What are the legal requirements for a valid will?

On Behalf of | Aug 12, 2025 | Estate Planning |

Creating a legally valid will ensures that your wishes regarding asset distribution will be followed after your death. In Washington State, specific legal requirements exist to ensure the validity and enforceability of a will. Understanding these requirements is crucial to avoid confusion or disputes among heirs and beneficiaries.

The will must be in writing

Washington law requires a valid will to be in writing. This can either be a handwritten (holographic) will or a typed (formal) will. Oral wills do not meet the legal requirements and hold no validity. Therefore, you must put your intentions in writing to ensure others can honor them after your death.

The testator must be at least 18 years old

To create a valid will, you must be at least 18 years old. Additionally, you must be of sound mind when executing the will. This means you must have the mental capacity to understand your property, identify your beneficiaries, and recognize the effect of the decisions you make in your will.

The will must be signed by the testator

You must sign your will at the end of the document for it to be legally binding. Your signature demonstrates your agreement with the contents of the will and affirms that it accurately reflects your intentions. If you cannot sign, someone may sign on your behalf, but they must do so in your presence and at your direction.

The will must be witnessed by two individuals

State law requires that two individuals witness your will, and they must be at least 18 years old. The witnesses cannot be beneficiaries named in the will. They must observe you signing the will and then sign it themselves. This confirms that you signed the will voluntarily and that you possessed sound mind when doing so. Although witnesses don’t need to know the contents of the will, they must affirm its execution was voluntary.

No undue influence or coercion

Your will must represent your genuine intent and should not result from coercion or undue influence from others. If someone pressures you into making changes to your will or forces you to name certain individuals as beneficiaries, a court may invalidate the will due to lack of voluntary consent.

To ensure your will meets the legal requirements, you must follow specific guidelines. By complying with these stipulations, you can safeguard your wishes and protect your loved ones from potential complications.
