Any party to the proceeding may request termination of the GAL pursuant to the following statute:
(5) Termination and extension of appointment. The appointment of a guardian ad litem under sub. (1) terminates upon the entry of the court's final order or upon the termination of any appeal in which the guardian ad litem participates. The guardian ad litem may appeal, may participate in an appeal or may do neither. If an appeal is taken by any party and the guardian ad litem chooses not to participate in that appeal, he or she shall file with the appellate court a statement of reasons for not participating. Irrespective of the guardian ad litem's decision not to participate in an appeal, the appellate court may order the guardian ad litem to participate in the appeal. At any time, the guardian ad litem, any party or the person for whom the appointment is made may request in writing that the court extend or terminate the appointment or reappointment. The court may extend that appointment, or reappoint a guardian ad litem appointed under this section, after the final order or after the termination of the appeal, but the court shall specifically state the scope of the responsibilities of the guardian ad litem during the period of that extension or reappointment. 767.407 (4m) - https://docs.legis.wisconsin.gov/statutes/statutes/767/V/407
The purpose of the GAL is to help facilitate custody agreements in the best interests of the child; so if the GAL is actually obstructing the process the court is more likely to appoint an alternative GAL. One may submit a declaration of the dates of missed appointments.
