Arizona Substitution of Attorney is a legal document that is used to appoint a new attorney to handle a case in place of the original attorney. It is often used when the original attorney no longer wishes to handle the case or is otherwise unable to do so. There are two types of Arizona Substitution of Attorney: voluntary and involuntary. Voluntary Substitution of Attorney is used when a client voluntarily wishes to change attorneys or is transferring an active case to another attorney. This type of substitution must be agreed upon by both the original and new attorneys. Involuntary Substitution of Attorney is used when an attorney is no longer able to handle a case, either due to death, disability, or other reason. This type of substitution does not require the consent of the original attorney. To complete an Arizona Substitution of Attorney, the new attorney must complete the Substitution of Attorney form and submit it to the court. The form must include details such as the name of the original attorney, the name of the new attorney, the case number, and a signature from the new attorney. The court must approve the Substitution of Attorney before the new attorney can begin to handle the case.
