Portugal buyer guide

Is Your CPCV Deposit Safe in Portugal?

The double-deposit rule is a legal remedy—not escrow, a refund service or proof that the seller can pay.

Part of Buy in Portugal: practical guides for foreign buyers who need clearer evidence before they commit.

A Portuguese contrato-promessa de compra e venda (CPCV) can make a property deal binding before the final deed. The buyer commonly transfers a substantial deposit directly to the seller.

That sentence should make you pause.

The usual reassurance is that Portuguese law lets the seller keep the deposit if the buyer defaults and lets the buyer claim twice the deposit if the seller defaults. The rule is real. The comforting version leaves out four things: the money is not necessarily protected, not every failed contingency is seller default, a contract can change the remedy, and a right to be paid is not the same as money collected.

Direct answer

If the seller says they need your deposit to fund their next house, next development or next unit, believe the risk information inside that statement: your money is being used as seller financing. That is not proof of misconduct. It is a reason to demand structural protection, reduce the amount at risk or walk away.

What a CPCV deposit actually is

A CPCV is a promise to enter into the final property purchase. It normally fixes the property, price, deposit, completion deadline, conditions and consequences of non-performance.

Under Civil Code article 441, money delivered by the buyer to the seller under a purchase promise is presumed to be sinal—earnest money or a deposit—even if the contract calls it an advance or part-payment.

A 2024 RFF Lawyers property-acquisition guide describes deposits of 5% to 20% as a general market range, while stressing that the percentage is negotiable and no law requires a deposit at all. It also describes the deposit as being paid directly to the seller, not the notary.

So “10% is standard” is not the end of the conversation. On an €800,000 purchase, 10% is €80,000 of buyer cash. The percentage may feel conventional. The exposure is personal.

What the double-deposit rule says—and what it does not

Article 442 of the Civil Code provides the familiar default framework:

• if non-performance is attributable to the buyer who paid the deposit, the seller may keep it; and
• if non-performance is attributable to the seller who received it, the buyer may demand twice the amount paid.

That shorthand describes the usual CPCV where the buyer has not taken possession. Article 442 also contains a different value-based remedy where the property has already been delivered to the buyer. Possession changes the analysis; have your lawyer apply the full article to the facts.

In qualifying cases, the buyer may instead seek execução específica under article 830: a court judgment that substitutes for the defaulting party’s declaration and forces the promised transaction through.

Those are meaningful remedies. They are not automatic deposit insurance.

A failed contingency is not automatically seller default

Suppose your CPCV makes the purchase conditional on mortgage approval, a satisfactory inspection, a missing license, a clean land-registry result or delivery of condominium documents. What happens if the condition fails depends on the exact drafting.

A well-written condition should say:

• what result is required;
• who must produce which evidence;
• the deadline and any extension right;
• how notice must be delivered;
• whether the contract terminates automatically or after a notice;
• whether the deposit is returned once or doubled; and
• how quickly repayment must be made.

The statutory double-deposit rule concerns non-performance attributable to the recipient of the deposit. An objectively failed financing condition may simply trigger a single return under the contract. A vague condition may create a dispute about whether it was satisfied, waived, prevented or invoked properly. Mere delay may not yet be definitive breach.

“Your contingency protects you” is incomplete unless your independent lawyer can point to the words that explain how the money comes back.

The contract can change the practical answer

A reported Lisbon Court of Appeal decision from December 2013 shows why the full contract matters.

The buyers agreed in 2010 to buy a house that was still to be built and paid €79,000 in deposit installments. The property was not completed by the agreed period. In January 2012, the buyers terminated and demanded €158,000—double the deposit.

The first-instance court awarded the double deposit. The appeal court agreed that the seller had definitively failed and could not shift responsibility to its contractor. But it held that the CPCV had validly replaced the statutory double-deposit remedy with return of the original €79,000 plus interest.

The appellate decision arrived almost two years after the termination notice. The published judgment does not tell us when, or whether, the buyers collected the money.

Why a legal right can still become a collection problem

There is no general CPCV account where the deposit waits untouched for the deed. If you pay the seller and the seller uses the money, your original cash is gone from the transaction.

If repayment is due and the seller cooperates, the transfer may be simple. If the seller disputes the trigger, lacks liquidity or refuses to pay, your legal path may involve a lawyer’s demand, a lawsuit, possible appeal, and enforcement against assets. A court judgment is powerful. It is still not a bank transfer.

An April 2026 Portuguese Ministry of Justice release reported that civil cases completed in first-instance courts averaged 21 months in 2025—the lowest average in 23 years. The same release said pending first-instance cases rose 4.1% during 2025, with civil justice the main source of the negative case-flow balance.

That 21-month figure is not a CPCV forecast. A dispute may settle quickly, take longer, be appealed or require a separate enforcement phase. It is enough to reject the idea that the court system functions like a fast refund desk.

Insolvency changes the terrain

If the seller becomes insolvent while both sides still have obligations, articles 102 and 106 of Portugal’s Insolvency and Company Recovery Code become relevant. The general rule suspends an incompletely performed bilateral contract until the insolvency administrator chooses whether to perform it. If performance is refused, the buyer’s rights are handled within the insolvency regime.

There is a stronger rule for a property promise with eficácia real—effect against third parties—where possession has already been delivered to the buyer. That is not the usual resale CPCV where the buyer pays a deposit but receives no keys before the deed.

Civil Code article 755 likewise links a buyer’s right of retention to having obtained possession. Do not assume that paying a deposit alone makes you a secured creditor.

Have your lawyer assess the actual priority and insolvency consequences of any proposed protection. Do not ask for early possession merely to chase a legal advantage; it can create separate occupancy, liability, insurance and tax problems.

What you can learn about the seller before paying

Property due diligence can establish much more than “the seller owns it.” A current land-registry record can show registered ownership, mortgages, attachments and other registered burdens. Your lawyer can verify identity and authority, property and tax records, licensing or use documents, and the condominium file. If the seller is a company, commercial and insolvency records may add useful information.

But that is not the same as underwriting the seller’s ability to refund you.

Ordinary buyer due diligence will not normally reveal a private seller’s complete balance sheet, all debts, spending plans or future liquidity. Company filings are historical and do not prove that your deposit is segregated. A clean title record says something important about the property at the time checked. It does not say where your transfer goes the next morning.

Ask two different questions:

1. Can this seller transfer clean title to this property?
2. If the deal fails, what assets or security make repayment realistic?

The first is standard conveyancing work. The second is credit risk.

“The seller needs your deposit for the next deal”

In property purchases CitrusNest has evaluated, agents have said that the owner needed the CPCV deposit to place money on another property. In another kind of deal, the explanation was that an architect or builder needed the money for another transaction or later units in the building.

Those explanations may be completely honest. They are still not reassuring.

A seller who relies on your deposit to complete another purchase creates a chain: your recovery may depend on their next seller, their financing, their closing and their willingness or ability to unwind the sequence. A developer who uses deposits as working capital adds construction, sales and project-finance risk.

This does not mean every chained sale or off-plan project fails. It means the buyer should stop treating the deposit as a passive placeholder. If your cash must leave the deal for the seller’s plan to work, your protection should not depend only on a promise to replace it later.

Why online anecdotes cannot tell us the odds

We could not locate a public national dataset counting CPCV deposits paid, transactions that fail, deposits returned voluntarily, lawsuits filed or amounts eventually recovered. Reported court decisions capture disputes that produced a published ruling, not every successful closing, private settlement or abandoned claim.

Sparse complaints do not prove CPCVs are safe. A collection of bad stories does not prove failure is common. There is no reliable denominator.

It is also too simple to say the system works through pure luck. A CPCV creates binding obligations and serious consequences for breach. The accurate conclusion is less comforting: the incidence of failure is unknown, while the structure of an ordinary direct-to-seller deposit makes the downside clear.

Protections to negotiate before you transfer money

Have an independent Portugal-based lawyer tailor the structure. Start with these questions.

1. Can we finish the risky due diligence first?

Complete the legal, condominium, technical and financing work that could change the decision before the CPCV whenever possible. Read incomplete condominium minutes as a buyer warning, not as paperwork to fix after money moves.

If something must remain open, name it as a condition. “Subject to due diligence” is not a procedure.

2. Can we reduce the amount and time at risk?

A deposit is negotiable. Ask for a smaller percentage and the shortest realistic period between CPCV and deed. On a development, do not accept calendar-based installments with no independently verified construction milestone or protection.

3. Can an independent third party hold the money?

Ask whether the seller will accept a properly documented escrow or client-funds arrangement with a mutually accepted independent, regulated professional. Confirm that the proposed holder can lawfully provide the service, whose client the holder is, where the money sits, what protection applies, and the exact release and refund triggers.

Do not assume that an agent’s account, the seller’s lawyer or the word “escrow” in an email creates neutral protection. If true third-party holding is unavailable, ask what bank guarantee or other enforceable security can replace it.

4. Can the promise be protected against third parties?

Civil Code article 413 permits a promise to be given eficácia real when the required declaration, form and registration are used. Ask your lawyer whether that, provisional acquisition registration or another registration is appropriate.

Registration may protect the promised purchase against some third-party events. It does not put the deposit back in your bank account or solve every insolvency issue.

5. Does the clause explain repayment like an operations manual?

For each condition and breach scenario, the CPCV should make the amount, evidence, notice, deadline, payment account, interest or penalty, and dispute path as clear as possible. Ask what facts would establish definitive breach rather than delay.

Send notices exactly as the contract requires. Keep the signed contract, bank proof, emails, registry records and every delivery receipt.

6. What happens if the seller spends it or cannot pay?

Ask this before signing, not after default. If the only answer is “you get double under Portuguese law,” the collection question remains unanswered.

Our verdict

A CPCV can be a useful contract. The problem is not the three-letter acronym. The problem is confusing a legal remedy with custody of cash.

If repayment would require the seller to find new money, price the CPCV as credit risk.
