BUPi and Rural Properties: New Rules on Georeferencing, Boundaries and Registration in 2026
The legal framework governing the Balcão Único do Prédio (BUPi), which regulates the georeferencing of rural properties, has once again been amended.
Regulatory Decree no. 8/2026 of 21 September updates the rules governing the Simplified Cadastral Information System and introduces new provisions relevant to the identification, georeferencing and registration of rural and mixed-use properties. The Decree entered into force on 22 September 2026.
The principal changes include new requirements concerning Georeferenced Graphic Representation (RGG), clearer rules concerning adjoining properties and public-domain land, an administrative conciliation procedure for boundary disputes and new time limits applicable to registration proceedings.
What is a Georeferenced Graphic Representation?
An RGG – Representação Gráfica Georreferenciada, or Georeferenced Graphic Representation, digitally identifies the location and boundaries of a property using geographical coordinates.
In practical terms, it corresponds to the representation of the land as a polygon on the BUPi platform.
The georeferencing of rural properties is particularly important in municipalities where no cadastral survey yet exists, as it enables the physical reality of the property to be linked to the information recorded in the tax register and land registry.
The new rules further reinforce the importance of this procedure.
1. The georeferencing of rural properties becomes more important in consolidation
One of the principal amendments concerns the consolidation of rural properties.
In municipalities without an existing cadastral survey, completion of the RGG procedure becomes a prerequisite not only for the special procedures for registration and justification of title concerning rural and mixed-use properties, but also for the special procedure for the consolidation of rural properties.
Accordingly, where several rural properties are to be consolidated into a single registered property, their correct geographical identification assumes increased importance.
2. Time limits are established for validation of the RGG
The reform also seeks to make the procedure more predictable.
Once submitted through BUPi, the RGG is sent to an authorised technician for validation, with a time limit of 20 working days established for that purpose.
Where corrections or additional information are required, the interested party is likewise given a period within which to make the necessary amendments.
This is relevant because the absence of a valid RGG may prevent or delay other procedures relating to the property.
3. When must adjoining property owners intervene?
Property boundaries are one of the main sources of difficulty when identifying rural land.
The new regime clarifies the circumstances in which a declaration from the owners of adjoining properties is required.
Where the polygons of adjoining properties capable of being georeferenced are already represented on BUPi and there is no conflict concerning the shared boundaries, validation may proceed on the basis of that information.
Where an adjoining property cannot be georeferenced through BUPi, a declaration of acceptance from the respective owner may be required.
The amendment seeks to avoid unnecessary formalities where the available geographical information is already sufficient to confirm that the boundaries are compatible.
4. What happens when two properties overlap?
This is where one of the most interesting new features of the regime arises.
Where polygons overlap and the issue cannot be resolved automatically, an administrative conciliation procedure may be initiated through BUPi.
The procedure may be commenced by the authorities of their own motion or at the request of any interested party.
Its purpose is to allow property owners to seek agreement on the delimitation of their respective properties before resorting to judicial proceedings.
5. How does the conciliation procedure work?
During the conciliation procedure, the parties may amend their respective graphic representations or seek to reach an agreement concerning the boundaries.
Where agreement is reached, it is formalised and the relevant RGGs may be amended accordingly.
If the dispute cannot be resolved at the initial stage, a conciliation hearing may be held.
The new regime also allows such a hearing to take place by electronic means.
6. What if no agreement is reached?
The administrative procedure does not remove the right to resort to the traditional mechanisms for resolving disputes.
Where overlaps remain following completion of the conciliation procedure, the parties may, depending on the circumstances, resort to a Justice of the Peace Court, arbitration or the other judicial remedies available by law.
The conciliation procedure therefore operates as an additional mechanism intended to resolve boundary disputes in a simpler manner.
7. Greater coordination with public-domain property
Regulatory Decree no. 8/2026 also introduces clearer rules for situations in which an RGG overlaps land or assets forming part of the public domain.
The competent public authorities are given a greater role in making relevant geographical information available through BUPi and keeping that information up to date.
Where a conflict is identified between the representation of a private property and the boundaries of public-domain assets, the interested party may be required to correct the representation.
Correctly identifying such situations is particularly important for properties adjoining public roads, paths, watercourses or other areas subject to specific legal regimes.
8. New time limits in land registration procedures
The amendments also cover the special land registration procedures.
Specific time limits now apply to the preliminary review of documentation by the land registry service and to the correction of certain deficiencies by the interested parties.
The aim is to make the procedure more predictable and to reduce situations in which the regularisation of a property remains pending indefinitely without a decision.
Georeferencing is not merely a technical issue
Although BUPi has a strong cartographic component, the delimitation of a property produces very concrete legal consequences.
Discrepancies concerning area, location or boundaries may affect:
- a sale and purchase transaction;
- an inheritance or partition;
- the consolidation or division of land;
- a planning or licensing procedure;
- construction works;
- bank financing;
- a dispute between neighbouring property owners.
An RGG should therefore not be considered in isolation from the property tax register, the land registry and the documents establishing title to the property.
Particular relevance for properties in the Algarve
In the Algarve, rural and mixed-use properties are frequently found with old descriptions, imprecise boundary references or discrepancies between the area existing on the ground and the area recorded in the tax and land registries.
These issues may remain without practical consequences for many years and only emerge when the owner seeks to sell, build on, divide, consolidate or otherwise regularise the property.
Before carrying out a transaction involving land, it is therefore important to verify whether the physical reality of the property corresponds to its documentary and registration status.
Frequently Asked Questions
Does BUPi replace the land registry?
No. Georeferencing identifies the property geographically, while the land registry records and publicises its legal status.
Is the consent of neighbouring owners always required?
No. The need for a declaration from adjoining owners depends on the specific circumstances and on the geographical information already available through BUPi.
What happens if two RGGs overlap?
An administrative conciliation procedure may be initiated in an attempt to resolve the dispute concerning the property boundaries.
Can I sell a property if there are discrepancies in its recorded area?
It depends on the nature and extent of the discrepancy. In many cases, prior regularisation is advisable in order to avoid difficulties at the time of the deed or at a later stage.
Should the BUPi information be checked before buying land?
Yes. Particularly in the case of rural and mixed-use properties, the documentary review should be accompanied by confirmation of the effective location, area and boundaries of the property.
