The first registration in the Land Book is the procedure by which a building located on the territory of the country is assigned a cadastral number and is registered in the Land Book, thus proving the existence of the real or personal right registered. Types of real estate for which the first registration in the Land Book is required:

• Apartments, commercial, administrative, technical spaces, etc – called individual units – represent real estate located in a codomain (construction that includes both exclusive parts – individual units and common parts)
• Land located in town (with or without construction) or out of town
• New constructions – valid for buildings built on the basis of a building permit for which there is a receipt for the completion of the works and a certificate attesting the building.

The operation of first registration in CF is performed only once for each building, the subsequent transaction does not involve a “new cadastre” is sufficient to tabulate the property right in the Land Book.

This type of operation is necessary for situations when the technical data of the building (part I of the Land Book) undergoes changes:

• Modifications of the shape and surface of the building – in the situation when the surface or cadastral limit of a building must be modified (as a result of an overlap or a dispute, etc.)
• Changes of the out-of-town / in-town regime – in the situation when an out-of-town land is transferred within the built-up area of the locality based on a decision of the local council.
• Demolition / demolition of constructions – in the situation when a construction is demolished, based on a demolition authorization and the reception process at the end of the works, the cadastral update is performed for the deregistration from the CF of the demolished constructions.
• Extensions or superstructures of the constructions – if a construction is modified by an authorization issued by the City Hall, then after the completion and reception of the works, an update documentation is drawn up.
• Changes in the postal address – when a building receives a postal number or it is changed, the cadastral updating documentation is made so that these changes are registered in the cadastral records and the Land Book.
• Interior subdivision changes – when authorized interior subdivision works are performed for an individual building or unit in a codomain.
• Approval of the internal surveys of a construction – for the situations when the constructions were registered in the CF without the approval of the internal surveys. In this situation, based on an update documentation, the internal surveys of the constructions are approved by OCPI.
• Correction of material errors – if the cadastral documentation contains material errors they are corrected by a technical data update documentation.

Dismantling is the operation by which a building registered in the Land Book is divided into several buildings, each building resulting from the dismantling will receive a new cadastral number.

• Land dismantling – a land type property registered in the CF can be dismantled into two or more lands through the cadastral dismantling operation. The dismemberment in two lots can be done directly, for dismemberments in more than two lots it is necessary for the owner to obtain a Town Planning Certificate for dismemberment.
• Dismantling of individual units (UI) – buildings of individual unit type (spaces inside a building: apartments, commercial spaces, administrative spaces, etc. that are registered in the CF) can be dismantled into two or more units provided that the resulting units are separated by fixed partitions and there are separate entrances.
• Dismantling the building / apartment – is the operation by which a building registered in the CF is dismantled to create individual units (apartments, storage rooms, indoor parking lots, commercial spaces, etc.). Through this operation the building becomes a codomain, it will contain units that will be owned exclusively and common parts. The apartment is the last cadastral operation carried out within a residential project.

Unification of plots is the operation by which two or more buildings are unified to form a new building.

• Unification of plots – two or more land-type buildings registered in the CF can be annexed to create a new building. The cadastral attachment operation can be performed directly in the situation where two plots of land are attached; in the situation when more than two plots of land are attached, it is necessary for the owner to obtain a Town Planning Certificate in order to join.
• Unification of individual units (UI): two or more buildings of individual unit type (apartments, commercial spaces, administrative spaces) inside a building can be attached to form a new space. The internal partitioning cannot be modified by the cadastral attachment operation.

The technical approvals represent planimetric and altimetric situation plans taken into account by the Offices of Cadastre and Real Estate Advertising. These approvals are requested by the Mayors through the town planning certificates issued. We distinguish:

• Technical approval for the start of works – it is issued by OCPI and is required for any work of photogrammetry, cartography, cadastre, geodesy, etc. for works exceeding 100ha or for any PUG and PUZ work regardless of the surface.
• Technical approval for the construction authorization project – the technical approval for the elaboration of the construction authorization project can be obtained for any land type building registered in the Land Book and which does not have overlaps in the cadastral database.
• Technical approval for the detailed urban plan – the technical approval for the elaboration of the detailed urban plan can be obtained for any land type building registered in the Land Book and which does not present overlaps in the cadastral database. For this approval it is necessary to have a Town Planning Certificate.
• Technical approval for the zonal urban plan – the technical approval for the elaboration of the zonal urban plan can be obtained on a building or for several buildings registered or not registered in the Land Book. For this approval it is necessary to have an Urbanism Certificate.
• Technical approval for the General Urban Plan – the technical approval for the elaboration of the general urban plan is elaborated for an entire administrative territory.
