Recently, several legal problems has been rising in the management of the common apartments. For example, some managers of the apartments are appointed by the apartment construction companies and they work for the companies, not for residents. The residents want to manage their apartments themselves, but they don`t know much about information of that. And they don`t have much experience about the management, so they have some damages. There is a decision of Korean Supreme Court about the apartment management, and that decision held that the debt of the manager who was appointed by the construction company was not the debt of residents of the apartment. I think that this decision is right because the residents didn`t have any opportunity about controlling that debt. This thesis is the study on the several legal problems of the apartment management. And this study is about the provisions of Korean Civil Law and other several laws about the apartment management rules. The contents of these provisions are not sufficient for protecting residents of common apartments and some are apt to be misused by the construction about that. The apartment management rules are made by the decision of the residents, but the procedures of making those are also able to be misused by the construction companies or management companies. So the procedures of protecting residents are needed. And also the residents of common apartments are needed to act actively for their apartments management.
