Orange County probate notes, filing, and hearings

Last verified: July 14, 2026

The short answer: Orange County probate cases are filed with the Superior Court's Probate Division at the Costa Mesa Justice Complex using Petition for Probate form DE-111. The filing fee is $435. Attorneys must e-file most probate papers; a self-represented petitioner may file on paper or e-file voluntarily. Before the hearing, check the court's online probate notes and sign up for a text or email alert when a new note appears in the case.

Before you file anything, check whether you need probate at all. The simplified paths at the bottom of this page skip the process entirely for many families.

Where do you file probate in Orange County?

Probate is heard in the county where the person lived at their death. For Orange County, that means one place (occourts.org):

Courthouse Address Phone
Costa Mesa Justice Complex 3390 Harbor Blvd., Costa Mesa, CA 92626 (657) 622-8452

The Probate/Mental Health clerk's office and the probate courtrooms are all at the Costa Mesa Justice Complex (occourts.org). Do not take probate papers to the Central Justice Center in Santa Ana or any other Orange County courthouse.

How much does it cost to file probate in Orange County?

Item Fee Source
First-filed Petition for Probate (letters testamentary or letters of administration) $435 Gov. Code § 70650(a), statewide civil fee schedule effective Jan. 1, 2026
Orange County surcharge None The statewide schedule adds local courthouse-construction surcharges only in Riverside, San Bernardino, and San Francisco counties

If you e-file, the e-filing service provider charges its own convenience fee on top of the $435.

The petition fee is only one part of the total cost. See the California probate-fee guide for statutory attorney and executor compensation, publication, appraisal, bond, and other expenses.

How do you file the petition?

Orange County was an early mover on electronic filing. Since September 3, 2013, "all papers filed by attorneys in probate proceedings, other than the original documents specified below, must be filed electronically." Self-represented parties "are exempt from the mandatory electronic filing requirement, but are strongly encouraged to participate voluntarily" (occourts.org).

E-filing goes through one of the court's approved electronic filing service providers: DDS Legal, E-Filings of America, First Legal, LegalConnect, Nationwide Legal, One Legal, or TurboCourt (occourts.org).

Some documents must still be filed on paper even by attorneys. The most important one for an executor: original wills and codicils cannot be e-filed. Bring or mail the original to the clerk at Costa Mesa.

How long until the first hearing?

State law says the hearing on the petition "shall be set for a day not less than 15 nor more than 30 days after the petition is filed," or 30 to 45 days out if you request it (Prob. Code § 8003). The department's calendar controls the actual setting; use the filed hearing notice rather than an unofficial estimate.

Use the gap well. You must publish notice of the hearing in a newspaper and mail notice to heirs before the hearing, and you should watch your probate notes as the date approaches.

For the statewide stages after appointment, see how long California probate takes.

What are probate notes and how do you clear them?

A court probate examiner reviews your petition before the hearing and posts probate notes listing anything missing or defective (occourts.org).

What local quirks should an executor know?

Can you skip probate entirely?

Formal probate is the expensive road. Two shortcuts cover many Orange County families, using the thresholds on Judicial Council form DE-300 (rev. April 2025) for deaths on or after April 1, 2025:

If Then
The probate estate is $208,850 or less No probate. After 40 days, collect assets with a small-estate affidavit under Probate Code §§ 13100 to 13101
The main asset is the primary residence, worth $750,000 or less A simplified court petition (form DE-310) instead of full probate

For what counts toward those numbers and what skips probate automatically, see our California executor checklist.
