When can a will be contested in Washington state?

On Behalf of | Mar 27, 2025 | Probate

A will should reflect a person’s final wishes. The terms are not for anyone other than the testator to dictate. 

Unfortunately, disputes over a will can arise. In Washington state, a will can be challenged in court under specific circumstances. Here are some of the most common grounds for will contests

Lack of testamentary capacity

A will can be contested if the testator was not of sound mind when they made it. In Washington, the testator must understand:

  • The nature of making a will.
  • The extent of their assets. 
  • Who their beneficiaries are.
  • How the will distributes assets. 

If the testator had dementia or another condition that impaired their judgment, the will may be invalid.

Undue influence or fraud

A will may also be challenged if someone inappropriately pressured or manipulated the testator. This is known as undue influence. It often happens when a caregiver, family member or friend isolates the testator to control their decisions.

Fraud is another valid reason for contesting a will. If someone tricked or misled the testator into signing a will, it may be overturned in court.

Improper execution

Washington law requires wills to meet certain formalities. The will must be:

  • In writing. 
  • Signed by the testator. 
  • Witnessed by two people who are not beneficiaries. 

If these steps are not followed, the will may be legally invalid.

In Washington, a will contest must be filed in superior court within four months of probate being opened. Contesting a will is complex, but knowing the legal grounds can help you understand your options. Seeking further guidance can also be highly beneficial.
