how to release the lien after 90 days expiration.

"And if you allow the lien to expire after 90 days without suing on it becomes invalid, the Owner can file suit against you in Court on a Petition to Release the Property from the Lien, and you may be liable for paying the owners attorney fees and costs if you do not record a release of your expired Mechanics Lien. If your lien has expired, it is thus best to record a lien release voluntarily."
