If your family winters in Florida or Arizona but keeps roots in New York, you live a wonderful dual-state life — and a slightly complicated legal one. The good news is that with a little planning, you can keep things simple and keep your loved ones from untangling a cross-border mess later. This guide is written for New York snowbirds who want peace of mind on both sides of the journey.
Why Your Domicile Matters Most
You can have many residences, but only one domicile — the state you consider your true, permanent home. Domicile drives where your estate is administered, which state’s intestacy rules apply, and whether you owe state estate tax. New York’s estate tax for 2026 uses an exclusion of $7,350,000, with a notorious “cliff”: estates exceeding 105% of that amount ($7,717,500) lose the exemption entirely and are taxed on the whole estate. Florida, by contrast, has no state estate tax. For larger estates, clarifying domicile is not a minor detail — it can mean a meaningful difference for your heirs.
Making Your New York Documents Travel With You
A will signed in New York is valid if it meets New York’s execution rules under EPTL §3-2.1 — signed by you and witnessed by two people. Most states honor an out-of-state will that was properly executed where you made it, so a New York will generally follows you to Florida. Still, your durable power of attorney (governed in New York by GOL §5-1513) and your health care proxy (PHL Article 29-C) are the documents most likely to be questioned at a hospital or bank away from home. Many dual-state families choose to execute a set of documents for each state so a Florida ER or bank recognizes them without hesitation.
Probate in Two Places
When a New York resident passes, the will is offered for probate in the Surrogate’s Court of their home county under New York’s SCPA. But if you own real estate in another state — a Florida condo, say — your family may face a second, “ancillary” probate there. A revocable living trust under EPTL Article 7 is a popular fix for snowbirds: property titled in the trust passes outside probate in both states. Remember, a revocable trust avoids probate but does not, by itself, save estate tax.
Keeping Beneficiaries and Titles in Sync
Snowbirds often accumulate accounts in two states — a longtime New York bank, a newer Florida brokerage. Beneficiary designations on retirement accounts and life insurance pass outside your will entirely, so a stale beneficiary form can quietly override your carefully drafted plan. Review titles and designations whenever you open accounts in your second state.
A Plan That Follows the Sun
The heart of snowbird planning is consistency: one clear domicile, documents both states will honor, and titling that avoids surprise probate. Done right, it lets your family focus on you, not paperwork, no matter where you are when they’re needed most.
A note before you act: dual-state estate planning turns on the fine print of two states’ laws and your specific assets. Speak with a qualified New York estate planning attorney to confirm your domicile strategy and make sure your documents work wherever life takes you.
