The parties separated after a ten-year traditional marriage.
The separation agreement provided for time-limited spousal support and child support.
The father's income subsequently increased substantially, and the parties' son moved in with the father while the daughter remained with the mother.
The father drafted an amending agreement reducing child support, which the mother signed without financial disclosure or independent legal advice.
The mother later applied to vary spousal and child support, seeking retroactive increases.
The trial judge increased support but declined to make it retroactive to the date the father's income increased.
The Court of Appeal allowed the appeal in part, increasing the quantum of spousal support to reflect the mother's economic disadvantage and making the child support increase retroactive due to the father's financial non-disclosure and blameworthy conduct.
