In the field of conflict of laws, habitual residence is the standard used to determine the law which should be applied to determine a given legal dispute. It can be contrasted with the law on domicile, traditionally used in common law jurisdictions to do the same thing. Habitual residence is less demanding than domicile, and the focus is more on past experience rather than future intention. There is normally only one habitual residence where the individual usually resides and routinely returns to after visiting other places. It is the geographical place considered "home" for a reasonably significant period of time.
