Section 5712 - Default judgment(a) No judgment for the plaintiff shall be entered unless the court is satisfied, upon competent proof, that the defendant has received actual notice of the proceeding or, having abandoned the rental unit, cannot be found within the jurisdiction of the court after the exercise of reasonable diligence. Posting and first-class mail, as evidenced by a certificate of mailing, is acceptable as actual notice for the purposes of a default judgment.(b) A party may, within 10 days of the entry of a default judgment or a nonsuit, file a motion with the court to vacate the judgment and if, after a hearing on the motion, the court finds that the party has satisfied the requirements of Justices of the Peace Civil Rule 60(b), it shall grant the motion and permit the parties to elect a trial before a single judge or a jury trial. 70 Del.
