About Paul D. Slan

Family law has been Paul D. Slan's field since 1977, and today Paul is a senior lawyer at Gelman & Associates. Paul works on disputes both in court, including appeals at the Court of Appeal for Ontario, and away from it, as a certified mediator and arbitrator who's also trained in collaborative family law.

Paul once chaired the Ontario Bar Association's Family Law Section, taught family law in the Bar Admission Course and sat as a Dispute Resolution Officer for the Superior Court of Justice in Toronto. Paul was also a panel lawyer for the Office of the Children's Lawyer, acting for children. Sierra Hall articled under Paul and was called to the Bar in 2024.

Away from the office, Paul runs marathons and has raced in Toronto, Ottawa and Las Vegas, with an 18 week training build and the Running Room's group for motivation. Qualifying for Boston sits at the top of Paul's bucket list. Paul cycles as well, genuinely likes time at the gym, and is a father of three and a grandfather of three.

Family appeals

After a trial judge dismissed a husband's unjust enrichment and resulting trust claims and awarded costs to the wife, Paul and Annie Yektaeian represented the wife once the husband moved forward with an appeal.
