How to Disinherit Someone in Your Will in California

Short Answer: Yes, California law generally allows you to disinherit an adult child, sibling, parent, prior spouse, or other family member. However, a valid disinheritance requires more than leaving a name out of a will or trust. Your estate plan should use express language, properly address omitted spouse and omitted child rules, account for community property rights, and coordinate non-probate assets such as life insurance and retirement accounts. A surviving spouse cannot be deprived of their own one-half interest in community property.

Disinheritance can protect an estate from family disputes, but unclear estate documents often create the exact probate litigation they were meant to prevent.

Why Silence Is Not Always Disinheritance

A testator may choose who receives an inheritance and who does not. Still, omission and express disinheritance are not the same thing.

If a will instrument or trust instrument simply fails to mention an adult child, sibling, parent, or former spouse, the disinherited person may argue that the omission was inadvertent. That argument becomes more serious in blended families, after remarriage, reconciliation, divorce, or the birth or adoption of a child.

Use a direct disinheritance clause in the applicable testamentary instruments. The clause should identify the intended disinherited person and state that the omission is intentional. A residuary clause should also state where the remaining residuary estate will go if the excluded family member does not inherit.

A properly drafted estate plan reduces the risk of an omitted heir claim, an inheritance claim, and later estate litigation.

California’s Protected Heirs

California law recognizes important statutory protection for certain omitted heirs, also called pretermitted heirs. Under Cal. Prob. Code §§ 21600–21612, an omitted spouse or omitted child may have inheritance rights despite language in an older will or revocable living trust.

Person	Key California Rule
Surviving spouse	Cannot be disinherited from their own community property rights; each spouse generally owns one-half of community property
Post-marriage spouse	A spouse married after execution of estate documents may have statutory rights unless an exception or clear estate plan applies
Post-execution child	A born child or adopted child may have rights if omitted from testamentary documents executed before the birth or adoption
Adult child	Generally may be expressly disinherited, subject to valid execution and no successful legal challenge
Minor child	Can be disinherited, but careful estate planning is essential because guardianship, support, protective trusts, and family circumstances may affect the plan
Prior spouse	Divorce can affect beneficiary rights and estate distribution, but all estate documents and beneficiary designation forms should be reviewed

A surviving spouse’s property rights differ from inheritance rights. A will cannot give away property that belongs to the surviving spouse. In California, the decedent’s estate generally includes only the decedent’s one-half interest in community property, plus their separate property.

Use Express Language in Every Document

The strongest approach is express disinheritance in both the will and trust when both documents form part of the estate plan.

Your estate planning attorney may use language stating that a named family member is intentionally omitted and will receive no bequest, beneficiary inheritance, or share of the estate assets. The clause should be tailored to the situation rather than copied from a generic form.

A complete plan may include:

• A will with an express disinheritance clause and residuary clause

• A revocable living trust identifying beneficiaries and excluded persons

• Updated trust administration instructions for the fiduciary

• Updated beneficiary designation forms for retirement accounts and life insurance

• Review of payable-on-death accounts and transfer-on-death accounts

• Review of joint tenancy property, which may pass outside probate

• A durable record of execution formalities and capacity evidence

This matters because many assets are non-probate assets. A will does not override a valid beneficiary designation, joint tenancy title, or payable-on-death account arrangement. If an old retirement account still names the disinherited person as beneficiary, that account may pass to them despite the terms of the will.

Avoid the Intestacy Trap

If a will or trust does not effectively dispose of property, that property may pass through intestate succession. Under Cal. Prob. Code §§ 6400–6455, property not effectively disposed of by a will passes to heirs in the statutory order.

That result can undermine intentional disinheritance. For example, if a residuary estate provision fails, probate assets may pass to heirs under California probate law, including a child, parent, sibling, or other heir whom the decedent intended to exclude.

An estate plan should therefore address:

• Probate assets and non-probate assets

• Separate property and community property

• Estate distribution if a beneficiary dies first

• Contingent beneficiaries

• Creditor claims and estate administration expenses

• The effect of divorce, remarriage, birth, adoption, and changed family relationships

Proper planning prevents a partial intestacy from creating unexpected inheritance rights.

Make the Documents Difficult to Challenge

A disinherited person may attempt a will contest or trust contest. Common grounds for a legal challenge include lack of capacity, undue influence, fraud, duress, forgery, or failure to follow legal execution requirements.

California law provides that execution or revocation of a will may be ineffective to the extent it was procured by duress, menace, fraud, or undue influence. A challenge may also claim that the testator lacked testamentary capacity at the signing ceremony.

Practical protections include:

• Use an experienced estate planning attorney rather than do-it-yourself forms

• Conduct a formal signing ceremony with appropriate witnesses

• Keep capacity evidence when health or family conflict could lead to litigation

• Consider a physician evaluation when capacity may be disputed

• Avoid having a favored beneficiary control communications or participate improperly

• Maintain attorney notes, witness records, and legal documentation

• Review the plan after marriage, divorce, death, adoption, or a major asset change

These steps can help the probate court evaluate whether the testamentary document reflects the testator’s actual intent.

No-Contest Clauses Have Limits

A no-contest clause, also called an in terrorem clause, can discourage certain contests by imposing forfeiture consequences on a beneficiary who brings a prohibited challenge. However, it is not a universal shield against estate litigation.

Under Cal. Prob. Code §§ 21310–21315, including Cal. Prob. Code § 21310 and Cal. Prob. Code § 21311, a no-contest provision is enforceable only in defined circumstances. A direct contest generally must lack probable cause before a forfeiture result can apply.

For that reason, no-contest clauses work best as one component of a larger legal protection strategy, not as a substitute for clear documents, proper execution, and evidence of testamentary capacity.

FAQ’s

Can I disinherit my adult child in California?

Usually, yes. An adult child does not automatically have a legal right to inherit if a valid will or trust uses express language to disinherit them. However, the plan should avoid inadvertent omission issues and should dispose of all estate assets.

Can I disinherit my spouse?

You generally cannot disinherit a surviving spouse from their own community property rights. The surviving spouse retains their one-half interest in community property, while the decedent may control the disposition of their own property interests and separate property, subject to California statutory law.

Does leaving someone out of my will disinherit them?

Not always. Silence can create questions about inadvertent omission, particularly involving an omitted spouse, post-marriage spouse, omitted child, or post-execution child. Express language is more reliable.
