Can a Dealer repo my car for not paying down payment?

I am in a Bankruptcy 7 getting ready to be discharged. Needed a vehicle so I went to a Bad credit place. They told me I could have a vehicle with 1000 down and could defer it for a few weeks. I did the paperwork and a few days later the dealer called and said I couldn't do it but if I had someone else get the loan in their name then I could transfer the loan back to me after the discharge went through. So I had a family member do it and I have the car. It is now 40 days later and I have not given a down payment and the car has been funded from the finance company for a few weeks. I am wondering if because of the switch of person obtaining the loan the deposit went unnoticed. No one had my family member sign any paperwork on the deposit and all my paperwork was thrown out (I was told by an associate. Can the dealer repo my car if they realize there was no deposit made?
