Yes. Washington hasn't adopted the Uniform Probate Code, but it recognizes a will validly executed under another state's law as long as the will was valid where signed. The practical wrinkle is the self-proving affidavit — if the foreign will doesn't have one, witnesses may need to testify during probate. A Washington-specific will sidesteps that. The document portability tool shows the recognition rule by document type.

Washington's execution rule for a will: 2RCW 11.12.020Verified May 1, 2026 witnesses, with notarization NoRCW 11.12.020Verified May 1, 2026. The rules apply by state statute, not by where you signed, so a document signed elsewhere still has to clear Washington's requirements when it's used here.

Washington allows Remote Online Notarization (RON) for wills and accepts notarizations performed under another state's RON authority. Practically, that means the notarization step can be completed over secure video without finding an in-person notary, and the resulting document is valid in Washington even if the notary was elsewhere.
