It’s a huge challenge to qualify the operation of an organised society’s needs especially because of the limited resources. The task above has put pressure on the states since the middle of the XXth century. To solve the previous problem the states started to find new, non-traditional, alternative tools, legal institutions which are able to include other sector’s resource (e. g. private sector’s) into the provision of the public duties. One of these alternative legal institutions is the Public-Private Partnership (PPP). The study tries to examine how PPP were used by Hungarian local governments in the last few years, with special regard to the changes of regulations.
