College kids are a prime example. People working remote jobs away from family are another. It is not illegal to own multiple domiciles (as long as your loan papers match primary residence seeing that is being weaponized now), and live back and forth between them.
IANAL but I think domicile is only one place by definition. You can have multiple residences. Your domicile might be required to be the place you spend the most time at. College students would be a common counter-example, if they can live at college for 9+ months and still be registered at their parent’s home or such.
