If a husband's name is the only one on the lease, then he is the sole owner of the vehicle and the only person who can legally drive it. His wife may be able to drive the vehicle with his permission, but she will not have any legal ownership rights to the car.
If the wife wants to have legal ownership of the vehicle, she will need to be added to the lease. This can be done by contacting the leasing company and requesting to have her added as a co-lessee. Once she is added to the lease, she will be jointly responsible for the lease payments and other costs associated with the vehicle.
It is important to note that adding someone to a lease can affect the terms of the lease, such as the interest rate and the monthly payment. It is important to carefully review the lease agreement before adding anyone to the lease.
