 The definition of the practice of law is established by law and varies from one jurisdiction to another. In order to protect the public, persons not admitted to practice law in Colorado cannot hold themselves out as lawyers in Colorado or as authorized to practice law in Colorado. Rule 5.5(a)(1) recognizes that C.R.C.P. 20, C.R.C.P. 221, C.R.C.P. 221.1, and C.R.C.P. 222 permit lawyers to practice law in accordance with their terms in Colorado without a license from the Colorado Supreme Court. Lawyers may also be permitted to practice law within the physical boundaries of the State, without such a license, where they do so pursuant to Federal or tribal law. Such practice does not constitute a violation of the general proscription of Rule 5.5(a)(1).
 Paragraph (a)(3) does not prohibit a lawyer from employing the services of paraprofessionals and delegating functions to them, so long as the lawyer supervises the delegated work and retains responsibility for their work. See Rule 5.3. Likewise, it does not prohibit lawyers from providing professional advice and instruction to nonlawyers whose employment requires knowledge of law; for example, claims adjusters, employees of financial or commercial institutions, social workers, accountants and persons employed in governmental agencies. In addition, a lawyer may counsel nonlawyers who wish to proceed pro se.
 A lawyer may employ or contract with a disbarred, suspended lawyer or a lawyer on disability inactive status, to perform services that a law clerk, paralegal or other administrative staff may perform so long as the lawyer directly supervises the work. Lawyers who are suspended but whose entire suspension has been stayed may engage in the practice of law, and the portion of the Rule limiting what suspended lawyers may do does not apply.
 The name of a disbarred lawyer or a suspended lawyer who must petition for reinstatement must be removed from the firm name. A lawyer will be assisting in the unauthorized practice of law if the lawyer fails to remove such name.
 Disbarred, suspended lawyers or lawyers on disability inactive status may have contact with clients of the licensed lawyer so long as such lawyer and the licensed lawyer provide written notice to the client that the lawyer may not practice law. Written notice to the client shall include an advisement that the person may not give advice or engage in any other conduct considered the practice of law. Proof of service shall be maintained in the licensed lawyer's file for a minimum of two years.
 Separate and apart from the disbarred, suspended or disabled lawyer's obligation not to practice law, the licensed lawyer who employs or hires such person has an obligation to directly supervise that individual.
