The elements of a claim for negligent misrepresentation are (1) the representation was made by a defendant in the course of his business, or in a transaction in which he had a pecuniary interest; (2) the defendant supplied false information for the guidance of others in their business; (3) the defendant did not exercise reasonable care or competence in obtaining or communicating the information; and (4) the plaintiff suffered pecuniary (financial) loss by justifiably relying on the representation.

Justifiable reliance usually presents a question of fact. But the justifiable-reliance element can be negated as a matter of law (on summary judgment or directed verdict) when circumstances exist under which reliance cannot be justified.

In determining whether justifiable reliance is negated as a matter of law, courts consider the nature of the parties’ relationship and the contract. In an arm's-length transaction, the defrauded party must exercise ordinary care for the protection of his own interests.

A failure to exercise reasonable diligence is not excused by mere confidence in the honesty and integrity of the other party. And when a party fails to exercise such diligence, it is charged with knowledge of all facts that would have been discovered by a reasonably prudent person similarly situated.

Thus, that party cannot blindly rely on a representation by a defendant where the plaintiff's knowledge, experience, and background warrant investigation into any representations before the plaintiff acts in reliance upon those representations.

In South Carolina, a claim for negligent misrepresentation requires that the defendant made a false representation during their business or a transaction in which they had a financial interest, provided false information for the guidance of others in their business, did not exercise reasonable care in obtaining or communicating the information, and the plaintiff suffered a financial loss by justifiably relying on the representation. Justifiable reliance is typically a factual question, but it can be negated as a matter of law if the circumstances suggest that reliance was not justified. Courts will look at the relationship between the parties and the nature of the transaction to determine if justifiable reliance is negated. In an arm's-length transaction, the defrauded party is expected to exercise ordinary care for their own interests. A lack of due diligence, based on trust in the other party, is not a valid excuse, and a party is deemed to have knowledge of all facts that a reasonably prudent person would have discovered. Therefore, a plaintiff cannot claim justifiable reliance on a defendant's representations without proper investigation, especially when their knowledge, experience, and background suggest that such an investigation was warranted.
