Mannion Prior, LLP is Pennsylvania’s premier fiduciary litigation boutique. We pursue, defend, and provide advice on issues involving the standards of care applicable to fiduciaries such as trustees, executors, guardians, charitable organizations, banks, trust companies, partners, attorneys, and officers and directors of corporations.

We focus our practice primarily in the Orphans’ Court Division of the Court of Common Pleas, and have obtained successful results in will contests, trust and trustee litigation, fee and commission disputes, estate litigation, and guardianship and incapacity proceedings.

We also pursue and defend select business litigation matters in Pennsylvania and federal courts, including non-compete and non-solicitation litigation, severance and commission disputes, software implementation issues, and contractual disputes.

Our attorneys are well qualified to serve your needs, and maintain the highest standards of professionalism in their work. For a broader view of who we are, please read our Firm Overview .
