About Arnstein & Lehr LLP

Arnstein & Lehr LLP is one of the country’s oldest and most respected law firms. Since its founding in 1893, we have been serving clients – large and small – throughout the United States and in many foreign countries. Arnstein & Lehr today offers clients a sophisticated, full-service practice that addresses their diverse and complex needs with vision, expertise and a commitment to quality and service.

Our Lawyers Are Trusted Advisors

Our attorneys work collaboratively to assist clients in achieving personal and business goals, structuring, negotiating and closing transactions, and handling disputed matters. We are our clients’ trusted advisors and our goal in every matter is to deliver excellent legal counseling. We strive to know our clients’ businesses and be the best partner each client could have.

We practice in five main service groups – Business, Litigation, Local Government, Tax and Estate Planning, and Real Estate. Please review the detailed information about our practices on this website.

We Build Client Relationships that Last

Arnstein & Lehr lawyers have historically developed and maintained enduring relationships with clients. Through the years, we have attracted lawyers with a similar philosophy of client service and loyalty. The result has been steady, continuing growth and a reputation for excellence in providing quality representations.

One of our secrets to success: A keen awareness of our clients’ business goals.

As a mid-sized law firm, we have the breadth and depth of legal talent to address our clients’ and prospective clients’ needs. We offer clients a highly competitive rate structure as well as a nimbleness that allows us to move rapidly when a client is facing a crisis. Many law firms can claim to have these attributes. But most of the others do not have 120-plus years of experience working with clients around the globe.

Please reach out to us and allow our lawyers to demonstrate how we deliver quality legal counsel and service.


We also recognize our collective diversity as an asset that strengthens legal excellence, leadership, collaboration, and community. At Arnstein & Lehr, we foster a professional environment that values attorneys and staff of all backgrounds. In addition, we are committed to cultivating a rich, dynamic workplace in which individuals are respected for their uniqueness. Read more about our commitment to diversity.
