Beyond the basic calculation. How to resolve disputes involving hidden income, Section 7 expenses, and refusal to pay.
Legal Review: This troubleshooting guide was reviewed by Deepa Tailor, Senior Family Lawyer, to ensure compliance with the Federal Child Support Guidelines and recent case law on income determination (2026).
While the 'Table Amount' seems simple, real life is messy. The most common legal battles in Ontario involve: 1) Determining the true income of self-employed payors, 2) Agreeing on what counts as a 'Special Expense' (Section 7), 3) Enforcing payment when arrears pile up, and 4) Deciding when support ends for adult children. Each issue requires a specific legal remedy, from 'Imputing Income' to filing 'Motions to Change.'
The Issue:
Payor works for cash or writes off personal expenses.
The Fix:
We hire forensic experts to analyze bank statements and ask the court to 'Impute Income' based on lifestyle.
The Issue:
Disagreement over private school tuition or expensive sports.
The Fix:
The test is 'Necessity and Reasonableness.' We review the expense against the combined family income.
The Issue:
Payor quits a high-paying job to avoid paying support.
The Fix:
Courts do not tolerate this. We ask the judge to set support based on *what they could earn*, not what they currently earn.
The Issue:
Child is 22, living at home, not in school, but payor is still paying.
The Fix:
We file a Motion to Change to terminate support based on the child's withdrawal from parental control.
The other parent ignores your requests for tax returns (NOAs). They claim their finances are 'private' now that you are separated.
Child support requires transparency. Privacy does not exist here. If they refuse to provide disclosure within 30 days, we obtain a Court Order forcing them to produce it, often with 'Costs' (fines) payable to you.
We send a formal letter outlining the issue (e.g., 'You owe $500 for braces') and attaching the receipt/proof.
If they ignore the letter, we suggest a 4-way meeting to resolve the dispute without a judge.
If they still refuse, we file a Motion. We present the evidence to a judge who will make a binding Order.
We register the new Order with the FRO to ensure compliance via wage garnishment.
