A Motion to Vacate Default Judgment in Alaska is a legal document used to set aside a default judgment issued against a party who failed to defend against a lawsuit. This type of motion can be filed in the court where the judgment was issued, and is used to ask the court to cancel or change the existing judgment. In Alaska, there are two types of Motions to Vacate Default Judgment: Motions to Vacate Default Judgment Based on Legal Error, and Motions to Vacate Default Judgment Based on Excusable Neglect. Motions to Vacate Default Judgment Based on Legal Error are used to challenge the legality of the default judgment, and can be used if the court made an incorrect ruling or if the judgment was not in accordance with the law. On the other hand, Motions to Vacate Default Judgment Based on Excusable Neglect are typically used if the defendant was unable to respond to the lawsuit for a valid reason. In order to be successful, the defendant must prove that they had a valid excuse for not responding and that the excuse was beyond their control.
