As most commonly used in legal settings, an audit is an examination of financial records and documents and other evidence by a trained accountant. Audits are conducted of records of a business or governmental entity, with the aim of ensuring proper accounting practices, recommendations for improvements, and a balancing of the books. An audit performed by employees is called "internal audit," and one done by an independent (outside) accountant is an "independent audit." Auditors may refuse to sign the audit to guarantee its accuracy if only limited records are produced.
