Dear Ms O'Connell The reply I have received is:- "There is no requirement for the field 'former names' to be completed. The check is not a mandatory field.". So, if that part of the form is not completed, it would not be rejected solely for that reason. ----- Original Message ----- Dear Companies House, As part of my duties as a councillor on Cambridge City Council, I have been asked to become director of an external organisation. The AP01 form has a field for "former names", but as I hold a Gender Recognition Certificate this is not public information. Specifically, disclosure of former names by others is prohibited under s22 of the Gender Recognition Act 2004. Is it acceptable to leave this field blank? Kind Regards, Zoe
