The document outlines Bulgaria's digital cadastre and property register system, established by the Cadastre and Property Register Act of 2001, managed by the Geodesy, Cartography and Cadastre Agency (GCCA) with 28 regional offices. It details the integration of a digital information system for maintaining accurate records of immovable properties, ownership rights, and transactions, involving various user groups including government institutions and private companies. The system enhances operational efficiency through automated data exchange and offers users online access to a range of cadastral services.

1. Digital cadaster in Bulgaria.
Information system of cadaster
and property register

Sofia, 2014

2. Digital cadastre and property register in Bulgaria - 1
 Cadastre and property register act (CPRA) has been establish in 2001 and
it arranges new principles for the organization, funding, creation,
administration and use of the cadastre and the property register;
 Geodesy, cartography and cadastre agency (GCCA) is an executive
agency established with main functions pursuant to the Cadastre and property
register act;
 The Agency is a legal entity, having its seat in Sofia and operating through its
28 regional units – Geodesy, Cartography and Cadastre Offices (GCCO),
located in the administrative centres of the regions;
 The cadastre is created, maintained and stored by the Agency for geodesy,
cartography and cadastre;
 The property register is kept and stored by the Registry Agency;

3. Digital cadastre and property register in Bulgaria - 3
 The cadastre and the property register are created, maintained up-to-date
and stored in digital form in Integrated information systems for cadastre
property register (IISCPR) ;
 IISCPR deliver the bilateral connection between cadastre and the property
register, based on the identifier of immovable properties;
 Cadastre and properties register are integrated and exchange information;
 Users of digital cadastre and property register (CPR) data:
 Cadastre and Property registration Agencies employees;
 Specialists participating in CPR business processes (notaries, geodetic and
surveying companies;
 Government and municipal institutions;
 Private service companies (banks, property brokers, utilities, etc.);
 End users (citizens, legal entities, media, etc.).

4. Contents of cadastre map and cadastral registers
 The cadastre data are mapped out on a cadastre map and recorded in
cadastral registers;
 The cadastre aggregates data about:
 Location, boundaries and extent of immovable property within the territory of the
Republic of Bulgaria;
 Right of ownership on immovable properties;
 Other real rights over immovable properties;
 State borders;
 Boundaries of administrative-territorial units;
 Boundaries of territories belonging to settlements;
 Boundaries of territories of identical durable land use;
 Data about the right of ownership and other real rights over immovable
properties in the cadastre shall be received from the property register.

5. Contents of the property register
 The property register comprises the lots of the immovable properties.
 In the property register are recorded:
 the acts recognizing or conveying right of ownership;
 the acts establishing, conveying, modifying and terminating other real right
over immovable properties;
 interdictions and mortgages over the latter;
 other legal actions, circumstances and legal facts for which recordation is
envisaged by law.
 The basic data about the immovable properties in the property
register shall be received from the cadastre.

6. Territorial administrative units – 28 districts
District boundaries
District administrative center
Capital city

7. Territorial administrative units – 264 municipality
District boundaries
Municipality boundaries

8. Territorial units – settlement lands
 Municipalities are subdivided
into settlement lands;
 Urbanized territory and
surrounding agricultural and
forest territories belonging to
the settlement are located
within its boundaries;
 Every settlement has a unique
code (EKATTE) from the
Unified classifier of
administrative-territorial units;
 The immovable properties
receive unique identifier
formed within the boundaries
of a settlement;

9. Data sources for creating cadastral map and
cadastral registers
Data from previous cadastral,
regulation or structural plans
Data for the owners and holders of
other real rights gathered from the
registers to the maps and plans,
the registers of the municipal and
regional administration;
Data gathered through geodetic,
photogrametric and other
measuring and calculations
Data from digital map of the
restored ownership of agricultural
and forest land The data that correspond by
contents and precision the
requirements determined by
the CPR Act are combined
for creating digital cadastral
map and cadastral registers

10. Immovable properties, objects in the cadastre
 Landed property is the basic unit of the cadastre,
it is a part of the surface of the earth, including
durably covered with water, defined by boundaries
compliant with the right of ownership. The landed
properties is fully cover up the territory of the
country, defined by the state borders, without
overlapping each other.
 Building, including also rough construction
(building or structure which surrounding walls and
roof have been made)
 Self-contained object (SCO) in a building or in
a facility of the technical infrastructure - part of
the building or facility that has a self-dependent
function and building with exposed walls. SCO
can be an apartment, office, studio, garage, store
 Each landed property, building or self-contained
object shall be attributed an identifier, a unique
number by which the immovable property is
singularly identified within the territory of the
country.

11. The unique identifier of an land property in cadastre
 The territory of a settlement land is divided into cadastral regions
 A cadastral region is limited by boundaries of settlement lands, boundaries of cities and boundaries of existing
linear objects or topographic forms on the land - roads, railways, rivers, gulches and other
 Every cadastral region received a unique number within the boundary of the settlement land
 A cadastral region contains land properties that receives a unique number within the boundary of the
corresponding cadastral region.
 The unique identifier of an land property consists the EKATTE code of the settlement, the number of the
corresponding cadastral region and the sequent number within the boundary of the cadastral region, divided by
“dot”.
Boundary of a settlement land
with EKATTE code 06286
Cadastral region N76
within the boundary
of a settlement land
Land property N20
in the boundary of
a cadastral regions
Landed property identifier
06286.76.20

12. • Buildings receive sequent numbers within the land property they belongs. For creating the building
identifier this number is added at the end of the land property identifier
• Self-contained object (SCO) receive sequent numbers within the building they belongs. For
creating the SCO identifier this number is added at the end of the building identifier
The unique identifier of a Building and Self-
contained object in cadastre
Building N1 in parcel 06286.501.230
has identifier 06286.501.230.1
501
SCO N1 in building 06286.501.230.1
has identifier 06286.501.230.1.1
501

 Implementation of INSPIRE data specifications for as developed by the
Thematic Working Group
 Harmonization of spatial data sets and implementation of INSPIRE data
specifications for the Thematic Working Group:
