Therefore, if you intend to permanently reside in the new state, it is important that you clearly change your domicile by registering to vote, getting a new driver's license and filing state and local income tax returns in the new jurisdiction. After establishing your domicile and settling into your new residence, it is a good idea to take your existing estate planning documents to a qualified attorney in that jurisdiction to review and update them. The new state may have different rules with respect to these documents, especially those that pertain to the disposition of property. Your revised estate plan should take into account any special provisions of that state's laws. If you own real estate in a state or states other than your new principal residence, you may also wish to consider a Revocable Living Trust.
Most states have common law property rules but more and more are adopting community property laws.
The concept of community property is that each spouse generally owns one-half of any property acquired during the marriage. If you move from one common law property jurisdiction to another, there may be little to do with respect to your property interests. If you move from a community property jurisdiction to a common law jurisdiction, there may be advantages, including income tax advantages, to maintaining community property. This may require that you prepare an agreement between the spouses. Likewise, if either you or your spouse is not a United States citizen, special estate planning rules apply and require your attention.
