Have they asked for the info or has he?
If he's actually bankrupt now you can search here...
http://www.insolvency.gov.uk/eiir/IIRNameSearc hMapIE.asp. I'd suggest leaving the court and office as they are for a wider search.
This will give you the details of his insolvency practitioner and I would suggest she speaks to them if she has any uncertaintly.
Otherwise she could try the local Citizen's Advice Bureau (http://www.citizensadvice.org.uk/).
Hope she gets things sorted.
