Quick Answer: A Petition for Probate (Judicial Council Form DE-111) is the document that formally opens a California probate case. It asks the court to admit the decedent’s will (if there is one), appoint a personal representative (executor or administrator), and issue Letters authorizing that person to act. Filing it starts a process that includes mailed and published notice to heirs and beneficiaries, a court hearing, and, once granted, the Letters that let the representative actually manage the estate.
What the Petition for Probate Actually Does
Form DE-111 is the single document that opens most California probate cases (Probate Code Sections 8002 and 10450). It tells the court three things: whether there’s a will to admit, who should be appointed to run the estate, and whether that person needs full or limited authority under the Independent Administration of Estates Act. Filing it is what triggers a case number, a hearing date, and everything else that follows.
Who Can File It
If the decedent left a will naming an executor, that person has priority to file. If there’s no will, or the named executor can’t or won’t serve, any “interested person” (a spouse, adult child, other heir, or even a creditor in some cases) can petition to be appointed administrator. The form itself asks the petitioner to state their relationship to the decedent and their priority to serve, since California law ranks who gets appointed when more than one person wants the job.
What Has to Be Attached and Disclosed
Beyond the appointment request, DE-111 requires a fairly detailed family tree: surviving spouse or domestic partner, children, and, if there’s no immediate family, more distant heirs down to next of kin. It also asks for the estate’s estimated value (real property, personal property, and annual income from each), since that figure determines whether a bond is required and how much it needs to be under Probate Code Section 8482. If the original will can’t be located, there’s a separate box for petitioning on a lost will instead.
Notice: Mailed and Published
Once the petition is filed, California law requires two separate kinds of notice before the hearing can happen. The Notice of Petition to Administer Estate (Form DE-121) has to be mailed to everyone named in the will, all legal heirs, and certain other interested parties at least 15 days before the hearing date, under Probate Code Section 8110. It also has to be published three times in a newspaper of general circulation in the city where the decedent lived, with the first publication at least 15 days before the hearing and at least five days between the first and last publication dates, under Probate Code Section 8120. Both the mailing and the publication have to be proven to the court with a filed proof of service and proof of publication before a judge will act on the petition.

The Filing Fee and What Happens at the Hearing
Filing a Petition for Probate costs $435 statewide (Government Code Section 70650), the same fee that applies to opening any decedent’s estate case in California. At the hearing itself, if no one objects and the paperwork is in order, the judge typically approves the petition without the petitioner needing to say much beyond confirming the facts under oath. The court then issues Letters Testamentary (if there’s a will and named executor) or Letters of Administration (if not), the document that actually gives the representative legal authority to act. For the full mechanics of that next step, see our guide to California Letters of Administration.
Petition for Probate vs. Later Filings
It’s worth separating this petition from the paperwork that comes after appointment. Once Letters are issued, the representative still has to file an Inventory and Appraisal, handle creditor claims, and eventually petition again for final distribution. The DE-111 petition only covers the opening step: getting someone legally appointed to run the estate in the first place.
Need Funds While Probate Is Still Open?
Even after a petition is granted and Letters are issued, a California probate case commonly takes 9 to 18 months to close, and heirs typically can’t touch their inheritance until then. ProbateLend offers a probate advance that gives qualifying heirs a portion of their expected inheritance now, without waiting for the estate to formally close. There’s no credit check and no monthly payments; repayment comes out of the estate at final distribution.
Frequently Asked Questions
Do I need a lawyer to file a Petition for Probate?
Not legally, but the form is dense and a rejected or incomplete petition can delay the hearing by weeks. Many California courts have self-help centers that review petitions for completeness, though they can’t give legal advice on how to fill out contested items.
What if the named executor doesn’t want to serve?
They can decline, and the next person entitled to Letters under the priority order can petition instead, or the will’s alternate executor (if one is named) can step in. The DE-111 form has a specific box for stating why the originally named executor won’t act.
Can more than one person file the petition together?
Yes, co-petitioners are allowed and all of them must sign the form, though the petition only needs to be verified (sworn to) by one of them.
What happens if someone contests the petition?
If a valid objection is filed before the hearing, the judge can’t simply grant the petition on the papers. The matter moves toward a contested hearing where both sides present evidence, which extends the timeline well beyond the standard uncontested schedule.
Is the $435 filing fee the only cost at this stage?
It’s the only mandatory court fee to open the case, but petitioners also pay for the required newspaper publication (varies by publication) and, if a bond is required, the bond premium itself.
