Are no-contest clauses in trusts enforceable?
Yes, but only in the three situations Probate Code section 21311 lists. Most people who hold back because of a no-contest clause are more protected than they think: the clause cannot touch a contest brought with probable cause.
| What you file | Can the clause be enforced? |
|---|---|
| A direct contest of the will or trust with probable cause | No |
| A direct contest without probable cause | Yes |
| A claim that property in the trust or estate was not the transferor’s | Only if the clause expressly says so |
| A creditor’s claim against the estate or trust | Only if the clause expressly says so |
What is probable cause to contest a trust?
Probable cause exists if, when you file, the facts you know would cause a reasonable person to believe there is a reasonable likelihood the court will grant the relief you ask for after further investigation or discovery (Probate Code section 21311). You do not need to be certain you will win.
An example with probable cause
Your father amended his trust two weeks before he died to leave everything to a new caregiver. His medical chart from that month records advanced dementia, and the caregiver arranged the lawyer. A reasonable person would expect discovery to support an undue influence claim.
An example without it
Your mother left more to your sister because your sister cared for her for ten years. You have no evidence your mother was confused or pressured; you simply think the split is unfair. Unfairness alone is not a ground to contest, so a contest here risks triggering the clause.
What does not trigger a no-contest clause?
Anything that does not claim the will or trust is invalid. Asking a trustee for an accounting, petitioning to remove a trustee for misconduct, or asking the court to interpret an unclear term are generally not contests, because they enforce the document rather than attack it.
California also construes these clauses strictly, so a clause is not stretched beyond what it actually says (Probate Code section 21312).
What do you lose if a no-contest clause is enforced?
Whatever the clause says you forfeit, which is usually everything you would have received under the document. That is why the probable cause question should be answered before you file, not after.
Can you contest a trust if you are not a beneficiary?
A no-contest clause can only take away a gift. If you receive nothing under the trust, the clause has nothing to take from you, though you still need standing to bring the contest. See how to contest a trust.
How do you write a no-contest clause that works?
Be specific about which documents it protects and what it covers, and leave the likely challenger enough to lose. A clause cannot deter someone who would receive nothing anyway, and it will not stop a contest brought with probable cause.
- Name the instruments it protects: the trust, every amendment, the pour-over will.
- Say expressly whether it covers ownership challenges and creditor claims. Without that language it does not (Probate Code section 21311).
- Make your capacity and independence easy to prove: a lawyer of your own choosing, no beneficiary in the room, and a clear explanation of why the plan is uneven.
- Review it when you amend the trust. A clause written for one document does not automatically cover later ones.
An illustration only, not a form to copy: “If any beneficiary brings a direct contest of this trust or any amendment to it without probable cause, every gift to that beneficiary under this trust is revoked and shall pass as if that beneficiary had died before me.” A people-also-search topic is a will no-contest clause example; the same structure is used in wills.
