Not long ago, a client from abroad came to us convinced he had found the deal of the year. It was an old house a short walk from one of the island's most sought-after beaches, at a price that left plenty of room for a full renovation and a healthy profit when he sold. The seller had been reassuring: "Don't worry, it's entirely legal, everything is in order."
Before signing, the buyer asked us to take a look. We reviewed the documentation, the Town Council's archives and the records of the Mallorca Territorial Protection Agency (ADT). We also checked historical aerial photographs, the entry in the Property Registry, the Cadastre file and the legality of the utility connections, and we inspected the property on site. The conclusion was clear: the property's real planning status was very different from what he had been told. The house was not legal. The renovation he was counting on could not be carried out, and the resale plan went with it. Had he signed, he would have ended up with a property he could neither improve nor easily sell, and a serious financial loss.
His story is not unusual. We come across versions of it regularly, especially with properties on rustic land. The seller who says "it's all legal" or "it's all in order" usually believes it.
Behind this phrase lies one of the issues that causes the most concern in our day-to-day work: the gap between what the Property Registry says about a home and its real planning status. A buyer who doesn't understand that gap can, without realising it, purchase a property that carries hidden planning irregularities, severe limits on what can be done with it, or even the risk of demolition.
- What the Registry tells you, and what it doesn't
Every purchase contract begins by describing the property, and that description largely mirrors the Property Registry (Registro de la Propiedad). The Registry is a very reliable source for who owns a property and what charges, such as mortgages or liens, are attached to it. It also records the property's description and, where its georeferenced plot has been registered, its location and boundaries.
What catches people out is that the Registry's control over a property's urbanistic status is limited. A home can appear perfectly clean in the Registry and still have been extended without a licence, built in breach of planning rules, or be the subject of an enforcement file that has not been recorded there. Clean in the Registry and legal to use are two very different things.
- The trap that confuses almost everyone: "registered, therefore legal"
This is the one we wish more people knew about. Under Spanish law, a building can be entered in the Property Registry and in the Cadastre even if it never had a building licence. There is a special route for registering constructions that are old enough that the authorities' time limit to order their demolition has already expired: the so-called "time-barred" buildings.
On paper, the result looks just like a fully legal home: "building registered." But that doesn't mean it was legally built. It means the clock ran out.
The clock running out also doesn't mean the building is free of consequences. Buildings in this situation are usually subject to significant restrictions. Extensions, major renovations and changes of use are often limited and, in some cases, not allowed at all. For a buyer planning to renovate, that can end the whole project.
There is usually a clue, if you know where to look. When a building is registered this way, the registrar must notify the local council, and that notification is recorded in the Registry and shown in the registry extract (nota simple). The council is then meant to record the building's specific planning status and restrictions in the Registry, although in practice that doesn't always happen. Either way, buyers do not always read that far.
- In Mallorca, the stakes are higher
The Balearic Islands take a notably strict line. As a general rule, the authorities have eight years from the completion of illegal building works to act against them, longer than in many other Spanish regions.
On rustic land (suelo rústico), that limit has not existed since 2018. The power to act against illegal building never expires, so an illegal building on rustic land never quietly becomes safe.
There is, however, a way out for some properties. Decreto Ley 3/2024, of 24 May, introduced an amnesty procedure that allows owners to apply, over a three-year period, to legalise certain old buildings on rustic land. It applies to time-barred constructions, and the owner must:
- submit a technical legalisation project,
- pay a penalty and the municipal fees, and
- meet certain technical requirements.
Whether a specific property qualifies depends not only on its land classification but also on its records and history, so each case needs to be checked individually.
For a buyer, the lesson is simple. With a rustic property in Mallorca, "is it registered?" is not enough. You also need to know what type of land it sits on, when and how it was built, and what you will be allowed to do with it.
At Palma Lawyers, this is one of our core areas of practice. Before you commit, we review the property's full planning status, so you know exactly what you are buying and what you will be able to do with it.
