As Domicile is one of the connecting factors ordinarily used in common law legal systems, a person can never be left without a domicile and a domicile is fixed for everyone at birth. Generally domicile can be divided into domicile or origin, domicile of choice, and domicile by operation of law (also known as domicile of dependency). When determining the domicile of an individual, it has been established that a court should apply its own law and understanding of what domicile is (lex fori).
