I'm the co owner of my car and my moms the main owner. I want to sell it but I don't know how.?

Technically it is your mothers car.

Her name on the title is the Technicality that makes it her car.

She will need to sign the title, and in some states the signature must be notarized. She may also have to fill out a form and sign it depending on what state you are in. She does not have to be present when you sell the car or transfer the title, but you will need her signatures on the paper work.

Depends on how the wording on the title reads.

If it reads your Mom's name and or your name then only one of you has to sign. If however it reads your Mom's name and your name then both signatures are required.

Good luck.

if there are TWO names on the title, it requires TWO signatures to transfer ownership. Get mom to sign the title over and then you can sell the car to your friend. Remember, the financing MUST be paid off to transfer, unless the buyer agrees to assume the remaining balance of the loan. The lender also has to agree to transfer financing or you MUST pay off in full to clear the lien the lender has on the title.

It might be in reality your car, but technically (legally) it's both yours and your mothers. She needs to sign off on the title and Bill of Sale to the buyer.

If her name is on the document(s), you are required to have her sign, too.

if the title says "and" you need her signature.

if it says "or" you do not.
