Why Does This Matter?
Spanish banks are required, under the anti-money-laundering and counter-terrorist-financing law (Ley de Prevención de Blanqueo de Capitales), to review the origin of clients' funds. Because Iran is on the list of high-risk countries due to international sanctions, banks apply an "enhanced due diligence" (Diligencia Reforzada) review level for clients with an Iranian connection — whether an Iranian citizen or a transaction with an Iranian origin.
Failing to provide sufficient documentation, or ambiguity in explaining the origin of funds, can lead to a temporary or even permanent freeze of the bank account. Transparency from the start of the process is the best form of prevention.
Documents Accepted to Prove the Origin of Funds
- An official property sale deed (Escritura de Compraventa), with an official translation and an apostille if required
- Payslips or an employment contract from recent years
- Official tax returns from recent years
- An official inheritance deed (Escritura de Herencia) if the source of funds is an inheritance
- Ongoing bank statements showing the pathway of fund accumulation
The Bank's Review Process
| Step | Description |
|---|---|
| Client identification (KYC) | Identity verification and an initial review of the client's financial history |
| Enhanced due diligence | Requesting supplementary documents for clients connected to high-risk countries |
| Reviewing the transaction pathway | Tracing the transfer of funds from source to the destination account in Spain |
| Approval or rejection | The bank's final decision on accepting the transaction or opening the account |
Most banks only accept documents issued in Iran together with an official translation into Spanish and, in some cases, consular certification or an apostille. Preparing these documents before approaching the bank shortens processing time.
Recommendations to Avoid an Account Freeze
- Prepare complete documentation on the origin of funds before transferring large amounts
- Avoid scattered or unexplainable transactions
- Respond as quickly as possible if the bank requests additional explanations
- If there is ambiguity or the request is rejected, seek specialised legal advice before repeating the transaction
