Completion day in Spain — la firma — is the moment your property purchase becomes legally yours. It happens in a single meeting at a notary's office (notaría), usually lasting 30 to 60 minutes, where you and the seller sign the escritura pública de compraventa (the public title deed), you hand over the balance of the money, and the seller hands you the keys. From that signature the property is legally transferred, even before it reaches the Land Registry.
For buyers on the Costa Blanca, Costa Cálida, Costa del Sol and Costa Almería, the process is identical in law but the taxes triggered by that signature differ by region — and, importantly, on the Costa Blanca the date you sign the escritura now decides your tax rate (more on that below). This guide walks you through exactly what happens on the day, what the notary does, what it costs, and what changes once the deed reaches the registry.
A Spanish notario is a public official appointed by the state, not a lawyer working for either party. Their job is to be strictly neutral: to verify identities, confirm the parties have legal capacity, read the deed aloud, witness the signatures and give the document fe pública — public faith. The notary's authorisation turns a private contract into a public deed that can be registered.
Crucially, the notary does not represent your interests or check whether the purchase is a good idea. They will confirm from the Land Registry that the seller owns the property and flag any registered charges, but they will not chase unregistered debts, check community-fee arrears or negotiate on your behalf. That is your lawyer's job — which is exactly why an independent real estate lawyer matters as much as the notary.
By the time you reach the notary, most of the work is already done. A typical timeline from offer to signing looks like this:
The buyer normally has the right to choose the notary. In practice the estate agent or lawyer arranges an appointment at a local notaría near the property, in Alicante, Torrevieja, Murcia, Marbella, Málaga or Almería.
Everyone gathers at the notary's office: buyer, seller, both lawyers or representatives, the estate agent, and — if there is a mortgage — a representative of the bank. If you cannot attend in person, you can grant a power of attorney (poder) so your lawyer signs for you; this is extremely common for overseas buyers.
The sequence is roughly as follows:
You leave with a copia simple (an unofficial copy) the same day. The notarised original (copia autorizada) is prepared shortly after and used for registration.
The notary electronically notifies the Land Registry of the sale within hours of signing — this creates a priority entry (asiento de presentación) that blocks any competing claim for around 10 working days. This is a strong protection: even though full registration takes weeks, your position is secured from the moment of signing.
Your lawyer or gestoría then handles the paperwork that turns the deed into a fully registered title:
Full registration typically takes two to six weeks depending on the local registry's workload. The registry title in your name is your ultimate proof of ownership.
The largest cost is always the transfer tax, and this is where the four coasts diverge. The tax base is the higher of the purchase price or the cadastral valor de referencia — a point most competitor articles skip. If the reference value is higher than what you paid, you are taxed on the reference value, so ask your lawyer to check it before you agree a price.

*Costa Blanca ITP is 9% for deeds signed from 1 June 2026 (Ley 5/2025, reduced from 10%), with an 11% band on the portion above €1 million. Because the notary's signing date decides the rate — not the arras date — timing your completion can genuinely save money on a Costa Blanca purchase. Note the Costa Cálida figure too: many websites still quote the old 8% for Murcia, but the correct 2026 rate is 7.75% (Ley 3/2025).
For new builds, budget nearer the top of the range because IVA plus AJD together often exceed resale ITP. Our complete guide to buying taxes breaks down every line, and if you are weighing new against second-hand, see off-plan vs resale on the Costa Blanca.
By default the Spanish Civil Code splits notary costs (buyer pays the copies, seller pays the original), but in practice on the costas the buyer almost always pays all notary and registry fees unless negotiated otherwise. The seller pays the plusvalía municipal and capital gains tax. Make sure the split is written into your arras contract so there are no surprises at the notary desk.
For a brand-new property the developer must show the notary the Licencia de Primera Ocupación (first occupation licence) and the Certificado Final de Obra. Without these the property cannot legally be occupied or connected to utilities. Complete your snagging inspection before completion so any defects are documented while you still have leverage over the developer.
No. You can grant a power of attorney (poder) to your lawyer, signed at a Spanish notary or at a Spanish consulate abroad. This is very common for overseas buyers who cannot travel to the Costa Blanca, Cálida, del Sol or Almería for completion day.
The signing itself is usually 30 to 60 minutes. Full registration of the deed in your name at the Land Registry then takes a further two to six weeks, but you are the legal owner from the moment you sign.
No. Payment is made by bank-guaranteed cheque or verified bank transfer, and all funds must be traceable and declared under Spain's anti-money-laundering and cash-limit rules. The notary records the exact payment method in the deed.
Yes. The notary verifies the deed and identities but does not protect your interests, chase unregistered debts or check community arrears. An independent lawyer carries out the due diligence the notary will not.
Because in the Valencian Community the transfer tax rate depends on the date the escritura is signed at the notary. For deeds signed from 1 June 2026 the rate is 9% instead of 10%, so timing completion around that date can reduce your tax bill.
It is a cadastral reference value assigned to every property. Transfer tax is charged on the higher of your purchase price or this reference value, so if the reference value exceeds what you paid, you are taxed on the higher figure. Always check it before agreeing a price.
