The revised volume on the law of lien on moveable objects and rights takes into consideration the current legal developments in this field. It is essential to have a reliable commentary to turn to that leads to practical solutions in cases that involve the lien on moveable objects. This is particularly important due to the fact that the law of lien on moveable objects does not provide the intended security functions as envisioned by the lawmakers and because it has been nearly replaced by other security measures, such as assignment and transfer of ownership by way of security. In addition, the commentary on the Ship Register Act (Schiffsregistergesetz) offers a compact yet precise presentation of the significant provisions of the Ship Property Act (Schiffssachenrecht).
