A member of the Nebraska State Bar Association may participate in a law firm intending to engage an attorney as "of counsel" as long as the designated "of counsel" attorney and the law firm maintain a close and continuing relationship. Also, the relationship may not be formed solely for the purpose of being a forwarder and receiver of legal business and must not be allowed to evolve into such a relationship. Further, there do not appear to be any provisions which would prohibit a law firm from designating a lawyer, who is a probationary partner-to-be as "of counsel".
