you need to know your financial position, income needs and how you and your children can be housed. if there are any inconsistencies with your partners financial disclosure you will need to submit any evidence before the hearing . more importantly you should be clear on arrangements for your dependent children, this will also inform your housing and income needs. if your ex has a solicitor write to them and let them know you do not have a solicitor and provide your current income details as you say this was incorrectly presented at FDR and ask if there is any further information needed from you . have you received any sort of open proposal for settlement? and do you have an idea of what you would like to achieve?
basically you both get to present your case/facts to the judge, who will in accordance with the law will decide on any issues which are contested. ( look at section 25 matrimonial c act criteria which details the legal considerations) so its worth spending time looking at budgets and what is reasonable for both of you . in my experience x''s solicitor was a pretty slippery character, but don''t be intimidated, do your homework and if you are honest and fair you need not be scared. if you don''t understand anything don''t be afraid to ask. the main priority, quite rightly is welfare of the children. if it''s got to a FDR then you clearly don''t agree on certain issues...identify the issues and consider what his argument may be and how you may counter this and any evidence you have to support your position...good luck
