Late appeal

It’s a question of whether the appeal was validly lodged and then has gotten lost in the system or whether it never made it to FtT.

Did the client receive an acknowledgment letter or was there any call to HMCTS to confirm receipt?

In principle the solution is to have the file looked at by a judge or registrar to rule on whether it was validly lodged at the time.

This might help

In these circumstances I routinely submit a further appeal and explain why it is not late. Provide a copy of the original appeal and the case note and a copy of the email to our print room to show that all was as it ought to have been at our end if needed. Done one last year and it happened the appeal was accepted without any further issues and wholly accepted as having been made in time.

Nowadays you have to be trying pretty hard to not get so called late appeals admitted.
