Buying a Used Car in Portugal

How to check a used car's papers, pay safely, register it in your name within 60 days, insure it, and use your warranty when you buy from a dealer.

Buying a Used Car in Portugal

Last verified: September 2026.

Who this is for

  • Residents, EU or non-EU, buying a car already registered in Portugal.
  • Buyers choosing between a dealer and a private seller.
  • Foreign residents without a Portuguese Cartão de Cidadão, who must register the car in person.

Not for you if: you are bringing a car from another country or buying one still on foreign plates. Read "Importing a Car to Portugal" instead.

Updated September 2026. From 2027, road tax (IUC) will no longer fall due in the car's registration month. Parliament approved a fixed yearly calendar in April 2026.

Buying a used car in Portugal means checking the car's legal record, paying by traceable means, insuring it, and registering it in your name within 60 days. Registration costs €55.30 online or €65 in person, and €65 more if you are late. Only Cartão de Cidadão holders can register online, so most foreign residents go to a registry office. A dealer must give you a legal warranty of at least 18 months. A private seller gives you none.

Dealer or private seller

You can buy from a licensed dealer (stand) or from a private seller (particular). The paperwork is the same. What changes is your protection and who does the work.

If you buy from a dealer:

  • You get a legal warranty. It is three years, or 18 months if you agree in writing to the shorter period.
  • The dealer usually files the registration for you. Ask whether the fee is in the price.
  • The dealer may offer car finance. Compare it with a loan from your own bank.

If you buy from a private seller:

  • There is no legal warranty. You rely only on the general rules of civil law about hidden defects, which are hard to enforce.
  • You do the registration yourself, with the seller's cooperation.
  • Prices are often lower, but the checks below matter even more.

The most important check is the car's permanent registration certificate (certidão permanente do registo automóvel). It shows the current owner and any charges on the car. The Registos e Notariado (IRN), the registry authority, keeps this record.

You can get the certificate online at automovelonline.mj.pt without logging in. You need only your name, email address, and the car's number plate. It costs €10 and gives you six months of online access. A paper certificate from a registry office costs €17.

Check these points on the certificate:

  • The owner is the seller. The name must match the seller's identity document. If it does not, stop.
  • No reserva de propriedade (retention of title). This means a bank or finance company still owns the car until a loan is paid. It must be cancelled before you can register the car.
  • No hipoteca (charge), penhora (court seizure), or arresto (freezing order). Any of these blocks or complicates the sale.
  • The plate and chassis number match the car. Check the chassis number stamped on the car itself.

The online certificate shows only current registrations, not the history of past owners. For the full history, ask a registry office for a paper certificate.

Pull the certificate again on the day you pay. A charge can be registered at any time.

Documents the seller must give you

Ask to see these before you agree a price, and take them when you pay:

  • The registration certificate (Certificado de Matrícula, still widely called the DUA or Documento Único Automóvel). Older cars may have two papers instead, the livrete and the título de registo de propriedade. Both versions are valid.
  • The latest inspection certificate (IPO), showing the result and the next due date.
  • Proof that road tax (IUC) is paid. The seller can print this from the Portal das Finanças.
  • The seller's identity document, so you can check it against the registration record.
  • Proof that any finance has been cleared, if the certificate shows a retention of title. The lender issues this.
  • All keys, the manual, and the service record.

Check the car itself

  • Inspection status. The car must have a valid inspection. If the next inspection is due soon, ask the seller to do it first or reduce the price.
  • Inspection result. A car can pass with minor defects. Ask what they were and whether they were fixed.
  • Mileage. Each inspection report records the odometer reading. Compare past reports with the dashboard. A big gap is a warning sign.
  • A mechanic's check. For any car you are unsure about, pay a garage to inspect it before you commit.
  • Write-off history. Ask directly whether the car was ever declared a total loss and rebuilt. Commercial history reports can help.

Paying for the car

The law bans cash payments of €3,000 or more for any transaction. This applies between private people too. If you are not resident in Portugal and are not buying as a business, the limit is €10,000.

Pay by bank transfer, instant transfer, or a bank cheque. Keep proof of payment with the car's papers. Pay only when you have the documents and the cleared record in hand.

Registering the car in your name

The buyer must register the change of owner within 60 days of the sale. This is the step that makes you the legal owner.

What it costs

How you registerWithin 60 daysAfter 60 days
Online (Automóvel Online)€55.30€120.30
In person at a registry office€65€65 plus the €65 late charge

Registering online is 15% cheaper than in person.

Online, if you both hold a Cartão de Cidadão

Online registration at automovelonline.mj.pt needs the digital certificate on a Portuguese Cartão de Cidadão, read with a card reader. The site does not currently offer login with the Chave Móvel Digital. Most foreign residents hold a residence card instead, so they cannot use this route.

For a private sale, it works like this:

  1. The buyer logs in and fills in the car and seller details.
  2. The seller logs in with their own Cartão de Cidadão and confirms the sale.
  3. You receive a Multibanco reference. Pay it within five days, or the request is cancelled.
  4. The registry processes the request within two working days of payment. You get an email and a text message.
  5. The new registration certificate is posted to your address.

The online form takes about 15 to 20 minutes.

In person, for everyone else

Go to a registry office that handles vehicles. This can be a Conservatória do Registo Automóvel, or a Loja do Cidadão or Espaço Registos with an IRN desk. Bring:

  • The official request form (Requerimento de Registo Automóvel), filled in and signed by buyer and seller. You can download it from justica.gov.pt.
  • Both parties' identity documents. Foreign residents bring a passport or residence card.
  • Both parties' NIF (tax number).
  • The car's current registration certificate.

It is easiest if buyer and seller go together. If the seller cannot come, ask the office in advance what they must provide.

You receive a provisional document on the day, which lets you drive until the new certificate arrives by post.

If you do not register

If the buyer does not register within 60 days, the seller can register the sale in your name with proof of the sale. The seller can also ask the registry to have the car seized. Either way, you pay more. Register promptly.

Insurance from the first day

Car insurance does not pass to you with the car. You need your own compulsory third party policy before you drive away.

The law sets minimum cover of €6.45 million for injury and €1.3 million for damage to property. Every policy sold in Portugal meets these minimums.

If you had insurance in another EU country, ask your old insurer for a claims history statement. Insurers must provide it within 15 days of your request. A clean history can lower your premium. Our guide "Getting Car Insurance in Portugal" covers cover types and prices.

Road tax (IUC) after you buy

Road tax (IUC) is an annual tax on the car's registered owner. It does not change the price of the purchase.

Until the end of 2026, IUC is due by the last day of the car's registration anniversary month. The person who owns the car when it falls due pays it. If you buy just before the anniversary month, the tax for that year will usually be yours.

Parliament approved a new calendar in April 2026:

  • In 2027, a transitional year, IUC is paid in October. Larger bills can be split into two instalments.
  • From 2028, IUC is due by the end of April. Bills over €100 can be split into two payments, and bills over €500 into three.

After registration, log in to the Portal das Finanças and check that the car appears under your NIF. Our guide "Paying Road Tax (IUC) and Passing Vehicle Inspection in Portugal" explains the rates.

Inspection (IPO)

A car must pass a periodic inspection (inspeção periódica obrigatória, or IPO) to be on the road. For an ordinary car the timetable is:

  • First inspection four years after first registration.
  • Then every two years until the car is eight years old.
  • Then every year.

The date of the next inspection is on the current certificate. Driving with an expired inspection leads to a fine.

If something goes wrong

If you bought from a dealer, you have the legal warranty. If a fault appears in the first two years, the law presumes it existed when you took the car. You do not have to prove it. You can ask for:

  • Repair or replacement, as a first step.
  • A price reduction or cancelling the sale, if repair or replacement is impossible or fails.

Tell the dealer in writing, by letter or email, so you have proof. If the dealer refuses, write a complaint in their complaints book (Livro de Reclamações). You can also go to the motor sector's arbitration centre (Centro de Arbitragem do Sector Automóvel), which settles disputes with car dealers and garages.

If you bought from a private seller, there is no warranty. Your only route is a claim under general civil law for hidden defects the seller knew about. That usually needs a lawyer. The checks before you pay are your real protection.

Special cases

  • The car still has finance on it. The lender must release its retention of title before you can register. Arrange the sale with the lender, or pay the lender directly and get the release document.
  • The seller inherited the car. If the heirs never registered it in their names, the registration needs tax and inheritance documents. Only a lawyer, solicitor, or notary can file those online. Expect delays.
  • The car is on foreign plates. It is not yet on the Portuguese register, and vehicle tax may be due. Read "Importing a Car to Portugal".

Your checklist

  1. Get the online certificate and check the owner, charges, plate, and chassis number.
  2. See the registration certificate, inspection certificate, and IUC proof.
  3. Have the car checked, and compare mileage with past inspections.
  4. Agree the price and pay by bank transfer.
  5. Take out insurance before you drive.
  6. Register the car in your name within 60 days.
  7. Check the IUC appears under your NIF, and note the next inspection date.
