William J. Dorsey


William Dorsey focuses his practice on high-stakes commercial disputes involving commercial finance, real estate, M&A, and intellectual property.

Will represents many of the nation’s leading lenders in cases involving intercreditor disputes, breach of credit agreements, guaranty enforcement, lender liability claims, and lien priority fights. He also represents commercial lenders in bankruptcy litigation matters, including cash collateral disputes, preference and fraudulent transfer actions, claim objections, plan confirmation, and lift stay motions.

Will has handled foreclosures of industrial, retail, hotel, condominium, and condo-hotel projects across the country, including coordination of multi-state foreclosures. In addition, Will negotiates and documents forbearance agreements and deeds in lieu of foreclosure; litigates construction defect and mechanics lien claims on behalf of lenders, title insurance companies, and property owners; and prosecutes and defends complex commercial lease disputes on behalf of large institutional lenders and commercial landlords and tenants. He has served as a court-appointed attorney to bankruptcy examiners.

Will also represents buyers, sellers, and lenders in contested M&A transactions and frequently provides transaction-related advice.

In the area of intellectual property litigation, Will concentrates his practice on disputes involving unfair competition, trade secret, and trademark infringement.

Will has co-authored articles on the mortgage foreclosure process and landlord-tenant disputes for the Illinois Institute of Continuing Legal Education.
