Liens are either general or special:
1. A general lien is one which the holder thereof is entitled to enforce as a security for the performance of all the obligations, or all of a particular class of obligations, which exist in the holder's favor against the owner of the property.
2. A special lien is one which the holder thereof can enforce only as a security for the performance of a particular act or obligation and of the obligations that may be incidental thereto.
