When in 1993 the law concerning private foundations was enacted, the main idea that was to be implemented was the creation of an "ownerless" structure, which by means of dedication of assets to a certain purpose assigned by the founder, was designed to serve the aforesaid indelibly, determinedly and better than in case of a continued attachment to the fate of the founder and his legal successors or a corporation, respectively. Accordingly, a separation of the legal spheres of the founder and the foundation takes place, by which the founder usually divests himself of a substantial part of his/her assets. Frequently, a private foundation is seen as a not insubstantial reduction of the liability deposit towards creditors and mandatory heirs. Nevertheless, the founder can maintain essential, owner-like influences on the endowment fund of the foundation. These legal powers are based in majority on the so called founder's rights.This thesis will explain under which conditions the founder's creditors will still be enabled to satisfy their claims by means of seizure upon the endowment fund of the foundation. Subsequently, the founder's rights in general as well as those which allow the founder to pursue owner-like interests are examined. On this basis, the possibility of attachability of these rights by the founder's creditors, mainly in respect to paragraph 3Abs3PSG is argued. Since the PSG does not include creditor's protection regulations, other general regulations, which can be used as a creditor's protection, are debated.
