An appeal has to be lodged within 3 weeks of the date of the order.
I recall a matter where a party failed to comply and applied to vary the order a few months after it was made. The Judge was highly critical of the application, described it as \"an appeal by the back door\" and dismissed it - ordering costs against the applicant.
You should write to state the breach of the order and request that there should be compliance immediately or you will apply to the court and seek your costs of the application if there is no response within a specified period (14 days perhaps?)
You can then make the application to the court and rely upon your letter to claim your costs back.
