This article examines the design of contingent fees for plaintiffs' la
wyers in a legal system that gives parties the choice between going to
trial and settling out of court. Using a simple principal-agent model
with attorney moral hazard, the article shows that the client general
ly benefits from a bifurcated fee structure in which the attorney gets
a large fraction of the recovery in the event of trial but a small fr
action in the event of settlement; this structure maximizes both the s
ize of the recovery and the client's distributive share of it. The art
icle also examines the limits on the use of this fee structure that ar
e imposed by two aspects of the settlement bargaining process: (I) the
allocation of settlement authority between lawyer and client, and (2)
the relative bargaining power of plaintiff and defendant.
