How Does Estate Planning Work in California?

Probate on a $500,000 estate in California costs an estimated $27,235 and takes 9 months to 12 months for a simple estate, with attorney fees set by statute as a percentage of the gross estate. Estates under $208,850 can use a small-estate procedure instead.

A simple estate in California typically takes 9 months to 12 months through probate, and an average estate 12 months to 18 months; a contested one runs longer. The creditor claim period of 4 months is the floor. A funded revocable trust avoids probate entirely.

California has not adopted the Uniform Trust Code and does not require witnesses for trust execution. Notarization is not required for validity, though many financial institutions require notarized trust documents. The successor trustee can publish California's optional creditor notice to shorten the claim window to 4 months; without it, the settlor's creditors have up to 12 months to bring a claim.

A healthcare power of attorney in California requires 2 witnesses or notarization to be valid. A financial power of attorney requires 2 witnesses or notarization. A financial power of attorney is not durable by default; it must include durability language to survive incapacity.

In California, the executor files an inventory of the estate's assets within 120 days of appointment. A revocable trust skips the court-supervised inventory, so a trustee distributes without filing one.

In California, divorce automatically revokes a beneficiary designation that names a former spouse on the covered accounts, so the asset does not pass to the ex-spouse unless the designation is renewed after the divorce.

Estate Planning in California

Estate planning in California is shaped by statutory probate fees and community-property rules. The choice between a will and a revocable trust depends on which of those features changes the cost or process for your situation, not on any single rule.

A will goes through probate, with attorney fees set by statute as a percentage of the gross estate. A simple estate typically closes in 9 months to 12 months, and the 4 months creditor-claim window sets the floor. Estates under $208,850 can use the Small Estate Affidavit and avoid full probate administration. California sets a separate limit of $69,625 for real property. The Small Estate Affidavit is presented directly to the bank, employer, or other holder of the property — it is not filed with a court.

For a revocable trust, California does not require witnesses for trust execution. Notarization isn't required for validity, though banks and title companies typically expect a notarized trust before they'll work with it. California has not adopted the Uniform Trust Code; trust administration follows the state's own rules, which can affect trustee duties and beneficiary remedies.

California offers transfer-on-death deeds, which move real estate to a named beneficiary at death without probate. Combined with beneficiary designations on retirement accounts and payable-on-death registrations, these can move significant value outside probate without setting up a trust.
