Families and individuals with privately held businesses or family offices need all of the tax, succession planning, complex financial and litigation services offered to public corporations, tailored to their own circumstances. Our team's experience covers a wide range of disciplines so that clients receive comprehensive support to address evolving and unexpected issues.

An interdisciplinary way to meet goals

Katten's Private Client Services group spans the breadth of the firm. We understand that doing transactional work for a private client also necessitates considering the personal implications of that work. Our clients include closely held businesses, large families, wealthy individuals and family offices. Our interdisciplinary team, made up of attorneys who handle trusts and estates, real estate, tax, litigation, corporate, financial services and intellectual property issues, comes together whenever needed to advance clients' personal and business goals.

A clear-sighted approach to change

Privately held companies and individuals are working across international boundaries as never before and may face increasing regulation along with concerns about personal and business privacy. Change is now a constant, and our attorneys are ready to respond to anything from new governmental directives to altered financial and personal situations to family controversy. Our team works to protect private clients no matter the challenge, whether they are international investors seeking stability in the United States, creative artists enforcing intellectual property rights or individuals wishing to protect assets for future generations and to provide planning flexibility for their families now and in the future. As a client notes, "They're creative, they're energetic and they are advocates to their clients. . . . They're also incredibly thorough and there's a history and continuity that tells you what they can deliver" (Chambers HNW 2018, New York, Private Wealth Disputes).

"Katten is my go-to US firm for private client issues. They are always thorough, responsive, and commercially aware. Josh Rubenstein is simply superb."
