Finance lawyer specialising in company transactions

Finance lawyer specialising in company transactions, I have a situation where I am being asked to provide questions regarding transactions within a U.K company as a former Director. I had sold the business before the company went into liquidation, I have limited access to documentation. The U.K company was purchased by a larger company in Dubai (sister company and person) - When the U.K company went into liquidation, the bank account was frozen for analysis. There were many payments to Directors which required explanation. The U.K bank account was being used by the Dubai company to receive funds due to not having its own bank account open (during 21-22). The company in Dubai has audited accounts by a global player who was aware of the use of the U.K bank for receipt of sales from Dubai. I need to understand more about how to explain this to the insolvency practitioner?
