What term is used when the majority of insurance written is for family members?

The term "Controlled Business" refers specifically to a situation in which an insurance agent writes a substantial portion of their business for family members or people with whom they have a close relationship. This term is significant in the insurance industry as control can lead to potential conflicts of interest. Regulators closely monitor controlled business practices to ensure that they do not lead to unethical practices or abuse within the insurance market.

In this context, other options do not capture the specific scenario described in the question. "Commercial Insurance" pertains to coverage designed for businesses rather than individuals or their family members. "Personal Lines" generally refers to type of insurance that covers personal, rather than commercial, risks, but it does not inherently imply a focus on family members specifically. "Group Insurance" is a type of insurance that covers a group of people, typically offered through an employer, and does not address the family-member aspect that "Controlled Business" does.

Thus, "Controlled Business" is the correct term as it accurately describes the practice of writing insurance primarily for family members, reflecting the close relationships that can influence the business.
