The practice of procedural acts outside the place of the process with foreign element is common, and that is possible thanks to the will of the States making the territoriality and sovereignty principle of the process not an impediment for the performance of fundamental diligences that allows to explain the controversy. This work is a brief vision about the Peruvian Private International Law System.

From the position assumed by our procedural legal ordering on the immediate application of the norm, even to the process in proceeding, it indicates that this one enters in use, or it's official the day after its publication, so that the acts that arise from its validity are under its frame of application. However, the procedural norm is applied immediately for processes that are initiated, even for the ones that are in process, but the rules of competition, the interposed impugning means, the procedural acts with execution principle and the terms that will have begun, will continue being treated by the previous norm.
