Whether you’re changing jobs, retiring, or just wanting to start fresh in a new state, you’ll want to keep your estate plan current. Differences in state law can impact your existing wills, trusts, and advance directives, and what’s valid in your old jurisdiction may need adjustments to stay valid in your new home.
How Moving Out of State Affects a Will
The U.S. Constitution’s Full Faith and Credit Clause requires states to respect other states’ public acts, records, and judicial proceedings. This means that wills that are proper in one state are generally honored in others, so long as the will is valid under the originating state’s law. However, valid is not the same as optimal.
Above all, you must ensure your will’s structure works well with your new state’s probate process. Oklahoma specifically requires that wills be in writing, with signatures from two witnesses or one witness with a licensed notary. You can also create a holographic will that you handwrite, date, and sign without any witnesses necessary.
If you’re moving to Oklahoma from another state, your lawyer may recommend changes to how you distribute your estate. Some states have differing rules about what surviving spouses can claim or community property laws that Oklahoma doesn’t recognize.
How Moving Out of State Affects a Trust
Trusts are governed by the state law named in the trust document. This is sometimes called the “situs” of the trust.
For a revocable trust, you can often change the situs to your new state without problems. From there, it will be bound by the laws of that state. Irrevocable trusts may be harder to move depending on the specific state law involved and the text of the trust document.
If you’re moving to Oklahoma, ask your lawyer about how the Trust Reform Act of 2024 affects your estate plan. This law allows directed trusts and makes other changes that could offer you more flexibility.
How Moving Out of State Affects Power of Attorney
In 2021, Oklahoma became one of the latest states to enact the provisions in the Uniform Power of Attorney Act (UPOAA). Each UPOAA state has the exact same power of attorney laws and procedures. If you’re moving to Oklahoma from another UPOAA state, your power of attorney will likely be recognized in your new state as long as it meets the legal standards.
If you’re moving out of Oklahoma to a state that has not adopted the UPOAA, your power of attorney could still be valid so long as it met the legal requirements when you created it. Your legal team in your new state can explain any necessary updates to keep the directive valid.
Estate Tax Considerations When Moving to or From Oklahoma
Since 2010, Oklahoma residents have not had to pay estate tax or inheritance tax at the state level. However, federal estate taxes still apply if the value of your estate exceeds the statutory threshold, currently $13.99 million in 2025.
If you’re moving to Oklahoma, your estate planning could be much simpler thanks to the lower tax liability. However, if you’re leaving Oklahoma for a state that does levy inheritance and estate taxes, you may want to update your estate plan to limit potential liability.
