Legal Checklist Before Buying a Property in Spain (2026)

Buying a home in Spain is a wonderful thing to do, but the moment you move from browsing listings to making an offer, a clear legal checklist before buying a property in Spain is what stands between a smooth purchase and an expensive mistake. On Mallorca, where a large share of buyers are non-residents purchasing from abroad, the distance between the Spanish system and the one you know at home is exactly where problems tend to appear. This article sets out the legal checks that matter before you commit, and shows you where each one quietly goes wrong.

In this article you will find: how the Spanish buying process differs from what you may expect, the checks to run on the property itself, the paperwork you need in place, what happens at the deposit and signing stages, and the questions buyers ask us most often.

Why buying in Spain is not like buying back home

Many buyers arrive expecting the process they know from the UK, Ireland, or the US. Spain works differently, and assuming otherwise is one of the most common reasons a purchase runs into trouble. If you are right at the start of your search, our complete guide to Buying Property in Mallorca as a Foreigner sets the scene, and this checklist zooms in on the legal checks within it.

Due diligence is on you, not the system

In Spain there is no automatic set of searches carried out on your behalf. No one is obliged to tell you that the property carries a debt, that an extension was built without a licence, or that a boundary does not match the deed. If you do not check, or have someone check for you, the issue becomes yours on the day you sign.

The people you will meet, and who actually protects you

Three roles come up again and again, and they are not interchangeable. Knowing the difference early saves a lot of confusion later.

The notary is not there to look after your side of the deal, which surprises many first-time buyers. Whether you need your own lawyer is a question we answer in full separately.

The legal checklist before buying a property: the property itself

Before you fall for the terrace and the sea view, the property has to pass a set of basic legal checks. This is the heart of the legal checklist before buying a property in Spain.

Confirm who owns it, and what comes with it

The nota simple is the extract from the Land Registry that shows the registered owner, the description of the property, and any charges against it. Ask for a recent one and confirm:

• The seller is the registered owner, or is legally entitled to sell.
• The description and size match what you are actually buying.
• There are no mortgages, embargoes, or liens left on the title.

You can request a nota simple through the Spanish Land Registry, and reading it correctly is where a trained eye earns its keep.

Debts, community fees, and arrears

In Spain, some debts travel with the property rather than the person. A buyer can inherit unpaid community fees or certain local taxes. Before committing, confirm:

• Community of owners fees are paid up to date, with a certificate from the administrator.
• Local property tax (IBI) is current.
• Utility accounts are settled and transferable.

Licences and the built reality

What exists on the ground does not always match what is on paper. Extensions, pools, and rural buildings are frequent culprits. A property with an unlicensed build can be hard to insure, to mortgage, or to sell on later. Where a home sits on rustic land or shows signs of later additions, this needs proper review before you proceed.

Getting your paperwork in order

Alongside the property, you need your own documents ready. For non-residents buying from abroad, this stage often takes longer than expected, so start early.

• Your NIE: The foreigner identification number is required to complete any purchase. Without it, the notary cannot proceed. We explain how it works in Why You Need an NIE Number to Buy Property in Spain.
• A Spanish bank account: Useful for transfers, for direct debits on utilities, and for the banker's cheque often used at completion.
• Proof of funds and clean transfers: Spanish banks and notaries apply anti-money-laundering checks, so keep clear records of where your money comes from.

The currency question for overseas buyers

If your funds sit in pounds or another currency, the exchange rate can move the real price of your home between the offer and completion. Many buyers use a specialist currency service rather than a high-street bank. This is a financial decision rather than a legal one, but it belongs on your checklist.

Buying from abroad: power of attorney

Most of our buyers are not on the island for the signing, and they do not need to be. A power of attorney lets a lawyer act for you, and it is one of the most useful tools available to an overseas buyer.

How it works

You grant a power of attorney to a lawyer you trust, who can then sign on your behalf at each stage, from the deposit contract through to the escritura before the notary. You follow the purchase from home and step in only where you choose to. For a buyer living in another country, it removes the need to fly over for every appointment.

Getting it right

A power of attorney is only as good as its wording, so a few points matter:

• The document should set out precisely what the lawyer can and cannot do.
• A power drawn too broadly hands over more control than you need.
• If you sign it outside Spain, for example before a notary at home, it will usually need an apostille and a sworn translation.

Used well, it is a safeguard and a convenience at once. Acting for clients this way is central to what we do, and we set the power up so it stays firmly within your control.

The deposit stage: where money gets committed

This is the point where buyers part with real money, often before they have taken proper advice. It is also where the most painful losses happen.

Reservation and deposit agreements

A small reservation payment usually takes the property off the market. The larger commitment comes with the deposit contract, and its terms decide what happens if either side pulls out.

The arras contract and its risks

The most common deposit contract in Spain is the contrato de arras. Signed carelessly, it can cost you the full deposit if you cannot complete, or leave you under-protected if the seller walks away. Because the wording carries real consequences, we cover it on its own.

Costs, taxes, and completion

Two final areas round out the checklist: what you will pay, and what happens on the day.

Budget beyond the asking price

The purchase price is not the full cost. On top of it, buyers should plan for items such as:

• Transfer tax or VAT, depending on whether the home is a resale or a new build.
• Notary and Land Registry fees.
• Legal and administrative fees.

The exact figures for the Balearic Islands deserve their own treatment, which is why we set them out fully in a dedicated article rather than summarise them loosely here.

Signing the escritura, and what comes after

Completion takes place before a notary, where the public deed, the escritura, is signed and the balance paid. Non-resident sellers face a retention on the price for tax, and buyers should understand exactly what they are signing before they sign it. After signing, the deed is registered and the utilities move into your name.

Frequently asked questions

Do I need a Spanish lawyer to buy a property in Spain?

You are not legally required to, but because no one else in the transaction represents your interests, most non-resident buyers instruct an independent lawyer. Our guide, Do I Need a Lawyer to Buy Property in Spain?, explains what a lawyer does that the notary does not.

Can I buy property in Spain as a non-resident?

Yes. Non-residents buy freely in Spain. You will need an NIE, and some tax treatment differs from residents, but ownership itself is open to you.

What is the arras contract?

It is the private deposit contract signed before completion. It sets out the price, the deadline, and what happens if either party fails to complete. The type of arras used changes your rights significantly.

How long does the buying process take?

With paperwork in order, a simple purchase often completes within four to eight weeks. Delays usually come from a missing NIE, from financing, or from issues found during the checks.
