How Is Custody Decided in Wyoming?

You know that custody will be part of your divorce, but you are not sure what the process actually looks like — who decides, based on what criteria, and how much control you have over the outcome. Wyoming provides three paths to a custody determination, each with different levels of parental control and judicial involvement. Understanding which path your case is on, and what the judge looks for if the decision reaches the bench, helps you prepare effectively rather than reacting to each step as it comes.

Path 1: Parental Agreement

The simplest and least expensive path. If both parents agree on legal custody, physical custody, the parenting time schedule, and child support, they submit a joint parenting plan with their divorce paperwork. The judge reviews it for completeness and to confirm it serves the child's best interests, and in most cases, approves it.

This is not a rubber stamp — the judge can reject a proposed plan that appears to compromise the child's welfare, even if both parents agree to it. But in practice, courts give substantial deference to agreements reached between two willing parents who have thought through the details.

If your case is headed toward agreement, the effort you put into drafting a detailed, specific parenting plan pays off here. A thorough plan with clear schedules, exchange protocols, and dispute resolution procedures is far more likely to receive judicial approval than a vague agreement to "share custody equally."

Path 2: Mediation

When parents agree on some issues but are stuck on others, the court can order mediation. Under Wyoming Rules of Civil Procedure Rule 16, district court judges frequently use their discretion to require mediation before allowing a contested custody case to proceed to trial.

A mediator is a neutral third party who helps the parents negotiate. The mediator has no decision-making authority — they facilitate the conversation and help both sides explore options they may not have considered. If mediation produces a full agreement, that agreement is submitted to the court as a stipulated parenting plan. If mediation resolves some issues but not all, the remaining disputes go to the judge.

Mediation is confidential under Wyo. Stat. § 1-43-101. Nothing either parent says during mediation can be used as evidence in court if the case goes to trial. This confidentiality is designed to encourage honest, open negotiation without fear that a concession made during mediation will be held against you later.

Private mediators in Wyoming typically charge $150 to $300 per hour, split between the parents. Some courts have access to lower-cost mediation programs for families who qualify. The investment is almost always worth it — a day of mediation costs a fraction of what a contested trial costs, and parents who reach their own agreement tend to comply with the plan more consistently than parents who have terms imposed by a judge.

Path 3: Judicial Decision at Trial

When the parents cannot agree — even with mediation — the judge decides. This is a bench trial (no jury in Wyoming custody cases). Both parents present evidence, call witnesses, and argue why their proposed custody arrangement serves the child's best interests. The judge evaluates everything against the statutory best-interest factors and issues a ruling.

The Statutory Best-Interest Factors

Under Wyo. Stat. § 20-2-201(a), the court must consider a non-exhaustive list of factors. No single factor is decisive — the judge weighs them collectively:

The quality of the relationship with each parent. Who has been the hands-on caregiver? Who handles school pickups, bedtime routines, doctor's appointments, homework? The court looks at actual daily involvement, not which parent earns more or which parent claims to love the child more.

Each parent's ability to provide care. Can each parent practically handle the child during their proposed custodial time? This includes arranging childcare when needed (for work hours, for example). A parent who works 80 hours a week and relies entirely on grandparents for care may be evaluated differently than a parent with a more flexible schedule.

Competency and fitness. Physical and mental ability to care for the child. Untreated substance abuse, active domestic violence, or severe mental health issues that impair parenting function weigh against a parent.

Willingness to accept parenting responsibility. Is each parent genuinely willing to be the custodial parent — accepting the daily work, not just the title? A parent who wants custody primarily to avoid paying child support, rather than to be a daily presence in the child's life, will not perform well under this factor.

Supporting the child's relationship with the other parent. This factor carries significant weight. Courts pay close attention to which parent encourages (or undermines) the child's relationship with the other parent. Interference with visitation, disparaging the other parent in front of the child, or attempting to alienate the child from the other parent can shift custody.

Communication and cooperation. How do the parents interact? Can they make joint decisions about the child? The Wyoming Supreme Court's decision in Gurney v. Gurney emphasizes that shared physical custody requires strong parental communication — if parents cannot cooperate, the court will typically award sole physical custody to one parent.

Geographic distance. How far apart do the parents live? A 50/50 schedule is impractical when parents live 200 miles apart.

Any other relevant factor. The list is non-exhaustive. Judges can consider anything they deem pertinent to the child's welfare.

Custody Evaluations

In complex contested cases, the court may order a custody evaluation under Rule 35 of the Wyoming Rules of Civil Procedure. A licensed psychologist or mental health professional conducts a comprehensive assessment of both parents and the child, including formal psychological testing, home observations, and clinical interviews.

Custody evaluations are expensive — typically $2,500 to $5,000 — and add months to the litigation timeline. But in cases involving fitness disputes, domestic violence allegations, or severe parental conflict, the evaluation gives the judge a clinical perspective that goes beyond the testimony each parent presents in their own favor.

The evaluator submits a report to the court with their recommendation. Like a guardian ad litem's report, the custody evaluation is one piece of evidence the judge considers — not a binding determination. Either parent can challenge the evaluator's findings at trial.

What You Can Do to Prepare

Regardless of which path your case takes, the preparation is the same. Organize your evidence around the statutory best-interest factors: document your daily parenting involvement, maintain stable housing and routines, demonstrate willingness to cooperate with the other parent, and keep a factual log of any issues that affect the child's welfare.

The Wyoming Child Custody & Parenting Plan Guide includes a best-interests self-assessment worksheet that maps your situation against each statutory factor, helping you identify your strongest areas and address any gaps before you present your case — whether that is to a mediator, a custody evaluator, or a judge.
