Selling a trailer in Washington: what to know
Washington runs trailers through the Department of Licensing with a firm calendar: after a private sale the buyer has 15 days to transfer, and penalties start on day sixteen. Trailers over 2,000 lbs are titled; lighter intermittent-use utility trailers skip the title but still need license and registration for public roads.
Washington also has an official bill of sale form (TD-420-065, Vehicle/Vessel Bill of Sale) used for tax and licensing, and title applications are signed in front of a licensing agent or notary at the counter. Bring the signed-over title (if titled), the bill of sale showing the price, and ID.
