The current bill just has a brief few word summary of activities done with single total count of units (eg. 500). There is no indication as to which unit rate has been used, but dividing the total cost by the total units exactly gives the lawyer's hourly rate.
It is also very obvious a paralegal has indeed been used (possibly his wife). Messages from the lawyer's personal phone or email are barely understandable with poor spelling and atrocious grammar, yet formal paperwork is as would be expected from a professional. The paralegal's work however contains errors typical of dictation that the lawyer could never get wrong, showing it has not been checked by him.
