The plaintiff shall serve his/her reply to a counterclaim thus denominated in the reply, within ten (10) days after service of the answer or, if a reply is ordered by the court, within ten (10) days after service of the order, unless the order provides otherwise. When the Commonwealth of Puerto Rico, its officials, or any of its instrumentalities, other than a public corporation, and the municipalities of Puerto Rico are parties to a complaint, any party shall serve its answer to the complaint, its answer to a cross-claim against it, or its reply to a counterclaim, within an unextendable term of sixty (60) days after being served with copy of the summons and complaint.
