Moving to s new state can affect how your Estate Plan will work. Just like with having children and changes to your finances...when moving to a new state you need to review your Estate Plan.
If one thing is certain, things change. The way your family looks, the value of your assets, tax law, inheritance laws, etc.
Generally when any of these things happen an estate plan update may be necessary.
Moving from one state to another generally means that the tax laws and inheritance laws are different. Therefore, if you move to a new state you should at the very least review your estate plan to see if an update is necessary...really you should have an experienced estate planning attorney do that review for you.
