Sorry, been very busy @ work.
Do NOT declare bankruptcy. Call the banks, talk to them to arrange a repayment plan. It may seem easier to just declare bankrupt but trust me that it is NOT!
I did the maintenance order and PPO separately, and did everything myself. Possibly that's why we were routed to a mediator instead of having a court session for the maintenance. PPO was both of us in court - quick session since he did not contest it.
Since you have hired a lawyer, if you trust that he will fight for your demands, then do not attend. Let the lawyers do the talking. But you might just attend anyway, to know exactly what's going on.
