Buying property in Spain runs through a fairly fixed sequence: pre-purchase checks, an earnest-money deposit contract (contrato de arras), signing a public deed (escritura pública) before a notary, and registration at the Registro de la Propiedad. Foreign buyers — resident or not — must first obtain a Número de Identidad de Extranjero (NIE), since Spanish law requires every party to a real-estate transaction to be identified with a tax/foreigner ID number. A gestor, abogado, or gestoría is not legally required but is near-universal in practice for handling paperwork and tax filings.
The transaction mechanics determine when money changes hands, when a buyer is legally exposed (arras stage), and when ownership is actually protected against third-party claims (registration). Newcomers unfamiliar with the arras/escritura/registro sequence — or without an NIE arranged early — commonly face delays or lose deposits over avoidable missteps.
Key Facts
The **escritura pública** (public deed of sale) must be formalized before a Spanish notary; buyer and seller are free to choose which notary to use.
Registration at the **Registro de la Propiedad** is technically not compulsory to transfer ownership between the parties, but it is what gives a buyer legal protection ("seguridad jurídica") against undisclosed third-party claims or hidden debts on the property — in practice it is always done.
Before filing at the Registro de la Propiedad, three documents are needed: the notarial copy of the escritura, proof that the regional transfer tax (ITP) or equivalent has been self-assessed and paid, and proof that the municipal capital-gains tax (plusvalía municipal) has been filed.

The **contrato de arras** (earnest-money/deposit contract) is governed by Article 1454 of the Spanish Civil Código Civil: if arras are agreed and no other function is specified, they are treated as "arras penitenciales" — the buyer can walk away and forfeit the deposit, or the seller can walk away by returning double the deposit.
An **NIE (Número de Identidad de Extranjero)** is mandatory for any foreign buyer, resident or non-resident, and is needed to sign the escritura, open a Spanish bank account, pay taxes, and set up utilities.
For mortgaged purchases, the purchase deed signing and the mortgage loan drawdown normally happen simultaneously at the notary's office.
A registered notary/registry check ("nota simple") from the Registro de la Propiedad shows current ownership, charges, and encumbrances on a property and is the standard pre-purchase due-diligence document.
Steps
1. Pre-purchase due diligence — Obtain a "nota simple informativa" from the Registro de la Propiedad (available online via registradores.org) to confirm the seller's ownership and check for existing mortgages, liens, or encumbrances.
2. Reservation / holding deposit (contrato de reserva) — In practice, many transactions begin with an informal reservation agreement and a small holding deposit to take the property off the market while due diligence and financing are arranged. This step is a market custom rather than a distinct legal category set by statute.
3. Arras contract (deposit/earnest-money agreement) — Buyer and seller sign a contrato de arras and the buyer pays a deposit (commonly around 10% of the price, though the amount is negotiated, not fixed by law). Under Civil Code Article 1454, unless the contract states otherwise, either party can withdraw — the buyer loses the deposit, or the seller must return it doubled.
4. Apply for an NIE (if not already held) — Foreign buyers apply for the NIE through the Dirección General de la Policía — either from abroad via a Spanish consulate/embassy, or in Spain via an Oficina de Extranjería or police station, using form EX-15.
5. Arrange financing (if applicable) — If using a mortgage, the lender must complete a valuation (tasación) and issue binding loan offer documentation before the loan can close. (See the companion mortgage.md document for detail on this step.)
6. Sign the escritura pública — Buyer, seller (or their representatives), and — for a mortgage — the lender's representative attend the notary to sign the public deed of sale. The notary verifies identities, checks the nota simple, and reads out the deed's terms.
7. Pay the transfer taxes — The applicable regional transfer tax (ITP for resale property, or IVA + AJD for new-build) must be self-assessed and paid before the deed can be registered. (Full detail in the companion closing-costs.md document.)
8. Register at the Registro de la Propiedad — The escritura, tax payment proof, and plusvalía filing proof are filed at the Registro de la Propiedad — either in person, through a gestoría, or telematically by the notary. Once correctly filed, the registrar has **15 business days** to qualify and complete the inscription.
Timelines
NIE application processing: maximum 5 business days from filing, per Spanish immigration procedure rules (though in-person appointment availability can extend the real-world wait considerably).
Registro de la Propiedad inscription: 15 business days ("hábiles") from correct filing of documents.
Required Documents
Passport/national ID and NIE
Nota simple (property registry extract)
Signed contrato de arras (if used)
Proof of funds / mortgage approval (if financing)
Escritura pública (drafted and signed at notary)
Proof of ITP/IVA+AJD payment

Common Mistakes
Not applying for an NIE early enough, causing delays at the notary appointment.
Signing an arras contract without understanding that walking away forfeits or doubles the deposit under Civil Code Article 1454.
Skipping the nota simple check and missing an existing mortgage or embargo on the property.
Assuming registration at the Registro de la Propiedad happens automatically once the escritura is signed — it requires a separate filing step and tax payment first.
Not budgeting time for the notary/registry sequence when a mortgage is involved, since deed signing and loan drawdown are simultaneous and both must be ready on the same date.
