Lovely House. Whose Field Is That?
Sometimes a Spanish property comes with three different versions of itself: the one standing in front of you, the one shown on Catastro, and the one described in the deeds and Land Registry.
Ideally, they agree. Occasionally, they appear never to have been properly introduced.
The swimming pool is enjoying a perfectly successful existence in the garden but hasn’t made it onto all the paperwork. The land measurements don’t match. A wall everyone has accepted as the boundary for forty years takes a completely different route on the plan.
And sometimes the investigation involves an adjoining field and a ruin nobody expected to be discussing.
This is the point where buying or selling becomes less about floor tiles and considerably more about finding out exactly what you’ve got.
The paperwork, without the headacheYou’ll hear three names regularly: Catastro, escritura and Registro de la Propiedad. They have different jobs, which is why looking at just one won’t give you the whole picture.
Catastro is an administrative property record used for purposes including taxation. It contains information such as location, surface area, buildings and mapped parcel boundaries. It’s extremely useful, especially when you’re trying to understand how a house sits within its land, but it isn’t a substitute for checking ownership or planning status.
The escritura is the public deed documenting a transaction, such as the purchase of the property. It includes the description used when that deed was signed, which may be considerably older than the kitchen you’re admiring.
Historic boundary descriptions can require a little patience. “The land of Señor García” becomes less helpful when nobody remembers Señor García and his former almond field is now three houses and a roundabout.
The Registro de la Propiedad, or Land Registry, records ownership and registered rights affecting the property. A current nota simple gives an informative summary of the registered description, ownership and matters such as mortgages or other registered rights and restrictions.
Your lawyer compares these records, alongside the relevant technical and Town Hall information. Where the descriptions differ, the job is to establish why and what needs to happen next.
How does a house end up disagreeing with itself?Older fincas and village houses may have changed hands long before modern surveying and mapping. Boundaries followed paths, trees, irrigation channels or walls. Measurements were recorded using older methods, and later changes weren’t always reflected in every record.
An extension might have been added. A road widened. Neighbours might have reached an informal arrangement about a strip of land without completing the paperwork to match.
Or a former agricultural building might have gradually developed windows, plumbing and a rather convincing kitchen.
An explanation is useful. “It’s always been like that” is not the end of the investigation.
A discrepancy doesn’t automatically mean the property is illegal or that the sale cannot proceed. Some issues involve outdated descriptions or mapping errors; others raise questions about ownership, boundaries or building works. The cause matters, because the solutions can be very different.
Sometimes you need someone with measuring equipmentWhen the land area or boundaries are uncertain, a suitably qualified surveyor or topographer can measure the site and compare it with the plans and documentation.
That survey provides evidence to help the legal investigation. It doesn’t, by itself, settle ownership of disputed land.
It may establish that the charming stone wall everyone assumed marked the boundary is simply a charming stone wall. Attractive, certainly. A complete answer to the legal question, perhaps not.
For the buildings, an architect or another appropriately qualified technical professional can investigate how the house, pool and outbuildings compare with the records, and what planning questions need checking with the Town Hall.
A pool appearing on Catastro does not, by itself, establish that the necessary permissions exist. Equally, an old ruin on a plan is not a promise that you can restore it into the guest cottage of your dreams.
It might be possible. That is what the checks are there to establish.
Buying? Ask before you commitYou don’t need to become an expert in Spanish property records. You do need an independent lawyer and, where necessary, the right technical professionals.
If something doesn’t match, ask what causes the difference, what it affects, whether it can be resolved, and who will handle the work and cost. Establish the proposed route and timing before you sign a reservation or purchase contract or pay a deposit.
“We’ll sort it out later” is not a due-diligence strategy.
Nor does a wonderful view make an unanswered paperwork question disappear, however tempting it might be to keep looking out of the window.
Selling? Give yourself a head startThe best time to investigate a discrepancy is before a buyer discovers it halfway through their checks.
If the pool is missing from the records, find out what is required. If the land measurements differ significantly, get advice. If an extension was added years ago, establish its position rather than hoping nobody asks.
Some matters take time, involve neighbours or require more than one procedure. Understanding them early helps you describe the property accurately, set realistic expectations and avoid unnecessary surprises when a sale is progressing.
You don’t have to arrive with every answer. Start by getting the documents together.
And yes, sometimes there is a pleasant surpriseProper investigation can occasionally establish that a property includes more land than its owners realised, or clarify the position of an overlooked parcel or building.
But a larger shape on a screen isn’t the moment to announce that you’ve acquired an orchard. First, establish that it belongs to the property and have the position properly documented.
Whether the outcome is reassuring, inconvenient or unexpectedly good, the aim is the same: understand exactly what is being sold and what is being bought.
At Renvida, we’re happy to talk about terraces, kitchens and where you’ll put the outdoor table. We also believe in asking the less glamorous questions and involving the right people when something needs investigating.
Because helping someone move starts well before moving day.
