Wyoming Divorce Laws (2026): Grounds, Residency, and Process

To get divorced in Wyoming, at least one spouse must prove irreconcilable differences, which is the primary no-fault ground under Wyoming law. One party must have been a Wyoming resident for 60 days before filing. No separation period is required, and a 20-day waiting period applies after filing before a decree can enter.

Grounds for divorce in Wyoming

Wyoming recognizes two grounds for divorce. The primary ground is irreconcilable differences, as established by Wyo. Stat. 20-2-104. The second ground is incurable insanity of one spouse accompanied by at least two years of confinement in a mental institution.

Wyoming has no fault-based divorce grounds. You cannot obtain a divorce in Wyoming by proving adultery, cruelty, desertion, or other marital misconduct. The entire focus is on whether the parties have irreconcilable differences that make continuation of the marriage impractical.

Irreconcilable differences does not require proof that the marriage has failed for a particular length of time. One spouse can assert that differences exist, and the court accepts that assertion as sufficient. Unlike some states, Wyoming does not require both spouses to agree, so one party can pursue the divorce even if the other opposes it.

Because fault plays no role in the divorce itself, Wyoming courts do not consider marital misconduct when deciding whether to grant the divorce. Misconduct may, however, be considered in alimony and property determinations in some circumstances.

Residency requirement

To file for divorce in Wyoming, at least one party must have been a Wyoming resident for 60 consecutive days before the divorce petition is filed (Wyo. Stat. 20-2-107). There is an exception: if the parties were married in Wyoming and one spouse has been a resident since the marriage, no minimum duration applies.

The 60-day requirement is shorter than the 6-month threshold many other states impose, making Wyoming relatively accessible for recent transplants. The statute does not impose a separate county residency requirement; filing in any Wyoming District Court where a party resides is sufficient.

Wyoming has no explicit provision shortening the residency period for military service members stationed in the state, but service members who are domiciled in Wyoming or who maintain Wyoming as their legal residence satisfy the requirement.

Waiting period and separation

Wyoming imposes a 20-day waiting period after the divorce petition is filed before the court can enter a final decree (Wyo. Stat. 20-2-108). This period cannot be waived by agreement, even in uncontested cases where both parties are ready to proceed immediately.

The 20-day wait is among the shortest mandatory cooling-off periods in the country, and it makes Wyoming one of the faster states for finalizing an uncontested divorce. The filing date, not the service date, starts the 20-day clock.

The waiting period is not a separation requirement. Wyoming does not require spouses to live apart before or during the divorce. You may file for divorce while sharing a household, and nothing in Wyoming law requires you to move out or stop living together before the case is heard. Many straightforward uncontested divorces in Wyoming resolve within 1 to 3 months from the filing date.

How property is divided

Wyoming is an equitable distribution state. Unlike the nine community property states (Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin), Wyoming does not presume that each spouse automatically owns half of what was acquired during the marriage. Instead, the court divides marital property fairly based on the specific facts of each case.

Equitable distribution does not mean equal distribution. A court will consider factors such as the length of the marriage, each spouse's economic circumstances and earning capacity, contributions to the marital estate (including homemaking and child-rearing), the value of separate property each party retains, and any other relevant considerations.

Marital property generally includes wages, real estate, and other assets acquired during the marriage using marital funds. Separate property, which includes assets owned before the marriage, gifts given specifically to one spouse, and inheritances, is generally not subject to division. However, separate property that was commingled with marital assets or improved using marital funds can lose its separate character over time.

Wyoming courts have broad discretion in property division. Spouses can also negotiate their own property settlement agreement as part of the divorce, which the court will typically approve if it appears fair and voluntary.

Alimony, custody, and child support

Wyoming courts address alimony (called "maintenance" or "spousal support"), child custody, and child support within or alongside the divorce proceeding.

Alimony is governed by Wyo. Stat. 20-2-114. Wyoming courts have discretion to award alimony based on the financial needs of the requesting spouse and the other spouse's ability to pay. Relevant factors include the length of the marriage, the standard of living during the marriage, each party's earning capacity, age, and health. Wyoming does not have a fixed formula for calculating spousal support, so awards vary widely. For a full discussion see the Wyoming alimony laws page at /us-laws/alimony/wyoming-alimony-laws.

Child custody in Wyoming is governed by Wyo. Stat. 20-2-201. The court decides legal custody (decision-making authority) and physical custody (where the child lives) based on the best interests of the child. Factors include the quality of the relationship each parent has with the child, each parent's fitness, the child's school and community ties, and the willingness of each parent to facilitate a relationship with the other parent. See the Wyoming child custody laws page at /us-laws/child-custody/wyoming-child-custody-laws for details.

Child support is calculated under Wyoming's income shares model, which considers both parents' incomes and the number of children. Estimate your payment with our Wyoming child support calculator. Deviations from the guidelines are allowed with written findings. Support continues until the child turns 18 or graduates from high school, whichever is later. For more, see the divorce laws hub.

How to file for divorce in Wyoming

The divorce process in Wyoming follows a standard sequence. Here is what to expect.

First, confirm that you or your spouse has been a Wyoming resident for at least 60 days. If not, wait until the requirement is met.

Second, prepare your divorce petition and other required forms. Wyoming's self-help resources are available through the Wyoming Judicial Branch website at courts.state.wy.us. You will file the petition and a summons in the District Court for the county where you reside.

Third, pay the filing fee at the court clerk's office. Filing fees vary by county and case type. Fee waivers are available if you qualify based on income.

Fourth, serve your spouse with the summons and petition. Personal service by a process server or the sheriff is the standard method. Your spouse then has 20 days to file a response.

Fifth, exchange financial disclosures. Both parties must provide information about income, assets, debts, and expenses. If children are involved, proposed parenting plans and child support worksheets are also exchanged.

Sixth, negotiate a settlement agreement covering property division, alimony (if any), and parenting arrangements, or prepare for a contested hearing. Wyoming courts encourage mediation for custody disputes.

Seventh, once the 20-day waiting period has passed and all issues are resolved, the court schedules a final hearing. The judge reviews the settlement agreement or, in a contested case, hears testimony and makes findings. When the judge signs the decree of divorce, the marriage is legally dissolved.
