Yes, alimony can be changed in California. Under California Family Code § 3651, either the paying spouse or the receiving spouse may request a modification or termination of spousal support at any time by demonstrating a material change in circumstances since the last order. California courts evaluate modification requests using the same 14 factors outlined in Family Code § 4320, including changes in income, employment status, health, and the supported spouse's progress toward self-sufficiency. The filing fee for a spousal support modification motion is $60 as of January 2026, and hearings typically occur 30-45 days after filing.

What Qualifies as a Material Change in Circumstances
California courts require a substantial, ongoing shift in the financial balance between former spouses to justify modifying spousal support. A material change means more than a temporary fluctuation; it must represent a permanent or long-term alteration affecting either the paying spouse's ability to pay or the receiving spouse's financial needs. Courts will not grant modifications based on short-lived circumstances or voluntary changes made to avoid support obligations.
Changes That Typically Qualify for Modification
California courts have recognized the following as valid grounds for alimony modification:
- Job loss or layoff beyond the paying spouse's control
- Long-term disability or serious illness affecting earning capacity
- Retirement at a customary age (typically 65-67)
- Supported spouse obtaining employment or completing vocational training
- Significant promotion or raise for either party
- Supported spouse's cohabitation with a new partner
- Substantial increase in living expenses due to medical needs or caregiving responsibilities
- Change in custody arrangements affecting childcare obligations
Changes That Do Not Qualify
Voluntary underemployment, quitting a job without cause, or intentionally reducing income to avoid spousal support obligations will not persuade a California court to reduce support. Similarly, courts will not modify support based on the paying spouse's dissatisfaction with the original order or general complaints about fairness. The court evaluates whether circumstances have genuinely changed, not whether the original order was ideal.
The 14 Factors California Courts Evaluate Under Family Code 4320
When reviewing a spousal support modification request, California courts must consider the same 14 factors used in the original support determination. Under Family Code § 4320, judges weigh each factor to determine whether the existing support order remains appropriate given changed circumstances. These factors address earning capacity, financial needs, and the practical realities of each party's situation.
Complete List of Family Code 4320 Factors
- The extent to which each party's earning capacity maintains the marital standard of living
- The marketable skills of the supported party and job market demand for those skills
- Time and expenses required for the supported party to acquire education or training
- Impact of unemployment during marriage for domestic duties on the supported party's future earning capacity
- Contributions by the supported party to the other spouse's education, training, or career
- The supporting party's ability to pay, considering income, assets, and standard of living
- Each party's needs based on the standard of living established during marriage
- Obligations and assets of each party, including separate property
- The supported party's ability to work without interfering with dependent children's interests
- Age and health of both parties
- Documented history of domestic violence
- Tax consequences of spousal support (now affected by SB 711 for orders after January 1, 2026)
- Balance of hardships between the parties
- The goal that the supported party become self-supporting within a reasonable time
How to File for Spousal Support Modification in California
Filing for alimony modification in California requires submitting specific forms to the family court that issued your original support order. The process involves completing financial disclosures, gathering evidence of changed circumstances, and attending a court hearing. Most modification hearings are scheduled 30-45 days after filing, though contested cases may take longer.
Step 1: Complete the Required Forms
You must file the following Judicial Council forms:
- FL-300 (Request for Order): The primary motion form explaining what modification you seek and why
- FL-150 (Income and Expense Declaration): A detailed financial disclosure showing current income, expenses, assets, and debts
- FL-349 (Spousal, Partner, or Family Support Attachment): Documents your analysis of the Family Code 4320 factors (submit at least 30 days before trial)
Step 2: Gather Supporting Documentation
Courts require evidence proving the material change in circumstances. Essential documents include:
- Last three months of pay stubs or proof of income change
- Most recent federal and state tax returns (typically 2 years)
- Evidence of job loss (termination letter, unemployment benefits documentation)
- Medical records if disability or illness is the basis for modification
- Proof of cohabitation if seeking reduction based on supported spouse's living arrangements
- Documentation of retirement (Social Security statements, pension documents)
Step 3: File and Serve
File your completed forms with the family court clerk and pay the $60 filing fee. If you cannot afford the fee, request a fee waiver using Form FW-001. After filing, you must serve the other party with copies of all filed documents at least 16 court days before the scheduled hearing (plus additional days for service by mail).
Step 4: Attend the Hearing
Both parties appear before a family court judge who reviews the evidence and arguments. The judge may issue a ruling at the hearing or take the matter under submission for a written decision. If the court finds a material change in circumstances, it will apply the Family Code 4320 factors to determine the new support amount.
The 10-Year Marriage Rule and Ongoing Jurisdiction
Under California Family Code § 4336, marriages lasting 10 years or longer are considered long-term marriages, giving the court indefinite jurisdiction over spousal support. This does not guarantee lifetime support but means the court retains authority to modify or terminate support at any time based on changed circumstances. For short-term marriages (under 10 years), support duration is generally limited to half the length of the marriage, though courts have discretion to extend this period.
Long-Term Marriage (10+ Years)
For marriages of 10 years or more, the court does not set a termination date for spousal support at the time of divorce. Either party may return to court at any point to request modification or termination. The supported spouse may request an increase if financial needs grow, while the paying spouse may request a decrease or termination if the supported spouse becomes self-supporting or circumstances otherwise change.
Short-Term Marriage (Under 10 Years)
Support orders in short-term marriages typically include a termination date, often calculated as half the marriage length. For example, a 6-year marriage might result in a 3-year support order. However, courts can deviate from this guideline based on the Family Code 4320 factors. Once the termination date passes, support ends automatically unless the supported spouse files a motion to extend before expiration.
Automatic Termination: Remarriage and Death
Under California Family Code § 4337, spousal support automatically terminates when the supported spouse remarries or either party dies. This termination occurs by operation of law, meaning no court order is required. The paying spouse's obligation ends on the exact date of remarriage, even if they are not immediately informed of the marriage. However, parties may waive this automatic termination by including explicit language in their written settlement agreement.
Remarriage Terminates Support Automatically
The remarriage must be a valid legal marriage under California law. A commitment ceremony, domestic partnership, or cohabitation does not trigger automatic termination under Family Code 4337. If the supported spouse obtains a valid marriage license and completes a ceremony officiated by an authorized person, support ends that day regardless of whether the paying spouse files a motion.
Cohabitation Creates a Rebuttable Presumption
When the supported spouse cohabits with a romantic partner, Family Code § 4323 creates a rebuttable presumption that their need for support has decreased. This presumption shifts the burden to the supported spouse to prove their financial needs have not actually decreased. Unlike remarriage, cohabitation does not automatically terminate support; instead, the paying spouse must file a motion requesting modification or termination based on the cohabitation.
2026 Tax Law Changes Affecting Spousal Support (SB 711)
California Senate Bill 711, signed into law on October 1, 2025, eliminates the state tax deduction for spousal support payments made under orders dated January 1, 2026, or later. For orders issued before this date, the previous tax treatment continues: paying spouses may deduct support payments on their California state taxes, and receiving spouses must report payments as taxable income. This change aligns California with federal tax law, which eliminated the spousal support deduction in 2019.
How SB 711 Affects Modification Requests
If you modify a pre-2026 support order after December 31, 2025, the original tax treatment applies unless your new order explicitly adopts the post-2026 rules. This means parties modifying existing orders should carefully consider whether to maintain the pre-2026 tax structure or opt into the new rules. The tax impact can significantly affect the net value of support to both parties and may be a relevant factor in modification negotiations.
Practical Impact on Support Calculations
Under the old rules, a $3,000 monthly spousal support payment might have a net cost of approximately $2,100 to the paying spouse (assuming a 30% effective state and federal tax rate) while providing approximately $2,100 in after-tax income to the receiving spouse. Under the new rules, the $3,000 payment costs the full $3,000 to the payer and provides the full $3,000 to the recipient. Courts and attorneys may adjust requested support amounts to account for these changed tax consequences.
Non-Modifiable Spousal Support Agreements
Under Family Code § 3651(d), spousal support may be made non-modifiable by written agreement between the parties. If your divorce settlement includes language stating that support is "non-modifiable as to amount and duration," neither party can later petition the court to change the support terms regardless of changed circumstances. Courts strictly enforce these provisions, so parties should carefully consider whether to include non-modification language before signing a settlement agreement.
What Non-Modifiable Means
A non-modifiable support order locks in both the payment amount and the duration. Even if the paying spouse loses their job or the receiving spouse wins the lottery, the court cannot change the support terms. The only exceptions are the automatic terminations under Family Code 4337 (remarriage or death), which apply unless the parties also waived that provision in their agreement.
Partial Non-Modification Clauses
Some agreements make support non-modifiable as to amount but modifiable as to duration, or vice versa. Others set floors or ceilings (for example, support can never drop below $1,500/month or exceed $4,000/month). Courts will enforce these partial restrictions as written. If considering such provisions, consult with a California family law attorney to understand the long-term implications.
No Retroactive Modifications in California
California law prohibits retroactive modification of spousal support. Under Family Code § 3653, any support that has already accrued as of the date you file your modification request cannot be reduced or eliminated, even if the court grants your modification going forward. Past-due support (arrears) remains a fixed debt that the court cannot forgive. This rule makes timely filing critical: if your circumstances change, file a modification request immediately rather than waiting.
Arrears Cannot Be Reduced
If a paying spouse owes $10,000 in back spousal support at the time they file a modification request, that $10,000 remains owed even if the court reduces or eliminates future payments. The court may set up a payment plan for arrears but cannot reduce the total owed. Interest also accrues on unpaid support at the legal rate of 10% per year.
File Immediately Upon Change
Because modifications only apply prospectively, delaying a modification request can be costly. If a paying spouse loses their job and waits six months to file for modification, they will owe the full original support amount for those six months regardless of their inability to pay. Courts strongly encourage parties to file promptly when circumstances change.
