If you die without a will in California, a probate judge distributes your estate under the state's intestate succession rules — Prob. Code §§21100–21140 — not your wishes. That means a spouse may receive far less than expected, an unmarried partner receives nothing regardless of how long you were together, and a court decides who raises your minor children. None of that reflects what you would have chosen.
A valid California will costs almost nothing to prepare yourself. It locks in your intentions, names the people you trust, and gives your family a clear roadmap instead of a court fight. Anyone 18 or older with any assets — a car, a bank account, a laptop, a retirement account you haven't updated — should have a will in place. Waiting until circumstances feel "serious enough" is exactly when it's too late.
What a Will Can (and Cannot) Do
Understanding the limits of a will prevents costly surprises.
A California will can:
- Name an executor (personal representative) to manage and distribute your estate
- Direct who receives your property and personal belongings
- Name a guardian for minor children if both parents die
- Disinherit an heir by name
- Designate a caretaker for a pet
A California will cannot:
- Transfer assets held in joint tenancy (they pass automatically to the surviving joint tenant)
- Distribute assets in a living trust (the trust controls those)
- Override beneficiary designations on life insurance, IRAs, 401(k)s, or TOD accounts
- Transfer assets already titled solely to another person
The most common trap: A person writes a will leaving "the house" to their child — but the house was transferred into a living trust years earlier. The will has no legal effect on trust assets. If you have a trust, review which assets are actually held in it before drafting will provisions.
Two Types of Valid California Wills
1. Holographic Will (Prob. Code §6111)
A holographic will is entirely handwritten by the person making it — every material provision, the date, and the signature must be in the testator's own handwriting. No witnesses are required under §6111(a).
The danger: printed will forms with handwritten fill-in sections almost always fail §6111. Any pre-printed text on the page can invalidate the entire document under California case law. If you go this route, every word must be written by hand on a blank page.
Courts can interpret handwritten portions to fill ambiguities under §6111(b), but ambiguity almost always means litigation. A holographic will is best used as a temporary emergency measure only. A properly executed witnessed will is always the better option.
2. Witnessed Will (Prob. Code §6110)
A witnessed will is the standard form used by most Californians. The requirements under §6110 are:
- In writing — typed is fine
- Signed by the testator — or by someone else at the testator's direction and in their presence
- Two witnesses — both present at the same time, signing within a reasonable time after witnessing the testator's signature (§6110(c))
Critical rule on witnesses: Witnesses should not be named beneficiaries. If a witness is also a beneficiary, that bequest is subject to a presumption of undue influence under Prob. Code §21350 and can be voided — unless two additional disinterested witnesses sign confirming the bequest was freely made.
Notarization is not required for a California will to be valid. Notarization is optional, but it adds "self-proving" status under §8220, which speeds up probate admission because the court can accept the will without tracking down witnesses to testify.
Who Can Make a Will in California
Under Prob. Code §6100, anyone who is:
- 18 years of age or older, OR
- Under 18 but lawfully married or in a registered domestic partnership
must also have testamentary capacity (§6100.5): you must understand (1) that you are making a will, (2) the nature and extent of your property, (3) who your natural heirs are, and (4) how the will distributes your estate.
A will signed during incapacity is void. If there is any concern about capacity at the time of signing — illness, medication, cognitive decline — document the circumstances with contemporaneous witness statements and, when possible, a written capacity assessment from a physician.
Step-by-Step: Writing a Valid Witnessed Will in California
Step 1 — Inventory Your Estate
List everything you own: real property (address + how it is vested), bank and brokerage accounts, vehicles, valuable personal property, and digital assets. California law under §872 recognizes the transfer of digital assets, so include login credentials, cryptocurrency, and online accounts with instructions for access.
Identify what will bypass the will entirely — IRAs, 401(k)s, life insurance with named beneficiaries, TOD/POD accounts, and jointly titled property. Those assets pass outside probate regardless of what the will says. Your will only controls what is titled in your name alone at death.
Step 2 — Identify Your Beneficiaries
Use full legal names. Identify each person's relationship to you and include contingent beneficiaries in case a primary predeceases you. Without a contingent, that share passes as if no will existed.
Always include a residuary clause: "I give the rest and residue of my estate, real and personal, wherever located, to [NAME]." This clause catches everything not specifically named and prevents partial intestacy.
Step 3 — Name an Executor (Personal Representative)
Your executor manages the estate: files the will with probate court, notifies creditors, marshals assets, and distributes the estate. Under Prob. Code §8402, an executor must be at least 18 years old and either a California resident or a relative of the decedent regardless of state of residence.
Always name a successor executor in case your first choice cannot or will not serve. An executor is entitled to statutory compensation under §10800 (the same 4%/3%/2% scale that applies to attorney fees), but can waive it in the will or at the time of service.
Step 4 — Name a Guardian for Minor Children
If both parents die, the nominated guardian raises your children. Courts apply the best interest of the child standard under §1514 before approving any guardian — but a nomination in a will carries significant weight and is the starting point for the court's analysis. Name a successor guardian as well in case your first choice is unavailable.
Step 5 — Draft the Will Document
Type the full text. The document must include:
- A declaration that this is your will and revokes all prior wills and codicils
- Your full legal name and county of residence
- Specific bequests (named items or amounts to named people)
- A residuary clause
- Executor nomination and successor executor
- Guardian nomination and successor guardian (if you have minor children)
- Your signature line and the date of signing
Step 6 — Sign in Front of Two Witnesses
All three parties — you and both witnesses — must be present at the same time. You sign first (or direct another to sign in your presence). The witnesses then sign, ideally including their printed names and addresses.
Witnesses must not be named beneficiaries in the will. Choose neighbors, coworkers, or friends with no financial interest in your estate.
Step 7 — Store the Original Safely
California has no statewide will registry. Options for storage:
- Safe deposit box — list someone authorized to access it on death
- Fireproof home safe — tell the executor the combination or location
- With the executor — hand them the original with written confirmation of its existence
California Superior Courts will not accept a will for safekeeping during your lifetime. The most important step: tell your executor exactly where the original is. Under §6124, a will that cannot be produced at death is presumed to have been revoked with intent. A will that no one can find is a will that does not exist.
Preparing a will in California requires precise language, proper execution, and a clear asset inventory — and mistakes can void specific provisions or trigger litigation.

Updating and Revoking a Will
A will is not a static document. Life events require updates.
Codicil: A written amendment to an existing will. Must be signed and witnessed with the same formalities as the original will under §6104. For significant changes, a new complete will is cleaner and reduces ambiguity.
Revocation: Under §6120, a will is revoked by (1) physically destroying the original and all copies with intent to revoke, or (2) a new will that expressly revokes the prior one.
Marriage after the will is signed: An omitted spouse is entitled to an intestate share of the estate under §21610 unless the will expressly names them. Update the will immediately after marriage.
Divorce: Under §6122, gifts to an ex-spouse and any nomination of the ex-spouse as executor or guardian are automatically revoked when the divorce is final. But this is litigation bait — update the will after divorce rather than relying on automatic revocation, and name replacement beneficiaries explicitly.
Birth of a child after the will: An omitted child is entitled to an intestate share under §21620 unless the will provides for them or expressly disinherits them. Update immediately after each birth.
When a Will Goes Through Probate
A will does not avoid probate. It tells the court what to do during probate — that is all. Any asset titled solely in the decedent's name with no surviving joint tenant and no beneficiary designation will go through the full probate process regardless of whether a will exists.
If avoiding probate is the goal, the solution is a living trust combined with asset re-titling — not a will alone. See our comparison guide at California Living Trust vs. Will (coming soon) for a complete side-by-side analysis.
6 Common Mistakes to Avoid
1. Using a printed form for a holographic will. Any pre-printed text on the page can invalidate a §6111 holographic will under California case law. If handwriting a will, start with a completely blank page and write every word by hand.
2. Naming a witness who is also a beneficiary. This triggers the §21350 presumption of undue influence. The bequest to that witness can be voided entirely — even if the intent was completely genuine.
3. Failing to update after marriage, divorce, or birth. California has statutory correction rules, but they are complex and frequently litigated. A current, clearly written will is always safer than relying on a statutory fix.
4. Leaving the original unfindable. A will that is not produced at death is presumed revoked under §6124. An original no one can locate is legally the same as no will at all.
5. Naming only one beneficiary with no contingent. If your sole beneficiary predeceases you, that asset passes intestate — to whomever the court decides, not to whom you would have chosen.
6. Assuming a will avoids probate. It does not. Only a funded living trust combined with proper asset titling avoids the probate process. A will is an instruction set for the probate court, not a bypass around it.
