To write a will in California, put your wishes in writing, sign the document yourself, and have two competent adults witness your signature and sign the will themselves during your lifetime. You must be at least 18 and of sound mind when you sign.1California Legislative Information. California Probate Code 6100 Miss any of those pieces and a court can throw the whole document out, sending your property to relatives chosen by the state’s default rules instead of the people you named.
The Legal Requirements for a Valid Will
California law is specific about how a will has to be executed. Oral wills carry no weight. The document must be in writing, signed by you, or signed by someone else in your presence and at your direction if you can’t physically sign.2California Legislative Information. California Probate Code 6110
Two witnesses then need to sign the will during your lifetime. Both must be present at the same time, must see you sign or hear you acknowledge your signature, and must understand they are signing your will.2California Legislative Information. California Probate Code 6110 They don’t have to read it or know what’s inside.
There is a safety net for execution flaws. A court can still admit a will with a technical defect if someone proves by clear and convincing evidence that you intended the document to be your will when you signed it.2California Legislative Information. California Probate Code 6110 Better not to need it. Proving intent in court means litigation your family shouldn’t have to fight.
Pick Witnesses Who Don’t Inherit
A witness who also inherits under the will doesn’t invalidate the document, but they create a problem for themselves. If fewer than two other disinterested witnesses signed, California presumes the beneficiary-witness got their gift by fraud or undue influence. Unless they overcome that presumption, they receive only what they would have inherited under intestacy, which may be nothing.3California Legislative Information. California Probate Code 6112
The clean fix: choose two witnesses who aren’t mentioned anywhere in the will. Neighbors, coworkers, or friends without any gift work well.
A Note on Witnesses After You Die
California does not offer a notarized self-proving affidavit at signing the way most states do. After death, a subscribing witness can submit a sworn statement along with a photographic copy of the will to satisfy the probate court. That means your witnesses may need to be located later. Pick people who are younger than you, easy to find, and likely to still be reachable years from now.
Which Type of Will to Use
California recognizes three forms. The right one depends on how complex your situation is.
Witnessed (Formal) Will
The standard option: a typed document signed by you and two witnesses under the rules above. It can cover specific gifts, trusts for minor children, conditions on inheritance, and detailed instructions for your executor. Done carefully, it’s the hardest form of will to challenge, and it’s what most people should use.
Holographic Will
A holographic will is entirely in your own handwriting, signed by you, with all material terms written out by hand. No witnesses required. Dating it isn’t strictly required for validity, but leaving the date off causes real trouble: if an earlier will exists and conflicts with the holographic one, the undated version loses unless someone proves it came later.4California Legislative Information. California Probate Code 6111
Handwritten wills are useful in emergencies but risky as a real plan. Handwriting disputes, ambiguous language, and no witnesses all make them easier to contest.
Statutory Will
California publishes a fill-in-the-blank will form directly in the Probate Code. You enter your name, beneficiaries, executor, and guardian nominations, then sign it in front of two witnesses like any formal will.5California Legislative Information. California Probate Code 6240 You cannot cross anything out, add words, or modify the pre-printed language. If you do, the court may strike the changes or the entire will.
The statutory will suits someone with a simple picture: a spouse, children, and ordinary personal property. It stops being enough once you own a business, need a trust inside the will, have a beneficiary with special needs, or want conditions attached to any gift.
Decisions to Make Before You Draft
Who Gets What
List each person or organization receiving something from your estate. Use full legal names and relationships so no one can argue about who you meant. “My nephew James” is fine if there is one James. If there are two, expect a fight.
Separate specific gifts from the residuary estate. A specific gift is a particular item or dollar amount, like a ring to a daughter or $10,000 to a named charity. The residuary is everything left after specific gifts and debts are paid. Name a residuary beneficiary, because anything you acquire after signing the will falls into that bucket automatically.
Who Runs the Estate
Your executor, called a personal representative in California, files the will with the court, inventories your property, pays debts and taxes, and distributes what’s left. Pick someone organized, trustworthy, and willing to handle paperwork and deadlines for months. Name at least one backup in case your first choice can’t serve.
Who Raises Your Children
If you have children under 18, name a guardian in the will. A court makes the final call, but judges lean heavily on a parent’s written nomination. Without one, relatives may fight, or a judge may appoint someone you’d never have chosen. Talk to the person first. Being told after the fact that you have possible custody of someone’s kids is not a pleasant discovery.
Community Property Limits What You Can Give
California is a community property state, and that changes what your will actually controls. What you and your spouse earned or acquired during the marriage is generally community property, with each of you owning an undivided half. When you die, only your half is available to leave by will. Your spouse’s half already belongs to them, and your will has no power over it.6Justia Law. California Probate Code 100-105
Your separate property, meaning anything you owned before the marriage, gifts and inheritances received during it, and anything earned after a legal separation, is fully yours to distribute however you like.
The trap is commingling. Deposit an inheritance into a joint checking account and let it mix with marital money over years, and proving it stayed separate can become almost impossible. If you have significant separate assets, keep them in their own accounts and hold on to records showing where they came from.
Assets Your Will Does Not Control
A common misconception is that a will governs everything you own. It doesn’t. Several kinds of assets transfer automatically at death and ignore whatever your will says.
- Life insurance, 401(k)s, IRAs, and annuities pass to whoever is named on the beneficiary form. If your will leaves everything to your children but your ex-spouse is still the named beneficiary on a retirement account, the ex-spouse gets that account.
- Real estate or bank accounts held in joint tenancy with right of survivorship go to the surviving co-owner automatically, without probate.
- Payable-on-death bank accounts and transfer-on-death brokerage accounts go directly to the named person.
- Community property with right of survivorship, a special ownership form for California spouses, passes entirely to the surviving spouse and gets a full stepped-up tax basis on both halves.
- Assets you’ve transferred into a revocable living trust pass under the trust, not the will.
Review your beneficiary designations every few years, and after every major life event. A carefully drafted will can be silently overridden by a form you filled out at work a decade ago and forgot.
Signing and Storing the Will
Sign in ink, in front of both witnesses, at the same time and place. Have each witness sign after you, in your presence and in each other’s presence. Initial each page if you want extra protection against page substitution claims.
A perfectly drafted will is useless if no one can find it. California requires whoever has custody of the will to deliver it to the court within 30 days of learning of the death. A fireproof home safe is practical. A bank safe deposit box seems safer but creates a catch: your family may need a court order to open the box, and the box contains the very document the court needs to see. If you use one, make sure your executor or agent under a power of attorney has explicit access before you die. Tell at least two people you trust where the original is kept, and give your executor a copy clearly labeled as a copy.
Changing or Revoking It Later
Your will should keep pace with your life. California gives you three ways to update or eliminate one.
Codicils
A codicil is a written amendment to an existing will and must be signed and witnessed with the same formality as the original. Codicils suit small changes, like swapping an executor. For anything more, writing a new will is cleaner and less likely to leave anyone guessing which version wins.
A New Will
A new will can revoke the old one, either by saying so directly or by being so inconsistent that both can’t stand.7Justia Law. California Probate Code 6120-6124 – Revocation and Revival Include an explicit revocation clause at the top and destroy the earlier copies. Leaving conflicting wills scattered around invites litigation.
Physical Destruction
Burning, tearing, or otherwise destroying the will, done by you or by someone acting in your presence at your direction, revokes it if you intended the act to revoke.7Justia Law. California Probate Code 6120-6124 – Revocation and Revival Be careful with duplicates. Destroying one copy of a will executed in duplicate revokes the entire will.8California Legislative Information. California Probate Code 6121
Divorce Cuts Out an Ex-Spouse Automatically
Once a divorce or annulment is finalized, California automatically revokes every provision in your will that benefits your former spouse, including gifts, executor nominations, and any powers of appointment. The property that would have gone to the ex passes as if the ex-spouse died before you.9California Legislative Information. California Probate Code 6122
Two limits to know. The automatic revocation only kicks in once divorce or annulment is final. Legal separation without a divorce leaves your spouse’s rights under the will fully intact.9California Legislative Information. California Probate Code 6122 Second, no other life change updates your will for you. Remarriage, a new child, a move to another state: none of those trigger anything automatic. You have to update the document yourself.
When to Bring in an Attorney
A simple will is manageable on your own, and the statutory will form makes it more so. Some situations push past what any form can handle:
- Blended families where you want to provide for a current spouse while preserving assets for children from a prior relationship.
- Business ownership, where a will that ignores buy-sell agreements or LLC operating provisions can freeze a company.
- A beneficiary with special needs, where a direct inheritance can disqualify them from government benefits and a special needs trust is the fix.
- Significant real estate, especially property in more than one state, which can trigger probate in each state without proper planning.
- Digital assets like cryptocurrency, online businesses, or valuable accounts that need explicit executor authorization.
- Estates approaching the federal estate tax threshold, which applies to individuals with estates exceeding $15 million, or $30 million for married couples using portability. California itself imposes no state estate tax.10Internal Revenue Service. What’s New – Estate and Gift Tax
An attorney also makes sense if you just want confidence the document will hold up. The cost of a basic estate plan is small next to what a family spends fighting a flawed will in probate court.
