Court System Overview
District Court
Wyoming handles child custody, visitation, and support matters through the District Court system. Wyoming has nine judicial districts covering all 23 counties. District courts have general jurisdiction over all civil matters, including divorce, custody, visitation, child support, and paternity cases. Cases are governed primarily by Wyo. Stat. Title 20, Chapter 2 (Divorce). Wyoming does not have a separate family court division; district court judges hear the full range of domestic relations cases along with other civil and criminal matters.
Legal Custody
Legal custody in Wyoming refers to the right and responsibility to make major decisions regarding the child's welfare, including education, healthcare, and religious upbringing. Under Wyo. Stat. 20-2-201(a), the court may award joint legal custody (both parents share decision-making authority on major issues) or sole legal custody (one parent has the exclusive right to make major decisions). The court considers the best interests of the child when allocating legal custody.
Physical Custody
Physical custody in Wyoming determines where the child primarily resides and the day-to-day care arrangement. The court may award primary physical custody to one parent with visitation rights for the other parent, or joint physical custody where the child spends substantial time with both parents. Wyoming courts establish a visitation schedule, including provisions for holidays, school breaks, and summer. The court has broad discretion to craft an arrangement that serves the child's best interests under Wyo. Stat. 20-2-201.
Presumption
Wyoming law does not establish a statutory presumption in favor of joint or sole custody. Under Wyo. Stat. 20-2-201(a), the court determines custody based on the best interests of the child, with no preference for either parent based on gender. While Wyoming courts have historically favored arrangements that allow the child to maintain a strong relationship with both parents, there is no mandatory presumption of equal time. The court has broad discretion to fashion a custody arrangement appropriate to the specific circumstances of each case.
Best Interest Factors
Wyo. Stat. 20-2-201(a)
The court evaluates the following factors when determining custody arrangements. Each factor represents an area where documented evidence can make a difference.
- 1 The quality of the child's relationship with each parent (Wyo. Stat. 20-2-201(a))
- 2 The ability of each parent to provide adequate care for the child, including food, clothing, shelter, medical care, and a safe environment
- 3 The relative competency and fitness of each parent, including each parent's willingness to accept the responsibilities of parenting
- 4 Each parent's willingness to facilitate and encourage a close and continuing relationship between the child and the other parent
- 5 The stability of the proposed living arrangement and the desirability of maintaining continuity in the child's life
- 6 The mental and physical health of all individuals involved
- 7 Any evidence of domestic violence, child abuse, or substance abuse by either parent (Wyo. Stat. 20-2-201(c))
- 8 The reasonable preference of the child, if the child is of sufficient age and capacity to form an intelligent preference
- 9 Any other factor the court deems necessary and relevant to the determination of custody
Note: Wyoming does not provide an extensive statutory enumeration of best interest factors. Instead, Wyo. Stat. 20-2-201(a) directs the court to consider "all relevant factors" in determining custody. The factors considered are drawn from the statute and from Wyoming Supreme Court case law, including decisions such as Pace v. Pace, Reavis v. Reavis, and Yates v. Yates. The court has broad discretion to weigh any factor it deems relevant. Under Wyo. Stat. 20-2-201(c), if domestic violence is established, there is a rebuttable presumption that the perpetrating parent should not receive sole or joint custody. The court may also appoint a guardian ad litem to represent the child's interests.

Documentation the Court Expects
Wyoming courts expect organized, factual evidence tied to the best interest of the child standard under Wyo. Stat. 20-2-201. Financial affidavits are required for child support calculations. Parents should document their involvement in the child's daily life, their cooperation with the other parent, and the stability of their home environment. If domestic violence or substance abuse is alleged, concrete documentation such as police reports, medical records, and protective order filings is essential.

Filing Process
Step by Step
- 1 Determine jurisdiction: custody actions should be filed in the District Court of the county where the defendant resides, or where the plaintiff resides if the defendant is a nonresident; UCCJEA home state jurisdiction requirements must also be satisfied
- 2 Obtain the required forms from the Wyoming Judicial Branch website or the District Court clerk's office in your county
- 3 Complete the Complaint for Divorce (if custody arises in a divorce) or a Petition for Custody, along with the UCCJEA Affidavit and a Confidential Financial Affidavit
- 4 File the complaint with the Clerk of the District Court and pay the applicable filing fee; if you cannot afford the fee, file a Motion to Proceed In Forma Pauperis requesting a fee waiver
- 5 Serve the other parent with the complaint and summons through the county sheriff, a private process server, or certified mail as permitted under the Wyoming Rules of Civil Procedure
- 6 The respondent has 30 days after service to file an answer or responsive pleading (if served within Wyoming)
- 7 Attend any court-ordered mediation or settlement conference; many Wyoming judicial districts encourage or require mediation in contested custody cases
- 8 If the case is not resolved, attend trial where both parties present testimony and evidence; the judge will enter a custody order based on the best interests of the child under Wyo. Stat. 20-2-201
Required Forms
Typical Timeline
Wyoming requires a mandatory 20-day waiting period from the date of service before a divorce can be granted. Uncontested cases with agreed custody arrangements may be resolved in 2 to 4 months. Contested cases typically take 6 to 12 months or longer depending on the judicial district, the complexity of the issues, and whether the court orders custody evaluations or guardian ad litem investigations. Temporary custody orders can be obtained on an expedited basis when immediate relief is needed.
Self-Represented (Pro Se) Notes
Wyoming allows self-representation in custody cases. The Wyoming Judicial Branch provides a Court Self-Help Center with forms and instructions at courts.state.wy.us. Court clerks can provide forms and general procedural information but cannot give legal advice. Pro se litigants are held to the same rules and deadlines as attorneys. Wyoming Legal Services and the Wyoming State Bar Lawyer Referral Service can assist individuals in finding legal help.

Modifying a Custody Order
What Counts as a Material Change
To modify a custody order in Wyoming, the parent seeking modification must demonstrate a material change in circumstances that has occurred since the entry of the existing order. Under Wyo. Stat. 20-2-204(c), the court may modify a custody decree when there has been a material change affecting the welfare of the child. The change must be something significant that was not contemplated at the time of the original order.
How to File for Modification
File a Petition to Modify Custody in the district court that entered the original order or the court with current jurisdiction. The other parent must be served with the petition. The court evaluates whether a material change in circumstances has occurred and, if so, applies the best interest standard under Wyo. Stat. 20-2-201 to determine whether modification is warranted. Mediation may be ordered before the modification hearing.
Building Your Case Over Time
Document the specific changes in circumstances that have occurred since the last order was entered. Evidence should demonstrate how the current arrangement no longer serves the child's best interests. Common grounds include relocation, changes in the child's educational or health needs, domestic violence, substance abuse, a parent's persistent violation of the custody or visitation schedule, or significant changes in a parent's living situation, employment, or household composition.
Modifications require a documented trail of change.

Key Deadlines & Tips
Deadlines to Know
- 20-day mandatory waiting period from service before a divorce can be granted in Wyoming
- The respondent has 30 days after service to file an answer or responsive pleading (if served within Wyoming)
- The child must have lived in Wyoming for at least six consecutive months to establish home state jurisdiction under the UCCJEA

- Appeals from district court custody orders must be filed with the Wyoming Supreme Court within 30 days of entry of the final order under W.R.A.P. 2.01
Practice Tips for Wyoming
Wyoming courts have broad discretion in custody determinations. Present organized, factual evidence that directly addresses the child's best interests rather than focusing on the other parent's shortcomings.
Document your involvement in your child's daily life, including school activities, medical appointments, meals, bedtime routines, and extracurricular participation. Wyoming courts evaluate each parent's demonstrated commitment to parenting.
If domestic violence is a factor, Wyo. Stat. 20-2-201(c) creates a rebuttable presumption against awarding custody to the perpetrating parent. Obtain a protective order under Wyo. Stat. 35-21-103 and document all incidents thoroughly.
Keep a detailed parenting log recording your visitation time, daily caregiving activities, and any schedule disruptions or missed visits by the other parent. Consistent, timestamped records are persuasive in Wyoming courts.
Wyoming does not set a specific age at which a child can choose which parent to live with. However, the court may consider the reasonable preference of a child who is sufficiently mature to express an intelligent preference.
Consider mediation before trial if your judicial district encourages it. A mediated agreement allows both parents more control over the custody arrangement than a court-imposed order and is often resolved more quickly.
