Legal Definitions - pessima fides

Definition: Pessima fides is a Latin term that means "the worst faith." It refers to a state of moral dishonesty.

Examples:

• A landlord who rents out an apartment with a known mold problem without disclosing it to the tenant is acting in pessima fides.
• A company that knowingly sells a faulty product without warning customers is also acting in pessima fides.

These examples illustrate how pessima fides refers to a deliberate act of dishonesty. In both cases, the person or company is aware of a problem but chooses not to disclose it to the other party. This is a breach of trust and a violation of ethical standards.
