The party who is the subject of a protective order may request a hearing from the court to contest the allegations in the petition and ask the court to reverse the issuance of the order.
If the court denies the initial ex parte petition, the court will likely set the petition for a hearing within 30 days or so. The party filing the petition will need to come forward with their witnesses and documents to support their petition. If a divorce is pending, the protective order court will likely transfer the case to the divorce court to ensure that all issues are heard in one forum.
