How Does Divorce With Children Work in Wyoming?
Divorce with children Wyoming cases proceed through a single no-fault track that resolves custody, support, and property in one decree. One spouse must have lived in Wyoming for 60 days before filing under Wyo. Stat. § 20-2-107, and no decree becomes final until 20 days pass under § 20-2-108.
A parent begins by filing a Complaint for Divorce in the district court of the county where either spouse lives. Wyoming has no separate county residency requirement, so venue is flexible. The filing spouse pays a fee of $120 to $160 and serves the other parent, who then has 20 days to answer if served inside Wyoming, or 30 days if served in another state. When minor children are involved, the court will not finalize the case until custody, a parenting plan, and child support are resolved. Judges may order both parents to attend a parenting class to lessen the effects of divorce on children, a step expressly authorized under Wyo. Stat. § 20-2-201. Uncontested cases with agreed paperwork can finalize on day 21.
What Is Wyoming's Residency Requirement for Divorce With Children?
Wyoming requires one spouse to have resided in the state for 60 days immediately before filing the complaint, under Wyo. Stat. § 20-2-107. Alternatively, if the marriage was solemnized in Wyoming, a spouse who has lived there continuously from the marriage until filing also qualifies. This is one of the shortest residency rules in the nation.
The statute makes residency straightforward for divorcing parents. A married person who resides in Wyoming when filing is treated as a resident even if the other spouse lives in another state. This matters in custody cases because the parent who establishes Wyoming residency can file locally, and the Wyoming court then gains continuing jurisdiction over custody under Wyo. Stat. § 20-2-203, subject to the Uniform Child Custody Jurisdiction and Enforcement Act. The 60-day clock counts the days physically present in Wyoming before the complaint is filed, not after. There is no waiting period for children to establish their own residency; the parent's 60 days controls the divorce filing, while UCCJEA home-state rules (generally 6 months) govern which state decides custody.
What Is Wyoming's Shared Custody Presumption (2025 Law)?
Wyoming now applies a rebuttable presumption of shared custody, enacted by Senate File 0117 and effective July 1, 2025, amending Wyo. Stat. § 20-2-201. Shared custody means joint legal custody plus joint physical custody, with children residing with each parent for substantially equal time unless a listed exception applies.
This is the single most important change for any divorce with children Wyoming parents now face. Before SF0117, judges weighed best-interest factors with no default. Today, the court must order shared custody unless one of five exceptions is proven. The exceptions are: (1) the parties agreed in writing to a different arrangement; (2) one party was adjudged guilty of a crime involving domestic violence against the other; (3) one party was adjudged guilty of cruelty, abuse, neglect, or mistreatment of the children; (4) the parents no longer reside within 300 miles of each other and a different arrangement is the only practical option; or (5) clear and convincing evidence shows a different arrangement serves the children's best interests. The court still may not prefer one parent based on gender, and it must order custody in well-defined terms to promote compliance.
How Are Custody Decisions Made Under the Best-Interests Standard?
Even with the shared custody presumption, Wyoming courts decide custody under the best-interests standard in Wyo. Stat. § 20-2-201. When a party rebuts the presumption with clear and convincing evidence, the judge weighs statutory factors and may order any combination of joint, shared, or sole custody. Courts cannot favor or disfavor any form of custody as a starting point.
The statute directs judges to consider the geographic distance between the parents' residences, the current physical and mental ability of each parent to care for each child, and whether either parent must register as a sex offender. The court also considers any other relevant factors it deems necessary. Evidence of spousal abuse or child abuse is treated as contrary to the children's best interests, and where family violence has occurred, the court must structure visitation to protect both the children and the abused spouse from further harm. Wyoming distinguishes legal custody (authority over major decisions on education, health, and religion) from physical custody (where children live day to day). A typical contested custody case in Wyoming costs $8,000 to $20,000 in attorney fees, while an uncontested agreed parenting plan can keep total costs near the $120-$160 filing fee.
How Does Wyoming Calculate Child Support for Children?
Wyoming calculates child support using the income shares model under Wyo. Stat. § 20-2-304, combining both parents' net monthly incomes against a statutory table. At $5,000 combined net monthly income, the presumptive obligation is roughly $693 for one child and $1,046 for two children, divided between parents in proportion to income.
Net income equals gross income minus federal, state, and local taxes, FICA, mandatory retirement contributions, union dues, and health insurance premiums. Gross income includes wages, salaries, commissions, bonuses, self-employment earnings, and investment income. The model assumes a child should receive the same proportion of parental income they would have received had the parents stayed together. If one parent earns 60% of combined income, that parent pays 60% of the table obligation. Shared custody changes the math: when each parent keeps the children overnight for more than 25% of the year and both contribute substantially to expenses, the total obligation is multiplied by 150% and then divided proportionally, under Wyo. Stat. § 20-2-304. A self-support reserve protects low-income obligors at the federal poverty line for one person. Courts treat the calculated figure as presumptive and may deviate only under § 20-2-307.
What Goes in a Wyoming Parenting Plan?
A Wyoming parenting plan is the written document defining custody, the residential schedule, and decision-making authority for the children. Under Wyo. Stat. § 20-2-201, the court must order custody in well-defined terms to promote understanding and compliance, which makes a detailed parenting plan essential in every divorce with children Wyoming families file.
A strong parenting plan addresses the regular weekly schedule, holiday and summer rotations, transportation and exchange logistics, and how parents share major decisions about education, health care, and religion. With the 2025 shared custody presumption favoring substantially equal time, many plans now use week-on/week-off or 2-2-3 schedules that split overnights close to 50/50. The plan should also include a communication protocol, a method for resolving disputes (often mediation before returning to court), and a relocation clause. Relocation deserves special attention: moving more than 300 miles from the other parent directly triggers an exception to the shared custody presumption and will likely require a court hearing. Parents who agree in writing can opt out of shared custody, so a clearly signed parenting plan controls the outcome and protects both co-parenting arrangements from later disputes.
What Is the Timeline From Filing to Final Decree?
A Wyoming divorce with children takes a minimum of 21 days because of the mandatory 20-day waiting period in Wyo. Stat. § 20-2-108. Uncontested cases with an agreed parenting plan and child support worksheet can finalize on day 21, while contested custody cases commonly take 6 to 12 months or longer.
| Stage | Uncontested | Contested |
|---|---|---|
| File complaint + pay fee | Day 1 | Day 1 |
| Serve other parent | Days 1-5 | Days 1-10 |
| Response window | 20 days (in-state) | 20-30 days |
| Mandatory waiting period | 20 days (concurrent) | 20 days (minimum) |
| Mediation / temporary orders | Not required | 1-4 months |
| Discovery + custody evaluation | None | 3-9 months |
| Final decree | Day 21 | 6-12+ months |
The 20-day waiting period runs concurrently with the response window, so a cooperative couple loses no extra time. The biggest timeline driver in cases with children is whether the parents accept the shared custody presumption or litigate one of the five exceptions. Custody evaluations, when ordered, add several months. Verify current scheduling with your local district court clerk.
How Much Does a Divorce With Children Cost in Wyoming?
The baseline cost is the filing fee of $120 to $160, plus roughly $35 for sheriff service of process and $25-$75 per parent for court-ordered parenting classes. Total costs range from under $300 for a fully agreed uncontested divorce to $8,000-$20,000 for a contested custody battle requiring attorneys and evaluations.
Wyoming sets filing fees at the county district court level. The statutory base fee is $120 under Wyo. Stat. § 5-3-206, while Natrona and Sheridan counties charge $160, which includes court automation and indigent legal services allocations. There is no fee for the responding spouse to file an answer. Parents who cannot afford the fees can request a waiver using Packet 10 in the Wyoming Family Law self-help forms, available at wyocourts.gov. Beyond filing, the major cost variable is conflict over the children: an agreed parenting plan keeps expenses minimal, while contested custody, guardian ad litem appointments, and custody evaluations drive costs into the thousands. As of June 2026, verify exact figures with your local clerk, because fees vary by county and change periodically.
