For the purposes of this chapter, the term "domicile" means the present fixed place of residence of an individual to which he or she returns following temporary absences and at which he or she intends to reside indefinitely.
No person may have more than one domicile simultaneously.
Domicile cannot be established initially in the District of Columbia unless:
Once domicile is established in the District of Columbia, actual residence in the District is not required.
Once a domicile has been established, a person retains that domicile unless the evidence affirmatively shows that the domicile has been abandoned.
