Buying off-plan in Portugal: paying for construction you cannot see

Portugal has no automatic statutory backstop for off-plan deposits. What should evidence each construction stage before you release the next payment.

An off-plan purchase in Portugal asks a buyer to pay for a building in instalments while it is still being built, and Portugal is the only one of its six nearest comparison markets with no automatic statutory scheme protecting those instalments. France imposes a guarantee of completion. Spain requires every advance payment to be individually guaranteed. Germany regulates the progress-payment schedule itself. Portugal leaves all of it to the contract, which means a buyer's protection is whatever was negotiated into the CPCV and nothing more. The practical consequence sits in how payments are triggered: a tranche released against a calendar date pays for progress that may not exist, and a tranche released against a verified construction stage does not. The new build snagging inspection guide covers the inspection at handover. This one covers everything before it.

What actually protects your money before the building exists?

Nothing automatic. Portugal imposes no mandatory buyer-fund protection scheme for off-plan purchases, so every safeguard has to be written into the contract.

Set against the markets most foreign buyers come from, the gap is stark and it is structural rather than accidental.

France requires a garantie financière d'achèvement, a guarantee of completion, on off-plan sales. Spain requires every advance payment to be individually guaranteed by a bank or insurer. Germany regulates the instalment schedule itself through the MaBV, tying payments to defined construction stages by law. The Netherlands and the United Kingdom reach near-universal coverage through market and lender-driven warranty schemes, SWK and Woningborg in the Dutch case, NHBC Buildmark in the British one.

Portugal has no equivalent. A garantia bancária in the buyer's favour and a lawyer or notary escrow account both exist as instruments and both work, but neither is automatic and neither appears unless somebody negotiates it into the promissory contract. The default position is that staged payments go straight to the developer's working capital.

That is the fact the rest of this article follows from. It is also why the comparison guide, mandatory diagnostics in Portugal against Europe, and the buyer protection guide both keep arriving at the same conclusion from different directions: Portuguese buyer protection is opt-in, and the opting-in happens before signature or not at all.

Where this article stops. Drafting the contract, registering the CPCV for eficácia real, and the law governing deposits are transaction questions rather than building questions. RealOS covers that side. What follows is the part that turns on the building itself.


Why do calendar-based payment milestones cost buyers money?

A payment triggered by a date releases money whether or not the construction stage it was meant to pay for has actually been reached.

This is the single most common structural weakness in Portuguese off-plan contracts, and it is easy to miss because a schedule of dates looks like precision.

A contract that says the second tranche falls due on 31 March creates an obligation that arrives on 31 March. If the frame is three months behind, the buyer still pays, and the money leaves before the thing it was paying for exists. Every subsequent stage inherits that position, and by the time the gap becomes visible the buyer has funded a building that is materially less complete than the payment schedule implies.

A contract that says the second tranche falls due on completion of the structural shell, evidenced by inspection creates a different obligation. The trigger is a state of the world rather than a date, and verifying the state of the world is a task somebody can perform.

The distinction matters more in Portugal than in the markets with statutory schemes, because there is no fund standing behind the buyer if the developer runs out of money halfway. Overpaying relative to progress is not a cash-flow inconvenience. It is unsecured exposure.


What should evidence each stage before you release a tranche?

Each milestone should be tied to a verifiable construction stage and confirmed by site inspection or an architect's certificate before payment leaves.

The sequence below is the standard shape of a Portuguese off-plan payment ladder. What matters is the right-hand column.

Reservation. A small holding payment. Nothing to verify on site yet, but this is the point to confirm the developer's IMPIC registration and the alvará de construção, the construction permit, before any money moves at all.

CPCV tranche, commonly around 10%. Contract signature. Verify that the permit covers what is being sold, and that the project matches what the marketing describes.

Foundations. Verifiable on site. This is the first stage where an inspection produces a yes or no rather than an opinion.

Structural shell. Verifiable, and the most expensive stage to get wrong, because everything after it is built on top and concealment begins here.

Roof and weathertight envelope. Verifiable, and the stage that determines whether the building is protected from water during the internal works that follow.

Internal works and the habitation licence. Two separate things. The internal works are verifiable by inspection. The licença de utilização is a document, and confirming it was actually issued matters more now than it once did, because Decreto-Lei n.º 10/2024, de 8 de janeiro removed the licence as a gate on the deed. The State no longer forces a developer to produce it at completion. Our guide to checking the habitation licence covers how.

Balance at the escritura. The final payment, and the last moment with any leverage.

Two contractual items belong alongside the ladder.

The finishes schedule. The Mapa de Acabamentos or memória descritiva specifies materials and finishes. Developers commonly include an "equivalent materials" clause allowing substitution, nominally for supply reasons, and it is regularly used to downgrade. Specifying brand and model, or a defined quality standard, and capping substitution to equivalent or superior subject to written approval, is standard practice among Portuguese conveyancing lawyers. Treat it as practice rather than as settled case law, because the enforceability of specific wording has not been tested in a way that can be cited.

Snagging retention. Holding back 5% to 10% for roughly twelve months after the deed, to cover defects that surface in use, is contractually permissible in Portugal. It is negotiated, not statutory, and it has to be drafted in with clear release conditions.


What happens if the developer company fails mid-build?

Portuguese developers routinely build through single-purpose companies, so a CPCV can end up being a claim against an entity with no assets.

The vehicle is usually a thinly capitalised sociedade por quotas set up for one project. It is an ordinary and legal structure, and it is also the reason a buyer's position can evaporate rather than degrade.

Two routes survive that.

Direct action against the builder, under Article 1225.º of the Código Civil. Where the works concern buildings intended by their nature to be long-lasting, the empreiteiro answers for defects arising from the ground or the construction for five years from delivery, and a third-party acquirer can pursue the builder directly rather than being confined to the developer who sold. Notification runs within one year of discovery and the action within one year of that notification. This is the main structural escape from an insolvent project company.

A parent or affiliate guarantee. A fiança or garantia autónoma binding a solvent parent is enforceable in Portugal where it is properly documented in writing. It is worth exactly as much as the guarantor's own solvency, so verifying that the parent is not itself a shell is part of the exercise.

Neither route is a substitute for not overpaying against progress in the first place, which is the point of the previous section.

Do not merge the two warranty regimes, because they answer differently. Decreto-Lei n.º 84/2021, de 18 de outubro, in force since 1 January 2022, is the consumer regime where a professional sells to a consumer: ten years on structural elements, five on everything else, with a non-conformity appearing inside the period presumed to have existed at delivery, which reverses the burden onto the seller. Article 1225.º is the separate direct-against-the-builder route with its own five-year window and its own deadlines. The new-build warranties guide sets out both, and the guide to a developer ignoring your snagging list covers what a properly communicated defect notice does to the clock.


What changes at completion, and what does not?

The building becomes yours and the liability for anything unresolved comes with it, which is why the verification happens before the balance is paid.

Three things are worth separating at this point.

The licence question is now the buyer's. Since 1 January 2024 no municipal authority checks the building against its approved project before a deed completes. From 1 October 2026, under Decreto-Lei n.º 108/2026, de 29 de maio, whose commencement was deferred to that date by Decreto-Lei n.º 155-B/2026, de 31 de julho, the document titling the transfer must mention the status of the urbanistic title. That adds a declaration. Nobody inspects the building as a result of it.

Enforcement exposure travels with the property. Where works were carried out outside what was permitted, the RJUE contraordenação regime reaches from €498.80 to €99,759.58 for individuals and up to €249,398.95 for companies, and the obligation attaches to whoever owns the property when the authority acts.

A dispute is slow unless the contract says otherwise. Ordinary civil proceedings over construction defects commonly run for years at first instance before any appeal. Arbitration through a Ministry-supported centre runs materially faster, typically a few months. An arbitration clause is something to put in the CPCV rather than something to look for afterwards, and it should name the centre with competence over construction disputes rather than assuming one.

An InspectOS snagging inspection sends an engineer registered with the Ordem dos Engenheiros to the property before acceptance, and can be run at construction stages as well as at handover. The deliverable is a dated record with photographs, locations and severity grading, signed with the engineer's cédula identified, delivered within 48 hours. Against a payment ladder where each tranche is unsecured, verifying the stage before the money leaves is the cheap half of the transaction.

By way of contrast on the other side of the market, INE, Censos 2021 records 35.8% of Portuguese buildings as needing repair, split 21.8% light, 9.4% medium and 4.6% deep. A new build starts outside that distribution. Whether it stays outside depends on what was actually built, which is the thing nobody checks by default.

Frequently Asked Questions

Is my deposit protected if I buy off-plan in Portugal?

Not automatically. Portugal imposes no mandatory scheme guaranteeing off-plan buyer payments, unlike France, Spain and Germany. Protection exists as instruments, a bank guarantee in your favour or a lawyer or notary escrow account, but each has to be negotiated into the promissory contract before signature. Without that, staged payments go to the developer's working capital.

Should off-plan payments be tied to dates or to construction stages?

To construction stages, each evidenced by site inspection or an architect's certificate before the payment is released. A tranche triggered by a calendar date falls due whether or not the work it was meant to pay for has been done, which means the buyer funds progress that may not exist and carries that gap forward through every later stage.

Can I claim against the builder if the developer company is dissolved?

Article 1225.º of the Código Civil allows a third-party acquirer to pursue the empreiteiro directly for defects arising from the ground or the construction, for five years from delivery, with notification within one year of discovery and the action within one year of that. That is separate from the consumer regime under Decreto-Lei n.º 84/2021 and the two should not be merged, because their periods and deadlines differ.

What is the "equivalent materials" clause and should I accept it?

It is a clause in the finishes schedule allowing the developer to substitute specified materials. Some flexibility is reasonable on a multi-year build. The usual lawyer-grade approach is to name brand and model, or a defined quality standard, for the items that matter, and to cap substitution to equivalent or superior subject to your written approval, rather than leaving the word "equivalent" undefined.

Does the 1 October 2026 change affect an off-plan purchase?

It adds a declaration to the document titling the transfer about the status of the urbanistic title. It creates no inspection and no verification of the building, and the notary performs no physical check either before or after that date. Confirming the licença de utilização was actually issued remains the buyer's job, and has been since municipal verification was removed from the deed on 1 January 2024.


Conclusion

Off-plan buying in Portugal is not riskier than elsewhere because Portuguese developers are worse. It is riskier because the safety net other European markets legislate into existence is here left to negotiation, and most buyers do not know there is anything to negotiate.

Two decisions carry most of the weight, and both are made before signature. Tie every payment to a construction stage rather than a date. Have each stage verified before the money leaves.

Everything else in this article, the guarantee instrument, the finishes specification, the retention, the arbitration clause, is a refinement on those two. A buyer who gets the payment triggers right is never badly exposed, because the money and the building stay in step.
