Hello neighbors, some friends of mine have been house-hunting recently and are overwhelmed by all the paperwork. I remember being completely lost and making several mistakes when I bought my own place. So today, based on my personal experience, I’m going to break down the five key documents you absolutely, positively must ask the owner for when buying a resale property in Spain. Understanding these will help you avoid over 90% of the potential pitfalls!

1. The Property Registry Report (Nota Simple)
This is without a doubt the most important document, bar none! Think of it as the property’s ‘ID card.’ It’s issued by the Land Registry and clearly details the property’s official information. You must carefully check:
- Who the owner is: Is the person signing the contract the actual owner?
- Property description: Do the size, address, and other details match the actual property?
- Any outstanding debts: This is crucial! Check if the property is mortgaged to a bank or has been seized by a court. If so, these debts are tied to the property, and the new owner will be responsible for them!
2. The Energy Performance Certificate (Certificado de Eficiencia Energética - CEE)
This certificate has been mandatory since 2013. It rates the property’s energy consumption and CO2 emissions on a scale from A to G. While many overlook it, a low rating can mean your house will be cold in the winter and hot in the summer, leading to significant monthly electricity and gas bills. So, it’s wise to ask about the rating during a viewing to get a clear picture.
3. The Certificate of Occupancy (Cédula de Habitabilidad)
This document certifies that the property meets the minimum habitability standards set by the local government, making it a legal dwelling. This is especially crucial for older properties or those that have undergone illegal renovations, as they may not have this certificate, which is as fundamental as having proof of income for buying a house in Spain. Without it, not only is living there risky, but you’ll also face huge problems when trying to transfer utilities like water, electricity, and gas into your name. So, while you’re gathering your own documents like proof of income, don’t ever listen to an agent who says this isn’t important—insist on seeing the original!
4. Certificate of Paid Community Fees (Certificado de la Comunidad de Propietarios)
If you’re buying an apartment or a townhouse, you’ll almost certainly have community fees. This certificate, issued by the community president or administrator, proves that there are no outstanding community fees for the property. By law, the new owner is responsible for the current year’s fees and those of the previous three years. To avoid the awkward situation of paying off someone else’s debt right after buying, this certificate is essential.
5. The Latest Property Tax Receipt (Recibo del IBI)
The property tax (IBI) is an annual tax paid to the local city council. While the tax is associated with the owner, if the previous owner failed to pay it, the city council will pursue the debt against the property itself. Therefore, getting the latest IBI payment receipt serves two purposes: it confirms the tax is paid up, and it shows you the approximate annual holding cost for the property.
| Document Name | Main Purpose | Key Points |
| Nota Simple | Confirms ownership and debts | The most critical document, a must-check |
| CEE (Energy Performance Certificate) | Assesses property’s energy consumption | Impacts future living costs |
| Cédula de Habitabilidad (Certificate of Occupancy) | Certifies the property is legal to inhabit | Crucial for utility transfers (water, gas, electric) |
| Certificate of Paid Community Fees | Avoids inheriting community fee debts | Applies to apartments and community homes |
| Latest IBI Receipt | Confirms property tax is paid | Shows annual holding costs |
Buying a property in Spain is a major decision, especially for us foreigners, so we need to be extra cautious. Before you pay any deposit, make sure you get your hands on all five of these documents and review them carefully. It will save you countless headaches down the road.
