AML Record Keeping in Spain (10 Years)

Article 25 of Law 10/2010 requires you to keep due diligence and transaction records for ten years. It is the obligation that gets the least attention, and the one that turns any inspection into a problem when it has not been met.

What you must keep and for how long

Ten years, on a retrievable medium, with the ability to reconstruct the file as it stood.

Article 25 of Law 10/2010 requires obliged entities to keep, for a period of ten years, the documentation evidencing compliance with their due diligence obligations, as well as transaction documents and records. It is a long period, well above the one usually applied by default to ordinary business records.

What matters is not the period itself but what it implies: you do not comply by storing, you comply by being able to retrieve. An archive that exists but does not let you locate a specific customer’s file within a reasonable time, or that returns a document you cannot open because the format has become obsolete, does not satisfy Article 25, even if technically nothing has been lost.

And there is a second side that almost nobody works on: deletion. Keeping records beyond the legal period without justification is not prudence; it is processing data without a lawful basis. The retention policy has to say when records are kept and also when they are destroyed, with a record showing that they were destroyed.

Which documents the obligation covers

Six blocks, each with its own start-date rule and its own pitfalls.

Which records the retention obligation covers
BlockWhat it includesWhen the period startsCommon mistake
Customer identificationIdentity document, verification data, representation and powers of attorneyFrom the end of the business relationshipThe period is counted from onboarding instead of offboarding, which shortens the real period by several years.
Beneficial ownerOrganization charts, declarations, verifications and the reasoning behind the control-chain analysisFrom the end of the relationshipThe outcome is kept but not the reasoning, which is exactly what inspectors ask for.
Purpose and natureInformation on the customer’s business and the purpose of the relationshipFrom the end of the relationshipIt stays in a salesperson’s loose notes that never reach the file.
TransactionsDocuments and records evidencing each transactionFrom the execution of the transactionThe accounting entry is kept but not the supporting documents that justified it.
Analysis and alertsAlerts generated, analysis performed, conclusion and decision takenFrom the close of the analysisAlerts closed as false positives are deleted, and they are precisely the ones that show analysis took place.
ReportsReports filed with SEPBLAC and acknowledgments of receiptFrom filingThe acknowledgment is kept on its own, without the file that gave rise to it.

The start date is not the same for every block: due diligence records are tied to the end of the business relationship, and transaction records to the execution of the transaction. It is advisable to set this down in writing in the retention policy to avoid premature deletion.

AML record keeping vs. data protection

Two obligations that seem to conflict but in fact apply one after the other.

AML record keeping and data protection: how they coexist
IssueAML framework (Law 10/2010)GDPR frameworkHow it is resolved
Lawful basis for processingLegal obligation to keep recordsCompliance with a legal obligation (Art. 6(1)(c))The basis exists; it must be documented in the record of processing activities
PeriodTen yearsAs long as necessary for the purposeThe AML period sets the GDPR period; it does not go beyond it
PurposePreventing money laundering and responding to requests for informationLimited and explicitThe AML archive cannot be used for commercial purposes
AccessRestricted to those who need itData minimization and access controlSpecific permissions and an access log
Right to erasureGives way to the legal obligationCan be exercised, within limitsRefused, with reasons, during the period
When the period expiresThe obligation to keep records endsRequires erasure if there is no other basisDocumented deletion

The apparent conflict between the two frameworks is almost always resolved the same way: during the legal period, retention prevails; once the period has expired, erasure prevails. What cannot be defended is keeping records indefinitely “just in case”.

Where records get lost in each sector

The failure is rarely deliberate destruction: it is a migration, a change of provider or a format that dies.

Fintech

The platform migration

“The core system or the KYC provider changes, and the old files end up in a system nobody can access anymore.”

Law firms

The paper file

“There is still a physical archive, and the criteria for what was digitized and what was not were never documented.”

Real estate

The agent who left

“The customer’s records were in the email or on the computer of whoever handled the deal, not in a shared repository.”

Crypto

The monitoring history

“On-chain transactions are kept, but not the alerts or the analysis carried out on them.”

What happens if you cannot retrieve the records

Record keeping is the obligation that holds up all the others: without a document, there is no proof that anything was complied with.

Being unable to produce a file is worse than having an incomplete one. A file with gaps can be argued over; a file that does not turn up is treated as nonexistent.

The breach comes to light at the worst moment: when there is already a request for information on the table and only a few days to respond.

And keeping too much is not neutral either. Holding personal data without a lawful basis after the period has expired is a different problem, but it can also be sanctioned.

Penalties for breaching Law 10/2010 on AML/CFT in Spain
SeverityAmountBasis or alternative
Minor infringementsup to €60,000Less significant breaches, or breaches with no appreciable impact on the AML/CFT system.
Serious infringements€60,000 – €5,000,000Or 10% of the company’s total resources.

Try it: ask for a customer file from eight years ago

It is the quickest test there is to find out whether your AML archive works. If it takes more than a day or comes back incomplete, you have a problem worth fixing before the next inspection.

AML record keeping: common questions

How long must AML records be kept?

Ten years, under Article 25 of Law 10/2010. The start date is not the same for every block of records: due diligence records are tied to the end of the business relationship, and transaction records to the execution of the transaction.

Is a digital copy enough?

Yes, as long as integrity, legibility and retrievability are ensured for the whole period. What does not work is partial digitization without documented criteria, or a format that cannot be opened seven years from now. The retention policy must address storage medium, format and migrations.

When does the ten-year period start?

For due diligence records, from the end of the business relationship, not from onboarding. This is one of the most common calculation errors and the one that leads to premature deletion: a customer with a fifteen-year relationship means keeping their file until ten years after they leave.

Do alerts closed as false positives have to be kept?

Yes, and they are among the most valuable records. An alert closed with documented analysis shows that the monitoring system works and that judgment was applied. Deleting them leaves a record showing only the alerts that ended in a report, which suggests—wrongly—that nothing else is analyzed.

What about the GDPR? Don’t we have to erase the data?

During the legal retention period, the AML obligation serves as the lawful basis for processing and prevails over the right to erasure, which must be refused with reasons. Once the period has expired, the logic is reversed: if there is no other legal basis, the data must be erased. We cover this in detail on our data protection page.

What if an external provider holds the records?

The responsibility is still yours. The contract with the provider must guarantee retention for the legal period, access at any time and—critically—full return of the records when the relationship ends. If you outsource KYC or archiving, check that clause: it is the one most often missing. More on AML outsourcing.

Does deletion have to be documented?

It is strongly advisable. A retention policy that provides for deletion at expiry but leaves no record that it was carried out cannot explain why a file from twelve years ago is no longer there. The deletion record is what distinguishes compliant erasure from a loss of information.

What will they ask for in an inspection?

Usually a sample of specific files by name and date. What is assessed is not only whether they turn up, but how long it takes to locate them and whether they come complete with their context: identification, beneficial owner, purpose, transactions, alerts and decisions.

Does the AMLR change the period?

Regulation (EU) 2024/1624 also regulates the retention period, with a similar scheme, and harmonizes it at EU level from July 10, 2027. Before that date, it is advisable to review your internal policy to check that there are no differences in how the period is calculated. More on the AMLR page.

Can records be kept for more than ten years just in case?

Not without a basis that justifies it. Ongoing court proceedings, sanction proceedings or a pending claim may justify keeping specific records for longer. What does not hold up is indefinite, across-the-board retention as a default policy.

Practical guide to AML record keeping

A useful retention policy fits in a few pages and answers five questions: what, how long, where, who has access and when it is deleted. Ten steps to write it and test it.

Start date

Set the start date

For each block of records. Due diligence from when the customer leaves; transactions from their execution. Without this precision, deletions will be premature or late.

Retrieval

Test that it works

A policy nobody has tested is a hypothesis. Once a year, ask for two old files at random and time how long it takes.

Deletion

And close the loop

Define what is destroyed at expiry, who carries it out and how it is recorded. Documented deletion is part of compliance, not the opposite.

10-step AML record-keeping checklist

  1. Inventory the blocks of records subject to retention and where each one currently sits.
  2. Set down in writing the rule for calculating the period for each block, distinguishing due diligence from transactions.
  3. Define the storage medium and format, planning for technology migrations.
  4. Set access permissions for the archive and keep an access log.
  5. Regulate custody by contract when a provider holds the records, including their return.
  6. Draft the procedure for responding to requests for information: who locates the records, within what time frame and in what format they are delivered.
  7. Document the lawful basis for GDPR purposes and the policy for responding to erasure requests.
  8. Define the deletion procedure at expiry, with a person in charge and a record of execution.
  9. Run an annual retrieval test on old files chosen at random.
  10. Review the policy after each system migration, change of provider or relevant regulatory change.

If you want to test your archive before the supervisor does, start with an AML/CFT audit or the external expert report.

Record keeping in operation

From “it’s all on file” to being able to prove it

Record keeping breaks down at specific, predictable moments. These are the four.

Getting the document into the archive1) Capture

Getting the document into the archive

A file that lives in a salesperson’s email or in a local folder is not being kept: it is at risk of disappearing along with that person.

  • Single repository
  • No local copies
  • Capture within the workflow
Keeping it the same document2) Integrity

Keeping it the same document

Stable format, preserved metadata and a record of versions. A PDF regenerated without its context loses much of its evidential value.

  • Durable format
  • Metadata
  • Versioning
Surviving a system change3) Migration

Surviving a system change

This is when most records are lost. Every migration needs an explicit plan for historical records, not just for live data.

  • Plan for historical records
  • Post-migration check
  • Access to the old system

Quick map: do we keep this?

Three common questions and their answers.

Closed alert

Yes. It is the proof that analysis took place. Keep it with its conclusion and date.

Prospect who never became a customer

Yes, if due diligence was started. Keep what was collected.

File from eleven years ago

No, if the period has expired and no proceedings are open. And keep a record of the deletion.

  • Alerts closed as false positives are purged periodically.
  • A provider holds the records and there is no return clause.

The six record-keeping failures we see most

None of them is detected until a request for information arrives, which is exactly the problem.

Counting the period from onboarding

The period for due diligence records starts at the end of the relationship. Counting from onboarding leads to premature deletion of files that still had to be kept.

Purging closed alerts

Alerts that did not lead to a report are the proof that analysis exists. Without them, the record suggests that you only look at what gets reported.

Migrating without a plan for historical records

The migration project focuses on live data, and closed files are left in a system that nobody will be able to access two years later.

Outsourcing without a return clause

The provider holds the records and the contract does not say what happens when the relationship ends. When it does end, it is too late to negotiate.

Not documenting deletion

Records are correctly destroyed at expiry but no record of it is kept, and years later you cannot tell compliant erasure apart from a loss.

Never testing retrieval

The policy exists, the archive exists, and nobody has ever checked how long it takes to pull a file from eight years ago. It is an afternoon’s test.

Legal framework for AML/CFT record keeping

The record-keeping obligation is set out in Article 25 of Law 10/2010 of April 28 on the prevention of money laundering and terrorist financing. It requires obliged entities to keep, for ten years, the documentation evidencing compliance with their due diligence obligations, as well as the documents and records of the transactions carried out.

Keeping is not storing: it is being able to retrieve

Complying with Article 25 is not just a matter of the document existing, physically or electronically. It requires integrity (the document kept is the same one and remains legible), context (the file can be reconstructed as it stood at the time) and retrievability within a time frame compatible with responding to a request for information. An archive that keeps everything but takes weeks to locate a specific file does not meet the obligation in substance, even if nothing has been lost.

Calculating the period

This is where most errors are concentrated. Due diligence records are kept for ten years from the end of the business relationship, not from customer onboarding. Transaction records are tied to the execution of each transaction. Applying a single start date from onboarding leads to premature deletion of files that legally still had to be kept, and it is a recurring deficiency in external expert reports.

Coexistence with the GDPR

The legal retention obligation is a lawful basis for processing under Article 6(1)(c) of the General Data Protection Regulation, and during the legal period it allows erasure requests to be refused with reasons. Once the period has expired, the relationship is reversed: if there is no other legal basis, the data must be erased. Indefinite retention “just in case” has no support in either framework. You can see the full picture on our data protection page.

What changes with the AMLR

Regulation (EU) 2024/1624 (AMLR), applicable from July 10, 2027, also regulates the retention period for information obtained when applying due diligence measures, harmonizing it at EU level. For Spanish entities, the useful exercise before that date is to review the internal policy—especially the start-date rules and the deletion procedure—to identify differences and correct them in good time. This work fits naturally with the review of the AML manual and with the year’s external expert report.
