Will Washington courts enforce your will’s no-contest clause?

You might add a no-contest clause to your will, expecting it to keep relatives from quarreling over your estate after you pass away. Understanding how the courts view these provisions can help you weigh whether it belongs in your plan.

Defining the no-contest clause

A no-contest clause, sometimes called an in terrorem clause, penalizes a beneficiary who challenges your will and loses in court. The penalty usually reduces or erases the inheritance that person would otherwise have received.

Its purpose is to discourage litigation by raising the cost of a failed challenge. A relative who might otherwise contest the document could reconsider once a defeat threatens to leave them with almost nothing.

Examining the state’s controlling standard

Washington courts generally respect no-contest clauses, yet they decline to treat enforcement as automatic in any given case. Each dispute receives a review on its own facts rather than through a single fixed rule.

The provision cannot compel forfeiture when a beneficiary pursues a challenge the law independently protects. The court considers whether the contest was brought in good faith and with probable cause, meaning the beneficiary must have both a sincere concern and reasonable, objective legal grounds for the challenge.

Provisions that collide with public policy likewise tend to lose their force once scrutinized. Terms meant to punish a beneficiary for raising an issue the law treats as legitimate may not withstand review.

Applying the probable cause exception

The most consequential boundary is the probable cause exception. This exists when enough evidence would lead a sensible person to conclude the challenge stands a meaningful chance of success.

Suspicions of forgery, undue influence, fraud or a lack of mental capacity can each supply that foundation. The strength of the proof often matters as much as the category of the claim.

Washington courts have also recognized that reliance on an attorney can reinforce a finding of probable cause. A beneficiary who candidly presents the facts to counsel and then follows that advice generally stands on steadier footing.

Drafting enforceable language

Because the outcome heavily relies on the facts, the wording of your clause carries considerable weight. Language that clearly defines what amounts to a contest leaves a court less room to second-guess the intent you expressed.

A carefully written terms also accounts for the exceptions the law already builds in. Combining that care with candid conversations among your heirs can reduce the chance that anyone feels blindsided enough to pursue litigation.
