What a No-Contest Clause Does
A no-contest clause, sometimes called an in terrorem clause, is a provision that says: if you challenge this will and lose, you forfeit your inheritance. It is a deterrent. The goal is to discourage beneficiaries from tying up the estate in litigation.
These clauses are common in situations where a testator expects conflict. Perhaps one child receives more than the others. Perhaps a family member was intentionally left out. The no-contest clause gives beneficiaries a reason to accept the will as written.
A provision in a will purporting to penalize an interested person for contesting the will or instituting other proceedings or actions relating to the estate is unenforceable if probable cause exists for the contest, proceedings or actions.
A.R.S. § 14-2517The Probable Cause Exception
Under Arizona law, no-contest clauses do not have unlimited power. If the person contesting the will had probable cause, meaning a reasonable basis for believing the challenge had merit, the penalty clause cannot be enforced against them.
This protects people who raise legitimate concerns about fraud, undue influence, or lack of testamentary capacity. There must be a substantial likelihood that the facts support the challenge.
The standard is not whether the challenge succeeds. It is whether reasonable grounds existed to bring it. A beneficiary who suspects the testator was pressured into changing their will shortly before death would likely meet this threshold. This is true even if the court ultimately upholds the will.
Strengthening the Clause
For families where conflict is a real possibility, pairing a no-contest clause with clear documentation of the testator's intent and capacity can strengthen the clause's deterrent effect. When the record shows the testator made informed, independent decisions, it becomes harder for anyone to claim probable cause.
Some families record a video of the will signing or have the testator's physician provide a capacity letter. These steps do not guarantee the clause will hold, but they raise the bar for anyone considering a challenge.
Understanding how this statute works helps families plan more effectively. A no-contest clause is a useful tool, but it works best as part of a broader strategy that includes clear documentation and open communication about the testator's wishes.
