Do we have to attend a juvenile intake?

Without knowing why they want juvenile intake, I can't answer this question. You have not told me everything.

You and your child are required to go to the juvenile intake conference. Court intake service conference is; a. Where the juvenile is diverted to a court intake service conference, notices of the conference shall be sent to the juvenile and his parents or guardian and to the complainant or victim. The parties may be requested to bring to the conference all pertinent documents in their possession, including medical, social, and school records. b. In determining the appropriate resolution of a complaint, the following factors are considered by court intake services: (1) The seriousness of the alleged offense or conduct and the circumstances in which it occurred; (2) The age and maturity of the juvenile; (3) The risk that the juvenile presents as a substantial danger to others; (4) The family circumstances, including any history of drugs, alcohol abuse or child abuse on the part of the juvenile, his parents or guardian; (5) The nature and number of contacts with court intake services and the court that the juvenile and his family have had; (6) The outcome of those contacts, including the services to which the juvenile or family have been referred and the results of those referrals; (7) The availability of appropriate services; (8) Any recommendations expressed by the victim or complainant, or arresting officer, as to how the case should be disposed; (9) Whether diversion can be accomplished in a manner that holds the juvenile accountable for the conduct; (10) The impact of the offense on the victim or victims; (11) The impact of the offense on the community; and (12) Any information relevant to the offense in any case where the juvenile is charged with an act, which if committed by an adult would constitute prostitution in violation of any offense, which the juvenile alleges is related to the juvenile, being a victim of human trafficking. c. Each juvenile shall be reviewed without a presumption of guilt. The intake conference shall be concerned primarily with providing balanced attention to the protection of the community, the imposition of accountability for offenses committed, fostering interaction, and dialogue between the offender, victim and community and the development of competencies to enable the juvenile offender to become a responsible and productive member of the community. In addition, the conference shall be concerned with preventing more serious future misconduct by the juvenile offender by obtaining the cooperation of the juvenile and his parents or guardian in complying with its recommendations. The court may schedule a hearing where the complainant or victim objects to the recommendations from the conference. d. The resolution from the conference may include but shall not be limited to counseling, restitution, referral to appropriate community agencies, or any other community work programs or other conditions consistent with diversion that aids in providing balanced attention to the protection of the community, the imposition of accountability for offenses committed, fostering interaction and dialogue between the offender, victim and community and the development of competencies to enable the juvenile offender to become a responsible and productive member of the community, provided that: (1) Obligations imposed because of the intake conference shall be an order of the court approved by the presiding judge and shall be set forth in writing and may not exceed six months. The juvenile and his or her parents or guardian shall receive copies, as shall any agencies providing services under the agreement; (2) The court intake service worker shall inform the juvenile and the juvenile's parents or guardian in writing of their right to object at any time prior to their written agreement to the facts or terms of the intake conference decision, and if objections arise, the intake service worker may alter the terms of the proposed agreement or refer the matter to the presiding judge who shall determine if the complaint will

Your question is a bit sparse on the facts, but the fact that you, I assume as parents, have committed to meet with a juvenile intake specialist and answer questions would certainly signaled to me then seeking counsel would be a very wise thing to do. The police and juvenile authorities are not a friend of your child and are seeking most probably to find him or her guilty of some infraction. I would confer with an attorney before the appointment and determine the with their counsel whether or not they should be present representing your child.

Yes. No attorney yet.

Since you tell me absolutely nothing about what the intake is for and what the charges are... I have no idea. It may be a good idea to consult with an attorney.
