This book is a complete undergraduate textbook on the theory, standards, and statutory framework of financial audit in India, developed along the real arc of an engagement—from objectives, planning, internal control, evidence, vouching, and verification, to the auditor's appointment, report, and liabilities, and on to bank, insurance, and forensic audits. Every concept is anchored to the relevant ICAI Standard on Auditing, the governing section of the Companies Act, 2013, and the decided case that shaped it. Across fifteen chapters mapped to the five syllabus units, it pairs lucid, example-led exposition with comparative tables, chapter-end 'Test Your Knowledge' sets, and three solved previous-year papers. This 3rd Edition, by Dr Aruna Jha and CA. (Dr) Anuj Bhatia, is fully updated to the latest University of Delhi syllabus (DSE-5.5: Auditing), the revised SA 700 reporting series, and the NFRA regime.
