A. At the time of dissolution of redevelopment association due to revocation of authorization, the provisions governing incorporated associations in the Civil Act shall apply mutatis mutandis, except as otherwise provided in the Act on the Maintenance and Improvement of Urban Areas and Dwelling Conditions for Residents (hereinafter “Act”). However, the Civil Act only allows a liquidator to file a petition for bankruptcy (Article 79 of the Civil Act), and does not require a legal entity to pay obligations to its members, who are separate legal entities from the legal entity (Article 79 of the Civil Act). In addition, if the redevelopment association can seek a share of the remaining obligations to its members, (i) if the redevelopment association imposes liability on its members due to the act of the association, even if it fails to select its members as a per se, it goes against the principle of self-responsibility.

If partners waive a project in advance because there is no economic feasibility, etc. in the rearrangement project, if they give up the project in advance, they are more unfavorable than the case where construction is completed by leaving the project in progress.
