CACH LLC putting a lein on my property

While going through a long divorce process,I Had a lein put on Property that my husband and I were buying...the debt was from some credit card company..which I didnt owe..the person who owed the debt had the same name as I do..but diffrent socical security number..they served a warrant on this other person,who didnt show up for court..so they put a lein on my property..I have had to file an affidavit saying that I am not the person on the debt..I didnt live at that address,nor was I even living in the same town at tht time...it has been a real hassle going through all of this...question is...How could the legally take a lein on my property??..I am thinking about taking legal action..
