From October 1st 2026, any contract transferring ownership of an urban property in Portugal must state explicitly whether the property holds an urban title. The duty falls on the notary, registrar, lawyer or licensed conveyancer drawing up the deed, and failure to include the statement makes the transaction voidable. A property without an urban title can still be sold. What is no longer possible is selling without disclosing.
For buyers coming from abroad, this is the most consequential change in Portuguese property transactions in recent years, because it puts in writing something that until now depended entirely on how thorough a buyer’s own due diligence happened to be.
What an urban title is, and why it has no exact equivalent abroad
The urban title, título urbanístico, is the document proving that a building work, a construction, an extension or an alteration, was licensed by or formally notified to the municipality. It is the documentary evidence that what stands on the ground corresponds to what was approved.
It is not the same as the habitation licence, the land registry certificate or the tax record, though all of these travel together in a Portuguese property file. Buyers from the United Kingdom, the United States or northern Europe often assume that a registered title implies planning compliance. In Portugal these are separate questions, and registration says nothing about whether building works were ever authorised.
What changes on October 1st 2026
Decree Law 108/2026 of 29th of May introduces the twenty first amendment to the Portuguese planning and building code, and takes effect on the 1st of October 2026, a date set by the postponement approved in Decree Law 155-B/2026 of 31st of July. Until September 30th the previous regime applies.
On the transaction side, the new wording requires that, in any transfer of urban building land, of completed or unfinished buildings, or of their autonomous units, the professional drawing up the deed must record one of three statements:
- That the corresponding urban title exists, where it is produced to them.
- That the seller declares holding the urban title, where it is not produced.
- That the seller declares not holding an urban title.
Omitting the statement renders the transaction voidable.
Does this stop unlicensed properties from being sold?
No, and this is the most common misreading of the new rules.
The law does not prohibit selling a property without an urban title. It requires that the situation be declared. An owner without a title may sell, provided the deed says so expressly.
For an international buyer, the practical effect is different from the legal one. Signing a deed that states the property holds no urban title means accepting that position knowingly, and later claiming ignorance becomes very difficult. It also has consequences worth anticipating: Portuguese banks assess lending against the documentary position of the property, and a future resale will face the same declaration and the same scrutiny.
The questions a buyer should ask before making an offer
The moment to raise this is before an offer, not at the deed.
Whether the property holds a corresponding urban title, and whether the seller can produce it. Whether any alterations have been made since the building was completed, and whether those alterations were licensed or notified. Whether what is physically on site matches the approved plans, particularly in terms of the number of units, layout and any enclosed outdoor space. And, where the property sits in a rehabilitation area or a protected zone, whether additional approvals were required.
These questions belong to a lawyer engaged by the buyer. Property purchases in Portugal are routinely completed with independent legal representation, and for anyone buying from abroad this is not an optional refinement.
Older Lisbon buildings deserve particular attention
In Lisbon’s historic districts, Alfama, Graça, Mouraria, Bairro Alto, Príncipe Real, much of the housing stock predates the modern licensing framework, and decades of interior alterations, balcony enclosures and attic conversions were carried out with no municipal process at all.
This does not make those properties unsellable, and it does not make them bad purchases. It does mean that the documentary position needs to be established before an offer rather than after, and that the answer depends on the nature of the work, the date it was carried out and the rules in force at the time. The new decree also changes the regime governing the invalidity of licensing decisions, including for situations already in place, which makes case by case analysis more important rather than less.
This article sets out the general framework and is not a substitute for legal advice on a specific property.
What sellers who live abroad should do now
Owners of Portuguese property who live elsewhere should treat this as a reason to open the file early. Locating the urban title of a property bought fifteen years ago, or establishing what happened to a renovation carried out by a previous owner, takes considerably longer from another country, and municipal archive requests are not fast.
Starting that work before the property is marketed avoids the worst version of this problem: a buyer under contract, a completion date fixed, and a document that nobody can find.
Frequently asked questions
When does the urban title disclosure requirement take effect?
On October 1st 2026, the date set by Decree Law 155-B/2026 of the 31st of July, which postponed the entry into force of Decree Law 108/2026. Until September 30th 2026 the previous regime applies.
Can a property without an urban title still be sold in Portugal?
Yes. The law requires the absence of a title to be expressly declared in the deed. What carries the sanction of voidability is the omission of the statement, not the absence of the title itself.
Is the urban title the same as the habitation licence?
No. They are separate documents answering different questions, although both normally form part of the same property file in a sale.
Does this affect buyers who are not Portuguese residents?
The rule applies to the property and the transaction, not to the nationality or residence of the parties. It applies equally to every buyer and seller of urban property in Portugal.
