Accurate as of September 2026. This is a general guide to standard practice, not legal advice — your own lawyer will confirm exactly what applies to your specific purchase.
Our guide to property due diligence in Portugal covers what those checks are actually protecting you from. This one is more practical: the specific list your lawyer should be working through, so you know what a thorough job looks like and can ask the right questions if something feels rushed.
What documents does a lawyer request on the property side?
At minimum, four core documents: the Certidão de Registo Predial (or Certidão Permanente) confirming current ownership and any registered debts or encumbrances; the Caderneta Predial Urbana, the tax register entry; the Licença de Utilização, confirming the building is approved for residential use; and, for anything built or substantially altered since 2004, the Ficha Técnica da Habitação — a technical file describing the construction, materials, and installations, which by law has to be handed to the buyer at completion for properties it applies to.
What documents apply specifically to apartments?
A declaração de não dívida de condomínio, confirming the seller owes nothing in condo fees, plus recent condominium meeting minutes if your lawyer thinks it's worth requesting them — these often surface planned works or special assessments before they become your problem. Your lawyer should also confirm the apartment's fracção (unit designation) in the registry matches the actual unit you're buying, which sounds obvious but occasionally doesn't line up in older buildings that have been informally subdivided or renumbered over the years.
What documents does my lawyer need from me?
Your NIF (Portuguese tax number) is the starting point — you cannot sign a CPCV or complete a purchase without one. If you're not resident in Portugal you may also need a fiscal representative, and if you won't be present for signing, a power of attorney (procuração) authorising your lawyer or another representative to sign on your behalf. Our guide to NIF, Portuguese bank account and power of attorney covers what to arrange and when, since several of these steps need lead time from overseas.
What about proof of funds?
Portuguese lawyers and notaries are required to carry out anti-money-laundering checks, so expect to be asked for proof of the source of your funds — this might be a bank statement, a sale-proceeds letter from a previous property sale, or documentation of an inheritance or gift, depending on where the money is coming from. This isn't unique to Portugal and isn't a reflection on you personally; it's a standard compliance step, and it moves faster if you have the documentation ready before your lawyer asks for it rather than after.
What happens at the CPCV stage specifically?
Before you sign the Contrato de Promessa de Compra e Venda (promissory contract), your lawyer should have already reviewed the core property documents above, confirmed there's no adverse entry on the registry, and negotiated the specific conditions and deposit terms that go into the contract itself — what happens if you can't get financing, what happens if a defect is found, what the completion date is. We've got a dedicated, in-depth guide to the CPCV coming shortly, covering deposits and conditions in full — worth waiting for if you're not yet at this stage.
What's checked again right before completion?
A good lawyer re-checks the Certidão de Registo Predial shortly before deeds, not just at the start of the process — a lot can happen in the weeks between signing a CPCV and completing, and a fresh certificate confirms nothing has changed (a new charge registered, a dispute filed) in the interim. They'll also confirm any conditions from the CPCV have genuinely been met — an existing mortgage discharged, a repair completed — before advising you to proceed to signing.
How do I know if my lawyer is actually doing all this?
Ask directly, early, and in writing: which documents have you requested, and what have you found so far? A lawyer working properly on your behalf will have a clear, specific answer — document names, what each one showed, and anything outstanding — rather than a general reassurance that "everything looks fine." If you're still choosing representation, our guide on choosing a lawyer in Portugal has the specific questions worth asking before you sign a power of attorney with anyone.
FAQ
What is a Ficha Técnica da Habitação and do I need one? It's a technical file describing a building's construction, materials, and key installations, legally required for properties built or substantially renovated from 2004 onward. If it applies to your purchase, the seller is legally obligated to provide it, and your lawyer should confirm it's been handed over at or before completion.
Do I need a NIF before I start viewing properties, or just before I buy? You'll need it before you can sign a CPCV, open a Portuguese bank account, or complete a purchase, so it's worth arranging early rather than at the last minute — it can take longer to obtain from overseas than buyers expect, and delays here can hold up an otherwise-ready purchase.
Why does my lawyer need proof of where my money came from? Portuguese lawyers and notaries are legally required to carry out anti-money-laundering checks on property transactions, the same as in most European countries. It's a standard compliance step, not something specific to your purchase, and having documentation ready in advance keeps the timeline moving.
Does my lawyer check the property documents again right before I sign the deed? A thorough one does. Registry entries can change in the weeks between signing a promissory contract and completing, so a fresh check of the Certidão de Registo Predial shortly before deeds confirms nothing new has been registered against the property in the meantime.
What's the difference between this list and general property due diligence? Our guide to property due diligence in Portugal explains what each check is protecting you from and why it matters. This post is the practical companion — the specific list of documents involved, so you can follow along with your own lawyer's process and know what thorough looks like.
