Domicile is an important estate-planning concept for people who divide their time between states. It generally refers to the place you regard as your permanent legal home. You can have several residences, while domicile usually identifies one legal home for the question being considered.
Intent and conduct both matter
Determining domicile involves more than reading a mailing address. Where you actually live, your connections to each place, and evidence of your intention can all be relevant. A Florida declaration of domicile can document the intention, but filing the declaration does not make every other fact irrelevant.
Tax residency is a related but separate issue. Another state may apply its own residency or day-count rules for income-tax purposes even when you regard Florida as your domicile. A move should therefore be discussed with the appropriate tax advisers as well as estate-planning counsel.
Review the effect on your estate plan
Domicile can affect the principal administration of an estate and the rights of a surviving spouse or other family members. Real property also brings in the law of the state where it is located. A Florida domiciliary’s out-of-state real estate, for example, may require attention to that state’s title and administration rules.
A will properly executed in another state may be recognized in Florida, subject to Florida’s recognition requirements and exceptions. Recognition of the document’s execution does not necessarily mean that every provision has the same effect under the new state’s law. Homestead restrictions and spousal rights are examples of issues that need a separate review.
Coordinate instead of collecting conflicting documents
People who live in two states sometimes accumulate several wills, powers of attorney, or health care directives. Those documents should be reviewed together to avoid unintended revocations or inconsistent instructions.
The review should also cover deeds, trust funding, account ownership, beneficiary designations, and the eligibility of the people named to act. A move can affect the practical usefulness of an appointment even when the document remains legally valid.
We can help evaluate the Florida portion of your estate plan and coordinate with advisers in other states. The goal is a coherent arrangement based on your actual circumstances, rather than an assumption that one declaration resolves every legal and tax issue.
