California's Independent Administration of Estates Act (IAEA) is the difference between a probate home sale that closes in 45 days and one that takes nine months. I'm Brian Cooper, REALTOR(R) at eXp Realty (DRE# 01434286). I've handled probate listings in Ventura County for two decades, working with executors, administrators, and probate attorneys. The single biggest factor in how a probate sale runs is whether the personal representative has Full or Limited Authority under IAEA. This guide walks through both, the 90% appraisal rule, the Notice of Proposed Action process, and how overbidding works at the confirmation hearing.
Quick Answer
The Independent Administration of Estates Act (IAEA), codified at California Probate Code sections 10400 through 10592, lets a personal representative (executor or administrator) handle most estate transactions without going back to court for each one. The court grants either Full Authority or Limited Authority when Letters Testamentary are issued.
Full Authority means the personal representative can sell real property without a court-confirmation hearing, provided they send a Notice of Proposed Action (NoPA) to all interested parties at least 15 days before the sale and no one objects. Limited Authority requires the sale go to court for confirmation, where the judge hears the sale terms and accepts overbids in open court. The accepted sale price must be at least 90% of the appraised value set by the court-appointed Probate Referee under Probate Code 10309. The overbid increment at confirmation is calculated as 10% of the first $10,000 of the original bid plus 5% of the balance, with a minimum overbid of $500 in many counties' local rules. Knowing which authority you have changes everything about marketing strategy.
What IAEA is, and why it exists
Before 1988, almost every probate real-estate sale in California required a court confirmation hearing. Sales took six to twelve months, marketing was constrained by court-noticed bid procedures, and prices suffered because the process scared away financed buyers. The Legislature passed IAEA to streamline estate administration, codified in Probate Code Division 7 Part 6, Chapter 4 (sections 10400-10592). The Act lets qualified personal representatives act with court-approved independence, subject to notice and the right of beneficiaries to object.
Today, the great majority of California probate estates open with a petition that requests Full Authority. The court grants Full Authority unless an interested party objects, in which case the court may grant Limited Authority instead. Authority can also be modified later — a beneficiary can petition to revoke or limit IAEA powers if the personal representative is mismanaging the estate.
Understanding what authority the personal representative holds is the first question I ask on any probate listing call. The executor often doesn't know off the top of their head. The answer is on the Letters Testamentary or Letters of Administration — look for the box checked 'with full authority under the Independent Administration of Estates Act' versus 'with limited authority.'
Full Authority: what the executor can do without court
With Full Authority, the personal representative can list, market, accept an offer, open escrow, and close a sale on real property without ever filing a court petition for that sale. The two procedural requirements are: (1) get a Probate Referee's appraisal under Probate Code 8901 establishing the inventory value, and (2) send a Notice of Proposed Action under Probate Code 10580-10592 to every person entitled to notice at least 15 days before consummating the sale.
The NoPA describes the proposed action in enough detail that an interested party can decide whether to object. For a real-estate sale, that means buyer name, sale price, key terms (cash vs financed, contingencies, close date), and how the price relates to the Probate Referee's appraisal. Any person entitled to notice has 15 days from delivery to file a written objection. If no objection arrives, the sale proceeds. If an objection arrives, the personal representative can either renegotiate or take the sale to court for confirmation.
Full Authority dramatically improves marketing. The property can be listed in MLS like any standard transaction, written into a CAR Residential Purchase Agreement with a Probate Sale Addendum, and closed in 30 to 45 days. Financed buyers participate; cash discounts are smaller. I priced and sold a Big Sky estate this way last year — 12 days on market, multiple offers, 60-day NoPA-and-close, no court appearance.
Limited Authority: court confirmation required
Limited Authority means the personal representative can still negotiate a sale, but the sale is not final until the court confirms it at a public hearing. The personal representative files a Report of Sale and Petition for Order Confirming Sale of Real Property (Judicial Council form DE-260) under Probate Code 10300 et seq. The hearing is publicly noticed; anyone can show up and overbid.
At the confirmation hearing the court reviews the sale price against the Probate Referee's appraisal, confirms the sale meets the 90% minimum (Probate Code 10309), and then opens the floor for overbids. The minimum overbid is calculated under Probate Code 10311: 10% of the first $10,000 of the accepted bid plus 5% of the amount over $10,000. Most courts then round this up to the next $500 or $1,000 increment per local rule. Subsequent overbids during the hearing typically go in $5,000 or $10,000 increments at the judge's direction.
An overbidder must show up to court with a cashier's check for at least 10% of the proposed overbid amount, made out to the estate (check your county's local rules; Ventura County requires the 10% deposit in cashier's-check form payable to the estate, presented before the hearing begins). If they win, they sign a purchase agreement at the courthouse and close on the same terms as the original buyer, less the contingency period.
The 90% appraisal rule
Probate Code 10309 sets a floor: the court will not confirm a sale of real property at less than 90% of the Probate Referee's appraised value. This applies to court-confirmed sales (Limited Authority) and is also the practical standard for NoPA sales under Full Authority — a beneficiary objecting to a NoPA sale at less than 90% has a strong argument the personal representative is not protecting the estate.
The Probate Referee is appointed by the court under Probate Code 8920 and assigned by the county. In Ventura County, you don't pick your Probate Referee; you get the next one on the rotation. The Referee appraises the property based on date-of-death value (or a date of distribution value if appropriate) and files the appraisal as part of the estate inventory.
If the Referee's number is too low or too high compared to what current market data shows, the personal representative can request a re-appraisal, or in some cases substitute an independent appraisal with a Petition for Substituted Appraiser under Probate Code 8901. This is unusual but not rare. I've seen Referee appraisals that were $200,000 below current market because the Referee used stale comps; the executor's attorney petitioned for a fresh look.
The confirmation hearing and overbidding mechanics
Overbidding at a probate confirmation hearing is one of the few places in California real estate where you see live, courtroom auction dynamics. Worth knowing the mechanics whether you are buying or selling. The hearing is set on the court's probate calendar, usually 30 to 45 days after the petition is filed. Notice goes to all heirs and to the public via the court's published calendar.
On the day of the hearing, the personal representative and the original buyer typically appear (or their attorneys do). The court calls the case, reviews the petition, and asks if there are overbids. Anyone present can overbid if they meet the minimum increment and have the cashier's-check deposit ready. The original buyer usually has standing to overbid as well, and often does to protect their position.
Bidding continues until no one is willing to go higher. The court then confirms the sale to the high bidder, signs the order, and the parties sign a court-confirmation purchase contract. Escrow closes in 30 to 45 days. The original buyer who is overbid loses the property but is refunded their good-faith deposit. They are not reimbursed for inspection or appraisal costs they paid during the marketing period.
| Step | Timing | What happens |
|---|---|---|
| Probate opens | Day 1 | Petition filed, Letters issued with Full or Limited Authority |
| Referee appraisal | Day 30-60 | Court-assigned Probate Referee appraises real property |
| Listing + offer | Day 60-150 | MLS marketing; accepted offer at 90%+ of appraisal |
| Full Authority path | Day 150-180 | Notice of Proposed Action sent, 15-day objection window, close |
| Limited Authority path | Day 180-240 | Petition filed, hearing set, courtroom overbidding, close |
How buyers should approach an IAEA listing
If you're a buyer eyeing a probate listing, the first question to ask your agent is: 'Full or Limited Authority?' The MLS listing remarks usually say. If Full Authority, you can write an offer like any standard transaction with a Probate Sale Addendum (CAR form PA), expect a NoPA notice period, and close in 45 to 60 days. Inspection contingencies usually stay in, though sellers in probate often deliver the property strictly as-is.
If Limited Authority, write the offer knowing your purchase is subject to court confirmation. Your offer becomes the opening bid at the courtroom auction. Anyone can overbid you. Build in the cost of being outbid: inspections you pay for could be wasted. Many buyer agents recommend deferring expensive inspection work until after the confirmation hearing for Limited Authority sales, and instead doing a careful pre-offer walkthrough with a contractor.
Cash buyers do well at confirmation hearings. The court likes certainty, and other potential overbidders are often investors with cash. If you're financing, your loan needs to fit the standard probate-sale timeline (30 to 45 days from confirmation to close).
How sellers and executors should price
Pricing a probate listing is different from a standard sale. Two constraints: the 90% floor from the Probate Referee's appraisal, and the duty of the personal representative under Probate Code 9600 et seq. to manage the estate prudently for the benefit of heirs/beneficiaries. Underpricing exposes the personal representative to a surcharge action; overpricing wastes time and may force a price reduction that triggers heir objections.
I price probate listings using current closed comps in the same tract, adjusted for condition, plus the Probate Referee's value as a reference point. Where the comps and the Referee diverge significantly, I document why in writing to the executor and their attorney. The pricing decision is ultimately the personal representative's call, made with their attorney's input.
Common mistake: pricing at the Probate Referee's number and treating it as market value. The Referee's appraisal is for inventory and tax purposes, often as of date of death. Months later, when the home actually hits the market, the right price can be 5-15% different. Use the Referee's number as a floor, not a ceiling.
Common mistakes I see
Five mistakes that cost probate sellers real money. (1) Listing before Letters are issued. The personal representative has no authority to sign a listing agreement until the court issues Letters. Pre-Letters listings get challenged. (2) Skipping the NoPA on a Full Authority sale and hoping no heir notices. Heirs notice; the sale can be undone. (3) Treating the Probate Referee's appraisal as market value. It's a floor and a reference, not a list price.
(4) Accepting an offer that's less than 90% of appraisal in a Limited Authority case without first petitioning to revise the appraisal. The court won't confirm and you've burned 45 days. (5) Allowing the original buyer to walk into the confirmation hearing without a Buyer Acknowledgment of overbid procedures. Buyers who get blindsided by the overbid process can later claim they didn't understand and try to back out.
When I take a probate listing, the first packet I send the executor and their attorney is a checklist: Letters in hand, authority type confirmed, Probate Referee assigned, expected NoPA distribution list, and pricing rationale memo. That packet is the difference between a clean closing and a multi-month re-do.
Frequently Asked Questions
What does IAEA stand for?
Independent Administration of Estates Act, codified at California Probate Code sections 10400-10592. It lets qualified personal representatives administer an estate with less court supervision than the traditional process.
What is the difference between Full and Limited Authority?
Full Authority lets the personal representative sell real property without a court confirmation hearing, after a 15-day Notice of Proposed Action. Limited Authority requires court confirmation of any real-property sale, with public overbidding at the hearing.
What is a Notice of Proposed Action?
A written notice under Probate Code 10580-10592 that the personal representative sends to all interested parties (heirs, beneficiaries, others entitled to notice) at least 15 days before consummating a Full Authority sale. Recipients can object in writing within the 15 days.
What is the 90% rule?
California Probate Code 10309 prevents the court from confirming a sale at less than 90% of the Probate Referee's appraised value. It is also the practical standard for Full Authority NoPA sales.
How does overbidding work?
At the confirmation hearing, anyone can overbid the accepted sale price. The minimum first overbid under Probate Code 10311 is 10% of the first $10,000 of the accepted bid plus 5% of the amount over $10,000. Overbidders must bring a 10% cashier's check made out to the estate.
How long does an IAEA probate sale take?
Full Authority: typically 45 to 60 days from accepted offer to close, plus the 15-day NoPA window. Limited Authority: typically 90 to 150 days, depending on the court calendar.
Can a financed buyer participate in a probate sale?
Yes. Full Authority sales accept financed offers like any standard transaction. Limited Authority sales also accept financed offers, but the buyer must be ready to close 30 to 45 days after the confirmation hearing.
Who picks the Probate Referee?
The court does. Probate Referees are appointed under Probate Code 8920 by the State Controller and assigned to estates on a rotating basis within each county. You cannot select your own Referee.
