Identification

I am completing the ID3 and my query relates to the list of acceptable verifyers.   The Land Registry form I have does not include solicitors and licensed conveyancers on the list. 
This is rather strange
Can you confirm this please

Barbara - if you want to have a conveyancer/solicitor verify your identity then they would do that using form ID1. Form ID3 is an alternative form for others to verify an identity - Practice guide 67: evidence of identity - GOV.UK
