A new law obliges real estate agencies in Spain to list all costs upfront. Buyers must be informed of every expense from the first advertisement. Failure to comply allows legal claims against agencies.
Spain has introduced a legal requirement that changes how real estate agencies must present property listings. Under the recently enacted Ley 10/2025, agencies are now obligated to disclose every cost associated with purchasing a home directly in the initial advertisement. This measure aims to prevent buyers from facing unexpected charges after showing interest in a property, a problem that has affected many, especially younger buyers struggling to enter the housing market.
Economist José María Páez has drawn attention to the new rule, emphasizing that agencies can no longer wait until a property visit or contract signing to reveal the full financial picture. According to Páez, the law makes it clear that all expenses—whether taxes, agency fees, or additional charges—must be visible from the outset. If an agency fails to comply, buyers have the right to challenge any subsequent payments that were not included in the original listing.
The change responds to a widespread issue in Spain, where buyers often discover that the advertised price does not reflect the total amount required to complete a purchase. Many have found themselves facing extra costs only after committing to a deal, leading to disputes and, in some cases, legal action. The new regulation seeks to close this gap by making the advertisement itself a binding part of the contract, not just a marketing tool.
Páez, who has used social media to inform the public, notes that most property ads still do not comply with the updated law. He advises potential buyers to keep records of original listings and to seek legal advice if they encounter undisclosed charges. The law, in force since December 2025, gives buyers a stronger position to contest any fees that were not transparently communicated from the beginning.
Legal experts recommend that anyone affected by hidden costs should consider formal complaints, as the law now supports such claims. The fine print in contracts and any clarifications made after the initial ad can be grounds for a legal challenge if they introduce new expenses. This shift is expected to increase transparency in the Spanish property market and reduce the risk of disputes between buyers and agencies.
The issue of housing affordability and transparency has been a recurring topic in Spain. In Catalonia, for example, authorities have moved to restrict speculative purchases in high-demand areas, aiming to protect residents from being priced out by large investors.

Spain's housing market has faced mounting pressure in recent years, with rising prices and limited supply making it difficult for many to buy a home. The new legal requirement for full cost disclosure is part of a broader push to improve consumer protection and restore trust in real estate transactions. As the law takes effect, both buyers and agencies will need to adapt to stricter standards of transparency and accountability.
For context, Spain's property sector has long been criticized for opaque pricing and complex fee structures. The introduction of Ley 10/2025 marks a significant step toward aligning Spanish practices with broader European standards, where consumer rights in real estate are more robustly protected. The effectiveness of the new rule will depend on enforcement and the willingness of buyers to assert their rights when agencies fall short of the law's requirements.
