Generally, a person's "domicile" is his or her primary legal residence. Establishing Nevada residency can provide significant tax benefits, but you need to make sure you do it right when selecting Nevada as your domicile state.Domicile is intended to be permanent rather than temporary, whereas residence means living in a particular locality and requires mere physical presence. No, the domestic partnerships in Nevada will not be automatically converted to marriages. Although a domicile may change from time to time, a person has only one domicile, or residence, at any point in their life, no matter what their circumstances.
