What is Tort Of Deceit?

Legal Definition
The tort of deceit dates in its modern development from Pasley v. Freeman. Here the defendant said that a third party was creditworthy to the claimant, knowing he was broke. The claimant loaned the third party money and lost it. He sued the defendant successfully.

Deceit occurs when a person makes a factual misrepresentation, knowing that it is false (or having no belief in its truth and being reckless as to whether it is true) and intending it to be relied on by the recipient, and the recipient acts to his or her detriment in reliance on it.
