If the other party is in agreement, an order may be entered nunc pro tunc. This would save more money in avoiding a potentially contested action.
If there is no agreement, you would file a motion explaining the problem and requesting appropriare relief. If the action is in Kent, you would need to give 14 days notice of the hearing to the other party.
I would suggest that you contact a family law attorney regarding the procedures and get a 30 minute free consultation. You may contact my office and I will be happy to discuss the issue with you right away.
