I was under the impression that a well-plead complaint was sufficient if the defendant doesn't show up. What rule says you have to actually put on a case to get a default judgment?
It's a two step process. First your get the default entered if they don't respond, then you ask for judgment for damages. Maybe that's where the confusion lies. The default is entered by request almost automatically if they don't respond. Getting your judgment for damages requires evidence to prove your case.
