Spousal Support in Mono County, California

Mono County spousal support cases are filed through the Superior Court of California, County of Mono. The court has two branch locations, not one central courthouse: the North County Branch at 278 Main Street in Bridgeport, the county seat, and the South County Branch at 100 Thompsons Way in Mammoth Lakes, the county's largest and best known community. The branch that handles your spousal support filing can depend on where the case was originally filed, so confirm the correct location before submitting paperwork.

To request spousal support while a case is pending, a party generally files Form FL-300, Request for Order, along 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, with a response due at least 9 court days beforehand.

Mono County uses the same statewide certified guideline calculation approach as every other California court to set temporary spousal support. DissoMaster was discontinued as of April 1, 2025, so the court now relies on XSpouse or a comparable Judicial Council-certified program to calculate the temporary amount from each party's income and other required data.

For long-term support, Mono County judges apply the factors in Family Code section 4320 rather than a formula. They weigh the length of the marriage, each spouse's earning capacity, age, health, and the standard of living during the marriage.

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 Mono County

Mono County's two court branches have different clerk's office hours. The Mammoth Lakes South County Branch is open Monday through Thursday from 8:30 a.m. to 4:00 p.m. and Friday from 8:30 a.m. to noon, phone (760) 924-5444. The Bridgeport North County Branch keeps much more limited hours, with the clerk's office open only Tuesdays from 8:30 a.m. to noon and 1:15 p.m. to 4:00 p.m., phone (760) 932-5239. Confirm current hours before planning a visit to either location.

Facilitator-style help with forms is offered in part through the LawHelp Interactive Form Assembly Program rather than a single dedicated in-person facilitator office. Ask either branch's clerk about current options for spousal support paperwork assistance.

No dedicated e-filing portal for family law was confirmed on the court's public pages. Plan to file spousal support paperwork in person at the appropriate branch, and keep in mind the limited Tuesday-only hours in Bridgeport.

Mono County residents who cannot afford the filing fee can ask for a waiver on Form FW-001, the same statewide form used across California. Family Code section 4325 also applies: a spouse convicted of a qualifying domestic violence offense against the other spouse within the five years before filing faces a rebuttable presumption against receiving spousal support, on top of the general 4320 factors.
