Thank you for your question
My name is Clare
I shall do my best to help you but I need some further information first
What was the exact wording of the Order?
Did either of you have legal advice?
Did the solicitor you instructed review the one that you actually signed with you?
In that case there is a good chance that you could, if necessary, have the Consent Order se aside on the basis that it was signed by you in good faith on the basis of the agreement that you believed had been made.
From everything that you have said it is clear that your ex did this deliberately and is hoping to hide behind the Order.
I suggest that you inform her that unless the matter is resolved you will indeed apply back to the court on the basis of her lack of honest disclosure - and claim the costs from her
I hope that this is of assistance - please ask if you need some further details
Sadly we are not able to have any direct contact outside of this forum.
however I can draft the letter if you wish as a separate service - but not until Sunday
I am afraid that it would be a letter from you rather than from me
I think you have an excellent chance if success if you go back to court
