Maura Yusof (Of Counsel)


Maura’s practice spans a wide variety of litigation – from commercial disputes to medical malpractice and product liability claims to employment law. Her primary areas of practice include commercial litigation, product liability, construction and premises liability, healthcare, cannabis business & law, and medical malpractice defense. As a primary focus of her commercial practice, she has worked on several cases related to retail sales tax sourcing litigation. Her practice also encompasses large loss property subrogation matters pending throughout the United States and internationally. She has mediated and arbitrated numerous cases, including a three-week arbitration in Tokyo, Japan, that resulted in a multi-million dollar recovery for a construction defect matter, which arbitration award the Japanese courts affirmed on appeal. Her practice has involved various types of property damage claims, including construction defects, product defects, fires, explosions, and boiler and turbine failures. The nature of her practice has required regular analysis of contract documents, including whether exculpatory provisions and limitations of liability are enforceable based on the applicable state's law. In the subrogation area, her experience also includes obtaining recoveries arising out of workers’ compensation claims.

Maura began her legal career with Heyl Royster in 2002, when she worked at the firm's Edwardsville office primarily representing corporate defendants in asbestos toxic tort litigation for serious injury cases pending in Madison County, Illinois, including product liability and premises liability claims. In 2004, Maura moved to Chicago and expanded her litigation practice to large loss property subrogation matters. In 2010, Maura returned to Heyl Royster to handle commercial litigation and other civil matters pending in Chicago as well as asbestos toxic tort claims.

Maura was born in Kabul, Afghanistan and speaks fluent Dari, a dialect of Persian.

Significant Cases

  • Hartney Fuel Oil Company v. Hamer 2013 IL 115130 Suit was filed by a retail sales taxpayer against our client, The Regional Transportation Authority (RTA), the Illinois Department of Revenue, and a Cook County municipality contending that the assessment of back sales taxes of $20+ million was incorrect. Ultimately, the RTA's position was upheld in the Illinois Supreme Court. While the taxpayer was not required to pay back taxes pursuant to the Taxpayer Bill of Rights, the Illinois Supreme Court invalidated existing regulations in adopting a "multi-factor test" as argued for by the RTA, a decision which had statewide application to sales tax sourcing favoring governmental entities such as our client.
