"Surrendering" your car means that you give it back to the lender that you financed it with. If you surrender your car, any debt that you owe on it will be forgiven when you receive your bankruptcy discharge.
If you would like to surrender your car, you must:
let the bankruptcy court and the lender know on your Statement of Intentions,
wait for the court to authorize the lender to repossess the car, and then
make the car available for the lender to repossess. They can either come and get it from you or you can bring it to them at an agreed location. There is no hard and fast rule, but most creditors will try to repossess the car a few weeks after the court authorizes them to do so.
