Short answer: If you work remotely, travel often, or split time between two or more states, your legal home for estate planning purposes is not automatically wherever you happen to be living when you sign your documents. Courts look at your domicile, the place you intend as your permanent home, to decide which state’s law governs your will or trust, which probate court has authority over your estate, and whether your power of attorney and health care documents will actually work when someone needs to use them. A plan that made sense in the state where you signed it can stop working cleanly once you relocate.
What does “legal domicile” mean, and why does it control my estate plan?
Domicile is not the same as wherever you are physically located today. It is the place you treat as your permanent home, the one you intend to return to even when you are traveling or working elsewhere. Courts and probate clerks use domicile, not your current mailing address or the state where you happen to be renting, to decide which state’s probate court has authority over your estate when you die and which state’s law is used to interpret your will or trust.
For someone who lives in one place year round, domicile is obvious. For a remote worker who splits time between a rental in California, a family home in another state, and stretches of time abroad, it is not obvious at all. That ambiguity is exactly what creates problems for the family sorting things out after a death or a period of incapacity.
What happens if more than one state could claim to be my domicile?
When two states each have a plausible claim to being your legal home, more than one probate court can potentially assert jurisdiction over your estate. That does not mean two courts will fight over your case as a matter of course, but it does mean your family may need to spend time and money establishing which state actually has authority before they can move forward with anything else.
An unclear domicile also complicates which state’s law a court applies to interpret your documents, and it can affect how your assets are handled for tax purposes. None of that gets resolved by having a will or trust that looks complete on paper. It gets resolved by having a plan that is built around a clearly established, provable domicile in the first place.
Will my will, trust, or power of attorney still work after I move?
Usually, yes, in the sense that a document validly signed in one state generally remains legally valid after you move to another. But valid is not the same as effective. States differ on signing and witnessing formalities, on how much authority an agent under a power of attorney actually has, and on how a trustee is expected to act. A document that is technically enforceable can still fail to do what you actually need it to do in your new location, especially if a bank, hospital, or title company there is unfamiliar with the version you are holding.
This is the problem I see most often with mobile clients. A solid plan gets built once, in one state, and then never gets revisited after a move. Nobody circles back to confirm the named agents still have the authority they need, or that beneficiary designations and property titling still line up with the rest of the plan.
Does living or working outside the United States change anything?
It can. Once a foreign country enters the picture, whether as a place you live part of the year or as the location of a bank account or property, you add a second layer of law on top of the domicile question: which country’s rules apply to that particular asset, and whether your U.S. documents will even be recognized there. A U.S. power of attorney is not automatically honored by a foreign bank or hospital, and a foreign account is not automatically covered by instructions written for U.S. institutions. This is fact-specific enough for each family that it needs a direct conversation rather than a general rule.
What should a mobile family’s estate plan actually cover?
A plan built for someone who moves often needs to do a few things a stationary plan does not. It needs to confirm and document your actual domicile rather than assume it. It needs documents drafted to work under that state’s law, with agents who have clear authority to act no matter where you are when something happens. And it needs a periodic review, because a plan that was accurate the year you signed it can drift out of alignment with your life within a few years of relocations.
A funded revocable living trust can help here, since a trust generally travels with you more cleanly than a will alone, but only if it is actually funded, meaning your accounts and property are properly retitled into it. A trust that exists on paper but was never funded does not avoid the same jurisdictional questions a will would raise.
What to do next
If you split time between states, work remotely, or spend significant time outside the country, do not assume your existing estate plan still fits your life. Pull your will, trust, and power of attorney documents and check the date you signed them against every move you have made since. If those dates do not line up, or if you are not sure which state a court would call your domicile, that is worth a conversation with a California estate planning attorney before it becomes your family’s problem instead of yours.
