How probate works in Mariposa County

Last verified: July 20, 2026

The short answer: Mariposa has one courthouse, at 5088 Bullion Street, Mariposa, CA 95338. The Civil Division handles non-guardianship probate and can be reached at (209) 966-6599; general court questions go to (209) 966-2005. Offices are open 8:00 a.m.–3:00 p.m. The court does not publish a probate e-filing service, examiner-note system, or standing probate tentative-ruling process, so use paper filing and confirm case-specific review with the Civil Division.

Mariposa County probate at a glance

Filing and the original will

The court's Civil Division accepts the probate petition at the historic courthouse. Because no official probate e-filing workflow is published, do not send a petition through an unrelated portal or by email. Use the counter, mail, or another method the clerk expressly authorizes.

Preserve the original will exactly as found. Probate Code section 8200 generally requires its custodian to deliver it within 30 days after learning of the death. Include the case name or petition materials as the clerk directs so the will is associated with the correct file.

Hearing review and remote appearance

The court posts a weekly calendar and courtroom connection information. Most civil and probate hearings use the Upper Courtroom, but the individual notice controls. Zoom access is for parties on calendar and attorneys; it is not a general public viewing link or automatic permission to disregard an in-person order.

No probate examiner notes or routine tentative rulings are published. Check the accepted notice, weekly calendar, and electronic record, then call the Civil Division about defects or appearance requirements.

Local forms, fees, and practical quirks

No generally mandatory Mariposa decedent-estate local form or county probate surcharge was identified. The court publishes a local probate referee contact—a useful county-specific resource for Inventory and Appraisal work after appointment. The $435 statewide fee applies, with copy, certification, publication, and referee costs arising as the case proceeds.

The court's current local-rules page does not publish a separate decedent-estate chapter or county opening checklist. Statewide Probate Code and Judicial Council rules therefore supply the baseline, subject to any case-specific clerk or judicial instruction.

Mariposa County's practical checklist:

• File and appear at the single Bullion Street courthouse.
• Plan around the 3:00 p.m. office close.
• Use paper unless the clerk confirms another authorized filing channel.
• Lodge the original will within the statutory period.
• Check the weekly calendar and confirm whether the Upper Courtroom Zoom link applies.
• Contact the Civil Division because no public examiner-note or tentative system was identified.

Court procedures change; verify filing and hearing details with Mariposa County Superior Court before acting.
