Where a Spanish purchase becomes binding
Reservation, deposit contract, notary, registry: what each stage is for, and which one commits you.
In Spain you are usually committed weeks before the deed is signed, and before any public official is involved. Buyers from Northern Europe arrive with a sequence borrowed from home, in which little is settled until completion. That is the misreading. Once you see what each stage is for, the order makes sense.
What follows is the ordinary shape of a resale purchase. Figures and timings vary by region and by case, and the ones that apply to you belong with a lawyer or a gestor who has read your file.
The reservation, and what the registry shows
After a viewing, the first document is usually a reservation. You pay a modest sum and the property comes off the market for an agreed period. Its purpose is not to bind you to the purchase but to buy time: time for your lawyer to examine the property on paper before you commit anything substantial.
Note who the estate agent acts for. Here the agent is usually instructed and paid by the seller. That does not make them dishonest; it does mean they are not your adviser.
The first request is the nota simple, an extract from the Land Registry. It is short and it answers a short list of questions: who the registered owner is, what the registry believes the property to be — description, recorded surface, boundaries — and what is attached to it. Mortgages, charges, embargoes, rights of way, restrictions imposed by a developer or by the community of owners.
Reading it is as much about what is missing as about what is there. It describes the registered position, not the physical one. Building work carried out and never declared does not show up. Neither do unpaid community fees, arrears of council tax, or how the town hall classifies the plot. The registry and the cadastre are separate systems and they do not always agree. Each of those is a separate enquiry, and together they are the work of the period you have just bought.
The deposit contract
Next comes the private purchase contract with a deposit, the contrato de arras. This is the pivot, and the point most buyers underestimate, because it feels informal. No official is present.
Spanish law recognises more than one kind of deposit and they behave differently. The form common in residential sales lets either side withdraw at a price: a buyer who pulls out forfeits the deposit, a seller who pulls out returns it twice over. Other forms give no right to walk away — the disappointed party can insist the sale goes ahead. Which one you have signed is a matter of wording, and the wording is not always obvious in translation.
The deposit is negotiated rather than fixed, and normally large enough that losing it would hurt. That is what makes the contract work. The same document fixes the completion date, records what is included in the sale, allocates costs and sets out the conditions.
Conditions matter here more than anywhere else in the process. If your purchase depends on a mortgage, on an occupancy document, on undeclared building work being regularised, or on a charge being cancelled before completion, it has to be written in now. After signature your position is the one you agreed to. This is why the due diligence sits before the deposit contract and not after it.
The weeks between arras and notary are working weeks. The bank completes its valuation, your lawyer clears what was left unresolved, and the money comes into Spain. That last part is regularly underestimated. Moving a large sum across borders takes longer than a domestic transfer, and Spanish banks will ask where it came from — a question answered with documents, not assurances. You will also need an NIE, the identification number Spain issues to foreigners, and in practice a Spanish bank account.
The notary, and the weeks after
Completion takes place at the notary's office. A notario is a public official, neither your representative nor the seller's. He or she checks identity and capacity, confirms the deed contains what the law requires, reads it out and witnesses the signing. The impartiality is the point. It also means nobody at that table is looking after your interests except the adviser you brought with you.
On the day, the notary requests a fresh extract from the registry, so the position is confirmed at the moment of signing rather than as it stood weeks earlier. An existing mortgage is normally cancelled at the same table, paid off out of the purchase money, with the seller's bank represented. Payment is usually by banker's draft or confirmed transfer. The escritura is signed and the keys change hands. If you cannot attend, a power of attorney can be arranged beforehand.
One point to raise with your lawyer well before that day. Where the seller is not resident in Spain, the buyer withholds a portion of the price and pays it to the tax authority on the seller's account. It is the buyer's obligation, not a favour.
Signing is not the end of it. Transfer tax has to be paid within a set period, and the deed then lodged at the Land Registry. Registration is not what makes you the owner — the deed does that — but it is what makes your ownership good against everyone else. Notice of the signing normally reaches the registry electronically straight away, which gives some protection while the full entry is processed. That takes weeks. The work is usually handled by a gestor, an administrative specialist who files the tax, sees the registration through and moves the utilities and the council tax record into your name. Some law firms do it in-house. Either way, agree beforehand who is responsible: a deed sitting in a drawer helps nobody.
The document that decides how the rest of it goes is the one signed in an office with no official present.
