Hi, we looked into this and because you only need a solicitors stamp and business card, the solicitor can do this for you-not a notary. So therefore, we got quoted £5 per affadavit and £2 per attachment. We rung loads of places who quoted us £100+ but that is if a notary was to do it. Take your drawn up copy of your affadavit to the solicitor. Make an appt first though.
