What Is Ancillary Probate in California?

By Grant A. Toeppen

Ancillary probate is a California court proceeding used to transfer California property left by someone who lived in another state or another country. When a person dies domiciled elsewhere but owned real estate or other assets in California, those California assets generally have to be administered under California law, in a California court — even though the main estate is being handled where the person actually lived.

Why a second proceeding is needed

Each state controls how title to real estate within its borders is transferred. So when someone who lived in, say, Arizona — or France — owned a home in California, the proceeding in their home state or country has no direct authority to clear the title to that California property. California needs its own proceeding to do that. That California proceeding is the "ancillary" (secondary) administration, running alongside or after the "primary" administration in the home jurisdiction.

When ancillary probate applies

It typically comes up when the deceased person:

Lived in another US state but owned a California home, rental, or other real property, or
Lived in another country but owned California real estate or significant California assets.

If the California property was held in a living trust, jointly with right of survivorship, or with a transfer-on-death deed, ancillary probate may be avoided — just as with any California estate. And if the California assets are modest, a small-estate procedure may apply instead of full ancillary administration. (See What Is Summary Probate in California?)

How it works

The process mirrors a regular California probate, with some welcome efficiencies when there's already a proceeding elsewhere:

Using the home-state appointment. If an executor has already been appointed in the decedent's home state, that appointment and the will can often be used to support the California ancillary proceeding, sometimes streamlining who is appointed here.
Admitting a foreign or out-of-state will. A will valid where it was made can frequently be admitted in California to govern the California property.
The usual California steps. Notice, an inventory and appraisal of the California assets, handling of California creditors, and a court order transferring or confirming the property.

A common scenario for international families

This is exactly the situation many of the families we help are in: a parent spent their later years abroad — or in another state — but kept a California home. The home can't simply be signed over from overseas; California needs its ancillary proceeding to clear title. Coordinating that California proceeding with the administration in the home country or state is a core part of cross-border estate work, and it can be handled remotely. (See My Parent Died in California and I Live Overseas.)

If a relative who lived elsewhere left property in California, we can open and handle the California ancillary proceeding from here and coordinate it with the estate in their home state or country. Request a consultation.

Frequently Asked Questions

What is ancillary probate? It's a secondary California court proceeding used to transfer California property left by someone who lived (was domiciled) in another state or country, while the main estate is handled where they lived.

When is ancillary probate required in California? Generally when a non-California resident dies owning California real estate or significant California assets that aren't covered by a trust, survivorship title, or a transfer-on-death deed.

Can a will from another state or country be used? Often, yes. A will valid where it was made can frequently be admitted in California to govern the California property in an ancillary proceeding.

Can ancillary probate be avoided? Sometimes — if the California property was in a living trust, held in joint tenancy, or covered by a transfer-on-death deed, or if a small-estate procedure applies.

Can ancillary probate be handled remotely? Yes. Like other California probate, it runs on filings and attorney court appearances, so an out-of-state or overseas representative can manage it without traveling here.
