Capital confirmation is an audit procedure used to verify the accuracy and existence of a company's capital balances, including shareholder investments, partner contributions, and equity accounts. Auditors use capital confirmation to obtain independent evidence directly from shareholders, investors, or partners regarding the amount of capital invested in the business. This process helps ensure that financial statements accurately reflect ownership interests and capital structures. Capital confirmation is important because it reduces the risk of misstatements, strengthens audit evidence, and enhances confidence in financial reporting.
