Prior to signature authentication on any document (power of attorney, consent, family members list, life certificate, declaration of inheritance) the signee’s identity is established on the basis of a valid passport of Bosnia and Herzegovina or a valid identity card / driving licence of Bosnia and Herzegovina, afterwards he/she signs the appropriate document and puts down his/her signature in the Signature Authentication Book, when a proof of paid consular fee is to be presented. However, when the authentication of signature is related to the renunciation from the citizenship of Bosnia and Herzegovina then a valid passport of Bosnia and Herzegovina should be presented!
