What is a complaint-in-intervention?

What is a complaint-in-intervention? INTERVENTION is a legal proceeding by which a person who is not a party to the action is permitted by the court to become a party by intervening in a pending action after meeting the conditions and requirements of the Rules of Court.

If the purpose of the motion for intervention is to assert a claim against either or all of the original parties, the pleading shall be called a COMPLAINT-IN-INTERVENTION.

The intervenor shall file a complaint-in-intervention if he asserts a claim against either or all of the original parties, or an answer-in-intervention if he unites with the defending party in resisting a claim against the latter. (Rule 19, Sec. 3)

The answer to the complaint-in-intervention shall be filed within fifteen (15) days from notice of the order admitting the same, unless a different period is fixed by the court. (Rule 19, Sec. 4)
