About 22 percent of law firms in a new survey said they are profiting by offering alternative fee arrangements (AFAs) to corporate clients. But that means some 78 percent haven’t figured it out yet.

“AFAs only work when your client relationships are at the absolute highest levels of trust—not just a good relationship—but a deep, embedded relationship,” says The Mad Clientist, a blog from BTI Consulting Group. BTI partnered with Law360 to survey 750 law firm attorneys about their fees.
