Disinheritance is legally available in California for most potential beneficiaries. An adult child, a sibling, a parent, a prior spouse — none of these has a legal right to inherit from you, and you may exclude them from your estate plan without explanation, legal justification, or their consent.
Two categories of person cannot be fully disinherited under California law: a surviving spouse (who retains community property rights regardless of what any will or trust says) and certain omitted heirs (a spouse who married after the will was executed, or a child born or adopted after the will was signed) unless specific disinheritance language addresses them expressly.
Beyond those categories, the mechanics of effective disinheritance involve more than simply omitting a name. Assets that pass outside of a will or trust — retirement accounts, life insurance, joint tenancy property — are unaffected by estate planning documents and require separate attention. A no-contest clause can reinforce the plan but, since 2010, its deterrent effect in California is significantly weaker than most clients assume.
California is a community property state. All income earned by either spouse during the marriage, and all property acquired with that income, is owned equally by both spouses — regardless of whose name appears on the account or deed. At death, the decedent may dispose of only their one-half of community property. The surviving spouse already owns the other half; it does not pass through the estate at all, and no will or trust can reach it.
A testator who attempts to leave the surviving spouse’s half of community property to someone else has no legal authority to do so. The transfer is void as to that half. In practice, this means a surviving spouse cannot be “disinherited” with respect to community property — the legal question does not arise because the property was never solely the decedent’s to give.
The decedent may, however, dispose of their one-half of community property and all separate property (property owned before marriage, or acquired during marriage by gift or inheritance) as they choose — including leaving it entirely to someone other than the surviving spouse.
An omitted heir is a person who would be entitled to inherit under California law but who is not mentioned in the will or trust — not because the testator intended to exclude them, but because the will predates their arrival in the family. California law presumes, in certain circumstances, that the omission was inadvertent and awards the omitted heir a share of the estate regardless of the will’s terms.
The omitted heir categories are:
If a testator intends to exclude any of these persons — knowing of their existence or anticipating the possibility — the will or trust must expressly say so. Silence is interpreted as inadvertent omission, not intentional disinheritance. A general disinheritance clause that addresses this category by name eliminates the ambiguity.
Assets that are not disposed of by a valid will or trust, and that do not pass by beneficiary designation or operation of law, pass by intestate succession to the decedent’s heirs in a fixed statutory order. A disinheritance plan that fails to account for every asset — leaving any asset without a designated disposition — risks inadvertently delivering property to the person the testator intended to exclude, by default operation of the intestacy statutes. A residuary clause in the will, or a catch-all provision in the trust, prevents this by sweeping up unallocated assets.
A no-contest clause (also called an in terrorem clause) is a provision in a will or trust that penalizes a beneficiary who contests the instrument by forfeiting what they would otherwise receive under it. California law recognizes no-contest clauses but, following a significant statutory overhaul effective January 1, 2010, substantially limits their enforceability.
Under the current statutory scheme, a no-contest clause is enforceable only against a direct contest — a pleading that alleges the invalidity of the instrument or a part of it on grounds such as lack of capacity, undue influence, fraud, duress, or forgery. It is not enforceable against:
The statutory changes, codified at Cal. Prob. Code § 21311, reflect a deliberate legislative policy choice to preserve access to the courts for meritorious challenges, even at the cost of reducing the deterrent effect of no-contest clauses.
| Person | Can Be Disinherited? | Key Rule |
|---|---|---|
| Adult child | Yes | No legal right to inherit; omit from will/trust without explanation |
| Minor child | Yes (financially) | No inheritance right, but may have separate support obligations during life |
| Parent | Yes | No legal right to inherit from an adult child |
| Sibling, other relative | Yes | No legal right to inherit |
| Prior spouse | Yes | Prior divorce severs most inheritance rights automatically; confirm deed and beneficiary designations |
| Surviving spouse (community property) | No | Owns half of community property regardless of testamentary documents |
| Surviving spouse (separate property) | Yes | Decedent may dispose of separate property to others |
| Omitted spouse (married after will executed) | Not without express language | Must include specific disinheritance language; silence treated as inadvertent omission |
| Omitted child (born/adopted after will executed) | Not without express language | Same rule; will must address post-execution children expressly |
For most potential beneficiaries — adult children, siblings, parents, other relatives — the correct approach is simply to omit them. There is no legal requirement to name someone in order to exclude them, and no obligation to explain the exclusion. A will or trust that distributes all assets to other beneficiaries, with a properly drafted residuary clause, accomplishes the disinheritance without mentioning the excluded person.
Whether to include an express disinheritance clause — “My daughter [Name] shall receive nothing under this will” — is a judgment call with considerations on both sides. Some attorneys include it to foreclose any argument that the omission was inadvertent, particularly where other children are named and the excluded person could claim they were overlooked. Others avoid it on the theory that naming the excluded person is inflammatory and more likely to provoke a contest than to deter one. The correct choice depends on the specific family circumstances and the risk profile of the situation.
For omitted heirs — a post-marriage spouse, a child born after the will was executed — an express disinheritance clause is not optional. It is legally required for the exclusion to be effective.
A will governs only probate assets — property in the decedent’s name alone, without a joint tenant or beneficiary designation. A trust governs only assets that have been transferred into the trust. Neither instrument reaches:
An effective disinheritance requires a review of every asset category. If the person to be excluded is named as a beneficiary on a retirement account or life insurance policy, changing the estate planning documents accomplishes nothing as to those assets. Beneficiary designations must be updated separately and confirmed in writing with the financial institution.
⚠️ CRITICAL ISSUE: The most common disinheritance failure is not a defect in the will or trust — it is a beneficiary designation that was never changed. A testator who disinherits an adult child through a carefully drafted trust but leaves a retirement account naming that child as beneficiary has created exactly the result they sought to avoid, for that asset.
A will or trust executed for the purpose of disinheriting someone is, by definition, a high-stakes document from the perspective of the excluded person. These are the instruments most likely to be contested on grounds of lack of testamentary capacity or undue influence. The drafting attorney should:
These precautions protect against a successful contest, which is the only tool available to the excluded person once the instrument is properly executed.
A no-contest clause operates as a conditional forfeiture: a beneficiary who receives something under the instrument but then challenges it risks losing what they would have received. The mechanism is grounded in contract-like logic — the testator’s offer of a bequest comes with a condition of non-contest.
The strategic use is obvious. A testator who disinherits one child but leaves something to the others can include a no-contest clause that operates against the favored children. If the excluded child persuades a sibling to join in a contest, the sibling risks their own bequest. This creates a structural disincentive to coalition-building among potential contestants.
It is also sometimes recommended — precisely for this reason — to leave a small bequest to the disfavored person. A person who receives nothing under the instrument has nothing to lose by contesting it; the no-contest clause has no leverage. A modest bequest gives the excluded person something at stake and makes the clause operable against them directly.
The critical limitation is Cal. Prob. Code § 21311(a)(1): a no-contest clause does not apply to a direct contest brought with probable cause. Probable cause means objectively reasonable grounds for the contest — evidence that, if believed, would support the legal theory asserted. A disgruntled beneficiary with a credible claim of undue influence can contest the instrument without triggering the forfeiture, even if they ultimately lose, so long as their grounds were not frivolous.
This exception substantially limits the practical deterrent effect of no-contest clauses in California. A well-resourced excluded person with any colorable claim — and in most contested family situations, the facts supply at least some basis for one — can challenge the instrument without personal financial risk, as long as they can articulate probable cause for the challenge.
The result, in practice, is that a no-contest clause deters only bad-faith or frivolous contests — the kind that would likely be disposed of on a motion in any event. It does not reliably deter a motivated challenger with a lawyer and a plausible theory.
⚠️ COMMON ERROR: Clients sometimes treat a no-contest clause as a primary defense against challenges to a disinheritance. Under California’s post-2010 statutory scheme, it is not. The better defense is a properly documented, carefully executed instrument with contemporaneous evidence of testamentary capacity and independent volition. A no-contest clause is a supplementary tool, not a substitute for rigorous drafting and execution.
Even setting aside the probable cause exception, California law expressly exempts several categories of proceeding from no-contest clause enforcement:
A contestant’s attorney who understands Cal. Prob. Code §§ 21310–21315 can often find a procedural path that achieves the litigation objective without technically triggering the clause.
📌 PLANNING NOTE: The strategic value of a no-contest clause today is less about legal deterrence and more about psychology. Many family members — even those with grievances — are deterred by the clause’s presence, not because they have analyzed the probable cause exception but because they do not want to risk losing their bequest. For clients whose goal is to reduce the probability of a contest without necessarily winning every contest, the clause still serves a purpose. It should simply not be relied upon as the primary mechanism of protection.
No-contest clauses in California apply equally to wills and trust instruments. Cal. Prob. Code § 21310 defines “instrument” to include both. A testator who uses a revocable living trust as the primary estate planning vehicle can include a no-contest clause in the trust, and it will be governed by the same §§ 21310–21315 framework. Because most California estate plans use a trust as the primary instrument with a pour-over will, the clause typically appears in the trust — where the substantive assets are held — and may also appear in the will for completeness.
