A more thorough explanation:

A false claim is a statement or assertion that is not true. This can include overbilling, which is when someone charges more than they should for a product or service.

• A company claims that their product can cure cancer, but there is no scientific evidence to support this.
• An individual submits a claim to their insurance company for damages that did not actually occur.
• A contractor bills a client for work that was not completed or was done poorly.

These examples illustrate how false claims can be made in various contexts. In each case, someone is making a statement or submitting a request for payment that is not truthful. This can have serious consequences, such as legal action or damage to one's reputation.
