As a general rule, a will should remain valid even after moving to a new state. However, states have their own laws on what makes a will valid and legally binding. These specific legal provisions can make an out-of-state will invalid, depending on the laws in each state. Even if the will is valid in the new state, certain parts of the will may become void or need to be changed.
For example, Florida requires that the personal representative be related by blood or a degree of marriage or, failing this, be a Florida resident. Florida doesn’t recognize holographic (handwritten) or nuncupative (oral) wills but most states do.
