Washington Will Requirements
Every U.S. state writes its own rules for executing a valid last will and testament, and Washington is no exception. This 2026 guide walks through the witness count, notarization expectations, and handwritten-will rules you need to satisfy before signing — and how VoiceWill™ helps Washington residents prepare a compliant draft by voice in under an hour.
How a will is executed in Washington
Washington requires two adult witnesses to validly execute a will. Witnesses must be of legal age, mentally competent, and — in most cases — disinterested (not named as beneficiaries). notarization is optional in Washington but recommended to create a self-proving affidavit that simplifies probate.
Two witnesses required. Notarization is optional but recommended for a self-proving affidavit.
Witnesses and notarization in Washington
Choosing the right witnesses is one of the most common mistakes Washington residents make. A beneficiary witness can invalidate a bequest in many states. Washington attorneys generally recommend two clearly disinterested adults sign at the same time, in the testator's presence, and in each other's presence.
A self-proving affidavit is a short notarized statement attached to the will. It is not the will itself — it allows Washington probate courts to admit the will without calling the witnesses back to testify, which saves time and cost during probate.

What Washington probate looks like
When a Washington resident dies with a will, the executor files it in the probate court of the county where the decedent lived. The court validates the will, supervises the executor, and oversees distribution. Small estates may qualify for a simplified or affidavit-based process; larger or contested estates can take 6–18 months.
A living trust is the most common way Washington families bypass probate for major assets. VoiceWill™ can draft a coordinated will and revocable trust together so nothing is missed.
Healthcare directive and power of attorney in Washington
A will only takes effect at death. Two other documents protect you while alive: a Washington advance healthcare directive (also called a living will or healthcare proxy) names who makes medical decisions if you cannot, and a Washington durable power of attorney names who manages your finances during incapacity. Most Washington estate plans need all three.
Choosing executors and guardians in Washington
Your executor must be an adult Washington resident or, for non-residents, generally a close relative — confirm your county's rules. Name at least one alternate. If you have minor children, your will is the place to nominate a guardian; Washington courts give strong weight to a parent's nomination but make the final call based on the child's best interests.
