Would the insurance company be able to refuse to sell a policy to a person? What reasons could be stated for this refusal?

The insurance company could not refuse to sell insurance to a person based on race, sex, religion, color, nationality, or ancestry. If it does so, it is illegal. Certain states might include other ‘prohibited classifications’ like age, marital status, language, occupation, physical or mental impairment, sexual orientation, geographic location, etc. to the list. Apart from the prohibited classifications, the insurance company might make a decision based on all the reasons that are related to the risk associated with the insured person. An individual would have the legal right for getting the information from the insurer about the reasons for refusing to sell the insurance policy.
