Yes, alimony can be changed in Oklahoma under Okla. Stat. tit. 43 § 134, but only if you prove a substantial and continuing change in circumstances that makes the original order unreasonable. Oklahoma courts allow modification of periodic support alimony when the paying spouse experiences job loss, disability, or retirement, or when the recipient spouse gains employment, receives inheritance, or begins cohabiting with a romantic partner. Filing fees for modification motions range from $183 to $258 depending on county, and modifications take effect prospectively from the date of the court order, not the date you file your motion.

What Is Alimony Modification in Oklahoma?
Alimony modification in Oklahoma is a legal process that allows either the paying spouse or the receiving spouse to request changes to an existing spousal support order when financial circumstances have significantly changed since the original divorce decree. Under Okla. Stat. tit. 43 § 134, Oklahoma courts have authority to modify the amount, duration, or payment terms of periodic support alimony when the requesting party proves the change is substantial and continuing. Oklahoma law distinguishes between modifiable support alimony and non-modifiable property division payments, making it critical to understand which type of spousal support your divorce decree established.
Oklahoma courts will not modify alimony simply because one party wants a change. The modification standard requires proof that circumstances have changed so significantly that enforcing the original order would be unreasonable to either party. Courts evaluate both the recipient's ongoing need for support and the paying spouse's current ability to pay when deciding whether modification is warranted.
Grounds for Alimony Modification in Oklahoma
Oklahoma law recognizes several grounds that qualify as substantial and continuing changes in circumstances for purposes of alimony modification under Okla. Stat. tit. 43 § 134. The requesting party must demonstrate that the change is significant, ongoing, and not temporary or self-created in bad faith.
Grounds to Reduce Alimony
The paying spouse may seek to reduce spousal support by proving any of the following changes:
- Job loss through termination, layoff, or company closure
- Disability or serious illness reducing earning capacity
- Retirement at a reasonable age in good faith
- Significant income reduction due to economic factors beyond the spouse's control
- Recipient spouse's cohabitation with a romantic partner
- Recipient spouse's increased income or employment
- Recipient spouse's inheritance or windfall
- Recipient spouse's remarriage (triggers automatic termination unless challenged within 90 days)
Grounds to Increase Alimony
The recipient spouse may seek to increase support alimony by demonstrating:
- Unexpected medical expenses or disability reducing earning capacity
- Paying spouse's significant income increase
- Cost of living increases making original award inadequate
- Loss of employment through no fault of the recipient
- Educational or training needs not anticipated in original decree
Cohabitation as Grounds for Modification
Under Okla. Stat. tit. 43 § 134(C), the voluntary cohabitation of the recipient spouse with a member of the opposite sex is a specific statutory ground for modification. Oklahoma law defines cohabitation as dwelling together continuously and habitually in a private conjugal relationship not solemnized as a marriage. Courts may reduce or terminate alimony upon proof of cohabitation combined with a substantial change in either party's circumstances.
Types of Alimony That Can Be Modified
Not all Oklahoma spousal support awards are subject to modification. Understanding which type of alimony your divorce decree established determines whether you can seek changes.
Modifiable Alimony Types
| Type | Definition | Modifiable? |
|---|---|---|
| Support Alimony | Periodic payments for living expenses | Yes |
| Rehabilitative Alimony | Time-limited support for education/training | Yes |
| Temporary Alimony | Pendente lite support during divorce | Yes (retroactively possible) |
Non-Modifiable Alimony Types
| Type | Definition | Modifiable? |
|---|---|---|
| Alimony in Lieu of Property | Lump-sum or fixed payment plan | No |
| Property Division Payments | Division of marital assets | No |
| Consent Decree Alimony | Agreed-upon support amounts | Generally No |
Oklahoma courts distinguish between support alimony ordered after trial and support alimony agreed upon in a consent decree. The Oklahoma Supreme Court in Stuart v. Stuart (1976 OK 107) held that consent decree support awards are final and generally not subject to later modification by the court. Only support alimony ordered by a judge after contested litigation is typically modifiable under 43 O.S. § 134.
How to File for Alimony Modification in Oklahoma
Filing for alimony modification in Oklahoma requires submitting a motion to the district court that issued the original divorce decree, paying applicable filing fees ranging from $183 to $258 depending on county, and serving the motion on your former spouse. The modification process typically takes 3 to 6 months from filing to final order, though contested cases may extend to 12 months or longer.
Step 1: Gather Documentation
Before filing your motion, collect evidence supporting your claimed change in circumstances:
- Last 2 years of tax returns
- Recent pay stubs (last 3-6 months)
- Bank statements (last 3-6 months)
- Medical records if claiming disability
- Employment termination documentation
- Evidence of cohabitation if applicable
- Retirement account statements
- Monthly expense documentation
Step 2: File Motion to Modify
File your Motion to Modify Spousal Support with the district court that issued your original divorce decree. Include:
- Detailed explanation of changed circumstances
- Supporting financial documentation
- Proposed modified payment amount or termination
- Verification under oath
Step 3: Pay Filing Fees
Filing fees for modification motions in Oklahoma vary by county:
| County | Filing Fee |
|---|---|
| Oklahoma County | $224 |
| Tulsa County | $235 |
| Cleveland County | $218 |
| Other Counties | $183-$258 |
Fee waiver applications (In Forma Pauperis) are available for those who cannot afford filing fees. As of May 2026, verify current fees with your local clerk.
Step 4: Serve Your Former Spouse
Arrange service of process on your former spouse:
- In-state service: $40-$75
- Out-of-state service: $75-$150
Step 5: Attend Hearing
The court will schedule a hearing where both parties can present evidence. Be prepared to testify about your changed circumstances and provide documentation.
When Do Alimony Modifications Take Effect?
Oklahoma alimony modifications take effect prospectively from the date the court enters the modification order, not from the date you file your motion, under Okla. Stat. tit. 43 § 134(D). This means you must continue paying the original amount throughout litigation, which can take 3-12 months. Oklahoma appellate courts have consistently held that trial courts lack discretion to make modifications retroactive to the filing date.
This prospective-only rule creates significant financial exposure for paying spouses. If your income drops in January and you file a modification motion that same month, but the court does not enter a modification order until September, you remain obligated to pay the full original amount for those 8 months. Failure to pay during this period accumulates arrearages that cannot be forgiven even after modification.
Exception: Temporary Alimony
Temporary support alimony (pendente lite) awarded during divorce proceedings may be modified retroactively under certain circumstances, as established in Gray v. Gray (1996 OK 84). Courts have discretion to adjust temporary support retroactively if the recipient's needs or paying spouse's ability to pay changed significantly during proceedings.
Termination of Alimony in Oklahoma
Oklahoma law provides several events that automatically terminate alimony obligations without requiring court action, as well as events that require formal termination through the court.
Automatic Termination Events
Alimony payments automatically terminate upon:
- Death of either spouse (claims for unpaid amounts must be filed within 90 days)
- Remarriage of the recipient spouse (unless recipient files motion within 90 days to continue support)
Court-Ordered Termination
The paying spouse may petition for termination based on:
- Recipient's cohabitation with romantic partner
- Recipient's self-sufficiency through employment
- Completion of rehabilitative alimony term
- Other substantial change in circumstances
The 90-Day Rule for Remarriage
Under Okla. Stat. tit. 43 § 134(A), if the recipient spouse remarries, alimony automatically terminates unless the recipient files a motion within 90 days after remarriage to prove that some amount of support is still needed. This 90-day deadline is strictly enforced by Oklahoma courts, and failure to file within this window results in permanent loss of support rights.
What Courts Consider in Modification Cases
Oklahoma courts evaluating alimony modification requests under 43 O.S. § 134 examine whether the change in circumstances is substantial, continuing, and makes the current order unreasonable. Judges apply a balancing test weighing the recipient's current need against the paying spouse's current ability to pay.
Factors Courts Evaluate
- Current income of both parties compared to income at divorce
- Employment status changes and reasons for any changes
- Health and age of both parties
- Earning capacity versus actual earnings (courts may impute income)
- Standard of living established during marriage
- Duration of the marriage
- Property division received by each party
- Good faith nature of claimed changes
Bad Faith Analysis
Oklahoma courts scrutinize whether claimed changes are genuine or manufactured to avoid support obligations. In Parnell v. Parnell (2010 OK CIV APP 74), the court established that if a paying spouse voluntarily quits a well-paying job to take lower-paying work solely to reduce alimony, the court may impute income based on the higher salary the spouse abandoned. Similarly, in Stansberry v. Stansberry (1978 OK 77), courts were directed to evaluate earning capacity—what a spouse could realistically earn with reasonable effort—rather than accepting claimed reduced income at face value.
Income Imputation in Modification Cases
Oklahoma courts have authority to impute income to either party when evaluating modification requests if the court finds the party is voluntarily underemployed or unemployed. Income imputation assigns earning capacity rather than actual earnings when calculating support obligations.
When Courts Impute Income
- Voluntary job loss or resignation without good cause
- Taking lower-paying employment without justification
- Refusing suitable employment opportunities
- Starting a business that generates below-capacity income
- Early retirement before typical retirement age
How Income Is Calculated
Courts typically impute income based on:
- Previous employment earnings
- Education and professional credentials
- Work history and experience
- Job market conditions in the geographic area
- Physical and mental capacity to work
- Age and health limitations
Military Retirement and VA Benefits
Oklahoma law provides special protections for military service members regarding alimony and disability compensation. Under Okla. Stat. tit. 43 § 134, courts cannot consider disability compensation received from the U.S. Department of Veterans Affairs for service-related injuries when calculating or modifying spousal support. This protection applies to both the initial alimony determination and subsequent modification proceedings.
Additionally, courts cannot offset service-related disability income against other assets of the military member. Disposable retired or retainer military pay may be divided or awarded as alimony under federal law (the Uniformed Services Former Spouses' Protection Act), but VA disability benefits remain protected.

| Service of Process | $40-$150 |
| Attorney Hourly Rate | $200-$400 |
