They passed a law making it so only married people can adopt - I don't know what Utah's state constitution would say about it like AK's did - but hopefully the same can be done there.
http://gaylife.about.com/od/gayparentingadoption/a/gaycoupleadopt.htmFlorida Prohibits single and joint gay adoption.
Missouri Single GLBT and joint adoption unclear. Second-parent adoption unclear.
Nebraska Single GLBT adoption unclear. Does not clearly prohibit joint gay adoption. Prohibits second-parent adoption.
Utah Permits single GLBT adoption. Joint adoption prohibited. Second-parent adoption unclear.
the above link is wrong for Utah:
"Utah and Florida are among the states that historically imposed more stringent restrictions of LGBT adoption. Utah prohibits adoption by "a person who is cohabiting in a relationship that is not a legally valid and binding marriage,"<34> making it legal for single people to adopt, regardless of sexual orientation, so long as they are not co-habitating in non-marital relationships."
