California Probate Form DE-150, titled “Letters,” is the Judicial Council form that — once you complete it, sign the affirmation, post any required bond, and have the court clerk certify it after the judge signs the Order for Probate — becomes the legal proof of your authority to act as personal representative of an estate. Banks, title companies, and government agencies will not release assets on the strength of a court order alone. They want to see a certified copy of the Letters, stamped by the clerk, confirming your appointment is still in effect.
What the Letters Do
Under California Probate Code Section 8400, no one has power to administer an estate until they are appointed personal representative and that appointment “becomes effective” through the issuance of letters.1California Legislative Information. California Code 8400 – Appointment of Personal Representative Even someone named executor in the will cannot sell property, access bank accounts, or settle debts before the Letters are issued.
The reason third parties insist on the Letters is on the form itself. The clerk’s certification confirms the letters have “not been revoked, annulled, or set aside, and are still in full force and effect.”2Judicial Council of California. DE-150 Letters That language is what protects a bank when it hands over funds. Without it, an institution has no way to verify your authority is current, and it will refuse to release anything.
Which Box to Check
The DE-150 covers four categories of representative authority. Which one applies depends on whether there is a will and who the court appointed.
- Letters Testamentary are issued when the person named as executor in a valid will is appointed by the court.
- Letters of Administration with Will Annexed are issued when a will exists but does not name an executor, or the named executor cannot or will not serve.
- Letters of Administration are issued when the deceased died without a will.
- Letters of Special Administration are issued on a temporary basis when the court needs someone in place immediately, for example to prevent a foreclosure or manage a perishable asset while a will dispute is resolved.
A special administrator has notably less power than a general representative. Under Probate Code Section 8540, a special administrator can exercise only the powers the court specifically grants, and the appointment can be limited to a set term or particular tasks.3California Legislative Information. California Probate Code 8540 Once the court names a permanent representative, the special administrator’s authority ends.
Full or Limited IAEA Authority
The form also asks whether you have been granted authority under the Independent Administration of Estates Act, and if so, whether that authority is full or limited. This is not a preference. You check the box that matches what the judge granted in the Order for Probate.
Full authority under Probate Code Section 10402 lets the representative exercise all powers granted under the IAEA, including selling real property, without first obtaining a court order.4California Legislative Information. Independent Administration of Estates Act (IAEA) Advance notice to interested persons is still required for major actions, but the process is much faster than seeking formal approval each time.
Limited authority under Section 10403 strips out four specific powers over real property: selling it, exchanging it, granting an option to purchase it, and borrowing money secured by it. For any of those, a representative with limited authority must return to court for a separate order. When an estate includes real property that will need to be sold, that difference can add months and significant legal fees.
Filling Out the Form
You are responsible for the identifying information at the top of the form and the boxes indicating your type of authority. The clerk handles the certification block at the bottom.
- Enter the superior court name, county, street and mailing addresses, and branch name. This must match where the probate case is pending.
- Fill in the estate name (typically “Estate of [Decedent’s Full Legal Name]”) and the case number assigned when the petition was filed.
- Check the box for the type of letters the judge granted: testamentary, administration with will annexed, administration, or special administration.
- Check the IAEA authority box — full or limited — only if the court granted it. Leave it blank if it was not requested or not granted.
The most common mistake is a mismatch between the DE-150 and the Order for Probate. If the order says “limited authority” and you check “full,” the clerk will catch it, and you will be making a second trip.
The Affirmation and the Bond
Page two contains an affirmation where you sign a statement that you will “perform the duties of personal representative according to law.”2Judicial Council of California. DE-150 Letters This is a legal oath. It binds you to your fiduciary duties and exposes you to personal liability if you mismanage the estate. A public administrator is exempt from the affirmation; the official oath and bond of that office take its place.
Under Probate Code Section 8480, every personal representative must post a surety bond before the court will issue the letters.5California Legislative Information. California Probate Code 8480 The bond protects beneficiaries and creditors against mishandling of assets. Without it, the clerk will not issue the Letters.
Section 8481 allows the bond to be waived in two situations. The will itself may include waiver language, or, if it does not, all beneficiaries may waive the bond in writing and attach the waivers to the petition.6California Legislative Information. California Probate Code 8481 Even with a waiver, the court can still require a bond for good cause, particularly when the estate is large, when beneficiaries include minors, or when the court has concerns about the representative’s ability to manage assets. Surety companies typically calculate bond premiums as a percentage of the estate’s value.
Getting the Letters Issued and Certified
Completing the DE-150 does not give you any authority on its own. The form goes to the court clerk after the judge signs the Order for Probate (Form DE-140). The clerk reviews the DE-150 against the order, applies the court seal, and signs the certification. Only then do the Letters become active.
The original stays in the court’s permanent file. What you actually use are certified copies, each stamped and signed by the clerk confirming the letters remain in effect. California’s statewide fee for certifying a copy of any court document is $40 per copy under Government Code Section 70626(a)(4).7Superior Court of California. Statewide Civil Fee Schedule Order several at once. Each bank, brokerage, insurance company, and government agency may want its own copy, and many will not return them. Four to six is a reasonable starting point for a moderately complex estate; larger estates with more accounts may need more.
Some counties, including San Joaquin, accept e-filing for probate documents. Availability varies by court, so check with the clerk before assuming you need to appear in person. Even where e-filing is available, you will still pick up or request the certified copies separately.
Financial institutions often want a recently issued certified copy. Sixty days is a common informal cutoff, though no single statewide rule sets a freshness limit. If several months pass before you deal with a particular institution, expect to return to the clerk for fresh copies.
What to Do Once You Have the Letters
The Letters activate your authority and trigger several obligations that start right away.
Notify Known Creditors
Under Probate Code Section 9050, you must give notice of the estate administration to every known or reasonably ascertainable creditor.8California Legislative Information. California Probate Code 9050 A creditor is “known” if you are aware the creditor demanded payment from the decedent or the estate. This direct notice is separate from the general publication under Section 8120, which reaches unknown creditors through a newspaper of general circulation. Missing a known creditor can expose you to personal liability if that creditor later files a claim after assets have been distributed.
Open an Estate Account and Get an EIN
Open a dedicated bank account for the estate so its funds stay separate from your personal money. The bank will ask for a certified copy of the Letters and an Employer Identification Number from the IRS, which acts as the estate’s tax ID. You can apply for the EIN online at no cost using IRS Form SS-4.9Internal Revenue Service. Information for Executors The online application issues the EIN immediately.
Collect and Manage Assets
With Letters in hand, you can begin gathering assets, paying valid debts, and managing property: contacting financial institutions, transferring titles, canceling services, and filing tax returns for the estate. With full IAEA authority you can handle most of this without returning to court. With limited authority, real property transactions still need judicial approval. Keep detailed records of every transaction from day one. You will file an accounting with the court later, and the records you start now are what protects you when that time comes.
