Increased merger and acquisition activity appears to be the most recent trend in the legal services industry. As a result of this activity, independent mid-sized law f m are believed to be at a competitive and marketing disadvantage. A response to this situation has been the formation of cooperative associations among indepen- dent law fums. While Lhese networks are becoming more popular, often member firms do not receive the "hoped-for" benefits associated with network membership. This paper examines this trend and provides the results of an in depth case analysis of a "typical" network. A Key Success Factors Model is provided to improve the performance of legal networks and the implications of joint market- ing effom are illustrated.
