Unfortunately, it does not matter that you never owned or possessed the car personally--if you were a signor or co-signor on the lease or financing for the car, you are liable for it. The law does not care who actually made use of or drove the car; it only cares about who agreed to be financially responsible of liable for it, which you did. The lender or its collections agency can come after you for the money, and if you don't pay, can sue you; your credit will also be damaged.However, if there was another signatory--and especially if that person was the one who actually received the use and benefit of the car--you should be able to sue him or her to recover money. You would sue for breach of contract (violation of the lease or financing agreement, which obligated the co-signor as well as you to pay; also, violation of any agreement between the two of you as to who would pay), and also potentially unjust enrichment (they got the benefit of the car without paying) and/or promissory estoppel (if you only signed becaue of their promise to pay, that sometimes is enough to make the promise enforceable even in the absence of an actual agreement between the two of you). Therefore, you may be entitled to compensation and should consult with an attorney to explore your options in greater detail.In the future, do NOT cosign loans, leases, or financing of any kind for anyone, except possibly for college for your children--you assume as much risk as if you were taking out the loan, etc. yourself.
