Temporary support in California is calculated using a guideline formula during the divorce proceedings to maintain the financial status quo.
Temporary spousal support uses county-specific guideline formulas. The most common is the Santa Clara (Guideline) formula: 40% of the higher earner’s net income minus 50% of the lower earner’s net income. Permanent (long-term) support has no formula and is determined by a 14-factor analysis under FC §4320.
Permanent (long-term) support in California is determined by a statutory multi-factor analysis under FC §4320. The court weighs the following factors to arrive at a fair support amount and duration. Unlike the temporary formula, there is no mathematical calculation for permanent support — it is a discretionary determination by the judge based on the totality of the circumstances.
The types of spousal support available in California include: Temporary (pendente lite), Rehabilitative, Permanent (long-term). The type ordered depends on the length of the marriage, each spouse's financial situation, and the supported spouse's ability to become self-supporting.
Primary statute: FC §4320
The court considers these 14 statutory factors when determining the amount and duration of spousal support:
The extent to which earning capacity of each party is sufficient to maintain the marital standard of living
The extent to which the supported party contributed to the attainment of education, training, career, or license of the supporting party
The ability of the supporting party to pay, considering earning capacity, earned and unearned income, assets, and standard of living
The needs of each party based on the marital standard of living
The obligations and assets of each party, including separate property
The duration of the marriage
The ability of the supported party to engage in gainful employment without unduly interfering with the children’s interests
The age and health of the parties
All documented evidence of any history of domestic violence
The immediate and specific tax consequences to each party
The balance of hardships to each party
The goal that the supported party shall be self-supporting within a reasonable period of time
The criminal conviction of an abusive spouse (FC §4325)
Any other factors the court determines are just and equitable
For marriages under 10 years, support duration is generally half the length of the marriage. For marriages of 10 years or longer (FC §4336 "marriage of long duration"), the court retains jurisdiction indefinitely — there is no automatic termination date.
Duration is one of the most heavily litigated aspects of spousal support. The length of the marriage is the single most important factor in most cases, but the court also considers the supported spouse's age, health, job skills, and the time needed to acquire education or training for appropriate employment.
Gavron warning: courts must advise the supported spouse of the expectation to become self-supporting within a reasonable period (FC §4330).
The "marital standard of living" is the benchmark for both temporary and permanent support — a concept unique in its statutory emphasis in California.
