Report the fraud to the Police Grand-Ducale immediately at a police station or, in some cases, online. A criminal complaint may also be filed directly with the Public Prosecutor’s Office (Parquet / Ministère public). Provide all available evidence: contracts, payment records, communications, transaction references, and identity information for the counterparty.
If the fraud involves an investment firm, CASP, forex platform, bank, or other supervised financial-sector professional, file a complaint with the CSSF. For individual customer complaints, a prior complaint to the firm is required. The CSSF also accepts general complaints denouncing breaches of financial laws and regulations. CSSF complaints may be filed in English, French, German, or Luxembourgish.
Contact your bank or payment provider immediately to block compromised accounts, cards, and payments and initiate recall or chargeback procedures for fraudulent transactions.
Check the counterparty’s registration, business permit status, and any bankruptcy filings through Luxembourg’s official registers and Guichet. Bankruptcy or dissolution entries inform the enforcement strategy and determine whether asset preservation measures are necessary before civil proceedings.
Save all communications, contracts, invoices, payment confirmations, website screenshots, email headers, and transaction records without alteration. Digital evidence is critical for both criminal investigation and civil proceedings and may become inaccessible if platforms delete accounts or the counterparty destroys records. Evidence preservation should begin immediately upon discovery of the fraud.
Criminal complaints filed with the Police Grand-Ducale or directly with the Public Prosecutor’s Office initiate formal investigation under Luxembourg criminal law. Relevant offences include fraud (escroquerie), computer fraud, document fraud, identity fraud, money laundering, and fraudulent bankruptcy. Criminal proceedings provide access to investigative tools unavailable in civil litigation – bank record production orders, platform identity disclosure, telecommunications data, and international judicial cooperation through mutual legal assistance treaties and EU instruments.
Civil proceedings before the Tribunal d’arrondissement (District Court) are available for contractual claims, damages, restitution, unjust enrichment, and rescission of fraudulent transactions. The District Court contains civil, commercial, and criminal chambers. Freezing measures and interim relief can be obtained to prevent dissipation of assets during proceedings. Civil litigation targets the fraudster and, where applicable, institutions that failed to prevent the fraud – including claims against banks and payment professionals for breach of their obligations.
The CSSF is competent to receive complaints from customers of supervised professionals and to seek amicable settlement. A prior complaint to the firm is required before the CSSF accepts individual customer complaints. The CSSF also accepts general complaints denouncing breaches of applicable financial laws and regulations. This mechanism provides a regulatory-assisted resolution path for disputes with supervised financial-sector professionals.
Complaints to the CSSF create enforcement records that contribute to supervisory action against the entity. The CSSF publishes scam warnings and identity-theft warnings and can take enforcement action against unauthorised providers. Regulatory proceedings can result in licence suspension or revocation, fines, public warnings, and mandatory corrective measures. Regulatory findings may support civil claims by establishing that the entity breached its obligations under Luxembourg financial law.
Criminal complaints filed within hours of discovery give investigators the best chance of tracing funds before they are moved or layered through intermediary accounts. Bank recall mechanisms are most effective when initiated on the same day as the fraudulent transaction. Regulatory notifications filed promptly create contemporaneous records that strengthen both criminal and civil proceedings.
Named counterparties with identifiable assets in Luxembourg – bank accounts, real property, registered companies, vehicles – are the most viable targets for civil recovery and enforcement. Where the fraudster operated anonymously or through shell structures, criminal investigation through the Police Grand-Ducale and Public Prosecutor’s Office is the primary identification tool through bank records, platform data, and telecommunications records.
Where a regulated institution – bank, payment professional, investment firm, forex platform, or CASP supervised by the CSSF – failed to comply with its supervisory obligations, institutional liability claims provide an alternative recovery path against a solvent, regulated defendant. These claims do not depend on the fraudster’s identifiability or asset position and are particularly relevant where the fraudster has absconded or dissipated assets.
Contracts, payment records, communications, transaction references, and digital forensic evidence form the foundation for both criminal prosecution and civil recovery. Incomplete evidence – missing transaction references, deleted communications, unrecorded oral agreements – weakens both the criminal case and the civil enforcement position. Immediate, comprehensive evidence preservation at the point of discovery is the single most important step a victim can take to support recovery.
Fraud recovery in Luxembourg operates through criminal proceedings, civil litigation, CSSF complaint handling, and regulatory complaints – each channel serving a distinct function in identifying the fraudster, preserving assets, and achieving financial recovery. The CSSF supervises banks, investment firms, and other financial-sector professionals, and is the competent MiCA authority for CASP supervision – accepting complaints, publishing scam warnings, and seeking amicable settlement. The Police Grand-Ducale and Public Prosecutor’s Office handle criminal investigation and prosecution across all fraud types – with criminal complaints accepted directly by the Prosecutor’s Office as well as by the police. The Directorate for Consumer Protection handles unfair commercial practices.
Speed of reporting determines outcomes across all channels. Criminal complaints filed immediately preserve the investigative window for fund tracing and asset identification. Bank recall and chargeback mechanisms lose effectiveness with each day of delay. Evidence preserved at the point of discovery – contracts, communications, transaction records, digital forensic data – forms the foundation for every recovery action. CSSF complaints may be filed in English, French, German, or Luxembourgish, making the regulatory channel accessible for international clients – though early engagement of local counsel is recommended for court proceedings.
