Run property due diligence in Portugal without surprises after closing in 2026

Portugal commercial property has two costs non-Portuguese buyers rarely model correctly upfront: IMT at 6.5% on commercial property (calculated on the higher of transaction value or VPT - the fiscal reference value) plus 0.8% Imposto de Selo on top. Both are due at the notary on closing day.

Portugal uses a civil law system; all property transfers require a notary (Notário). The notary drafts the escritura (deed of sale) and the property is then registered in the Conservatória do Registo Predial (land registry). These are two separate steps after signing.

There are two separate registries for Portuguese property: the Conservatória do Registo Predial (land registry) and the Caderneta Predial (fiscal registration at the tax authority, AT). Both must be consistent and current before any transaction.

The licença de utilização (use license from the Câmara Municipal) is mandatory for all commercial buildings. Without it, the building has no legal authority to operate commercially. Missing use licenses are common in Portugal, especially in older or renovated buildings.

Set up an Ellty data room before diligence opens. Load land registry extracts, caderneta, building permits, use licenses, and lease files before advisors arrive. Each advisor gets a scoped link from day one.

Where Portugal property deals go wrong

Not every check carries the same weight. The table below sorts risks by deal impact - dealbreakers first, then what moves the price, then basic hygiene - so your Portuguese advogado and technical advisor know what to clear first.

Portugal CRE checklist

The table ranked risks by severity. This is the full list to work through, grouped by area.

Land registry and title

• Pull the certidão de teor from the Conservatória do Registo Predial on day one; this is the definitive land registry extract
• Pull the caderneta predial from AT (tax authority) simultaneously; confirm both documents describe the same property and the same owner
• Any discrepancy between the Conservatória and the AT caderneta signals unregistered works, fiscal irregularity, or title issues
• Check the article number (artigo matricial) in the caderneta against the description (descrição) in the land registry; they should correspond
• For rural properties or older industrial sites: confirm whether there are multiple parcels and that all parcels are correctly registered
• Confirm the NIPC (tax identification number) of the selling entity matches on all documents

Licença de utilização

• Request the licença de utilização for the building from the Câmara Municipal (local council)
• Confirm the authorized use on the license matches the current commercial use of the property
• For buildings constructed before 1951 in Lisbon and 1944 in Porto: some older buildings are exempt from the requirement under legacy provisions, but confirm the exemption with the local council
• For buildings that have been renovated: confirm a new or updated licença de utilização was issued post-renovation
• Missing use license: budget 3-6 months for regularization via the local Câmara; it requires as-built drawings, technical reports, and council inspection

Encumbrances and ónus

• Confirm from the certidão de teor that all encumbrances (ónus) are listed: mortgages (hipotecas), liens, rights of use, and easements
• Confirm any existing mortgage has a bank commitment to discharge on closing; the notary will require this
• For properties with multiple encumbrances: your advogado should prepare a discharge sequence plan as part of the CPCV negotiation
• Check for any pending court proceedings (penhoras - judicial attachments) registered on the land title

Planning violations - desconformidades

• Compare the licença de construção and as-built plans against the current physical state of the building
• For any additional floor, mezzanine, extension, or change from the licensed use: confirm whether municipal licensing was obtained
• Unauthorized works (obras sem licença) are common in Portuguese commercial buildings and create enforcement risk for the new owner
• The Câmara Municipal can require demolition or regularization of unauthorized structures
• Regularization (licenciamento extraordinário) is possible in some cases but is time-consuming and not guaranteed

IMT, IS, and VPT gap

• Confirm the VPT (Valor Patrimonial Tributável) from the caderneta predial; this is the AT's fiscal reference value
• Calculate IMT on the higher of the transaction price or the VPT: for commercial (prédios urbanos não habitacionais), the IMT rate is 6.5%
• Calculate IS (Imposto de Selo) at 0.8% on the same base; it's payable in addition to IMT
• For transactions where IVA (VAT) at 23% applies (new commercial buildings or opted transactions): confirm whether IMT is waived; IS still applies
• Request IMT guia (payment slip) from AT through your advogado; it must be paid before the notary appointment

IMI arrears

• Confirm the AT has no outstanding IMI (annual property tax) balance against the property via an AT debt certificate
• The notary requires confirmation of no outstanding IMI before completing the escritura
• Outstanding IMI arrears are charged against the property itself; they transfer to the buyer if not cleared
• Confirm the VPT on the caderneta is reasonable relative to market value; significantly undervalued VPT may attract AT challenge

Give each advisor a scoped link in Ellty. Your advogado sees the Conservatória and caderneta. Technical consultants see building plans and licença. Environmental advisors see Phase I reports. No overlap.

Leases and tenant rights

• Collect all lease contracts (contratos de arrendamento) and confirm compliance with the NRAU (New Urban Leasing Regime)
• Check for older pre-NRAU leases: commercial leases signed before the NRAU reforms (2012-2019) may have indefinite renewal rights or protected status
• Confirm Imposto de Selo was correctly paid on each lease at signing; unpaid IS creates AT liability
• Cross-reference the rent roll against 12 months of actual receipts; confirm any outstanding rent arrears
• For vacant commercial properties: confirm the licença de utilização covers the authorized use class and that no enforcement proceedings are active

Energy certificate - CDE

• Confirm the CDE (Certificado de Desempenho Energético) is registered in the SCE (Sistema de Certificação Energética) database
• The CDE is mandatory for any commercial property transaction or new tenancy agreement; missing CDE blocks the notary
• Check the energy class (A to G); Portuguese commercial buildings commonly rate C to F
• For older buildings with poor energy ratings: model the energy upgrade investment required to comply with upcoming EU minimum energy performance standards

Environmental - mines and industrial

• Commission Phase I ESA for any site near former mining areas: Panasqueira (tungsten), São Domingos (copper), Aljustrel (pyrite), and Rio Tinto watershed
• For Setúbal Industrial Zone (Baía do Tejo) and Sines petrochemical complex: contamination risk is significant; Phase I is mandatory and Phase II likely
• Search the APA SIRER (contaminated sites register) for the property address and surrounding area
• For logistics and industrial assets in the Lisbon Logistics Corridor (Azambuja, Santarém): background contamination check is standard

Load all Phase I ESA, APA search results, and building certifications into Ellty. Environmental advisors, lenders, and technical consultants each get tracked, watermarked access from one secure link.

Insurance and valuation

• Confirm current insurance covers the current commercial use; confirm transferability at closing
• Check SNIRH (Portuguese water resources information) flood risk maps for properties near the Tagus (Lisboa), Douro (Porto), or other major rivers
• Commission an independent valuation from a CMVM-certified appraiser; required for bank financing
• For coastal properties in Algarve or Setúbal: confirm cliff erosion and coastal flood risk from the Portuguese Environment Agency (APA) coastal risk maps

Seller KYC and AML

• Pull the RCBE (Registo Central do Beneficiário Efetivo) extract to confirm UBO disclosure for the selling entity
• Pull the RNPC commercial registration extract from IRN confirming the entity is in good standing
• Portuguese notaries and advogados are designated entities under AMLD5 and must perform KYC on all property transactions
• Confirm the selling entity has no outstanding AT tax debt or AT enforcement proceedings

How due diligence in Portugal works

Step 1 - Land registry and use license

Pull the certidão de teor and the caderneta predial simultaneously on day one. Cross-reference them. Portuguese registrations are managed by two separate systems and discrepancies are common, especially in older commercial buildings that have undergone informal works.

Request the licença de utilização from the Câmara Municipal at the same time. In Lisbon and Porto, response times vary from a few days to several weeks. If the license is missing, the timeline to regularize it must be built into the deal schedule.

Step 2 - IMT, IS, and VPT calculation

Calculate IMT on the higher of the transaction price or the VPT before making any offer. On a EUR 10M commercial asset, IMT at 6.5% is EUR 650,000, plus IS at 0.8% is an additional EUR 80,000. If the VPT is higher than the agreed price, the real IMT bill will exceed the estimate.

Confirm with your Portuguese tax advisor whether the transaction could qualify for IVA treatment (new building or opted transaction); this changes the IMT calculation. Your advogado handles the IMT guia and payment to AT.

Step 3 - Leases and NRAU compliance

Identify all existing tenants and their lease documentation. For any lease signed before the 2012 NRAU reform: check for indefinite protection or legacy renewal rights. These are relatively common in older Lisbon and Porto commercial buildings and directly affect the exit timeline.

Compare Spain's commercial lease framework if you run Iberian portfolio acquisitions. Both Spain and Portugal require notarized deeds, have separate land registry and fiscal registries, and have stamp duty equivalents (Spain's ITP or AJD vs. Portugal's IS). The key difference is Portugal's IMT at 6.5% vs. Spain's ITP at 6-11% (regional) for commercial.

Step 4 - Environmental review and building compliance

Commission Phase I ESA for any brownfield or former industrial site. Portugal's mining legacy is significant and not well-publicized; sites near the Iberian Pyrite Belt (Aljustrel, São Domingos) require specific assessment.

Confirm the CDE energy certificate is on file. Missing CDE delays closings; the notary appointment cannot proceed without it. Order it at the same time as the licença de utilização request.

Track all document requests and advisor reviews in real time via Ellty. You see which advisors are actively working on which files - and which ones have been reviewing the lease documentation repeatedly, signaling the issue before it surfaces in a due diligence report.

Step 5 - CPCV, notary, and escritura

Portuguese deals commonly use a Contrato Promessa Compra Venda (CPCV) - a binding promissory sales contract with a deposit of 10-20% - before the final escritura. If the seller defaults after the CPCV, the buyer receives double the deposit (sinal em dobro). If the buyer defaults, the deposit is forfeited.

The escritura is executed at the notary. The buyer pays IMT and IS to AT before the appointment. Title transfers to the buyer at the escritura. The advogado then registers the transfer in the Conservatória, which typically takes 1-3 weeks.

What makes Portugal different

Portugal has two separate property registries and both must agree. The Conservatória do Registo Predial is the legal land registry. The caderneta predial is the fiscal registry at the tax authority (AT). They're maintained independently. Any discrepancy - in the owner's name, the property description, or the area - signals an unregistered transaction or fiscal irregularity that must be resolved before the notary will proceed. This is the check that surprises most non-Portuguese buyers.

The VPT and IMT gap problem is endemic. IMT is calculated on the higher of the transaction price or the VPT. If the fiscal reference value (VPT) has not been updated in years, it may exceed the current market price. In that case, you pay IMT on a number higher than what you actually paid for the property. Always pull the caderneta and calculate the VPT gap before any commercial discussion.

The licença de utilização is not negotiable. No use license means no legal commercial occupation. In Portugal, the Câmara Municipal can enforce closure of unlicensed commercial premises. Missing use licenses in commercial buildings are common - particularly in renovated or converted properties in Lisbon and Porto historic centers - and regularization timelines are long and uncertain.

The CPCV structure creates a binary risk. Once you sign the promissory contract and pay the deposit, the buyer's downside is the deposit (typically 10-20% of the price) and the seller's downside is returning double the deposit. This creates strong mutual incentive to complete. But it also means all critical diligence must be done before the CPCV is signed - not between CPCV and escritura.

Timeline and cost in Portugal

Weeks 1-3 cover kickoff: certidão de teor, caderneta predial, licença de utilização request, CDE energy certificate check, IMT and VPT calculation, AT IMI clearance, and Phase I ESA engagement. Budget EUR 5,000-15,000 for advisory fees in this phase.

Load all files into Ellty before advisors start. Scoped, tracked links for each advisor eliminate the email document chase that adds weeks to Portugal CRE diligence timelines.

Weeks 3-6 cover deep review: lease abstraction, NRAU compliance check, building compliance review, planning violation investigation, Phase I ESA delivery, and CPCV negotiation. Cost runs EUR 10,000-30,000 depending on complexity.

CPCV signing: this is the binding step. Sign only when title, use license, VPT, and major planning items are confirmed.

Weeks 6-10 handle resolution: outstanding compliance items (licença regularization if needed), CDE if missing, IMT payment to AT, notary appointment, and escritura execution. Conservatória registration follows within 1-3 weeks of the escritura.

Portugal total acquisition cost: 6.5% IMT + 0.8% IS + legal fees EUR 10,000-30,000 + valuation + Phase I ESA if brownfield. Total acquisition cost on a Portuguese commercial deal runs approximately 7.5-8.5% of purchase price. Annual IMI at 0.3-0.45% of VPT is the ongoing tax obligation.
