Your domicile, or legal residence, is your true home or main residence. You may have multiple residences at one time, but only 1 domicile.Domicile or legal home is defined as consisting of three elements: (1) actual physical presence (2) at a fixed dwelling. For nonresident period, you do not have MA source income. A person's domicile is usually the place where they maintain their most important family, social, economic, political and religious ties. Use our Affidavit of Domicile form to verify the last home address of a deceased person to speed up the inheritance process. Simply put, your domicile is your home—the state you consider your permanent place of residence. Domicile is intended to be permanent rather than temporary, whereas residence means living in a particular locality and requires mere physical presence.
