Virtual appointmentsAbout James S. Marks
James S. Marks is a solo family law practice in Toronto, run out of an office in the Manulife Centre at Bay and Bloor. The firm's site describes Marks as holding a master's degree in family law and practising family law in Toronto for more than 20 years, with work that covers separation and domestic contracts, uncontested and complex divorce, child custody and access, spousal and child support, property division, and prenuptial agreements. Complex files often involve high income earners, real estate portfolios, or business valuations, and the firm says it has represented clients throughout Ontario and appeared at every level of court in the province, including the Ontario Court of Appeal, as well as testifying as an expert witness in U.S. Federal Court.
A distinct part of the practice is international family law, particularly Hague Convention applications for the return of children who have been wrongfully removed from or retained outside Canada. The firm's site lists involvement in cases seeking a child's return to Australia, Botswana, Italy, Sweden, the United Kingdom, the United Arab Emirates, and the United States, and cases seeking a child's return to Canada from Bulgaria and India. The firm's own published list of court decisions runs from a 1988 matter through cases decided as recently as 2020, spanning Ontario Superior Court proceedings on custody, support, and related motions.

Who handles what
The neighbourhood
The office is in the Manulife Centre complex, the mixed use tower and retail development that anchors the corner of Bay and Bloor in downtown Toronto, at the southern edge of Yorkville. Built in the early 1970s, the complex connects underground to the Bloor-Yonge subway interchange, one of the busiest in the city, which keeps the office within easy transit reach of clients coming from across Toronto and, as the firm's site notes, from elsewhere in Ontario for the family law and Hague Convention matters it takes on.
