I understand you were declared bankrupt in August 2011, and this transaction occurred in May 2011. You are trading as an individual, have a number of debts, few or no assets or equity in your home and will not need credit soon and you are unlikely to inherit property in the near future. Hopefully you took professional advice before becoming bankrupt, which is not the easy way out many people believe it to be as you are deprived of the ownership of your estate.
I do not understand why the Official Receiver, acting as trustee, would be involved in a normal business transaction, which took place three months before you were declared bankrupt, it would not have been included in the statement of affairs when you petitioned the court and the OR would not have been notified until the bankruptcy order was made in August 2011. Were any bankruptcy restrictions applied or is there an investigation proceeding that could lead to a BRO or BRU?
