Blocked investments lawyer in Paris: frozen savings, evidence and collective action.

Do not pay. In investment fraud cases, a demand for a tax on profits, administration fees or a guarantee at the moment of withdrawal is a recurring method: it extracts one last payment without ever releasing the funds. In a case decided by the Paris Court of Appeal, savers had paid more than €47,000 presented as a tax, without recovering the €60,000 they expected, and then discovered that the company had been struck off. The court nevertheless dismissed the couple's action against the bank, holding that “the customer is at liberty to dispose of their savings as they see fit, and to change their management habits, without this justifying any intervention by the bank holding the account” (our translation) (CA Paris, pôle 5 ch. 6, 19 March 2025, No. 23/19538). The lesson is twofold: the blockage should trigger an immediate halt to payments, and an action against the bank never rests on the loss alone. Keep the messages demanding the tax, the screenshots of the balance displayed and the statements, inform your bank, then file a criminal complaint with the complete list of transfers.

Not automatically. The transfers you ordered are authorised transactions within the meaning of Article L. 133-6 of the French Monetary and Financial Code (Code monétaire et financier), which rules out the refund regime for unauthorised transactions. The bank's liability is then based on the general law of Article 1231-1 of the French Civil Code (Code civil) and on its duty of vigilance. The Court of Cassation has recalled that “the banker's duty of non-interference in its customer's affairs yields, by virtue of its duty of vigilance, only in the case of an apparent anomaly” (our translation) (Cass. com., 2 May 2024, No. 22-17.233), and it dismissed the appeal. In practical terms, the saver must show that something visible to the bank, at the time of the transfer, should have alerted it: a beneficiary known to be fraudulent, an atypical destination, a manifest inconsistency with the usual operation of the account. A high or unusual amount is not always enough. The firm examines the statements and the orders one by one before advising on a complaint or an action, because a poorly supported claim risks being dismissed.

Only if the bank could see it. The Paris Court of Appeal ordered a bank to pay damages after it executed payments although the beneficiary was on the blacklist and appeared on the statement, relying on “the mention on the statement, drawn up by the bank itself, of a payment beneficiary entered on the AMF blacklist at the time of the transaction” (our translation) (CA Paris, pôle 5 ch. 6, 9 July 2025, No. 23/10785). Conversely, the same chamber ruled out liability where the transfers were made to companies other than the listed platform, in countries of the European Union that “were not placed in particularly high-risk zones” (our translation) (CA Paris, pôle 5 ch. 6, 26 November 2025, No. 24/08247), and where the listing came after the transfers (CA Paris, pôle 5 ch. 6, 30 April 2025, No. 23/05410). Two dates therefore matter: that of the AMF publication and that of each transfer. The name of the beneficiary as it appears on the statement counts as much as the platform's trading name. The firm compares these elements before any complaint.

Yes. Even where the bank is found at fault, the judge may reduce the compensation by taking the saver's negligence into account. In the case in which the Paris Court of Appeal found the bank in breach, it also noted that the customer had contributed to their own loss by failing to find out about their contact and “by yielding to the promise of substantial gains through the supposed acquisition of unusual and unregulated products” (our translation) (CA Paris, pôle 5 ch. 6, 9 July 2025, No. 23/10785). The compensation awarded was lower than the sum claimed and the claim for non-material harm was rejected for lack of an established causal link. Redress also often takes the form of loss of an opportunity, not full reimbursement of the transfers. The response to this argument should therefore be prepared from the outset: the saver's profile, the documents received, the apparent seriousness of the platform, the pressure techniques used and the verification steps taken. These elements do not remove the victim's fault, but they weigh on the share left to be borne by them.

The evidence is rebuilt from what you hold and from what third parties hold. On your side: bank statements, transfer orders, confirmations through the app, emails, messages, screenshots, contracts and telephone numbers. On the side of third parties: the bank keeps the orders and supporting documents, and Article 145 of the Code of Civil Procedure allows the court to be asked, before any trial, for the investigative measures that are useful where there is a legitimate reason. The urgent applications judge of Béziers thus ordered a bank to disclose contested transfer orders, recalling that “the expiry of the limitation period does not prevent the judge from ordering production of the document that may have been kept” (our translation) (TJ Béziers, référés, 18 September 2026, No. 26/00401). The same order, however, limits disclosure to the documents that the bank was required to keep for ten years. You therefore need to act before the documents fall outside that period. A single chronology linking each transfer to a message received then makes the file readable both for the investigator and for the civil judge.

A criminal complaint is useful, even where the perpetrators are abroad. Fraud requires the use of a false capacity or fraudulent manoeuvres inducing the victim to hand over funds; it is punishable by five years' imprisonment and a fine of €375,000 under Article 313-1 of the French Criminal Code (Code pénal). Providing investment services without authorisation is also punishable under Article L. 573-1 of the French Monetary and Financial Code. The complaint brings the facts to the attention of the authorities and may lead to an investigation that traces the receiving accounts and, if the conditions are met, carries out seizures. It also dates the moment the fraud came to light, which may matter for the limitation period of the action against the bank. Article 85 of the Code of Criminal Procedure (Code de procédure pénale) then opens the complaint with civil-party petition before the investigating judge, if the public prosecutor has indicated that no prosecution will follow or if three months have elapsed since a complaint lodged with the prosecutor in return for a receipt or by registered letter with acknowledgement of receipt, or since a copy of the complaint lodged with the investigators was sent in the same forms. Article 2 of the same code reserves the civil action to those who have personally suffered the harm caused by the offence.

A liability action against the bank is subject to a five-year limitation period running from the day the saver knew or should have known the facts enabling them to act (Article 2224 of the Civil Code). The whole debate concerns this starting point. The bank often argues that the customer should have had doubts from subscription or from the absence of income. The Limoges Court of Appeal set this argument aside for a lay saver who had received regular payments from the company, holding that “he could only determine that it was doubtful from the day he became aware of this fraud” (our translation) (CA Limoges, ch. civ., 29 April 2026, No. 25/00620). It took the date of his complaint and declared his action admissible. This outcome depends on the facts: payments received, public warnings, AMF sanctions, exchanges with the intermediary. In criminal law, the public prosecution of offences (délits) is subject to a six-year limitation period under Article 8 of the Code of Criminal Procedure. The firm fixes the most cautious date and acts accordingly.

Yes, through several routes that follow distinct conditions. Associations whose stated corporate purpose expressly includes the defence of investors in financial securities or products may act before any court, including by civil-party petition, for facts harming the collective interest of investors, provided they are approved or meet the voting-rights criteria set out in the text and have sent their articles of association to the AMF (Article L. 452-1 of the French Monetary and Financial Code). Where several individual investors have suffered individual harm caused by the same person and having a common origin, such an association may bring an action for compensation in their name if it has been given a written mandate by at least two of them (Article L. 452-2 of the French Monetary and Financial Code). The class action was also reformed by Article 16 of Law No. 2025-391 of 30 April 2025, which in principle reserves it to associations approved for that purpose and opens it for a single breach, or a breach of the same nature, by a professional. Persons who could act under the former regime keep that option for two years from 3 May 2025, and actions brought before publication of the law remain subject to the former provisions. Before the criminal court, each victim may also join the same proceedings as a civil party. The choice depends on the identity of the solvent parties responsible, the number of victims and the shared evidence. The firm can act for a single saver or for a coordinated group, ensuring that each claim remains individualised.

It remains demanding. Before the reform that came into force on 3 May 2025, the Paris judicial court (tribunal judiciaire) declared inadmissible a consumer association's class action concerning structured funds, recalling that it is for the claimant association to prove a breach by the professional that caused individual harm to consumers in a similar situation (TJ Paris, actions de groupe, 3 April 2024, No. 18/02914). The text then applicable has been repealed and replaced by the unified regime of Article 16 of Law No. 2025-391 of 30 April 2025, which covers a single breach or a breach of the same nature and makes it possible to seek cessation of the breach, compensation for the harm, or both. The logic remains: there must be an identified and solvent defendant, often a bank or an intermediary, and a demonstrable common breach. Against anonymous fraudsters based outside the European Union, the class action offers little; a coordinated criminal route and an individual action against the bank then remain more realistic.

Not always. Where the issuing company is in judicial liquidation, only the liquidator has standing to act in the collective interest of the creditors. In the Aristophil case, investors accused the banks of having enabled the fraud; the Court of Cassation dismissed their appeals, holding that “the harm resulting from a fault that contributed to the cessation of payments is therefore collective harm for which only the liquidator may seek compensation” (our translation) (Cass. com., 10 June 2026, No. 24-18.425). The investors who claimed the sums declared in the insolvency were held inadmissible. This unfavourable decision requires a distinction between two kinds of harm: that corresponding to a fraction of the liabilities, reserved to the liquidator, and separate harm of the saver's own, which the saver might still invoke, for example against their own bank for a breach towards them. Filing the claim within the time limit remains essential. The firm checks the state of the insolvency proceedings before any writ of summons.

Impersonating a well-known bank makes the investment credible: letterhead documents, a fake adviser, rates above the market, then a transfer to an account opened elsewhere. The imitated bank is not, as a matter of principle, a debtor to the saver who was not its customer. The question shifts to the bank that executed the transfers and, sometimes, to the one that opened the receiving account. For the first, the Court of Cassation requires a detectable anomaly. In a case of forged transfer orders, it endorsed a court of appeal that had ruled out fault after finding that the transfers remained within the agreed limits, were covered by the balance and that “the destination of the transfers was an account held in the books of an authorised bank in a European Union member state that did not particularly attract attention in terms of security” (our translation) (Cass. com., 12 June 2025, No. 24-10.168), the appeal being dismissed. A destination within the Union is therefore not, in itself, an anomaly. Everything the bank knew needs to be documented: stated purpose, exchanges at the branch, limits raised, alerts received. Immediate notification to the bank whose identity was used also helps the investigation.

Not on the sole basis of the lack of authorisation. Article L. 532-1 of the French Monetary and Financial Code makes the provision of investment services subject to authorisation, and the chairman of the AMF may serve formal notice on operators of unauthorised online offers, then ask the president of the Paris judicial court to order them blocked, under Article L. 621-13-5 of the French Monetary and Financial Code. But the Court of Cassation holds that failure to meet the authorisation requirement “cannot have the effect of rendering the contracts entered into null” (our translation) (Cass. com., 9 July 2025, No. 23-15.492). It does accept, however, that this failure engages the provider's civil liability where it causes its counterparty personal and direct harm linked to the loss of the safeguards that authorisation provides. The judgment concerned an underwriting service between companies and addresses only the lack of authorisation: it rules neither on other investment services nor on a nullity based on another ground, which remains to be examined in light of the facts. For the saver, the safest route on this ground is therefore compensation, and it requires an identifiable and solvent defendant. Against an anonymous platform, the criminal complaint and the examination of the bank's liability take over.

Within certain limits. Article 706-14 of the Code of Criminal Procedure allows the victim of a fraud who cannot obtain effective and sufficient redress, and who is as a result in a serious material or psychological situation, to apply for compensation if their resources are below the ceiling for partial legal aid. The compensation is capped at three times the monthly amount of that ceiling: it never compensates for substantial savings. The Nancy Victims' Compensation Commission (CIVI) also declared inadmissible an application made after the death of the victim of a large-scale fraud, noting that “the successors of the deceased victim have no standing, solely as the victim's heirs, to claim the benefit of the compensation” (our translation) (TJ Nancy, CIVI, 21 January 2025, No. 24/00794). The application must therefore be made by the victim in person, with proof of resources and proof that redress cannot be obtained elsewhere. This route complements the others; it does not replace them.

Caution is required. After a fake investment, victims often receive offers from recovery companies, so-called investigators or fake lawyers who demand advance fees, a percentage or remote access to the computer. These approaches frequently follow the same pattern as the original fraud. Before any exchange, verify the identity of the person contacting you: a lawyer is registered with a bar, and that registration can be checked with the bar concerned. No serious professional can guarantee the return of the funds, because it depends on identifying the accounts, on the seizures made in the investigation and on the solvency of those responsible. Do not give banking credentials or a copy of an identity document to an unverified contact. The firm examines the documents in a preliminary review, with no promise of result, and indicates which routes remain open in light of the case law, including where it is unfavourable. Also report these new approaches in the complaint already filed.
