Buying Property in Portugal — Legal Guide for Foreign Buyers

The buying process in Portugal — step by step

1. Obtain a NIF (Portuguese tax number). Required for any property transaction. Non-EU residents typically appoint a fiscal representative. See our NIF guide.
2. Open a Portuguese bank account. Not strictly required to buy, but practical for paying taxes, utilities, and the IMI annually.
3. Find a property and make an offer. Most offers are verbal initially. Once accepted, a brief reservation agreement may be requested by the agent — review before signing or paying anything.
4. Engage a property lawyer. Before paying any deposit. The lawyer's first job is to verify the property exists in registry and tax terms as described.
5. Due diligence. The lawyer searches the Conservatória do Registo Predial, reviews the Caderneta Predial, checks habitation license, identifies any mortgages, debts, or third-party rights.
6. Sign the CPCV. Promissory contract of purchase and sale, signed by both parties, with a 10–30% deposit. This is where the deal is made.
7. Mortgage (if applicable). Mortgage approval and bank coordination, typically 4–6 weeks.
8. Final payment and escritura. Before a Portuguese notary, the deed is signed, IMT and stamp duty are paid, the balance is transferred, and the property is registered in the new owner's name.
9. Post-completion. Register the new ownership at the Conservatória do Registo Predial. Update Finanças for IMI billing.

Documents you will need

For the buyer, the documentary requirements are modest:

• Valid passport (and visa or residence permit if applicable).
• Portuguese NIF (tax number).
• Proof of address in your home country.
• Proof of funds — bank statements showing the source of the purchase money. Required for anti-money-laundering compliance.
• Mortgage pre-approval letter, if mortgage-financed.
• Power of Attorney, if signing remotely.

The heavier documentary burden is on the seller. Your lawyer collects, verifies, and reviews the seller's documents — the Caderneta Predial, the Registo Predial, the habitation license, the energy certificate, the condominium statement, and any specific licensing for pools or annexes.

Costs and taxes when buying property in Portugal

Annual cost after purchase: IMI (annual municipal property tax, 0.3%–0.8% of taxable value).

The CPCV — Contrato Promessa de Compra e Venda

The CPCV is the most important contract in the Portuguese property process. It is binding, requires a deposit, and locks in completion terms. Once signed, walking away typically means losing the deposit. If the seller walks away, the buyer is generally entitled to double the deposit back — but enforcing that often requires litigation.

A well-drafted CPCV should:

• Identify the property unambiguously by Registo Predial number and Caderneta Predial article.
• State the price, deposit, and balance clearly.
• Set a firm completion date with consequences for delay.
• Include conditions precedent — mortgage approval, satisfactory due diligence, clearance of any identified issue.
• Treat the deposit clearly — held in escrow if appropriate, signal vs. non-signal payment.
• Address default symmetrically — what happens if the buyer defaults vs. what happens if the seller defaults.

A poorly drafted CPCV — particularly one provided by the seller or agent without independent review — is the single most common reason a foreign buyer loses money on a Portugal property transaction. See our CPCV guide for details.

The escritura — final deed

The escritura is the final deed of sale, signed before a Portuguese notary. By the time you reach the escritura, all due diligence should be complete, all conditions of the CPCV should be satisfied, all taxes should be paid, and all funds should be ready to transfer.

At the escritura: the notary reads the deed in Portuguese, the parties (or their attorneys-in-fact) sign, the balance of the purchase price is transferred, and ownership transfers. The deed is then registered at the Conservatória do Registo Predial. See our escritura guide.

Legal risks foreign buyers face

The risks that recur most often in foreign-buyer transactions in Portugal:

1. Paying a "reservation" deposit before any legal review. The reservation fee is rarely refundable in practice.
2. Signing a CPCV with weak buyer protections. Deposit terms that punish the buyer asymmetrically.
3. Buying property with undisclosed debts or mortgages. Tax debts, condominium debts, and bank mortgages travel with the property.
4. Illegal construction. Pools, annexes, basements, extensions added without permit. Cannot be retroactively legalised in many cases.
5. Land classification. Rustic land sold with the implication that construction is possible, when it is not.
6. Inheritance disputes. Property sold by a seller who has not completed the inheritance process from a deceased owner.
7. POA defects. Power of Attorney that does not legally cover the specific act required, causing the escritura to fail on the day.

For each of these, see our pitfalls guide.

When to hire a property lawyer in Portugal

Ideally, before you sign anything — including a reservation agreement. The earliest engagement is the most valuable, because the lawyer's job is to identify problems while you still have leverage. See our property lawyer Portugal page for typical scope and fees.

In practice, the most common engagement points are:

• Before the CPCV. Optimal. Lawyer conducts due diligence, drafts or negotiates the CPCV, sets up POA if remote.
• After offer accepted, before CPCV signed. Still useful. Lawyer reviews the proposed CPCV and conducts due diligence.
• After CPCV signed, before escritura. Defensive. Lawyer verifies the CPCV is being executed correctly and prepares for completion.
• Already signed CPCV, problem discovered. Difficult but possible. Options narrow but action is still better than inaction.
