Your chances of getting your money back

An obligation to enclose and the cost allocation follow from state neighbor law and municipal statutes. A shared facility standing on the boundary is maintained jointly by both neighbors (§§ 921, 922 BGB).

For a shared boundary facility, the neighbors as a rule split the upkeep costs in half. A written agreement on type, height, and costs prevents disputes.
