Section 8-14-106 - Waiver of right to counsel - Writing - Procedure for acceptance(a) No person in this state shall be allowed to enter a plea in any criminal prosecution or other proceeding involving a possible deprivation of liberty when not represented by counsel, unless such person has in writing waived the right to the assistance of counsel.(b) Before a court shall accept a written waiver of the right to counsel, the court shall first advise the person in open court concerning the right to the aid of counsel in every stage of the proceedings. The court shall at the same time determine whether or not there has been a competent and intelligent waiver of such right, by inquiring into the background, experience and conduct of the person and such other matters as the court may deem appropriate. If a waiver is accepted, the court shall approve and authenticate it and file it with the papers of the cause, and if the court is one of record, the waiver shall also be entered upon its official minutes.
