Daniel L. Rottinghaus — Principal

Areas of Practice

Dan is a litigator with the Firm with expertise in construction, real estate, insurance, and tort litigation. He started with the Firm in 1994 and has been an equity partner of the Firm and one of its principals since 1995. His practice focuses on litigating complex cases, including multi-party, construction-defect, mass tort, and class litigation. Though his specialty is the litigation of construction defect claims, he regularly handles disputed complex trials involving insurance contracts and the interpretation of statutes, policies of insurance, partnership agreements, and contracts. Virtually every case he handles involves disputed provisions of insurance coverage and the scope of such coverage as the same bears directly on resolution of the issues in dispute. His ability to reduce complicated factual situations into manageable legal positions makes him very adept at resolving, construction-defect claims that involve a significant number of parties, a multitude of records, and understanding the cross-over between association, contract, tort, real estate and insurance law.

He practices in both the state and Federal courts. He has litigated cases primarily in California, but he has also been counsel for clients in cases litigated in the District of Columbia, Florida, Massachusetts, Nevada, New York, and Hawaii. Rottinghaus' scholarship and practice in complex litigation is informed by the experience he gained litigating claims under international law while an attorney serving in the U.S. Department of State and representing the United States in litigation before the Iran-United States Claims Tribunal in The Hague, Netherlands. As an attorney adviser in the Office of the Legal Adviser of the U.S. Department of State he defended the interests of the United States in Case No. B/1 (Iran's Foreign Military Sales Claims) and other claims asserted by the Government of Iran arising out of the resolution of America's hostages. Prior to that time, Rottinghaus was a Captain and attorney in the U.S. Army serving in the Judge Advocate General's Corps for the 1st Infantry Division and the 2nd Infantry Division where he defended U.S. soldiers in criminal actions in the United States and overseas. In 2004, he litigated to settlement before the U.S Department of Justice's September 11 Compensation Fund two claims for victims killed in the terrorist attacks on the World Trade Center.
