Spousal Support in Oakland and Alameda County, California

Spousal support in Alameda County is requested through the Superior Court of California, County of Alameda. All family law filings, including requests for temporary spousal support, go to the Hayward Hall of Justice in Hayward. They do not go to the Oakland or Fremont courthouses. Alameda County has its own local guideline, often called the Alameda formula. It appears in Local Rule 5.70. The court uses it to estimate temporary spousal or partner support while a case is pending.

California law treats temporary support and long term support differently. Temporary support is requested while a divorce or separation case is still open. It is usually calculated with a formula, not with the broader factors used for a final order. Alameda's Local Rule 5.70 gives two versions of that formula. One is a percentage calculation for cases with no child support. The other is a more detailed calculation tied to the same income components used in the statewide child support guideline, Family Code sections 4055 through 4069, when child support is also being set.

A request for temporary spousal support is usually made with Form FL-300, Request for Order. It must be supported by a completed Form FL-150, Income and Expense Declaration, which lists each spouse's income and expenses. These are the same statewide Judicial Council forms used in every California county. What is specific to Alameda is the local formula the court uses and the rule that every filing goes to the Hayward Hall of Justice, no matter where you live in the county, including Oakland, Fremont, Hayward, Berkeley, or San Leandro.

Long term spousal support is decided at the end of a case, not while the case is pending. It is not set by a formula. Instead, California Family Code section 4320 lists the factors a judge must weigh. These include the length of the marriage, each spouse's earning capacity, age and health, and the standard of living during the marriage. That statute applies in Alameda County the same way it applies throughout California.

How spousal support works in California

California distinguishes between temporary spousal support, ordered while a case is pending, and long-term spousal support, ordered at judgment. For temporary support, many counties, including some large ones, have adopted a local guideline formula (commonly run through software like DissoMaster or XSpouse) that produces a presumptive number; other counties leave temporary support to the judge's discretion without a local formula.

Long-term spousal support, by contrast, has no formula anywhere in California. A judge weighs the factors in Family Code section 4320, including each spouse's earning capacity, the marital standard of living, the length of the marriage, and the supported spouse's ability to become self-supporting. Spousal support is requested with a Request for Order (Form FL-300) and an Income and Expense Declaration (Form FL-150), inside a divorce or legal separation case.

Local notes for Alameda County

Alameda County's Local Rule 5.70 formula uses the payor's and payee's net income. When there is no child support in the case, the formula is 40% of the payor's net income minus 50% of the payee's net income. When child support is also at issue, the rule uses a more detailed calculation based on the child support income components. Courts usually run this calculation through DissoMaster or a similar approved support calculation program instead of doing it by hand. Local Rule 5.61 also refers to a DissoMaster printout as part of the paperwork expected before a contested support hearing.

The court's Office of the Family Law Facilitator was established under Local Rule 5.10 and is based at the Hayward Hall of Justice. It helps self-represented spouses understand which forms to file and how to fill out Form FL-150. It can explain the general process for requesting temporary support, but staff cannot advise on the likely outcome of a specific case. Because all family law filings in Alameda County go to the same Hayward courthouse, no separate department elsewhere in the county hears spousal support motions.

Alameda County's Family Law Division offers e-filing for family law documents. E-filing became mandatory for attorneys in October 2023. It is still optional for people who represent themselves, who may file paperwork in person at the Hayward Hall of Justice if they prefer. Anyone who e-files must submit documents as searchable PDFs through a court-approved provider and follow the courtesy-copy rules for the assigned department.
