Are Trusts Valid From State to State?

State and local laws are an important consideration when planning your estate. If you include a revocable living trust as part of your estate, it should remain valid even if you move to another state. But, even while the trust remains valid, different state laws on issues like marital property and home ownership may require you to make adjustments. Here’s what you need to know.

Talk to a financial advisor about the advantages of trusts for estate planning.

Using Trusts in Estate Planning

Many estate plans use trusts to help shelter estate assets from probate. Not only does avoiding probate help shield private finances from public scrutiny, it can save money and reduce the length of time it takes to settle an estate.

Trusts also provide additional control over the distribution of assets after death. They can help ensure that your assets go to chosen heirs and favorite charities, among other uses.

Moving a Trust to a New State

While different states can take varying approaches to inheritance, they all treat trusts as valid legal contracts. This means you won’t have to draft new trust documents if you move to a new state.

However, while a trust created in one state is valid in any other, state laws regarding property and inheritance can differ in important ways. These differences may require changes to your trust to ensure you preserve its original purpose. As such, it is advisable to review your trust documents after your move.

Estate and inheritance taxes are a good example of how laws can different from one state to another. While the federal estate tax applies regardless of where you live, some states also impose an estate tax or inheritance tax of their their own. Estate taxes are paid out of the estate before assets are distributed. Inheritance taxes, on the other hand, must be paid directly by the beneficiaries.

As of 2026, 12 states and the District of Columbia have an estate tax, and five states levy an inheritance tax. Maryland has both. (Iowa formerly had an inheritance tax but fully repealed it effective January 1, 2025, leaving Kentucky, Maryland, Nebraska, New Jersey and Pennsylvania as the remaining five states with an inheritance tax.) Depending on where you live and the size of your estate, these taxes could affect your estate plan and may call for adjustments to your trust.

Another instance where you may want to update your trust documents is if you purchase a new residence in your new home state. In that scenario, you’ll want to make sure to transfer that property to the trust. If you don’t, your estate will have to go through probate. That can add costs and time to the process of settling your state.

Establishing Domicile in Your New State

The estate and inheritance tax exposure discussed above depends on one specific legal concept: your domicile. This is different from simply where you own a home. While you can have multiple residences across several states, you can have only one domicile at a time. Your domicile is what you consider your permanent home, and it determines which state’s estate tax rules apply when you die.

To establish domicile in a new state, it’s often not enough to just change your driver’s license, register to vote or file a formal declaration of domicile in your new state. States look at the overall pattern of your life. This includes where you spend the majority of your time, where your business or professional activity is based, where your family lives and even where you keep possessions of significant personal value. No single factor decides the outcome; auditors weigh them collectively.

Some states add a second test on top of domicile, called statutory residency. Even someone who has genuinely established domicile elsewhere can still be taxed as a resident of their former state if they maintain a home there and spend more than a set number of days in that state each year, often around 183.

This matters most for anyone moving specifically to reduce estate tax exposure, particularly those who split time between two states. High-tax states have a financial incentive to challenge a claimed move. Audits can happen years after the fact, with the burden of proof falling on the person claiming to have relocated, not the state.

Because domicile determines which state’s estate tax rules ultimately apply to your trust, keeping clear documentation is essential. This includes proof of your move, including time spent in each state, updated ties to your new community and reduced connections to your old one.

States Treat Marital Property Differently

States vary in the way they treat marital property. Most states are common law states that allow for separate ownership of marital property. A handful, however, are community property states, specifically Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington and Wisconsin. In these states, all property that marital partners own is considered equally shared, even if the property is titled in one spouse’s name.

If you are married and relocating to a community property state from a common law state, it can affect your legal authority to bequeath property to anyone other than your spouse. Similar considerations can apply in reverse. When moving from a community property state to a common law state, assets that were considered jointly owned may revert to being treated as separate property. In either case, it’s a good idea to review your trust to see that it will still work as intended.

Additional Trust Planning Considerations

While trusts aren’t likely to require revision after a relocation to a new state, you will likely need to address other parts of your estate plan. For example, you’ll want to make sure notify banks, brokerages or other financial institutions where you have accounts of your change in address. The same goes for insurance policies.

If beneficiaries, such as children, are moving with you, make sure to update their addresses as well. This could be necessary or advisable on trust documents, insurance policies and retirement accounts.

Bottom Line

Additional trust planning considerations may arise when state laws differ.

A trust drawn up in one state is valid in any other state. But some differences between jurisdictions may make it advisable to review and possibly amend your trust. This is especially true if you move to another state. Married people who move from a common law state to a community property state, or vice versa, will want to find out whether differences in the treatment of marital property affect their trust. If so, they will need to check their trust and update it accordingly.
