That said, there are state-specific rules for the drafting and execution of Wills, and the probate process, that can vary from state to state. While all 50 states have adopted the Uniform Probate Code, each state has the discretion to tweak the Code language as it sees fit. These variations may impact certain provisions in your Will, and affect how the probate process may apply to your Will.
Different states may require different elements for a Will to be valid. Many states require that the Will be typed or printed. Other states allow hand-written Wills ("holographic" Wills). There may be variations as to notarizing a Will, and who must witness the signing.
Estate and inheritance taxes may differ from state to state.
Property laws can vary from state to state, and some provisions in a Will executed in one state may not be valid in some other states. In the majority of states, common law applies, wherein a spouse that acquires property solely and completely owns that property. However, nine states apply community property law. In this case, all property acquired by either spouse is owned jointly by both spouses. If you have a Will executed in a common law state and you move to a community property state (or vice versa), there are issues that may arise after you die.
Moving is exciting, but it can be stressful and filled with lots of tasks. When relocating to a new state, don't take chances with your estate plan. Seek a qualified estate planning attorney in your new state and have them review your existing Will. In addition, it would also be prudent for you to have the new attorney look over your Health Care Directive and Power of Attorney.
