It is possible. Motor Vehicles will typically allow the transfer of a motor vehicle with a value not more than $25,000 to be transfered and supplies a form for that purpose. A creditor generally doesn't care too much where the money is coming from -- so long as they are paid in full they will issue the lien release. If you are dealing with stocks, bonds, bank accounts, you will likely need court documents in order for the transfer agent or bank to recognize your ability to deal with individually owned assets.
