Best Law Firms by Practice Area

These firms were voted strongest in each practice area by associates working in that area at peer firms. Vault's 2021 Rankings are derived from Vault's Annual Associate Survey conducted between late January 2020 through early April 2020.
Survey Methodology

Each year, Vault ranks law firms in a variety of practice areas based on the perceptions of associates practicing in those areas. Associates were asked to vote for up to three firms they consider strongest in their practice areas and were not permitted to vote for their own firms. For example, associates who identified themselves as corporate attorneys were allowed only to vote in corporate-related categories (securities, financial services, etc.). Our rankings list the top firms in each area, as well as the total percentage of votes cast in favor of each ranked firm.

Vault ranked the following practice areas this year: Antitrust; Appellate Litigation; Banking & Financial Services; Bankruptcy/Restructuring; Clean Tech/Renewable Energy; Emerging Companies/VC; Energy, Oil, & Gas; Environmental Law; General Commercial Litigation; General Corporate Practice; Health Care; Intellectual Property; Intellectual Property Boutiques; International; Labor & Employment; Litigation Boutiques; M&A; Media, Entertainment, & Sports; Privacy & Data Security; Private Equity; Products Liability; Project Finance; Real Estate; Securities; Securities Litigation; Tax; and White Collar Defense & Internal Investigations.

Vault's 2021 Rankings are derived from Vault's Annual Associate Survey conducted between late January 2020 through early April 2020.
