A
special appearance is a term used in the
United States law of
civil procedure to describe a civil
defendant's appearance in the
court of another
state solely to dispute the
personal jurisdiction of the court over that defendant. Prior to the advent of this procedure, defendants had to either appear in the other state's court to defend the case on the merits, or not show up in court at all, and then mount a collateral attack on any
judgment rendered against them, when the
plaintiff came to the defendant's state to collect on the judgment. In a legal
catch-22, if the defendant appeared solely to contest jurisdiction, the court would then be permitted to assert jurisdiction based on the defendant's presence.
