In individual cases, information may be provided and consent given in a non‑written form if:
the person concerned, for physical or cognitive reasons, cannot read or cannot write; and
the investigator furnishes proof of the provision of information and consent, specifically by means of written confirmation by witnesses, or by a recording of verbal consent.
In individual cases, the requirement to provide information in written form may be waived if:
this could only be implemented with disproportionate effort, given the language skills of the person concerned; and
an independent qualified translator is called in to provide oral information and gives written confirmation thereof.
