What the rule says
California protects children born or adopted by a testator after the testator executes a will. Under California Probate Code §§ 21620–21623, a child of the testator who is born or adopted after the will is executed, and who is not provided for in the will, is entitled to a share of the estate equal to what the child would have received if the testator had died intestate.
The rule recognizes that a will written before a child is born often does not anticipate that child. California treats the omission as presumptively unintentional and gives the child a statutory share rather than allowing the will to silently disinherit them.
The omitted-child share is calculated against the estate as a whole, with the child taking the same share they would have received under California intestacy. For a married parent with shared descendants, this generally means the child takes a share of the separate property along with other children, while the surviving spouse takes community property and a fraction of separate property under California Probate Code § 6401.
The three exceptions
The omitted-child share does not apply if any of the following is true:
1. The omission was intentional and the will or other evidence demonstrates that intent. Express language in the will indicating that the testator did not intend to provide for any future child satisfies this exception. So does extrinsic evidence — letters, conversations memorialized in writing, or other proof — establishing intentional omission. 2. The testator provided for the child outside the will. A trust, life insurance designation, retirement plan beneficiary designation, or other arrangement that provides for the omitted child can satisfy this exception. Under California Probate Code § 21621, the provision must appear from "statements of the decedent or from the amount of the transfer or other evidence." 3. The testator devised substantially all of the estate to the other parent of the omitted child. California Probate Code § 21621(a)(2) treats this as adequate provision: the surviving parent is presumed to provide for the child indirectly. The exception fails if the other parent does not survive the testator.
If any of these three exceptions applies, the omitted child takes only what the will provides — which may be nothing.
Limits on the protection
The omitted-child statute has clear scope limits:
- The protection extends only to children of the testator born or adopted after will execution. A child existing at the time of the will's execution but simply not mentioned is not an omitted child under this statute (though other doctrines may apply). - The protection extends to biological and legally adopted children. Stepchildren who were never adopted by the testator are not omitted children, even if they joined the family after the will was signed. - The protection does not adjust the will's overall structure. Other beneficiaries' shares are reduced proportionally to fund the omitted child's intestate share, but specific bequests of identified property generally remain intact unless the share cannot be funded otherwise.
California also has a separate provision (Cal. Probate Code § 21622) for children believed to be dead at the time the will was executed, who turn out to be living. Such children are also entitled to an intestate share.
What you can do about it
Updating the will after the birth or adoption of a child is the most reliable approach. A new will, or a codicil, that names the child and either provides for them or expressly disinherits them with a clear reason eliminates ambiguity and forecloses any omitted-child claim.
If updating the will is impractical immediately, several alternatives can satisfy the "otherwise provided for" exception:
- Beneficiary designations on life insurance, IRAs, 401(k)s, or other non-probate accounts naming the child - A trust established for the child's benefit with assets transferred during life - Custodial accounts under the California Uniform Transfers to Minors Act
None of these is a complete substitute for an updated will, because they may not match what the testator would have wanted in proportion or timing. They do, however, prevent the after-born child from being categorized as omitted under the statute.
Who this affects most
The omitted-child rule is most relevant for:
- California parents who executed a will before having children - California families where a child was born or adopted after a previously executed will - Estates where the will is significantly older than the youngest child - Adoptive families who completed adoption after a previously executed will - Married couples who relied on the "substantially all to other parent" exception but whose family circumstances later changed
California does not require parents to update their will every time the family expands. It does provide a default protection so that an unupdated will does not unintentionally disinherit a child. Updating the will after a major family change replaces the default with the parent's actual choice.
