About Birch Law

Birch Law is a family law practice built entirely around unbundled, or limited scope, legal services. Instead of a full retainer that covers an entire case, clients hire the firm for specific pieces of help, whether that's reviewing a document, one legal coaching session, or a single court appearance. The firm points to research finding that most people in family court represent themselves, and that even limited legal assistance improves outcomes for self represented litigants. Appointments are held in Whitby, Oshawa, Barrie, Niagara, and Peterborough, backed up by virtual meetings, and the combined team of lawyers and clerks has more than 25 years of family law experience.

Birch Law was co-founded by Stephanie Ostrom, who has practiced exclusively in family law for more than 14 years and has appeared before the Ontario Court of Justice and the Ontario Superior Court on custody, property, and support matters. Family lawyer Keshia Maloney, who grew up in Oshawa, joined the practice after more than a decade in retail customer service and management, and went on to earn a law degree from the University of Leicester. The firm's own name shows up in its branding too: it calls its pricing commitment the Cost Transparency Guarantree.
