Child support can appear straightforward when a parent’s income comes from a regular salary and the parenting arrangement is simple. In practice, disputes often arise over income, shared parenting, special expenses, changes in employment, business income or support that was not adjusted when circumstances changed.
At Verhaeghe Law Office, our Edmonton child support lawyers assist parents with understanding, calculating, negotiating and changing child-support obligations.

Which Child Support Rules Apply to Your Family?
The child support obligations for Alberta families may fall under either federal or provincial legislation, depending on their circumstances.
Where married parents are divorcing, the federal Divorce Act and Federal Child Support Guidelines generally apply. It is important to note that updates to the federal child support guidelines went into effect on October 1st, 2025.
In non-divorce situations, Alberta’s Family Law Act and Alberta Child Support Guidelines may apply.
The Government of Alberta explains that the provincial guidelines are modelled on the federal guidelines so that support calculations are approached consistently regardless of the parents’ relationship status.
How Is Child Support Calculated in Alberta?
A basic calculation generally starts with the applicable support table.
The amount that’s supposed to be paid usually depends on factors such as the payor’s guideline income, province of residence, and number of children.
That starting point does not resolve every case.
Different rules may become relevant where parenting time is shared, a child is over the age of majority, income is difficult to determine, or special expenses are claimed.
Determining Income Under The Child Support Guidelines
For an employee receiving a stable salary, guideline income may be relatively easy to identify. Other situations can require closer analysis.
A parent may be self-employed, operate through a corporation, receive bonuses or commissions, earn income from investments, experience substantial yearly fluctuations, or claim business expenses that receive different treatment for income-tax and child-support purposes.
The Federal Child Support Guidelines contain provisions addressing circumstances where ordinary tax income does not provide the full picture.
Where appropriate, a court may also impute income rather than relying exclusively on the figure reported by the parent.
For this reason, an accurate child-support assessment can require more than looking at a single line on a Notice of Assessment. Our Edmonton child support lawyers can help assess each parent’s financial situation to determine an accurate child support amount.
What Are Section 7 Expenses?
Certain expenses may be payable in addition to the regular table amount for child support.
These are often called section 7 expenses because they are addressed by section 7 of the Federal Child Support Guidelines. They may also be referred to as special or extraordinary expenses.
Depending on the circumstances, they may include additional childcare expenses incurred because of employment or education, certain health-related expenses, some educational expenses, and qualifying extracurricular costs.
Not every cost incurred for a child automatically becomes a section 7 expense. The nature of the expense, the child’s needs, the family’s circumstances, and the reasonableness of the cost may all be taken into consideration.
The parents’ respective contributions to section 7 expenses are also not necessarily a simple 50/50 split.
Child Support In Shared Parenting Arrangements
Shared or equal parenting does not automatically eliminate the need for child support to be paid.
Under the federal Guidelines, a specific analysis applies where each parent exercises at least 40 percent of parenting time over the course of a year. This is sometimes referred to as the 40 percent rule during child support disputes.
The court considers the table amounts that would otherwise apply to each parent as well as increased costs associated with shared parenting and the conditions, means, needs, and circumstances of the parents and children.
As a result, two families with similar schedules can still have different support outcomes because their incomes and financial circumstances differ.
A parenting plan and a child-support calculation conducted by an experienced child support lawyer can help address these questions.
Child Support For Adult Children
Child support does not always end automatically when a child turns 18.
Under Alberta law, support may continue for an adult child who remains under a parent’s charge and cannot withdraw from that charge or obtain the necessaries of life because of illness, disability, full-time studies, or another qualifying cause.
For divorcing parents, the Divorce Act contains its own definition addressing children of the marriage who have reached the age of majority but remain unable to become independent for eligible reasons.
If your child is attending college, university, or another post-secondary institution, additional support questions can be created that require more analysis than simply applying an age cutoff.
What If A Parent Refuses To Provide Income Information to Avoid Paying Child Support?
Financial disclosure is fundamental to determining child support.
Alberta’s child-support application process may require each parent to provide tax returns, Notices of Assessment, current proof of income, and any information relating to special expenses.
If the other parent refuses to disclose relevant financial information voluntarily, formal requests and court procedures may be invoked.
Where the parent owns a business or controls a corporation, the disclosure required may extend beyond personal tax returns.
Failure to disclose does not necessarily allow that parent to avoid an accurate support determination. If a parent is refusing to report all sources of income accurately, our child support lawyers in Edmonton can help.
Can Child Support Payments Be Changed in Alberta?
Yes. Generally, child support can change over time.
A parent’s income may rise or fall. Parenting arrangements may change. A child may begin post-secondary education or cease to qualify for support once they reach a certain age.
However, a change in circumstances does not necessarily mean a payor can simply begin paying a different amount.
Where support is contained in a court order or agreement, the appropriate process for updating it should be followed.
Alberta also operates a Child Support Recalculation Program for eligible orders.
Whether recalculation, negotiation, or a formal variation application is the appropriate route depends on the existing arrangement.
Understanding Child Support Arrears in Alberta
Arrears are amounts of child support that have been unpaid or are overdue.
Problems can develop where a payor loses employment or experiences reduced income but continues to be bound by an existing order.
A payor should not assume that an income reduction automatically changes the legal obligation retroactively. Without having a change formalized legally, support obligations generally remain the same.
Likewise, a recipient dealing with substantial arrears may need to consider enforcement and whether the existing support accurately reflects the payor’s historical income.
Alberta’s Maintenance Enforcement Program can enforce eligible child- and spousal-support obligations.
Determining Retroactive Child Support
A retroactive child-support claim can arise when support was not paid or was paid at an amount that did not reflect the proper income. If it is found at a later date that child support payments should have been greater, the payor may owe the difference.
These cases can be complicated because they require reviewing several years of income, disclosure history, changes in parenting arrangements, and communications between the parents.
The fact that years have passed does not necessarily provide a simple answer in either direction.
Legal advice can be particularly useful when substantial historical support is at issue.
How Our Edmonton Child Support Lawyers Can Help
Our child support lawyers in Edmonton can help families across Alberta determine which guidelines apply and calculate an appropriate support amount based on the available financial information.
Where income is straightforward, that may involve reviewing tax records and applying the current tables and guidelines.
If income is more complicated, we can examine business records, corporate financial statements, employment benefits, bonuses, or other sources that may affect guideline income.
We also assist with section 7 expenses and help clients determine whether particular costs may qualify and how contributions should be addressed.
If a parent has not completed financial disclosure, we can request additional information and take appropriate procedural steps if disclosure is not provided.
We can also prepare or review support agreements, seek or respond to support orders, address arrears, and bring or respond to applications to vary support when circumstances have materially changed.
Where child support arises alongside divorce or spousal support, our broader Edmonton family law lawyers can address the issues together.
Frequently Asked Questions About Child Support In Edmonton
Who Pays Child Support?
That depends on the parenting arrangement, the income of each parent, and applicable support rules.
In many primary-residence arrangements, the parent with less parenting time pays the table amount to the other parent. Shared parenting situations require a different analysis.
Is Child Support Based On Gross Or Net Income?
The Guidelines generally use income determined under their own rules, which often begins with total income reported for tax purposes and may then require adjustments.
It is therefore not simply a person’s monthly take-home pay.
What If My Former Partner Is Self-Employed?
Self-employed income can require closer review because business expenses accepted for tax purposes do not always determine income for child-support purposes.
Corporate financial statements, shareholder information, and other records may need to be reviewed by a professional in these cases.
Can Someone Quit Their Job To Avoid Paying Child Support?
A voluntary reduction in income does not automatically reduce child support obligations.
The Guidelines permit income to be imputed in certain circumstances, including some situations involving intentional underemployment or unemployment.
The facts and reasons for the income change matter.
Does 50/50 Parenting Mean Nobody Pays Child Support?
No. Shared parenting changes the analysis, but it does not create an automatic zero-support rule.
Does Child Support End At Age 18?
Not necessarily. Support can continue where an adult child remains legally dependent because of education, illness, disability, or another qualifying circumstance outlined in the guidelines.
What if I Pay Child Support and I Lose My Job?
A genuine income change may justify reviewing support, but an existing order should not simply be ignored. If you have lost your job, there is a way to vary your child support order to reflect your current financial situation.
Acting promptly can be important because arrears may continue accumulating while the existing obligation remains in effect.
Can Child Support Be Changed Without Going To Court?
Sometimes. Parents may be able to reach a new agreement themselves, obtain a consent order, or use Alberta’s recalculation process where the case qualifies.
The appropriate option depends on the existing order or agreement.
