A lien on property is a type of security interest placed on a piece of property, real or personal, in order to secure a debt or obligation. While the underlying legal theories are different, in a practical sense, a lien is similar to a mortgage, in that the property that is the subject of the lien is taken and sold by the creditor to satisfy the debt of the property owner.
Voluntary Liens are debts that the property owner has agreed to have recorded. Usually this involves a mortgage. It is contrast to the involuntary lien in the sense that the owner of the home is aware of the lien and allows it to take place. This is just one of the types of liens that can be held on a property. There are different scenarios when someone will voluntarily allow a lien to be placed on their property.
