reviews each parent’s complete financial picture — including bonuses, commissions, investment income, and any self-employment adjustments — to ensure the calculation accurately reflects true income.
Hiring a child support lawyer in Calgary is essential when support calculations involve complex income, disputed parenting arrangements, Section 7 expense disagreements, or enforcement challenges. While the Federal Child Support Guidelines provide a framework, the application of those guidelines to real family situations frequently requires legal analysis, financial evidence, and courtroom advocacy.
When a parent earns income through a corporation, partnership, or sole proprietorship, determining guideline income requires analysis beyond the tax return. Business expenses may need to be added back, corporate retained earnings may be attributed as personal income, and multiple years of financial statements may need review. This is one of the most litigated areas of child support law in Alberta.
Parents frequently disagree on whether an expense qualifies as “extraordinary” under Section 7 — particularly for extracurricular activities. A lawyer presents the legal test (necessity for the child’s best interests and reasonableness relative to means) with supporting evidence.
When MEP enforcement tools are insufficient — particularly with self-employed payors or parents who have moved assets — a lawyer can pursue additional court remedies, including imputed income applications and tracing orders.
When one parent lives outside Alberta or outside Canada, child support involves interjurisdictional legislation and potentially international treaties. These cases require legal expertise to navigate procedural requirements.
At Centobin Law Office, our family law team handles child support matters at every complexity level, no matter which of these situations applies.
Discuss Your Child Support MatterModifying a child support order in Alberta requires demonstrating a “material change in circumstances” since the original order was made.
Modifying a child support order in Alberta requires demonstrating a “material change in circumstances” since the original order was made. Under both the Divorce Act and Alberta’s Family Law Act, either parent can apply to the court for a variation when financial or parenting circumstances have changed significantly enough to produce a different support amount under the guidelines. Common grounds for modification include:
The October 2025 update to the Federal Child Support Tables does not automatically change existing court orders. If the new tables produce a different amount for your income level, you must apply to the court for a variation or use Alberta’s Child Support Recalculation Program.
Alberta’s Child Support Recalculation Program (CSRP) automatically recalculates child support amounts annually based on updated income information — without requiring a return to court. The CSRP is available when the existing child support order or agreement was made under the Alberta Family Law Act or the Divorce Act, both parents live in Alberta, and the order is based on the Federal Child Support Guidelines table amounts.
The CSRP sends annual requests for updated income tax information to both parents. If income has changed, the program issues a recalculated amount that takes effect automatically unless a parent objects within 30 days.
Centobin Law Office, a family law firm in Calgary, assists parents with recalculation applications and, where a court variation is the right path, prepares and files the application at the Court of King’s Bench.
Child support obligations in Canada interact with immigration law in several critical ways — from sponsorship undertakings that create enforceable financial commitments to the impact of unpaid child support on immigration applications. Parents navigating both family law and immigration proceedings need legal guidance that accounts for both systems simultaneously.
Sponsorship Undertakings and Child Support: when a Canadian citizen or permanent resident sponsors a spouse or dependent child, they sign a legally binding sponsorship undertaking — a commitment to financially support the sponsored person for a fixed period (3 years for a spouse, up to 22 years for a dependent child, depending on age at sponsorship). If the relationship breaks down during the undertaking period, the sponsor remains financially responsible regardless of separation.
Unpaid Child Support and Immigration Applications: applicants with outstanding child support arrears may face complications in immigration proceedings. While unpaid child support alone does not create inadmissibility, it can affect an applicant’s ability to demonstrate financial self-sufficiency — a requirement for many immigration programs, including Express Entry and Provincial Nominee Programs.
Child Support for Children Abroad: Alberta courts can order child support for children residing outside Canada. The Federal Child Support Guidelines apply regardless of where the child lives, and interjurisdictional enforcement mechanisms exist through treaties and provincial legislation.
Centobin Law Office is uniquely positioned to advise clients whose family law and immigration matters intersect — our immigration lawyer in Calgary and family law teams collaborate to ensure that child support orders, sponsorship undertakings, and immigration applications are coordinated from the outset.

Book a confidential consultationAt Centobin Law Office, our family law team handles child support matters at every complexity level — from straightforward guideline calculations to contested hearings at the Calgary Court of King’s Bench involving forensic accounting evidence and corporate income attribution.
Book a confidential consultationMost child support disputes in Calgary do not involve disagreements about whether support should be paid — they involve disagreements about income. In our experience representing families at the Calgary Court of King’s Bench (Family Division), the single most effective step a parent can take is ensuring complete and timely financial disclosure from the outset. Alberta courts take a dim view of parents who delay or obstruct financial disclosure. In contested cases, the court has broad discretion to draw adverse inferences — meaning if a parent refuses to produce financial records, the court can assume the missing information would have supported a higher income finding.
Book a confidential consultationFor self-employed parents, we routinely work with forensic accountants to reconstruct true income from corporate financial statements, personal expenditure analysis, and asset acquisition patterns.
Book a confidential consultationThe amount depends on the paying parent’s gross annual income, the number of children, and the parenting arrangement. Under the October 2025 Federal Child Support Tables for Alberta, a parent earning $60,000 pays approximately $575 per month for one child. Shared parenting arrangements (40% or more time with each parent) use a different calculation that compares both parents’ table amounts.
Alberta’s Maintenance Enforcement Program (MEP) can garnish wages, seize tax refunds, suspend the paying parent’s driver’s licence, deny passport renewal, and register liens on their property. If MEP enforcement is insufficient, a family lawyer can pursue additional court remedies, including imputed income applications and asset tracing orders.
Section 7 expenses are additional costs beyond the base child support amount — including child care, uninsured health expenses over $100 annually, extraordinary extracurricular activities, and post-secondary education costs. Both parents share these expenses proportionally based on their respective incomes.
Self-employed parents’ child support is calculated based on their true income, which may differ from what they report on tax returns. The court can add back unreasonable business expenses, attribute corporate retained earnings as personal income, and impute a higher income if the parent is deliberately underreporting. Forensic accounting analysis is often necessary in these cases.
Yes. Either parent can apply to vary a child support order when there has been a material change in circumstances — such as a significant income change, a change in parenting time, or the child reaching the age of majority. Alberta’s Child Support Recalculation Program can also adjust amounts annually without a court application.
Not necessarily. Under Alberta’s Family Law Act (amended in December 2018), child support continues when an adult child is unable to withdraw from parental charge — typically because they are a full-time post-secondary student, have a disability, or cannot independently obtain the necessities of life.
While unpaid child support does not create direct inadmissibility under Canada’s Immigration and Refugee Protection Act, outstanding arrears can affect an applicant’s ability to demonstrate financial self-sufficiency. Sponsorship undertakings also create binding financial obligations that survive separation or divorce.
