A Mechanics Lien Release is a type of release necessary when there has been a mechanics lien placed on a property as a security interest in the title to property for the benefit of vendors or contractors who have supplied materials or labor for improvement to the property. The liens exist for both real property and personal property. When the obligation has been fulfilled, it is necessary to effect a release to disencumber the property as well as to allow a property owner to sell or refinance his or her property.
