Have been separated from my wife 12 months now,since we split I have brought a new car just wondering if she has any claims to the car and if so can I get around it.

Are you legally separated, with a legal paper registed with the court?

If not, while not likely, she can try, since you are legally married still

Thanks for your response,not legally ,but we have a parential plan in place throu the courts

Move on with the divorce before it gets too complicated,

Depends on what state you reside in. I live in Ohio. I can tell you that in Ohio she can still attempt to take the vehicle since you are legally married. Worse case, she takes the vehicle and you are mandated to make the payments. It has happened but it depends on your divorce rules in your state. I would contact and attorney so you are protected through this. I purchased my vehicle while separated but got paperwork through my attorney and signed by her to release her rights to it. Basically like a contract.
