I must admit - stressful as the process was (I was at the end of my tether around Christmas time) - I do feel I got "my day in court" in the private FDR. I didn't have to say a word - you have a Barrister to do all the talking - I know you can represent yourself, but if it's acrimonious, I would strongly recommend a good Barrister because they really know their stuff.
I was very lucky with my legal team. My solicitor and Barrister were on my side throughout, and I seriously couldn't have managed without them - I felt so ground-down by my ex-H. It felt good to have a Judge come down on my side, after ex had sent so many barbed solicitor letters implying I was being unreasonable and that the Judge would "take a red pen to my demands." Judge didn't! And specifically wrote in the indication that he wouldn't as in his opinion my needs were reasonable.
It would depend on what assets you're arguing about - we had a pot (including his massive pensions) of about £2M so the costs incurred for the solicitor and the pFDR/Barrister were worth it for me.
FDR Judge was v clear that if we went through the whole court process, we would probably spend the money we were arguing about on legal fees - and thank god ex listened and we agreed at the first stage. My Barrister did tell me afterwards she feared he might take it further out of spite - kind of "I'll spend it all on lawyers rather than give it her!" but thankfully not.
I can't stress this enough - get a solicitor who you feel is good, knowledgeable and on your side. I spoke to a few, and some were really blunt, just firing questions. The one I went with made me feel listened to and looked after. Legal fees mount up quickly though - I spent about £14,500 on solicitor's fees since Jan 25 and about £7,000 on the private FDR. I gained far more in the settlement, so more than worth it for me.
Good luck and keep your wits about you! Get the Form E done & exchanged if you haven't yet, and then do a spreadsheet of all the assets - house value/equity, savings, pensions, cars and so on - so you know the exact figures you're arguing about. You don't want to fall into the trap of spending more on legal fees than you gain in a settlement.
