Are you considering investing in real estate in Spain – as a home, vacation home or commercial? The Spanish market is attractive, but also contains legal risks.
Here you get an overview of urban planning law (ordenación urbanística), construction law (contrato de obra) and important legal investigations.
1. Urban planning and local plans (PGOU)
Each Spanish municipality has a Plan General de Ordenación Urbana (PGOU), which establishes:
- Classification: urban (building plots), rural (land zone), developable (development area)
- Permitted use: residential, commercial, agriculture, etc.
- Build-up percentage, building height and distance requirements
A home can look finished – but still be illegally built. Therefore, a planning investigation with the municipality (Ayuntamiento) is always necessary.
2. Construction contracts and construction law
For new construction or renovation, you must enter into a construction contract (contrato de obra) with a local contractor.
The contract should include:
- Project description and technical appendices
- Schedule and deadline
- Price and payment plan
- Guarantees and liability insurance (e.g. decenal)
- Permits and responsibility for construction waste, etc.
- Clauses for delays or errors
Avoid signing a standard contract without legal review – it's your best defense against disputes.
3. Legal due diligence before purchase
Before you buy, a thorough legal due diligence should be performed:
- Property rights and encumbrances: ownership, mortgage encumbrances and easements
- Urban status: building permits, legalization, requirements from the municipality
- Occupancy certificate and energy rating – required for occupancy and resale
- Tax matters: calculation of transfer tax, notary fees, registration
- Community: for condominiums, bylaws and finances must be examined
The purpose is to uncover hidden legal and economic risks, which can otherwise become expensive.
4. Deed and registration
When the agreement is signed and the purchase price is paid, the property must be transferred via notary:
- Signing of escritura pública (deed)
- Payment of taxes and registration fee
- Official registration in Property Registry
- Application for NIE and opening of bank account
The entire process should be handled by a lawyer – to ensure correct ownership without delays.
5. Conclusion: Get organized with the law before you invest
Real estate in Spain can be a solid investment – if handled correctly. Therefore, you should always:
- Investigate local plan and building permits
- Have a written and reviewed construction contract
- Have legal due diligence performed before purchase
