Natalie - we don't have an application pending against that title so nothing has been expedited as yet.
Once an application is submitted it can then be expedited as you state. Processing generally starts within 10 days but everything then hinges on it being in order and wider checks not being needed. Expedition is not always a 'magic wand' solution.
Suggest you ask whoever is submitting the application to confirm the title number and our case (ABR) reference as well and we can check again
I note that there is a charging order protected on the register by way of a form K restriction and I assume that's the restriction/charge you are referring to. If it is you may wish to refer the conveyancer to section 4 of our PG 76 for guidance on how such a restriction might be overreached when a sale is being completed in case it helps progress matters -
