Pro hac vice is a legal term, which allows an attorney from one state to practice law in another state for a particular case. For example, a lawyer in Indiana may have a client who has a case pending in Illinois, and the client wants his Indiana lawyer to represent him in Illinois. An Indiana attorney can find a local Illinois attorney, have that attorney file an appearance, and then file for Permission for an Out-of-State Attorney to Provide Legal Services in Proceedings in Illinois. This allows the Indiana attorney to represent his client in Illinois. The Supreme Court of Illinois clearly defines the rules in The Supreme Court of Illinois Rule 707 (renamed as Permission for an Out-of-State Attorney to Provide Legal Services in Proceedings in Illinois).
