As a divorced person I would never judge you, it’s a nightmare and I can image what you’ve been going through. From my experience/understanding
Decree Nisi – court grants this to show there are grounds for a divorce
Decree Absolute – means its final and is rarely granted unless all the financials are sorted. Financials sorted can be clean break or they can be on going maintenance.
Congratulations on it being amicable, mine wasn’t and bill between the two of us was £60k approx, total waste of money.
In an amicable divorce / mediation you only need a solicitor to write up the “deal”, this can be pretty cheap as the documents and format are standard.
So I would say, get the decree NISI now and then apply for Absolute straight away on the basis the financials are agreed. You don’t need a clean break order IMO.
Note for Decree NISI you need to meet agreed criteria – adultry / separated for 2 years / unreasonable behaviour etc. The cause of the divorce makes no difference to settlement but is listed on court papers if you care. If you don;t care you can just sign that you’ve been unreasonable for example or slept with someone else (unamed).
