Indiana Code Title 33. Courts and Court Officers § 33-33-87-16

(1) A defendant is considered to have complied with the statute and rule requiring the filing of an answer upon entering the defendant's appearance personally or by attorney. An appearance is considered a general denial and preserves all defenses and compulsory counterclaims that may then be presented at the trial of the cause.

(2) If at the trial of the cause the court determines that the complaint is so vague and ambiguous that the defendant was unable to determine the nature of plaintiff's claim or that the plaintiff is surprised by a defense or compulsory counterclaim raised by the defendant that the plaintiff could not reasonably have anticipated, the court shall grant a continuance.

(3) The trial must be informal, with the sole objective of dispensing speedy justice between the parties according to the rules of substantive law, and may not be bound by the statutory provisions or rules of practice, procedure, pleadings, or evidence except provisions relating to privileged communications and offers of compromise.
