Did a little more digging to lean about terminology in Utah divorces. Here is some information I found to be helpful:
http://utahlegaladvocate.com/child-custody/This information shows a way that Karren's story could be consistent with the information in the court docket. First, although Karren talkes about "full custody," that is not an accurate legal term for child custody in Utah. At one point, he says the actual term is "primary custody." The technically correct term in Utah seems to be "sole custody," but it also seems that "primary custody" and "sole custody" are used interchangeably.
Utah splits custody into two parts: physical and legal. Physical is where the child lives. Legal is who makes decisions. Joint legal custody is generally presumed. A parent has "sole" custody if the chid resides with that parent more than 253 days per year. In that case, the other parent is entitled to what is called "parent time."
So, it is possible that the original decree awarded Karren sole physical custody, but also awarded joint legal custody. If that is true, Kerran's 2012 motion for "full custody" could have been a motion to change the joint legal custody into sole legal custody. If that is true, his story is completely consistent with the court docket. In other words, with the new information, I don't think the court docket undermines Karren's story in any way.
The docket makes it clear that there was no trial over custody. Karren and his ex agreed to a custody arrangement. As is typical, the agreed order was signed off on by a Court Commissioner. The docket indicates the Commissioner asked each of them on the record whether they agreed, which they did. Generally, when the parties agree (and there is no evidence of abuse, etc.), the Commissioner will sign. So there is nothing inconsistent about Karren being in contempt earlier in the process and his eventual award of sole physical custody.
The original decree is publicly available. Since I'm cheap, I'll likely wait to see if he produces a copy.
This doesn't change my opinion on not trusting what Karren says without corroboration.
