What does probate actually cost in California?

California sets probate fees by statute, not by the hour, and the fee runs on the gross value of the estate. On a $1,000,000 estate, the schedule produces $23,000 for the executor and a separate $23,000 for the estate’s attorney, for $46,000 in ordinary fees before court costs or a bond (Prob. Code §§10800, 10810). That figure is usually larger than families expect, and it comes straight out of what the heirs would otherwise receive.

Does a living trust avoid probate automatically?

No. A trust only controls the assets that are actually retitled into its name. A house, bank account, or investment left in your own name is not protected by the trust and can still require court-supervised probate at death. Signing the trust and funding it are two different steps, and skipping the second one is one of the most common mistakes I see.

Can a beneficiary designation override my will or trust?

Yes. The beneficiary form you filled out when you opened a retirement account or life insurance policy controls who receives that asset, regardless of what your will or trust says. An account with a valid beneficiary designation pays that person directly and outside of probate, even when it contradicts the rest of your estate plan.

If you want a straight read on whether your existing plan has already made one of these mistakes, start with a trust health check.

The one thing

Most trusts fail for the same reason: improper funding. A trust that doesn’t hold your assets is a stack of paper. Most of the mistakes in this guide trace back to the same root: a plan that got signed, then never finished, never funded, or never updated.

• $46,000: combined statutory probate fees on a $1 million California estate (Prob. Code §§10800, 10810).
• 1 year: window to move in and claim the parent-child exclusion under Prop 19.
• 10 years: deadline to empty most inherited IRAs under the SECURE Act.
• $2,000: SSI asset limit that a direct inheritance blows through.

Mistake 1: The property tax bill that resets overnight

Under Prop 13, your property tax rides on the assessed value from when you bought, growing no more than 2% a year. For decades, children could inherit the house and keep that low assessment. Proposition 19 ended most of that on February 16, 2021. (Cal. Const., art. XIII A, §2.1; Rev. & Tax. Code, §63.2.)

The exclusion now covers a primary residence only, and only if the child moves in within one year and claims the homeowner’s exemption. Even then, the protection is capped at $1,044,586 over the old assessed value for transfers occurring February 16, 2025 through February 15, 2027; the Board of Equalization adjusts the figure every two years. Rentals and vacation homes get reassessed to full market value. No exceptions, no grace period.

An illustration. Your parents bought a Ventura house in 1985. The assessed value sits near $180,000 and the tax bill runs about $2,200 a year. The house is worth $1.1 million. If you inherit it as a rental, the county reassesses it at market value and the bill lands north of $11,000 a year. Miss the one-year move-in deadline on a primary residence and the same thing happens.

Sometimes the honest answer is that the reassessment can’t be avoided. But you should learn that number while your parents are alive, when the family can still decide what to do about it. Finding out from the assessor’s supplemental bill is the expensive way.

Mistake 2: The $3,000 trust that buys a $46,000 probate

A trust is like a bowl. You carry it around, you put things in and take things out as you please, and it has instructions for what happens after you’re gone. Here’s the catch: it only controls what’s actually in the bowl. Your house counts only if the deed puts it there. Your accounts count only if they’re retitled or pointed at the trust.

Clients hear this from me for the first time and the reaction is always the same: stunned. Nobody told them the trust was step one, and that funding it was the job. Plenty of attorneys skip that conversation too.

The failures follow a pattern. A refinance where the lender pulls the house out of the trust and nobody deeds it back. A new brokerage account opened in your own name. A business interest that was never assigned. Any of those assets sitting outside the trust above California’s small-estate threshold of $208,850 for deaths on or after April 1, 2025 sends your family to probate (Prob. Code, §13100; the threshold adjusts periodically).

On a $1 million estate, combined statutory fees for the attorney and the personal representative run $46,000, before costs, and probate commonly takes a year or more. (Prob. Code, §§10800, 10810.) There is a rescue: a petition under Probate Code section 850 asking the court to confirm the asset belongs to the trust. (Estate of Heggstad (1993) 16 Cal.App.4th 943; Ukkestad v. RBS Asset Finance, Inc. (2015) 235 Cal.App.4th 156.) It works when the paperwork supports it. It also costs thousands of dollars and months of waiting to fix what a recorded deed would have handled.

Mistake 3: One title change that costs six figures

California community property carries a tax advantage most states would envy: at the first spouse’s death, both halves of the property get a new income tax basis at market value, wiping out the built-in capital gain. (26 U.S.C. §1014(b)(6).) Hold that same property in joint tenancy and only the deceased spouse’s half steps up.

An illustration. A couple bought a rental in 1998 for $300,000; it’s worth $1.2 million at the first death. As community property, the survivor’s basis becomes $1.2 million and a sale produces little or no gain. As joint tenancy, the survivor keeps a $150,000 basis on their half and carries roughly $450,000 of built-in gain into the sale.

The trap is that title companies and lenders change how spouses hold title all the time, usually on a standard form, usually during a refinance. Changing the character of property between spouses requires an express written declaration signed by the spouse giving something up. (Fam. Code, §§760, 852.) A checkbox on a deed can undo a six-figure tax benefit.

Federal tax sits outside my core lane, so before you rely on any basis figure, run the numbers with your CPA. The planning move, holding title correctly in the first place, is squarely mine.

Mistake 4: The courtroom nobody plans to end up in

Estate planning gets sold as what happens when you die. The uglier risk is what happens if you don’t die: a stroke, a dementia diagnosis, a bad fall. If nobody holds a valid power of attorney and your assets aren’t in a trust with a successor trustee, the only path left is a court conservatorship.

A conservatorship is public, supervised, and expensive. A court investigator interviews you and reports to the judge (Prob. Code, §1826). The conservator posts a bond, files accountings on a court schedule (Prob. Code, §2620), and pays attorneys out of your estate at every step. If your children disagree about who should be in charge, that disagreement becomes litigation, and the estate funds both sides of it.

The prevention kit is short: a durable power of attorney (Prob. Code, §4000 et seq.), an advance health care directive (Prob. Code, §4600 et seq.), a HIPAA authorization, and a funded trust whose successor trustee can step in without asking a judge. These documents only work if you sign them while you still have capacity. Wait for the diagnosis and the option is often gone.

Mistake 5: The business with no instructions

If you own a business and die without succession instructions, ask one question: who signs payroll on Friday? If the answer is nobody, the business starts dying the same week you do. Vendors freeze, employees leave, and the family sells in a hurry at a discount.

The fixes are unglamorous and they work. Your ownership interest belongs in your trust, with an assignment that actually got signed. Your successor trustee needs authority to run or wind down the company. Co-owners need a buy-sell agreement that sets the price and the trigger before anyone is grieving. And licensed practices carry an extra wrinkle: California generally restricts who may own them, so the exit has to be planned, not improvised.

Valuations and federal estate tax questions belong with your CPA and me in the same conversation. What I won’t do is sell you a complicated structure you don’t need. Most family businesses need clear instructions, a named successor, and paperwork that matches reality.

Mistake 6: The gift that cancels the benefits

SSI and Medi-Cal are means-tested. For SSI, the resource limit is $2,000 for an individual. (42 U.S.C. §1382.) Leave $100,000 outright to a child on those benefits and you haven’t secured their future; you’ve disqualified them. The inheritance gets spent down replacing the benefits it cancelled, and the services that took years to arrange can be hard to get back.

The tool built for this is a third-party special needs trust: funded by you, controlled by a trustee you choose, and drafted so distributions supplement benefits instead of replacing them. Because it was never the beneficiary’s money, the state has no payback claim when they die. Compare the first-party version, funded with the beneficiary’s own assets, which must repay Medi-Cal from whatever remains. (42 U.S.C. §1396p(d)(4)(A).) An ABLE account (26 U.S.C. §529A) helps for smaller sums, but it has contribution and balance limits.

The order of operations decides everything. Draft the trust before the money moves. Once an inheritance lands in the beneficiary’s name, the remaining options are worse, slower, and end with a payback provision.

Mistake 7: The forms that outrank your will

Retirement accounts and life insurance don’t pass under your will or your trust. They pass by beneficiary designation, the form you filled out the day you opened the account and haven’t looked at since. If your ex-spouse is still on the form, your ex-spouse is in line for the money, and litigation to undo it is expensive and uncertain.

Name a minor child directly and the custodian won’t just hand a teenager the money; expect court involvement and a guardianship of the estate until age 18, followed by a lump sum to an eighteen-year-old. Name your estate and you may have converted a non-probate asset into a probate asset.

Taxes compound the problem. Since the SECURE Act, most non-spouse beneficiaries must empty an inherited IRA within 10 years, and California taxes those distributions as ordinary income. (Pub. L. No. 116-94 (2019); 26 U.S.C. §401(a)(9).) Naming a trust as beneficiary can be the right move, but only if the trust was drafted with retirement-specific language; a generic trust as beneficiary can accelerate the tax instead. This is federal tax territory, so the distribution plan gets built with your CPA.

The habit that prevents all of it costs nothing: reread every beneficiary form after every marriage, divorce, birth, and death.

What the plan is actually worth

Four moves, in order

1. Pull the paper. Gather the trust, will, powers of attorney, health care directive, deeds, and every beneficiary form. A document that doesn’t exist is a finding too; write it down.
2. Check every title. Read the deed: is the house in the trust’s name today? Go account by account: retitled to the trust, covered by a designation, or sitting in your own name headed for probate.
3. Check every beneficiary form. Retirement accounts, life insurance, annuities. Right people, no minors named outright, no ex-spouses, and contingent beneficiaries on every form.
4. Get the plan reviewed. Prop 19 (2021) and the SECURE Act (2020) rewrote the rules most older plans assumed. If your plan predates them, or predates your last marriage, divorce, birth, or death in the family, it needs a fresh read.

The deadlines that don’t wait

Prop 19 gives a child one year to move in and claim the exclusion; the clock starts at the parent’s death.

The SECURE Act’s 10-year distribution clock starts at death, whether or not anyone has read the form.

Incapacity documents must be signed while you have capacity. After the diagnosis, the courthouse may be the only door left.
