“I’m going to court to sort out finances during divorce”
If you have children, apply to the Child Support Agency to calculate how much one parent should pay to the other (called maintenance). Calculate child maintenance via this link. You only need to go to court if there are more financial issues to sort out.
Fill in the form for a Financial Order and send it to the court (download here. To find your nearest court, put your postcode in here). If you can decide things beforehand with your ex-partner, draw up an agreement together (called a Consent Order), like this sample here. You can use a solicitor or do it on your own.
Go to court on the date you are given for the Final Hearing. The court will then make a decision about the case.
