Renting an Apartment in Lisbon: Contracts, Deposits and Scams
The Lisbon rental market moves fast, which is exactly when newcomers sign things they should not. These are the rules and checks that protect you before you pay.
Renting a home in Lisbon means signing a written lease (contrato de arrendamento) that the landlord registers with Finanças, and paying rent against receipts, usually electronic ones issued on the Portal das Finanças. Before you pay anything, check that the person renting the flat has the right to do so and that every payment is in the contract.
Portuguese rental law sits mainly in the Civil Code and the New Urban Lease Regime (Novo Regime do Arrendamento Urbano, NRAU). It has been amended many times since 2019, and courts do not always read the newest rules the same way. The points below are as of November 2026 and are general information, not legal advice.
What kinds of lease exist and how long do they last?
A residential lease is either for a fixed term (prazo certo) or open-ended (duração indeterminada). Fixed-term leases for a permanent home generally run for at least one year, with exceptions for temporary needs such as studies or a work posting.
Fixed-term leases renew automatically unless one side gives notice in time. The Civil Code also sets rules on how long the renewal lasts and when a landlord may refuse the first renewal, and appeal courts have disagreed on whether a contract can set shorter periods. If your contract has an unusually short term or renewal clause, ask a lawyer (advogado) or a tenants’ association to read it before you sign. Our guide to tenant rights in Portugal covers notice periods and what a landlord can and cannot do during the lease.
How much can a landlord ask up front?
Expect a request for the first month’s rent, some months paid in advance and a security deposit (caução). Article 1076 of the Civil Code regulates both advance rent and the deposit, but official sources we checked in November 2026 give different versions of the current caps, so verify the limit in the consolidated Civil Code on Diário da República, or with a lawyer, before you agree to large sums.
Whatever you pay, write it into the contract: how many months of advance rent, the deposit amount and the conditions for returning it. A deposit guarantees your obligations and is not a prepayment of rent.
| Up-front item | What to check |
|---|---|
| First rent and advance rent | Number of months stated in writing; receipt for each payment |
| Deposit (caução) | Amount and return conditions in the lease |
| Guarantor (fiador) | Who signs, for how long and for what amount |
| Agency fee | Who hired the agent and who pays; ask for an invoice |
Is a guarantor required?
The law does not require a guarantor, but many Lisbon landlords ask for one, often a resident of Portugal with income here. A guarantor (fiador) is personally liable for your debts under the lease, so read that clause carefully.
Newcomers without a local guarantor often negotiate other options, such as a larger deposit within the legal limit or a bank guarantee. Whatever you agree must be in the contract.
How is the lease registered and how do rent receipts work?
The landlord registers the lease with Finanças and pays the stamp duty on it; the tenant does not file the registration. Ask the landlord for the proof of registration, because you may need it for residence applications, address changes and housing support.
Most landlords must issue an electronic rent receipt (recibo de renda eletrónico) on the Portal das Finanças for each payment. Those receipts are what lets Finanças count your rent toward the tenant deduction in your annual IRS tax return. If you never see receipts in your tax area, raise it with the landlord early. Paying by bank transfer to an account in the landlord’s name gives you a second record.
How do I spot a rental scam?
The classic scam is a flat that cannot be visited, offered below market price, with a request to pay a deposit to reserve it. Warning signs:
- The “owner” is abroad and asks for money before any visit or key handover.
- Payment is requested by wire to a foreign account, by crypto or by a money transfer service.
- The same photos appear in other listings, or the address is vague.
- There is pressure to decide today and refusal to sign a contract first.
- The person cannot show ID that matches the property owner or a written mandate from the owner.
Before paying, ask for the owner’s name and check it against the property’s land registry record (certidão permanente do registo predial), which the owner can share with an access code. Pay only after a visit and a signed contract. Report scams to the police (PSP) and keep every message.
Where do official rent figures come from?
The national statistics institute, INE, publishes rent statistics for new lease contracts by municipality and parish, based on lease data reported to Finanças. Those figures are medians per square metre for a given period, so they describe the market rather than any single flat. Find them on the INE statistics portal under housing rents.
Advertised prices on property portals are asking prices, not signed rents, and are usually higher. Rent increases during a lease follow a yearly coefficient; see our guide to the rent increase limit in Portugal.
Bottom line
In Lisbon, the documents protect you more than the price does: a written contract, proof that Finanças has it, a receipt for every euro and an owner whose name matches the land registry. Walk away from any offer that asks you to skip one of them.
FAQ
Do I need a NIF to rent?
Yes, in practice: the landlord needs your tax number to register the lease. See our guide to getting a NIF in Portugal.
Can a landlord refuse me because I am a foreigner?
Discrimination based on nationality or ethnic origin is prohibited in Portugal. Landlords can still check income and ask for guarantees, applied equally to all applicants.
Is a verbal agreement valid?
Portuguese law requires residential leases to be in writing. Without a written lease you will struggle to prove your address, register with services or claim tax deductions.
Who pays utilities?
The contract says who pays. Usually the tenant pays electricity, gas, water and internet, and the building’s condominium fees stay with the owner.
