| New build | Off-plan purchases require extra checks. | Licence, bank guarantee, payment plan, handover and snagging. |

Essential Legal Verification Steps and Costs
Professional due diligence on Costa del Sol property begins with appointing an independent Spanish property lawyer, typically costing 1.5–2.5% of the purchase price including notary and Land Registry fees. Your lawyer will conduct a comprehensive Land Registry (Registro de la Propiedad) search at €9–15 per certificate to verify ownership, identify mortgages, liens, or embargos, and confirm the property description matches reality. Simultaneously, they'll check the Municipal Cadastre at €3–8 per search to verify tax values and physical boundaries.
Critical planning verification involves requesting the property's planning history from the local Ayuntamiento, including the essential Licencia de Primera Ocupación (First Occupancy License) and building permits. This step costs approximately €50–150 in municipal fees but prevents potentially catastrophic issues. Your lawyer will also obtain an updated IBI certificate showing annual council tax obligations of 0.4–1.1% of cadastral value and verify all community fees are current, as unpaid debts transfer automatically to new owners under Spanish law.
Financial and Debt Investigation Requirements
A thorough financial audit reveals all outstanding obligations that could transfer to you as the new owner. This includes verification of current IBI payments (typically €500–3,000 annually depending on property value), community fees ranging €50–200 monthly for apartments, and utility debts. Your lawyer will request certificates of debt-free status from electricity, water, and gas suppliers, each costing €15–25 to obtain.
For properties generating rental income, investigation must include verification of existing tenancy agreements and deposits held. Under Spanish law, sitting tenants' rights transfer to new owners, making this crucial for investment properties. Your lawyer will also verify the property's tax status, ensuring it's registered correctly for IBI purposes and identifying any outstanding fines or municipal charges that could reach thousands of euros in accumulated debt.
Costa del Sol Specific Risks and Protections
The Costa del Sol's complex planning history requires additional scrutiny beyond standard due diligence. Over 300,000 properties in Andalucía have some form of planning irregularity, with potential demolition costs exceeding €50,000 per property. Your lawyer must verify the property appears on the PGOU (Plan General de Ordenación Urbana) and holds valid planning permissions, particularly for properties built between 1960–2010 when enforcement was inconsistent.
Coastal properties require additional checks for DPMT (Dominio Público Marítimo-Terrestre) compliance, ensuring buildings maintain required distances from the shoreline. Violations can result in demolition orders with no compensation. Properties in flood zones or areas with geological instability need environmental surveys costing €800–1,500 but potentially saving tens of thousands in future remediation costs. Your lawyer should also verify the property isn't subject to any planned infrastructure developments that could affect value or habitability.
Next Steps and Professional Support
Begin due diligence immediately after agreeing terms but before signing any binding contracts. Allow 4–6 weeks for comprehensive investigation, particularly for rural properties or those with complex histories. Your lawyer should provide a detailed written report covering all findings, with clear recommendations about proceeding or renegotiating terms based on discoveries.
Consider engaging independent structural surveyors (€400–800) for older properties and ensure your lawyer has experience with your specific municipality's procedures, as requirements vary significantly between Marbella, Fuengirola, Estepona, and smaller coastal towns.
