How to Write a Simple Will in California (And When You Need an Attorney)

You have worked hard your entire life. You have a home, a bank account, maybe a small business, and people you love deeply. Yet millions of Californians go years without a will, often assuming it is too complicated, too expensive, or something they can handle later. Here is the reality: dying without a will in California means the state decides who gets everything you built. And that decision might look nothing like what you would have chosen.

The good news is that writing a will in California is more straightforward than most people think. Whether you are a longtime San Luis Obispo resident or just moved to Atascadero, this article walks you through what you need to know about how to write a will in California, the legal requirements you must meet, and the situations where having an attorney in your corner is the right call.

What Is a Will and Why Does It Matter?

A will, formally called a last will and testament, is a written legal document that specifies how your property should be distributed after your death. Through a will, you can name beneficiaries to receive specific assets, appoint a guardian for your minor children, designate an executor (called a personal representative in California) to manage your estate, and provide instructions for your funeral or final arrangements.

If you die without a valid will, California’s intestate succession laws take over. Under California Probate Code § 6400 et seq., the state distributes your property according to a fixed formula based on family relationships. Unmarried partners who are not registered domestic partners generally inherit nothing under intestacy, while registered domestic partners inherit similarly to a spouse. Your property might go to relatives you have not seen in years, and your close friends or long-term partners could receive nothing. A properly executed will ensures your wishes are followed and gives you control over who inherits your property.

What Are the Requirements for a Simple Will in California?

Before you put pen to paper or open a word processor, you need to understand what makes a will legally valid. California law sets out these requirements primarily in California Probate Code §§ 6100–6111.

1. Age requirement. You must generally be at least 18 years old to make a will. However, emancipated minors who are at least 16 years old may also create a valid will under California Probate Code § 6100.
2. Testamentary capacity. You must be of sound mind, meaning you understand what a will is, what property you own, who your natural heirs are, and how the document distributes your assets. If your mental capacity is in question at the time of signing, the will can be challenged in probate court.
3. Written form. California law requires that a will be in writing. Oral wills are not valid. Your will may be typed or handwritten. A voicemail, video recording, or verbal statement to family members does not qualify as a will.
4. Signature. Under California Probate Code § 6110, the will must be signed by you, the testator, or by another person in your presence and at your direction if you are unable to sign yourself.
5. Witnesses. A typed or printed will generally requires two witnesses who are present at the same time when you sign or acknowledge your signature. Each witness must understand that the document is your will. Witnesses may be named as beneficiaries, but under California Probate Code § 6112, gifts to a witness create a presumption of undue influence. The gift may be limited to what the witness would inherit under intestate succession unless the presumption is rebutted.
6. Notarization. Notarization is not required for a will to be valid in California. However, if your witnesses sign a self-proving affidavit under penalty of perjury under California Probate Code § 8220, the will becomes “self-proving.” This means the probate court can accept the will without contacting the witnesses, saving time and potential complications.

Is a Do-It-Yourself Will Valid in California?

Yes, a do-it-yourself will can be valid in California, as long as it meets all the legal requirements outlined above. Many people create their own wills, and if properly executed, these documents can be upheld in probate court.

California also offers a Statutory Will under California Probate Code § 6240. This is a fill-in-the-blank template available through the California State Bar for free. It is designed for individuals with relatively simple estates. While the form should generally be followed closely to avoid invalidation, minor variations that do not affect the essential provisions may be accepted by a court. Major alterations, however, could jeopardize the will’s validity.

Online will-drafting platforms are another option. These platforms can produce legally valid wills if the resulting document complies with California law, including witness requirements and rules around community property. However, the quality of online forms varies, and some may not address California-specific rules adequately, particularly for married individuals or blended families.

Holographic wills are handwritten wills recognized under California Probate Code § 6111. A holographic will is valid if all material provisions are written entirely in the testator’s handwriting and the will is signed by the testator. Typed additions or pre-printed forms within the holographic will can invalidate it. Holographic wills do not require witnesses, but because there are no witnesses to confirm the circumstances of signing, they are more likely to be challenged in probate. For this reason, estate planning professionals generally do not recommend relying on a holographic will as a primary planning tool.

What Should Your Will Include?

A well-drafted simple will in California typically includes the following:

• Your identity — your full legal name and county of residence.

• Revocation clause — a statement that this will revokes any prior wills or codicils.

• Beneficiary designations — who receives your property and in what proportions.

• Specific bequests — particular items or amounts left to specific people.

• Residuary clause — who receives any property not specifically named.

• Executor (personal representative) designation — the person who will administer your estate.

• Guardian designation — if you have minor children, who will care for them.

• Signature and witness attestation — the testator’s signature and the required witnesses or self-proving affidavit, depending on the type of will.

Important note for married Californians: California is a community property state, meaning property acquired during marriage is generally owned equally by both spouses. Your will can only control your half of community property and all of your separate property. It cannot dispose of your spouse’s half of community property without their consent. Failing to account for this distinction is a common and costly mistake in do-it-yourself wills.

When Do You Need an Attorney to Write Your Will?

A straightforward will for someone with modest assets, no minor children, and a clear plan for distribution can reasonably be done without an attorney. But several circumstances call for professional legal help.

You should strongly consider working with an estate planning attorney if any of the following apply to you:

• You own real property, especially if it is held jointly or in multiple states
• You have minor children and want to create a trust to manage their inheritance
• You are in a blended family with children from a prior relationship
• You own a business or have significant retirement accounts, stock options, or investment portfolios
• You have a family member with special needs who receives government benefits
• You want to minimize estate taxes or structure gifts in a tax-efficient way
• You are concerned a family member might contest the will
• You recently went through a divorce, remarriage, or significant change in assets

In these situations, a will drafted without legal guidance can end up costing your family far more in probate than an attorney would have charged to draft it properly. An attorney can also help coordinate your will with other planning tools, like a living trust, powers of attorney, and advance health care directives, so that your entire plan works together rather than creating gaps or conflicts.

What Happens After You Write Your Will?

Once your will is signed and witnessed, store it in a safe and accessible location. Options include a fireproof safe at home, a safety deposit box, or with your attorney. Make sure your executor knows where to find the original will.

After your death, the person in possession of your original will must file it with the probate court within 30 days if probate proceedings are being opened (Probate Code § 8200). There is no requirement to file the will if probate is not initiated.

It is also important to review and update your will after major life events, such as marriage, divorce,  the birth of a child or grandchild, the death of a named beneficiary or executor, or a significant change in your financial situation. You can update a will by creating a new one that expressly revokes the old will or by drafting a codicil, which is a formal amendment to the existing document (Probate Code §§ 6120–6122).

Key Takeaways

• Any California resident who is 18 or older and of sound mind can make a will. Emancipated minors aged 16 or older may also make a valid will.
• A typed or printed will must be signed by the testator and witnessed by at least two qualifying witnesses. Gifts to a witness create a presumption of undue influence under Probate Code § 6112.
• A holographic will must have all material provisions entirely in the testator’s handwriting and be signed. Witnesses are not required, but having them can reduce challenges to the will.
• California’s Statutory Will form under Probate Code § 6240 is a free, fill-in-the-blank option for simple estates. Minor modifications may be allowed, but major changes could risk invalidation.
• Do-it-yourself wills can be valid if properly executed, but errors in signing, witnessing, or failing to account for California-specific rules (e.g., community property, blended families) can make them unenforceable.
• Complex family situations, real property, blended families, business ownership, and beneficiaries with special needs warrant professional legal assistance.
• Your will should be reviewed and updated after major life events, such as marriage, divorce, the birth of a child or grandchild, the death of a beneficiary or executor, or significant changes in your finances.

Frequently Asked Questions

Does my will need to be notarized in California? 

No. Notarization is not required for a will to be valid in California. However, having your witnesses sign under penalty of perjury makes the will self-proving under California Probate Code § 8220, which can simplify the probate process.

Can I write my will by hand? 

Yes. A holographic will that is written and signed entirely in your own handwriting is recognized under California Probate Code § 6111. No witnesses are required, but they are strongly recommended to reduce the risk of a challenge.

What happens if I die without a will in California? 

Your estate will be distributed according to California’s intestate succession laws under Probate Code § 6400 et seq. This formula is based strictly on blood and marital relationships and may not reflect your wishes at all.

Can I disinherit a spouse or child in California? 

Partially. California law protects spouses through community property rights, and there are legal protections for pretermitted children (children accidentally left out of a will). An attorney can help you navigate these rules if you have specific disinheritance intentions.

How often should I update my will? 

There is no fixed rule, but reviewing your will every three to five years, and after any major life change, is a reasonable approach.

Is an online will valid in California? 

An online will is valid if it meets all the requirements under California Probate Code § 6110, including being signed by the testator in the presence of two qualifying witnesses. The platform you use does not determine validity; the execution does.
