4:5-5. Effect of Failure to Deny

Allegations in a pleading which sets forth a claim for relief, other than those as to the amount of damages, are admitted if not denied in the answer thereto. In every action brought upon a negotiable instrument, the authenticity of any signature or endorsement thereon shall be taken to be admitted unless the same is put in issue by the pleadings. Allegations in any answer setting forth an affirmative defense shall be taken as denied if not avoided in a reply; issue shall be deemed to have been joined upon allegations in an answer setting forth other matters. Allegations in a reply shall be taken as denied or avoided, and any defense thereto in law or fact may be asserted at trial.
