This paper examines the role of social capital in professional-client relationships. We consider exploring the effects of social capital on the creation of human capital, a subject which is worthwhile investigating within all professions. In this paper, we concentrate on what are known as the structural and attributive dimensions of social capital and aim to understand their effects on the knowledge acquisition of professional practitioners. We analyse the association between social capital and human capital (i.e., knowledge acquisition) in the context of the lawyer-client relationship. Through the application of social capital theory, this paper seeks to advance our knowledge of the relations between professionals and clients. More importantly, the study contributes to improving our understanding of the role of social capital in influencing a lawyer's ability to retain and win new clients.
