There is a major case in Houston where a fire or police man was killed. His widow laid claim to part of the estate and death benefits, but the first wife on behalf of the minor children from the first marriage is contesting the second marriage.
It seems the 2nd wife had a sex change operation to become female and such a marriage is apparently not legal in Texas or else the guy was not aware his wife was sexually altered and therefore the marriage is invalid. I've forgotten the details, but it should be interesting to follow in the news.
