Wyoming Child Custody Laws (2026): Best Interests Factors and Your Rights

Wyoming decides child custody based on the best interests of the child under W.S. 20-2-201. Wyoming has no statutory presumption for or against any particular custody arrangement; the statute directs courts not to favor or disfavor any form of custody, and an order may combine joint, shared, or sole custody based on the child's best interests.

How does Wyoming decide child custody?

Wyoming family courts apply the best interests of the child standard under W.S. 20-2-201 to every custody determination. The statute provides a non-exhaustive list of factors rather than a rigid numbered formula, giving courts flexibility to focus on the specific circumstances of each child and family. When custody is decided as part of a divorce, the case is filed in the district court of the county where either party resides under W.S. 20-2-104. Separately, for enforcement and modification, W.S. 20-2-203(b) lets a court in any Wyoming county where the child has lived with his parents, a parent, or a person acting as a parent for the six consecutive months immediately before the proceeding began assert jurisdiction over proceedings involving the child. The statute directs courts not to favor or disfavor any particular form of custody, so each case starts from the same best-interests analysis rather than a presumption toward any arrangement. Both parents have the opportunity to present evidence on the statutory factors. In contested cases, a guardian ad litem may be appointed to represent the child's independent interests before the court.

Types of custody in Wyoming

Wyoming recognizes two custody concepts: legal custody and physical custody. Legal custody is the authority to make major decisions about the child's upbringing, including education, non-emergency medical care, and religious instruction. Physical custody refers to where the child resides and when each parent has parenting time. W.S. 20-2-201(d) lets a court combine joint, shared, or sole custody for either element in whatever form serves the child's best interests, with no presumption for or against any form, and the court may assign different arrangements for legal decision-making and physical time. Courts also use the terms primary and secondary residential parent when one parent has substantially more parenting time.

Does Wyoming presume joint or 50/50 custody?

No. W.S. 20-2-201(d) directs that in determining custody "a court shall not favor or disfavor any form of custody," and that custody "shall be crafted to promote the best interests of the children, and may include any combination of joint, shared or sole custody." Wyoming has no rebuttable presumption toward joint, shared, or equal-time custody; the arrangement follows entirely from the best-interests factors below.

Bills to change this have not passed. A 2025 shared-parenting bill, SF0117, which would have required an order of shared custody unless an exception applied, died in the Senate Judiciary Committee on March 3, 2025. A 2026 follow-up, SF0093, which would have required written findings whenever custody is not allocated equally, failed introduction in the Senate on February 11, 2026, by a vote of 19-12 (a budget-session introduction needs a two-thirds vote). W.S. 20-2-201(d) is unchanged.

The court must weigh evidence of spousal or child abuse as contrary to the children's best interests under W.S. 20-2-201(c), and must arrange visitation to protect the children and an abused parent from further harm. Beyond that mandatory consideration, the statute gives the court discretion to craft whatever combination of joint, shared, or sole custody the evidence supports. Unlike several other states, Wyoming has not enacted a statutory presumption of substantially equal parenting time.

One rebuttable presumption does exist in Wyoming custody and visitation law, but it goes to the terms of visitation rather than the form of custody. Under W.S. 20-2-202(b), when a court considers an order for visitation there is a rebuttable presumption that unsupervised visitation is not in a child's best interests where the parent is required to register as a sex offender under W.S. 7-19-301 through 7-19-310. The parent can rebut that presumption with evidence, and the same conviction is separately listed as a best-interests factor under W.S. 20-2-201(a)(x).

The best interests factors Wyoming courts weigh

W.S. 20-2-201 provides a non-exhaustive list of factors Wyoming courts consider when evaluating custody arrangements:

• The quality of the child's relationship with each parent
• Each parent's ability to provide and arrange appropriate care for the child
• Each parent's competency and fitness as a parent
• Each parent's willingness to accept all parenting responsibilities
• Each parent's ability to maintain a loving, stable relationship with the child
• The quality and consistency of parent-child interaction
• Each parent's willingness to allow the other parent to provide care without undue intrusion
• The geographic distance between the parents' homes
• The current physical and mental ability of each parent to care for each child
• Whether either parent has a conviction for which the parent must register as a sex offender under W.S. 7-19-301 through 7-19-310
• Other factors the court finds relevant to the specific case

The list is intentionally non-exhaustive. Domestic violence findings require courts to weigh safety concerns heavily under W.S. 20-2-201(c). The court may also consider the reasonable preferences of a mature child, though no statute sets a specific age at which a child's preference becomes controlling.

Relocation: moving with your child

W.S. 20-2-201 does not address relocation, but W.S. 20-2-202(a)(iii) requires either parent who plans to change their home city or state of residence to give the other parent, and the clerk of district court, written notice at least 30 days before the move, stating the date and destination of the move. Wyoming courts instead treat relocation as potentially significant: a move of substantial distance may constitute a material change in circumstances sufficient to reopen a custody order under W.S. 20-2-204. When relocation is contested, the court considers how the proposed move will affect the child's relationship with both parents, the reason for the move, and whether a modified parenting schedule can preserve meaningful contact with both parents, applying the same best-interests factors used in the original custody determination.

Changing a custody order (modification)

Wyoming allows modification of an existing custody order under W.S. 20-2-204 upon a showing of a material change in circumstances since the prior order was entered, combined with a finding that the modification is in the child's best interest. Wyoming does not impose a mandatory two-year waiting period before modification can be sought. However, courts are generally reluctant to disturb a recently entered order without genuine new circumstances. Common examples of a material change include a parent's relocation, a significant shift in a parent's work schedule, a change in the child's educational or medical needs, a parent's remarriage or cohabitation that materially affects the child, or a change in a child's own preferences as the child matures. Custody arrangements often interact directly with child support obligations; see the Wyoming child support laws page for how parenting time affects support calculations in Wyoming.

If you are facing a custody case in Wyoming

Whether you are filing an original action or responding to one, remember that Wyoming has no presumption toward any particular custody arrangement: the court weighs the best-interests factors independently in every case. If you are seeking equal or substantially shared parenting time, your task is showing the court that arrangement serves the child's best interests on the statutory factors, not relying on any default. Document your involvement in the child's daily life: school activities, medical appointments, meals, and overnights all demonstrate your practical role. Propose a detailed parenting plan specifying legal-custody arrangements and a month-by-month physical-custody calendar. Wyoming encourages mediation to resolve contested matters before trial. Where abuse or relocation is in dispute, have a Wyoming family lawyer shape your parenting plan, starting with a free case evaluation before you file or respond (attorney advertising).

Frequently Asked Questions

How is child custody determined in Wyoming?

Wyoming courts apply the best interests of the child standard under W.S. 20-2-201. The statute directs courts not to favor or disfavor any form of custody, so there is no presumption toward joint, shared, or sole arrangements. Courts weigh factors including each parent's relationship with the child, ability to provide care, willingness to accept parenting responsibilities, fitness, any sex-offender-registration conviction, and geographic distance.

Does Wyoming favor the mother in custody cases?

No. Wyoming custody law is gender-neutral and courts may not favor either parent based on sex. The tender-years doctrine that historically preferred mothers for young children is abolished. Both parents are evaluated under the same best-interests factors, and Wyoming has no presumption toward equal time or any other custody arrangement for either parent.

Is Wyoming a 50/50 custody state?

No. Wyoming has no presumption of 50/50 or equal-time custody. W.S. 20-2-201(d) directs courts not to favor or disfavor any form of custody; the court crafts whatever combination of joint, shared, or sole custody the best-interests factors support, and an equal-time schedule is one possible outcome rather than a statutory default.

At what age can a child choose which parent to live with in Wyoming?

Wyoming has no statute setting a specific age at which a child's preference controls. Courts may consider the reasonable preferences of a child who is old enough to form a considered opinion, but it is one of many factors. A teenager's strong and consistent preference typically carries significant weight, while the stated preference of a young child may be given less weight.

How do I change a custody order in Wyoming?

File a motion in the district court that entered the original order and demonstrate a material change in circumstances since the order was entered, plus that the modification is in the child's best interest under W.S. 20-2-204. Wyoming does not impose a mandatory waiting period before modification can be sought, though courts are reluctant to disturb a recent order without genuine new circumstances.

Can a parent move away with the child in Wyoming?

Yes, with notice. W.S. 20-2-202(a)(iii) requires a parent who plans to change their home city or state of residence to give the other parent, and the clerk of district court, written notice at least 30 days before the move, stating the date and destination of the move. A significant move may also constitute a material change in circumstances sufficient to reopen the custody order under W.S. 20-2-204, and the court applies the same best-interests factors used in the original custody determination.

What is the difference between legal custody and physical custody in Wyoming?

Legal custody is the authority to make major decisions about the child's education, health care, and religion. Physical custody refers to where the child lives and the parenting-time schedule. W.S. 20-2-201(d) lets the court combine joint, shared, or sole custody for each, so a court can award joint legal custody with unequal physical time, or any other combination the evidence supports, with no default toward equal time.
