If you have a court order that you want to apply to change, the same basic rules around jurisdiction apply as if you have never had an order before. Changing an order is also called 'varying' an order.
Where you file your court application will depend on what issue you are applying to deal with, and where you, the other party, and perhaps the children, live. It may also depend on whether or not you were divorced from the other party. The Supreme Court (Family Division) and the Family Court operate using different sets of court rules, and may view jurisdiction differently.
Note that if you have a final order dealing with property, pensions, or debts, you probably cannot change that order. Usually, once these issues are finalized in an order, you cannot change them afterward. If you have an order for property, pensions, or debts that you want to try to have changed, you should speak to a lawyer for advice.
For a variation application - an application to change a court order - you must be able to show that there has been a material change in circumstances.
