Personal injury lawyer in Sonoma County: courts, claims and agencies that matter after an injury

We handle personal injury cases from car crashes and falls to elder abuse and wrongful death. This page lists the Sonoma County offices those cases are most likely to involve, from the first report to the courtroom, each taken from the official source listed at the end. Our office city has its own page: personal injury help in Cotati.

How does an injury case move through Sonoma County, step by step?

1. The report. The CHP or a city police department takes the crash report; a store or landlord takes an incident report after a fall.
2. Medical care and records. Providers must send you copies of your records within 15 days of a written request (Health and Safety Code 123110).
3. Insurance claims. Claims open with the other side's insurer and, where it applies, your own.
4. A claim to a public entity, if one is involved. The County, a city, Caltrans or a district must receive a written claim within six months (Government Code 911.2).
5. Settlement talks. Once treatment is far enough along, the claim is presented with records and bills.
6. A lawsuit, if needed. Generally within two years of the injury (Code of Civil Procedure 335.1), in the Sonoma County Superior Court when the injury happened here.

Which offices handle an injury case in Sonoma County?

Where is an injury lawsuit filed in Sonoma County?

For an injury or a death, California law makes the superior court of the county where the injury happened, or where a defendant lives, a proper court (Code of Civil Procedure 395). For an injury in Sonoma County, that includes the Sonoma County Superior Court.

The court's Civil Clerk's Office and civil courtrooms 18 to 23 are in the Civil and Family Law Courthouse at 3055 Cleveland Avenue, Santa Rosa, which also houses the Civil Self-Help Center. The building is open Monday to Friday, 8:00 AM to 5:00 PM, and the Civil Clerk's phone line is answered from 8:00 AM to 3:30 PM. From Highway 101, the court directs visitors to the Guerneville Road and Steele Lane exit; the courthouse entrance is at the western end of the building, facing the parking lot.

The court moved several departments in July 2026. Over three weekends starting July 20, 2026, it opened a new courthouse, the Hall of Justice at 625 Administration Drive. Traffic and limited civil matters opened on its first floor, and the criminal, traffic, juvenile dependency, mental health and records clerk's offices moved there. Limited civil cases are generally those where the amount in dispute is $35,000 or less (Code of Civil Procedure 85). The court's announcement says civil and family law matters remain at 3055 Cleveland Avenue. Our guide on what to expect at Sonoma County Superior Court in a personal injury case walks through each step after filing.

Who takes the crash report?

The CHP Santa Rosa Area office serves the majority of Sonoma County; the Sonoma Valley east of Trinity Road is served by the CHP's Napa Area office. Inside a city, the city's own police may take the report instead. Our guide on how to get the crash report in Sonoma County lists the CHP and city records offices. The reports that are due, and when, are covered in what happens in the first 30 days after a car accident in Sonoma County.

After a hit-and-run, timing matters more. For your own uninsured motorist coverage to pay, the crash must be reported within 24 hours to the police of the city where it happened or, outside city limits, to the Sheriff or the CHP (Insurance Code 11580.2). Read what to do after a driver flees in Sonoma or Marin County.

How do I make an injury claim against the County of Sonoma?

Use the County's claim form, complete every required section, and attach what supports the claim, such as reports, receipts and photographs. Send it by U.S. mail or deliver it in person to the Clerk of the Board of Supervisors, 575 Administration Drive, Suite 100A, Santa Rosa. The Board forwards it to Sonoma County Risk Management for investigation and sends a letter with your claim number; status questions go to Risk Management at [email protected]. The County notes that you may seek the advice of an attorney at any time during the investigation.

For an injury, the claim is due within six months (Government Code 911.2). Cities, the State and special districts each take their own claims, so the first step is working out who owns the road, vehicle or property involved. Our guide on how to file an injury claim against a city, county or the State walks through each step. A separate guide covers crashes involving a county vehicle, a public bus or a dangerous road.

Do the cities handle reports and claims differently?

Yes. Each city takes its own claims, and police reports come from different offices: Windsor and the City of Sonoma contract with the Sheriff's Office for their police, while Santa Rosa, Petaluma, Rohnert Park, Healdsburg and Cotati have their own departments. Our city pages list the local offices:

• Santa Rosa, the county seat.
• Petaluma.
• Rohnert Park.
• Windsor.
• Healdsburg.
• The City of Sonoma.
• Cotati, where our office is.

Who investigates a death in Sonoma County?

The Sheriff's Office Coroner Bureau, at 3336 Chanate Road in Santa Rosa, investigates deaths in the county that meet the criteria in Government Code section 27491. Its detectives respond when a death is being investigated as a homicide, suicide or accident, and the Sheriff's Office says the county averages about 400 autopsies a year. For families, our guide on what happens after a fatal crash in Sonoma County explains how the coroner, the crash report and any criminal case fit together.

Where do we report abuse or neglect of an older adult?

Adult Protective Services, part of the County's Adult and Aging Division, accepts and investigates reports of suspected abuse or neglect of adults 60 and older and of adults 18 to 59 with disabilities. Reports go to its 24-hour line, (707) 565-5940, or (800) 667-0404; the Division's main number is (707) 565-5900, and its lobbies are open Monday to Friday, 8:00 AM to 5:00 PM. When the abuse happens in a nursing home or other long-term care facility, state law sends staff reports to the long-term care ombudsman, local law enforcement and the state licensing agency instead (Welfare and Institutions Code 15630).

For a resident of a nursing home or other long-term care facility, the Long-Term Care Ombudsman Program for Sonoma County is run through Senior Advocacy Services, 1129 Industrial Avenue, Suite 201, Petaluma, (707) 526-4108. Complaints about a licensed health facility go to the California Department of Public Health's Santa Rosa office, which covers Sonoma, Marin, Napa, Mendocino, Humboldt, Lake and Del Norte counties. Our elder abuse and neglect page explains when a civil claim is possible. Our list of legal resources for Northern California residents includes referral and legal aid services.

What changes the answer?

Where in the county it happened. Inside a city, the city police usually take the report and the city takes claims; outside city limits, the CHP takes crash reports and the County takes claims for County roads and property. In the Sonoma Valley east of Trinity Road, the CHP's Napa Area office serves the area.

Who owns the road, vehicle or building. A County road or vehicle means a claim to the Clerk of the Board within six months; a state highway means Caltrans or the Department of General Services (Government Code 911.2).

Whether a death occurred. The Coroner Bureau's work and any criminal case run alongside the family's claim, which follows the deadlines for a wrongful death claim.

Whether the injured person is an older or dependent adult. Reporting routes differ for care facilities and for abuse elsewhere (Welfare and Institutions Code 15630), and the Elder Abuse Act can add remedies.

The size of the case. A case for $35,000 or less is a limited civil case (Code of Civil Procedure 85), and the court opened its limited civil matters at the new Hall of Justice in July 2026.

What could this look like? An example

For example, imagine a Sebastopol resident riding home on a County road who is hit by a pickup, and the driver says the County's faded center line confused him. A CHP officer from the Santa Rosa Area office takes the report, because the road is outside city limits. Within six months, the rider presents a claim to the Clerk of the Board of Supervisors on Administration Drive, in case the road's condition played a part, and claims against the driver's insurer at the same time.

If the County rejects the claim in writing, any lawsuit against it is due within six months of the notice; the claim against the driver generally has two years. A lawsuit for both would be filed at the Civil and Family Law Courthouse on Cleveland Avenue. This example is made up to show how the county offices fit together; it predicts nothing about a real case.

What mistakes do people make in Sonoma County cases?

• Asking the CHP for a report a city police department took, or the reverse.
• Missing the six-month claim because a County road or vehicle was not obvious at first.
• Sending a claim against a city to the County, or the reverse.
• Going to the Hall of Justice for an unlimited civil case that stays on Cleveland Avenue.
• Reporting abuse in a nursing home only to Adult Protective Services instead of the ombudsman and the state licensing office.

What should I do this week?

1. Find out which agency took the report, and request it.
2. Decide whether the County, a city or the State could be involved, and mark the six-month date.
3. Request your medical records in writing.
4. Keep every insurance letter and claim number.
5. Call us to talk through the deadlines that apply.
