Mono County Probate Filing Fees

California court fees are largely set statewide. Here's what to budget for a Mono County probate:

Item	Typical cost	Notes
Petition for Probate (DE-111)	$435	Opens the estate; set by Gov. Code §70650. Plus applicable surcharges.
Petition for Final Distribution	$435	Filed near the end to close the estate and distribute assets.
Certified copy of Letters	~$25–$40 each	Order several — banks and institutions require recent certified copies.
Newspaper publication	~$200–$500	Paid to the newspaper, not the court (Probate Code §8121).
Probate referee	0.1% of non-cash assets	Min $75 / max $10,000 (Probate Code §8961); appraises non-cash assets.

Can't afford the fees? California lets you request a fee waiver (form FW-001) if you meet the income guidelines. And remember: the court fees above are separate from — and usually much smaller than — California's statutory attorney and executor fees, which are a percentage of the estate's gross value. Estimate those with our probate cost calculator.

Required Probate Forms

California uses statewide Judicial Council forms. These are the core ones to open a case — all free to download:

DE-111

Petition for Probate. Opens the estate and requests appointment of the personal representative.

DE-147

Duties and Liabilities of Personal Representative. Signed and filed with the petition.

DE-121

Notice of Petition to Administer Estate. Published in a newspaper and mailed to heirs.

DE-120

Notice of Hearing. Mailed to heirs and beneficiaries at least 15 days before the hearing.

DE-140

Order for Probate and DE-150 Letters — the appointment order and your Letters (your authority to act).

Download official forms free from the California Courts Judicial Council forms site — never pay a third party for them. See our full probate documents checklist for what each stage requires.

E-Filing, Records & Publication

Two practical things first-time filers ask about: how to file electronically, and the newspaper publication rule.

E-filing. Electronic filing for probate is generally available in California through approved e-filing service providers, though requirements vary by court and some smaller courts still accept paper filings. Confirm the current process for Mono County on the court's website before filing. It's generally done through an approved e-filing service provider. Confirm current requirements on the court's website, and note that the original will usually must still be lodged in paper form.

Publication (the step people miss). California Probate Code §8121 requires publishing a Notice of Petition to Administer Estate (form DE-121) in a newspaper of general circulation in Mono County (ask the court clerk which local papers are court-adjudicated to publish legal notices), once a week for three consecutive weeks, before the hearing. The newspaper must be one of general circulation qualified to publish legal notices. This is separate from mailing notice to heirs, and it typically costs $200–$500. Ask the clerk or an attorney which local papers are court-adjudicated for Mono County.

Do You Even Need Full Probate?

Not every Mono County estate requires full formal probate. California has simplified paths that skip most of it:

If the estate's qualifying personal property is under the small-estate threshold, heirs can often use a small estate affidavit (Probate Code §13100) instead of opening probate — no court case required. And a real-property petition can transfer a home under a separate value threshold with a streamlined court process. These thresholds are indexed and change periodically, so check the current figures with our small estate checker rather than relying on a fixed number. A surviving spouse may also use a Spousal Property Petition (§13650) to confirm ownership without full probate.

Not sure which path fits? The estate complexity quiz gives you a quick read, and the California probate guide walks through the full process.
