The current standard that Utah courts are required to follow when it comes to the fate of children in a divorce or separation is what is in the best interests of the children. The basic assumption is that the being with a parent fulfills that standard. However, there are instances where the children would be better off with their grandparents, and the law does allow for these relatives to petition the court for child custody or visitation.
It can be a challenge to overcome the assumption that the best interests of the children would be served by a parent receiving custody. However, Utah courts might consider granting a grandparent custody of the children under certain circumstances. If it can be proved through appropriate evidence that one or both parents are somehow unfit or not competent to care for the children, a grandparent might be awarded custody or visitation.
