Writing a will in California is more straightforward than most people assume — but the details matter. Miss a requirement and the document is invalid. Name the wrong beneficiary and your estate ends up in probate anyway. This guide covers California’s legal requirements, what every will should include, the three types of California wills, and when a simple DIY document is sufficient versus when you need an attorney.
California Probate Code §§ 6100–6113 establishes the legal requirements for a valid will. A will that fails these tests will not be admitted to probate — meaning it won’t be enforced.
For a typed (attested) will, California requires:
California is one of the states that recognizes holographic wills under Probate Code § 6111. A holographic will is valid without any witnesses — but the requirements are strict:
Holographic will caution: While legally valid, holographic wills are more frequently challenged in California courts. Without witnesses, there is no one to attest to your mental capacity or that the document represents your genuine wishes. For most families, a properly witnessed typed will — or a typed will paired with a trust — is the better choice. Use a holographic will only in genuine emergencies when no other option exists.
A legally valid will satisfies the signature and witness requirements. A complete will does the job you actually need it to do. These are the provisions that belong in every California will:
Name the person responsible for carrying out your will — collecting assets, paying debts, filing the final tax return, and distributing property. Name a successor executor in case your first choice is unable to serve. In California, your executor must be 18+ and a California resident or a close family member if out-of-state.
If you have children under 18, name a guardian in your will. Courts are not bound by your choice but give it significant weight. Without a named guardian, the court decides entirely on its own. Name a successor guardian as well.
State clearly who receives what. Be specific about real property (include the address), vehicles, bank accounts, and personal property. Vague language like “divide equally among my children” invites disputes. If the asset has a deed or title, identify it by description.
List items of sentimental or financial value you want to leave to specific people — jewelry, heirlooms, collectibles, vehicles. If the item no longer exists at your death, the bequest simply fails (called “ademption”); you can add language addressing what happens if the item is gone.
A residuary clause captures everything not covered by specific bequests — assets you acquire after signing the will, items you forgot to list, and anything whose specific bequest failed. Without one, those assets pass under California intestacy law, which may not reflect your wishes.
Authorize your executor to access online accounts, email, social media, cryptocurrency wallets, and cloud storage. California’s RUFADAA (Revised Uniform Fiduciary Access to Digital Assets Act) requires explicit language in your will or a separate online tool designation to grant this access. Without it, your executor may be locked out legally. See our guide: Organizing Your Digital Estate.
California recognizes three types of wills, each with different use cases:
| Type | How It Works | Best For | Watch Out For |
|---|---|---|---|
| Simple Will | Typed, signed, witnessed by two non-beneficiaries. Distributes assets directly to beneficiaries at death. | Single adults, younger families, estates under the $184,500 probate threshold, straightforward asset distribution | Assets still go through probate if titled in your name alone; no probate avoidance |
| Pour-Over Will | Paired with a revocable living trust. At death, any assets not already in the trust “pour over” into it for distribution under trust terms. | Anyone who has a living trust. Acts as a safety net for assets accidentally left out of the trust. | Assets that pour over still go through probate before reaching the trust; the goal is to fund the trust fully during your lifetime |
| Holographic Will | Entirely handwritten, dated, and signed by the testator. No witnesses required under California law. | Emergency situations only — when no other option is available. Not recommended as a primary planning tool. | Easier to challenge, harder to prove capacity, no witnesses, higher risk of errors or ambiguity |
Will vs. trust: A will is not enough to avoid California probate for most homeowners. If your estate exceeds $184,500 — which most San Diego homeowners do — a revocable living trust paired with a pour-over will is the standard recommendation. The trust avoids probate; the will catches anything left out of the trust. Read our full breakdown in the Estate Planning Checklist for San Diego Families.
These are the errors that turn a completed will into a family dispute — or no will at all:
Marriage, divorce, the birth of a child, the death of a beneficiary, a major asset purchase — any of these can make your existing will work against you. In California, a divorce automatically revokes provisions benefiting your former spouse, but remarriage does not automatically update your will. Review your will after every significant life change.
California law does not allow minors to directly receive significant assets. If you leave assets to a child under 18 without a trust, the court appoints a conservator to manage the funds until the child turns 18 — at which point they receive everything at once with no strings attached. Use a testamentary trust or name a custodian under the California Uniform Transfers to Minors Act instead.
Online accounts, cryptocurrency, domain names, digital photos, and cloud storage are invisible to probate courts and to executors without explicit authorization. Under California’s RUFADAA, your executor needs a will provision or online tool designation to legally access these accounts. A will written before 2016 almost certainly lacks this language — update it.
Every new will should begin with a clear revocation clause: “I revoke all prior wills and codicils.” Multiple wills in existence create confusion and litigation. Courts try to reconcile conflicting documents — they may not reach the conclusion you intended. Start clean with each new will.
A typed California will is invalid without two disinterested adult witnesses who sign in your presence. Common errors: only one witness, a witness who is also a beneficiary, signing before the witnesses arrive. All three of you must be in the same room when you sign; then both witnesses sign. Order matters.
Beneficiary designations override your will. Life insurance, 401(k)s, IRAs, and accounts with payable-on-death designations pass outside your will entirely. An outdated beneficiary designation routes assets to an ex-spouse or deceased relative regardless of what your will says. Review these separately — they are not part of your will.

Not every California will requires an attorney. The honest answer depends on your situation:
| Your Situation | DIY Sufficient? | Why |
|---|---|---|
| Single adult, no children, straightforward assets | ✓ Often yes | Simple distribution, low risk of dispute, estate likely under probate threshold |
| Married couple, minor children, one San Diego property | ✓ Possibly — but get a trust review | Guardian designation and asset distribution are straightforward; probate avoidance requires a trust, which is better attorney-drafted |
| Blended family, stepchildren, children from prior marriage | ✗ Attorney recommended | California intestacy favors biological children; blended families require precise drafting to avoid unintended disinheritance |
| Business ownership (sole proprietor, LLC, S-corp interest) | ✗ Attorney required | Business succession requires coordination with operating agreements, buy-sell agreements, and business valuation |
| Real estate in multiple states | ✗ Attorney required | Each state has its own probate laws; multi-state real estate typically requires ancillary probate in each state unless held in a trust |
| Complex assets (cryptocurrency, private equity, foreign accounts) | ✗ Attorney recommended | Valuation, access, and transfer of non-standard assets requires specific drafting to avoid loss or delay |
| Anticipated family disputes or contested relationships | ✗ Attorney strongly recommended | A no-contest clause and attorney-drafted will with a clear record of capacity reduces successful challenges |
If you’re in the “DIY sufficient” column, a reputable online service (LegalZoom, Trust & Will, Nolo) or California’s Judicial Council statutory will form (DE-140) can produce a legally valid document. If you’re in the attorney column, the cost of getting it right is far less than the cost of probate litigation.
