Our Experience

Mintz Secures Resounding Victory in Multi-Venue Estate Dispute

Mintz attorneys from our Private Client and Complex Commercial Litigation practices successfully represented a client in numerous lawsuits and appeals brought by her stepson, who had no legally protected interest in his late father’s estate.

Our Approach

Trusts and estates disputes are personal. In cases where family dynamics are strained, emotions run high, and estate plans are complex, we take the time to get to know our clients and what matters to them. Our practice supports trustees, executors, personal representatives, and beneficiaries of high-value estates in resolving sensitive disputes over significant, multigenerational assets both in and outside of courts. We work collaboratively with accountants, investment advisors, family offices, and others to evaluate the total picture and understand the nuances of the assets at issue. At the start of any dispute, we evaluate each client’s goals and develop strategies to achieve them. With sensitive issues and family dynamics often at stake, we often reach favorable resolutions outside the courtroom, aiming to solve the problem at hand and anticipate and prevent future disputes. When settlement is not on the table, we shine as fierce advocates in probate, trial, and appellate courts.

Nationwide Reach

Our skilled, cross-office team of litigators has a nationwide scope of practice. We have decades of experience practicing in probate, civil, and appellate courts across the country, including those in Massachusetts, New York, California, Florida, and Alaska.
