BUPi explained for property buyers

If you are looking at rural land in the north or centre of Portugal, you will hear the word BUPi sooner or later. Since 2026 it is no longer a technicality: for rustic and mixed plots, it has become part of the sale itself.

What BUPi is

BUPi (Balcão Único do Prédio, or Single Property Desk) is the Portuguese state’s platform for identifying rural plots in municipalities that have never had a full land cadastre.

The georeferenced graphic representation, known as RGG, records the plot’s proposed mapped location and configuration and links it to the available tax and registry information. An RGG may be validated with a geometry reservation; it is not an absolute guarantee of title or undisputed boundaries.

Why it matters to you as a buyer

The 2026 amendments broadened the property-identification requirements in Article 19 of Law 78/2017. For the transactions and properties covered, the RGG number is generally required, with provisions for an official database check, plots already on the Cadastral Map and statutory exceptions. In practical terms:

• Check identification before completion. Establish whether the plot requires an RGG or has the appropriate cadastral identification, and whether any exception applies.
• Compare the outline with the evidence. Check it against the title, the other records and the land; confirm whether it has a geometry reservation.
• Overlaps need investigation. An RGG can remain validated with a reservation where a private boundary conflict is unresolved. That is not automatically a bar to registration, but the risk needs to be understood and dealt with in the contract.

The temporary free regime ended on 30 September 2026. Municipal or intermunicipal assistance and registration procedures may now attract the applicable public charges, while wholly online identification remains free under current official information. Private professional fees are separate. The contract should state who pays each cost.

What to check

• Is the property in a BUPi municipality? If the area already has a cadastre, other rules and documents apply.
• Has every plot been mapped? A single property for sale is often made up of several separate plots, each with its own record. All of them need checking.
• Does the outline match the ground? Walk the boundaries and compare them with the RGG. Outlines drawn from memory, or by someone who has not visited the land in years, are common.
• Are there overlaps or pending disputes? Ask whether any neighbour has contested the boundaries.
• Does the RGG match the other records? Compare the mapped area with the Land Registry and the tax record.

If the plot is not on BUPi yet

If mapping is required, arrange it before completion using suitable evidence and a qualified technician where necessary. A site visit may be important for the service being commissioned, but is not a universal statutory requirement for every RGG.

The promissory contract should say who arranges it, who pays, and what happens if the outline turns out different from what you were told, or if a neighbour objects.

BUPi is where law and land meet

BUPi links legal and geometric information. At MGPS International we coordinate the legal review and the technical work through the professionals qualified for each procedure.

We can:

• check whether each plot is mapped, and whether the outline matches the land and the other records;
• flag overlaps and boundary issues before you commit;
• carry out the mapping ourselves and the related registration steps;
• write all of this into a promissory contract that protects you.
