10. The amelioration certificate of a land property shall be made by the Service and one copy
thereof shall be in the possession of the relevant territorial office of the Service, but the other
– with the landowner or legal possessor.
11. The Service shall clarify and enter information into the amelioration cadastre, on the basis
of the documentation regarding the construction, writing off inventory of the amelioration
systems and data of the register of the State cadastre of immovable property in compliance
with regulatory enactments regarding exchange of the amelioration cadastre information.
12. The accuracy of the amelioration cadastre information and of the changes made thereto
shall be certified by the signature of an official, specifying the date of the entry made
(including in the electronic database, where possible).
13. The Service shall establish and introduce an electronic amelioration cadastre data base,
developing the structure of the text and graphic part, contents and data exchange procedures,
as well as shall ensure the usage (development) of a unified software of the register, observing
the requirements specified in regulatory enactments regarding the State information systems.
14. The electronic amelioration cadastre database shall be maintained by the Service.
Documents upon the basis of which the amelioration cadastre is established and maintained
shall be stored permanently on paper and/or electronically.
III. Inventory of Amelioration Systems
15. Amelioration systems shall be inventoried in accordance with Section 15 of the
Amelioration Law in order to ensure renewal of the data base of the amelioration cadastre and
State administration of the amelioration systems on and which is in a certain property or legal
