Due Diligence When Buying Property in Spain
The legal checks your lawyer carries out on a Spanish property before you pay any deposit: ownership, charges, licences and debts.
Choose what you need
Due diligence is the set of legal checks your lawyer carries out on a Spanish property before you pay any deposit. It tells you who owns the property, whether it carries debts or charges, and whether what you see was built legally. Tomas Ballestero Lawyers does these checks for international buyers, from our office in Jávea and our associated office in Dénia, on the Costa Blanca.
The checksWhat we check
- Ownership and chargesThe nota simple from the Land Registry: the registered owner and any mortgages, embargoes or other charges.
- CatastroThe Catastro compared with the deed and with what is actually built.
- LicencesThe building licences, the occupation licence and any planning infringements at the town hall.
- DebtsIBI, the rubbish collection tax and community fees, some of which can follow the property to the new owner.
- The communityThe community rules, any planned works and the minutes of recent meetings.
- Special casesRustic land, the coastal law, tourist letting and, on a new build, the guarantees for each payment.

WhenBefore the deposit
The checks are done before the contrato de arras is signed. With arras penitenciales, a buyer who withdraws loses the deposit and a seller who withdraws returns it doubled, so finding a problem afterwards is costly. An updated nota simple is requested again just before completion.
The state of the building, the boundaries and the measurements are a technical matter. For a villa we always advise an inspection by an architect. We can put you in touch with Sergio Tomás Arquitectos in Jávea, an architect we usually work with, or you can instruct one of your own choice.
Frequently asked questions
Can debts of the seller pass to me?
Some can, such as unpaid IBI or community fees for a limited period. That is why we check them and arrange for them to be paid at completion.
Do I have to come to Spain?
No. Apart from the NIE, which is applied for in person, the whole purchase can be done by power of attorney.
