If you've moved to a new state since you prepared your estate plan, your will, powers of attorney, trust, and living will are probably still valid in your new state. But you still have valid reasons to update your estate plan.Your new state may have different laws about probate and estate taxes that you'll want to take into account. Financial institutions and healthcare providers may more readily accept an in-state power of attorney than an unfamiliar out-of-state one. And the people you named as executor and power of attorney may have a hard time filling those roles if they now live far away.
