A: You went about selling the unit with a debt incorrectly. You needed to get your lean on the boat at the time that you entered into the contract and signed the original documents. The lean has to be registered with the state At the time that the title is issued, not when the buyer defaults on the obligation. As such, your remedy is to Sue the buyer and county court on the unpaid amount.. The suit, if you win,, will give you a judgment which will act as a llien upon the property.. But as of now, you have no direct lien.
