question about new car

Ok, my husband is going through the beginning stages of debt settlement, it's been about 40 days since last paying bills. I am his wife, all the bills were in his name. I lease a car, my lease is up and I got preapproved for new lease since I was such a good customer. We just found out his name was on my lease as colessee, we both no idea that he was on the lease until now. Now the problem, my preappproval for the new car is only WITH him as colessee. I know I am the primary on the car, but will this ruin his chances for settlement if he does this with me?? Any advice would be great. I will admit this car is an infiniti, which payment wise was the same as my nissan. the payment is 640. I look forward to any advice you can shed.
