F.S. 713.20 Waiver or release of liens.

(1) The acceptance by the lienor of an unsecured note for all or any part of the amount of his or her demand shall not constitute a waiver of his or her lien therefor unless expressly so agreed in writing, nor shall it in any way affect the period for filing the notice under s. 713.06(2), or the claim of lien under s. 713.08.

(2) A right to claim a lien may not be waived in advance. A lien right may be waived only to the extent of labor, services, or materials furnished. Any waiver of a right to claim a lien that is made in advance is unenforceable.

(3) Any person may at any time waive, release, or satisfy any part of his or her lien under this part, either as to the amount due for labor, services, or materials furnished or for labor, services, or materials furnished through a certain date subject to exceptions specified at the time of release, or as to any part or parcel of the real property.
