After her call to the Ontario Bar in 1985, Darlene Madott began her career as a litigator, and participated in precedent-setting cases, which included:

• A Trinidad husband obtains a stay of Ontario proceedings based on Trinidad being the more substantial jurisdiction (Nicholas);
• A woman obtains the right to sue grandparents for support, based on a contractual concept of the family (Cheng);
• An international child abduction case raises constitutional and conflict-of-laws issues where immigration legislation conflicts with the Children’s Law Reform Act and the return of abducted children to the home jurisdiction (Maharaj);
• A mobility case, where an access father successfully resists the move of his children with their mother to North Bay, (Tumino);
• In an Application for variation of child support and financial disclosure, where the parties had a separation agreement that provided for non-variable child support, special expenses, and waiver of future financial disclosure, the father was ordered to provide financial disclosure as mandated by the Child Support Guidelines and the information was ordered sealed for 12 months. (Quinn v. Keiper).
