How to fill out Washington 420-043

The shortest form in the Washington set and one of the most useful. Its whole instruction is a single line - use this form to make a statement of fact - and it exists because rule 308-56A-215 lets the department require an affidavit explaining any erasure or alteration on a certificate, an application or a supporting document. When something on the paperwork does not match and there is no dedicated form for it, this is the one.

Written against 420-043 (R/7/26), issued under RCW 46.12.530 and WAC 308-56A-215. There is no notarisation block on this form, which makes it the exception in a set where almost everything else carries one. That is not an invitation to be casual with it - it is signed under penalty of perjury, and the department is entitled to weigh what it says against what the rest of the paperwork shows.

Two documents, and they are not the same thing. Take the blank 420-043 from the dol.wa.gov copy so you get the revision that is current today.

What a completed one looks like

This is the actual 420-043, rendered from the PDF the Washington State Department of Licensing publishes and completed end to end: letterhead, every field, and the blocks at the foot.

A completed Washington Certificate of Fact, form 420-043, for a 2015 Toyota RAV4: plate BKT4192, the vehicle identification number, model year, make and model, a written statement explaining that the certificate was issued in a former married name, and the signature, date and place signed at the foot.
Three steps and a blank block, filled in. The statement in the middle is the whole document, and it is worth writing it as though a stranger will read it out of context - because that is exactly what happens to it.
Field by field

Every line, in the order you meet it

  1. 1
    You fill this in

    Plate or registration number

    The first box of step one.

    Watch out: If the vehicle has no plate any more - scrapped, or the plates already surrendered - the registration number goes here instead, and the department can match on it.

  2. 2
    You fill this in

    The identification number

    The vehicle identification number, or the hull number for a boat.

    Watch out: Take it from the certificate. A statement of fact that carries a different identification number from the record it is meant to explain will not be attached to anything.

  3. 3
    You fill this in

    Model year, make and model

    Three boxes completing step one.

    Watch out: Use the department's description rather than the manufacturer's marketing name, so the form reads consistently with the record it is about.

  4. 4
    You fill this in

    I certify that

    One open block, which is the entire point of the form.

    Watch out: Write the fact, the date it happened and the document it affects. A certificate of fact that does not name the document it is explaining leaves the agent to guess.

  5. 5
    You fill this in

    Printed name

    Your name, typed or printed, above the perjury declaration.

    Watch out: The name here should be the one on the certificate you are explaining - even if that name is the thing you are explaining.

  6. 6
    You fill this in

    Signature, date and place

    Print the form, sign it, then the date and the city or county.

    Watch out: There is no notary block on this one, so the place-signed box carries more weight than usual: it is what makes this a declaration under the law of Washington.

What gets this one rejected

Rules that decide whether it is accepted

Every line here was read off 420-043 (R/7/26) itself — the PDF is here — and off the Washington State Department of Licensing pages. This is plain-language help with a form, not legal advice, and where our wording and the agency's differ, theirs governs.
