At a Glance

Residency requirement:
To file for divorce in Wyoming, at least one spouse must have resided in the state for 60 days immediately before filing the complaint (Wyo. Stat. §20-2-107). Alternatively, if the marriage took place in Wyoming, one spouse must have lived in the state continuously from the time of the marriage until filing. There is no separate county residency requirement.
Filing fee:
$70–$160
Waiting period:
Wyoming uses the Income Shares Model to calculate child support under Wyo. Stat. §20-2-304. Both parents' net incomes are combined and applied to statutory child support tables based on the number of children. The total obligation is then divided proportionally between the parents based on each parent's share of the combined income, with the noncustodial parent's share paid to the custodial parent.

Yes, alimony can be changed in Wyoming. Under Wyoming Statute § 20-2-116, either spouse may petition the court to modify spousal support by demonstrating a material and substantial change in circumstances since the original order. Wyoming courts have broad authority to revise alimony amounts, payment terms, or duration when warranted by changed financial conditions. Common qualifying grounds include job loss, income changes exceeding 20%, retirement, disability, or the receiving spouse becoming self-supporting. The filing fee for a modification petition ranges from $85 to $160 depending on the county, and there are no state-provided self-help forms—most petitioners require attorney assistance.

Understanding Wyoming Alimony Modification Law

Wyoming Statute § 20-2-116 grants courts continuing jurisdiction over alimony orders, allowing modification at any time when justified by changed circumstances. The statute specifically provides that after a decree for alimony or other allowance, the court may from time to time, on the petition of either of the parties, revise and alter the decree respecting the amount of the alimony or allowance or the payment thereof. This means Wyoming treats alimony as inherently adjustable rather than fixed, unlike property division which becomes final upon divorce.

The modification standard in Wyoming requires proof of a material and substantial change in circumstances that occurred after the original order. Minor fluctuations in income or temporary setbacks do not qualify. Wyoming courts generally look for changes exceeding 20% in either party's financial situation, or significant life events such as job loss, disability, retirement, or major health issues. The burden of proof falls on the party seeking modification to demonstrate both the change and why it justifies altering the existing order.

Wyoming judges have broad discretion in alimony matters because the state lacks a statutory formula for calculating support. Under W.S. § 20-2-114, courts consider factors including the length of the marriage, each spouse's earning capacity, the standard of living during marriage, and the receiving spouse's ability to become self-supporting. This same discretionary framework applies to modification requests, giving judges flexibility to fashion appropriate remedies based on individual circumstances.

Grounds for Modifying Alimony in Wyoming

Wyoming courts recognize several categories of changed circumstances that may justify alimony modification. A job loss or involuntary termination affecting the paying spouse's ability to meet support obligations constitutes grounds for reduction. The court evaluates whether the job loss was voluntary, how quickly the spouse is seeking new employment, and the realistic prospects for regaining similar income. Deliberately quitting a job to avoid alimony obligations will not succeed—courts can impute income based on earning capacity.

Significant income changes in either direction may warrant modification in Wyoming. If the paying spouse receives a substantial promotion increasing income by 30% or more, the receiving spouse may petition for increased support. Conversely, if the paying spouse's business fails or industry conditions reduce available work, a decrease may be appropriate. Wyoming courts typically require documentation showing the income change is permanent or long-term rather than temporary or seasonal.

Retirement serves as valid grounds for alimony modification when it occurs at a reasonable age and represents a good-faith decision rather than an attempt to avoid obligations. Wyoming courts consider whether the paying spouse reached normal retirement age (typically 62-67), whether retirement was voluntary or forced, and whether the spouse has pension or retirement income that could continue supporting some level of alimony. Early retirement may be scrutinized more carefully.

Disability or serious illness affecting either party can justify modification in Wyoming. If the paying spouse becomes disabled and cannot work at previous capacity, courts may reduce or terminate alimony. If the receiving spouse develops a disability requiring additional care or preventing planned return to workforce, increased support may be warranted. Medical documentation substantiating the condition and its impact on earning capacity is essential.

Wyoming's Unique Remarriage Rule

Wyoming stands apart from most states because remarriage of the receiving spouse does not automatically terminate alimony obligations. Under Wyoming law, the paying spouse must petition the court for modification and demonstrate that the remarriage constitutes a material and substantial change in circumstances. This typically requires showing that the new marriage has improved the recipient's financial situation such that continued support is unnecessary or should be reduced.

The rationale behind Wyoming's approach recognizes that not all remarriages create financial security. If a receiving spouse remarries someone with limited income or significant debt, the remarriage alone may not fundamentally change their financial needs. Wyoming courts examine the actual impact of the remarriage on the recipient's financial circumstances rather than assuming improvement. Factors considered include the new spouse's income and assets, whether the recipient will work outside the home, and whether the new household has combined finances.

To successfully terminate or reduce alimony based on remarriage in Wyoming, the paying spouse should file a petition demonstrating: (1) the receiving spouse has remarried, (2) the remarriage has materially improved their financial position, and (3) continued alimony at current levels is no longer justified. Evidence may include the new spouse's income, lifestyle changes, or the recipient's reduced need for separate income.

Cohabitation as Grounds for Modification

Cohabitation by the receiving spouse may support alimony modification in Wyoming, though it requires demonstrating more than simply living with a romantic partner. Wyoming courts look at whether the cohabitation arrangement functions like a marriage in economic terms. Relevant factors include shared expenses, commingled finances, the duration of cohabitation, and whether the partner provides financial support equivalent to a spouse.

The burden falls on the paying spouse to prove that the cohabitation relationship creates a material and substantial change in the recipient's financial circumstances. Simply showing that the ex-spouse has a boyfriend or girlfriend living in the home is insufficient. Evidence should demonstrate financial benefits flowing from the relationship, such as the partner paying rent, utilities, or other household expenses that reduce the recipient's need for alimony.

Wyoming courts have discretion in cohabitation cases and may reduce rather than terminate alimony if the relationship provides some but not complete financial support. Documentation such as shared lease agreements, joint bank accounts, or testimony about financial arrangements strengthens modification petitions based on cohabitation.

Filing Process for Alimony Modification in Wyoming

The modification process begins with filing a petition in the same Wyoming district court that issued the original divorce decree. The petition must specifically identify the original case, state the current alimony terms, describe the material changes in circumstances, and request specific relief (increase, decrease, or termination). Filing fees range from $85 to $160 depending on the county—Sheridan County and Natrona County charge $160, while other counties range from $70 to $120. As of January 2026, verify current fees with your local clerk.

Wyoming does not provide self-help forms for alimony modification petitions. Unlike divorce filings where standardized packets exist, modification petitions must be drafted from scratch following Wyoming Rules of Civil Procedure. This effectively requires attorney representation for most petitioners, adding $200 to $400 per hour in legal fees. The Wyoming State Bar provides a lawyer referral service at (307) 632-9061 for those seeking representation.

After filing, the petition must be properly served on the other party, typically through the county sheriff or private process server at a cost of $35 to $100. The responding party has 20 days to file an answer. If the parties disagree, the court schedules a hearing where both sides present evidence and testimony. Modification hearings typically occur within 60 to 90 days of filing in most Wyoming counties, though contested cases with extensive discovery may take longer.

Evidence Required for Modification

Successful alimony modification in Wyoming requires substantial documentation proving the changed circumstances. Financial evidence should include tax returns for the past 2-3 years, recent pay stubs, bank statements, and monthly expense worksheets. If claiming job loss, provide termination documentation, unemployment records, and evidence of job search efforts. For disability claims, include medical records, doctor statements about work limitations, and any disability determination letters.

Wyoming courts expect detailed financial disclosure from both parties when considering modification. The petitioner must demonstrate their current financial picture while the responding party must provide information showing their actual needs or ability to pay. Incomplete financial disclosure can result in adverse inferences or denial of modification requests. Both parties should be prepared to produce complete records.

Testimony plays a significant role in Wyoming modification hearings. The petitioner typically testifies about the changed circumstances and their impact. Expert witnesses such as vocational evaluators may be helpful in cases involving questions of earning capacity. Witnesses who can corroborate changes in circumstances, such as employers, doctors, or financial advisors, strengthen modification cases.

Court-Ordered vs. Agreement-Based Alimony

A critical distinction in Wyoming alimony law affects modification rights: court-ordered alimony can be modified under W.S. § 20-2-116, but alimony established through a private settlement agreement may not be subject to court modification. Couples who negotiate alimony terms in a divorce settlement and incorporate those terms into their decree through contract rather than judicial determination surrender the right to later seek court modification.

Wyoming courts treat settlement agreement alimony as a contract between the parties rather than a court order subject to modification. If your original divorce decree incorporates a separation agreement specifying alimony terms, review the agreement language carefully. Terms stating the agreement is "non-modifiable" or that support is "contractual in nature" likely preclude court modification. The only way to change such agreements is through mutual consent of both parties.

Before negotiating any divorce settlement involving alimony in Wyoming, consider whether you want modification rights preserved. If circumstances may change—job security, health conditions, or retirement plans—including language allowing future modification provides flexibility. Conversely, recipients may prefer non-modifiable terms for predictability. Understanding this distinction before signing is essential.

Temporary vs. Permanent Alimony Modification

Wyoming courts may grant temporary modifications when circumstances change suddenly but may be temporary themselves. For example, if the paying spouse is laid off but actively seeking comparable employment, the court may temporarily reduce alimony pending reemployment rather than making a permanent adjustment. Temporary modifications typically include review dates or conditions for restoration of original terms.

Permanent modifications are appropriate when the changed circumstances represent a lasting shift unlikely to reverse. Retirement at appropriate age, permanent disability, or the receiving spouse's attainment of full self-sufficiency warrant permanent adjustment. Courts examine whether the change is truly permanent rather than a temporary setback before eliminating or permanently reducing support.

Termination of alimony permanently ends the obligation with no provision for reinstatement. Wyoming courts terminate alimony when the receiving spouse no longer needs support due to self-sufficiency, remarriage with improved financial circumstances, or the expiration of any time-limited support ordered in the original decree. Once terminated, alimony cannot be reinstated even if circumstances change again.

Modification Timeline and Costs

The timeline for alimony modification in Wyoming depends on whether the case is contested. Uncontested modifications where both parties agree to changed terms may be finalized within 30 to 60 days through submission of a stipulated order. Contested modifications requiring a hearing typically take 3 to 6 months from filing to final order. Complex cases involving extensive financial discovery or disputed facts may extend to 9 months or longer.

Cost ComponentTypical Range
Filing Fee$85-$160
Process Service$35-$100
Attorney Fees (simple)$1,500-$3,500
Attorney Fees (contested)$5,000-$15,000+
Expert Witnesses$500-$2,500
Total (uncontested)$1,500-$4,000
Total (contested)$6,000-$20,000+

Fee waivers are available for those who cannot afford filing costs through the Wyoming Affidavit of Indigency (Self-Help Packet 10), available at wyocourts.gov. Limited scope representation, where an attorney assists with specific tasks rather than full representation, can reduce costs for straightforward modifications.

Enforcing Modified Alimony Orders

Once a modification order is entered, it becomes immediately enforceable. The paying spouse must comply with the new terms from the effective date specified in the order. Until a modification order is entered, the original terms remain in full force—a paying spouse cannot unilaterally reduce payments while modification is pending. Self-help reductions expose the paying spouse to contempt proceedings, which can result in fines or jail time.

Wyoming enforces alimony orders through several mechanisms. Income withholding orders can be served on employers to deduct alimony directly from paychecks. Contempt of court proceedings may result in fines up to $500, jail sentences, or both. Courts may also award attorney fees to the recipient spouse for enforcement actions. Bank account levies and property liens provide additional collection tools.

If your circumstances change and you need to seek modification, continue paying the current amount while your petition is pending. Document the hardship if payments are difficult, but do not stop paying without court authorization. Arrearages accumulated during the modification process remain owed unless the court specifically makes the modification retroactive—a remedy rarely granted in Wyoming.

When Modification Is Not Available

Certain types of alimony or support in Wyoming cannot be modified regardless of changed circumstances. Property division ordered as part of the divorce—even if structured as periodic payments—is not subject to modification. For example, if one spouse owes the other $50,000 payable over five years as property equalization, that obligation continues regardless of income changes because it represents property division rather than support.

Alimony established through settlement agreement and designated as non-modifiable in the agreement cannot be changed by court order. Only mutual agreement of both parties can alter such terms. If your divorce involved a negotiated settlement, review the agreement language to determine whether modification rights exist. Ambiguous language may require court interpretation.

Alimony that has already terminated according to its original terms cannot be reinstated. If a decree provided for three years of alimony and that period has expired, no modification petition can extend it. Similarly, alimony that terminated due to the recipient's remarriage or other terminating event cannot be revived even if the circumstances that caused termination change.

Frequently Asked Questions

How much does it cost to modify alimony in Wyoming?

Wyoming alimony modification costs $1,500 to $4,000 for uncontested cases and $6,000 to $20,000 or more for contested modifications. Court filing fees range from $85 to $160 depending on the county, with process service adding $35 to $100. Attorney fees represent the largest expense at $200 to $400 per hour. Fee waivers are available for those who qualify through the Affidavit of Indigency.

What qualifies as a substantial change in circumstances in Wyoming?

Wyoming courts consider job loss, income changes exceeding 20%, retirement at reasonable age, disability preventing work, serious illness, or the receiving spouse becoming self-supporting as substantial changes. The change must be material (significant enough to affect alimony appropriateness), substantial (more than minor fluctuation), and occurring after the original order. Temporary setbacks generally do not qualify.

Does remarriage automatically end alimony in Wyoming?

No, Wyoming is unique in that remarriage does not automatically terminate alimony. The paying spouse must petition the court for modification under W.S. § 20-2-116 and prove that the remarriage creates a material and substantial change in the recipient's financial circumstances. Courts examine whether the new marriage actually improves the recipient's financial situation before reducing or terminating support.

Can I modify alimony without a lawyer in Wyoming?

Technically yes, but practically difficult. Wyoming provides no self-help forms for alimony modification petitions, unlike divorce filings. You must draft legal pleadings following court rules, properly serve the other party, and present evidence at hearings. The Wyoming State Bar lawyer referral service at (307) 632-9061 can help find representation, and limited scope representation may reduce costs.

How long does alimony modification take in Wyoming?

Uncontested modifications where both parties agree typically finalize in 30 to 60 days. Contested modifications requiring hearings take 3 to 6 months on average, with complex cases extending to 9 months or longer. Courts schedule hearings within 60 to 90 days of filing in most counties. Continue paying the current amount while modification is pending to avoid contempt charges.

Can I stop paying alimony while my modification is pending?

No. Wyoming law requires continued payment at the existing level until a court enters a modification order. Unilaterally reducing or stopping payments exposes you to contempt of court proceedings, which can result in fines up to $500, jail time, and obligation to pay the recipient's attorney fees. The court may make modification effective from the filing date in rare cases, but this is not guaranteed.

What if my alimony agreement says it's non-modifiable?

If your divorce settlement agreement designates alimony as non-modifiable or contractual, Wyoming courts generally cannot modify those terms regardless of changed circumstances. Only mutual agreement between both parties can change such terms. Before signing any settlement, understand that non-modifiable language forfeits your right to later seek court adjustment even if your situation changes dramatically.

Can alimony be modified if my ex is living with someone?

Cohabitation may support modification in Wyoming, but you must prove the living arrangement creates a material financial benefit equivalent to remarriage. Simply having a romantic partner is insufficient. Evidence should demonstrate shared expenses, commingled finances, or the partner providing financial support that reduces your ex-spouse's need for alimony. Courts may reduce rather than eliminate support based on cohabitation.

Is there a time limit for seeking alimony modification in Wyoming?

No statutory time limit exists for seeking modification under W.S. § 20-2-116. You may petition for modification at any time while the alimony obligation remains in effect. However, modification can only be based on changes occurring after the original order—you cannot seek modification based on circumstances that existed but were not disclosed during the original proceedings.

What happens to my alimony modification if I move out of Wyoming?

Wyoming retains jurisdiction over alimony orders issued by Wyoming courts even if both parties relocate. Under the Uniform Interstate Family Support Act (UIFSA), Wyoming courts generally maintain exclusive continuing jurisdiction over their orders. You would typically file your modification petition in Wyoming even if you now live elsewhere. However, if both parties consent or neither party nor the child resides in Wyoming, jurisdiction may shift.
