Yes, alimony can be changed in Oregon. Under ORS 107.135, Oregon courts may modify spousal support when a party demonstrates a substantial and unanticipated change in economic circumstances since the original order was established. The filing fee for a modification motion ranges from $287 to $301 depending on the county, and modifications can be made retroactive to the date the motion was served. Oregon recognizes three types of spousal support—transitional, compensatory, and maintenance—each with different modification standards, with compensatory support requiring the highest burden of proof for changes.

Understanding Oregon Spousal Support Modification Laws in 2026
Oregon permits alimony modification under ORS 107.135 when either the paying spouse (obligor) or receiving spouse (obligee) experiences a substantial change in economic circumstances that was not anticipated at the time of the original divorce judgment. The modification must be filed in the same circuit court that issued the original dissolution of marriage decree, and parties must demonstrate with specific evidence how their financial situation has materially changed since the prior order was entered.
Oregon courts evaluate modification requests by examining multiple financial factors as outlined in ORS 107.105. These factors include the relative income and earning capacity of both parties, changes in employment status, health conditions affecting earning ability, and shifts in reasonable monthly expenses. Courts also consider whether the change was voluntary or involuntary, as voluntary income reduction typically does not justify modification of spousal support obligations.
The Three Types of Spousal Support and Their Modification Standards
Oregon law under ORS 107.105(1)(d) establishes three distinct categories of spousal support, each serving different purposes and carrying different modification standards. Understanding which type of support you have is critical because the legal burden required to modify each type varies significantly.
Transitional Spousal Support Modification
Transitional spousal support in Oregon is designed to help a former spouse re-enter the workforce or advance their career through education and training, typically lasting 1 to 5 years. This type of support is the easiest to modify because courts recognize that transitional circumstances inherently involve changing financial situations. A party seeking to modify transitional support must demonstrate a substantial change in economic circumstances, such as job loss, completion of training programs earlier than anticipated, or inability to find employment despite good-faith efforts.
Common grounds for modifying transitional support include the receiving spouse obtaining full-time employment before the scheduled end date, the paying spouse experiencing involuntary job loss or significant income reduction of 20% or more, unexpected medical expenses preventing either party from meeting their financial obligations, or the receiving spouse failing to make reasonable progress toward self-sufficiency as contemplated by the original order.
Compensatory Spousal Support Modification in Oregon
Compensatory spousal support carries the highest modification standard under Oregon law. Under ORS 107.135, compensatory support may only be modified upon showing an involuntary, extraordinary, and unanticipated change in circumstances that reduces the paying spouse's earning capacity. Regular job changes, expected life events, and normal economic fluctuations typically do not meet this heightened standard because compensatory awards are designed to reimburse one spouse for significant contributions to the other spouse's education, training, or career advancement.
For example, if one spouse worked to put the other through medical school and received compensatory support as reimbursement for that contribution, the paying spouse would need to demonstrate something extraordinary—such as a permanent disability preventing them from practicing medicine—to justify modification. Voluntary career changes, early retirement, or remarriage of the paying spouse generally do not qualify as extraordinary circumstances sufficient to modify compensatory support awards.
Spousal Maintenance Modification Standards
Spousal maintenance, the most common type of alimony in Oregon, requires proof of a substantial and unanticipated change in economic circumstances for modification. Courts evaluate the totality of financial circumstances when considering maintenance modification requests under ORS 107.135. A substantial change in the cost of reasonable and necessary expenses to either party is specifically recognized by statute as sufficient grounds for the court to reconsider its support order.
Oregon courts have held that the following constitute substantial changes justifying maintenance modification: involuntary job loss or layoff resulting in income reduction of 20% or more, permanent disability affecting earning capacity, serious illness requiring substantial medical expenses, the obligee obtaining substantially higher income through employment or inheritance, and retirement at normal retirement age when retirement was not contemplated in the original order.
What Qualifies as a Substantial Change in Circumstances
Oregon courts apply a two-part test when evaluating whether a change in circumstances is substantial enough to warrant spousal support modification. First, the change must be economically significant—minor fluctuations in income or expenses rarely justify modification. Second, the change must have been unanticipated at the time of the original divorce judgment. Changes that were foreseeable or contemplated when the original order was entered typically do not support modification under ORS 107.135.
The following circumstances have been recognized by Oregon courts as substantial changes warranting modification consideration:
- Involuntary termination from employment resulting in 25% or greater income reduction
- Permanent disability certified by medical professionals limiting earning capacity
- Significant increase in the receiving spouse's income (generally 30% or more)
- Retirement at or near normal retirement age (65 or Social Security eligibility)
- Failure to receive anticipated pension or Social Security benefits
- Business closure or bankruptcy affecting income
- Serious medical conditions requiring ongoing treatment expenses
Changes That Do Not Support Modification
Oregon case law has established that certain circumstances do not constitute substantial changes warranting spousal support modification. In a notable Oregon Court of Appeals decision, the court held that an increase in the paying spouse's income combined with a decrease in expenses due to children's emancipation does not constitute a substantial change of circumstances sufficient to modify support obligations. Courts specifically reject modification requests based on voluntary income reduction or underemployment.
The following generally do not justify modification of spousal support in Oregon:
- Voluntary retirement before normal retirement age
- Intentional income reduction to avoid support obligations
- Minor income fluctuations under 15-20%
- Remarriage of the receiving spouse (alone, without proof that remarriage eliminated need)
- Emancipation of children reducing the paying spouse's other expenses
- Normal market fluctuations affecting investment income
- Voluntary career changes to lower-paying positions
How to File for Alimony Modification in Oregon
Filing for spousal support modification in Oregon requires submitting a motion to the circuit court that issued the original divorce judgment, along with payment of the filing fee of $287 to $301 depending on the county. The filing party must complete a motion and supporting affidavit signed under oath that specifically describes the substantial change in circumstances justifying modification. Oregon requires use of approved forms available through the Oregon Judicial Department.
Required Documents and Forms
The Oregon Judicial Department provides a modification packet (form DR-Modif-PACKET-Movant) containing all necessary forms for filing a spousal support modification motion. Required documents include:
- Motion to Modify Judgment (specifying which provisions you seek to modify)
- Supporting Affidavit detailing the substantial change in circumstances with specific facts
- Certificate Regarding Pending Support Proceeding (required by ORS 107.135)
- Financial Declaration showing current income, expenses, assets, and debts
- Proof of service showing the motion was properly served on the opposing party
- Proposed Modified Judgment (form current as of January 2026)
Filing Fees and Court Costs
The filing fee for a spousal support modification motion in Oregon ranges from $287 to $301 depending on the county where you file. As of March 2026, the most commonly cited statewide figure is $301, though some counties charge $287. Parties who cannot afford the filing fee may request a fee waiver or deferral by completing the Fee Deferral or Waiver Application and Declaration form, with eligibility based on household income and financial hardship.
Additional costs beyond the filing fee include: process server fees of $30 to $150 for serving the motion on the other party, attorney fees ranging from $3,000 to $10,000 for contested modification cases, and certified copies of modified judgments at $5 to $25 each. Uncontested modifications where both parties agree typically cost $1,500 to $3,500 in legal fees.
Retroactive Modification of Spousal Support
Oregon law allows modified spousal support to be applied retroactively, but only to the date the modification motion was served on the other party or any date thereafter. Under ORS 107.135, the court cannot modify any portion of the judgment regarding payments that have accrued before the motion is served. This means unpaid support that accumulated before filing remains due regardless of the modification outcome.
For example, if your circumstances changed in January but you did not file and serve your modification motion until April, you remain responsible for the original support amount for January, February, and March. The modified amount can only apply starting from April when the motion was served. Oregon courts have discretion to set the effective date anywhere from the service date to the final judgment date, as established in Duvall and Duvall (26 Or App 99, 1976).
Non-Modifiable Spousal Support Agreements
Oregon law permits divorcing parties to agree that spousal support shall be non-modifiable, but such agreements must contain specific waiver language in the divorce judgment. Under ORS 107.104, if the parties agree to preclude or limit modification of all or any portion of a spousal support award, that provision becomes binding on the court. The divorce judgment must contain explicit language waiving the right to seek modification for the non-modifiable provisions to be enforceable.
Parties considering non-modifiable support should understand that this waiver applies regardless of future circumstances. Even if the paying spouse becomes permanently disabled or the receiving spouse wins the lottery, a valid non-modifiable provision generally cannot be changed. However, non-modifiable spousal support provisions typically do not survive the death of either party unless the agreement specifically provides for continuation of payments from the estate.
Termination of Spousal Support in Oregon
Spousal support in Oregon automatically terminates upon the death of either party unless the original divorce judgment provides otherwise. Remarriage of the receiving spouse creates grounds for modification or termination, but does not automatically end support obligations. Under Oregon case law, remarriage alone does not automatically justify termination—the paying spouse must demonstrate that the remarriage has rendered the reasons for the original support award unnecessary.
If you seek to terminate spousal support based on the receiving spouse's remarriage, you must file a motion showing that the new spouse's income and contributions to household expenses have substantially reduced or eliminated the former spouse's need for support. Courts examine the receiving spouse's total household income and expenses post-remarriage to determine whether continued support is justified.
Reinstatement of Terminated Support
Oregon is one of the few states that allows reinstatement of previously terminated spousal support under ORS 107.136. If support was terminated based on circumstances that no longer exist, the receiving spouse may petition for reinstatement of the remaining duration and amount of the original award. The moving party must prove that the basis for termination has ceased to exist and that reinstatement is just and equitable under all circumstances.
Oregon Residency Requirements for Modification
To file a spousal support modification in Oregon, you must file in the circuit court that issued the original divorce judgment, typically in the county where either party resides. Under ORS 107.075, Oregon has a two-tier residency system for divorce jurisdiction. If the original marriage was solemnized in Oregon, no minimum residency period is required. If the marriage occurred outside Oregon, at least one party must have been an Oregon resident for 6 months continuously before filing.
For modification motions specifically, the original court that issued the divorce judgment retains jurisdiction over modifications. If both parties have moved out of the county where the divorce was granted, you may be able to request transfer of the case to a more convenient venue, though this adds procedural complexity and potential delays.
Tips for a Successful Modification Request
To maximize your chances of obtaining a favorable spousal support modification in Oregon, gather comprehensive documentation of your changed circumstances before filing. Courts require specific evidence showing how and when your financial situation changed, comparing current circumstances to those at the time of the original divorce judgment. General statements about financial difficulty are insufficient—you must provide concrete proof.
