Revision

All components of the official cadastral survey are subject to the revison obligation. A distinction is made between ongoing and periodic updating.

• Ongoing revisions includes the updating of property changes as well as updating  that is necessary as a result of structural changes.
• Objects that change for natural reasons, such as forest edges, stream and river courses, rues and the like, are periodically revised.

Property changes

Each landowner has the opportunity to change a plot of land by separating a part of it, land swap or unification of parcels. For this purpose, he reports to the responsible land surveyor or the municipality. An order for mutation is then formulated together. The municipality building inspector then examines the project from the point of view of building law. After a positive result of the examination, the surveyor draws up the deed of mutation. The entry in the land register is made on the basis of a contract (or an application, if all the plots concerned have the same owner). The mutation becomes legally binding only after the entry in the land register. If, in the course of a mutation, easements, e.g. a right of way, are also to be registered, this entry must be specially noted in the contract or land register application. Further details on the  procedure of a boundary mutation can be found here.

Updating of buildings and reconstruction of boundary signs

The surveyor reponsibeble for revision is obligated by a contract with the state to ensure that the work of the official cadastral survey is permanently traced and remains in perfect and up-to-date condition. In the case of structural changes, the surveyor is informed by the municipalities about the objects to be revised. The revision is carried out without a direct order from the building owner in accordance with the legal mandate.

Cost bearing

The principle applies that each party responsible for the tracking must bear the costs. Thus, in the case of boundary changes, the owner is liable for costs, and in the case of building updates, the builder is liable for costs. In the case of periodic updates or changes to the country's network of fixed points, however, the state bears the costs.

The billing of costs for mutations is done according to the Fee Ordinance 33 of the Cantonal Surveying Offices of Switzerland. Further information can be found in the following documents:
