The market to provide legal services is a competitive one, and law firms are not competing only with one another. That’s a familiar refrain as reports come steadily about the Big Four accounting firms’ exploits overseas.

In the U.S. generally, and in New Jersey specifically, the picture is much different. Laws and ethics rules—chiefly those prohibiting the practice of law by nonlawyers and barring legal fee-sharing with nonlawyers—are major impediments to the sort of market-shifting moves happening in Europe and Asia.
