Some firms also use the term to refer to attorneys hired on a temporary basis to assist with a particular case.

Compensation[edit]
The average annual base salary for "of counsel" or "special counsel" in the United States between 2003 and 2009 was US$216,019 (with salary varying depending on size/reputation of the firm, its location, and the attorney’s experience).[5] At highly prestigious law firms, an "of counsel" or "special counsel" may make as much as US$375,000 per year.[2]
