Thanks. I signed some last year with no problems but have received a letter today asking for my employer & qualification details for a form I recently counter-signed.. Will just assume that it is a random check.
At least the passport forms give you some indication of who can sign. I've posted my application for my teaching pension today ('cos I'll be 60 next month) which had an 'attestation' to be signed by an 'independent third party' but without the slightest indication of who was qualified to do the job! (I played safe and paid a fiver for a solicitor to do it).
