Trust, Estate & Tax Controversies
Sophisticated Strategies for Complex Disputes.
Our Approach
There are few attorneys who take the time to become true estate and trust litigators. It takes years of experience with a wide variety of cases, education regarding esoteric legal concepts and dedication. Our estate and trust litigation group does not trifle with other types of litigation – this is all that we do.
Disputes that arise from the death or incompetency of a family member require attorneys to offer practical, strategic advice. We help our clients avoid litigation whenever possible and zealously advocate for favorable settlements. When litigation is inevitable, we draw on a deep bench of trial experience to strive for favorable outcomes, even in the most contentious disputes.
Our fiduciary litigation and risk management experience allows us to protect and advocate for our individual and corporate fiduciary clients as they navigate complex family disputes. We provide critical advice on avoiding litigation as well as positioning our fiduciaries for a successful defense in the courtroom.
