Los Angeles County Probate Courts
Where LA County probate cases are filed and heard, with official court links
Probate cases for the Superior Court of California, County of Los Angeles are heard at the Stanley Mosk Courthouse in downtown Los Angeles. The Antelope Valley Courthouse in Lancaster still accepts probate filings, but since February 2, 2026 its probate hearings have been held through Stanley Mosk. The details are below, with links to the court’s own pages. Check the court’s site before you file or appear, since assignments change.

3. Always confirm the department
- Use the department and hearing date on the Notice of Hearing or on counsel’s notice. Do not rely on a general list, including this one.
- Check Probate Notes before the hearing. The court generally posts them about two weeks ahead, and items under “Matters to Clear” must be resolved before the hearing.
- Court filings should show the assigned judicial officer and department on the first page, as the court’s notices instruct.
- Older Los Angeles probate case numbers may carry district prefixes. Do not assume a courthouse hears probate today just because an old case number points to it. Use the court’s current notices.
- If anything here conflicts with lacourt.org or lacourt.ca.gov, the court’s site controls.
Probate referees in Los Angeles County
The State Controller appoints probate referees, who appraise estate assets for the inventory. The Controller’s probate referee contact list has separate Los Angeles County entries (Los Angeles-Central and Los Angeles-North). Bill Gross is not a Probate Referee and does not perform probate appraisals.
Where Bill fits in
Bill Gross handles court-confirmation sales of probate real estate at the Stanley Mosk Courthouse, including the overbid process at the confirmation hearing, and IAEA sales that do not need a hearing. He is a licensed real estate broker, not an attorney. Your estate attorney handles filings, notices, and appearances. See how a court-confirmed sale works, or schedule a consultation about a property.
About this site: Bill Gross is a licensed California real estate broker (DRE #01022275). He is not an attorney and not a Probate Referee, and nothing here is legal advice. Court links go to official government websites, which control if anything here differs.
