What is FEIN in Spain?

3/31/2026

European Standardised Information Sheet (ESIS)

It is simply a standardised mortgage credit form in accordance with the EU directive, the aim of which is to make it easier to compare offers on the market.

What is the FEIN in the context of mortgage loans?

The FEIN is a document required by European Union legislation (Directive 2014/17/EU) and by Spanish mortgage regulations. Banks must provide this document to the customer before the credit agreement is signed. Its purpose is:

  • To set out the terms of the loan.
  • To enable the customer to compare offers from different banks, if available.
  • Protect consumers against unclear terms or financial risks.

Contents of the FEIN document

The FEIN contains detailed information about the loan offered, such as:

  1. Loan amount and currency.
  2. Interest rate: fixed or variable, including details of the reference rate (e.g. EURIBOR).
  3. Total cost of the loan: APR (Annual Percentage Rate), which includes all fees and charges.
  4. Monthly repayment and information on changes to the repayment amount in the case of variable-rate loans.
  5. Loan term.
  6. Repayment terms and any fees for early repayment.
  7. Potential risks associated with foreign currency loans, where applicable.

Importance of the FEIN for the borrower

  • Time for review: The borrower has a minimum of 10 working days to review the document before signing the loan agreement.
  • Comparison of offers: It allows for easy comparison of the terms offered by different banks.
  • Informed decisions: The FEIN contains all the financial details, so the customer knows exactly what they are committing to.

The bank’s obligation

In Spain, the FEIN also confirms the terms of the mortgage loan applied for by the customer. This document is simply a summary of the loan terms.

Spanish banks are legally obliged to provide the FEIN to every customer during the mortgage application process. This document forms part of the standard lending process and cannot be omitted.

Thanks to the FEIN, the borrower can make a fully informed decision, reducing the risk of misunderstandings and unexpected costs.

The form may bear some resemblance to the Polish mortgage loan form, but it is somewhat more extensive than that.
