DE-111 Petition for Probate: Line-by-Line California Guide

If you are filing your first California probate, the DE-111 Petition for Probate is where most of the anxiety comes from. Not because the law is unclear, but because the form feels rigid and unforgiving. A missed box, an inconsistent name, or an unsupported assumption about bond can easily result in a rejection or continuance.

This guide is written for attorneys who already know how to practice law but have not yet filed a probate petition. It walks through the DE-111 form line by line, explains what the court is actually looking for, and points out the mistakes that most commonly slow cases down.

Think of this as a desk reference you can keep open while completing the form, not a high-level overview.

What Is the DE-111 Form and When Is It Used?

Judicial Council Form DE-111 is the document that formally opens a probate estate in California. It asks the Superior Court to do three things:

• Recognize that a probate estate exists
• Determine who has priority to serve
• Appoint a personal representative

If you are initiating a full probate administration, you will almost always file a DE-111. It applies whether the decedent died with a will or without one.

Everything that follows in the case—Letters, inventories, authority to act—rests on the accuracy of this petition.

When You Do Not Use DE-111

You generally do not file a DE-111 for:

• Small estate affidavits
• Pure trust administrations
• Standalone spousal property petitions
• Heggstad petitions without a probate estate

Once you determine that a full probate is required, DE-111 is the starting point.

Before You Start: What You Need on Hand

Do not open the form until you have the following information. Most mistakes happen when attorneys try to fill gaps on the fly.

Documents

• Certified death certificate
• Original will and any codicils
• Trust documents (if referenced)

Information

• Decedent's full legal name and any aliases
• Date and place of death
• Residence at time of death
• Approximate gross value of probate assets
• Names and addresses of heirs and beneficiaries

If you are missing any of this, pause and gather it first. Fixing a bad filing later always takes longer.

Line-by-Line Walkthrough of DE-111

Caption

Enter your firm name, address, phone number, and State Bar number. Make sure this matches your signature block exactly.

List the correct county for venue. This is usually the county where the decedent was domiciled at death, not where they owned property unless domicile is unclear.

Items 1–2: Decedent Information

Use the decedent's full legal name exactly as it appears on the death certificate. If assets are titled under alternate names, list those as aliases.

For place of death, use the city and state. Do not list the hospital name unless it is also the city.

Items 3–4: Jurisdiction and Venue

This section establishes why the court has authority. Check the box that applies and make sure it is factually accurate. Courts review this more closely than many attorneys expect.

Items 5–6: Will and Codicils

Indicate whether the decedent died testate or intestate. If a will exists, attach the original. Copies are not sufficient without a supporting petition.

List all codicils with their execution dates. Inconsistent dates between the petition and the will are a common cause of continuances.

Items 7–9: Personal Representative

Identify the person you are asking the court to appoint. Be precise about their role: executor if named in the will, administrator if not.

Provide full legal name, address, and relationship to the decedent. Partial information here creates notice problems later.

Item 10: Priority for Appointment

This is where many first-time filers stumble. You must explain why this petitioner has priority under California law. Simply stating "proposed administrator" is not enough.

Tie priority directly to the will or intestacy statutes.

Items 11–12: Bond

Do not assume bond is waived. Confirm that the will waives bond or that all beneficiaries have waived it. If neither applies, bond is required.

Courts regularly reject petitions where bond is marked "not required" without support.

Items 13–14: Authority Requested

Indicate whether you are requesting full or limited authority. This affects the personal representative's ability to act without further court approval.

Item 15: Estimated Estate Value

List the gross value of probate assets. Do not subtract mortgages, liens, or debts. Estimates are acceptable, but they must be reasonable.

Use our fee calculator to see how estate value affects statutory fees.

Items 16–17: Heirs and Beneficiaries

List all heirs, even if they do not take under the will. This section drives notice requirements, so completeness matters.

Signature and Attachments

Attach the will, codicils, and any additional pages. Review the entire petition once more for consistency before signing.

Common Mistakes That Cause Rejections

• Incorrect venue
• Missing original will
• Bond incorrectly waived
• Incomplete heir listings
• Name inconsistencies across sections

These are procedural errors, not legal failures. They are avoidable with a checklist-based approach.

Filing Requirements by County

While DE-111 is statewide, counties differ on e-filing, local forms, courtesy copies, and hearing reservations. Always check local probate rules before filing.

What Happens After Filing

After filing, the court sets a hearing date. Notice is published and served. Proofs of service are filed. If the matter is uncontested, the hearing is usually brief, and Letters issue shortly thereafter.

Using Tools to Reduce Errors

Many attorneys struggle with their first DE-111 because they are filling it manually without validation. Guided tools that auto-fill fields and flag inconsistencies can significantly reduce rejections.

Frequently Asked Questions

Can I amend a DE-111?

Yes, but amendments delay the case and often require additional filings. It is better to file accurately the first time.

Does every probate require a hearing?

Most formal probates do, although uncontested hearings are typically short.

Can DE-111 be e-filed?

Many counties allow e-filing, but rules vary by county.

Is DE-111 used for trust administrations?

No. It applies only to probate estates.

Final Thoughts

The DE-111 form is not difficult once you understand what each section is asking and why. For attorneys filing their first probate, mastering this petition removes the biggest psychological barrier to handling probate work confidently.

Probate rewards preparation, consistency, and process. If you approach DE-111 that way, it becomes routine rather than intimidating.
