It is important for any agreement reached to be properly drawn up. If the agreement is reached within the context of divorce proceedings, the appropriate method would be for a consent order of the court to be drawn up, and lodged with the court for approval by a Judge. Once approved by the court it becomes binding upon both parties and can only be challenged in very rare and limited circumstances. If the parties are not considering divorce proceedings at this moment in time, the appropriate way to proceed would be to draw up a separation agreement, which is in effect a contract between the parties.
