Particular attention is given to proposals on the improvement of norms on regulation (elimination) of crisis situations at the outer borders of the Commonwealth, as they have not previously found reflection on the scientific or lawmaking initiatives, despite the dynamic change of situation in the border territory. Methodology contains the combination of general scientific methods, such as systemic analysis, generalization of scientific concepts and normative material. The main conclusions lies in proposals on the improvement of model legislation in the area of ensuring security in the border territory, expresses in clarification of the concept “crisis situations” and its demarcation from the related concepts. Crisis situations should become one of the types of legal regime, and the heads of the states receive the direct consolidation of authorities on responding to ongoing changes at the external borders of the Commonwealth, which require the application of collective forces of the CIS member-states.
