MacLean Law is a top-tier Western Canadian boutique family law litigation firm that has focused on complex, high-stakes family law matters since 1983. The firm's practice is centered on ultra-high-net-worth (UHNW) cases involving sophisticated financial structures, international assets, jurisdictional disputes, and complex legal issues. With a team of 18 lawyers, MacLean Law represents entrepreneurs, business owners, professionals, executives, and other high-net-worth individuals in matters relating to separation, divorce, child and spousal support, the division of worldwide family property and business interests, marriage and cohabitation agreements, and international family law disputes.

MacLean Law regularly represents clients in negotiated settlements, mediations, interim applications, trials, and appeals. The firm is also home to one of Canada's largest family law teams with Mandarin and Cantonese language capabilities, enabling it to serve a diverse international clientele.

MacLean Law has earned a reputation for handling some of the most complex and precedent-setting family law matters in Canada.

Partner Fraser MacLean gained national attention for exposing Canada's first reported legal AI "hallucination" in court proceedings.
