Updating/ Mutations
All components of the official cadastral survey are subject to updating. A distinction is made between ongoing and periodic updating.
- Ongoing updating includes the updating of property changes and updating that is necessary as a result of structural changes.
- Objects that change for natural reasons, such as forest edges, stream and river courses, gullies and the like, are updated periodically.
Property changes
Every landowner has the option of changing a plot of land by separating off a section of land, exchanging land or merging plots. For this purpose, they must contact the responsible land surveyor or the municipality. An order for mutation is then jointly formulated. The municipal building inspector then examines the project in terms of building law. If the result of the examination is positive, the surveyor draws up the mutation certificate. The entry in the Land Register Division is made on the basis of a contract (or application if all the properties concerned have the same owner). The mutation only becomes legally binding once it has been entered in the Land Register Division. If easements, e.g. a right of way, are also to be entered in the course of a mutation, this entry must be specifically noted in the contract or land register application. Further details on the process of a boundary mutation can be found here.
Updating buildings and reconstructing boundary signs
The surveyor is obliged by a work contract with the state to ensure that the official cadastral survey is permanently updated and remains in perfect and current condition. In the event of structural changes, the surveyor is informed by the municipalities about the objects to be updated. Updating is carried out without a direct order from the client in accordance with the legal mandate.
Assumption of costs
The principle applies that each party responsible for a survey must bear the costs. For example, the owner is liable for the costs of boundary mutations and the building owner for building updates. In the case of periodic updates or changes to the country's fixed point network, however, the state bears the costs.
The costs for changes are invoiced in accordance with the fee schedule 33 of the cantonal surveying offices of Switzerland. Further information can be found in the following documents:
