A boundary examination compares documents, coordinate information and actual land use. A fence, cadastral line and historical boundary may differ, so the source of each line must be identified.

Subject of examination

  • EGRN information and documents on the plot's formation
  • Actual fences and objects associated with use
  • Measurements and graphical materials in a common coordinate reference system

Sample questions for the expert

  • How do the documented and actual boundaries relate?
  • What are the area and configuration of the identified discrepancy?
  • Which source documents allow the boundary's position to be checked?
  • Are the measurements sufficient to answer the questions asked?

The final questions are formulated according to the objects and circumstances of the particular task.

What to prepare

  • Current extracts and coordinate information
  • Title and land surveying documents
  • Plans, diagrams and previous boundary survey materials
  • Information about fences, the dispute and access to the object

How the examination is conducted

Coordinate sources and the accuracy of source data are checked before comparison. On-site measurements and graphical constructions are determined by the task and available documents.

Scope and limitations

An expert comparison does not replace changes to EGRN or determine ownership rights. Land value and geobotanical condition are not automatically included in a boundary examination.

What the deliverable records

A verifiable comparison, discrepancy calculations and diagrams are prepared, identifying the origin of each line and the limitations of the data.

Cost and terms

from RUB 50,000. The exact price depends on the number of plots, volume of documents, need for a site visit and number of questions.

How to read a boundary comparison and the areas of discrepancies

A diagram may show a line based on EGRN information, the actual fence and a boundary from an earlier document at the same time. To check the result, each line needs its own designation and source reference. If one line covers another on the plan, this does not mean that the source data matches completely.

A comparison table helps move from an image to verifiable quantities. It can link the plot or outline designation, documented area, measured coordinates and calculated area of discrepancy. A separate explanation identifies the source points and data used to construct each outline and the transformations required to display them together.

What to clarify about the source materials

  • Are coordinates available, or is there only a graphical plan without sufficient georeferencing?
  • What are the date, scale and purpose of the archival diagram, and has the original been preserved?
  • Which objects associated with actual use were measured, and when was the inspection carried out?
  • What changes to fences, buildings and vehicle routes occurred between the dates being considered?

A diagram from an electronic map or a screenshot cannot be treated as equivalent to on-site measurement results without verification. A small visual discrepancy requires assessment of the accuracy and suitability of the source information. The question of which line should legally determine a party's right is separated from the technical description of the location, area and sources of the discrepancy. This allows the graphical appendix to be used together with calculations, rather than in place of their justification.
