Types of Custody in Idaho
Idaho recognizes several types of custody arrangements:
| Type | Description |
|---|---|
| Legal Custody | The right to make major decisions about the child’s education, healthcare, and religious upbringing. |
| Physical Custody | Where the child primarily lives on a day-to-day basis. |
| Joint Custody | Both parents share legal custody, physical custody, or both. |
| Sole Custody | One parent has exclusive legal or physical custody. |
Joint custody presumption: YES. Under Idaho Code § 32-717B, absent a preponderance of the evidence to the contrary, there is a presumption that joint custody is in the best interests of a minor child or children. This presumption applies to both legal and physical custody. However, the presumption reverses if one parent is found to be a habitual perpetrator of domestic violence — in that case, the presumption is that joint custody is NOT in the child’s best interests.
Idaho Best Interest of the Child Standard
The best interests of the child standard is the primary framework Idaho courts use for all custody decisions. This standard considers what arrangement will best serve the child’s physical, emotional, and developmental needs.
Idaho courts evaluate these best interest factors when making custody decisions:
- Idaho Code § 32-717(1) requires the court to consider all relevant factors
- which may include: (a) The wishes of the child’s parent or parents as to his or her custody; (b) The wishes of the child as to his or her custodian; (c) The interaction and interrelationship of the child with his or her parent or parents
- and his or her siblings; (d) The child’s adjustment to his or her home
- school
- and community; (e) The character and circumstances of all individuals involved; (f) The need to promote continuity and stability in the life of the child; (g) Domestic violence as defined in section 39-6303
- Idaho Code
- whether or not in the presence of the child. Additionally
- § 32-717(3) provides that if a parent has a disability
- the parent has the right to provide evidence regarding adaptive equipment or supportive services that enable them to carry out parenting responsibilities. Section 32-717(4) also allows a grandparent with whom the child is actually residing in a stable relationship to have the same standing as a parent.
Child’s preference: In Idaho, a child’s custody preference may be considered when the child reaches No specific statutory age. Idaho Code § 32-717(1)(b) requires the court to consider “the wishes of the child as to his or her custodian” as a best-interest factor but sets no minimum age. In practice, courts give greater weight to the preferences of older, more mature children; children age 12 and older typically receive significant consideration. Under IRFLP Rule 117 (effective 2025), judges may interview children privately in chambers about their preferences.. The weight given to the child’s preference increases with age and maturity. The court considers the child’s reasoning and whether the preference is influenced by a parent.
Idaho Parenting Plans
Idaho requires parents to submit a parenting plan as part of custody proceedings. The Idaho parenting plan (CAO-FL3) must include: (1) A residential/parenting time schedule with specific days and times showing when children will be with each parent; (2) A holiday schedule covering Martin Luther King Day, Presidents’ Day, Spring Break, Easter, Mother’s Day, Memorial Day, Father’s Day, Fourth of July, Labor Day, Halloween, Thanksgiving Break, December 24, December 25, New Year’s Day, Christmas Break (1st and 2nd parts), and each child’s birthday, with alternating-year provisions and a rule that if holidays result in 3 consecutive weekends with one parent, the other parent gets the following weekend; (3) Decision-making authority allocation for education, healthcare, religious upbringing, and extracurricular activities; (4) Vacation time provisions with advance written or electronic notice requirements; (5) Transportation arrangements for exchanges; (6) Communication schedule for phone, video, and in-person contact with the non-residential parent; (7) Relocation notice requirements; (8) Dispute resolution process before returning to court; (9) Provisions for scheduling changes with required advance notice.
Key elements of an effective parenting plan:
- Regular residential schedule (weekdays, weekends, overnights)
- Holiday and school vacation rotation
- Transportation arrangements and pickup/drop-off logistics
- Decision-making authority (education, healthcare, extracurriculars)
- Communication methods between parents and between parent and child
- Dispute resolution process (mediation before court)
- Right of first refusal when a parent is unavailable
Idaho Custody Relocation Rules
Idaho requires a parent who wants to move more than 50 miles from their current home or outside the state to provide written notice to the other parent, typically sent via certified mail or another method proving delivery. Idaho treats relocation as a significant modification to the existing custody order, and the guiding principle remains the best interests of the child under Idaho Code § 32-717. If the non-relocating parent objects, they must file a formal response within 21 days of receiving notice. Failure to provide proper notice can result in the court ordering the child’s return, modifying custody orders, or finding the relocating parent in contempt.

Notice requirement: The relocating parent must provide 60 days advance written notice before the planned move. days advance written notice to the other parent.
The court evaluates whether the move serves the child’s best interests, considering the reason for the move, the impact on the child’s relationship with the non-moving parent, and whether a modified visitation schedule can preserve that relationship.
Modifying Idaho Custody Orders
To modify an existing custody order in Idaho, the requesting parent must demonstrate a substantial and material change in circumstances that has occurred since the original order was entered, per Idaho Code § 32-717. The modification must also serve the child’s best interests under the same § 32-717 factors. Courts will not modify custody based on temporary changes or minor adjustments. Examples of qualifying changes include: parental relocation making the current schedule impractical, significant changes in a parent’s work schedule or living situation, the child’s changing developmental needs, evidence of abuse/neglect/substance abuse, or repeated failure to follow the existing custody order. The burden of proof is on the parent seeking the change. Idaho Code § 32-720 also addresses servicemember modifications.
Common modification triggers: parent relocation, change in child’s needs, substance abuse, domestic violence, parent’s work schedule change, child reaching an age where preferences are considered, or one parent consistently violating the existing order.
Special Circumstances in Idaho Custody
Domestic violence: Domestic violence is a specifically enumerated best-interest factor under Idaho Code § 32-717(1)(g) — the court must consider domestic violence as defined in § 39-6303, whether or not it occurred in the presence of the child. Under Idaho Code § 32-717B, if a parent is found to be a “habitual perpetrator” of domestic violence (defined as at least 2 incidents), the statutory presumption flips: joint custody is presumed NOT to be in the child’s best interests. This reversed presumption can only be overcome by a preponderance of the evidence. Courts may also grant sole custody to the non-abusive parent and order supervised visitation or supervised exchanges for the abusive parent.
Grandparent visitation: Idaho Code § 32-719 previously allowed grandparents and great-grandparents to petition for reasonable visitation upon a showing that it would be in the child’s best interests. However, in September 2022, the Idaho Supreme Court ruled in Nelson v. Evans (Docket No. 49233) that § 32-719 is facially unconstitutional. The court held that the statute violated parents’ fundamental Fourteenth Amendment right to the custody, care, and control of their children, because it did not limit standing or provide meaningful guidance for applying the best-interests test (i.e., it was not narrowly tailored). As of 2026, grandparents in Idaho effectively have no statutory right to petition for visitation unless the legislature enacts a new, constitutionally compliant statute. Note: § 32-717(4) still allows a grandparent who has been actually residing with and caring for the child in a stable relationship to have standing equivalent to a parent in custody proceedings.
Unmarried parents: In Idaho, the mother of a child born out of wedlock is presumed to have custody. An unmarried father must first establish paternity before he can seek custody or visitation rights. Paternity can be established three ways: (1) Voluntary Acknowledgment of Paternity (AOP) — a legal form signed by both parents, often completed at the hospital at birth; (2) DNA/genetic testing ordered by the court; (3) Court order following a paternity petition filed by either parent, the child, or the Idaho Department of Health and Welfare (Idaho Code Title 32, Chapter 10 — Uniform Parentage Act, § 32-1007). Once paternity is established, the father has the same rights and responsibilities as a married father, including the right to seek custody or visitation under the same best-interest factors of § 32-717. However, establishing paternity does not automatically grant custody — it is a separate determination.
Guardian ad litem: YES. Idaho Code § 32-704(4) (amended by HB 629 in 2024) allows the court to appoint an attorney or guardian ad litem for minor children in divorce and custody actions. In child protective proceedings, Idaho Code § 16-1614 requires appointment of a GAL for children under 12 and appointment of counsel for children 12 and older (with optional additional GAL). In family law custody cases, the appointment is discretionary and typically ordered when there are allegations of abuse, high conflict, or when the court determines the child’s interests need independent representation.
Additional Idaho rules: (1) De facto custodian standing: Idaho Code § 32-1702 et seq. allows a person who has been the primary caregiver and financial supporter of a child for a specified period to petition for custody as a “de facto custodian.” (2) Disability protections: Under § 32-717(3), if a parent’s disability is raised as a custody factor, the parent has the right to present evidence about adaptive equipment or supportive services, and the court must make specific findings about the disability’s effect on the child’s best interests. (3) Parenting coordinator: IRFLP Rule 716 allows the court to appoint a parenting coordinator in high-conflict custody and visitation disputes to help parents implement their parenting plan without returning to court. (4) Virtual visitation: Idaho courts may include provisions for electronic communication (video calls, phone, text) in parenting plans. (5) The “Focus on the Children” class is statewide and unique to Idaho’s family court system as a prerequisite to finalizing custody orders. (6) Idaho Code § 32-717(4) gives grandparents who are actually residing with and caring for a child in a stable relationship the same standing as a parent in custody proceedings — this provision survived even after § 32-719 was struck down.
