A lawyer may not split legal fees with a non lawyer assistant nor pay a non-lawyer assistant for the referral of legal business. A lawyer may compensate a non-lawyer assistant based on the quantity and quality of the non-lawyer assistant's work and the value of that work to a law practice, but the non-lawyer assistant's compensation may not be contingent, by advance agreement, upon the profitability of the lawyer's practice.
