Years ago, when I was a member of a boutique litigation firm in Philadelphia, my partners and I would often ponder the question “How did we get this case?” What led this client to choose this law firm for this legal matter? Not infrequently that inquiry would lead to a surprising answer. The true origin would often turn out to be several degrees removed. The prospect had been referred by an existing client who had, in turn, been referred by another client and so on. It was truly remarkable how frequently a huge and lucrative legal engagement could be traced back to a minor favor performed for a person in need.
