What is a default judgment and how do you fight it?

A default judgment is entered when a defendant fails to respond to a lawsuit within the required time, allowing the plaintiff to win without a contested hearing on the merits. It can often be challenged by filing a motion to set it aside, typically by showing good cause — such as improper service, excusable neglect, or a valid defense — and by acting promptly once the defendant learns of the judgment.

How a Default Judgment Happens

When a lawsuit is filed, the defendant is generally required to file a formal response within a set deadline after being served. If no response is filed, the plaintiff can ask the court to enter a default, and eventually a default judgment, without the case ever being contested on its merits.

Default judgments often happen because a defendant was unaware of the lawsuit, moved without updating their address, misunderstood the deadline, or simply ignored the paperwork, assuming incorrectly that it would resolve itself or was not legitimate.

Grounds for Setting Aside a Default Judgment

Courts generally allow a default judgment to be challenged through a motion to set it aside, most commonly on grounds like improper or defective service of the lawsuit, excusable neglect in missing the deadline, or newly discovered evidence that could not have been raised earlier.

Courts typically also want to see that the defendant has a legitimate defense to the underlying claim — simply showing a procedural excuse for missing the deadline is often not enough on its own if the defendant has no real defense to offer once the case is reopened.

The Process of Fighting a Default Judgment

Fighting a default judgment usually starts with filing a formal motion in the same court that entered it, laying out the reason the default should be set aside and, where required, describing the defense that would be raised if the case were reopened. Courts generally expect this motion to be filed promptly after the defendant learns of the judgment.

If the motion is granted, the case typically proceeds as if the default had not occurred, allowing the defendant to respond and litigate the claim on its merits. If the motion is denied, the judgment generally remains enforceable, and the defendant's options may then shift toward appeal or negotiating with the judgment creditor.

What to Do If You're Served With a Lawsuit

The most effective way to avoid a default judgment is to respond to a lawsuit within the required deadline, even if that response is simply to seek more time or consult an attorney about the best approach. Deadlines to respond are often shorter than people expect, so prompt action matters.

Anyone who discovers they already have a default judgment against them should move quickly, since delay can itself work against a motion to set it aside — courts generally look less favorably on requests filed long after the defendant became aware of the judgment.

Related questions
How much time do I have to challenge a default judgment?
Deadlines vary by jurisdiction and are often relatively short once a defendant becomes aware of the judgment. Acting as quickly as possible after discovering a default judgment generally improves the chances of successfully challenging it.
Will a court always set aside a default judgment if I ask?
No. Courts generally require a valid legal basis, such as improper service or excusable neglect, along with a showing that a real defense exists. A default judgment is not automatically reversed simply because the defendant asks.
