Spousal Support in Fairfield and Solano County, California
A plain-language guide to spousal support in Solano County, from how temporary and long-term support are calculated to the forms you file at the Superior Court of California, County of Solano and how to prepare your paperwork without hiring an attorney.
If you ask for spousal support in Solano County, your case is heard by the Superior Court of California, County of Solano, at the Hall of Justice in Fairfield. Spousal support is also called alimony. You can ask for it in an open divorce or legal separation case. You can also ask later with a Request for Order (FL-300) if circumstances change after judgment.
California treats spousal support in two stages. Solano County has a local rule for temporary support. Temporary spousal support applies while a divorce or legal separation is pending. Local Rule 5.30 says the court has adopted the Santa Clara guideline to calculate it. That guideline uses each spouse's net income, so both sides need accurate income information.
Long term spousal support is different. It is decided at the end of a case, or later when support is modified after a long marriage. It is not calculated by a formula anywhere in California, including Solano County. The judge weighs the factors in Family Code section 4320. These include each spouse's earning capacity, the length of the marriage, age and health, and the standard of living during the marriage.
At either stage, the court uses statewide Judicial Council forms. One key form is the Income and Expense Declaration (FL-150). Both spouses complete it so the court has income and expense numbers. Solano County's Family Law Facilitator's Office, at the Hall of Justice, helps self-represented people with forms and procedure questions.

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.
