Dispute over the property boundary: boundary marker and survey

If the exact boundary course is disputed or boundary markers have disappeared, an official boundary determination by the surveying office or a publicly appointed surveying engineer creates clarity. Unilateral assumptions about the boundary often lead to costly disputes, professional clarification is better.

Your chances of getting your money back

The binding boundary course is determined by the official survey on the basis of the real-estate cadastre. Disappeared boundary markers can be restored (re-marked) as part of a boundary determination.
In the case of an unclear boundary, you can apply for a boundary determination. If the boundary can no longer be determined, there are statutory rules on boundary confusion by which the boundary is fixed (§ 920 BGB).

Frequently asked questions

How is the exact boundary course determined?

Through an official boundary determination based on the real-estate cadastre, carried out by the surveying office or a publicly appointed surveying engineer. The result is binding; disappeared boundary markers can be restored in the process.

What if boundary markers have disappeared?

They can be newly set (re-marked) as part of a boundary determination. If the course can no longer be ascertained, statutory rules on boundary confusion apply, by which the boundary is fixed, for example according to the state of possession (§ 920 BGB).

Who bears the costs of the survey?

In principle the person who commissions the boundary determination. In the case of an amicable initiation, the neighbors can split the costs. The exact allocation depends on the individual case and any agreement.
