Formula-Based

This formula applies ONLY to temporary support. Long-term/permanent support is determined by the court's analysis of all 14 factors in Family Code Section 4320 -- the guideline formula cannot be used for long-term support.

Types of Alimony in California

Temporary (Pendente Lite) Support

Awarded during the divorce proceedings to maintain the status quo. Calculated using county-specific guideline software, most commonly the Santa Clara Guideline formula: 40% of the higher earner's net income minus 50% of the lower earner's net income. Ends when the divorce is finalized and a long-term order is made.

Long-term (Permanent) Support

Ordered as part of the final judgment based on Family Code Section 4320 factors. For marriages of long duration (10+ years per FC 4336), the court retains jurisdiction indefinitely and shall not set a termination date. For short marriages (under 10 years), support is typically ordered for half the length of the marriage.

Rehabilitative Support

A form of long-term support aimed at enabling the supported party to become self-supporting through education, training, or retraining. Family Code Section 4320(l) establishes the goal that the supported party shall be self-supporting within a reasonable period of time.

Reimbursement Support

Available when one spouse supported the other through education or training with the expectation of shared benefit. Community contributions to education or training may be reimbursed under Family Code Section 2641.
