Tennessee Code Title 36. Domestic Relations § 36-5-907

(a) At any time after the child support obligation has been paid, the person holding title to the property on which the lien is placed may request the department to release the lien. If the department does not release the lien within sixty (60) days of the request, it shall be liable for court costs in any action to remove the lien.

(b) The department may cause the issuance of releases of liens by filing or recording such release of lien with the register of deeds or any other appropriate state or local office as provided under any method authorized pursuant to § 36-5-901 for the filing of notices of liens, or the department may supply copies of such release of liens by the department to any person or entity requesting a release for filing or recording of the release by that person or entity.

(c) The release may be conveyed by any electronic means or by facsimile transmission. If a facsimile transmission is utilized pursuant to this subsection (c), it shall be supplemented by a copy of suitable quality if such facsimile's quality is not adequate for purposes of recording by the register or other appropriate official.
