Do you need a Chapter 13 case? WHEN you file it can mean the difference between a payment plan that takes 3 years and one that takes 5.
You can keep your leased vehicle under Chapter 7 if you're current. If not, or have other reasons to do a Chapter 13 case, that works too.
Chapter 7 gets you out of a vehicle lease owing nothing. Chapter 13 is more complicated but can give you pretty much the same good result.
