What is fraud? Definition and tips

How do you define fraud?

Definition of fraud

Fraud can be defined as a deliberate action aimed at deceiving, duping or swindling someone in order to obtain an illegitimate personal advantage. It generally involves the use of illicit means, such as falsifying documents, manipulating data or deceiving people in order to obtain money, goods, services or any other form of material advantage.

What is considered fraud?

To qualify as fraud, the act in question must have been committed intentionally. This requirement is also a fundamental principle of criminal law: according toarticle L121-3 of the new Penal Code, “there isno crime or misdemeanor without the intent to commit it“. However, assessing the intentional element can be particularly tricky in practice. Thus, according to the aforementioned standard, an unintentional inaccuracy in the accounts – even if material – constitutes an error and not fraud.

To be considered a fraud, it is therefore important to take several elements into account:

  • The commission of an act: Fraud always involves a concrete act rather than a mere idea or intention.
  • Willfulness: The fraudulent act must have been committed deliberately and intentionally.
  • Assessment: Intentionality can be difficult to prove legally, as it is based on subjective elements such as the fraudster’s intentions and motivations.
  • Unintentional vs. Intentional: Unintentional errors are not considered fraudulent practices, even though they can have significant consequences.

What's the difference between error and fraud?

While both involve incorrect behavior, they differ in intent and impact.

An error is generally the result of an involuntary action or negligence. It can occur due to misunderstanding, distraction or lack of skill. The consequences of an error may vary depending on the context, but they are rarely intentional and can often be corrected with appropriate measures.

Fraud, on the other hand, implies a deliberate intention to deceive or harm others. It is based on a deliberate act aimed at obtaining an unfair advantage or causing losses to a third party. Fraud can take many forms, such as falsification of documents, accounting manipulation, misappropriation of funds or fraudulent use of goods or services.


  • A mistake is unintentional, while fraud is deliberate.
  • Errors are the result of negligence or misunderstanding, while fraud aims to deliberately mislead or cause damage.
  • An error can usually be corrected, whereas fraud can lead to serious consequences and financial loss.

What's the difference between fraud and corruption?

Fraud and corruption are two distinct concepts, although they are often associated due to their similar characteristics. Here are a few key points to differentiate these two concepts:


  • Fraud can be defined as a deliberate action aimed at deceiving or misleading others in order to obtain an illegal or unjustified advantage. It often involves the manipulation of information or goods.
  • Corruption, on the other hand, is when a person in a public or private positionabuses his or her power in exchange for a personal advantage or to further the interests of a third party.

Players involved

  • Fraud can involve individuals as well as entire organizations acting in their own self-interest.
  • Corruption usually involves government officials, civil servants, managers of state-owned companies and sometimes even politicians.

Methods used

  • Fraud can take many forms, depending on the context, such as financial embezzlement, counterfeiting, misappropriation of funds or identity theft.
  • Corruption is mainly based on the use of bribes, favoritism and misappropriation of public funds.

Legal consequences

  • Both offences are generally prosecuted and punished by law, although sanctions and penalties may vary according to the seriousness of the act committed and the jurisdictions involved.

What to do in the event of fraud

What to do if you are a victim of fraud?

When faced with a fraud situation in France, it’s vital to take appropriate measures to protect your interests.

Whatever the type of fraud, the first step is always to contact the local police or gendarmerie to provide them with all the relevant details, such as dates, amounts of money involved and available evidence. Be sure to keep a copy of the incident report for your records.

Here are the steps you can take if you are a victim of fraud, depending on the type of fraud:

Bank card fraud

Report fraud on Perceval

After informing the local police or gendarmerie, it is strongly recommended to report it to Perceval, an online service managed by the French Ministry of the Interior.

Block your bank card immediately and inform your bank

You must block your card (or temporarily deactivate it) and stop payment! This means your credit card can no longer be used. To do this, go to the personal area of your bank's website or application, generally to the section concerning your bank card. You should also inform your bank of any details of the fraud, including suspicious transactions and any compromised bank accounts or cards. Your financial institution may then take steps to block or cancel these fraudulent transactions.

Check your bank statements regularly

You should carefully check all your recent financial transactions to identify any suspicious or unauthorized activity. If you spot transactions that are not yours, report them immediately to your bank and follow their instructions.

Identity fraud (impersonation)

Contact all credit providers immediately

You must cancel all your cards and direct debits, with the exception of regular debits such as rent or electricity.

File a complaint with the appropriate authorities

This will not only prove your good faith in the event of subsequent problems, but also initiate a potential search for possible suspects. To do this, go to your nearest police station or gendarmerie and lodge a complaint against X for identity theft. You can also send your complaint directly to the Public Prosecutor. It's essential to have a copy of this complaint, as you'll be asked for it when dealing with banks or government agencies. An official database of identity theft victims has been set up by the national police force, and is accessible only to law enforcement officers.

Cancel your stolen ID and apply for a new one.

Check that you are not registered with the Banque de France

Fichier central des chèques and Fichier des incidents de remboursement des crédits aux particuliers.

Computer fraud

Change all your passwords and strengthen the security of your online accounts

If you suspect your credentials have been compromised, it's crucial to change your passwords immediately and activate additional security measures, such as two-factor authentication.

Online fraud

Report the incident to the relevant platform

Major online service providers, such as social networks or e-commerce sites, generally have specific procedures for reporting and dealing with cases of fraud ("Report abuse" or "Report an ad").

Commercial fraud

Inform the fraud control authorities

If you notice any infringements of consumer protection rules (misleading advertising, price manipulation, counterfeiting, etc.), it's important to inform the DGCCRF (Direction générale de la concurrence, de la consommation et de la répression des fraudes) immediately. This report may concern a store, a website or a company. After investigation, the government department can require commercial fraudsters to comply with their obligations, or face sanctions.

Remember that each fraud situation can be unique, so it’s important to follow the specific instructions listed by the relevant authorities and your financial contacts. Quick action is often crucial when it comes to minimizing the damage caused by fraud, so don’t delay if you fall victim to such a situation.

Who is liable for bank fraud?

In 2023, the bank is liable and must reimburse the user in the event of bank fraud if, and only if, the user can prove that the attack was not due to negligence on its part. As a result, both the user and the bank now have obligations of vigilance: they must take preventive measures to secure their personal data (login, password) and inform their bank as soon as possible of the fraud they have just been the target of.

However, this balance has not always been so clear-cut: explanations!

Before 2017, jurisdictions were rather lenient towards users who were victims of bank fraud. They relied heavily on the French Monetary and Financial Code (CMF) to demand repayment of transactions contested by the banks. The courts emphasized that banks had a duty to carefully monitor transactions on their customers’ accounts throughout the business relationship. As a result, bankers had to exercise their duty of vigilance in accordance with their rights and obligations.

All a user who had been the victim of bank fraud had to do was invoke article L133-18 of the French Monetary and Financial Code: “In the event of an unauthorized payment transaction reported by the user under the conditions set out in article L. 133-24, [la banque] reimburse the payer for the amount of the unauthorized transaction immediately after becoming aware of the transaction or after being informed of it, and in any event no later than the end of the next business day“.

Once the fraudulent transaction had been reported , the bank was legally obliged to reimburse the amount of the disputed transactions, as well as the interest and fees associated with them.

How can you prove bank fraud if the bank refuses to reimburse you?

Since the January 18, 2017 ruling by the French Supreme Court (Cour de cassation), the onus has been on the bank to provide evidence of negligence on the part of the user in the event of a refusal of repayment. On November 12, 2020, a new ruling by the French Supreme Court (Cour de cassation) specifies that, in addition to this evidence, the bank must now prove the absence of a technical deficiency (computer problem linked to its payment device) at the time of the facts. However, it remains essential for the user to prove her innocence by gathering all the evidence at her disposal.

First of all, judges base their assessment of gross negligence in bank fraud on factual elements. The latter is assessed independently of the victim’s personal characteristics, such as age or perception of fraud, or level of computer literacy. So, whether or not you’re aware of the risks of phishing attacks, the court won’t look to see if you’re an expert in cybercrime or a complete novice in the field.

Here are the questions you need to answer to build a strong case for bank fraud:

By behaving attentively, the court could potentially consider that you have taken all reasonable measures of vigilance. You will then be refunded at least the full amount illegally taken from your account.
