What happens with your car will be dependent upon the circumstances. The value of the car will be particularly important; it may be necessary to instruct a valuer or the value could be mutually agreed. Consideration should also be given as to whether there are any liabilities held against the car, reducing the value of your interest.
Regardless of who is the legal owner of the car, it will be an asset available for distribution when resolving financial matters and the value will be taken into account when considering the overall division of assets.
