Estate litigation is one of the most deceptively complex areas of civil practice. What may begin as a straightforward disagreement over a will or trust can quickly evolve into a highly charged dispute involving family dynamics, fiduciary obligations, and intricate procedural rules. For lawyers who do not regularly practice in this area, the risks of missteps—both legal and emotional—are significant.

Common estate disputes include will challenges, dependent support claims, contested powers of attorney, and estate trustee accounting applications. Each of these matters engages not only the Succession Law Reform Act and Estates Act, but also the Rules of Civil Procedure and evolving case law governing fiduciary duties, undue influence, capacity, and costs. The procedural nuances—such as strict limitation periods, evidentiary presumptions, and mandatory mediation requirements—demand specialized knowledge and experience.

Beyond the legal framework, estate litigation is deeply personal. Clients are often grieving, and their disputes frequently involve long-standing family tensions. Lawyers must navigate these sensitivities while advancing their client’s position forcefully and efficiently. What’s needed is a steady hand—one that balances empathy with firm advocacy and strategic insight.
