Moving to a new state requires revisiting your estate planning.
Each state offers unique benefits, challenges, and adventures.
Those who relocate elsewhere in the United States will find that estate planning laws vary.
Each state has its own laws governing taxes, last wills and trusts, guardianships, advance directives, and property ownership.
Generally, the laws of most states provide that legal documents properly prepared and executed in another state are valid in the state where presented for use.
Although your estate planning documents from another state may still be valid, they may no longer function according to their original design and purpose.
Reviewing and updating estate planning documents should be prioritized after relocating across the country or even just across state lines.

If your new state of residence is Kansas or Missouri, Harvest Law KC can support your estate planning needs in either state.
State laws govern estate administration.
Although assets may be subject to federal taxes after the death of the original owner, the specific rules around probate, intestacy, state inheritance or estate taxes, and incapacity are decided at the state level.
People who move to a different state risk unintended consequences if they do not take the necessary steps to align their estate planning documents with the laws of their new state.
What types of differences may need to be addressed through an estate plan review?
People must ensure their plan complies with formal signing requirements, the elective share rules for spouses, probate procedures, and the new state's property classification and division rules.
Neglecting to review and update estate planning documents can have devastating consequences.
What types of issues may arise?
New laws and old documents may conflict rather than work together.
Probate may be more expensive and take longer to settle the estate.
If a new state imposes more stringent requirements for guardian designations, issues may arise when this role is needed.
Healthcare providers and financial institutions may hesitate or refuse to honor powers of attorney or advance directives.
Yikes!
Unless one is proactive, these distinctions may only be discovered in the midst of a crisis when it is too late to address them.
What documents should be reviewed after a move to a new state?
Last Wills
States have different requirements for notarizing and witnessing last wills.
Even if your last will is still legally valid, it may not be recognized by the new probate courts.
Trusts
Because trusts are not subject to probate courts, they are generally more effective from state to state than last will and testaments.
Even so, rules governing trustees, real estate, and tax treatment can vary.
Amendments to a trust can address these specific distinctions.
Powers of Attorney & Advance Directives
Financial and healthcare institutions may be hesitant to accept forms from other states.
By updating advance directives and powers of attorney, these institutions will be more willing to accept the documents.
Property and Beneficiary Designations
Moving to a new state often involves the buying and selling of real estate.
This necessarily involves updates to property titles.
If your estate plan also includes a revocable living trust, you may choose to retitle your property to fund the trust.
Any insurance policies or retirement accounts should also be reviewed to ensure they align with changes to your estate planning documents.
Although moving to a new location brings new experiences and possibilities, estate planning should not be overlooked amid the excitement.
Even if you are just moving from Kansas to Missouri or Missouri to Kansas, you will need an experienced estate planning attorney to review and update your plans.
