Robert H. Wellen is an attorney based in Washington, DISTRICT OF COLUMBIA. The practice focuses on Tax and Tax Litigation.
Bob grew up in Jersey City, New Jersey. He graduated from Yale College in 1968 and Yale Law School in 1971. As a law student, he assisted Professor Boris I. Bittker in editing a new edition of Federal Income Taxation of Corporations and Shareholders.
Bob served on active duty in the U.S. Navy Judge Advocate General’s Corps. His work included representing Naval personnel at courts martial and administrative hearings, general legal assistance to Naval personnel and drafting legal opinions for the Judge Advocate General. As a highlight, he had the opportunity to work on briefing and arguing a case in the U.S. Supreme Court involving the Constitutional right to counsel in courts martial. While on active duty, he obtained an LL.M. (Taxation) from Georgetown University Law Center.
When he completed his active duty in the Navy, Bob joined the Washington office of Fulbright & Jaworski LLP, where he began his tax law career. He later became a partner of that firm. While at Fulbright & Jaworski, he worked principally on corporate transactions, including the spin-off by The Coastal Corporation (later acquired by El Paso Corporation) of Valero Corporation, currently the largest oil refiner in the U.S., and the work-out of the Great Plains Coal Gasification project.

He has also represented clients in tax controversies with I.R.S. in audit, appeals and litigation. These controversies have involved complex corporate and consolidated return issues, including issues relating to stock redemptions, debt workouts and joint ventures.
Due to his national reputation, Bob has been tapped as an expert witness on corporate tax in cases in litigation in state and Federal courts and in arbitration. He has also served as arbitrator in a number of disputes involving tax sharing agreements between parties to acquisitions and spin-offs.
Bob’s articles on corporate tax subjects have been published in the Practising Law Institute volumes on corporate transactions, Tax Notes, Journal of Taxation, Taxes and other publications.
