A director of a company can be disqualified for a number of reasons, including fraudulent trading, wrongful trading, or ‘unfit’ conduct. If disqualified, a director may not act as a director or manager during the disqualification period, if they do, it is a criminal offence. The penalties are imprisonment and personal liability for the relevant debts of the company. If a director of a company you are trading with is disqualified then this is a major red flag and you should seriously consider whether you can continue to trade with them.
