A Washington vehicle power of attorney, or ‘Form TD-420-050’, can be utilized to designate another person to handle vehicle registration and title with the Washington State Dept. of Licensing (DOL). When properly filled out and submitted, this paperwork will allow the agent to perform actions with your vehicle such as securing, or releasing, a Washington title and/or registration. Only the principal vehicle owner or someone with the power to represent this entity can deliver this type of power over a vehicle. Similarly, only the principal vehicle owner who has issued this document and approved an agent’s use of his or her name can revoke this paperwork (in writing). Both actions can be performed at the discretion of the principal.
