Author considers that Apartment Ownership System consists of two parts. They are ownership and righe of partnership (right of membership, right of participation). In 1983, there was a revision of condominium law, in which the second part became a major issue of the law and the firstpart became a minor part, Then, in next revision made in 2002, it became conclusive in relation to Rebuilding regulation. As a result, definition of ownership in the context of condominium law became different from what of civil law. As of 2002, ownership in relation to condominium law was imposed restrictions on time as well as on space.
