Mortgage Transparency Act: A Guide for Buyers
If you’re in the process of buying a home and you’re going to apply for a loan, you’ve probably heard about the transparency deed. This document, created under the Law on Real Estate Credit Contracts (LCCI), is the most important safety filter so that the consumer understands exactly what they are signing before committing to the bank.
In this article, we explain in a straightforward way everything you need to know to make your notary appointment a success.
What is the prior transparency deed?
The transparency deed is a mandatory notarial document signed days before the mortgage deed is executed. Its purpose is to ensure that the client has received all the necessary information from the bank and that fully understands the contract clauses, especially the more complex ones such as interest rates, fees, or linked products.
The Notary’s role: Your independent advisor
Unlike signing the mortgage, where the bank and the buyer are both present, at the transparency deed it’s only you (the borrower) and the notary.
The notary’s job is to:
Verify that the bank has provided you with the documentation within the legally required timeframe.
Explain each point of the contract in an impartial manner.
Administer a comprehension test to make sure you have no doubts about what you are going to sign.
Documents you should know: FEIN and FIAE
For the transparency deed to be valid, the bank must have given you the following in advance:
FEIN (European Standardised Information Sheet): The binding offer with all the loan’s terms and conditions.
FIAE (Standardised Warning Information Sheet): Where the most sensitive clauses are laid out in detail (fees, variable interest rate, limits on interest, etc.).
A copy of the contract and a breakdown of costs.
Legal timelines: When does it need to be signed?
The law is very strict about timing to protect consumers from rushing:
In Spain in general and in Extremadura in particular: The deed must be signed, at minimum, 10 calendar days before the mortgage deed is signed.
In Catalonia: The deadline is extended to 14 calendar days.
During this reflection period, you can review the information and, if you’re not comfortable with something, you can back out without penalties.
How much does the transparency deed cost?
It’s important that you know that the transparency deed is free of charge for the client. The notary fees arising from this prior advice are entirely covered by the banking institution. You simply choose the notary you trust.
In short
The transparency deed isn’t just a bureaucratic formality; it’s your protection shield as a consumer. Thanks to it, unpleasant surprises are avoided in the future and it’s guaranteed that your mortgage is transparent, legal, and fair.
Frequently Asked Questions about the Transparency Deed
Is it mandatory to sign the transparency deed?
Yes, it’s an essential legal requirement under the 2019 Law on Real Estate Credit Contracts. Without this notarised deed signed before a notary, it’s not possible to proceed with the signing of the mortgage deed.
How much does this procedure cost the buyer?
The transparency deed is completely free of charge for the client. The notary costs for this prior step are assumed by the banking institution by law.
Can I choose the notary myself, or does the bank choose?
As a consumer, you have the legal right to choose the notary you prefer. The bank can’t impose a specific notary for this procedure or for the mortgage deed signing.
Do I have to go with someone from the bank?
No. In fact, the bank shouldn’t be present. The goal is for the notary to advise you in a neutral and independent way to ensure there’s no pressure and that you understand all the clauses. You can go alone or with someone you trust who has no interest in the transaction.
What happens if I don’t pass the Notary’s “comprehension test”?
If the notary believes you don’t understand any essential point of the mortgage, they will not authorise the deed. In that case, you’ll need to ask the bank for further clarification and arrange a new appointment once your questions have been resolved. It’s a protective measure to ensure you don’t sign something harmful out of lack of knowledge.
How much time must pass between the deed and the mortgage deed signing?
As a general rule in Spain, at least 10 calendar days must pass from the moment the bank delivers the documentation to you until you sign the mortgage. The deed must be signed within that safety period (normally a couple of days before the final signing). In Catalonia, this deadline is extended to 14 days.
What documents should I bring to the notary appointment?
You must bring your original, valid DNI or NIE. The notary will already have the documentation that the bank uploaded in advance to the electronic platform (FEIN, FIAE, etc.), so all you need to do is attend to receive the advice and sign.
