Child Support in Alpine County, California

Alpine County is California's least populous county. It has fewer than 1,200 residents and no incorporated cities. A child support case here moves through a small, shared system, not a large county office. The Superior Court of California, County of Alpine is at 14777 CA-89 in Markleeville, 96120, phone (530) 694-2113. That one courthouse handles every family law filing in the county.

Child support enforcement does not go through a separate Alpine office. It goes through the Central Sierra Child Support Agency, a regional office for Alpine, Amador, Calaveras, and Tuolumne counties at 75A Diamond Valley Road in Markleeville. The agency you call for an Alpine case also answers calls from three nearby counties. Hold times and appointment openings may be longer than you expect from an office so close to home.

Family Code section 4055 sets the number statewide. The formula weighs what each parent brings home and how many overnights the child spends in each home. The formula does not change because you live in Alpine County. The local difference is which office handles your papers. Use the free guideline calculator at https://childsupport.ca.gov/guideline-calculator/ before you file, so you have a rough support number in mind. Then file a Request for Order (FL-300) with an Income and Expense Declaration (FL-150) yourself, or ask Central Sierra to open and enforce a case.

Alpine's court does not have a public e-filing portal or a records terminal at the courthouse. Paper filing at the window in Markleeville is the standard path. If you cannot afford the filing fee, ask the clerk for a Request to Waive Court Fees (FW-001).

How child support is calculated in California

California sets child support with a statewide uniform guideline (Family Code section 4055) that applies the same way in Alpine County as everywhere else. The formula is based mainly on two things:

1. Both parents' net disposable incomes.
2. The percentage of time the child spends with each parent (the timeshare).

The guideline amount is presumed to be correct, and courts use a calculator to run the numbers. Because the result depends on accurate income, the Income and Expense Declaration (Form FL-150) you file is what drives your number.

Where child support cases are handled in Alpine County

Child support in Alpine County is handled through the Superior Court of California, County of Alpine, and the county's Local Child Support Agency, which is part of the California Department of Child Support Services. There are two common paths:

1. Either parent files a Request for Order (Form FL-300) with an Income and Expense Declaration (Form FL-150) inside a divorce, parentage, or custody case.
2. The Local Child Support Agency opens a case to establish, collect, and enforce support, often at no cost to the parents.

Local notes for Alpine County

Alpine has no incorporated town other than Markleeville. There is no separate branch courthouse or self-help annex to pick from. Everything goes through the one building on CA-89. The self-help resource listed at https://www.alpine.courts.ca.gov/ can explain which form to bring. Staff there will not tell you how your specific case should come out.

Confirm the facilitator's current hours before you drive out. Small counties like this one often offer family law help on a limited weekly schedule, not daily drop-in hours. The court's site does not say if a commissioner or a judge hears support matters here, so ask the clerk when you check in for a hearing. If you are coordinating with a parent in Amador, Calaveras, or Tuolumne, remember that Central Sierra Child Support Agency covers your case too. One call can sometimes clear up a multi-county issue.
