I believe whoever has the title or if the title is still in your name, then yes you may take the car back. You may want to ask for sheriff back-up if there are any problems. Or just key the ignition and take-off, if you can. Some state laws may differ.
potentially, yes; consult a lawyer
Yes, your car can be repossessed in any state if your contract was signed in Chicago. You can not move to a different state and keep your car without paying for it.
No one can take money out of your account without a court order. The exception being payments to the bank itself for administration purposes or penalties. These, however, would be set out in the initial contract.
Read that letter carefully. The one that I am most familiar with clearly states that you have 20 days to make any past due payments and if they are paid you may continue with the original contract, BUT if you become delinquent again, they may exercise their rights without giving you any additional notice. That means from now on you had better not miss any payments, not even by one day, or your car could be repossessed.
The time your contract says. If once a week or once a month. Read the contract or bend over.
IF the loan is perfected, it can be repossessed. If you have signed a loan contract with the vehicle specified as collateral for that loan, it can be reepossessed if the loan is in default.
Your car can be repossessed at any time without any warning if you aren't making your payments. It is probably in your paperwork in the fine print what happens when you don't make your payment.
The length of time that a car payment can be late without being repossessed will depend on the bank or car dealers agreements. Payments made after a month may be in jeopardy of being repossessed.
Only if there is a "Right To Repossess" document or a contract that states a "time sensitive" payment schedule. Without either, repossession is next to impossible without a Civil Court hearing! Y-THINK-Y * Yes, Texas Business and Commerce Code Right To Possession Without Breach of Peace using non-judicial means, (Chapter 9, Section 9.503).
YES, very much so. If you cant get out of default, get your stuff out of the car.
If you have no lien on your vehicle then no one has a legal right to repossess it. If you're not behind on the payments there would be no reason for the lender to reprocess the car in the first place. It is hard to believe you have a loan on a car without a lien. The car stands behind the loan. If there's no lien on the vehicle then the car is not involved in the loan and cannot be repossessed.
READ your contract you signed. Call a local attorney for state specific legal advice.
