If a notification has been submitted with regard to a person whose registered domicile is unclear or who has no registered domicile, and subsequently their registered domicile is clarified or they come to have a registered domicile, the notifying person or the party to the event under notification must make the event under notification clear and file a new notification to that effect with the mayor of a municipality who accepted the first notification, within ten days from the day on which they came to know that fact.
