Which of the following practices is NOT required under fair claims settlement practices in Illinois?

The correct answer is that "prolonged negotiation for maximum profit" is not required under fair claims settlement practices in Illinois. This practice goes against the principles of fair claims handling, which emphasize the need for efficiency and fairness in the claims resolution process.

Timeliness in settlement responses is a crucial aspect of fair claims practices, as it ensures that claimants receive prompt attention and resolution to their claims. Equitable treatment of all claims is also vital, ensuring that all claims are handled fairly without any bias or favoritism. Similarly, the absence of unjust discrimination in settlements is a foundational element that protects claimants from being treated unfairly based on irrelevant factors.

Prolonged negotiation for maximum profit does not align with these principles and could lead to delays and unfair treatment of claimants, which is why it is not considered a requirement under fair claims settlement practices in Illinois.
