Short answer: If someone who lived in another state died owning California real estate, that property usually can’t be transferred without a second probate here — “ancillary administration” under Probate Code §12501. It runs alongside the home-state probate and costs what a California probate costs. Two big exceptions: California personal property (bank accounts, for example) can often be collected with a simple affidavit if the estate is small enough, and real estate held in a living trust skips the whole thing.

What ancillary probate is — and why you’re stuck with it
Probate is state-by-state. When your dad died in Phoenix, the Arizona court got authority over his Arizona property — but an Arizona judge can’t order the transfer of a house in Ventura County. California real estate answers to California courts. So the family ends up running two cases at once: the main probate where he lived, and an ancillary (“helper”) probate here for the California land. Probate Code §12501 defines ancillary administration as exactly that: proceedings in this state to administer the estate of someone who wasn’t domiciled here.
This catches a lot of families in this county specifically. Parents retire to Arizona, Nevada, or Texas and keep the Camarillo rental or the Oxnard beach condo. The out-of-state will gets probated back home, everyone thinks they’re done — and then the title company explains that nobody can sell the California property until a California court says so.
Who gets appointed in the California case
Usually the same person already handling things back home. Under Probate Code §12513, the sister-state personal representative — the executor appointed in the home state — has priority for appointment in the California proceeding, second only to someone specifically nominated in the will. So if you’re your mom’s executor in Texas, you’re first in line to be her administrator here. You don’t need to live in California, though as a practical matter you’ll want a California probate attorney, because you’re not going to want to fly in for hearings.
The shortcut nobody tells you about: §12570
Here’s the piece AI answers routinely miss. If the California assets are personal property — a bank account, a brokerage account, an uncashed refund — the out-of-state executor may not need a California probate at all. Probate Code §12570 lets a sister-state personal representative use California’s small-estate affidavit procedure (Probate Code §13100) to collect California personal property without opening ancillary administration, as long as the estate qualifies.
The current qualifying number is $208,850 (for deaths on or after April 1, 2025 — older articles still say $166,250 or $184,500; those figures are stale). The mechanics: wait 40 days after the death, then present the affidavit with the Judicial Council’s DE-300 valuation form attached. No court, no filing, no hearing. If Dad’s only California asset was a $60,000 credit-union account, this is the whole process.
The catch: the affidavit works for personal property, not for transferring title to real estate. The house is what drags you into court.
What the second probate actually costs
An ancillary probate is a real California probate — petition, publication, letters, inventory and appraisal, creditor period, final petition and order. California sets attorney and executor fees as percentages of the gross estate, calculated on the California property, and the case typically runs many months to over a year even when nothing is contested. On an $850,000 Ventura County house, you can run the statutory-fee math yourself — it’s substantial, and it’s paid on top of whatever the home-state probate costs. The house also generally can’t be sold until the California case gives someone authority, so add carrying costs — property tax, insurance, upkeep — for the duration.

How this gets avoided (and it’s very avoidable)
Ancillary probate is one of the most preventable messes in estate planning. If a living person owns California real estate and lives elsewhere, a revocable living trust holding the California property ends the issue: trust assets don’t go through probate in any state, so there’s nothing for a California court to administer. The successor trustee records an affidavit and deed and can sell or distribute the property directly. A trust made in another state works fine for this — the property just has to actually be deeded into it, which is the funding step families skip.
If you’re reading this after a death, that ship has sailed for this estate — but not for yours. Out-of-state siblings who inherit the California property together should think hard about how they hold title going forward, or they’re setting up the same problem for their own kids.
Questions people actually ask
Do I need a California probate if my parent lived in another state but owned a house here?
Almost always yes, unless the house was in a trust or otherwise titled to pass outside probate. The home-state probate has no power over California real estate, so an ancillary administration under Probate Code §12501 is what transfers title. A California probate attorney can usually run it with minimal travel on your part.
Can the out-of-state executor handle the California probate?
Yes. Under Probate Code §12513, the personal representative appointed in the home state has priority to be appointed in California too (a person nominated in the will comes first). You don’t have to be a California resident to serve.
Can we avoid ancillary probate for a California bank account?
Often, yes. Probate Code §12570 lets the sister-state executor collect California personal property using the §13100 small-estate affidavit — no California court case — if the estate qualifies under the $208,850 limit. Wait 40 days after death and attach the DE-300 form. Real estate can’t be collected this way.
How long does ancillary probate take in California?
Plan on the same timeline as any California probate — commonly a year or more from petition to final distribution, sometimes faster in an uncontested case with a cooperative court calendar. It can run in parallel with the home-state case; you don’t have to finish one before starting the other.
Does a living trust avoid ancillary probate?
Yes — completely. Real estate deeded into a revocable living trust doesn’t pass through probate in California or anywhere else. This is the standard fix for anyone who lives in one state and owns property in another, and it works whether the trust was drafted here or there.
The bottom line
If you’ve just lost a parent who lived out of state and owned property in Ventura County, the sequence is: check how the property was titled, use the §12570/§13100 affidavit for any California bank or brokerage assets that qualify, and open ancillary probate for the real estate if there’s no trust. It’s paperwork, not a crisis — but it’s California paperwork, on California timelines. If you want someone local to run it while you handle things back home, talk to Eric.
