Illinois Vehicle Power of Attorney (Form RT 5.10)


An Illinois motor vehicle power of attorney (Form RT 5.10) authorizes a person (the attorney-in-fact) to represent the creator of the document (the vehicle owner) while performing specific tasks. When acting on behalf of the vehicle owner, the attorney-in-fact must present a copy of the form to the car buyer, seller, business, or Department of Motor Vehicles (DMV).

Signing requirements: Vehicle owner signature mandatory.

What is an Illinois Motor Vehicle POA?

An Illinois motor vehicle power of attorney discloses how and when a car owner wants tasks carried out by another person. The document’s creator must use precise and clear language to properly inform the attorney-in-fact of the duties that need completing. Furthermore, it prevents the appointed individual from overexercising their power.

Setting an expiration date is another step that an owner can take to ensure the attorney-in-fact does not abuse their decision-making power. Upon creating a revocation form, the principal cancels existing limited power of attorney forms (and all copies), thus causing the assigned person to lose their authority.
