Child Support in a BC Divorce

Judges Will Not Sign Your Divorce If the Numbers Are Wrong

One of the most common reasons BC desk order divorce applications are rejected has nothing to do with missing forms or expired affidavits. It is the child support math. Under the Divorce Act, a judge has an explicit statutory duty to satisfy themselves that reasonable child support arrangements are in place before granting a divorce. If the numbers do not align with the Federal Child Support Guidelines, the judge sends the package back.

This means you cannot simply agree on a "fair" number with your spouse. The guidelines set the baseline, and the court enforces it.

How the Federal Child Support Guidelines Work

The guidelines use a table-based system. You look up the paying parent's gross annual income and the number of children, and the table produces a monthly dollar amount. That amount is the presumptive minimum — it is what the judge expects to see in your separation agreement and on Form F37 (Child Support Affidavit).

The tables are published by the federal Department of Justice and are province-specific (BC has its own table because provincial tax rates affect the calculation). You can run the numbers using the federal Child Support Table Lookup tool available on the Department of Justice website.

For example, a parent earning CA$60,000 per year with two children in BC would see a guideline amount of roughly CA$939 per month. If your separation agreement says CA$700, the judge will reject the desk order unless you provide exhaustive sworn proof explaining and supporting the deviation.

When Adjustments Are Allowed

The guidelines are not entirely rigid. Three situations can affect the amount beyond the basic table amount:

Shared custody (40% or more parenting time). When each parent has the children at least 40% of the time, the court considers both parents' incomes and the increased costs of maintaining two full-time households. The table amount can be adjusted downward — but this is not automatic. You must show the actual split and the financial impact.

Special or extraordinary expenses (Section 7). Certain costs are shared on top of the base guideline amount, proportional to each parent's income. These include childcare required for the custodial parent to work, health insurance premiums, health-related expenses that exceed insurance reimbursement by at least CA$100 annually, educational expenses, and extracurricular activity costs. Both parents contribute to these in proportion to their respective incomes.

Undue hardship. If paying the guideline amount would leave the paying parent unable to meet their basic needs — for example, because they are supporting children from a second relationship or carrying unusually high debts from the marriage — the court can reduce the amount. This requires detailed financial proof and a comparison of each household's standard of living.

What Goes on Form F37

The Child Support Affidavit (Form F37) is the document where you present the child support arrangement to the judge. It must include:

• Each parent's gross annual income, supported by tax returns or pay stubs
• The number and ages of dependent children
• Which parent has primary residence (or the exact percentage split for shared custody)
• The specific child support amount being paid and how it was calculated
• A copy of the separation agreement attached as a lettered exhibit

If the amount matches the guideline tables, the affidavit is straightforward. If it deviates, you need to attach exhaustive sworn proof explaining why the deviation is reasonable and showing that your child will not experience financial detriment, with supporting financial evidence.

The 30-Day Affidavit Clock

Like every affidavit in a BC desk order package, Form F37 must be filed at the registry within 30 days of being sworn. If you swear it and then wait too long to file the rest of the package, the affidavit expires and must be re-sworn — costing another CA$40 in swearing fees and potentially delaying the entire proceeding.

Getting the Child Support Section Right

The British Columbia Divorce Filing Process Guide includes a child support calculation worksheet that walks you through the guideline tables, Section 7 expense allocation, and shared-custody adjustments, then maps the results directly to what goes on Form F37. This is the section that most often derails self-filed divorces, and getting it right the first time avoids the most expensive kind of rejection.
