In reply to steveej:
It’s impossible for anyone, professional or otherwise to give you any advice without knowing what the issues are.
Procedurally though, if you’re a litigant in person and your ex wife is represented her solicitor should be preparing the bundle, even if she is the respondent. There won’t be witness statements in a FHDRA, just the application, response, directions order and CAFCASS letter (if there is one). Filing loads of documents which you haven’t been directed to is a great way to piss off a judge at the start.
don’t expect anything meaningful to happen at the first appointment. Unless the issues between you are simple (like handovers being on a Wednesday or a Thursday, in which case the judge will just tell you to go outside and sort it out) it will all get timetabled off to another hearing. It’s impossible to say how that will play out on the information you’ve given.
