In the UK you can make an order of information to compel directors of a company that is in debt to answer questions about company assets, accounts and records under oath. This can be done in County Court and my understanding it is inexpensive. I'm not sure how useful this is for carrying out an audit because I think its meant to be used for seeing if the debtor has the ability to pay. I think generally incorrect trading during an insolvency is meant to be discovered by the receivers during the insolvency process. Also, I'm not sure if there is an equivalent to an order of information in the US system.
