You do need to speak to your solicitor. Make sure they understand that you are struggling.
They will probably instruct a barrister for the final hearing. It may be someone you have met before. But it may not be. Ask if you can have a conference beforehand if you can afford that or if you are in receipt of legal aid.
If you feel special measures at court (separate waiting room, screens, more breaks) are required speak to your solicitor about whether they think you are eligible.
You will have to make a statement in advance of the hearing, setting out what you say is the right order and why. Your solicitor will draft that. Your ex will also make a statement. You get to see each other’s in advance of the hearing.
You should probably get to court an hour before the hearing is due to start.
The Cafcass officer will probably have been ordered to attend court. They will likely give evidence first and be asked questions by your representative and your ex’s representative. If you are the respondent your questions go last. if you agree with most of what they say your questions will probably not take so long.
Then your ex gives evidence and is cross examined by your solicitor or barrister. Then you give evidence and are asked questions by his. The questions of you will be aimed to show why he should have 50/50 care.
Then each representative makes submissions to the judge about what they say should happen and why. The applicant’s representative goes last when it comes to submissions.
The judge then delivers his or her decision which is called a judgment. Sometimes if time is running out the judge saves the decision for another day. This is called reserving judgment.
The applicant’s representative has to draft the order.
If you are unhappy with the decision you have 21 days to appeal. But it’s quite rare to successfully appeal and you need to show that the first judge got the decision “plainly wrong” or did not follow the correct procedure.
I really hope your solicitor is able to support you as you need and I wish you well.
