Private Client Services

Arnold & Porter’s Private Client Services group provides an interdisciplinary approach to addressing the complex needs of wealthy individuals and families regarding their businesses, investments, wealth succession planning, and philanthropic activities. The group counsels clients on a wide variety of issues relating to estate planning, tax, real estate, family disputes, business organization, and succession planning. We have extensive experience in the creation and operation of family offices for the purposes of wealth preservation and asset protection planning. 

We strive to build long-term relationships with our individual and family clients by serving as a confidential sounding board. We review each client’s overall picture, from the protection of assets to issues of family harmony, and from philanthropic goals to the client’s tolerance for complexity and risk in tax planning. We operate with a “full service” mentality, working closely with other members of the client’s team of advisors, centralizing information to help obtain answers that are not only vetted by our team but are clear and actionable.
