There are many steps involved in proceeding with enforcement of a mechanics lien. You have to file a lawsuit to enforce your lien, obtain a judgement enforcing your mechanics lien, then proceed to set up a public sale of the property. At the public sale, you will need to use your lien to acquire the property, although others may bid higher on the property. If you do become the owner of the property through the public sale, then you can consider filing an eviction action against the occupants.
