Under the common law, if two spouses died close to the same time, it had to be determined by medical evidence which person actually died first, even if the deaths were only a few moments apart. The estate of the spouse that died first would pass to the second spouse, and then the second spouse's estate (which is combined with the first spouse's estate) would pass to the second spouse's heirs. This scenario required two probates!
However, it is often impractical or even impossible to determine the order of two deaths with any certainty.
Enter the revised Uniform Simultaneous Death Act, which Minnesota incorporated into its Probate Code in the 1990s. Under this Act, if two spouses die within 120 hours of one another, and there is no Will, the law treats each spouse as having predeceased the other. Therefore, the law views it as a simultaneous death, even if the two spouses died up to 120 hours apart. Then, the probate court applies the laws of intestacy to determine which beneficiaries will share in the two spouses' combined estate.
Having a poorly-drafted Will isn't always helpful, and in fact can complicate things. If each spouse's Will names the other spouse as sole beneficiary, without clearly naming contingent beneficiaries, problems can arise. The Will does not give instructions as to how the combined estate is divided by the couple's descendants, and the probate court must apply the laws of intestacy to distribute estate assets.
Here's where things can get even more complicated.
Suppose the couple have a blended family, i.e., each spouse has children from previous relationships. Each spouse has a Will, favoring their respective children. Perhaps these Wills were executed by each spouse before they were married, and they never executed new Wills after they were married. If both spouses are deemed to have died simultaneously under the law, whose children receive shares of the estate? The outcome is uncertain.
For example:
Adam and Betty get married. Adam has a son from a previous relationship, and Betty has two daughters. Adam and Betty each have Wills executed before they got married, and they never got around to getting new Wills.
Then, a terrible tragedy strikes. Betty dies right away, but Adam lives 3 more days. Under the law, the probate court treats Adam as having died before Betty, and Betty as having died before Adam. Simultaneous deaths.
Whose children receive shares of Adam and Betty's combined estate? Again, an uncertain outcome. There may also be uncertainty for any gifts to individuals outside the family, charitable donations, etc., if the two spouses' Wills differ on those issues.
To prevent that, Adam and Betty could have had Wills drafted that names one of them to have survived the other, and the Will of the presumed "surviving" spouse would govern as to contingent beneficiaries. There may be some tax benefit in doing this, as well.

If you do not have an estate plan, or your existing plan is dated or you're just not sure, it would be wise to seek a qualified Minnesota estate planning attorney.
