Can Spousal Support Be Modified in California?
Yes — unless the parties have agreed in a written marital settlement agreement that spousal support is non-modifiable, California courts retain jurisdiction to modify spousal support orders when there has been a material change in circumstances. The right to request modification belongs to both the paying spouse and the receiving spouse.
What Qualifies as a Changed Circumstance?
California courts require a showing of material changed circumstances since the original support order was made. Common qualifying changes include:
- Significant change in income. The paying spouse loses their job, takes a substantial pay cut, or becomes disabled. The receiving spouse gets a new job, a significant promotion, or begins earning substantially more than anticipated.
- Remarriage of the supported spouse. Under California Family Code §4337, spousal support terminates automatically upon the supported spouse's remarriage — no court order is needed.
- Cohabitation of the supported spouse. If the supported spouse is living with a new partner in a relationship similar to marriage, the paying spouse can seek reduction or termination of support (Family Code §4323).
- Supported spouse becomes self-supporting. If the supported spouse has achieved the self-sufficiency goal contemplated in the support order, reduction or termination may be appropriate.
- Health changes. A significant change in either party's health that affects earning capacity or need.
How to File for Modification
To request a modification of spousal support, file a Request for Order (FL-300) with an updated Income and Expense Declaration (FL-150). The request must describe the changed circumstances and what modification you are seeking. The other party has the right to file a response and appear at the hearing.
Courts will review both parties' current financial circumstances and determine whether the change is substantial enough to justify modifying the existing order, and if so, what the appropriate new amount should be.
Retroactivity of Support Modifications
An important limitation: California courts generally cannot modify support retroactively to a date before the filing of the Request for Order. This means that if your circumstances change and you delay filing, you may continue to owe (or fail to receive) the original support amount for the entire period of delay. Filing promptly when circumstances change is critical.
