Weakness abuse

Verified 07 February 2023 - Directorate of Legal and Administrative Information (Prime Minister), Ministry of Justice

Abuse of weakness is the abuse of a person by taking advantage of their ignorance or its physical or mental weakness. For example, signing a document that is not suited to the person's needs or handing over a large sum of money that has serious consequences for their property. If you're a victim, you can complain to convict the perpetrator and receive damages. We will explain the facts that are being suppressed and tell you what steps are being taken.

Weakness is abused when someone takes advantage of the vulnerability or to cause it to do something that is contrary to its interests.

The offender has knowledge of the state of weakness and ignorance of his victim.

Vulnerability may be due to age, illness, physical or mental disability.

The victim may be, for example, a minor, an elderly or disabled person, or a pregnant woman.

The perpetrator may also exert severe and repeated pressure to manipulate the victim in such a way as to distort his judgment.

Examples of abuse of weakness

Abuse of weakness can take a variety of forms:

  • Door-to-door sales or telephone sales when the person is taking advantage of the person's vulnerability. The same applies to transactions carried out in places not suitable for sale (parking, hotel, etc.).
  • Sale at too low or unnecessary price, such as the subscription of an internet subscription by a person who does not have a computer
  • Transactions concluded in the emergency when the victim did not have time to have a quote (for example, lock, car or heating breakdown)
  • Psychological pressure exerted on a person under the influence of a cult, sectarian movements or even a third party (a neighbor, a friend, a family member, etc.). Such pressure must lead it to do something that is contrary to its interests.
  • Large and unusual remittances (transfers, checks, payment by credit card, bank withdrawals) made by particularly vulnerable persons. The same is true of unwarranted proxies (most often bank proxies).
  • Not doing anything (for example, being induced not to refuse a loss-making estate).

Difference from breach of trust

Abuse of weakness should not be equated with breach of trust.

  • In breach of trust, the perpetrator misappropriates the property or funds of the victim who placed his trust in him.
  • In the abuse of weakness, the perpetrator takes advantage of the person's vulnerability to lead him or her to do or refrain from doing an act that may be harmful to him or her.

The victim does not measure the scope of his commitment and ignores the consequences of his actions. She is unable to cope with the pressure because of her fragility.

This weakness may result from any of the following:

  • Age. For example, the elderly person who does not measure the financial consequences of his employment or the minor who takes out a contract without having the legal capacity
  • Physical or intellectual disability (physical or mental disability, illness)
  • Sustained or momentary depression, economic situation, psychological state, isolation, separation,...
  • Lack of knowledge of the language, which can for example lead to a lack of knowledge of the value of money
  • Low education

If you are a victim, you have several options:

  • Either obtain the amicable resolution of the contract.
  • Or, if the amicable procedure does not succeed, obtain from the judge the judicial resolution of the contract and any damages.
  • Either file a criminal complaint. This can result in the criminal conviction of the perpetrator and compensation for your damage.
