Estate Planning in California: The Complete Guide

Published June 30, 2026 6 min read

Quick answer

Estate planning in California means putting a few documents in place — a will, a power of attorney, an advance health care directive, and (for most homeowners) a living trust — so the people you love aren't left to California's courts and intestacy rules. The one thing that makes California different from most states: probate here is unusually expensive because fees are set by statute and calculated on the gross value of your estate. That's why a living trust is worth it for most California homeowners, even though renters and modest estates are usually fine with just a will. This guide walks through every piece and links to the detailed California breakdowns.

Educational guide — not legal advice. California law is set by statute and changes over time. Consult a licensed California attorney about your specific situation.

Why California is different

Estate planning is broadly the same everywhere — you decide who gets your assets and who makes decisions if you can’t. But California has one feature that changes the advice: probate here is expensive.

California sets probate fees by statute (Probate Code §§10800, 10810), lets both the attorney and executor charge the schedule, and calculates the fee on the gross value of your estate — before subtracting your mortgage. The result is that a single California home can trigger tens of thousands of dollars in probate fees. That’s why so much California estate planning centers on avoiding probate with a living trust — a step that’s overkill in many other states but genuinely pays off here.

If you read nothing else: California homeowners usually benefit from a living trust; California renters usually don’t. Everything below explains why.

The core documents

A complete California estate plan is a short list. Here’s what each piece does.

1. A will

Your will names who inherits, who serves as executor, and — critically — who serves as guardian for minor children. A will is the only document that names guardians, so every parent of young kids needs one even if they also have a trust.

In California, a valid will must be in writing, signed, and witnessed by two people present at the same time (Probate Code §6110). It does not need to be notarized — a common and dangerous misconception. See Does a Will Have to Be Notarized in California?.

A basic California will runs $400–$1,200 from an attorney, or $0–$300 online for simple cases. See How Much Does a Will Cost in California in 2026?.

2. A revocable living trust (for most homeowners)

A living trust is a container you transfer your assets into while alive. You control it completely, and at death your successor trustee distributes the assets without probate. In California, this is the workhorse document for anyone who owns a home, because it sidesteps the statutory probate fees described above.

A trust package runs $2,000–$4,000 in California. Whether you need one is the central California question — see Do You Need a Living Trust in California? and the head-to-head in Will vs. Living Trust: Which Is Better in California?.

The one rule that matters most: a trust only avoids probate for assets actually retitled into it. An unfunded trust protects nothing. Fund it.

3. A durable financial power of attorney

Names someone to manage your money if you become incapacitated. Without it, your family may need a court conservatorship — slow and expensive. This document needs notarization in California.

4. An advance health care directive

California’s combined living will + healthcare proxy (Probate Code §4700). It states your wishes for end-of-life care and names someone to make medical decisions if you can’t. Pair it with a HIPAA authorization so your agent can access your records.

5. Beneficiary designations

Often overlooked, but they override your will. Retirement accounts, life insurance, and payable-on-death/transfer-on-death accounts pass directly to named beneficiaries and skip probate automatically. Keeping these current is some of the cheapest, highest-value estate planning you can do.

What happens if you do nothing

If you die without a will in California, the state’s intestacy rules (Probate Code §6400 et seq.) decide who inherits — and the answer may not be what you’d choose, especially for blended families or unmarried partners (who inherit nothing under intestacy). California’s community property rules also shape the outcome between spouses. The estate still goes through probate, just without your input.

Probate in California: cost and time

Because avoiding probate is the central California goal, it helps to know what you’re avoiding:

California also offers a small-estate affidavit for estates under $208,850 (rising to $239,700 in April 2026) — but most homeowners exceed that because the home counts at full value.

A simple sequence to get started

  1. Inventory what you own and roughly what it’s worth (count your home at full market value).
  2. Update beneficiary designations on retirement accounts and life insurance — free and immediate.
  3. Decide will-only vs. trust using the homeowner test above.
  4. Get the core documents — will, financial POA, advance health care directive (plus a trust if you own a home).
  5. Fund the trust if you set one up — retitle the home and accounts.
  6. Name guardians for minor children in your will.
  7. Tell your executor/trustee where everything is and review every few years or after a big life change.

The honest takeaway

California estate planning comes down to one fork in the road: do you own a home here? If yes, budget for a funded living trust — it almost always beats California’s statutory probate fees. If you rent or have modest assets, a simple will plus a power of attorney and a health care directive is a complete, responsible plan. Either way, keep your beneficiary designations current and tell someone where the documents are. Don’t let a seminar scare or upsell you — the right plan follows from your own numbers.

Common questions

Does California have an estate or inheritance tax?

No. California has neither a state estate tax nor an inheritance tax. Only the federal estate tax applies, and it affects only very large estates (the exemption is in the millions per person). For nearly all California families, the planning concern is probate cost, not death taxes.

Do unmarried partners inherit anything in California?

Under California’s intestacy rules, an unmarried partner who isn’t a registered domestic partner inherits nothing automatically, no matter how long the relationship. If you want a partner to inherit, you must name them in a will, trust, or beneficiary designation. Registered domestic partners are treated like spouses.

How does community property affect my estate plan?

California is a community property state: most assets acquired during marriage are owned 50/50. You can generally only give away your half of community property by will or trust; your spouse already owns the other half. Community property also gets a favorable double step-up in cost basis at the first spouse’s death, which is worth planning around.

Can I write my own will in California?

Yes. California recognizes holographic (handwritten) wills, a free statutory will form, and online will services — all valid if executed correctly. The key requirement for a typed will is two witnesses (notarization isn’t required). See Does a Will Have to Be Notarized in California?.

What’s the single most important step for a California homeowner?

Decide whether a funded living trust makes sense — and if you set one up, actually retitle your home into it. The most expensive mistake in California estate planning is owning a home in your personal name with no probate-avoidance plan, which can cost your heirs tens of thousands in statutory fees.
