Protecting Legacies and Resolving Disputes

Estate Litigation for Complex Estates and Family Wealth
When significant resources, family relationships, and business interests intersect, estate disputes are rarely simple. They demand more than technical litigation skills; they require strategic judgment, financial insight, and the ability to navigate emotionally charged dynamics without losing sight of long-term outcomes.
Lerners represents individuals, families, fiduciaries, and business owners in complex estate litigation and other high-stakes estate disputes in Ontario. We provide integrated, outcome‑focused guidance designed to protect value, manage risk, and preserve what matters most, whether through early resolution or decisive advocacy.
Strategic Advocacy When the Stakes Are HigH
Estate litigation often arises from high-risk scenarios: unclear or outdated planning, questions of capacity or influence, blended families, significant private assets, or disputes over control of family enterprises. Our role is to bring clarity to uncertainty by assessing legal merits, identifying leverage points, and guiding clients toward solutions that align with both immediate objectives and long-term legacy considerations.
An Integrated Approach to Estate Disputes
Early Risk Assessment and Strategic Planning
We begin by evaluating the strength of claims, evidentiary risks, procedural strategy, and financial exposure, alongside the broader family, business, and reputational context. This allows clients to make informed decisions from the outset
Focused Advocacy and Resolution Planning
Whether advancing a court application, pursuing negotiation or mediation, or preparing a matter for trial, we tailor our litigation strategy to our clients’ goals, timelines, and risk tolerance.
Coordination with Advisors and Business Counsel
Estate disputes often intersect with corporate governance, tax planning, valuations, and ongoing business operations. We work closely with accountants, corporate counsel, wealth advisors, and other professionals to ensure a fully integrated approach.
Where disputes arise from succession or planning issues, we work closely with our Wills and Estates colleagues to ensure continuity of advice and long-term solutions.
