Well, you can have a Legal declaration of marriage made, anyway. http://www.deseretnews.com/article/865617346/Utah-Supreme-Court-reinstates-Ogden-womans-marriage-to-dead-man.html SALT LAKE CITY — Janetta Gardiner lived with and cared for Jacob Kenneth Vanderwerff for three years before he died of cancer at age 78 in April 2010 — and legally married him a month later. Vanderwerff's cousins challenged a 2nd District Court's granting of a declaration of unsolemnized marriage, eventually getting it thrown out. But the Utah Supreme Court reinstated the marriage Tuesday, ruling that the relatives did not have legal standing to intervene in the matter. Here's the part that I find interesting. I've been saying things like this could happen... "Had the court said cousins have standing to intervene in marriage petitions, well, my goodness. That means if cousins have standing, so do parents, so do children," he said. "Suppose somebody doesn't like a same-sex couple getting married. You could have people coming out of the woodwork petitioning the court, arguing against this marriage." Somehow, I don't see that as the same thing as arguing about marrying a dead person.
