If you have been researching living trusts, you may have come across a provision people casually call a “no arguing clause.” In plain English, it says: if you challenge this trust and lose, you give up whatever you were set to inherit. Attorneys know it by more formal names, a no-contest clause, an in terrorem clause (Latin for “in fear”), or a forfeiture clause, but the purpose is the same. It is designed to discourage beneficiaries from dragging a family estate into court after the person who created the trust has passed away.
Here is a plain-language look at what these clauses do, how they hold up under Colorado law, and when they make sense in a living trust.
What a No Arguing Clause Actually Is
A no arguing clause is a condition attached to a gift. Rather than leaving property to a beneficiary with no strings attached, the trust makes the gift contingent on the beneficiary not attacking the trust. If the beneficiary accepts the inheritance, they keep it. If they file a lawsuit seeking to invalidate the trust and that challenge fails, the clause typically treats them as if they had died before the trust’s creator. Their share is forfeited and passes to someone else.
The key word is deterrence. A no arguing clause cannot physically stop anyone from suing; nothing in a trust can do that. What it does is raise the stakes. A beneficiary considering a challenge must weigh the possibility of walking away with nothing against whatever they hope to gain.
How It Works in a Living Trust
A living trust, also called a revocable trust, is created during your lifetime. You usually serve as your own trustee, keep full control of your assets, and can change or cancel the trust whenever you like. When you die, the trust becomes irrevocable, and a successor trustee steps in to distribute your assets according to its terms.
This is where the no arguing clause becomes relevant. Because a properly funded living trust passes assets outside of probate, distribution is generally private and faster than a will that must go through court. A disappointed beneficiary who wants to upset that plan must file their own lawsuit to contest the trust, and the clause sits inside the document as a built-in penalty aimed at anyone who does.
Colorado also imposes a firm deadline on trust contests. A challenge to a revocable trust must generally be brought within three years of the creator’s death or within 120 days after the trustee sends the beneficiary a copy of the trust with notice of its existence, whichever comes first.
Are No-Contest Clauses Enforceable in Colorado?
Yes, with one important limit. Like most states, Colorado recognizes and will enforce no-contest clauses. Colorado’s probate statutes state that a provision penalizing someone for contesting a will or bringing related proceedings is unenforceable if probable cause existed for doing so. While that rule is written for wills, Colorado courts have applied the same reasoning to trusts.
Courts here also construe these clauses strictly, with a strong preference for avoiding forfeiture wherever possible. The practical takeaway: a no arguing clause in a Colorado living trust is generally valid, but a court will read it narrowly and will not enforce it against a beneficiary who had a legitimate, well-supported reason to sue.
The Probable Cause Exception
The probable cause is the heart of the matter. Colorado courts have described it as evidence, existing when the case is filed, that would lead a reasonable and properly informed person to conclude there is a substantial likelihood the challenge will succeed.
In everyday terms, if a beneficiary sues because they reasonably believe, based on real evidence, that the trust was the product of fraud, undue influence, or a lack of mental capacity, a Colorado court will likely refuse to enforce the forfeiture even if that beneficiary ultimately loses. One factor courts weigh is whether the beneficiary sought the opinion of independent counsel in good faith before filing. By contrast, a beneficiary who sues out of spite or on a hunch, with no meaningful evidence, risks triggering the clause and losing everything.
What Usually Does Not Trigger the Clause
Because courts read these clauses narrowly, not every trip to the courthouse counts as a contest. The following actions generally do not amount to an attack that triggers forfeiture:
- Requesting an accounting or information from the trustee
- Asking a court to interpret an ambiguous term rather than challenging the trust’s validity
- Asserting a legal right you already hold
- Holding a trustee accountable for misconduct, such as self-dealing or mismanagement
The distinction is between attacking the trust itself and enforcing or clarifying it. Still, much depends on how the specific clause is written.
Why Colorado Families Include One
No arguing clauses tend to appear where a challenge is foreseeable:
- Unequal distributions, where heirs receiving less may feel slighted
- Blended families with second marriages and stepchildren
- A history of family friction over money
- A desire to protect privacy and preserve the estate from litigation costs
Limitations to Understand
A no arguing clause is a useful tool, not a magic shield. The beneficiary must have something meaningful to lose; if you disinherit someone entirely, they risk nothing by suing. The clause is a deterrent, not a guarantee, and the probable cause exception means a well-founded claim can survive it.
Work With an Experienced Colorado Estate Planning Attorney
Whether a no arguing clause protects your legacy or simply provides false comfort almost always comes down to drafting: who it covers, what conduct it targets, and whether a potential challenger is left enough to make the threat real. Because Colorado applies a probable cause exception and reads these clauses strictly, generic online-form language often falls short. An experienced Colorado trust attorney can evaluate your family dynamics, tailor the clause to your goals, and ensure it fits alongside the rest of your plan. If your existing trust already contains one, having it reviewed is a worthwhile step toward making sure your wishes, not a courtroom, decide how your estate is shared.
