This paper investigates the impact of corporate governance on capital structure in non-financial firms listed on the Nairobi Securities Exchange, using a sample of 30 companies from 2007 to 2011. The results indicate a positive correlation between total debt to asset ratio and CEO duality, while larger boards and higher ownership concentrations correlate with lower debt levels. The study emphasizes the importance of good corporate governance practices for enhancing firm value and mitigating risks associated with financial management.
