Expedite due to personal circumstances

Hi team
I am about to put through a property registration on behalf of the executor of my recently deceased mother. The property has been left to me however it was never registered.
I would like to check if it's possible to have the registration request expedited because the executor is very elderly and I am concerned he may not be capable of assisting in the request if we have to wait up until 19 months.
I understand that this is probably an unusual request, but I would like to check whether this will be possible.
thanks 

Hi Andrew - I would suggest making the request after the actual application has been submitted and acknowledged. The support team will then consider and respond as appropriate

Hi Adam
Thanks for the response. I'll check after I've submitted the request.
regards
Andy
