Can owner confiscate car from co owner? And/Or vice versa?

So About a week ago my mother helped me to buy a new car (2008 Honda coupe) and the agreement was that I'd pay her back half of the cost of the car (this isn't written in stone so its more a verbal agreement). Now I signed as the co owner of the vehicle until my half of my debit is paid. Now my mother also owns an older 2002 honda coupe, that my name isn't on just hers. Earlier this year while i was in college i ran a red light and we're just now finind out about that ticket which is under her name. I offered to pay it but she was more concerned with getting points on her license, so she took my eyes and confiscated the car. Is there anything I can do I hate to say it but i don't wanna have to take my own mother to court over a speeding ticket that i was unaware of until just last night. But i feel like there's something that can be done. Is there a way to handle this without getting the law involved. I just wanna make sure i'm not wrong on this one so i can get my car back. Plus i haven't made my first payment to start paying off the 2008 yet. Any help/ legal advise would be greatly appreciated.

(btw the ticket was obtained in md, and the new car was bought in va since i know state jusrisdiction matters)

She has the same rights to the car as you do.

What do you mean co-owner? Who's name is on the title? If her name is on the title, she can take the car anytime she wants. Regardless of whatever verbal agreement you had about paying for it.

The fact that a red light camera sent her the ticket makes it sound like she is the registered owner, not you.

The ticket is irrelevant for ownership. If only her name is on the title, then only her name will be on the registration. If that is true, she owns the car.

If your name is on the registration, that means that your name is on the title, which means that you own the car, and it is your property that she can't seize.

If the car is only in her name, then the loan is only in her name, and if you stop paying it, the lender will sue her and repossess the car from her. Her credit will be damaged, not yours.

If both your names are on the registration, that means both your names are on the title, and you both have the same right to use the car.

If you own the car, you have a legal right to it.
