Moving from Iceland
Transfers of legal domicile from Iceland must be registered within 7 days.
Transfer of legal domicile between the Nordic countries must always be registered in person in the requisite registration office in the country to which you are moving.
The same rules apply to the transfer of legal domicile to countries other than the Nordic countries as apply to changes to legal domicile within Iceland.
Note that if one partner in a registered cohabitation moves abroad, the cohabitation is deregistered in the National Registry, with the attendant legal consequences. If, for example, the parties have children together, the cohabitation may not be deregistered until custody has been settled.
If the party that did not move from Iceland later moves abroad to the former cohabiting partner, the persons in questions are not registered as cohabiting unless they submit a request to that effect using the appropriate form.
Foreign nationals have to register a change of address using a separate form despite having previously been allocated an ID No., see: New registration of foreign nationals.
