What Honigman does

Honigman LLP is a private, full-service business law firm founded in 1948 and headquartered in Detroit, Michigan. The firm operates as a limited liability partnership with approximately 400 attorneys practicing across 60+ legal areas, making it one of the largest law firms in the United States by attorney count and the largest in Metro Detroit per Crain's Detroit Business 2026. Honigman maintains seven Midwest offices across Michigan plus Chicago and Washington DC, and an international practice through its wholly owned subsidiary Honigman Law Israel.

The firm's core service lines include Corporate (with M&A, Private Equity, Capital Markets and Securities), Litigation, Real Estate, Intellectual Property (Patent, Trademark and Copyright), Labor and Employment, Immigration, and Government Relations/Regulatory practices. Its Private Equity Practice is consistently ranked in the top 10 nationally by PitchBook and the firm has closed over 2,000 acquisition and divestiture transactions since January 2020, advising on more than $42 billion in deal value from 2024 to 2025. Honigman has invested in practice technology through firm-wide deployment of the Harvey AI platform, with broad-based adoption across associates and partners delivering measurable efficiency gains including deposition summaries completed in under a day that previously required two weeks.

Honigman generates revenue through traditional professional services billing (hourly, matter-based, and alternative fee arrangements) targeting enterprise clients including private equity firms, public and private companies, venture capital and growth equity investors, real estate developers, and technology and life sciences companies. Go-to-market relies on lateral partner hiring from major law firms in money-center cities, direct business development, and thought leadership through publications, events, and PR. The firm is Chambers USA 2026 Band 1 ranked in six practices with 33 leading attorneys, and Best Lawyers 'Best Law Firms' 2026 nationally ranked in 21 practice areas.
