A Declaration of Domicile is a legal document that identifies your principal home in Florida, with tax and asset protection benefits. 'Domicile' generally refers to where you live – your residence that you intend to keep for the foreseeable future.A domicile is your "true home," which you use as your base. Domicile is the place you intend to make your permanent home, the place to which you intend to return if you are temporarily residing in another state. "Residence" means the place where you are actually living. By itself, residence usually has little or no legal significance.
