A significant factor contributing to the backlog of courts is the delay and difficulty in serving of summons. Addressing issues arising from many important issues of justice requires good cooperation between experts and judges. In courts dealing with lawsuits, petitions, complaints and various applications, it is important for the court to summon the parties to court, usually by way of notice, summons and search. This process is called "service of process" and is expected to send legal information to the relevant persons.
