Minnesota applies, Minnesota statute § 518.17, and in that statute there are 13 distinct factors that the court must look at and make findings about in deciding the issue. For example, they’ll look at the preference of the child and the parents, they will look at which parent has been the child’s primary custodian, the person that’s provided most of their care. They’ll look at things like how stable the relationship’s been, how long the child has been in a suitable environment, the effect on the child of any domestic abuse that may have taken place, issues like the culture of the child and other factors with relationship to other family members, siblings, the desirability of maintaining continuity in the household, and things like that.
