A referral arrangement is not the same as representation, and the difference decides who is legally obliged to act for the seller. A licensed broker represents the policyowner and is a fiduciary to them. A referral firm introduces the policyowner to that broker and is paid when the case closes.
Neither is improper. Both are common. What separates a good referral firm from a bad one is whether it says which brokerage the case goes to and what it earns when the case closes. Citizens Life Group says both, in writing, before anything is signed. Most referral operations in this market say neither.
