Can I Claim Child Support for Past Years?
Did your ex's income increase without telling you? You might be owed 'Retroactive Support.' Learn the 4 strict tests from the Supreme Court (D.B.S.) that decide if you get paid.
Legal Review: This strategy guide was reviewed by Deepa Tailor, Senior Family Lawyer, to ensure compliance with the Supreme Court of Canada ruling in D.B.S. v. S.R.G. (2006).
Too Busy to Read? The 30-Second Answer
The Supreme Court's 4-Part Test
Before awarding retroactive pay, a Judge looks at:
Reason for Delay
Why didn't the Recipient ask sooner? Was it fear of violence? Lack of financial information? Or did they just sleep on their rights?
Conduct of the Payor
Did the Payor disclose their income increases voluntarily? Or did they hide raises and bonuses? (Hiding = Blameworthy).
Circumstances of the Child
Does the child still need the money? (Retroactive support is harder to get if the child is now an independent adult).
Hardship to the Payor
Will a massive lump-sum judgment bankrupt the Payor? (Note: Buying luxury cars instead of saving usually voids this defense).
The Most Important Email You Ever Sent
The 3-year clock starts ticking the moment you give "Effective Notice."
What counts?
It must be specific. A text saying "You need to pay more" is weak. A Lawyer's Letter saying "Please provide your 2024 NOA so we can recalculate support" is strong.
The Strategy
If you suspect income has gone up, ask for disclosure immediately in writing. This creates a "Footprint" that anchors your retroactive claim.
Pro Tip: Keep copies of all requests for financial disclosure. These documents become critical evidence if you need to prove you gave proper notice.
Retroactive vs. Arrears
The Myth
"It's All the Same"
Myth: "He didn't pay me last month, so I'm suing for retroactive support."
The Reality
"The Definition"
Reality: Arrears means he didn't pay the agreed amount. The FRO enforces this automatically. Retroactive Support means he paid the agreed amount, but the amount was wrong (too low) based on his true income. You need a Judge to fix this.
Will You Win?
The Winner (Recipient)
Scenario:
Mom asked for tax returns every year. Dad refused and said business was bad. Mom finds out Dad bought a cottage in cash 4 years ago.
Result:
Court awards 4+ years of retroactive support due to Dad's blameworthy conduct (hiding wealth).
The Loser (Recipient)
Scenario:
Dad's income rose slightly. Mom knew but didn't say anything because she didn't want to rock the boat. She asks for 5 years back-pay now that they are fighting about a new girlfriend.
Result:
Denied (or limited to 3 years). Mom accepted the status quo and Dad didn't hide anything.
