(a) The presiding judge of each administrative judicial region, after conferring with the judges of courts in the region having jurisdiction of Title IV-D cases, shall determine which courts require the appointment of a full-time or part-time associate judge to complete each Title IV-D case within the time specified in this subchapter.
(b) If the presiding judge of an administrative judicial region determines under Subsection (a) that the courts in the region require the appointment of an associate judge, the presiding judge shall appoint an associate judge from a list of the qualified applicants who have submitted an application to the office of court administration. Before making the appointment, the presiding judge must provide the list to the judges of the courts from which cases will be referred to the associate judge. Each judge may recommend to the presiding judge the names of one or more applicants for appointment. An associate judge appointed under this subsection serves for a term of four years from the date the associate judge is appointed and qualifies for office. The appointment of an associate judge for a term does not affect the at-will employment status of the associate judge. The presiding judge may terminate an appointment at any time.

(b-1) Before reappointing an associate judge appointed under Subsection (b), the presiding judge must notify each judge of the courts from which cases will be referred to the associate judge of the presiding judge’s intent to reappoint the associate judge to another term. Each judge may submit to the presiding judge a recommendation on whether the associate judge should be reappointed.
(c) An associate judge appointed under this subchapter may be appointed to serve more than one court. Two or more judges of administrative judicial regions may jointly appoint one or more associate judges to serve the regions.
(d) Except as provided under Subsection (e), if an associate judge is appointed for a court under this subchapter, all Title IV-D cases shall be referred to the associate judge by a general order for each county issued by the judge of the court for which the associate judge is appointed, or, in the absence of that order, by a general order issued by the presiding judge who appointed the associate judge. Referral of Title IV-D cases may not be made for individual cases or case by case.
(e) If a county has entered into a contract with the Title IV-D agency under § 231.0011, enforcement services may be directly provided in cases identified under the contract by county personnel as provided under § 231.0011(d), including judges and associate judges of the courts of the county.
