Decree nisi court fees

hi need some advice.
I need to attend court next Monday to pick up Decree Nisi but dispute costs. I issued the divorce petition against my ex on uNreasonable beh. It has all been accepted. I am seeking my court fees to be paid by ex and my solicitors fees ...what would I need to support my case. My ex has offered to pay £450 plus vat solicitors fees and half court fees, but I don''t see why I should pay anything when he wanted the divorce ?
I am in debt and he isn''t in his bank account but says he has liabilities of £20,000... Soft loans from family. This is the simple part, the financial dispute are completely different and I''m onto a second hearing in fen. He may be away on the date? Can he ask for a change of court date for Nisi, so he can dispute my claims?
Thanks

Hi

I may be wrong, but I believe that your stbx can object against costs and can apply to court prior to the Nisi reading to state that he will be attending to do so....

I''m sure wiser wikis will be along to advise further shortly

Yes he has cakes and flowers! And spending more money by sending his solicitor to defend his case. I really don''t need this prior to Christmas.
I have posted in general forum for some advice..desperately needed! I am not appointing solicitor for such low costs £1,100 approx. I am petrified though!
