Why Would an Idaho Judge Not Grant 50/50 Custody?

An Idaho judge may not grant 50/50 custody when dividing the child’s time equally would not be in the child’s best interests. The court may find that the parents should share custody but still order an unequal parenting schedule because of distance, school demands, caregiving history, safety concerns, a child’s special needs, or practical problems with the proposed plan.

The important point is that Idaho’s preference for joint custody is not a requirement that every child spend exactly half of the year with each parent. Contact a Boise child custody lawyer from Brown Family Law today.

Joint Custody Does Not Automatically Mean Equal Time in Idaho

Idaho law creates a rebuttable presumption that joint custody is in a child’s best interests in most cases. That gives courts a starting point favoring the continued involvement of both parents.

It does not create an automatic right to 50 percent of the parenting time.

Idaho Code § 32-717B specifically states that joint physical custody does not necessarily mean the child’s time with each parent must be exactly equal. It also does not require the child to alternate between homes in a particular pattern. The judge determines the actual amount of time each parent receives.

This means an Idaho court may order joint physical custody even when one parent has substantially more overnights.

For example, a child might live primarily with one parent during the school week while spending alternating weekends, holidays, school breaks, and extended summer periods with the other parent. The arrangement could still provide both parents with significant parenting time and frequent contact.

Idaho Judges Ask Whether the Schedule Works for the Child

Parents sometimes approach custody as though the court is dividing something owned by both adults. If each parent has equal rights, they reason, each should receive an equal number of nights.

That is not how the court is required to approach the issue.

The judge is creating a living arrangement for a child. The court must consider what the child’s weekdays, transportation, school attendance, medical care, activities, and transitions will actually look like.

Under Idaho Code § 32-717, the court considers all relevant circumstances, which may include:

• The parents’ wishes
• The child’s wishes
• The child’s relationships with the parents and siblings
• The child’s adjustment to home, school, and community
• The character and circumstances of the people involved
• The need for continuity and stability
• Domestic violence, whether or not it occurred in the child’s presence

These are not boxes that the judge simply counts. One serious issue may matter more than several less significant facts. The weight given to each fact depends on the child and the evidence presented.

In a 2026 decision, the Idaho Supreme Court reaffirmed that custody courts consider the statutory factors along with other circumstances relevant to the particular case. The analysis is not a scoreboard in which the parent who “wins” the greatest number of factors automatically wins the custody dispute.

The Proposed Schedule May Be Too Difficult to Follow

One of the most common problems with a 50/50 request is that the proposed schedule is not practical.

Equal parenting time may require frequent exchanges, particularly under arrangements such as a 2-2-3 or 2-2-5-5 schedule. Those transitions can become difficult if the parents live in different communities or have conflicting work hours.

A judge may ask:

• How far apart are the two homes?
• How long will the child spend in the car?
• Which parent will provide transportation?
• Can both parents get the child to school on time?
• Does the child attend school near either home?
• What happens when school is canceled or the child is sick?
• How will homework, uniforms, medication, and school materials move between homes?
• Can the child continue participating in current activities?
• Who will provide childcare when a parent is working?
• Will the parents realistically complete all required exchanges?

A request for equal time is more persuasive when it answers these questions. Simply stating that 50/50 custody is “fair” does not show the judge that the arrangement will work.

Distance Between the Homes Can Defeat Equal Time

Parents do not have to live in the same neighborhood to share custody. However, distance can make an equal schedule difficult, especially during the school year.

A 30-minute trip may appear manageable until it must be made twice a day through winter weather, traffic, or conflicting work schedules. Greater distances can make weekday exchanges impractical altogether.

The concern is not whether one parent should be punished for moving. The court looks at how the distance affects the child.

A judge may prefer a schedule with fewer exchanges and longer blocks of time. One parent might have more school-year overnights, while the other receives additional summer, holiday, and school-break time.

The Child May Need One Consistent School-Week Home

Some children can move between two homes easily. Others struggle when books, assignments, clothing, equipment, medication, or comfort items must constantly travel with them.

A judge may order an unequal schedule if equal time is causing or is likely to cause:

• School absences or tardiness
• Missed assignments
• Inconsistent bedtime routines
• Forgotten medication
• Missed practices or appointments
• Anxiety around exchanges
• Behavioral problems after transitions
• Difficulty maintaining friendships
• Confusion about transportation
• Loss of needed structure

This does not necessarily mean that one home is better than the other. The court may simply determine that the child needs a more consistent school-week routine.

The child’s age can also matter. An infant, a teenager, and a child with developmental or sensory difficulties may respond very differently to the same schedule.

Past Parenting Experience May Influence the Initial Plan

The court may examine what each parent actually did before the custody case began.

Relevant questions may include:

• Who prepared meals?
• Who handled bedtime?
• Who took the child to school?
• Who arranged medical appointments?
• Who communicated with teachers?
• Who supervised homework?
• Who managed therapy or medication?
• Who stayed home when the child was sick?
• Has each parent cared for the child overnight without assistance?
• Has either parent been absent for a significant period?

A parent does not have to prove that every caregiving responsibility was divided equally during the relationship. Many families divide responsibilities based on employment and other practical needs.

However, a parent requesting immediate 50/50 custody should be prepared to show that the parent can handle the child’s daily care. If that experience is limited, the judge may order a gradual increase in parenting time instead of beginning with equal overnights.

A Parent’s Work Schedule May Not Support the Request

Having a demanding job does not prevent someone from being an excellent parent. Using childcare also does not make a parent unfit.

The issue is whether the parent will be available for the parenting time being requested.

A judge may question an equal schedule when a parent:

• Works overnight during most scheduled custody time
• Travels frequently with little notice
• Cannot transport the child to school
• Has unpredictable shifts and no dependable childcare
• Regularly cancels parenting time
• Plans to leave the child with third parties for most of the requested time
• Has not explained how emergencies or school closures will be handled

A strong plan identifies the parent’s actual work hours, available childcare, transportation arrangements, and backup options.

Safety Concerns Can Outweigh the Preference for Shared Custody

Domestic violence, child abuse, neglect, dangerous substance use, and other serious risks can result in limited or supervised parenting time.

Idaho law requires domestic violence to be considered even if the violence did not occur in the child’s presence. The question is not limited to whether the child was physically injured. Violence in the home can affect a child’s emotional security and can make safe co-parenting difficult.

There is also an important statutory exception to Idaho’s joint-custody presumption. Under Idaho Code § 32-717B, when a court finds that a parent is a habitual perpetrator of domestic violence, joint custody is presumed not to be in the child’s best interests.

Evidence relevant to a safety concern may include:

• Protection orders
• Police reports
• Criminal records
• Medical documentation
• Child welfare records
• Photographs
• Threatening communications
• Witness testimony
• Drug or alcohol testing
• Treatment records
• Evidence of impaired driving
• Proof that the child was left without appropriate supervision

The court may impose supervision, require sober exchanges, establish conditions for increased parenting time, or use another arrangement intended to protect the child.

A parent should not exaggerate ordinary disagreements into claims of abuse. At the same time, credible safety concerns should not be minimized merely because the other parent is requesting equal custody.

Substance Misuse Must Be Connected to Parenting

Past alcohol or drug use does not automatically decide custody. A diagnosis or history by itself may tell the judge very little about the parent’s current ability to care for the child.

The more important questions are whether the parent:

• Becomes impaired during parenting time
• Drives with the child after drinking or using drugs
• Leaves substances accessible to the child
• Fails to supervise the child
• Misses exchanges because of substance use
• Brings unsafe individuals into the home
• Refuses court-ordered testing
• Has completed or is participating in treatment
• Has demonstrated a sustained period of stability

A court may distinguish between a parent who recognizes a problem and responsibly participates in recovery and a parent whose active substance misuse continues to endanger the child.

Constant Conflict Can Make Equal Time Harmful

Parents do not need to be friends to share physical custody. They can disagree, communicate in writing, and follow a detailed parenting plan.

The problem arises when the conflict repeatedly reaches the child.

Examples include:

• Fighting during exchanges
• Asking the child to deliver hostile messages
• Questioning the child about the other household
• Refusing to share school or medical information
• Calling the police over routine schedule disagreements
• Encouraging the child to take sides
• Making important decisions only to upset the other parent
• Repeatedly refusing to return the child as ordered
• Scheduling activities to interfere with the other parent’s time
• Using the child to obtain information about a former spouse’s personal life

An Idaho judge may determine that fewer exchanges or a more detailed schedule will better protect the child. In some cases, the court may award joint legal custody but structure physical custody unequally. In others, the evidence may support more substantial restrictions.

A Child’s Medical or Developmental Needs May Require a Different Plan

A standard 50/50 schedule is not automatically appropriate for a child who has complex needs.

The court may need to consider:

• Medical treatments
• Medication schedules
• Physical or occupational therapy
• Mental health treatment
• Educational accommodations
• Developmental disabilities
• Mobility limitations
• Sensory sensitivities
• Sleep difficulties
• Nursing or feeding needs
• The child’s ability to manage frequent transitions

Both parents may be capable of caring for the child, but one home might be closer to treatment, better equipped, or more compatible with the child’s school and therapy schedule.

The judge may also consider whether each parent understands the child’s condition and follows professional recommendations.

The Child’s Wishes May Matter, but the Child Does Not Decide

Idaho law allows a judge to consider a child’s wishes. It does not give the child unilateral authority to choose the custody schedule.

The importance of the child’s preference will depend on the child’s maturity, reasoning, consistency, and circumstances. A thoughtful teenager concerned about school, transportation, employment, or emotional stability may receive more consideration than a young child who prefers the household with fewer rules.

The court may also look for signs of coaching or pressure. Parents should not ask a child to choose between them or promise rewards for supporting a particular custody arrangement.

Conduct That Interferes With the Other Parent May Hurt a 50/50 Request

Idaho’s joint-custody policy is intended to provide children with frequent and continuing contact with both parents.

A parent may undermine a request for equal custody by:

• Denying parenting time without a legitimate reason
• Hiding information about the child
• Making unilateral school or medical decisions
• Preventing reasonable telephone contact
• Refusing to follow exchange provisions
• Making unsupported accusations to damage the other parent
• Trying to replace the other parent with a new spouse or partner
• Treating parenting time as leverage in financial negotiations

Protecting a child from a genuine danger is different from interfering with the other parent. When restrictions are necessary for safety, the parent should be prepared to explain the concern and present reliable supporting evidence.

What Usually Does Not Prevent 50/50 Custody by Itself?

Certain facts may sound damaging but do not necessarily establish that equal custody would be inappropriate.

Standing alone, the following may not be enough:

• One parent earns less money.
• One parent rents rather than owns a home.
• A parent works full time.
• The parents have different parenting styles.
• A parent has a mental health diagnosis that is being appropriately managed.
• A parent begins a new relationship.
• One parent was responsible for more childcare during the marriage.
• The child shares a bedroom with a sibling.
• The parents dislike each other.
• One parent filed for divorce first.

The court needs to understand how the situation affects the child. A lower income is different from an inability to provide basic care. A mental health diagnosis is different from unmanaged symptoms that create a safety risk. A new relationship is different from exposing the child to a dangerous person.

Specific effects matter more than labels.

What Evidence Helps a Judge Evaluate the Schedule?

A parent seeking or opposing 50/50 custody should focus on evidence showing how the proposed arrangement would operate.

Useful evidence may include:

• A calendar documenting actual parenting time
• School attendance and tardiness records
• Work schedules
• Childcare information
• Medical and therapy records
• Communications concerning the child
• Exchange logs
• Transportation estimates
• Records of missed parenting time
• Evidence of involvement in school and healthcare
• Police reports or protection orders
• Substance testing results
• A detailed proposed parenting plan
• Testimony from witnesses with firsthand knowledge

Broad accusations are rarely as useful as specific facts. “The schedule is chaotic” is a conclusion. Records showing repeated late school arrivals after exchanges provide the court with something concrete to evaluate.

How Can a Parent Make a 50/50 Proposal More Credible?

A workable request should address more than the number of overnights.

The proposed parenting plan should explain:

• The regular weekly schedule
• Holiday and vacation time
• Exchange locations and transportation
• School-day responsibilities
• Childcare
• Medical and educational decisions
• Communication between the parents
• How belongings and medication will move between homes
• Procedures for schedule changes
• What happens when the child is sick
• How the plan accommodates activities
• How disputes will be handled

A parent should also be realistic. A carefully designed shared schedule is more persuasive than insisting on exactly half the nights when the logistics do not support it.

A Different Schedule Does Not Mean a Parent Lost Custody

A judge’s refusal to order 50/50 time does not necessarily mean the judge believes one parent is unimportant or unfit.

The court may award:

• Joint legal custody with unequal physical custody
• Joint physical custody with one primary school-week residence
• Alternating weekends and midweek parenting time
• Extended summer and holiday periods
• A gradual step-up schedule
• Longer parenting blocks with fewer exchanges
• Supervised parenting time followed by expanded time when conditions are met

The actual schedule and decision-making authority matter more than the label alone.

Speak With an Idaho Child Custody Attorney

An Idaho judge may decline to grant 50/50 custody because equal parenting time is not automatically required under Idaho law. Although joint custody is generally presumed to serve a child’s best interests, Idaho law expressly allows joint physical custody to involve unequal amounts of time.

The outcome usually depends on whether the proposed arrangement supports the child’s safety, stability, schooling, relationships, and daily needs.

Brown Family Law can help you evaluate an equal-custody proposal, identify weaknesses in an unworkable plan, and present evidence showing what arrangement would best serve your child.
