How do you identify the boundary line

How can you find "your" landmark?

Can't find the boundary stone?

If you want to build your own home on a piece of land close to the border or if you want to put up a fence between your and the neighboring property, you need to know exactly where the property line is.

Determining this on site is not that easy. Because the parcels into which our land is divided by the real estate cadastre are marked by boundary stones, which are very often not (no longer) really visible. Why? Mainly for two reasons:

  • In urban residential areas, in contrast to agricultural and forestry areas, boundary stones are usually not set high, but flush with the ground
  • Especially when boundary points were defined years or decades ago, nature has often long since overgrown the stone markings

This is how you can find “your” landmark

To locate a boundary stone, you can contact the land surveying and land registry office responsible for you. Here you can usually get exact coordinates for your boundary stone. All you have to do is know your land number - thanks to the fact that precise property maps (e.g. also in 3D view) are now often made available to citizens by some of the local land registry offices, this can usually be found out with a few clicks.

An official border information is usually only issued if the coordinates are already recorded in the real estate cadastre according to highly precise and reliable criteria, especially for border points that are not marked - i.e. not marked with an actual boundary stone.

In the case of marked border points, coordinate information that is not as highly accurate can be issued in individual cases. If you cannot find out clearly on the online portal of your responsible land surveying office whether the property line in question contains marked or unmarked boundary points, you should seek personal advice from the responsible regional directorate. Often it is also possible to acquire geodata online - without going to the office.

For the publication of the official boundary stone coordinates, a fee is usually due according to the fee guidelines of the respective surveying and cadastral administration.

With the coordinates - mostly they are now published in UTM format - you can locate the boundary stone with the help of GPS aids on site.
