The Missing Step in the Portuguese Home-Buying Process
Search "how to buy a house in Portugal" and you will find hundreds of guides. They all say the same thing: check the land registry certificate, request the property tax record, confirm the occupancy license, demand the energy certificate. Property documentation is exhaustively covered. And rightly so, those documents are essential.
But there is a step missing from virtually all of those guides. A step so basic that it seems impossible nobody mentions it: verifying who built the property or who you are hiring to do work on it.
The standard due diligence pattern in Portugal
Real estate due diligence in Portugal is very well documented when it comes to the property itself. The certidao permanente (land registry certificate) to confirm ownership and encumbrances. The caderneta predial (property tax record) to validate the fiscal value. The occupancy license to ensure the authorized use. The mandatory energy certificate from the listing stage.
For those applying for a mortgage, the bank conducts its own property valuation. It assesses the market value, checks for obvious irregularities, and confirms the financing is compatible with the asset. If you have a lawyer, they review the contracts and verify the registration status.
All of this is focused on one question: "Is this property in order?"
The question that almost nobody asks is: "Is the person or company selling me this, or that I am hiring to work on it, in order?"
The gap is real
This is not a perception. It is a verifiable fact. Home-buying guides published by the largest real estate agencies, personal finance portals, and legal blogs, none of them include "verify the builder" on the checklist. Due diligence on the contracting party, the developer, the contractor, simply is not part of the standard process.
The partial exception is off-plan purchases. In this case, some professionals and guides recommend checking the developer's financial stability, the track record of previous projects, and whether there are court proceedings. Data collected by PortugalProperty.com in the Algarve region between 2023 and 2024 suggests that buyers who use independent legal representation have 82% fewer issues with real estate transactions. But even in this scenario, verification is recommended as an extra, not as a mandatory step in the process.
Literally every person I ask says the same thing: they never verified anything about the contractor or builder they hired. They requested quotes, compared prices, looked at photos of previous work, asked for word-of-mouth references. But nobody went to CITIUS to search for court proceedings. Nobody verified the license on IMPIC. Nobody checked debtor lists.
Why this happens
There are several reasons for this gap:
- The tools exist but nobody knows about them - CITIUS is public, the IMPIC portal is public, the Tax Authority debtor list is public. But they are 7 different databases, each with its own format, search logic, and terminology. They were not designed for the average citizen
- The word-of-mouth culture - in Portugal, hiring contractors still works largely through recommendations. "My neighbor used this builder and it went well" is considered sufficient verification. But the neighbor did not check court proceedings
- Legislation made it easier, not harder - Law 41/2015 simplified access to the construction industry. Licenses became indefinitely valid. Annual IMPIC controls exist, but they are not pre-contractual verification mechanisms for consumers
- No tradition of counterparty verification - in Portugal, checking someone's court history before handing them money is not normal. It would almost be considered excessive distrust. Yet checking a property's registry certificate before buying it is considered basic prudence. It is a cultural inconsistency
What happens when you do not verify
The examples are numerous and increasingly frequent:
Palmela, 2024-2025: 114 families paid deposits for houses that were never delivered. EUR 27 million lost. The developer had warning signs that a 5-minute search would have revealed.
The Rendisphera/Lumobras pattern: companies that go insolvent, and the same directors reappear in other companies with new tax numbers. The so-called "corporate carousel" is a documented practice in Portugal's construction sector. Without checking director history, it is impossible to detect this pattern.
The daily cases: just browse Reddit, consumer forums, or Facebook groups about construction in Portugal. Every week there are reports of contractors who disappear with deposits, who abandon work midway, who fail to meet deadlines or budgets. And the vast majority of victims say the same thing: "I did not check anything beforehand."
The irony of warranties
Portugal has a reasonable legal framework for consumer protection in construction. The Civil Code, in Article 1225, establishes a 5-year warranty for property defects. Decree-Law 84/2021 extends the warranty to 10 years for structural defects. These are generous periods compared to many European countries.
But there is an irony: these warranties are reactive. They work after the problem has occurred. After you have already paid, after you have already handed over money, after you are already in the middle of a problematic construction project. And if the company goes insolvent, the warranty becomes virtually unenforceable. Ordinary creditors in insolvency proceedings recover a minimal fraction of their credits, when they recover anything at all.
Prevention, verifying before hiring, is infinitely more effective than trying to enforce warranties afterwards. But prevention requires information, and until now that information was scattered across multiple databases inaccessible to most people.
The tools exist, but nobody uses them
All the information needed to verify a builder in Portugal is public and free:
- CITIUS - court proceedings, insolvencies, PER (Special Revitalization Process)
- IMPIC - construction license status, class and categories
- MJ Publications - official publications of corporate acts and insolvency proceedings
- Tax Authority debtor list - companies with fiscal debts above a certain threshold
- Social Security debtor list - companies in contributory default
- Portal BASE - awarded public contracts
- Commercial registry - corporate information, directors, share capital
The problem is not the lack of information. It is the dispersion. There are 7 different databases, each with its own interface, search logic, and technical terminology. For an ordinary citizen who wants to hire a contractor for a renovation, navigating all these sources is simply impractical.
The missing step
The process of buying a house in Portugal, or hiring for construction work, should include a simple and obvious step: verify the builder. In the same way you request a land registry certificate to check whether the house has mortgages, you should request a report on the company to check whether it has insolvency proceedings, tax debts, or a history of problematic directors.
ObraXRAY was created exactly for this. It cross-references the 7 Portuguese public databases, automates the search, and delivers a complete risk report with a score, identified and classified court proceedings, license status, and director analysis. All in minutes, all in plain language.
It does not replace a lawyer. It does not replace common sense. But it adds a layer of information that, until now, simply did not exist in an accessible way for the average consumer.
Important note: every case is different. Legislation and procedures vary, and no verification system replaces professional legal advice. Always consult a lawyer before making decisions involving significant amounts.
