Well, a blanket consent to adoption won't work in Utah (my experience at least). The consent needs to be one that specifically names the person who's going to adopt the children.
As for the sources for adoption paperwork and such - see my message above as well as the following link:
http://www.law2.byu.edu/law_library/...es/guide5.html this was the starting point for me.
Specifically, the Domestic Relations Manual which is in the reserve section at the BYU law library is a great reference.
Specific to step parent adoptions, there is an article from the Utah Law Review from March of 1994. It starts on page 16 and Jeannine P. Timothy is the author.
Good luck on your quest and come back with and upate and/or questions.
