Unfortunately for one that needs a lien release from a company no longer in business one will have to obtain a lawyer. The liens from the original holder usually become assets to the companies they owed.
Yes--as to that lienholder's lien only.
No
You will need to pay off the lien first, or arrange with the lienholder to be able to make a sale.
The property is subject to a lien. The question isn't whether you can sell it. The problem is that the buyer won't buy the property as long as there's a lien on it. Your attorney will need to negotiate a partial release or a full release with the lienholder if you will pay off the lien, or half of the lien, out of the proceeds from the sale of the 20 acres. If you don't pay the lien in full and the lienholder agrees to a partial payment then the lien will still be an encumbrance on your remaining property.
You request it from the DMV of the state you have it registered in. If they haven't received notification from the lienholder, then you need to contact the lienholder and have them rectify this.
A blanket lien is a lien which gives the lienholder the entitlement to take possession of any or all of the lienee's real property to cover a delinquent loan.
That is the only way you can repossess a vehicle. Repossession comes under the UCC which grants a lienholder the right to repossess but only if they have perfected their lien by filing it on the title. One caveate is in most states the lienholder can not repossess a vehicle that is under a mechanic's lien without first paying that lien.
Your lienholder will almost certainly require it.
No. The lienholder is the only entity with a right to repossess.
Only if you have written permission from the lienholder.
As long as there is a lien on the vehicle the lienholder has the right to repossess the property
If the vehicle has a lien, the title shouldn't be lost, the lienholder should have it. Once the vehicle is paid in full, they will mail you the title.
