The use of WhatsApp without the declaration of consent from every person in the user’s address book directory is deemed to be inadmissible in a recent decision by the family law department of a German lower federal court (AG Bad Hersfeld, 15.05.2017 – F 120/17 EASO).

The court held that the mother of an 11-year-old boy had to ensure and constantly control that all of her son’s phone contacts had given their consent to the transfer of their contact data to WhatsApp.
