Firstly a simple divorce is a rarity, usually one of the parties is not happy about it and whilst unable to actually stop the divorce may well hinder the financial split.
In terms of cost, let us assume that you both agree to the divorce, then one of you petitions for it and wait for the other to sign the acknowledgement, and then the petitioner applies for the Nisi and subsequently the absolute
Providing everything goes as planned, costs are £300 for the petition and £40 for the absolute.
Now, comes the interesting bit, during the divorce proceedings one of you needs to apply for 'ancillary relief' or you both come to an agreement to settle the division of all your assets
If you think the finances are going to run smoothly, then come to a sensible agreement and put that to the court with an application for a
Consent Order
Providing everything is in order and appears to be fair on both parties a Judge should rubber stamp it and all is now in place and biding on both parties.
The cost of submitting the agreement for consent is very minimal about £40.
If one or either of you chose to use a solicitor for representation in the divorce proceedings expect to pay typically £500 on top
If one or either of you were to use a solicitor to represent you in the financial matters and an agreement is not reached, then typically expect costs for each of you to be in the region of £5000
The solicitors fees quoted are not clear cut, but they do typify should things not run smoothly
