Will my car be taken if my cosigner dies?
Not as long as you make your payments on time. A co-signer guarantees that you will pay your loan off. If your co-signer dies and you don't make your payments the lender will repossess the car and go after you for any deficiencies.
If you are late on your loan payment and are a cosigner on your daughters car can they repposses the car?
My sympathies to you and your family. If you, your husband or anyone else in the family didn't cosign for a loan for the car then the debt ends. If there was a cosigner then the cosigner is responsible for the debt. If your son was not a minor and took the loan out himself and he has left a Will or has anything of value this debt will be paid off or written off.
