With the changes of welfare paradigm and aging population, the conclusion of the Convention on the Rights of Persons with Disabilities and activities for introduction of adult guardianship system mainly promoted by organizations for the disabled helped a revision on the civil law to be passed in February 2011, and a new adult guardianship system was put into effect on July 1, 2013. In the process of the introduction, there were a lot of discussions and issues relating to the revision to the civil law, special law enactment, monism and pluralism, but the adult guardian system of a form of pluralism through the revision of the civil law was introduced in consideration of the legal system and reality of Korea. However, a form of monism was partially introduced by reflecting the contemporary situations such as the Convention on the Rights of Persons with Disabilities. Korean adult guardianship system is divided into adult guardianship, limited guardianship and specific guardianship depending on the range of a ward's behavioral ability and business scope, and the right of representation of the guardianship, and guardianship agreement signed in preparation for the future mental constraints such as dementia. The use of adult guardianship system has continuously been on the rise. However, due to the lack of publicity, public awareness and institutional devices, only the adult guardianship is rampant, and the use of limited guardianship, specific guardianship and guardianship agreement is not widely spread. Therefore, in order to activate the adult guardianship system in Korea, a lot of political agendas can be considered. First of all, however, it is required to maintain specific provisions and regulations to support wards or institutional procedures for using the system. In addition, there is a need to maintain provisions that can restrict the human rights of wards such as the consent to personal decisions or the limitation of voting rights that can violate the human rights of wards, along with the maintenance of provisions regarding the disqualification of adult ward or limited ward which are present in more than 300 laws.
