Rule 1-015(C) NMRA 2001 allows the amendment of a complaint to relate back to the date the original complaint was filed if certain conditions are met Under Rule 1-015(C), it is not enough that a defendant is aware that an action may be brought by the plaintiff. Rather, Rule 1-015(C)(1) requires that a plaintiff prove that the defendant "has received notice of the institution of the action." In Macias v. Jaramillo, 2000 NMCA 86, 7-29, 129 N.M. 578, 11 P.3d 153, the Court held that the plaintiff had satisfied this requirement where: (1) the plaintiff had filed a claim against the defendant insurance company immediately after an accident; (2) he had corresponded with the insurance company and other defendants for several months prior to filing the original complaint; (3) the insurance company knew that the complaint had been filed; (4) the insurance company retained counsel to defend itself and the original defendants.
