How to Complete California Probate Form De-111

Filing a petition for probate in California starts with one form: DE-111, officially called the Petition for Probate. If you've been named as an executor in someone's will or you're a surviving family member trying to settle an estate you'll need to fill out this form correctly before a probate judge can appoint you as the personal representative. Mistakes on DE-111 can delay the entire process by weeks or even months. Getting it right the first time saves you time, money, and frustration.

What is Form DE-111 and why does the California probate court require it?

Form DE-111 is the official petition filed with the California Superior Court to open a probate case. It tells the court who has died, what assets they left behind, who should be appointed to manage the estate, and who stands to inherit. Without this form, the court has no basis to issue Letters Testamentary or Letters of Administration, which are the legal documents that give the executor authority to act on behalf of the estate.

You can find the official DE-111 form on the California Courts website. It's a fillable PDF, and most California counties accept both electronic and paper filings.

When should you file the DE-111 petition for probate?

You should file DE-111 as soon as reasonably possible after someone dies. California law doesn't set a strict deadline, but waiting too long can create problems creditor claims may pile up, assets may lose value, and heirs may become impatient or contest the process. Understanding executor responsibilities and deadlines helps you stay on track once the court appoints you.

You file DE-111 in the superior court of the county where the decedent lived at the time of death. If the decedent owned property in multiple counties, you'll typically file in the county of their primary residence.

Who is eligible to file Form DE-111?

California law establishes a priority order for who can petition the court:

Named executor in the decedent's will
Surviving spouse or domestic partner
Adult children or other heirs
Creditors (in limited circumstances)
Any other interested person

If you're a surviving spouse deciding between different petition types, you may want to compare your options. Some cases call for a spousal property petition instead of a standard probate petition, and understanding the differences between California probate court petition types can help you choose the right path.

How do you fill out the top section of Form DE-111?

The first section asks for basic case information. Here's what goes where:

Attorney information (Item 1): If you're representing yourself, check the box for "In Pro Per." If you have a lawyer, enter their name, State Bar number, address, phone, and email.

Party information (Item 2): Enter your full legal name. You're listed as the petitioner. Then list the name of the decedent.

Court location (Item 3): Fill in the county and the courthouse address. Each county has its own probate division, so verify the correct filing location before submitting.

What goes in the decedent information section (Items 4–7)?

This section identifies the person who died and provides key legal facts.

Item 4 – Decedent's name and death details: Enter the decedent's full legal name (as it appears on the death certificate), the date of death, the city and county of death, and the state. Double-check these details against the death certificate. A mismatch even a small one can cause the court to reject the filing.

Item 5 – Will information: Indicate whether the decedent left a will. If yes, check the appropriate box and specify whether the will has been lodged with the court. You'll need to attach a copy of the will to the petition.

Item 6 – Type of probate: Check whether you're requesting independent administration (under the Independent Administration of Estates Act) or supervised administration. Most petitions request independent administration because it gives the executor more flexibility and reduces court oversight. If the will specifically grants independent administration authority, this is usually straightforward.

Item 7 – Bond: Indicate whether a bond is required. If the will waives bond, check that box. If there's no will or the will doesn't address bond, the court may require one unless you can show it's unnecessary.

How do you list the estate assets (Items 8–9)?

This is one of the most error-prone sections of the form.

Item 8 – Probate estate description: You need to list the assets that will go through probate. This includes real property, bank accounts, vehicles, personal property, and investments held solely in the decedent's name. For real property, include the street address and a general description. For financial accounts, list the institution and approximate value.

You do not need exact appraisals at this stage reasonable estimates are acceptable for the petition. The formal appraisal happens later, after the court appoints you.

Item 9 – Estimated value: Enter the estimated gross value of the probate estate. California requires probate if the estate's gross value exceeds $184,500 (as of 2024). If the estate falls below this threshold, you may be able to use simpler alternatives like a small estate affidavit instead of filing DE-111.

Keep in mind that non-probate assets like property held in a living trust, jointly owned accounts, or assets with named beneficiaries (like life insurance or retirement accounts) do not go on this form. Only assets that pass through the will or intestate succession belong here.

How do you complete the heirs and beneficiaries section (Items 10–12)?

This section identifies everyone with a legal interest in the estate.

Item 10 – Will beneficiaries: If there's a will, list every beneficiary named in it, their relationship to the decedent, and their share or interest under the will.

Item 11 – Heirs at law: Even if there's a will, you must list the decedent's heirs at law the people who would inherit under California intestate succession law. This typically includes the surviving spouse, children, parents, and siblings. List each person's name, relationship, age (if a minor), and address.

Item 12 – Additional persons to be notified: Include any other interested parties who need notice of the probate proceedings, such as the decedent's registered domestic partner, stepchildren, or anyone named as a beneficiary in a prior will.

Common mistake: Failing to list all required heirs. Even if someone is estranged or unlikely to contest, they must be listed. Omitting an heir can lead to objections, delays, or even a court order to restart the process.

What do you request in the petition (Items 13–15)?

Item 13 – Personal representative appointment: State who you're asking the court to appoint and in what capacity executor under the will or administrator if there's no will.

Item 14 – Powers requested: If you're requesting independent administration, specify whether you want full authority or limited authority under the Independent Administration of Estates Act (Probate Code §10400 et seq.). Full authority lets you sell real estate and take other actions without prior court approval. Limited authority requires court approval for certain transactions, like selling real property.

Item 15 – Special requests: This includes requests to waive bond, confirm the will, or any other relief you're asking the court to grant.

What signatures and attachments do you need?

The petitioner must sign and date the form under penalty of perjury. Your signature certifies that everything in the petition is true and correct to the best of your knowledge.

Required attachments typically include:

Original will (if one exists)
Certified copy of the death certificate
Any codicils to the will
Proof that you mailed Notice of Petition to Administer Estate (Form DE-121) to all interested parties at least 15 days before the hearing
Proof of publication in a local newspaper (if required by your county)

What are the most common mistakes people make on Form DE-111?

After seeing hundreds of probate petitions filed by self-represented litigants, these are the errors that come up most often:

Listing incomplete asset information. Vague descriptions like "various bank accounts" without naming the institutions will cause the court to reject the petition or demand amended filings.
Forgetting to list all heirs. You must include everyone in the line of intestate succession, even if the will cuts them out.
Wrong estimated values. Underestimating estate value can affect filing fees and later cause problems with the court. Overestimating can unnecessarily trigger higher costs.
Missing or incorrect notice requirements. California requires formal notice to all interested parties before the hearing. If you skip this step or send notice late, the court will continue the hearing.
Not checking the right boxes for independent vs. supervised administration. This affects your authority as executor and how much court oversight you'll have going forward.
Filing in the wrong county. The petition must be filed in the county of the decedent's legal residence, not where you live or where some of the assets are located.

What happens after you file Form DE-111?

Once you file the petition, the court assigns a hearing date usually 4 to 8 weeks out, depending on the county's backlog. Before the hearing, you must:

Mail Notice of Petition to Administer Estate (Form DE-121) to all interested parties at least 15 calendar days before the hearing date.
Publish the notice in a newspaper of general circulation in the decedent's county of residence, once a week for three consecutive weeks, with the last publication at least 15 days before the hearing.
File proof of service (Form DE-130) and proof of publication with the court before the hearing.

At the hearing, the judge reviews the petition. If no one objects and everything is in order, the court issues an Order for Probate and appoints the personal representative. The court then issues Letters Testamentary or Letters of Administration. Walking through the probate hearing process before your court date helps you know what to expect.

After appointment, the real work of administering the estate begins collecting assets, paying debts, filing tax returns, and distributing property to beneficiaries. There are specific executor responsibilities and deadlines you must follow throughout this process.

Should you hire a lawyer or fill out DE-111 yourself?

You can absolutely file DE-111 as a self-represented litigant. Many people do, especially for straightforward estates with a clear will, few assets, and cooperative beneficiaries. California courts provide self-help resources, and most probate clerks can answer basic procedural questions.

However, consider hiring a probate attorney if:

The estate involves disputes among heirs or potential will contests
There are complex assets like businesses, out-of-state property, or significant debts
There's no will (intestate) and the family structure is complicated
You're unsure about your duties and want professional guidance

Probate attorney fees in California are set by statute (Probate Code §10810) based on the estate's value typically 4% of the first $100,000, 3% of the next $100,000, and decreasing percentages for larger estates. These fees come from the estate, not your personal funds.
