Getting a Self-Employed Ex's Real Income Onto the Table

The situation

Winnie worked as a police sergeant in Ottawa's east end and shared two children with Alejandro, her former partner, who ran a small home renovation business. Their separation agreement, signed four years earlier, set child support based on Alejandro's reported self-employment income of roughly $38,000 a year. On paper, that made him a modest earner. In practice, Winnie watched him renovate a second property, drive a newer truck, and take the kids on trips that did not look like they came from a $38,000 income.

Winnie had since built a life with Mateo, a sales director, and between the two of them the household income sat comfortably in the $150,000 to $300,000 range, with some home equity and investments built up over the relationship. She was not desperate for the money. She wanted the support figure to reflect reality, because her children were splitting time in two households and one of those households was, by every outward sign, doing considerably better than its tax returns suggested.

The legal problem

Child support in Ontario is calculated using the Child Support Guidelines, which set a payor's support obligation based on their income. For an employee, income is usually a simple number pulled from a pay stub or tax slip. For someone self-employed, it is rarely that simple. Self-employed payors report income after deducting business expenses, and some of those deductions are legitimate business costs while others quietly convert personal spending into a business write-off. A truck used partly for job sites and partly for the family, materials bought at a discount and resold privately, cash payments from clients who prefer not to leave a paper trail — all of it can shrink a reported income figure well below what is actually available to live on.

Courts are alive to this problem. Where a payor's stated income does not match their actual spending and standard of living, a court can impute income — meaning it can assign the payor an income figure higher than what their tax return shows, based on what the evidence indicates they actually earn or could reasonably earn. But imputation is not granted on suspicion alone. It takes a documented pattern: bank deposits well beyond declared revenue, personal expenses run through the business, assets acquired that a $38,000 income could not support, or a lifestyle that simply does not add up. Winnie's instinct that something was off was not, by itself, enough to move a judge.

What we did

1. Reviewed the existing agreement and support history. We confirmed the original figure was based on a single year's tax return with no ongoing disclosure obligation attached, which meant Alejandro had never been required to update Winnie on his income since the separation agreement was signed.
2. Sent a formal request for financial disclosure. Under the disclosure obligations that apply once a variation is sought, we requested three years of tax returns, notices of assessment, business bank statements, and records for any corporation or business account tied to his renovation work. This is a standard first step before any court application, and it often resolves matters on its own if the other side knows the numbers will not survive scrutiny.
3. Built a lifestyle and deposit analysis. When the disclosure came back incomplete, we worked with Winnie to compile independent evidence: property records showing the second property Alejandro had renovated and sold, social media and message threads referencing vacations and purchases, and bank deposit patterns visible from shared household records during the years they had lived together. None of this proved an exact income figure, but together it painted a picture inconsistent with $38,000 a year.
4. Brought an application to vary child support. With the gap between reported income and apparent spending clearly laid out, we applied to family court for a variation, asking the court to impute Alejandro's income based on the available evidence rather than accept his tax filings at face value.
5. Negotiated from a position of documented strength. Facing a court application built on concrete deposit and lifestyle evidence rather than vague suspicion, Alejandro's counsel engaged in settlement discussions. Litigation over imputed income can turn into a costly, document-heavy fight, and both sides had reason to prefer a negotiated resolution once the evidence was on the table.

The outcome

The matter settled before a full hearing was needed. Alejandro's counsel agreed to an imputed income figure of roughly $95,000 a year, reflecting the business bank deposits and asset pattern the disclosure and independent evidence had surfaced. Going forward, child support was recalculated under the guidelines using that figure, roughly doubling the monthly amount Winnie had been receiving. The settlement also included a retroactive adjustment covering the eighteen months since Winnie had first raised the discrepancy, totalling approximately $14,000, paid over a structured schedule rather than as a lump sum Alejandro could not otherwise meet.

Just as important for Winnie was the ongoing disclosure clause built into the new agreement: Alejandro is now required to provide annual tax returns and notices of assessment automatically, without Winnie having to chase them down or start another court process each time she suspects the numbers have shifted again. For a self-employed payor whose income can genuinely fluctuate year to year, that kind of standing disclosure obligation is often more valuable long-term than the immediate dollar figure, because it closes the door on the same dispute recurring every few years.
