How to fill out Washington 420-040

Two forms printed on one sheet, and a seller may need either or both. The upper half swears that a document - the title, the registration, a tab, a decal, the plates or a metal tag - is gone. The lower half releases interest in the vehicle without using the certificate. Both halves are signed under penalty of perjury and both must be notarised or certified, which is the difference between this and signing the certificate itself.

Written against 420-040 (R/3/18), issued under RCW 46.12.580 and WAC 308-56A-265. The two halves look alike and are not interchangeable. Swearing that a title is lost does not release your interest in the vehicle, and releasing your interest does not tell the department the certificate is missing - a sale where the certificate never turned up usually needs both halves completed by the same person on the same sheet.

Two documents, and they are not the same thing. Take the blank 420-040 from the dol.wa.gov copy so you get the revision that is current today.

Filled in

What a completed one looks like

This is the actual 420-040, 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 Affidavit of Loss/Release of Interest, form 420-040, for a 2015 Toyota RAV4: the plate and identification numbers, the title box ticked in the affidavit of loss with lost ticked as the reason, Rosalind Vandermeer of Spokane named and signed with the date and place, the ownership box ticked in the release of interest half with her signature again, and the single seal block at the foot left blank for whoever witnesses both.
Both halves completed by the same person on the same sheet, which is what a sale with a missing certificate actually needs. The second name column on each half has been left grey - it is there for a jointly owned vehicle, and on a single-owner car it stays empty.
Field by field

Every line, in the order you meet it

  1. 1
    You fill this in

    The vehicle band

    Plate or registration number, identification number, model year, make, model and body style.

    Watch out: One band serves both halves of the sheet. Fill it in once and it covers whichever half or halves you go on to complete.

  2. 2
    You fill this in

    What you do not have

    Six ticks: title, registration, tab, decal, plates, metal tag. Check all that apply.

    Watch out: Tick everything that is genuinely missing. Coming back a fortnight later because the tabs went with the title is a second notarised affidavit and a second fee.

  3. 3
    You fill this in

    Why you do not have it

    Destroyed, illegible, lost, stolen, or defaced and can no longer be used.

    Watch out: Stolen is a different answer from lost and the department reads it differently - a stolen certificate is a fraud risk, and saying so is what puts a flag on the record.

  4. 4
    You fill this in

    Your details, printed

    Name, position and company if signing for a business, telephone, Washington driver licence number and email.

    Watch out: The name has to match the certificate the department holds. If you have married or changed name since, that needs sorting out first or the affidavit swears about somebody else's document.

  5. 5
    You fill this in

    Date, place, and the signature you must not make yet

    The date, the city or county, and the signature line - which prints its own instruction to sign before a notary or vehicle licensing agent.

    Watch out: Signing at home and posting it is the single commonest way this form comes back. The department will accept a posted form only if the signature on it was notarised.

  6. 6
    You fill this in

    The release of interest half

    Three ticks - ownership, gross weight licence, personalised plate - then the same name and signature structure again.

    Watch out: Ownership is the tick that matters in a sale. The other two exist for a seller keeping a personalised plate or dropping a weight endorsement.

  7. 7
    You fill this in

    The notarisation block at the foot

    One seal block at the very bottom of the sheet, carrying the place and the date, the names of everybody who signed in front of the witness, and the witness's signature, printed name, title and number.

    Watch out: One block covers both halves and everybody who signed in front of that person. A co-owner who was not there is not covered by it.
