News & Events

Mary M. Culley has facilitated the decision-making processes of individuals, families, and fiduciaries in Delaware and Pennsylvania in the areas of estate planning, estate and trust administration, and federal and state transfer taxation for over 25 years.

Estate and gift planning comprise a significant portion of Mary’s practice. She assists clients with estate plans designed to accomplish their personal goals and preserve wealth by minimizing transfer taxes and probate fees. She designs estate plans with the flexibility to adjust to subsequent changes in the estate tax law and/or the clients’ wealth.

Mary has extensive experience representing fiduciaries (executors, administrators, and trustees), and beneficiaries of estates and trusts. With the assistance of experienced paralegals, Mary guides even complex estates through the estate administration process in an efficient and timely manner.
