How to Complete a Probate Petition in California
Completing a probate petition in California involves more than filling out a single court form. Form DE-111, Petition for Probate, is the core document used to ask the court to open a probate case, but DE-111 is only one part of a complete probate petition packet.
This guide explains how to complete a probate petition in California, from gathering the right information to preparing the DE-111 form and the attachments that support it. To complete a probate petition in California correctly, you must gather information about the decedent, identify heirs and beneficiaries, provide preliminary estate information, select the authority you are requesting, address bond requirements, and prepare any required attachments and supporting forms.
The court reviews these documents together. Information on DE-111 must remain consistent with the will, attachments, notices, and other documents you submit with the petition. Missing information or conflicting answers can result in probate examiner notes and delays.
This guide explains how to fill out DE-111, what information you need before you begin, which probate petition attachments may be required, and how to prepare the supporting paperwork that makes up a California probate petition packet.
If you are looking for the steps that come after the paperwork is prepared, including filing the petition, notice, publication, the court hearing, and issuance of Letters, see our practical guide to filing a Petition for Probate in California.
This article explains the preparation and structure of probate petition paperwork. It does not cover estate administration or asset distribution.
Form DE-111: The Core California Petition for Probate
Every California probate petition packet centers on Form DE-111, Petition for Probate. Petitioners use this primary Judicial Council form to ask the probate court to open a formal probate case and appoint a personal representative.
DE-111 is the foundation of the petition packet, but it is not necessarily the entire petition. Information on the form may require attachments, supporting documents, or additional court forms depending on the estate and the petitioner’s requests.
What Form DE-111 Tells the Probate Court
The DE-111 Petition for Probate provides the court with essential information about the decedent, the petitioner, the estate, and the orders being requested. Among other things, DE-111 identifies:
The answers on DE-111 establish the basic framework for the probate case. However, completing the form correctly requires gathering the underlying information before you begin and understanding how the answers relate to the rest of the petition packet.

How to Fill Out the Key Parts of Form DE-111
Form DE-111, Petition for Probate, asks for information that establishes the basic facts of the probate case and tells the court what orders you are requesting. When you fill out DE-111, each section should be completed with the rest of the petition packet in mind.
Petitioner and Attorney Information
The first part of DE-111 identifies the person asking the court to open the probate case. A self-represented petitioner provides their own contact information rather than attorney information. Use consistent names and contact information throughout the petition packet. Differences in names, initials, addresses, or other identifying information can create questions when the court compares documents.
Court and Decedent Information
DE-111 identifies the decedent and the California Superior Court where you will file the petition. Use the decedent’s full legal name consistently and provide the information needed to establish the proper county for probate. The county generally depends on where the decedent was domiciled at death. Domicile means the person’s permanent legal residence, which is not always the same as where the person happened to die.
What You Are Asking the Court to Do
One of the most important parts of DE-111 tells the court what orders the petitioner requests. This includes the type of probate proceeding and who should be appointed to administer the estate. The requested appointment depends in part on whether the decedent left a will and whether that will nominates an executor. When there is no will, the petitioner may instead request appointment of an administrator. The selections on DE-111 should match the facts elsewhere in the petition and any will you submit to the court.
Information About the Will
If the decedent left a will, DE-111 requires information about the document and the person nominated to serve as executor. Any codicils must also be considered. Review the will carefully before completing this portion of the petition. The will may contain provisions concerning the nominated executor, bond, or authority to administer the estate that affect other answers on DE-111. If there is no will, the court generally treats the estate as intestate. Different priority rules may then determine who may serve as administrator.
Heirs, Beneficiaries, and Family Relationships
The petition must accurately identify people whose legal rights the probate proceeding may affect. To do that, understand the difference between an heir and a beneficiary. An heir is someone who would inherit under California intestate succession law if there were no valid will. By contrast, a beneficiary is a person or organization named to receive property under a will. Even when a will exists, legal heirs may still need to be identified. Do not assume that listing only the beneficiaries named in the will is sufficient. Family relationships should be reviewed carefully. A relative who died earlier, a predeceased child, a minor, or another family circumstance can affect what information the petition must provide.
Estimated Value of the Probate Estate
DE-111 asks for preliminary estimates of the value of property subject to probate. These figures help the court understand the approximate size and composition of the estate. Separate real property from personal property. Use reasonable estimates based on the information available when you prepare the petition. These preliminary figures are not the same as the formal values later reported through the probate Inventory and Appraisal. The petition stage comes before that formal appraisal process.
Full or Limited Authority Under the IAEA
A petitioner may request authority under California’s Independent Administration of Estates Act (IAEA). Depending on the circumstances, that request may be for full authority or limited authority. This choice affects what the personal representative may later do without obtaining separate court approval for certain estate transactions. The selection on DE-111 should therefore reflect the authority the petitioner actually requests. Do not treat it as a routine checkbox. For a more detailed explanation, see our guide to full vs. limited authority under the IAEA.
Bond Information
DE-111 also addresses whether the court will require the proposed personal representative to post a bond. A probate bond helps protect the estate against certain losses caused by the personal representative. Several factors can affect bond, including provisions in the will, the type of appointment, and whether the court permits a waiver. Information concerning bond should remain consistent throughout the petition and supporting documents. If the petition asks the court not to require bond, the paperwork should clearly support that request.
Attachments and Additional Explanations
Not every answer fits neatly into the space provided on DE-111. Some circumstances require additional information or an attachment. When an attachment is necessary, clearly identify the DE-111 item it relates to. The information should supplement the form rather than contradict or unnecessarily repeat it.
Before considering DE-111 complete, review the form together with every attachment and supporting document. Names, dates, relationships, asset information, authority requests, and bond information should tell the same story throughout the probate petition paperwork.
How to List Heirs and Beneficiaries on a California Probate Petition
Accurately identifying heirs and beneficiaries is one of the most important parts of preparing Form DE-111 and the probate petition paperwork. A common mistake is listing only the people who will receive property under the will.
Beneficiary
A person or organization named to receive property under a will.
Heir
Someone who would inherit under California intestate succession law if the decedent had died without a valid will.
Because these groups can be different, a probate petition may need to identify people who are legal heirs even though they receive nothing under the will. For example, if a decedent died without a surviving spouse or children, preparing the petition may require identifying the next level of legal heirs, which can include the decedent’s parents, even if they died before the decedent.
Information to Gather for Each Heir and Beneficiary
Do not assume that a person can be omitted simply because they are not receiving property under the will. Identifying the correct heirs and beneficiaries is part of preparing a complete California probate petition packet.
Why Complete and Consistent Probate Petition Paperwork Matters
After you file a probate petition, the court reviews the paperwork for completeness and consistency. Missing information, conflicting answers, or incomplete attachments can create deficiencies. You must correct those deficiencies before the petition can move forward.
This is why the preparation stage matters. Before filing, review Form DE-111, probate petition attachments, supporting forms, and local court documents together. Names, dates, family relationships, asset information, authority requests, and bond information should remain consistent throughout the packet.

Common DE-111 and Probate Petition Preparation Mistakes
Even when Form DE-111 appears complete, problems elsewhere in the petition packet can create inconsistencies. Many petition problems begin with preparation errors rather than disputes about the estate.
Mistake 1
Inconsistent Names, Dates, or Other Information
Information should remain consistent across DE-111, attachments, the will, and supporting forms. Differences in names, dates, family relationships, addresses, or other important facts can create questions about which information is correct.
Mistake 2
Missing or Incomplete Heir Information
Listing only the beneficiaries named in a will can leave the petition incomplete. California probate petitions may also require information about legal heirs, including people who will not receive property under the will. Review family relationships carefully before completing DE-111 and any related attachments.
Mistake 3
Missing Probate Petition Attachments
DE-111 does not always provide enough space or information to explain every circumstance. When additional information or an attachment is required, completing the main form alone does not create a complete petition packet. Make each attachment clearly correspond to the part of DE-111 it supplements.
Mistake 4
Mixing Probate and Non-Probate Assets
The preliminary asset information on DE-111 should generally reflect property expected to pass through probate. By contrast, including trust assets, certain jointly owned property, or accounts that pass through valid beneficiary designations can distort the estimated probate estate.
Mistake 5
Authority Requests That Do Not Match the Petition
A request for full or limited authority under the Independent Administration of Estates Act should be consistent with the rest of the petition paperwork and the circumstances of the estate. Do not treat the authority selection as an isolated checkbox. Review it together with the will and the other information provided in the petition.
Mistake 6
Inconsistent or Unsupported Bond Information
Bond information should be reviewed across DE-111, the will, applicable waivers or attachments, and other supporting documents. A request concerning bond should be consistent with the information contained elsewhere in the petition packet.
Mistake 7
Overlooking Local Court Requirements
Statewide Judicial Council forms may not be the only paperwork needed. Before finalizing the petition, check whether the county where the case will be filed has additional local forms or requirements.
Mistake 8
Treating DE-111 as a Standalone Form
Perhaps the biggest preparation mistake is reviewing DE-111 by itself. Review the petition as a complete packet. Before the paperwork is ready for filing, compare DE-111 with every attachment and supporting document. Names, dates, relationships, asset information, authority requests, and bond information should tell one clear and consistent story.
Frequently Asked Questions About Completing a Probate Petition in California
Form DE-111 and the Probate Petition Packet
What is Form DE-111 in California probate?
Form DE-111, Petition for Probate, is the primary California Judicial Council form used to ask the probate court to open a formal probate case and appoint a personal representative. It provides information about the decedent, petitioner, will, heirs and beneficiaries, estimated probate assets, requested authority, and bond. It forms the foundation of the petition packet, but you may also need additional forms and attachments.
How do I fill out Form DE-111 in California?
Before filling out DE-111, gather information about the decedent, the original will and any codicils, heirs and beneficiaries, probate assets, the proposed personal representative, requested authority, and bond. Complete each section using consistent information and review DE-111 together with all attachments and supporting forms before filing.
Is DE-111 the only form needed to start probate in California?
No. DE-111 is the core Petition for Probate, but it is not necessarily the entire petition packet. Depending on the estate and the county, you may need additional Judicial Council forms, probate petition attachments, the original will and codicils, and applicable local court forms.
Attachments, Heirs, and Estate Information
What probate petition attachments may be required with DE-111?
The required attachments depend on the facts of the estate. An attachment may be necessary when DE-111 does not provide enough space to explain family relationships, heir information, authority, bond, a will or codicil, or other circumstances. Each attachment should clearly identify the DE-111 item it supplements and remain consistent with the rest of the petition paperwork.
Do I list both heirs and beneficiaries on a California probate petition?
You may need to identify both. An heir is someone who would inherit under California intestate succession law if there were no valid will. A beneficiary is a person or organization named to receive property under a will. Even when a will exists, the petition may require information about legal heirs who receive nothing under the will.
What asset values should I include on Form DE-111?
DE-111 asks for preliminary estimates of the real and personal property expected to pass through probate. You generally do not prepare the formal appraisal at this stage. Use reasonable estimates based on the information currently available. The more detailed valuation occurs later through the probate Inventory and Appraisal process.
Local Court Requirements and Document Preparation Help
Does every California county require the same probate petition paperwork?
No. California courts use statewide Judicial Council forms, including DE-111, but individual Superior Courts may have additional local forms or requirements. Check the requirements for the county where you will file the probate case before finalizing the petition packet.
Can a Legal Document Assistant help prepare Form DE-111 and probate petition paperwork?
Yes. A California Legal Document Assistant can prepare probate documents at the direction of a self-represented petitioner. Probate & More can help prepare DE-111, supporting forms, probate petition attachments, heir and beneficiary information, and applicable county-specific forms consistent with local filing requirements. An LDA does not provide legal advice or represent you in court.
Conclusion: Completing a Probate Petition in California
Completing a probate petition in California means more than filling in the blanks on Form DE-111. A complete petition packet may include supporting forms, attachments, information about heirs and beneficiaries, preliminary asset values, authority and bond information, and documents required by the local court.
The most important goal is consistency. Names, dates, family relationships, asset information, and requests on DE-111 should align with the supporting probate petition paperwork. Review the documents together before filing to identify missing information or conflicting answers.
