Urgent Reply pls help about referee ?

Hi

I am applying next week for Naturalisation.

I took two referee signatures.
1) Accountant, British passport holder.
2) Solicitor, British passport holder.

but I can only double check with Accountant's Passport. His Name, DOB and etc,....
I could not check with solicitor's passport as he said remember his detials. (why i am worry)
if any thing goes wrong with his details, like DOB or PP No. what he provide will it effect my application.

for question 5.2 how you know the applicant,?
Solicitor has wriiten me as Client.
I have done my hsmp case with him in 2007. this is how he knows me.
but now he is not representing my case as I am using NCS.
