Ask an Property Solicitor. Get an Answer ASAP.
I see what you mean. Normally to vary an order though it is done with the N244. An N161 appeal questions a judge's decision. It would be worth speaking to the court and asking them whether the N244 is the best way forwards. I do not know what the judge's comments were at the time so the court staff should be able to confirm for sure the correct method to use.
Let me know if you want me to find the contact number for the court.
