慣習法上 法定地上權에 관한 硏究 : 判例와 入法論을 中心으로 = Legal Superficies on customary Law : The central Point Judgement and Legislation Discussion

관습법상 법정지상권의 판례와 입법 방향을 연구했다.

Our civil law defines the land as real estate and building as independent and separate real estate. It is different from the European legislature in that the latter recognizes the land and buildings as real estate. Buildings should be involved in the land use in nature. They should have an inevitable relation with the right to use the land to assure the value as independent real estate. There are cases that the land and buildings belong respectively to different persons in legislature system that treats the land and buildings as independent. At this time, several problems may arise on how to adjust the interest in the right to use the land for existence of the buildings.

The legal superficies is a system to solve the problems according to the law and the legal superficies on customary law is to solve problems according to the customary law. The legal superficies on customary law is a system to supplement a fault in treatment of the land and buildings as independent and separate. When the land and buildings that belong to the same person are owned by different persons and there is an inevitable case that buildings owners do not have the right to use the land, the legal superficies on customary law is a way to solve the problem. The system is recognized as customary law by precedents.

The legal superficies can prevent complicating problems caused by poor control of owners at the age when a concept about ownership that the land and buildings are separate and independent real estate was not established. Also the system stopped removal of buildings by helping owners of buildings to use the land legally. It has made a great contribution to realization of social and economic interests by maintaining the value as buildings. Nevertheless, the legal superficies on customary law has a poor theoretical basis, unclear factors of establishment and imperfect public system, which cause an obstruction in safe transaction.

Therefore, the legal superficies on customary law should be put on a firm basis. In this study, preface presents a problem followed by meaning of the legal superficies on customary law, factors of establishment, contents, transfer and problems. Finally, conclusion describes theories of interpretation and legislature.
