(1) If referral is made to the law of a State of which a person is a national and where this person is a bi- or multinational, the law applicable shall be that of the State with which the person has the closest connection, especially through his or her habitual residence or through the course of his or her life. If such person is also a German national, that legal status shall prevail.
(2) If a person is stateless or if his nationality cannot be identified, the law of that State is applicable in which the person has his or her habitual residence or, in the absence thereof, his or her residence.
(3) If referral is made to the law of a State in which a person has his or her residence or habitual residence and a person without or under restricted capacity to contract changes his or her residence without the consent of his or her legal representative, the application of another law does not ensue from this change alone.
