If you want clarity, the Ontario Court of Appeal gives it in Walsh and tells us that just because a child support payor has had a substantial increase in income a court shouldn’t make a variation order effective to a point before the variation proceedings began unless certain criteria are applied. Imputing a duty to disclose will only work in limited cases and absent that you’ll need to prove the child needed the extra support, the payor had the ability to pay it, and a bunch of factors are met.

Check out Child Support Guideline Material in the FLC’s Cases & Comments section for “When will a court make child support orders retroactive? The Ontario Court of Appeal gives the answer in Walsh v. Walsh” and also “Retroactive Child Support - Who's right is it anyway” to get the scoop.

Lesson: If it looks like the payor is living large make a demand for disclosure under s. 25(1) of the Child Support Guidelines. Or just go about making a disclosure anyway. And make sure that there’s some disclosure provision in any new separation agreement your drafting.

Adams v. Campbell, [2003] O.J. No. 3336, (Ont. C.J.). [Lawyers Weekly, Oct. 17/03]

Parties had an on-again, off-again relationship for several years. They never lived together but had 2 kids. M sought child support. F said only earned $19,000 and relied on credit cards and loans to exist. M disagreed and argued his lifestyle couldn't be maintained by such a low level of income. She alleged he was living off the avails of prostitution. Interim order imputed $61,000 income to F. At trial neither F nor his witnesses were found credible. From the evidence (F drove various vehicles, lived in a fully furnished home in a good neighbourhood, had time and money for flight instructions, and had access to personal credit of $130,000) the court didn't believe he was only earning $19,000. But after all of that court ended up only imputing $38,016 income to F as the amount to sustain his lifestyle. He had to pay $544 instead of $236 for $16,000.

Lesson: M's persistence paid off - but was cost of trial worth it?

Query: We wonder if he put in an offer to avoid the trial.
