The Spanish Supreme Court has definitively ruled that single-premium insurance fees tied to mortgage loans constitute an abusive practice, rendering such charges null and void.
The landmark decision, issued in ruling 913/2026 on June 11, clarifies that banks cannot enforce these upfront costs when they are bundled into the loan financing structure.
The judgment establishes a clear legal precedent for borrowers seeking restitution.
Under the court's interpretation, the statute of limitations for filing refund claims begins only after a borrower secures a favorable judicial ruling, rather than from the date the fee was originally paid.
This procedural clarification significantly extends the window for potential litigation against lenders.
For the Spanish banking sector, the ruling represents a material legal risk.
