Only if you have written permission from the lienholder.
Your question makes no sense. There is no lien on you but only on your vehicle. You do not file a lien release unless you have a "release of lien" issued by the financial institution which you borrowed money from against that vehicle. If there is a second lien "mechanics lien, tax lien, etc." that lien now becomes primary. Another person cannot take possession and or register the vehicle in their name until any and all liens have been satisfied. 19 years experience in the car biz.
Take the title to the office where you get your tag at, and take the buyer, and the lien holder and the'll help you.
Best practices dictate that you take the lien filed against the vehicle to an association-savvy attorney and request guidance.
You must talk to the lender who has a lien on the vehicle. It is up to them if you will be allowed to take over the payments.
You would not usually "file" the mechanic's lien, which arises by law when you repair a vehicle. You can sue the vehicle owner and take and sell the vehicle in the legal process.
The lien is still valid, even though you purchased the vehicle through a dealership. The lienholder's name should be on the vehicle title, though. If you were not notified of the lien before buying the vehicle, see the dealership and ask for "rescission of contract"--this means the dealership will take back the vehicle and refund your money. If the dealership is unwilling or unable to do so, contact you state's attorney general.
While I am not familiar with this "30 day hold," but the lien holder of a vehicle may take possession of the vehicle at any time after the loan has been defaulted. That is if you the borrower go delinquent on payments, and the vehicle is impounded (potentially for parking violations or excess unpaid tickets), the lien holder will receive notice. Actually they receive notice of impound even if you are not delinquent. If the lien holder pays the outstanding impound and storage fees, they may take possession of the vehicle.
Eventually the state will auction it off to recoup their costs. If you have a lien on it currently, the lien holder may take it out of impound and auction it - the state recovering their costs takes priority over the lien holder, and the lien holder will lose all claim to the vehicle if the state auctions it off. Either way, the payments for the vehicle will remain your responsibility.
Best way to do it is let the professionals take care of that part. Contact them, show them the title and the lien to the vehicle, and let them do their thing.
A subordination agreement is usually used to gain consent from one lien holder to take a junior position to another lien holder. It isn't by itself a mortgage or a lien.
You transfer the title to new owner. However, if there is a lien on the vehicle it must be paid off first. Check your state DMV.
Yes, the bank has the right to repossess the vehicle if you are in arrears on payments.
