Can Alimony Change Because of a Change of Income?

Life rarely stays static, and neither do the financial circumstances that shaped your original divorce settlement. Whether you have lost a job, taken a significant pay cut, or seen your income grow substantially since your divorce was finalized, you may be wondering whether your spousal maintenance obligation, or the amount you are receiving, can actually change to reflect your new reality.

Spousal Maintenance Is Not Always Permanent

Arizona law allows spousal maintenance to be modified under certain circumstances, recognizing that both spouses’ financial situations can change meaningfully over time. Whether a modification is actually warranted depends on meeting a specific legal standard, not simply on the fact that circumstances have changed.

Arizona’s Standard for Modifying Spousal Maintenance

To modify an existing spousal maintenance order in Arizona, the person requesting the change generally must show that a substantial and continuing change in circumstances has occurred since the original order was entered. Courts apply this standard carefully, since not every life change qualifies.

What Counts as a “Substantial and Continuing” Change

A substantial and continuing change generally refers to a significant shift in financial circumstance that is not temporary or short-lived. Courts look at whether the change is likely to persist over time, rather than a brief fluctuation in income that may resolve on its own. According to the Arizona Courts’ spousal maintenance guidelines, courts have discretion in evaluating exactly what qualifies, which is why the specific facts of your situation matter significantly.

Changes That Usually Don’t Qualify

Minor income fluctuations like short-term unemployment, or temporary reductions in income generally do not meet the substantial and continuing standard required for a modification. Similarly, a reduction or increase in income may not be substantial enough to trigger a modification. The Court is specifically looking for a meaningful, lasting shift in financial circumstances that will have a continuing impact on the financial resources available to the party; not everyday ups and downs or fluctuations in income.

Income Changes That May Support a Modification

Several types of income changes tend to come up repeatedly in modification cases, though each one is evaluated on its own facts.

Job Loss or Reduced Hours

A genuine, involuntary job loss or a significant, lasting reduction in work hours can potentially support a modification request, particularly when the change substantially affects the paying spouse’s ability to meet their existing obligation. Similarly, when a person loses their job and is unable to find a new job that is paying a similar wage or salary. 

A Significant Raise or New Income Source

If the spouse receiving maintenance experiences a substantial increase in income, whether through a new job, a raise, or a new source of income, this could potentially support a request to reduce or terminate maintenance, depending on the terms of the original order.

Retirement

Reaching a reasonable retirement age and genuinely retiring from full-time work can also potentially support a modification request, particularly when retirement was not already anticipated and accounted for in the original spousal maintenance order.

Voluntary vs. Involuntary Income Reduction

Arizona courts generally distinguish between income changes that happen to a person and income changes a person deliberately causes. An involuntary reduction, such as a layoff or a legitimate business downturn, is far more likely to support a modification than a voluntary reduction, such as leaving a well-paying job for a lower-paying one by choice, or reducing hours without a genuine underlying reason. Courts are generally skeptical of income reductions that appear designed specifically to reduce a spousal maintenance obligation.

When Spousal Maintenance Cannot Be Modified

Not every spousal maintenance order can be changed, regardless of how significant a later income change might be.

Non-Modifiable Agreements (Rule 69)

In some cases, divorcing spouses agree to make spousal maintenance non-modifiable as part of their original settlement, often formalized through a Rule 69 agreement. When maintenance has been designated as non-modifiable in this way, a later change in income generally will not be sufficient grounds to modify the order, regardless of how significant that change may be.

How Remarriage or Cohabitation Affects Maintenance

Under Arizona law, spousal maintenance generally terminates automatically upon the remarriage of the spouse receiving support, unless the parties have agreed otherwise in writing. Cohabitation with a new partner does not automatically terminate maintenance in the same way remarriage does, but it can potentially be raised as a factor relevant to a modification request, depending on the specific circumstances involved.

How the Modification Process Works in Arizona

Modifying spousal maintenance is a formal legal process, not something that happens automatically just because circumstances have changed.

Filing a Petition to Modify

To request a modification, the requesting spouse must file a formal petition with the family court that issued the original order, providing evidence supporting the claimed substantial and continuing change in circumstances. The other spouse then has an opportunity to respond, and the case may proceed through negotiation or, if necessary, a hearing before a judge.

Why Modifications Date Back to Your Filing Date

Modifications in Arizona generally take effect the first day of the month after the petition to modify was filed, not from the date the underlying change in circumstances actually occurred; if you filed on January 31st the modification would be effective February 1st, but if you filed February 1st it would not be effective until March 1st. This makes timing critical. Waiting too long to file after a significant change in income can mean losing out on modification relief for the period before the petition was filed, even if the change had already occurred.

What Not to Do While Seeking a Change

While pursuing a modification, avoid simply stopping payments on your own without a court order approving the change, avoid making major financial decisions, such as voluntarily reducing your income, specifically to influence the outcome of your case, and avoid waiting an extended period after a significant change before filing your petition. Taking these missteps can undermine your credibility with the court and potentially cost you the relief you are seeking.

Frequently Asked Questions

Here are answers to a few of the most common questions clients ask about modifying spousal maintenance.

Can I Stop Paying Alimony If I Lose My Job?

No, you should not simply stop making payments on your own, even after a genuine job loss. You need to file a petition to modify your spousal maintenance order and obtain court approval for any change, since unauthorized non-payment can result in enforcement action against you.

Does My Ex’s Raise Mean I Have to Pay More?

Not automatically. If you are receiving spousal maintenance and your former spouse’s income increases significantly, that alone does not increase your payments. Any change to the existing order requires filing a petition and demonstrating that the increase meets Arizona’s substantial and continuing change standard.

How Long Does a Modification Take?

The timeline for a spousal maintenance modification varies depending on court schedules, whether the parties can reach an agreement, and the complexity of the underlying financial issues. Cases resolved through negotiation typically move faster than those requiring a contested hearing.

Can I File for a Modification Without a Lawyer?

While it is possible to file for a modification without an attorney, spousal maintenance modifications involve specific legal standards and evidentiary requirements that can be difficult to navigate alone. Working with an experienced family law attorney can help ensure your petition is properly supported and presented to the court.
