Civil Procedure II
Default
Default is a failure to submit an answer within the time allowed.
A defendant in America has 21 days after being served to submit an answer or 60 days if he waived service under Rule 4(d). Rule 12(a)(1)(A).
The US government always gets 60 days. Rule 12(a)(2)
If a Rule 12 motion is filed, the deadline for an answer is postponed to 14 days after notice of the court's response. Rule 12(a)(4).
Entering a Default Judgment
A clerk must enter a default when the plaintiff requests it with an affidavit stating an amount of damages computable with certainty by the clerk and that the defendant defaulted. Rule 55(b)(1).
In all other cases, the court enters default after the plaintiff files a motion and serves the other side.
