'Unbundling' means 'limited scope' means 'a la carte.' Somebody get a dictionary, please.
A la carte, from the French for "according to the menu," used to mean "separately priced items." As applied to legal services, it became "limited scope representation." Now the word for a la carte, or limited scope, is "unbundling."
It is not entirely new, having been offered by the American Bar Association years ago, but it is becoming more popular. That is, once you know what's on the menu and what to keep off the menu.
