How can a mechanic's lien be removed ?

The party filing  the lien has to file a suit to enforce the lien within 6 months from the time the lien was recorded, or within 60 days of when the building was completed, whichever is later, to enforce the lien. In a nutshell, it will die a natural death if no suit to enforce the lien is filed. The suit to enforce would be filed in the Circuit Court of the same county where the lien was filed.   If you need it released more quickly, the lien can be "bonded off" by getting an insurance company to bond off the claim, at which point the Circuit Court will enter an order removing the lien.
