The short answer
California differs from most states on the arithmetic: its probate fees are set by statute on the gross value of the estate, and a California home commonly puts an estate over the small-estate threshold.
Here are the documented thresholds:
- You probably need a living trust if you own a home (or any real estate) in California, or your total estate is comfortably above the small-estate threshold.
- You probably don’t if you rent, your assets are modest, or your major accounts already pass to named beneficiaries.
Let’s make that concrete.
The number that decides it: California’s small-estate threshold
California lets smaller estates skip formal probate using a simplified affidavit procedure (California Probate Code §13100). The threshold:
- Cal. Prob. Code §13100 states the small-estate affidavit ceiling as $166,250 “as adjusted periodically in accordance with Section 890”; §890(c) puts the adjusted list with the Judicial Council, whose published list (form DE-300) gives $208,850 for deaths on or after April 1, 2025.
Cal. Prob. Code §890 adjusts the amounts every three years — April 1, 2022, April 1, 2025, and next April 1, 2028 — and §890(c) puts the adjusted list with the Judicial Council. The Judicial Council’s published list (form DE-300) gives $208,850 for deaths on or after April 1, 2025 and states that these values will next be adjusted April 1, 2028.
If your estate is under that number, your heirs can often avoid full probate without a trust. If it’s over, a will sends the estate into formal probate — and in California, that’s costly.
California counts the gross value of assets under §§10800(a) and 10810(a), and a home is counted at its full market value, not its equity. A $600,000 home with a $450,000 mortgage counts as $600,000 — well over the threshold. So owning almost any California home puts the estate over the threshold at which formal probate applies.
Why probate is the thing you’re avoiding
California sets probate compensation by statute — §10800(a) for the personal representative and §10810(a) for the attorney — and each takes a percentage of the gross estate. On a $700,000 estate, that’s roughly $34,000 in combined statutory fees — plus court costs (~$435 per petition), a probate referee (~0.1% of appraised value), and 9–18 months of waiting.
A revocable living trust operates on the assets retitled into it, which are not part of the estate those schedules are computed on. What it costs to draft is quoted by the preparer. We found no independent published source for that figure as of September 2026; the ranges that are published come from law firms, from online document sellers, or from sites paid to refer customers to them, so none is cited here. For the statutory figures, see Probate Cost in California and the side-by-side in Will vs. Living Trust: Which Is Better in California?.
What the California thresholds turn on
1. Do you own real estate in California? → Yes: California computes statutory probate compensation on the home’s full appraised value, before the mortgage. See “What a trust gets you.” → No: continue.
2. Is the total estate above the §13100 small-estate ceiling, counting all assets at full value? → Yes: the estate exceeds the small-estate affidavit threshold, so formal administration and the statutory fee scale apply. → No: the estate is within the affidavit ceiling, and the §13100 procedure is available for the assets it covers.
3. Do your major assets already pass outside probate (retirement accounts and life insurance with named beneficiaries, payable-on-death/transfer-on-death accounts, jointly held property)? → Yes, mostly: little of the estate reaches the probate court, so little of it reaches the §10800 and §10810 fee base. A will directs what is left. → No: the assets that pass by will are in that fee base.
What a living trust actually gets you in California
- No probate on the trust assets — the single biggest financial win here.
- Privacy. Probate is a public court record; a trust is private.
- Incapacity protection. If you become incapacitated, your successor trustee manages the trust assets without a court conservatorship. A will does nothing while you’re alive; a trust does.
- Speed. Trust assets are distributed on the trust’s own terms, while a probate estate is distributed after the statutory steps, chiefly the creditor-claim period, are complete.
- No ancillary probate if you own property in another state too.
When you genuinely don’t need one
Be skeptical of the upsell if:
- You rent and own no real estate.
- Your estate is under the small-estate threshold.
- Your accounts already name beneficiaries and your home (if any) is jointly owned with right of survivorship.
- Your main goal is naming guardians for young children — that’s a job for a will, not a trust.
In these cases the documented instruments are a will, a power of attorney and an advance health care directive. What a trust costs to draft is quoted by the preparer and no independent source for it is cited.
A lower-cost middle path: TOD deeds and beneficiary designations
You don’t always need a full trust to avoid probate on specific assets. California offers tools that skip probate item-by-item:
- Revocable Transfer on Death Deed (RTODD) for residential real estate (Probate Code §5600 et seq.) — names a beneficiary who takes the described property at the transferor’s death, outside probate. The deed operates only on the property it describes, has no effect during incapacity, and where it names several beneficiaries they take as co-owners. Scheduled repeal: §5600(c) provides that Part 4 “shall remain in effect only until January 1, 2032, and as of that date is repealed, unless a later enacted statute, that is enacted before January 1, 2032, deletes or extends that date”, and that the repeal “shall not affect the validity or effect of a revocable transfer on death deed that is executed before January 1, 2032”. The January 1, 2032 date was set by SB 315 (Stats. 2021, ch. 215); the published text carries no later extension as of 2026-09-21.
- Payable-on-death (POD) bank accounts and transfer-on-death (TOD) brokerage registrations.
- Named beneficiaries on retirement accounts and life insurance.
For a single-home, simple-heir situation, a TOD deed plus beneficiary designations can avoid probate for far less than a trust. For multiple properties, blended families, incapacity planning, or anything complex, the trust is cleaner. See How to Avoid Probate in California for the full menu.
The catch with any trust: you have to fund it
A trust only avoids probate for assets actually titled in the trust’s name. The most common and costly mistake is paying for a trust and never retitling the house into it — which leaves the home in your personal name and headed straight for probate anyway. If you set up a California trust, confirm the attorney handles funding, or follow a funding checklist yourself.
What the record shows
California sets statutory probate compensation on the gross value of the estate, before deduction of encumbrances (Cal. Prob. Code §§10800 and 10810), so a mortgaged home is counted at its full value. A funded revocable trust removes the assets retitled into it from that calculation. The documented trade is the trust’s setup cost, cited above, against the statutory fee that would otherwise be computed on those assets — and a trust operates only on assets actually retitled into it. Assets already passing by beneficiary designation or survivorship are outside both the probate estate and the trust.
Common questions
Do I need a living trust in California if I have a will?
If you own a home, usually yes. A will alone sends your estate through California’s expensive statutory probate; a funded trust avoids it. A will and a trust do different jobs — the will names guardians for kids and catches stray assets, while the trust keeps your major assets out of probate. Most California homeowners end up with both.
At what estate size does a trust change the probate cost?
Real property is the common trigger, because the Cal. Prob. Code §§10800(a) and 10810(a) schedules count a home at its appraised value and pushes most owners past the $208,850 small-estate threshold (the figure for deaths on or after April 1, 2025; next adjusted April 1, 2028). If your total estate is under that threshold, your heirs can often use a simplified affidavit and a trust isn’t necessary.
Can’t I just add my kids to the deed instead of a trust?
Adding a child to your deed is a common DIY move that often backfires — it can trigger gift-tax reporting, expose the home to your child’s creditors or divorce, and forfeit a step-up in cost basis that saves capital-gains tax. A transfer on death deed or a trust usually accomplishes the goal more safely.
Does a living trust avoid the California estate tax?
There is no California estate or inheritance tax, so there’s nothing to avoid at the state level. A trust’s value here is avoiding probate, not taxes. Only very large estates face the federal estate tax, and a basic revocable trust doesn’t reduce that.
What happens to my trust if I move out of California?
A revocable living trust generally travels with you, though funding rules, spousal-property rules and document formalities vary between states. If you move into California with an out-of-state trust, the same review is wise.
