€10 solicitors fee
The €10 fee referred to in this post is not a fee for legal advice, but is the statutory fee for witnessing an affidavit - i.e. where the solicitor fulfils the functions of a Commissioner for Oaths. There is a section of the Form A1 where you are swearing that the statutory requirements for incorporation have been met. Your affidavit must be witnessed by a Commissioner for Oaths.
All practising solicitors are qualified to attest an affidavit; in addition, there are some Commissioners who are not solicitors - I don't know how one gets appointed to such a position, but it's a modest little earner for those that do it.
