Essential Documents Checklist for Probate Administration

Getting probate started in California requires several key documents. Some need to be filed with the court, while others are used to notify creditors, financial institutions, and heirs. Here’s what you’ll need:

1. Certified Copy of the Death Certificate

This is the most basic but crucial document. Banks, insurance companies, and government agencies all require proof of death before releasing information or funds.

Where to Get It?

  • You can order copies through the California Department of Public Health (CDPH) or the county recorder’s office where the person passed away.
  • Funeral homes often help with obtaining them. It’s a good idea to request multiple copies—most institutions will need an original, not a photocopy.

2. Petition for Probate (Form DE-111)

This form officially starts the probate case. It asks the court to recognize a personal representative (executor or administrator) who will handle the estate.

What You’ll Need to Provide:

  • Basic details about the deceased person (date of death, place of residence).
  • Whether your client had a will or not.
  • A general estimate of the estate’s value.

Once completed, this petition must be filed with the probate court in the county where your loved one lived.

3. Original Will (If There Is One)

If the deceased person had a will, the original document must be lodged with the court within 30 days of death.

What If the Will Is Lost?

  • If you have a copy, you can submit it along with an explanation of why the original is missing.
  • If there’s no will at all, the estate will be handled under California intestacy laws, meaning assets go to heirs based on a legal order of priority.

4. Notice of Petition to Administer Estate (Form DE-121)

This document notifies heirs, beneficiaries, and creditors that probate has been filed. It must be sent to everyone named in the will (or those who would inherit under intestate succession).

Publication Requirement:

  • The notice also needs to be published in a newspaper in the county where probate is being handled.
  • This alerts any unknown creditors or interested parties.

5. Duties and Liabilities of Personal Representative (Form DE-147)

This form explains your responsibilities as the person handling the estate, whether you are an executor (named in a will) or an administrator (appointed by the court if there’s no will). 

It must be signed and filed with the court before the personal representative can start managing estate assets.

6. Confidential Statement of Birth Date & Driver’s License Number

Probate courts require this form to verify the identity of the personal representative. This helps prevent fraud and ensures that only authorized individuals can handle estate matters.

7. Request for Appointment of a California Probate Referee (Local Form PR-5)

As a probate referee, you will be assigned by the court to appraise non-cash assets, such as:

  • Real estate
  • Business interests
  • Stocks and bonds
  • Other valuable personal property

This form requests the appointment of a probate referee, who will determine the fair market value of these assets.

8. Bond (If Required)

Not every probate case requires a bond, but courts may require the personal representative to obtain one, especially if:

  • The will does not explicitly waive the bond requirement.
  • The personal representative is not a close family member.
  • There are concerns about financial responsibility.

A bond acts as insurance to protect heirs and creditors if the personal representative mishandles estate funds.

9. Order for Probate (Form DE-140)

Once the court reviews all filings and holds a hearing, it will issue this order. This document officially authorizes the personal representative to manage and distribute the estate.

10. Letters Testamentary or Letters of Administration

These legal documents grant authority to act on behalf of the estate. Without them, financial institutions and other entities won’t release assets.

  • Letters Testamentary are issued when there’s a will.
  • Letters of Administration are issued when there’s no will.

11. Inventory and Appraisal (Form DE-160)

This form provides a detailed list of everything in the estate, including:

  • Bank accounts
  • Real estate
  • Vehicles
  • Jewelry, collectibles, and other personal items

It’s submitted with values assigned by your probate referee, ensuring everything is properly accounted for.

Common Challenges Regarding Probate Administration Documents

Even with all the proper documents, probate can still hit roadblocks. Here are some common issues and how to handle them:

  • Lost Will: If the original is missing, a copy may be used if witnesses can verify its authenticity. Otherwise, the estate is treated as intestate.
  • Heir Disputes: When family members disagree over the estate, mediation or court intervention may be necessary.
  • Complicated Asset Valuations: Certain assets, like family businesses or rare collections, require professional appraisals.
  • Will Contests: If someone challenges the will’s validity, one must prove fraud, undue influence, or lack of mental capacity.
  • Creditor Claims: Creditors have a limited window (typically four months after the probate notice is published) to submit claims.

The average probate case in California takes about 12 to 18 months, but complex estates can take longer. An experienced attorney can help minimize delays.
