This research aims to investigate the effect of controlling shareholder and corporate governance to audit quality measured with AQMS (Audit Quality Metric Score). The result of testing to a sample of manufacturing firms from 2008-2012 with a total of 432 observations shows that the alignment and entrenchment effect of controlling shareholder have positive effect to the audit quality. Corporate governance showed a positive effect to the audit quality, but it weakens the positive effect of alignment of the controlling shareholder to the audit quality.
