FEIN (Ficha Europea de Información Normalizada)

Document the bank must give the client at least ten calendar days before signing a mortgage, containing the personalised, binding offer: amount, term, interest rate, APR, instalment schedule, combined products, fees and early repayment costs. Binding means the bank cannot worsen those conditions afterwards. It comes with the FiAE, which summarises the most relevant clauses (reference index, early termination clauses, cost allocation). With both, the client visits the notary of their choice for a free prior deed in which the notary checks that they understand what they are signing; without that step the mortgage cannot be authorised. Its format is identical across Europe, designed to compare offers from different banks box by box.
