Buying residential property in Portugal, whether you are an EU/EEA citizen or a non-EU (third-country) national, follows the same broad legal sequence: obtain a NIF (tax number), open a Portuguese bank account, sign a promissory contract (Contrato de Promessa de Compra e Venda, CPCV) with a deposit, complete legal and technical due diligence on the property, sign the final deed (escritura) before a notary or at a "Casa Pronta" one-stop desk, and register the new ownership at the Conservatória do Registo Predial (Land Registry). Non-EU/EEA buyers follow an identical property-law process — there is no separate legal track for them — but they typically need a fiscal representative in Portugal to obtain and hold a NIF while resident abroad.
Skipping or rushing any step — especially due diligence on the property's legal and fiscal status — is the most common source of disputes and financial loss for foreign buyers. Understanding the sequence up front lets you plan timelines (NIF, bank account, and possibly a mortgage all have to be in place before the CPCV deposit is at real risk) and know which professionals (lawyer, notary, real estate agent) get involved at each stage.
Key Facts
A NIF (Número de Identificação Fiscal) is a prerequisite for nearly everything else: opening a bank account, signing contracts, and paying property taxes. Without it you cannot legally buy property in Portugal.
Any individual, resident or non-resident, may request a NIF from the Autoridade Tributária e Aduaneira (Tax and Customs Authority).
If you do not have a tax domicile (fixed residence) in Portugal, you generally need a fiscal representative (a person or firm with a Portuguese address) to obtain and maintain your NIF.
The CPCV (promissory contract) is not legally mandatory but is standard market practice; it fixes the price, deposit, and deadline for the final deed, and sets contractual penalties for either party pulling out.
The final deed (escritura) can be executed at a notary, a lawyer's office, or through the "Casa Pronta" one-stop government service, which can combine deed and registration in a single visit.
After the deed, the property must be registered in the buyer's name at the Conservatória do Registo Predial to be legally effective against third parties.
Tax costs (IMT transfer tax, Imposto de Selo stamp duty, notary/registration fees) apply on top of the purchase price — see the companion "Portugal — Property Closing Costs" document for current rates, since these figures change with each state budget.
Steps
1. Obtain a NIF — Apply at a Portuguese tax office (Serviço de Finanças), a Loja de Cidadão, or via a lawyer/fiscal representative acting on your behalf if you are abroad. Non-EU/EEA residents without a Portuguese tax domicile generally need to appoint a fiscal representative resident in Portugal at the time the NIF is issued.
2. Open a Portuguese bank account — Most sellers, notaries, and tax payments expect funds to move through a Portuguese account. You will need your NIF and identification documents to open one; a mortgage application (if used) is typically tied to the same bank.
3. Property search and reservation — Once you have identified a property, some agencies request a reservation deposit before drafting the CPCV; this is a market practice, not a legal requirement, and terms vary by agency.
4. Due diligence — Before signing the CPCV, verify the property's legal and fiscal status: the Certidão Permanente (permanent land registry certificate, confirming legal owner, registered mortgages/liens, and pending registrations), the Caderneta Predial Urbana (fiscal record showing the Valor Patrimonial Tributário and property description), the Ficha Técnica da Habitação (technical file, for buildings from 2004 onward), and the Certificado Energético (energy performance certificate), which by law must be made available to the buyer before both the CPCV and the final deed are signed. If the property is in a condominium, also check for outstanding condominium fees or disputes.
5. Sign the CPCV and pay the deposit (sinal) — The CPCV sets out the price, the deposit amount, and the deadline for the final deed. Under Article 442 of the Civil Code, if the buyer defaults, the deposit is generally forfeited; if the seller defaults, the seller must generally repay double the deposit. Deposit size is negotiated freely between the parties — see closing-costs.md for typical market ranges.
6. Arrange financing (if applicable) — If using a mortgage, the bank will require its own property valuation (avaliação bancária) before issuing a binding loan offer. This step must be coordinated with the CPCV deadline — see mortgage.md for how bank timelines interact with the deed date.
7. Final deed (escritura) — The deed transfers ownership and is signed before a notary, a lawyer with the relevant powers, or at a Casa Pronta desk. IMT and Imposto de Selo must be paid (or their payment proven) before the deed can be executed.
8. Register the property — After the deed, register the change of ownership at the Conservatória do Registo Predial. Using the Casa Pronta service, deed and registration can often be completed on the same visit.

Common Mistakes
Starting the CPCV before the NIF and bank account are in place, causing delays at the deed stage.
Not verifying the Certidão Permanente independently and relying only on the Caderneta Predial, which reflects fiscal — not full legal — status.
Treating the CPCV deposit percentage as fixed by law; it is a negotiated market convention, not a statutory rate.
Assuming non-EU buyers face a different legal purchase process — the property-law steps are the same; the practical difference is mainly the need for a fiscal representative and, if relevant, financing/residency considerations.
