How to Make a Will in California: What Families Need to Know
What Happened
A California estate planning law firm published a comprehensive guide to will execution requirements in California, walking readers through the formal legal steps required to create a recognized will under state law. The guide covers witness requirements, the role of notarization, holographic wills, what a will should contain, and how wills interact with the probate process. The article draws directly on California Probate Code provisions governing will execution, interested witnesses, and the duty to lodge a will with the court after death.
The guide addresses one of the most persistent misconceptions in California estate planning: that notarization validates a will. It does not. California law requires 2Cal. Prob. Code § 6110Verified Oct 18, 2026View source witnesses who observe the signing and then sign the document themselves. California does not require notarization for wills, and a document signed only before a notary — without witnesses — fails to meet execution requirements under state law. The guide notes that this misunderstanding leads families to believe their documents are in order when they may not be.
The article also clarifies the relationship between wills and probate, emphasizing that a will does not bypass the court process. It explains California's small estate thresholds, the role of a pour-over will alongside a revocable living trust, and the practical steps involved in signing, storing, and updating a will after major life changes. The piece targets California residents who either lack a will entirely or hold documents that may not meet current execution requirements.
What It Means
Execution Requirements and Common Mistakes
California's will execution rules are specific, and errors at the signing table create problems that surface years later during probate. A formal, typed will requires the testator to be at least 18 yearsCal. Prob. Code § 6110Verified Oct 18, 2026View source old, of sound mind, and to sign in the presence of 2Cal. Prob. Code § 6110Verified Oct 18, 2026View source witnesses simultaneously. Both witnesses must understand the document is a will and must sign it during the testator's lifetime. A will that fails these requirements faces a difficult path to admission — the person offering it must prove by clear and convincing evidence that the decedent intended it as a will, which is a contested court proceeding most families cannot afford.
Witness selection matters as much as witness count. California law does not automatically invalidate a will because a beneficiary served as a witness, but it creates a rebuttable presumption of undue influence against that witness's gift. An interested witness may serve, but their bequest faces a presumption of undue influence unless two other disinterested witnesses also signed. The practical outcome: the interested witness may receive nothing more than their intestate share. Families who name a spouse, child, or executor-beneficiary as a witness often discover this problem only after the testator has died, when it is too late to correct.
Holographic Wills and What They Cannot Do
California recognizes handwritten wills, requiring no witnesses, provided the signature and all material provisions appear in the testator's own handwriting and testamentary intent is clear. While holographic wills carry legal recognition, they generate a disproportionate share of estate litigation. Ambiguous language, missing executor nominations, absent alternate beneficiaries, and undated documents that conflict with other instruments all create disputes that drain estate assets and delay distribution. The guide correctly characterizes holographic wills as emergency measures rather than estate plans.
A will — whether typed or handwritten — does not avoid probate. California's small estate affidavit procedure allows successors to collect personal property without court involvement when the gross value of the decedent's California real and personal property stays at or below $208,850Cal. Prob. Code § 13100Verified Sep 8, 2026View source, after a waiting period of 40 daysCal. Prob. Code § 13100Verified Sep 8, 2026View source following death. A separate procedure applies to real property valued at or below $69,625Cal. Prob. Code § 13100Verified Sep 8, 2026View source. Estates above those thresholds enter formal probate regardless of whether a will exists. California's probate timeline runs 12 months to 18 months on average, and attorney fees follow a statutory schedule — statutory (set by law)Cal. Prob. Code § 10810Verified Sep 8, 2026View source — calculated on the gross estate value without reduction for mortgages or other encumbrances. On a $500,000 estate, combined attorney and executor fees reach approximately $27,235Cal. Prob. Code § 10810Verified Sep 8, 2026View source. Families who want to keep assets out of that process generally pair a funded revocable living trust with a pour-over will.

What a Complete Will Covers — and What It Cannot Control
A will that actually functions covers several categories beyond asset distribution. An executor nomination — with at least one named alternate — gives the probate court a clear starting point for appointment. A guardian nomination for minor children carries particular weight in California: a parent's nominee receives appointment priority, though the court retains authority to decline the nomination on a best-interest finding. A residuary clause captures assets not specifically listed, preventing partial intestacy. Clear alternate beneficiary designations address the common scenario where a named beneficiary predeceases the testator. California requires a surety bond for executors, though a will provision waiving the bond — or a written waiver from all beneficiaries — removes that requirement and eliminates the associated cost.
A will has no authority over assets that pass outside the probate estate. Life insurance proceeds, retirement accounts, payable-on-death bank accounts, transfer-on-death brokerage accounts, and property held in joint tenancy all transfer by designation or survivorship, regardless of what the will directs. California is a community property state, which means the surviving spouse already owns half of all community property acquired during the marriage — the decedent's will controls only the decedent's half. Coordinating beneficiary designations, account titles, and trust funding with the will's instructions prevents the common outcome where careful will drafting fails because the assets it was meant to govern never reach the probate estate. Explore our estate inventory checklist to identify which assets fall inside and outside a will's reach. Families navigating these decisions can also review the differences between standard wills and pour-over wills to understand how the two documents work together.
Storage, Revocation, and Life-Change Triggers
Execution errors are the most common source of will disputes, but storage failures run a close second. California law requires whoever holds the original will to lodge it with the Superior Court within 30 days of learning of the testator's death. A will stored in a safe deposit box that no one can access immediately after death creates a logistical problem at an already difficult moment. Naming the executor and telling that person exactly where the original will is located — and ensuring access — forms a necessary part of any complete plan.
Revocation requires deliberate action. A later will or codicil revokes an earlier one to the extent of conflict. Physical destruction — burning, tearing, canceling — with intent to revoke also terminates the document. Marriage after execution creates an omitted spouse claim under California law that can disrupt a carefully arranged distribution scheme. Divorce, births, deaths of named beneficiaries, significant asset acquisitions, and moves from another state all warrant a review. An out-of-state will generally carries recognition in California if it met the execution requirements of California law, the law of the state where it was signed, or the law of the testator's domicile at the time of execution — but a review after relocating confirms the document still reflects current intentions and assets.
Context from SimplyTrust
California families evaluating whether a will alone meets their planning needs can use SimplyTrust's free Probate Cost Calculator to estimate what formal probate would cost based on their estate's gross value. The calculator applies California's statutory fee schedule and produces a concrete figure that helps families weigh the cost of probate against the cost of establishing a trust. For families already working through an estate, the Executor Checklist walks through each step of the administration process, from lodging the will with the court to obtaining the inventory and appraisal and filing for final distribution.
Understanding what a will can and cannot accomplish sits at the center of any sound estate plan. A will provides instructions to a probate court and nominates guardians for children — functions no other document performs. But it does not avoid court, does not manage assets during incapacity, and does not control property that passes by designation or survivorship. Families who want both the flexibility of a will and the probate-avoidance benefits of a trust can explore how those documents work together through SimplyTrust's Trusts vs. Wills guide.
