Hi Graham, regarding csa payments the following is from the technical manual that the OR uses:
31.7.32 Maintenance payments
An obligation arising under an order made in family proceedings or under a maintenance assessment made under the Child Support Act 1991 is not a debt provable in bankruptcy . It is a continuing obligation, payable out of income.
Basically this says that any CSA liability cannot be claimed in bankruptcy, so legally you have to continue paying it, and can be listed in your income and expenditure, as a an expense payable out of income(but you should clearly identify this on the SOA - statement of affairs).

If you need help completing SOA's(statement of affairs) or PIQ's(preliminary information questionnaire) if you've been declared bankrupt, or anything else and you're within 30 miles or so of Warrington, then please contact me via my contact details in the expert page for futher details"
