About Viater Perelman Family Law Group

Viater Perelman Family Law Group is a family law firm based in Toronto, with a main office on Yonge Street and a second office in Vaughan. Its two lawyers, Philip Viater and Lyna Perelman, whose names the firm carries, focus on separation and divorce and the range of issues that come with them, from child custody, access and mobility disputes to child and spousal support and the division of property.

Viater earned a Juris Doctor at Osgoode Hall Law School, and Perelman earned a Juris Doctor at Queen's University. The firm handles both court litigation and alternative dispute resolution, including mediation and four-way settlement meetings, and it says it takes on matters for clients across the Greater Toronto Area, including Barrie, Burlington, Milton, Newmarket, Oakville, Oshawa and Toronto, as well as international clients it meets with remotely.

The neighbourhood

The firm works out of two locations rather than one downtown storefront, a main office on Yonge Street in Toronto and a second office in Vaughan. That two-office footprint matches how broadly it says it works: it lists clients from Barrie, Burlington, Milton, Newmarket, Oakville and Oshawa alongside Toronto itself, plus international clients it meets with remotely. For a family law practice, having a base in both the city and the surrounding region makes it possible to meet people closer to home during a separation, rather than asking everyone to travel to a single office.
