The complex of norms surrounding “owner-possessor relationships” (§§ 985-1003 BGB) as well as claims for “negatory injunctive relief and removal” (§ 1004 BGB) have been the subject of vibrant academic discussion as well as important German Supreme Court decisions. The revised edition of this trusted legal commentary undertakes a comprehensive and critical assessment of the new material that has arisen in these areas of law. A host of new legal decisions were integrated into the commentary on § 1006 BGB (“Presumption of Ownership in Favor of the Possessor”). The discussion has also been expanded concerning § 1007 BGB, an aspect of law that continues to present great difficulties.
