Rule 5.4 prohibits a lawyer from paying a referral fee to a nonlawyer. Indeed, it prohibits sharing any fees with nonlawyers.
The respondent was a personal injury lawyer who paid two nonlawyers substantial referral fees for referring a personal injury case to him. The two checks amounted to $48,500 and $20,000. One of the checks was paid to a local police chief.
Comment: the lawyer was extremely lucky to escape with a reprimand.
