Spousal Support in Sierra County, California
A plain-language guide to spousal support in Sierra County, from how temporary and long-term support are calculated to the forms you file at the Superior Court of California, County of Sierra and how to prepare your paperwork without hiring an attorney.
Spousal support cases in Sierra County are filed with the Superior Court of California, County of Sierra, at 100 Courthouse Square in Downieville. Downieville is a historic gold rush town and the county seat of one of California's least populated counties. This small court handles all family law matters for people spread across steep, forested areas, not a large urban caseload.
Sierra County does not have its own dedicated Family Law Facilitator. It shares that service with neighboring Nevada County. The facilitator holds hours in Nevada City, Truckee, Downieville, and Loyalton at different times each month. If you need help with spousal support paperwork, call ahead for the current schedule.
To ask for spousal support while a case is pending, a party usually files Form FL-300, Request for Order, with a completed FL-150 Income and Expense Declaration. California Rule of Court 5.92 requires at least 16 court days notice of the hearing. A response is due at least 9 court days beforehand.
Sierra County calculates temporary spousal support using the same statewide method as every California court. Family Code section 4320 controls long-term support decisions, as it does across California. DissoMaster was discontinued as of April 1, 2025, and XSpouse or a comparable Judicial Council-certified program is now used to run temporary support figures.

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.
