The term "Waiting periods" in this section deal with the time that the court requires must pass from the time the divorce is filed, and the time that the Judge signs your divorce decree.
Arkansas law requires that thirty (30) days elapse from the filing of the Complaint and Summons or Waiver of Service of process and Entry of Appearance before a final judgment of divorce be entered. If your spouse signs the Arkansas "Waiver of Service of process and Entry of Appearance" immediately after you file the complaint then you can divorced in as little as 30 days.
The law further states that a party to the divorce may remarry immediately after the judgment of divorce is entered.
