California Will Requirements at a Glance

Here are the exact rules for making a valid will in California:

Minimum age to make a will 18 (Probate Code section 6100(a) — an individual 18 or more years of age who is of sound mind may make a will; no exception for emancipated minors)
Witnesses required 2 (Probate Code section 6110(c)(1) — both witnesses must be present at the same time and must each witness the testator’s signing or the testator’s acknowledgment of the signature or the will, and must understand the instrument is the testator’s will; any person generally competent to be a witness may serve under section 6112(a); a beneficiary may serve as witness but if fewer than two other disinterested witnesses exist, a rebuttable presumption of undue influence arises under section 6112(c))
Notarization required NO — notarization is not required to make a valid California will; it is optional and may be used for a self-proving affidavit to streamline probate, but it does not substitute for the two-witness requirement
Handwritten (holographic) will allowed YES — California recognizes holographic wills under Probate Code section 6111(a); no witnesses are required; the testator’s signature and the material provisions (who gets what) must be in the testator’s own handwriting; a date is strongly recommended but not required — however an undated holographic will that conflicts with another will is invalid to the extent of the inconsistency unless its later execution date can be proven (section 6111(b)(1)); printed form language may supply statements of testamentary intent, but all material provisions must be handwritten (section 6111(c))
Self-proving affidavit available YES — California permits a self-proving affidavit under Probate Code sections 8220-8222; the testator and witnesses sign an affidavit before a notary public confirming proper execution; this is optional, not required; its purpose is to streamline probate by potentially eliminating the need for witnesses to testify in court; California uses its own framework rather than the Uniform Probate Code’s standard two-step or one-step process
Statutory will form YES — California provides an official statutory fill-in-the-blank will form codified directly in Probate Code section 6240 (Chapter 6, sections 6200-6248); the form is free to use and available from county law libraries, the California State Bar, and the California Courts Self-Help portal; it must be signed by the maker and two witnesses; the statutory language cannot be modified — only the blanks may be filled in; it is designed for simple estates and does not accommodate trusts or complex distributions

What a California Will Does (and Doesn’t Do)

In California, a valid will may name an executor (personal representative) to administer the estate through probate; name a guardian for minor children (subject to court approval); distribute the testator’s separate property and the testator’s one-half share of community property; create testamentary trusts; make specific bequests, residuary gifts, and conditional gifts; and disinherit heirs (with certain statutory limits for omitted spouses and children)

What a California will does NOT control: A California will does not control assets that pass outside probate — including life insurance proceeds with a named beneficiary, retirement accounts (401(k), IRA) with a named beneficiary, payable-on-death (POD) and transfer-on-death (TOD) accounts, joint tenancy property (passes by right of survivorship), and assets held in a living trust;

a will also cannot dispose of the surviving spouse’s one-half of community property (Probate Code sections 100-101); a will cannot override an omitted spouse’s statutory share under sections 21610-21612 or an omitted child’s share under sections 21620-21623; conditions that violate public policy are unenforceable

Oral wills in California: NO — California does not recognize oral (nuncupative) wills under any circumstances; Probate Code section 6110 requires all wills to be in writing; there is no exception for military service or imminent peril

How to Update or Revoke a California Will

A California will may be amended by executing a codicil — a separate written document that changes specific provisions of the existing will; a codicil must meet the same execution requirements as a will (written, signed, witnessed by two persons); a will may be revoked under Probate Code section 6120 by (1) a subsequent will that expressly revokes the prior will or revokes it by inconsistency,

or (2) physical destruction (burning, tearing, canceling, obliterating, or destroying) with the intent to revoke, done either by the testator or by another person in the testator’s presence and at the testator’s direction; if a will was executed in duplicate, destroying one copy with revocatory intent revokes both (section 6121); you may not validly update a typed or printed will by crossing out words or adding handwritten corrections

Other California will-making rules: California is a community property state (one of 9), meaning each spouse owns an undivided one-half of community and quasi-community property — a will can only control the decedent’s half; California has no elective share statute (unlike most common-law property states) because the community property system itself protects the surviving spouse;

California recognizes a harmless error doctrine under Probate Code section 6110(c)(2) — even a will that fails witness requirements may be admitted to probate if the proponent proves by clear and convincing evidence that the testator intended the document to be their will;

omitted spouse protections (sections 21610-21612) and omitted child protections (sections 21620-21623) may entitle a spouse married or child born after the will’s execution to a statutory share unless the omission was intentional and documented; California does not currently recognize electronic wills — a will must be on paper (typed, printed, or handwritten); the 2026 small estate threshold allowing simplified transfer without full probate is 208850

Understanding California Estate Planning

Getting started with California estate planning is the single best gift you can give your family. A valid California will lets you decide who inherits, name an executor, and name a guardian for your children — instead of leaving it to a default state formula.

When people look into California estate planning, the real answer comes down to the state’s execution rules: your age, the number of witnesses, and whether you make it self-proving. If any part of California estate planning is unclear, your state court’s self-help center can point you to the official forms and resources.
