The easiest way to become an official Florida resident is to file a declaration of domicile. Declaring Florida Domicile is a "question of intent". The courts have ruled that your heart is where your treasure lies. Many households have more than one residence, sometimes more than two, so the matter of "intent" is very important. The fact that one has lived in Florida continuously for six months is not always true.
The Declaration of Domicile which states that you reside at a given address, is notarized and filed with the County Clerk of the Circuit Court of residence. No time constraint is required before one can legally be declared a resident.
For more information, contact the Sarasota County Clerk of Circuit Court, 2000 Main Street, Sarasota, FL. Telephone (941) 362-4066, or go to www.floridadomicile.com.
Interesting: "question of intent" and "your heart is where your treasure lies"
I heard on FNC a couple of weeks ago that Florida had (I think)~40,000 voters that were registered in New York and Florida. That is a felony and they were exploring what it would take to prosecute. Haven't heard a word since.
