keep it child-focused and try your best to avoid bashing the ex.
first hearing is quite basic. court wants to know what the issues are. in my case was ex denying overnight stays with kids. you will probably see a social worker (cafcass) hanging around. make sure you speak to him/her. they will try to reach agreement with your ex. but its probably unlikely. cafcass or your ex side might ask for fact finding hearing. Try your best to avoid that, as it will just mean more delays, and you having to possibly wait even longer to see your kids. i was able to avoid. and instead cafcass did Section 7 report, in time for 2nd hearing.
