(a) “Domicile” is the one location with which for legal purposes a person is considered to have the most settled and permanent connection, the place where he intends to remain, and to which, whenever he is absent, he has the intention of returning, but which the law may also assign to him constructively.
In California, you are considered a resident if you meet one of the following criteria: You are in California for other than a temporary or transitory purpose. You are domiciled in California, meaning California is your permanent home, but you are temporarily located elsewhere.
Simply, a person's domicile is the place where they have their most settled legal connection. Under RTC 17014(c), an individual may only claim one domicile at a time. This follows the logic that you can only be the most settled and have a permanent connection to one place.
A "principal residence" or "principal place of residence" is considered to be equivalent to domicile, that place where a person has his or her true, fixed, and permanent home and to which that individual has the intention of returning to, whenever absent.
You're a resident if either apply: Present in California for other than a temporary or transitory purpose. Domiciled in California, but outside California for a temporary or transitory purpose.
To meet these requirements, you must be continuously physically present in California for more than one year (366 days) immediately prior to the residence determination date (generally the first day of classes) and intend to make California your home permanently.
A resident is any individual who meets any of the following: • Present in California for other than a temporary or transitory purpose. Domiciled in California, but outside California for a temporary or transitory purpose. See Section L, Meaning of Domicile. A nonresident is any individual who is not a resident.
