What is an involuntary lien and what are common examples?

An involuntary lien is placed on property without the owner's consent, typically by operation of law or court order. Common examples include property tax liens for unpaid taxes, mechanic's liens for unpaid construction work, judgment liens resulting from court rulings against the owner, and federal or state tax liens from the Internal Revenue Service or state tax authorities. Involuntary liens differ from voluntary liens like mortgages, which the owner willingly agrees to. All involuntary liens must be satisfied or released before clear title can be conveyed to a buyer. ---
