Inter-municipal cooperation is a specific phenomenon in local public administration across the world. It is a concept that has been applied globally, particularly in countries with more fragmented local government. Often its implementation helps to solve problems or challenges associated with the existence of fragmented public administration in the delivery of public services. From the existing investigations dedicated to this specific issue carried out in the Czech Republic, it appears that this model of local public administration is very often mentioned in this country; however, its real use in the territory by public administration even after a long period of its existence in this country still has a great potential for development and use even in comparison with how it is abroad. The aim of this article is to identify and characterise the motivation and willingness of municipalities in the country to cooperate in order to meet the current conditions.
