Idaho Child Custody: A Parent's Guide

In short: Idaho presumes joint custody serves a child's best interest, rebuttable by a preponderance of the evidence, and that presumption flips against joint custody where a parent is a habitual domestic violence perpetrator. Relocating requires 60 days' written notice, and the objecting parent has 30 days to contest it before a court hearing decides the outcome.

This is an educational overview written for parents, not lawyers. It isn't legal advice. For anything beyond general understanding, talk to a licensed Idaho family law attorney.

What Idaho generally provides

Idaho Code § 32-717B establishes a rebuttable presumption that joint custody is in a child's best interest, absent a preponderance of the evidence to the contrary. That presumption reverses where a parent is found to be a habitual perpetrator of domestic violence, in which case joint custody is presumed not to serve the child's best interest.

Important terminology

• Joint custody: an order sharing physical custody in a way that ensures frequent and continuing contact with both parents; can include joint physical custody, joint legal custody, or both.
• Habitual perpetrator presumption: the statutory flip that presumes joint custody is not appropriate where a parent has a pattern of domestic violence.
• Best interest of the child: Idaho's controlling standard, assessed through the factors in § 32-717.

How custody works in Idaho

A rebuttable presumption favoring joint custody

Unless a preponderance of the evidence shows otherwise, Idaho courts start from the assumption that joint custody serves the child's best interest. Either parent can rebut that presumption with sufficient evidence tied to the § 32-717 factors.

The underlying best-interest factors

Courts weigh the wishes of the child's parents, the wishes of the child, the interaction and relationship between the child and each parent and any siblings, the child's adjustment to home, school, and community, the character and circumstances of everyone involved, the need to promote continuity and stability, and any domestic violence, whether or not it occurred in the child's presence.

Parenting schedules

Given Idaho's joint-custody starting point, families commonly build the actual schedule around patterns like 2-2-3 or week on, week off. See what is a parenting plan for what a strong plan generally covers, how to choose a custody schedule for a general framework, and the custody schedule generator to build the actual calendar.

Moving with your child (relocation)

A parent planning to relocate with the child must give the other parent at least 60 days' written notice, including the destination, the reasons for the move, and a proposed revised visitation schedule. The other parent then has 30 days after receiving notice to object; if they do, the court holds a hearing to decide whether the move serves the child's best interest. The relocating parent bears the burden of showing the move benefits the child when it's contested. Not every move triggers these rules, the focus is on relocations, whether across state lines or a substantial in-state distance, that would change the ability to follow the existing custody or visitation plan. See moving to another state with shared custody for how relocation standards tend to work more broadly across states.

Common questions

How is child support calculated? Idaho uses the income shares model: both parents' guidelines income (gross income minus specific allowed deductions) is combined, referenced against the statutory schedule, and split proportionally, with health insurance, work-related childcare, and extraordinary medical expenses over $250 per child per year added on top. The combined income cap is $440,000 per year, with guidelines most recently amended effective July 1, 2025.

Can a custody order be changed later? Yes, generally on a showing of a substantial and material change in circumstances and that a modification serves the child's best interest.

What if my co-parent won't follow the custody order? You can file a motion for contempt or to enforce the order with the court. Courts can order makeup time and, in serious or repeated cases, hold a parent in contempt.

Practical considerations

Because Idaho's joint-custody presumption is rebuttable in both directions, depending on whether domestic violence is a factor, documenting the relevant facts early matters, whether you're seeking to preserve the presumption or rebut it, and worth discussing directly with an Idaho family law attorney. Whatever the order specifies, the operational part that follows it, keeping both households aligned on the same schedule, logging change requests instead of relying on memory, and keeping a record if an enforcement issue arises, is a separate, ongoing piece worth planning for.
