A Texas Motion to Substitute Counsel is a legal document used to request a change of attorney in a court case. The motion must be filed with the court and must contain specific information about why the client believes a change of attorney is necessary. There are two types of Texas Motions to Substitute Counsel: Substitution of Counsel Due to Death or Disability and Substitution of Counsel for Other Reasons. In the former, the motion must include a certificate of death or disability of the attorney, while in the latter, the motion must include an affidavit from the client explaining the reasons for the request. Both types of motions must be accompanied by a certificate of service, which shows that the motion has been delivered to all the parties involved.
