A Will that is properly made and properly executed in your former state of residence, that would be valid under the laws of your former state, will almost invariably be regarded as valid by the laws of your new state. However, as the laws of all states differ, if you move it makes sense to have your Will reviewed by a lawyer in your new state.
For example, sometimes the new state has different processes to “prove” the Will. The new state may permit probate matters to be handled on a less formal and less expensive basis, simply by adding to the Will reference to certain specific statutory provisions in the new state’s laws.
Occasionally complications arise because different states have different classifications of property. For example, if your Will was executed in a state that does not have a community property system and you move to one of the 9 community property states, you may wish to get in touch with an attorney to determine whether your Will should be redrafted to achieve your intended result.
