How to Fill Out California Form DE-165 (w/Examples) + FAQs

You fill out California Form DE-165 by listing the personal representative, the estate, the specific proposed action, the date the action will be taken, and serving it on every interested party at least 15 days before acting under the Independent Administration of Estates Act. The form is the Notice of Proposed Action under California Probate Code §10580 and it lets an executor or administrator act without prior court approval, unless an heir files a written objection.

This single piece of paper carries serious weight, because California Probate Code §10589 lets any beneficiary stop a sale, lease, or transfer just by mailing back a signed objection within 15 days. According to the Judicial Council of California 2024 Court Statistics Report, more than 38,000 probate cases are filed each year in California, and the majority use independent administration, which means DE-165 is one of the most-used probate forms in the state.

What Form DE-165 Is and Why It Exists

Form DE-165 is the Notice of Proposed Action that a California personal representative serves on heirs, devisees, and other interested parties before taking certain actions without a court hearing. The form lives inside California’s Independent Administration of Estates Act, which the Legislature passed in 1987 to speed up probate and cut court costs. Before the IAEA, every sale, lease, or borrowing required a noticed motion, a hearing, and a judge’s order, which often added six months to a case.

The plain-English purpose is simple: the executor tells everyone, “I plan to do this on or after this date, and if you object, you have 15 days to say so.” This pre-action notice replaces the old court hearing, but it preserves every beneficiary’s right to drag the action back into court. The consequence of skipping the form is severe, because under Probate Code §10590 the personal representative may face surcharge, removal, and personal liability for any loss.

A real example helps. Imagine Maria Lopez serves as executor of her father’s estate in Riverside County. She wants to sell the family home in Moreno Valley for \$650,000 to a cash buyer. She mails DE-165 to her three siblings on June 1, lists a proposed action date of June 17, and none of them object. She closes escrow on June 20 with no court appearance and no judge’s signature. That is the entire point of the form working as designed.

A common misconception is that DE-165 grants power to act, but that is wrong, because the power flows from the Letters Testamentary issued under Probate Code §10450. The notice only documents that the representative gave the legally required heads-up. Without valid letters granting full or limited authority, the form is meaningless paper.

Full vs. Limited IAEA Authority

The court grants either full or limited authority on Form DE-140 (Letters), and the difference controls which proposed actions DE-165 can cover. Full authority lets the representative sell real property, exchange property, and borrow money secured by real estate, all with a Notice of Proposed Action. Limited authority blocks all four of those real-estate powers and forces the representative to file a separate petition for sale.

The consequence of confusing the two authorities is that a sale closed on a defective DE-165 can be unwound, and title insurers refuse to insure the deed. James Chen discovered this when he tried to sell a Pasadena duplex with limited authority and a DE-165, and Chicago Title rejected the policy until he filed a Petition for Order Confirming Sale on Form DE-260. The mini-lesson is to read your Letters first, every time.

A frequent misconception is that the court “upgrades” authority automatically when an executor needs it, but that never happens, because Probate Code §10454 requires a noticed petition to expand authority. Filing the wrong form delays sales by 30 to 60 days in busy counties like Los Angeles.

Who Must Receive the Notice

Probate Code §10581 lists the people entitled to notice, and the list is broader than most first-time executors realize. It includes every known heir, every devisee under the will, anyone who has filed a Request for Special Notice on Form DE-154, and any person whose interest would be affected by the action. The personal representative is not required to serve themselves, even if they are also a beneficiary.

The consequence of missing one person is that the action becomes voidable as to that person, and the omitted heir can sue for damages or to set aside the sale. Aisha Williams learned this when she forgot to serve her estranged half-brother, and a judge in Alameda County voided the sale of a Berkeley triplex two years after closing. The buyer sued Aisha personally for \$180,000 in lost equity.

A common misconception is that minor children do not need notice, but the rule is the opposite, because minors must be served through a parent or guardian ad litem under Probate Code §1003. Skipping a minor heir is the fastest way to invalidate a notice.

Step-by-Step Walk-Through of Form DE-165

The current Judicial Council version of Form DE-165 was last revised January 1, 2020, and you can download it free from the California Courts website. The form has two pages, and every page must be completed, signed, and served. Skipping page two is the single most common reason clerks reject filings.

Caption Box (Top of Page 1)

The caption box is the same on every California probate form, but small mistakes here invalidate everything below. Enter the attorney’s name, state bar number, firm name, address, telephone, fax, email, and the party represented in the box marked Attorney or Party Without Attorney. Self-represented executors write “In Pro Per” on the bar number line.

The court name must match the exact branch where the case is filed, because Los Angeles County alone has eleven probate courthouses and the wrong branch triggers rejection. The estate name appears as “ESTATE OF [DECEDENT NAME], DECEASED,” in all caps, and the case number must match the original petition exactly.

The consequence of a caption error is that the clerk rejects the filing, mail goes out late, and the 15-day clock never starts. Kenji Tanaka lost a cash buyer in Orange County because he wrote the wrong case number and had to re-serve everyone, which pushed escrow past the buyer’s loan-lock deadline.

Item 1: Personal Representative Information

Item 1 asks for the name of the personal representative and whether they are an executor, administrator, administrator with will annexed, or special administrator. Check only one box, because checking two boxes signals the clerk that the representative does not understand their own appointment. The name must match the Letters issued by the court exactly, including middle initial.

The consequence of a name mismatch is challenge by any heir, who can argue the notice was issued by someone other than the appointed representative. The plain-English fix is to keep a copy of your Letters Testamentary next to you while filling out every probate form for the rest of the case.

A common misconception is that co-executors can each sign separate notices, but Probate Code §9630 requires all co-representatives to act jointly unless the will or court order says otherwise. Both signatures belong on the same DE-165.

Item 2: Authority Granted

Item 2 asks the representative to check whether the court granted full authority or limited authority under the IAEA. This single checkmark controls every other line on the form, because limited authority bars real-property sales, exchanges, options, and borrowings secured by real estate. Look at the face of your Letters Testamentary and copy that authority exactly.

The consequence of checking the wrong box is fraud on the court, even if accidental. Sofia Ramirez checked “full authority” when her Letters showed limited authority, and the title company caught the error. The transaction collapsed, and Sofia paid \$4,200 in cancelled escrow fees out of pocket because the estate refused to reimburse her.

A common misconception is that “full authority” applies whenever the will says “I grant my executor all powers under the IAEA,” but the will alone does not grant authority. The court must affirmatively grant it on Form DE-140, and limited authority is the default whenever a bond is waived only as to personal property.

Item 3: Description of Proposed Action

Item 3 is the longest box on the form, and it must describe the proposed action with enough detail that any reasonable beneficiary can understand exactly what will happen. For a real-estate sale, include the property address, APN, sale price, buyer name, commission percentage, escrow holder, and any seller credits. For a lease, include the term, monthly rent, security deposit, and tenant name.

The consequence of a vague description is that an objection forces the action back to court, where the judge applies a “fair and reasonable” standard and may set aside the action. The plain-English rule is to write the description as if you were explaining it to a stranger, not to yourself, because the heirs receiving the notice may live out of state and have never seen the property.

David Park serves as administrator of a Sacramento estate and lists “sale of decedent’s residence for fair market value” with no address or price. His sister objects, and the court rules the description was inadequate. David must re-serve, wait another 15 days, and pay \$2,800 in extra attorney fees.

Item 4: Date on or After Which Action Will Be Taken

Item 4 asks for the earliest date the representative may act, and that date must be at least 15 days after the notice is mailed or personally served. Count calendar days, not court days, and do not count the day of mailing. If the 15th day lands on a weekend or court holiday, action cannot be taken until the next court day under Code of Civil Procedure §12a.

The consequence of a short notice period is automatic invalidity, and any heir can later sue to unwind the action. Priya Patel mailed notice on March 3 and listed March 17 as the action date, which is only 14 days. Her brother caught the error, objected, and Priya had to re-serve and wait another full cycle.

A common misconception is that “15 days” means 15 business days, but the statute uses calendar days. Always add a buffer of two or three extra days to absorb mail delays, which is especially important when serving heirs in rural areas or out of state.

Item 5: Description of Property and Material Terms

Item 5 only applies when the proposed action is a sale, lease, exchange, or option of real or tangible personal property. It requires the legal description, address, sale price, broker, commission, escrow company, and all material terms of the deal. Attach the purchase agreement as Exhibit A whenever possible.

The consequence of leaving Item 5 blank when it applies is the same as a vague Item 3, because heirs cannot evaluate fairness without the numbers. Marcus Johnson attached a redacted purchase agreement that hid the buyer’s name, and the court ruled the redaction violated the disclosure requirement of Probate Code §10583.

A common misconception is that off-market sales to family members do not require Item 5 detail, but insider sales actually require more detail, because Probate Code §9881 governs self-dealing and demands full disclosure of the relationship.

Item 6: Signature, Date, and Capacity

Item 6 carries the personal representative’s signature, the date of signing, and the capacity (executor, administrator, etc.). The signature must be original ink for any notice that will be filed with the court, although mailed copies to heirs may bear a photocopy of the signature. Some counties, such as San Francisco, accept electronic signatures under California Government Code §16.5.

The consequence of an unsigned form is that no valid notice was ever served, and the 15-day clock never starts. Linda Nguyen mailed an unsigned DE-165 to four heirs, and her sale collapsed when the title company demanded a signed original. She lost 18 days and the original cash buyer.

Page 2: Objection Form (To Be Returned by Heir)

Page 2 of DE-165 is the Objection to Proposed Action, which the heir fills out, signs, and mails back if they want to stop the action. The representative must include this entire page in every envelope, because failing to include the objection form is itself a procedural violation. The page lists the heir’s name, the date received, the specific objection, and the heir’s signature.

The consequence of omitting page 2 is that the notice is technically defective, and a sophisticated heir or their attorney can later argue they were denied a meaningful chance to object. The plain-English fix is to staple all four pages (the two-page form plus a self-addressed stamped envelope and a copy of the purchase agreement) into one packet for every heir.

A common misconception is that heirs can object by phone or email, but Probate Code §10587 requires a written objection delivered before the action date. An email may count as written notice in some courts, but mailing the actual page 2 is the safest practice.

Three Real-World Scenarios with Tables

The three most common DE-165 fact patterns in California probate are sale of the decedent’s home, lease of an inherited rental property, and abandonment of worthless personal property. Each scenario triggers different statutory hooks, different objection risks, and different consequences when something goes wrong. The tables below show the action paired with the most likely consequence under current California law.

Scenario 1: Selling the Decedent’s Home

Robert Garcia is the administrator of his mother’s San Diego estate, and he wants to sell her La Jolla condo for \$1.2 million to a buyer who toured the unit twice. He has full IAEA authority and three siblings as heirs. He prepares DE-165 with the full address, APN, price, buyer name, 5 percent commission, and 30-day escrow.

Step Robert Takes	Legal Outcome Under Probate Code
Mails DE-165 to all three siblings via first-class mail with proof of service	Triggers 15-day objection window under §10586
Receives no objection by day 16	May close escrow without court order under §10588
One sibling mails objection on day 10	Robert must petition for Order Confirming Sale under §10589

Scenario 2: Leasing an Inherited Rental

Hannah Kim serves as executor of her uncle’s estate in Long Beach, and she wants to lease his vacant fourplex for \$3,800 a month on a one-year term. The lease will generate rental income until the property is eventually sold. Because the lease term is under one year, IAEA authority covers it whether full or limited, under Probate Code §10511.

Lease Decision	Probate Consequence
Lease term under one year, fair market rent	DE-165 alone is enough, no court order needed
Lease term over one year or below market	Court petition required under §10511(b)
Lease to relative without disclosure	Self-dealing claim under §9881, possible surcharge

Scenario 3: Abandoning Worthless Property

Tommy Walsh is the special administrator of an estate that owns a 1998 Ford Taurus with a blown engine, three storage units full of damaged furniture, and a timeshare in Mexico with \$4,000 in back fees. Selling these assets would cost more than they are worth, so Tommy wants to abandon them under Probate Code §9780. He prepares DE-165 with a detailed inventory and an explanation of why each asset has negative value.

Asset Action	Estate Outcome
Abandon car to junkyard for \$0	Removes towing liability and storage fees
Abandon storage unit contents	Ends \$340 monthly storage charge
Abandon timeshare back to resort	Stops accrual of maintenance fees

Mistakes to Avoid When Filing DE-165

The mistakes below appear in published probate opinions and in the daily rejection logs of California probate clerks. Each one carries a distinct consequence, and most are entirely preventable with a simple checklist. The pattern across all of them is a representative who treated DE-165 as a formality rather than as a binding legal notice.

• Serving fewer than 15 calendar days before the action date. The action is voidable, and any heir can sue to unwind it under Probate Code §10589.
• Forgetting to serve a known heir. The action is voidable as to that heir, and the representative may face personal surcharge under Probate Code §9601.
• Checking the wrong authority box (full vs. limited). Title insurers refuse coverage, escrow collapses, and the representative pays cancellation fees personally.
• Writing a vague description in Item 3. A heir’s objection forces a court hearing, adds 30 to 60 days, and costs \$2,000 to \$5,000 in extra attorney fees.
• Omitting page 2 (the objection form) from the mailed packet. The notice is procedurally defective, and a later objection can void the entire action.
• Skipping the proof of service. Without Form POS-030 on file, the representative cannot prove the 15-day clock ever started.
• Acting before the 16th day. Even one day early is a clear violation, and the action is voidable on its face.
• Failing to disclose self-dealing or insider buyer. Under Probate Code §9881, the action is presumed unfair and must be set aside.
• Using an outdated form revision. The Judicial Council updates probate forms every few years, and old versions are rejected by clerks in counties like Los Angeles and Santa Clara.

Do’s and Don’ts for Personal Representatives

The line between a clean independent administration and a contested probate often comes down to small habits during the DE-165 process. The do’s and don’ts below come from California probate referees, court investigators, and certified specialists in estate planning, trust, and probate law accredited by the State Bar of California Legal Specialization Board.

Do’s

• Do mail every notice with proof of service on Form POS-030, because oral notice is never enough under §10586.
• Do keep a calendar with day 1 through day 16 marked, because miscounting is the most common mistake in pro per cases.
• Do attach the full purchase agreement, lease, or contract, because heirs cannot evaluate fairness from a one-line description.
• Do verify your Letters Testamentary authority before checking Item 2, because the wrong box invalidates the entire form.
• Do consult a probate attorney for any action over \$100,000, because the cost of a one-hour review is far less than the cost of a contested objection.

Don’ts

• Don’t rely on email or text for service, because Probate Code §1215 requires mail or personal delivery for most notices.
• Don’t sell to yourself, your spouse, or a business you own without separate court approval, because self-dealing voids the transaction.
• Don’t shorten the notice period even if every heir verbally agrees, because verbal waivers are unenforceable without a signed Form DE-166.
• Don’t alter the Judicial Council form layout, because clerks reject modified forms on sight under California Rules of Court 1.31.
• Don’t wait until day 14 to mail, because a single postal delay can blow the entire timeline and force re-service.

Pros and Cons of Using DE-165

The Notice of Proposed Action is the single most powerful efficiency tool in California probate, but it shifts risk from the court to the personal representative. Understanding both sides helps the representative decide when to use DE-165 and when to file a noticed petition instead. The trade-off becomes especially important for high-value or contested estates.

Pros

• Speed because no court hearing is required, saving 30 to 90 days in busy counties.
• Cost savings because the representative avoids \$435 filing fees and 2 to 5 hours of attorney prep time per action.
• Privacy because the action does not appear on the public probate calendar and avoids press attention.
• Flexibility because the representative controls timing and can act the day after the 15-day window closes.
• Beneficiary inclusion because heirs receive full disclosure and a meaningful chance to object before the action.

Cons

• Personal liability because the representative bears the risk of getting the form wrong under §10590.
• Strict 15-day timing because even one day short voids the action regardless of intent.
• No judicial blessing because the representative cannot point to a court order if the action is later challenged.
• Limited scope because some actions, like sales of property worth more than the inventory value, still require court confirmation.
• Insurance friction because some title insurers in 2026 still demand court confirmation regardless of IAEA authority, especially after the Estate of Stevens ruling tightened scrutiny of insider sales.

Key Entities Involved in the DE-165 Process

The probate ecosystem includes more players than most first-time representatives realize, and each one has a defined role under the Probate Code. The personal representative is the central actor, but the court, the probate referee, the heirs, the bond company, and the title insurer each shape how DE-165 is used. Understanding these relationships prevents most rookie mistakes.

The Judicial Council of California creates and updates DE-165 itself, and clerks across all 58 counties enforce its current revision. The California Probate Referees Association appoints referees who appraise non-cash assets, and their appraisal sets the floor for any sale price disclosed in Item 5. The State Bar of California regulates the attorneys who advise representatives, and the California Department of Real Estate licenses the brokers who often handle the underlying sales.

The personal representative owes fiduciary duties to every heir under Probate Code §9600, and those duties continue throughout the entire DE-165 process. The bond company, if a bond is required, can demand documentation of every notice before it pays a claim. The title insurer is the final gatekeeper for any real-estate sale, and most major California insurers, including Chicago Title and First American, maintain probate underwriting standards that often exceed the statutory minimum.

Recap of Relevant Court Rulings

California appellate courts have shaped DE-165 practice through a series of opinions that every representative should know in summary form. Estate of Hilton (1996) confirmed that the 15-day period is jurisdictional, meaning courts cannot waive it even when every heir consents on the record. Estate of Stevens (2002) held that an insider sale to the executor’s spouse, even with a DE-165 served and no objections received, is voidable because the duty of loyalty under §9600 is independent of the notice statute.

Estate of Bonaccorsi (1999) upheld a surcharge against an executor who served notice but failed to attach the purchase agreement, which the court called “the kind of material omission that turns a notice into a trap.” The lesson across all three cases is that perfect procedure is necessary but not sufficient, because substantive fairness is reviewed independently. The plain-English rule is that DE-165 protects the representative only when both the form and the underlying deal are above board.

A common misconception is that the absence of objection equals court approval, but the cases above prove that wrong. An heir who sees a DE-165, says nothing, and later discovers self-dealing or below-market pricing can still sue to set aside the action, sometimes years later under Code of Civil Procedure §338.

Federal Tax and Reporting Overlay

Although DE-165 is a California state form, the underlying actions often trigger federal tax consequences that the representative must coordinate with the IRS. A sale of real property may trigger capital gains under Internal Revenue Code §1014, which generally provides a stepped-up basis at date of death. The representative reports the sale on the estate’s Form 1041 for the year of sale.

The consequence of ignoring the federal overlay is double taxation, missed deductions, and possible IRS penalties. Elena Rodriguez sold her father’s Pasadena home through a clean DE-165 process but forgot to file Form 1041, and the IRS assessed \$8,400 in late-filing penalties two years later. The fix would have cost \$600 in CPA time at the start of the case.

A common misconception is that the estate’s federal employer identification number is optional, but IRS Publication 559 requires every probate estate to obtain an EIN before opening an estate bank account. Without an EIN, the representative cannot deposit sale proceeds, and escrow will not close.

County-Specific Local Rules

California has 58 counties, and each superior court can adopt local rules that supplement the Judicial Council forms. Los Angeles Superior Court Local Rule 4.7 requires probate filings to include a probate notes review, which can add two weeks to a contested DE-165 process. Orange County Local Rule 605 requires sale notices to include a comparative market analysis when the property is residential.

Alameda County and San Francisco County accept electronic filing of DE-165, which speeds the entire process by 5 to 10 days. San Bernardino County requires paper filing in most probate matters, which means the representative must factor in mail time on both ends. The plain-English rule is to check the local rules of your specific county before mailing the first envelope.

The consequence of ignoring local rules is rejection at the clerk’s window, which restarts the entire 15-day clock. Carlos Mendoza filed a DE-165 in Riverside County without the required local cover sheet, and the clerk rejected it on day 12. He had to refile and remail, losing nearly three weeks on a hot escrow.

FAQs

Is California Form DE-165 required for every probate estate?

No. The form is only required when the personal representative wants to take a specific action under the IAEA without a court hearing. Estates with court-supervised administration use noticed petitions instead.

Can heirs waive the 15-day notice period in writing?

Yes. Heirs may sign a Waiver of Notice on Form DE-166, which lets the representative act immediately. Every heir entitled to notice must sign or the waiver is incomplete.

Does the representative need a lawyer to prepare DE-165?

No. California allows pro per representatives, but probate is technical, and most attorneys charge a statutory fee under Probate Code §10810. Self-help centers in most counties offer free guidance.

Is electronic service of DE-165 valid in California?

Yes. Many counties accept electronic service when the recipient consents in writing, under Code of Civil Procedure §1010.6. Without written consent, mail or personal service is required.

Can a beneficiary withdraw an objection after filing it?

Yes. A beneficiary may withdraw a written objection at any time before the court rules, simply by signing and mailing a withdrawal notice. The representative may then proceed without further delay.

Does DE-165 apply to trust administration?

No. Trusts use a separate notice procedure under Probate Code §16061.7. The DE-165 form is exclusively for probate estates administered under the IAEA.

Is the 15-day period extended for out-of-state heirs?

Yes. Under Code of Civil Procedure §1013, the period is extended by 5 days for out-of-state mail service and 10 days for foreign service. The representative must add this buffer to the action date.

Can DE-165 be used to sell property below appraised value?

No. A sale below the probate referee’s appraisal requires court confirmation, regardless of IAEA authority. The representative must file a Petition for Order Confirming Sale instead.

Does the representative file DE-165 with the court?

Yes. The form is mailed to heirs and filed with the court along with proof of service on Form POS-030. Some counties accept later filing with the final account.

Is a notarized signature required on DE-165?

No. California probate forms generally do not require notarization, but the signature must be the original signature of the personal representative. Notarization is a common but unnecessary precaution.
