Contractual lien - sustany/dvg GitHub Wiki
A contractual lien is a name for a category of�liens�that stem from contracts and do not depend on the common law or statutes for their existence.�A contractual lien is essentially a contract that gives a�security interest�in property to one of the parties involved.�One example would be a�mortgage.
Some insist that a "contractual lien" should not be called a lien at all,�because a "true" lien should arise without the consent of the property owner.� Still, others argue that the concept of contractual liens adds value to discussions about the law.�
See e.g., Pou Chen Corp. v. MTS Products, 183 Cal.App.4th 188, 107 Cal. Rptr. 3d 57 (2010).
