Buying a Used Car in Portugal

Last verified: October 2026.

Who this is for

  • You live in Portugal, EU or non-EU, and want to buy a car that already has Portuguese plates.
  • You are choosing between a dealer and a private seller.
  • You hold a residence card rather than a Portuguese citizen card, so you will register the car in person.

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

Updated October 2026. From 1 January 2027, road tax (IUC) is no longer due in the car's registration month. The owner on 1 January pays for the year, on fixed dates.

To buy a used car in Portugal, you check its legal record, pay by traceable means, insure it, and register it in your name within 60 days. An online record check costs €10. Registering online is 15% cheaper than at a registry office, but it needs a Portuguese citizen card, so most foreign residents register in person. A dealer must give you a legal warranty of three years, or 18 months if you agree in writing. A private seller gives you no legal warranty.

Dealer or private seller

You can buy from a dealer (stand) or a private seller (particular). The registration is the same. What changes is your protection.

If you buy from a dealer:

  • You get the legal warranty for consumer goods. It is three years. For a used car, the dealer can cut it to 18 months, but only if you both agree.
  • Ask whether the dealer will file the registration for you, and whether that is in the price.
  • If the dealer offers finance, compare it with a loan from your own bank.

If you buy from a private seller:

  • The consumer warranty does not apply. It covers only sales by a business to a consumer.
  • You do the registration yourself, with the seller's help.
  • Prices are often lower, so 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 registry authority, IRN (Instituto dos Registos e do Notariado), keeps this record.

Anyone can order the certificate on the Automóvel Online site (automovelonline.mj.pt) without logging in. You need only your name, an email address, and the 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:

  • The owner is the seller. The name must match the seller's identity document. If it does not, stop.
  • No retention of title (reserva de propriedade). This means a bank or finance company keeps ownership until a loan is paid. It must be cancelled before you can register the car.
  • No other charges. Look for a mortgage-style charge (hipoteca) or a court seizure (penhora). Either can block or complicate the sale.
  • The plate and chassis number match the car. Check the number stamped on the car itself.
  • Pending requests. The online certificate also shows registration requests still being processed.

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

Check the record 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). Many people still call it the DUA (Documento Único Automóvel). Older cars may have two papers instead: the livrete and the title of ownership (título de registo de propriedade).
  • The latest inspection sheet (ficha de inspeção), if the car is old enough to need inspection. It shows the result and the next due date.
  • Proof that road tax (IUC) is paid. The seller can print it from the tax portal, Portal das Finanças.
  • The seller's identity document, so you can check it against the record.
  • Proof that any finance is cleared, if the record shows a retention of title. The lender issues it.
  • All keys, the manual, and the service record.

Check the car itself

  • Inspection status. If the next inspection is due soon, ask the seller to do it first, or negotiate the price.
  • Inspection defects. A car can pass with minor defects. Ask what they were and whether they were fixed.
  • Mileage. Each inspection sheet records the odometer reading. Compare past sheets with the dashboard. A big gap is a warning sign.
  • A mechanic's check. If you are unsure about the car, pay a garage to look at it before you commit.
  • Accident history. Ask directly whether the car was ever written off and rebuilt.

Paying for the car

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

Pay by bank transfer or a bank cheque. Keep proof of payment with the car's papers. Pay only once you have the documents and a clean 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 what makes you the legal owner on the register.

What it costs

IRN sets the registration fee in its fee regulation. Registering online on Automóvel Online costs 15% less than registering at a counter. If you register after 60 days, you pay more. Check the current amounts on IRN's costs page before you go.

Online, if you both hold a Portuguese citizen card

Online registration needs the digital certificate on a Portuguese citizen card (Cartão de Cidadão) and a card reader. Lawyers, solicitors, and notaries can also file online with their professional certificates. Most foreign residents hold a residence card instead, so they cannot use this route themselves.

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 citizen card and confirms the sale. If both confirm online, no papers need to be sent.
  3. You get a Multibanco payment reference. Pay within five days, or the request is cancelled.
  4. The registry deals with the request within two working days of payment.
  5. The new registration certificate is sent to you.

Filling in the online request takes about 15 to 20 minutes.

In person, for everyone else

Go to a registry office that handles vehicles. This can be a vehicle registry (Conservatória do Registo Automóvel) or a citizen shop (Loja do Cidadão) with an IRN desk. You can also send the request by post. Bring:

  • The vehicle registration request form (Requerimento de Registo Automóvel), filled in and signed by buyer and seller. You can download it from the Justice Ministry's site.
  • Both people's identity documents. A passport or residence card is fine.
  • Both people's tax numbers (NIF).
  • The car's current registration certificate.

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

If the buyer does not register

After 60 days, the seller can register the sale in the buyer's name. The seller does this with documents that show the sale, such as an invoice or receipt with the plate, names, and addresses. So register promptly, or the seller may do it for you, and you will still owe the fee.

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 motor policy sold in Portugal must meet these minimums.

If you were insured in another country, ask your old insurer for a claims history statement covering the last five years. Insurers must provide it within 15 days of your request. A clean history may lower your premium. See Getting Car Insurance in Portugal for cover types.

Road tax (IUC) after you buy

Road tax (IUC) is a yearly tax on the car's registered owner. Fully electric cars are exempt.

Until the end of 2026, IUC is due by the end of the car's registration month each year. The registered owner at that time pays it. If you buy just before that month, the tax for that year will usually be yours.

From 2027, the rules change:

  • The owner of the car on 1 January pays the tax for the whole year.
  • In 2027, bills up to €500 are paid in October. Larger bills are paid in two parts, in July and October.
  • From 2028, bills are paid in April. Bills over €100 can be split between April and October. Bills over €500 can be split into April, July, and October.

So from 2027, a car you buy in, say, March has already been taxed to its previous owner for that year. Agree in writing how you will share that cost, if at all.

After registration, log in to the Portal das Finanças and check the car appears under your NIF. See Paying Road Tax (IUC) and Passing the Inspection (IPO) for the rates.

Inspection (IPO)

A car on the road must pass its periodic inspection (inspeção periódica obrigatória, or IPO). For an ordinary passenger 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 next due date is on the latest inspection sheet. The inspection centre's fee for a light vehicle is €30.46 plus VAT.

If something goes wrong

If you bought from a dealer, the legal warranty applies. You can ask for:

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

If a fault appears in the first two years, the law presumes it was there when you took the car. If you agreed to the shorter 18-month warranty, that presumption lasts one year. After that, you must show the fault existed at delivery.

Tell the dealer in writing, by letter or email, so you have proof. If the dealer refuses, contact a consumer arbitration centre. Most are free or cheap, and the Justice Ministry lists them by region. They try mediation first, then an arbitrator decides.

If you bought from a private seller, the consumer warranty does not apply. Your only route is a claim under general civil law, which 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 cancel 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 sale needs inheritance tax and heirs' documents. Only a lawyer, solicitor, or notary can file these online. Expect delays.
  • The car is on foreign plates. It is not on the Portuguese register yet, and vehicle tax may be due. Read the import guide linked above.

Your checklist

  1. Order the online certificate and check the owner, charges, plate, and chassis number.
  2. See the registration certificate, inspection sheet, and IUC proof.
  3. Have the car checked, and compare the 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 car appears under your NIF, and note the next inspection date.
