How do you put a lien on property for an unpaid debt?

You file a "mechanic's lien" on the property at the courthouse where the property is located. Then, when the property is sold, and abstractor's office does a "search" of the property(looking for liens, etc) the unpaid debt will show and will at that time be addressed for payment prior to closing. All properties must be "free & clear" of all liens before transfer of title can happen. You file a "mechanic's lien" on the property at the courthouse where the property is located.
