The Short Answer
Temporary spousal support is generally ordered while a divorce, legal-separation, or other qualifying case is pending. Courts often use a local guideline calculation as a starting point to address immediate need and ability to pay.
Long-term spousal support is ordered at or after judgment. California has no single statewide formula for it. The court must consider every applicable factor in Family Code section 4320 and determine an amount and duration that are just and reasonable under the circumstances.
Temporary Support: Stability While the Case Is Pending
Family Code section 3600 authorizes a court to order support during a pending dissolution or legal-separation proceeding. A spouse may request temporary support after the case starts, and the court may later change the order when finances materially change.
California Courts identifies a common temporary-support guideline as 40% of the higher earner’s net monthly income minus 50% of the lower earner’s net monthly income. That is an educational example, not a universal rule. Local court practices vary; child support and other circumstances may affect the calculation; and a judge can depart from the guideline when the facts justify a different result.
Long-Term Support: The Section 4320 Analysis
At judgment, the court does not simply carry forward a temporary guideline number. Family Code section 4330 directs the court to determine a just and reasonable order based on the marital standard of living and the section 4320 circumstances.
Those circumstances include:
- Each party’s earning capacity and the supported party’s marketable skills, job market, education, and training needs
- The extent to which unemployment or reduced employment during the marriage affected earning capacity
- Contributions to the other spouse’s education, training, career, or license
- The supporting party’s ability to pay, including income, assets, earning capacity, and standard of living
- Each party’s needs measured against the marital standard of living
- Obligations and assets, the duration of the marriage, age and health, and documented evidence of domestic violence
- The immediate and specific tax consequences, hardships, the goal of self-support within a reasonable period, and any other equitable factor
The marital standard of living is a reference point, not an automatic guarantee that two post-separation households can reproduce the same lifestyle.
What Does the 10-Year Rule Actually Mean?
Family Code section 4336 creates a presumption that a marriage of at least 10 years—from the date of marriage to the date of separation—is of long duration for the purpose of retaining jurisdiction. A court may also find a shorter marriage to be of long duration in the right circumstances.
The statute does not promise lifetime support, fix an amount, or prevent later termination. It mainly addresses the court’s continuing ability to revisit support unless the parties agreed otherwise or the court terminated jurisdiction.
How Long Can Support Last?
California Courts explains that support is intended to last a reasonable period for the supported spouse to become self-supporting, with marriage length influencing the analysis. For a shorter marriage, courts commonly use approximately one-half the marriage length as a general reference point; longer marriages do not carry the same presumed endpoint.
Actual duration can depend on the judgment, agreement, section 4320 evidence, earning capacity, health, childcare responsibilities, progress toward self-support, and whether the court reserves jurisdiction.
Can a Spousal-Support Order Be Modified?
A modifiable order can often be changed after a significant change in circumstances, such as job loss, retirement, a substantial income shift, disability, changed need, or increased earning capacity. But the existing judgment may contain a nonmodifiable agreement, step-down schedule, termination date, or other language that changes the analysis.
Informal payment changes do not replace the court order. A person seeking modification should act promptly and obtain advice about the existing terms before assuming that support has changed.
When Does Support End?
Under Family Code section 4337, unless the parties agreed otherwise in writing, the obligation terminates when either party dies or the supported party remarries. Support may also end on a date stated in the judgment or agreement, or through a later court order.
