The Utah Sandbox has slightly altered the list of legal innovations that can be tested in the Utah Legal Sandbox. They will no longer be allowing referral fee models. From statement:

It has become apparent, however, that the payment of referral fees—compensation paid to nonlawyers for the sole purpose of ensuring the referral of legal work—presents potential ethical challenges for lawyers and needs further informed consideration by the Court.

In light of this need for further study, as of today the Court is halting the consideration and authorization of bare referral fee arrangements paid by lawyers to nonlawyers.
