When two people each hold one half of an apartment building, the selection of a manager can fail because neither side has a majority. Section 836 ABGB provides for common property that the majority of votes selects the manager. If that majority is absent, the judge decides on the selection.
The judicial route is therefore tied to a specific management issue. It does not replace a review of the ownership structure and does not turn ordinary co-ownership into condominium ownership. The land register, agreements, management need and previous attempts to reach agreement should be documented separately. The article on selling a co-ownership share addresses the economic side of such a share.
