Child Custody orders are signed by a judge and set the rules for where a child stays (custody), when the parent the child is not staying with sees the child (visitation), and child support. The Family Law Self-Help Center provides explanations, instructions, and forms for beginning or answering a custody case and also for modifying an existing child custody order.
The Alaska Court System provides free and low-cost mediation programs for child custody/visitation cases, child-in-need-of-aid (CINA) cases, & adult guardianship/conservatorship cases. Information about these programs in particular, and mediation in other matters is available here.
The Alaska Court System's Family Law Self-Help Center has excellent explanations, and all of the forms necessary to end your marriage.
