You can identify the limits of your property online by logging in with your Citizen Card (requires a card reader and plugin) or with your Digital Mobile Key (CMD) and respective PIN codes.

BUPi Desks

If you need the support of an authorised technician or do not have electronic authentication, you can identify your properties at a BUPi Desk. Check the list of BUPi Desks in the municipality where your property is located.

Property identification

To identify the location and limits of your properties, you can visit the BUPi Desk in the municipality where your property is located.

Property registration

You can schedule your land registration appointment using this link.

Land Registry Office

After submitting the georeferencing request for your properties through BUPi, you must go to the Land Registry Office, which will already have all the information about the location and limits of your property, in order to complete the registration.

You can also submit the request online.

If your municipality has a cadastral system, visit the website of the Directorate-General for the Territory for more information.

Administrative Conciliation

If geometric overlaps persist upon the expiry of the rectification period, the interested parties are summoned to a formal conciliation hearing.

If no agreement is reached during the hearing, the RGGs of the conflicting properties remain validated with a geometry reservation in respect of the unresolved overlaps. In such circumstances, interested parties may seek redress through the Justices of the Peace court having territorial jurisdiction, statutory administrative arbitration, or any other legally admissible judicial remedies.

Partial boundary agreements may be legally executed.

In such cases, the RGGs are rectified in respect of the boundary segments covered by the agreement, while the unresolved overlaps remain subject to the existing geometry reservation.

If the rectification successfully eliminates the geometric overlap, the RGG is updated in accordance with the revised boundary delimitation.

Where the owners reach a binding agreement, such agreement is formally recorded within the procedural file, and the corresponding RGGs are amended accordingly.

The affected property owners are formally notified of the conflicting RGGs and are afforded the opportunity to rectify their property boundaries or reach an agreement regarding their common boundary lines.

Where the procedure is initiated ex officio: Interested parties have a statutory period of 20 working days to arrange the necessary boundary corrections with a qualified technician;

Where the procedure is initiated upon application by an interested party: The remaining interested parties are notified to rectify their respective RGGs or reach a boundary agreement within the same statutory window of 20 working days.

An application for administrative conciliation must be submitted in person by lodging a formal written request at a local BUPi municipal desk (Balcão BUPi) or before a certified Cadastral Technician (TCP). Upon receipt of the application and gathering of the necessary documentation, the conciliator creates the formal procedure dossier within the BUPi digital platform.

The conciliation procedure may be initiated:

  • Ex officio by decision of the Technical Coordination Centre;
  • Directly by the appointed administrative conciliator; or
  • Upon formal application by any interested party.

Administrative conciliation may be conducted where geometric overlaps exist between RGGs of adjoining land parcels that cannot be resolved through the automated boundary adjustment mechanisms provided for on the BUPi platform under applicable law.

Administrative conciliation is a statutory dispute resolution procedure designed to assist adjoining landowners in reaching an amicable agreement where geometric overlaps exist regarding their common property boundaries.

The objective of the procedure is to establish mutually agreed property boundaries and to rectify the conflicting Georeferenced Graphical Representations (RGG).

Public Consultation

Adjoining properties that have not been identified during the public consultation are subject to the procedure for identifying and recognising rural or mixed-use properties with no known owner, provided for in Decree-Law No. 15/2019 of 21 January, as amended.

The application of this procedure does not mean that the property is automatically considered to have no known owner. Any such recognition depends on compliance with the requirements established by law.

This distinction arises from Article 7-C of Law No. 65/2019, which establishes additional conditions for initiating the recognition procedure.

Yes. After submission, a confirmation message will be displayed.

The objection receipt automatically opens in a new window and is also available in the list of documents associated with the objection.

No. All documents must be attached before submitting the objection.

Once you select “Submit Objection”, it is no longer possible to add or modify documents through that form.

Therefore, before submitting, make sure you have attached all the necessary documents.

Yes. You can attach several documents by selecting the corresponding document type and uploading the relevant file.

If you select the “Other” category, you must specify the type of document you wish to attach.

To submit an objection online, you must attach at least one document under the “Objection” category.

The attached documents must correspond to the items identified in the objection form and provide supporting evidence for the objection submitted.

You can submit an objection online or in person.

  • Online: on the BUPi Public Consultation Map, select the RGG you wish to contest and choose the “Online Objection” option. You will be redirected to the portal, where you must authenticate to begin the process.
  • In person: you can visit a BUPi Desk in the municipality where the property covered by the public consultation is located.

Objections must be submitted within the deadline specified in the relevant public consultation notice.

What tools are available on the map?

The map provides several tools to facilitate access to the information, including:

  • Address search;
  • Zooming in and out of the map;
  • Access to the list of RGG processes included in the selected public consultation.

These features allow users to locate properties and consult the available geographical information.

Yes. On the map, you can select the relevant public consultation and view the Georeferenced Graphic Representation (RGG) processes included in it.

When you select an RGG, a window appears displaying detailed information about the corresponding process.

The information can be accessed through the BUPi Public Consultation Map, available on the BUPi GeoPortal.

To access it, select the option “Access the BUPi Public Consultation Map”, which allows you to view the geographical information relating to the properties covered by the consultation.

It means allowing the Georeferenced Graphic Representations (RGG) of rural and mixed-use properties to be reviewed and their boundaries to be confirmed or contested, where applicable, with a view to validation without a geometry reservation and subsequent integration into the Cadastral Map.

The public consultation provides an opportunity for property owners and other interested parties to verify whether property boundaries are accurately represented and to submit objections if they identify any inaccuracies.

Participation is particularly important because, once the information has been integrated into the Cadastral Map, the recorded location, configuration and area of the properties benefit from a legal presumption that they correspond to the physical reality, without prejudice to evidence to the contrary.

The deadline for submitting objections is 60 working days, calculated from the date on which the official notices are posted and published on the local authority's official website.

The start and end dates of the objection submission period are announced in the notice for each public consultation.

The Aljão Public Consultation covers the Aljão Integrated Landscape Management Area (AIGP), in the municipality of Gouveia, including areas within the civil parishes of Cativelos, Ribamondego, Arcozelo da Serra and the Union of the Civil Parishes of Rio Torto and Lagarinhos.

The public consultation began on 20 May 2026. The 60-working-day period for submitting objections has ended, and the procedure is now at the stage of assessment of the objections submitted by the Administrative Committee, as provided for by law.

Current status: Objection assessment stage.

A public consultation is a procedure through which Georeferenced Graphic Representations (RGG) of rural and mixed-use properties located within the area concerned, which have no overlaps but are subject to a geometry reservation, are made available for public review and potential validation, with a view to their integration into the Cadastral Map.

The Aljão Public Consultation covers the Aljão Integrated Landscape Management Area (AIGP), in the municipality of Gouveia, inThe “Beira Atlântico” Public Consultation covers Georeferenced Graphic Representations (RGG) with no overlaps and validated with a geometry reservation in the municipalities of Ílhavo, Mira, Santa Maria da Feira and Vagos, including all their civil parishes.

The public consultation begins on 21 October 2026. The period for submitting objections lasts 60 working days, until 18 January 2027.

Following this period, the Administrative Committee will assess the objections submitted, within a period of 90 working days.

Current status: Objection submission period.

The public consultation includes Georeferenced Graphic Representations (RGG) with no overlaps and validated with a geometry reservation, located within the area covered by the consultation.

RGG validated without a geometry reservation are integrated into the Cadastral Map through interoperability and therefore do not need to undergo public consultation.

RGG with overlapping areas are not included in the public consultation. These situations may be resolved through the administrative conciliation procedure.

A public consultation comprises two stages:

  • Submission of objections: during a period of 60 working days, property owners and other interested parties may consult the available RGG and submit objections if they identify inaccuracies in the information presented.
  • Assessment of objections: once the submission period has ended, the Administrative Committee has 90 working days to assess the objections received.

The public consultation is only considered concluded after the objection assessment stage.

Once the public consultation has been concluded, Georeferenced Graphic Representations (RGG) that meet the legal requirements may be integrated into the Cadastral Map.

Following this integration, the information concerning the location, configuration and area of the properties benefits from a legal presumption that it corresponds to the physical reality, without prejudice to evidence to the contrary.

From that point onwards, any corrections can no longer be made as part of the public consultation. Instead, they are subject to a cadastral maintenance procedure provided for under the Legal Framework for the Property Cadastre (Decree-Law No. 72/2023), requiring the mandatory involvement of a cadastral surveyor. This procedure may require additional technical documentation and entails costs.

Costs

To identify properties

If you identify your properties at a BUPi Desk, with the support of a qualified technician, the cost per RGG is:

• €15 per RGG, up to your 9th RGG;

• €10 per RGG, from your 10th RGG onwards.

Identification carried out entirely online, on the BUPi platform, is free of charge.


To register property ownership

Please check the costs of land registration with the Land Registry Office.

No. RGG processes started before 1 October 2026 are not included in the count.

The cost of each RGG carried out at a BUPi Desk depends on how many RGGs you have already done.

RGGs are counted by the interested party’s tax number (NIF). If someone else starts the process on your behalf, the RGG counts towards your NIF, not theirs.


All RGGs started on or after 1 October 2026 count, including those done online. It doesn’t matter where the land is or which BUPi Desk the process started at.

Documentation

To carry out the identification or registration, you must have the Tax Authority Land Certificate for your property. In some cases, the BUPi Desk or the Land Registry Office may be able to access this information, but it is always preferable to have the document with you.

Check the Documentation page to see all the required documents.

Online

To identify the location and limits of your property online, you must log in using your Citizen Card and PIN codes. Alternatively, you can use your Digital Mobile Key (CMD), with access to the associated phone.

You must also have your Tax Authority Land Certificate, which contains the matrix numbers of the properties you wish to georeference.

If you already have a GPS file with your property's coordinates, you can upload it to the BUPi platform. If not, you can identify your property directly on the map.

BUPi Desk

When visiting a BUPi Desk, you should bring your Citizen Card and the Tax Authority Land Certificate showing the matrix numbers of the properties to georeference. Alternatively, you can provide the matrix number and your NIF so that the authorised technician can retrieve the certificate via the Tax Portal.

You should be able to locate your property on the map and, if possible, bring a GPS survey of the property’s limits. If you're unable to identify your property, our technicians at the BUPi Desk can assist you.

For more information, visit the Documentation page.

If you own a property but do not have any document proving it belongs to you, you can initiate a justification of rights (through a court process, special registration procedure, or notarial deed of justification) to demonstrate that you live on or make use of the property under conditions that allow it to be registered in your name.

For more information, contact the nearest Land Registry Office.

Documents you must bring

Check here which documents are required based on your specific situation.

Documents that prove ownership
You must provide one of the following documents to prove that the property belongs to you:

  • Deed of purchase and sale or donation
  • Declaration of Heirs
  • Court decision granting you the right of ownership
  • Law or other legal document granting you that right

For more information, see the Documentation page.

Identification/Location

  • Inform the promoter about the discrepancy in area.
  • If the promoter confirms that the property has the identified area and limits, the RGG is submitted. The interested party must then be informed that they need to update the area in the land registry, in accordance with the Land Registry Code.

Simplified land registration is a declarative process. Its main value lies in allowing the identification of property owners and the location of their properties. It is therefore natural that, during this gradual process, existing conflicts regarding property boundaries may come to light.

However, the simplified registration system contains information with varying levels of positional accuracy — from freely drawn polygons to, in many cases, traditional topographic surveys. There are also mechanisms in place to reduce the number of conflicts, including artificial intelligence algorithms and improved tools within the BUPi platform that help ensure compliance with current legislation on boundary adjustments and adjoining properties.

To avoid overlapping polygons, before starting to draw your property, check the following:

Whether the polygon overlaps with public domain areas (road network, hydrographic network, etc.). In such cases, please note that the authorised technician will reject the RGG.

Whether your property overlaps with or borders properties that have not yet been georeferenced. In these cases, you can still register your property, and the RGG will be validated with a reservation.

By following these steps, you help ensure that the RGG process will be smooth and efficient.

To correct or update the area of a rural property located in a municipality without a cadastral system and already covered by the Simplified Cadastral Information System, you must begin by initiating the RGG process using the correct area of the property.

Once the RGG process is complete, you should go to a Land Registry Office and request the correction/update of the area, stating that the area in the RGG should be considered for registration purposes, as it is the accurate one. This correction/update will follow the rules set out in the Land Registry Code, along with the provisions of Article 16 of Law No. 78/2017, of 17 August.

You do not need to go to the Portuguese Tax and Customs Authority to request the area update in the matrix, as it will be processed automatically between the services.

Defining the location and limits of your property ensures that those limits can be restored, even if physical markers disappear. This provides effective protection of your property.

You can locate your properties in several ways:

  • Drawing the property polygon directly on the digital map available on the BUPi platform
  • Using the BUPi App, which allows you to physically walk the land and mark it on a map
  • Drawing the polygon using Google Earth Pro
  • Requesting support from an authorised technician at a BUPi Desk

If you use the BUPi App or Google Earth Pro, don’t forget to download the map/file so you can upload it later to the BUPi platform.
Accepted file formats are: KML, GPX, TopoJSON, and Shapefile with a *.zip extension.

  • The taxpayer listed in the matrix (the person named in the Tax Authority Land Certificate)
  • The registered holder (the person with a registered ownership or usufruct right)
  • An interested party who is entitled to request registration acts at the Land Registry Office (for example, the buyer and seller in a public deed of purchase and sale; the donor and the donee in a public deed of donation; those legally required to promote the registration, such as notaries, solicitors, or lawyers; the surviving spouse or heir in relation to assets forming part of an undivided estate; any co-owner)
    An interested party who holds powers of representation, granted through a power of attorney

For more information, see the Step-by-step page.

To register a rural property in the matrix, located in a municipality without a cadastral system and already covered by BUPi, you must first go to a BUPi Desk and fill out a declaration to initiate the process for registering an unlisted property and creating a provisional RGG.

Next, you must go to the Tax Office with the request to register the unlisted property in the matrix, along with a declaration of acceptance from at least one adjoining property owner.

Once the matrix article is assigned, you must return to the BUPi Desk to finalise the RGG and proceed with registration at the Land Registry Office.

Ownership legitimacy

If the promoter is acting as a representative, they must present a power of attorney granting them authority to carry out the RGG, issued by the person who is legally allowed to submit it.

This can be a simple power of attorney, requiring only the grantor’s signature and identification document reference. The simplified power of attorney template available on the BUPi platform grants representation powers exclusively for the RGG procedure.

If the grantor cannot write or sign, the required RGG documents must be signed on their behalf by another person at their request. In such cases, the signature must be certified by a registry office, notary, or another authorised entity or professional (such as lawyers or solicitors).

You can consult the available templates below: Modelo Tipo Procuração Simplificada

In addition to providing the corporate taxpayer number (NIPC), the following documents are required:

  • If the entity is subject to commercial registration: the access code to the permanent commercial certificate
  • If the entity is not subject to commercial registration: its statutes, the document appointing the governing bodies, and the statement of acceptance of office

The RGG is submitted by the promoting spouse, using the ownership details as listed in the matrix. The ownership status will be addressed later during the registration process.

The RGG is submitted by the promoting co-owner, and all other co-owners listed in the Tax Authority Land Certificate must also be identified.

The RGG can be initiated by any heir, who must present the following documents:

  • The Tax Authority Land Certificate of the property and one of the following:
  • Proof of the Tax Identification Number (NIF) of the undivided estate
  • Declaration of Heirs
  • Stamp Duty payment document
  • Will with the death officially recorded

If the area stated in the Tax Authority Land Certificate is incorrect, you should begin by carrying out the RGG. In this case, the correct area of the rural property will be automatically communicated to the Portuguese Tax and Customs Authority.

If another piece of information in the Tax Authority Land Certificate is incorrect — for example, a bordering property — you must first go to the Portuguese Tax and Customs Authority before proceeding with the RGG.

In cases where the person concerned is neither the taxpayer listed in the matrix nor the registered holder, they must generally fill out a declaration of ownership legitimacy.

Although this declaration does not cover all possible legitimacy situations when the person is not listed in the matrix or as the registered owner (since Article 36 of the Land Registry Code allows registration by any person with a legitimate interest), it does cover most cases — particularly when the person has a document to register at the Land Registry Office or intends to initiate a justification of rights (at the Land Registry Office or a Notary Office, including through adverse possession).

This declaration also helps the authorised technician assess ownership legitimacy.

Municipalities with and without a cadastral system

To ensure that a property is legally yours, you must register it at the Land Registry Office.

Properties that are not identified in BUPi and not registered in the Land Registry may be subject to a procedure to recognise them as ownerless. In such cases, they will be provisionally registered in the name of the State.

There is no difference in the land registration procedure itself — the Land Registry rules are the same throughout the country.

For georeferencing in municipalities without a Land Cadastre, you must present the Georeferenced Graphic Representation (RGG); in municipalities with a Land Cadastre, you must present the Geometric Configuration of the Property (CGP).

Yes. If your property is located in a municipality without a Land Cadastre, you must identify its limits in BUPi.

If the municipality where your land is located already has a Land Cadastre, you do not need to carry out the identification (Georeferenced Graphic Representation — RGG). It is sufficient to present the Geometric Configuration of the Property (CGP).

You can check whether the CGP already exists using the viewer provided by the Directorate-General for the Territory.

If the municipality where your land is located already has a Land Cadastre, you can register the property at the Land Registry Office.

Platform and App

You have several options:

BUPi App — You can use the BUPi App to physically walk the land and locate it that way.

BUPi platform — The BUPi platform includes a feature that can help you deduce the location of your property.

BUPi Desk — At the BUPi Desks, authorised technicians are available to help you locate your property. You can also use the deduction feature, which relies on available data — such as neighbouring properties — to help determine where your land may be located.

No. To use the BUPi platform, you only need to log in using your Digital Mobile Key or, if you prefer, your Citizen Card (Portuguese national ID card). In the latter case, you will need a card reader and the corresponding plugin installed. This authentication ensures the security of your data.

No. The platform is a convenient way to complete the process entirely online, but you can also go to a BUPi Desk in person.

Select your municipality to find the nearest BUPi Desk.

No. The App offers that possibility — meaning, if you’re unable to locate your land on the map, you can go to the site and use GPS to identify it. However, you can also locate your property directly on the map within the App, without needing to travel to it physically.

To install the BUPi App, you only need a mobile phone or tablet. For the App to function properly, the device must be equipped with GPS and have internet access.

Registration

If your land is already properly registered at the Land Registry Office in your name, you should still identify it in BUPi by submitting an RGG. This ensures that there is no doubt about the location and limits of your property.

The aim is for all plots of land across the country to be identified either in BUPi or in the Land Cadastre, so that land can be better managed and forest fires can be prevented.

To find out whether your properties are registered at the Land Registry Office, you can:

  • Check through a Tax Authority Land Certificate
  • Go to a Land Registry Office and provide your matrix article number, parish, and municipality

Your ownership rights and other property rights are only fully guaranteed when they are registered at the Land Registry Office. Only land registration offers legal certainty about who owns the property.

Registration at the Land Registry Office is almost always mandatory, particularly in the following situations:

  • When you purchase land
  • When you create a usufruct or easement over the land
  • When you justify ownership of land (for example, through adverse possession)
  • When you lease land for more than six years

To register your rural or mixed-use property, you must first identify it in BUPi — unless your municipality already has a Land Cadastre.

Check this page to see whether your municipality has a Land Cadastre or if identification in BUPi is required.

After you complete your Georeferenced Graphic Representation (RGG) in BUPi, the land registration will include a note stating that an RGG exists.
