Legal Formalities When Buying a Home in Spain: How to Avoid Mistakes

Buying a home in Spain is not only a dream come true but also a legal transaction that must be handled with the utmost care. From the first contact to signing at the notary (notario), every step has legal, tax and administrative consequences that should not be underestimated. Whether you are looking for a first home, a second property or an investment, knowing the legal formalities will help you make more confident decisions and avoid problems down the line.

Did you know that many buyers do not check whether a property has encumbrances in the land registry or whether the seller is genuinely the legal owner? Others do not distinguish between the notarial escritura pública (public deed) and the arras contract (a preliminary contract with a deposit), or do not understand when taxes such as ITP or IVA have to be paid. Quite often they also don't know how to estimate notary costs, or what the buyer is obliged to do before signing. That is why we have prepared this guide: to help you understand the logical sequence of formalities, the mandatory documents and the most common mistakes that can be avoided.

If you are thinking of investing in areas such as Alicante or Finestrat, our property buying guide, the description of the buying process with Kornilenko and the overview of the most exclusive areas to live in will show you how to do it safely and with competent support. A safe purchase starts with being well informed. And you are just about to be.

Before Signing: The Key Documents

Before signing a contract or paying a deposit, you need to know the legal status of the property thoroughly. The first mandatory step is to request a Nota Simple Registral (an extract from the land registry) from the Registro de la Propiedad. This document tells you who the legal owner of the property is, as well as any existing encumbrances, mortgages, easements or seizures. Checking this information protects you from illegal or fraudulent transactions.

If you are considering a new-build home, you must not skip the licencia de primera ocupación (first occupation licence) and the cédula de habitabilidad (certificate of habitability), which confirm that the property complies with technical and urban planning regulations. These checks are an important part of the process, which we describe in the guide to the buying process with Kornilenko. And if it is a resale property, make sure the seller will give you:

• up-to-date receipts for payment of IBI (the property tax);
• a valid energy efficiency certificate;
• a document confirming that there is no debt owed to the homeowners' community.

All of these items belong to the legal formalities that precede a purchase and cannot be skipped if you want to avoid complications. You can also read our guide to legal costs to understand how each of these documents may affect the final price. A reliable purchase starts with checking the essentials, and with a sensible approach to that check.

Signing at the Notary and Registration

Once all the preliminary documentation has been gathered and checked, one of the most decisive moments arrives: signing the escritura pública at the notary. This legal act not only formalises the sale but also publicly records that the transaction was carried out in accordance with the law. The notary will check all the documents, confirm the identity of the parties and set out in detail the price, the form of payment and any existing encumbrances on the property. If everything is in order, the final signing takes place.

But the process does not end there. After signing, you will need to pay taxes, depending on the type of property. For resale properties, ITP (Impuesto de Transmisiones Patrimoniales, the property transfer tax) applies; for new builds, it is 10% IVA (VAT) plus approximately 1.5% AJD (Actos Jurídicos Documentados, the stamp duty on legally documented acts). All these costs are set out in our guide to legal costs, which will help you draw up a budget without unpleasant surprises.

Finally comes the key step: registering the sale at the Registro de la Propiedad. Only in this way will you obtain full legal protection as the new owner. If you want to see the whole path step by step, turn to our guide to the buying process with Kornilenko or to the general buying guide. Because once everything is properly registered, all that is left is to live in peace.

Buy Wisely, Live Peacefully

Buying a home is not just a transaction but an emotional and strategic decision. You want a home, of course, but you also need guarantees. The key is a balance between heart and head: letting yourself fall for a place while protecting your investment with reliable information. This is exactly where it matters to choose the right developer and to understand the whole process.

In our guide to choosing the ideal developer we explain how to recognise a serious, transparent company with a long-term vision. What matters is not only that the company builds well but also that it supports you legally from day one, as we do in our buying process, step by step. Because buying wisely does not mean doubting: it means gathering information, asking questions, comparing... and deciding with confidence.
