I just read this on the app form guidance notes:


Please give details of any previous passports, covering the ast 10 years, including where these passports are now.
Where the information is available, please provide full details for each.
This should include travel document or passport number, issue and expiry dates and place of issue. Please tell us where your previous passports are (for example if lost, stolen, expired or returned to the
issuing authority and no longer with you).


So maybe its ok as he has a xerox copy with the details??
