BUPi in Portugal: Registering Rural Land in Portugal

BUPi in Portugal: Registering Rural Land in 2026

If you own or want to buy rural land in Portugal, you will come across BUPi. It is the government system for mapping and registering rural and mixed properties, and since 2026 it matters for every sale: a sale of rural or mixed land now requires a georeferenced map of the plot. At the same time, the free registration period ended on 30 September 2026.

This guide explains what BUPi is, what changed in 2026, what it costs now, how registration works and what it means for buyers and sellers.

What is BUPi?

BUPi stands for Balcão Único do Prédio, the “single property desk”. Large parts of Portugal, especially in the north and centre, have no complete land cadastre: many rural plots are registered for tax purposes, but nobody has officially mapped their exact boundaries. BUPi closes that gap. Owners draw their plot on a map, the result is validated by a qualified technician, and the plot can then be registered at the land registry.

The result is the RGG (Representação Gráfica Georreferenciada), a georeferenced map of the property linked to its tax record. BUPi covers rural (rústico) and mixed (misto) properties in municipalities without a geometric cadastre. Urban properties such as apartments and houses on urban plots are not affected.

Unlike the UK, where HM Land Registry holds title plans for registered land, or the US, where boundaries are usually set by a survey at closing, Portugal is still in the middle of mapping much of its rural land. By September 2026, about 46 % of the area of the municipalities without a cadastre had been identified.

What changed in 2026

Decree-Law 87/2026 of 15 April 2026 brought the most important changes so far:

• RGG mandatory for sales: documents transferring ownership of rural or mixed property must include the RGG. In practice, you can no longer buy or sell such land without it.
• RGG mandatory for subsidies: applications for financial support involving rural or mixed property, including EU funds, must include the RGG.
• End of the free period: identification and registration were free for plots up to 50 hectares until 30 September 2026.
• New annexation procedure: neighbouring rural plots can now be merged through a simplified procedure at the BUPi desk.

What does BUPi cost now?

Since 1 October 2026:

Drawing the map yourself online remains possible. Private surveyors charge their own fees.

How registration works

1. Check your municipality: BUPi only applies where there is no geometric cadastre. You can check on the official BUPi website.
2. Gather documents: ID, Portuguese tax number (NIF) and the tax record (Caderneta Predial) with the matrix number of the plot; if available, your title deed or land registry certificate (Certidão Permanente).
3. Draw the boundaries: online (with Portuguese digital authentication), with the BUPi app using your phone’s GPS while walking the boundary, or at a BUPi desk at the town hall with a qualified technician.
4. Validation: the technician checks the map against neighbouring plots and documents.
5. Registration: with the validated RGG, the property is registered or updated at the land registry. If there is no title document, a justification procedure is needed.

If you live abroad, a representative with a power of attorney, such as your lawyer, can do this for you.

What BUPi means for buyers

If you are buying rural land or a farmhouse (quinta) on a mixed property, BUPi is now part of your due diligence:

• Ask early whether an RGG exists. Without it, the deed cannot be signed. If the seller still has to create one, this costs time, and with boundary disputes or missing documents it can take months.
• Compare areas. The area in the tax record, the land registry and the RGG often differ. The RGG shows what you are really buying.
• Put it in the contract. Make the RGG and the registration the seller’s obligation in the promissory contract (CPCV), with a deadline and a condition that protects your deposit.
• Check neighbours and access. The validation process can reveal disputed boundaries or missing rights of way.

What BUPi means for owners

If you own rural land that is not yet identified, register it before you plan to sell, pass it on or apply for subsidies. The cost is modest, but the process takes time, and unresolved boundaries can block a sale.
