In most, if not all, states, you have a certain time to respond to a lawsuit with an "Answer" filed with the court (typically 20, 23, or 30 days after service of the Complaint and Summons). If the time elapses, the Plaintiff can motion the court for a "default judgment" in their favor - basically getting a judgment against you without having to prove anything with evidence, testimony, etc.
