Hello, welcome to the website. My name is Tony, I can assist you with this.
Have you tried to reach agreement with her to pay half of the costs each?
No, I am keen to conclude this matter as quickly as possible
Okay, it is worth doing this, these matters normally resolve on that basis. It's common to see a draft order or request for costs be paid by the respondent (you), because that's just what a petitioner's solicitor would do, but normally, on amicable divorces, the parties will agree to go 50:50. Your request for this would not be surprising and should be agreed to.
All that being the case, without consideration of issues concerning financial relief etc., for a simple straightforward uncontested divorce you would be looking at c. £800 in total, so £400 each or so.
The costs shouldn't be too different from that.
