IRPH Claim in Spain: How to Challenge an IRPH Mortgage

Thousands of mortgage borrowers in Spain may have paid significantly more interest because their loan was linked to the IRPH index instead of Euribor.

Following several rulings by the Court of Justice of the European Union, Spanish courts must analyse whether IRPH clauses were transparent and properly explained.

If the bank failed to provide sufficient information about how the index works, borrowers may be able to challenge the clause and recover overpaid interest.

For a practical explanation of how the latest European court reasoning affects IRPH mortgage claims in Spain, read our guide on the EU ruling on IRPH mortgages in Spain.

What Is an IRPH Claim?

An IRPH claim is a legal action filed by a borrower to challenge the validity of the IRPH clause in a mortgage contract

Can borrowers challenge IRPH mortgages?

Borrowers may challenge an IRPH mortgage clause if the bank did not clearly explain how the IRPH index works or the financial consequences of using it.

Spanish courts analyse whether the borrower received sufficient information to understand the cost difference between IRPH and other reference indexes such as Euribor..

The claim usually argues that the clause is abusive because the borrower was not given enough information to understand the financial consequences of using IRPH instead of Euribor.

Courts evaluate whether the bank complied with transparency requirements under European consumer protection law.

When Can an IRPH Claim Be Filed?

An IRPH claim may be possible when the borrower was not properly informed about:

• how IRPH is calculated
• how IRPH compares with Euribor
• the financial impact of choosing IRPH

If the bank did not clearly explain these aspects before the mortgage was signed, the clause may be declared abusive.

What Happens If the Court Rules in Favour of the Borrower?

If the court determines that the IRPH clause was not transparent, several outcomes are possible.

The court may:

• remove the IRPH index from the mortgage
• replace it with another reference rate
• recalculate the interest paid
• order the bank to refund overpaid interest

Many successful IRPH claims result in borrowers recovering significant amounts of money.

What Documents Are Needed for an IRPH Claim?

To analyse whether an IRPH claim is possible, the following documents are usually required:

• the mortgage deed
• mortgage payment history
• bank documentation related to the loan

The mortgage deed is particularly important because it shows how the IRPH clause was presented in the contract.

How Long Does an IRPH Claim Take?

The duration of an IRPH claim depends on the court handling the case and the complexity of the legal analysis.

In many cases, claims take between one and two years.

However, each case is different and timelines may vary.

Borrowers who believe their mortgage used the IRPH index often want to estimate the financial impact before filing a claim.
