A financial agreement can actually be an order

If you attend a Financial Dispute Resolution (FDR) appointment at the court and reach agreement on financial settlement, if the district judge approves the agreement but the drafting of the order is left until later, neither of you will be able to change your mind.  The court will treat the order as having been made at the point at which the district judge approves the agreement.  It is an ‘unperfected order’, but it is nonetheless an order.  It becomes ‘perfected’ once the order has been drafted and approved by the district judge.

So, if you find yourself in this situation, before agreeing to a financial settlement make sure you are prepared to be bound by it.
