In GA Can you get your car back after a repossession if you file chapter 13 bankruptcy
A car is not totaled in a chapter 13. A car may be totaled while the owner is in a chapter 13. If the car was fully exempted, nothing happens. If you need to buy a new car, you will have to get permission from the bankruptcy court after you file a specific purchase agreement (car loan) which should not seriously affect your plan payments. Why are you not asking your lawyer?
if your chapter 13 gets dismissed can you buy a car
No.
It is up to the creditor to file a motion for relief from stay in order to take back the car. Your ability to buy another car will only be limited by your ability to find a willing seller and a willing lender.
If you file bankruptcy and you have not been discharged the car that you buy can be used to finance it.
If you wreck your car after filing for Chapter 13 bankruptcy you can file it on your insurance. You can then replace your car based on the bankruptcy order.
I have file for Chapter 7 twice and it has had no effect on my car insurance.
Yes.
You only get the car back if you file for Chapter 13 before the bank auctions off the vehicle. If you file for Chapter 13 before the auction, the bank should turn over the property right away. If the bank won't cooperate, you may need to file a formal motion with the bankruptcy judge for a turnover order. The time to have the motion heard will depencd on the Court's workload, perhaps 4-6 weeks.
The day you are discharged you can buy a car. You need to take proof that you are discharged.
