The United Kingdom contains three jurisdictions: England and Wales; Scotland; and Northern Ireland. All UK jurisdictions distinguish between domicile of origin (decided by the domicile of their father, or if parents unmarried their mother), domicile of choice (when a person has exercised a legal option to change their domicile as can be done when attaining majority) and domicile of dependence (applicable to those legally dependent on another such as some incapable persons, children, or women married before 1974) but in general only one place can be a person's domicile at any one time thus preventing the creation of differing simultaneous domiciles for different purposes; the three types of domicile can enable a voluntary change when a person reaches a relevant age. If a domicile of choice lapses and is not replaced the domicile of origin reasserts itself. The concept of domicile is not rooted in statute, thus the basic matter of an individual's domicile is not decided by any single statute but rather by case law in combination with applicable international law and statutes following in accord.
