hello zac, yes you do need to list this income. Although, the child benefit and the maternity pay will not be used in an IPA if you should have one. There is something an OR can do with the Tax Credits but, it's complicated.Look on the insolvency site for further publications regarding bankruptcy and Tax Credits.
As for which courthouse to use. Use the one nearest you. Also, contact the courthouse and see if you need an appointment to petition. Some courthouses require an appointment (mine did) others do not. Another word of advice. If any of the debts are jointly held, your wife will have to file for bankruptcy or the creditors will come after her for payment.
An IP expert will come along soon to assist you, zac. I just didn't want you thinking there was no one here(smile)to read your post.
There is also a sister site that deals with bankruptcies:

Take care.
All I have left is my humour.
