The 1997 Rules of Civil Procedure

Section 1

A person who has a legal interest in the matter in litigation, or in the success of either of the parties, or an interest against both, or is so situated as to be adversely affected by a distribution or other disposition of property in the custody of the court or of an officer thereof may, with leave of court, be allowed to intervene in the action.

The motion to intervene may be filed at any time before rendition of judgment by the trial court. A copy of the pleading-in-intervention shall be attached to the motion and served on the original parties. (2)

Section 3

The intervenor shall file a complaint-in-intervention if he or she asserts a claim against either or all of the original parties, or an answer-in-intervention if he or she unites with the defending party in resisting a claim against the latter. (3a)

Section 4

The answer to the complaint- in-intervention shall be filed within fifteen (15) calendar days from notice of the order admitting the same, unless a different period is fixed by the court. (4a)
