Utah Code 81-9-204: Best Interests of the Child Factors
Utah Code § 81-9-204: Best Interests of the Child Factors
Every custody and parent-time decision in Utah District Court runs through one test: the best interests of the child under Utah Code § 81-9-204. There's no formula, no point system, and no automatic winner. The judge weighs a broad set of statutory factors and makes a judgment call based on the specific circumstances of your family.
Understanding these factors — and knowing what the court is explicitly prohibited from considering — gives you a concrete framework for preparing your case.
The Statutory Factors
The court must evaluate these categories when making custody and parent-time determinations:
Parental Conduct and Capacity
- Moral and financial conduct of each parent — not just income, but whether each parent manages resources responsibly and models appropriate behavior
- Physical, mental, and emotional health of each parent — the court looks at whether a parent's health affects their ability to provide stable daily care
- Willingness to facilitate the other parent's relationship — this is one of the most heavily weighted factors. A parent who actively supports the child's bond with the other parent gets significant credit. A parent who interferes with or undermines that relationship faces serious consequences.
Parent-Child Relationships
- History and quality of each parent's existing relationship with the child — who the child turns to for comfort, who handles daily routines, who shows up for school events
- Relationships with siblings, extended family, and other significant people — the court weighs whether separating siblings or cutting off close relationships with grandparents would harm the child
- Developmental and emotional needs specific to this child — a toddler's attachment needs differ from a teenager's independence needs
Stability and Environment
- Benefit of keeping siblings together in one household
- Physical safety and facilities of each parent's home
- Historical caregiving roles — who was the primary caregiver before separation? The parent who made breakfast, managed homework, drove to doctor's appointments, and coordinated the child's daily life has a meaningful advantage, not because of a formal presumption, but because the court values continuity
Safety Concerns
- Any history of domestic violence, neglect, or physical, sexual, or emotional abuse
- Evidence of psychological maltreatment or parental alienation — deliberately turning a child against the other parent
- Whether a parent has intentionally exposed the child to pornography or inappropriate sexual materials
The Child's Preferences
The court may consider what the child wants, but it is never the single controlling factor. For children age 14 and older, the statute requires the judge to give "added weight" to their expressed preferences. The child's views are typically obtained through a judge-led in-camera interview — a private conversation in chambers, away from both parents — to shield the child from loyalty conflicts.
What the Court Cannot Consider
Three categories are explicitly prohibited under § 81-9-204:
Gender. No custody preference based on the parent's or child's gender. A father and mother are evaluated identically.
Lawful medical cannabis use. A parent cannot be disadvantaged for holding a valid medical cannabis card, using medical cannabis as prescribed, or working at a licensed cannabis facility.
Beliefs about gender identity and sexuality. The court cannot penalize a parent for agreeing or disagreeing with their child's beliefs, expressions, or medical pathways related to gender identity, gender expression, or sexual orientation.
These prohibitions are absolute. If opposing counsel raises any of these as evidence of parental unfitness, object immediately.
How to Use This in Your Case
The best-interest factors aren't a checklist you "win" by scoring more points. They're the framework the judge uses to evaluate your parenting arrangement. The most effective approach is to document your role in each category with specific evidence:
- Keep records of who handles daily caregiving tasks
- Document your support of the child's relationship with the other parent (texts encouraging visits, coordinating schedule flexibility)
- Maintain a stable home environment and demonstrate consistent involvement in school, healthcare, and extracurriculars
