CasewellThe law in plain words
Under Idaho Code 32-717B, "there shall be a presumption that joint custody is in the best interests" of the child. The exception is a parent found to be a habitual perpetrator of domestic violence.
Wondering who usually ends up with custody? Our page on the chances of getting full custody in Idaho explains what the figures can and cannot show.
Custody terms in Idaho
Idaho uses these terms.
- Joint legal custody: parents share major decisions about the child's health, education and welfare.
- Joint physical custody: each parent has the child for "significant periods" of time.
- Joint custody: time is shared so the child has frequent, continuing contact with both parents.
- Sole custody: one parent has custody, and the other usually has parenting time.
People often say "full custody," but Idaho orders usually describe legal custody, physical custody and parenting time. A parent without primary physical custody can still get the child's medical, dental and school records.
Is Idaho a 50/50 state?
Not exactly. Idaho presumes joint custody, but joint custody does not mean equal time.
- The statute: joint physical custody "does not necessarily mean" each parent's time is the same length.
- The judge decides the time. The Supreme Court has upheld uneven splits under joint custody.
- Refusing joint custody: a judge who refuses it must give reasons in the decision.
In Raber v. Raber (2025), the Supreme Court threw out an equal schedule that had a 4-year-old flying between Texas and Idaho every two weeks. The trial court had not weighed the travel, schooling and stability.
In 2026, a bill to presume equal parenting time died in committee.
The best-interest factors
Under Idaho Code 32-717, the court must consider all relevant factors. The law lists these as examples, not a checklist that decides the case:
- each parent's wishes
- the child's wishes
- the child's relationships with parents and siblings
- the child's adjustment to home, school and community
- the character and circumstances of everyone involved
- the need for continuity and stability in the child's life
- domestic violence, whether or not the child saw it
The list is not complete, and judges can weigh other factors. A parent's disability alone cannot count against them. A grandparent the child lives with can be treated like a parent.
Your child's preference
Idaho sets no age at which a child chooses. A child's views may be considered, but the judge makes the decision. A child becomes an adult at 18.
- Private interview: since January 2025, a judge may talk with the child privately. The interview is recorded and may be sealed.
- No testimony by default: outside emergencies, a child does not testify or come to court without a court order.
- Asking for testimony: a parent must file and serve a written motion at least 28 days before the hearing, unless there is good cause.
- Child advocate: the court can appoint a lawyer for the child, or a guardian ad litem.
A guardian ad litem must ask any child who can express wishes what those wishes are.
Mothers' and fathers' rights
Married parents start equal. Under Idaho Code 32-1007, the father and mother of a child of married parents are "equally entitled" to custody. That includes parents who married after the birth.
An unmarried father must first establish legal paternity, by a filed acknowledgment or a court order. After that, the same test applies to both parents.
No Idaho statute we found gives the mother of a child of unmarried parents custody by default.
A father's chances depend on the same evidence as anyone's: his role, his home and the child's needs.
If you were never married
No Idaho law we found automatically gives either unmarried parent custody, or sets a schedule, before a court order. Courts apply the same best-interest factors as in a divorce.
Even without an order, avoid keeping the child from the other parent. Once there is an order, follow it. If safety is your worry, get legal advice quickly.
- Acknowledgment of paternity: once signed, notarized and filed with Vital Statistics, it is a legal finding of paternity.
- Changing your mind: a signer can file a notarized cancellation with Vital Statistics within 60 days of filing. If a court or agency case about the child starts sooner, and the signer is a party, the deadline is earlier.
- After that: it can be challenged only in court, for fraud, threats or pressure, or a serious mistake about the facts.
- Deadline: a paternity case can be filed any time before the child turns 18.
To get custody or parenting time, file a Petition for Paternity, Custody, Visitation and Support. Once paternity is ordered, the child has the same legal standing as any child.
Domestic violence
Domestic violence is a factor, even if the child did not see it. Idaho defines it as physical injury, sexual abuse, forced imprisonment, or a threat of these.
- Habitual abuse: if a parent is a "habitual perpetrator," the law presumes joint custody is not in the child's best interests.
- What habitual means: more than one incident, the Supreme Court said in Michalk v. Michalk (2009).
- Overcoming it: the presumption is a starting assumption that parent can try to disprove.
- Child abuse claims in a divorce: if a parent is accused of child abuse, the court must order a state child welfare investigation. No final custody order is entered until the report arrives.
Idaho's definition does not include coercive control. Free domestic violence legal advice is available from Idaho Legal Aid at (877) 500-2980.
Protection orders
A protection order is free: there is no filing, service or hearing fee.
- Who can file: a victim, or someone on behalf of a family or household member who is a victim. A parent or guardian can file for a child.
- Where: the county where you live, where the other parent lives, or where you are staying.
- Emergency order: the court decides on the day you file, or the next court day. It lasts up to 14 days and can be reissued.
- Full hearing: within 14 days. It can be delayed so a party without a lawyer can get one.
- Custody: if you ask and show immediate danger, a protection order can include temporary custody. It must fit any existing custody order, unless the child's interests justify a change.
- How long: a full order lasts up to a year. It can be renewed or made permanent.
Leaving home to escape abuse does not affect your right to file.
Emergency and temporary orders
If your child faces immediate, serious harm, ask the court about an emergency temporary order. The court may set a prompt hearing and temporarily change custody or parenting time.
- Sworn facts: the judge needs sworn facts that clearly show the danger.
- Temporary: an emergency order is short-lived, and the other parent can ask the court to end or change it.
- Temporary orders: while a case is open, file a sworn motion with a proposed parenting schedule.
- Abuse: a protection order can include temporary custody, as above.
Idaho courts can also act in an emergency to protect a child who is in the state.
Moving with your child
Idaho has no relocation statute. The rules come from court decisions.
- The burden: the parent who wants to move must show the move is in the child's best interests.
- No presumption against moving: joint custody is not a presumption against a move. Judges still weigh the value of frequent, continuing contact with both parents.
- What judges weigh: each parent's reasons, the child's bonds, the benefits of the move and whether visits can keep the relationship strong.
- Distance: travel distance must be considered, the Supreme Court said in 2025.
The Supreme Court confirmed these rules in Bickerstaff v. Bickerstaff (2026). These cases show how judges decide, but they do not guarantee the result in your case.
Check your order and any restraining order served with the summons. Do not move against an order or without consent. The consequences depend on the facts and the order.

Changing custody
To change custody, the parent asking must first show a material and substantial change in circumstances since the last order. The court then decides on the child's best interests.
- The petition must describe the changes in detail. It is served on the other parent, not their old lawyer, with a summons.
- Harassing filings: if a request is vexatious and harassing, the filer must pay the other parent's fees and costs.
- Military service: a call-up cannot be used to reduce a service member's custody.
If parenting time is being denied, a faster process applies. The rules presume the motion will be finally decided within 42 days of filing. Remedies include make-up time.
Parenting plans, mediation and classes
- No statewide schedule: Idaho has no default parenting time schedule we could find. The court's parenting plan form is fill in the blank.
- Mediation: the court may order it in any custody dispute. Once the court orders mediation, parents generally have 28 days to choose a mediator. If they do not, the court picks one.
- Cost: each parent usually pays half of the mediator's fees.
- Screening: courts may first assess whether mediation suits the family, including any domestic violence.
- Parenting class: the court may order one. Clerks often issue an order to attend a class, such as Focus on the Children.
The mediator decides nothing. Any agreement is the parents' own and goes to the judge for approval.
How to file for custody in Idaho
Idaho must usually be the child's home state, meaning the child lived there for the six months before filing.
- Choose the case type. Married parents ask for custody in a divorce. Unmarried parents file a petition for paternity and custody.
- Get the forms from the Idaho Court Assistance Office. Include the parenting plan and the income affidavit.
- File in the magistrate division of the district court. Ask the clerk or the Court Assistance Office which county is right.
- Serve the other parent, who has 21 days to respond.
- Attend any class or mediation the court orders.
Idaho Guide and File offers online interviews that fill in the forms. Idaho Legal Aid takes custody cases mainly where there is domestic violence.
