Buying property in Portugal is straightforward only when the legal, tax, planning and physical records all describe the same thing you think you are buying. Treat the estate-agent listing as marketing, not due diligence. Before committing money, verify ownership, charges, tax records, planning/licensing, condominium position and—especially for rural or mixed property—the actual boundaries and registered parcels.

Start with the right professionals

An estate agent can help find and negotiate a property, but the agent is not a substitute for independent legal and technical due diligence. If an agency is involved, verify its AMI licence using IMPIC’s official licence search. Consider using an independent Portuguese lawyer or solicitor (solicitador) whose duty is to you, particularly if you are buying remotely, using a power of attorney, buying rural land or signing a CPCV before finance and due diligence are complete.

Do not confuse the main property records

  • Certidão permanente predial: the land-registry record. It shows registrations affecting the property and pending registration requests. Justiça says it is continuously updated during its six-month validity. Request it through Justiça/Predial Online.
  • Caderneta predial: the tax-property record held by Finanças, including the tax identification of the property and VPT. It is not a replacement for land-registry proof of ownership. See Portal das Finanças property records.
  • Planning/licensing records: the Câmara Municipal can hold licences, approved plans and other planning records. Check that the property and its actual use match what is legally authorised.
  • Physical reality: walls, annexes, pools, outbuildings, terraces, access roads and plot boundaries on the ground can differ from registry, tax or planning records. Investigate discrepancies before signing.

A sensible due-diligence sequence

  1. Identify the seller and legal owner. Compare the seller’s identity and authority with the land-registry record.
  2. Check registrations and encumbrances. Review mortgages, liens, usufruct, seizures, pending registrations or other rights appearing on the certidão.
  3. Compare registry and tax descriptions. Check article/fraction numbers, area, use and VPT against the caderneta and the actual property.
  4. Check planning and use. Confirm licensing/dispensation, approved plans and whether alterations or annexes are lawful.
  5. Inspect physically. A bank valuation is not a structural survey. Consider an engineer/architect/building inspection where condition or alterations matter.
  6. Check condominium issues. For apartments, review condominium rules, recent minutes, planned works and seller debt evidence.
  7. Check tax/cost consequences. Calculate IMT, stamp duty, registration, legal/notarial and mortgage costs before making the offer financially binding.
  8. Only then finalise the CPCV and deposit. Build necessary conditions into the contract instead of relying on verbal promises.

The CPCV: where buyers often take the biggest risk

The Contrato-Promessa de Compra e Venda (CPCV) is commonly used before the final deed. Do not treat it as a harmless reservation form. Under Civil Code Article 442, where a payment is treated as sinal, default can have serious consequences: a buyer at fault may lose the deposit; where the seller is at fault, the buyer may in qualifying circumstances claim double the amount paid. Get the wording reviewed before transferring the deposit.

Make the CPCV deal with the points that actually matter: exact property identification, price and payments, deadline for completion, vacant possession/tenancies, mortgages or other charges, included contents, necessary documents, responsibility for existing debts, planning/licensing issues and what happens if mortgage approval or defined due-diligence conditions fail. If finance is essential, do not assume a generic CPCV automatically protects you if the bank later refuses the loan.

Taxes and purchase costs

Portugal normally charges IMT and Imposto do Selo on a purchase. The Tax Authority states that IMT is generally calculated on the higher of the acquisition value and the property’s VPT, with rates depending on the type/use of property and other factors. Stamp duty on the acquisition is currently 0.8% of the relevant taxable value. If there is a mortgage, separate stamp duty can also apply to the credit. Use the Tax Authority’s current house-purchase page and current tables rather than an old online calculator.

For eligible first-time buyers aged 35 or under purchasing their own permanent home, an IMT/stamp-duty relief regime may apply within statutory limits. The limits are indexed and change; verify the current amounts and eligibility immediately before completion rather than relying on a figure copied months earlier.

Completion: escritura / authenticated document and registration

The final transfer can be completed through the appropriate deed/authenticated-document route and registered. Casa Pronta is the Justice/IRN one-stop service for property transactions and registration. Its current document guidance includes identification/tax details and, where applicable, building/use documentation and the property’s energy certificate. Do not leave registry follow-up as an assumption: ownership protection depends on proper registration.

Energy certificate, use licence and alterations

Ask for the current energy certificate where required and verify that the physical property matches the documents being used for the transaction. Older buildings and later alterations can create exceptions or additional documentation questions. Casa Pronta’s official checklist specifically addresses use-licence evidence/dispensation and energy certification. If an extension, garage, pool or annex appears absent from approved records, investigate before committing to buy.

Apartments: check the condominium before you inherit the problem

For a fraction in a condominium, ask for the condominium declaration and supporting evidence concerning charges, arrears and approved works, and read recent meeting minutes. A low monthly condominium fee does not mean there are no major works planned. Confirm which amounts belong to the seller and which future obligations attach to the fraction after completion.

Rural and mixed property needs extra scrutiny

Rural Portugal can expose differences between what a seller points to on the ground and what is actually registered. A tax entry alone does not prove title or exact boundaries. BUPi explains the identification/georeferencing system for rural and mixed properties and stresses that registration in the Conservatória is what protects property rights. Check every article/parcel being sold, access rights, boundaries, water sources, easements and whether buildings on rustic land are legally recorded and licensed. Guide #126 will go much deeper into rural-property due diligence.

Mortgages: approval, valuation and the CPCV are separate

A bank may approve you in principle and later value the property differently, request more documentation or reject the specific collateral. Do not confuse a bank valuation with legal due diligence or a technical survey. Where the purchase depends on finance, have your adviser/lawyer ensure the CPCV reflects the finance risk you are actually willing to take.

Common warning signs

  • Pressure to pay before you or your representative sees the key property documents.
  • The bank account receiving the deposit does not match the party or arrangement described in writing.
  • The seller cannot explain differences between registry, caderneta and physical boundaries.
  • “Everyone builds like this here” is offered instead of planning evidence.
  • A rural access road crosses another property with no clear legal right of access.
  • The agent’s AMI number cannot be verified on IMPIC.
  • A seller refuses to provide a current certidão or condominium information.
  • You are told a lawyer is unnecessary because the agent/notary/bank “checks everything”.

Before you transfer a CPCV deposit

  • Verify the seller’s identity and ownership/authority.
  • Obtain/review the current certidão permanente predial.
  • Compare the caderneta predial and registry descriptions.
  • Check mortgages, seizures, usufruct and pending registrations.
  • Verify the estate agent’s AMI licence where applicable.
  • Check licensing/planning and physical alterations.
  • For apartments, check condominium debt and planned works.
  • For rural/mixed property, verify every parcel and boundary.
  • Calculate IMT, stamp duty and completion costs.
  • Confirm mortgage/finance conditions if relevant.
  • Have the CPCV reviewed independently and make conditions explicit.
  • Use traceable payments and retain signed receipts/evidence.
