We work with clients from a wide variety of industries who are pursuing or defending claims in Delaware’s Court of Chancery, Superior Court, and District Court.
Our comprehensive services extend beyond the courtroom, focusing on negotiating practical solutions and employing alternative dispute resolution techniques whenever appropriate.

Delaware is home to business entities with operations and stakeholders from all over the world. When disputes arise, the Court of Chancery becomes the primary forum for resolving those disputes. Our corporate litigation lawyers are seasoned practitioners. We advise on control disputes, corporate governance issues, books and records demands, and breach of fiduciary duty allegations, with experience advocating for both the entity and the principal. Our team routinely handles expedited matters, often involving temporary restraining orders, in the Court of Chancery.
Our private wealth team advises and advocates for banks, trust companies, and individual trustees faced with fiduciary duty questions and disputes. Fiduciaries are subject to onerous legal duties and often manage substantial assets belonging to others. This precarious combination can expose fiduciaries to claims of mismanagement, imprudent investing, self-dealing, conflict of interest, failure to disclose, and other breaches of fiduciary duties. In addition, disputes can arise between trustees and beneficiaries regarding the construction of a trust. It is common for institutional and individual trustees to preempt such disputes and mitigate their risk by petitioning the court to interpret uncertain trust arrangements. Likewise, wills challenges require discretion and tact, and our team has decades of combined experience representing estates and beneficiaries in what can be sensitive litigation.
Our attorneys have comprehensive experience in representing and advising clients in various disputes which arise out of the acquisition, sale, development, use and enjoyment of commercial and residential real estate.
