Although it is entirely possible to agree everything between one another, either party can still apply to the court at a later date, unless the have remarried, and ask the court to make an order in different terms, and this does sometimes happen. An order made by the court is final, unless it can be shown that one or other party has misled the court, except for maintenance orders which are ongoing and can be reviewed whenever either party's circumstances change. If everything si agree the court can be asked to make an order by consent, and will only need limited information about the parties finances this is done on a form 2.62. The court will also want the order laid out in stansard terms, and a fee is payable. The court will only make the order if it is fair and reasonable. Once everything is agreed it is best to get the lawyers to draw up the paperwork.
