The Four Checks That Decide Whether You Should Buy That Spanish Property

Due diligence on a Spanish property purchase means four separate checks, run in the three-to-four-week window between reservation and signing contract. The land registry confirms who owns the property and whether it carries debts. The town hall confirms it was built legally and remains so today. The community’s statutes and minutes reveal your future obligations as an owner. A final check confirms all bills and taxes are paid up. Fail any one, and the purchase should stop, with your deposit refunded.

Chapter one: who owns it, and is it clean

The land registry answers the first questions within a day. The nota simple, Spain’s registry extract, shows who legally owns the property. It confirms the description matches what you actually viewed. It also flags anything attached to it: mortgages, charges, liens, embargoes, debts. This is the fastest of the four checks and the least negotiable. In Spain, debts like these attach to the property, not the person. Skip this check, and you can inherit the seller’s problems along with the keys.

Chapter two: was it built legally, and is it still legal

The town hall holds the second answer, and it comes in two parts that buyers routinely conflate. The licence of first occupation certifies the building matched its approved plans when completed, with services in order. But that’s a snapshot from the year it was built. Legality decays over time: an owner encloses a terrace, another converts a garage, a third extends the kitchen, and none of it goes through a licence.

So the check has a second part: confirmation that the town hall has no open infringement against the property today. This risk survives an entirely honest seller, because the alteration may predate them, and it grows with every change of hands. The older the property and the more owners it’s had, the more this chapter matters — worth remembering if you’re drawn to character stock like the casco antiguo of Estepona or the mature villas of Guadalmina Baja.

Chapter three: the community you’re marrying

Buy an apartment or a townhouse, and you’re not just buying walls — you’re joining a small legislature. The third check reads the community’s statutes and the last two years of general meeting minutes. It’s consistently the most underrated of the four. The statutes tell you the rules, including any restrictions on how you can use or let the property.

The minutes tell you the future: the special levy being discussed for the facade, the dispute simmering with a neighbour, the vote being organised about holiday rentals. Nobody wants to become an owner and discover a month later that the community just approved a levy every owner must fund. The minutes are where that surprise gets caught in advance.

Chapter four: the bills that come with the keys

The final check confirms the property’s running accounts are clean: property tax, community fees, water, electricity. Unpaid amounts here have a way of attaching themselves to the property, and therefore to you. It’s the least glamorous chapter and the quickest to verify. Skipping it is how buyers end up paying someone else’s arrears in their first month of ownership.

Why it takes weeks, and why that’s fine

Four chapters, four different counterparties: registry, town hall, community, and utilities and tax offices. Each has its own response times. That’s why proper due diligence takes three to four weeks, and why the reservation stage exists at all. A modest deposit, held in escrow with a subject-to-due-diligence clause, buys exactly the window these checks need, with a full refund if any chapter fails. The output is binary by design. Positive, and you proceed to contract with confidence. Negative, and you walk away having spent nothing but a few weeks.

Seen whole, the four chapters are Spain’s answer to the question every foreign buyer quietly carries: what if something is wrong and I can’t tell? Something can always be wrong. The system’s reply is that each kind of wrong has a check designed to find it, provided someone is retained to run them, a point we’ve made at length in our piece on what the notary does and doesn’t do.

Slot these four weeks into the full purchase sequence and you get the real promise of the Spanish system: not that nothing is ever wrong, but that you find out before it’s yours, whether you’re buying a first apartment or something from our golf selection.

These checks matter at the tax stage too — see what’s changing in Andalucía’s property tax rules — and they matter again if you ever sell, when the break-even number comes due.

Questions people are asking

What does due diligence cover when buying property in Spain?

Four checks: land registry ownership and debts, town hall building legality, the community’s statutes and meeting minutes, and confirmation that taxes and utility bills are paid up.

How long does due diligence take in Spain?

Three to four weeks, the window between signing the reservation and signing the private purchase contract. Each check goes to a different institution, which is why it takes this long.

What is a nota simple?

Spain’s land registry extract. It confirms who legally owns the property, that the description matches what you viewed, and flags any mortgages, charges or liens attached to it.

Can I inherit debts on a Spanish property I buy?

Yes, if due diligence isn’t done properly. In Spain, debts like unpaid community fees or utility bills attach to the property itself, not to the previous owner, so they can pass to you along with the keys.

Why does the community’s meeting minutes matter when buying an apartment?

They reveal what’s coming: a special levy being discussed, a dispute with a neighbour, a vote on holiday rentals. The statutes tell you the rules; the minutes tell you the future.

What happens if due diligence finds a problem?

The purchase should stop, and with a properly drafted reservation held in escrow, your deposit is refunded in full.
