Georgia is just one of the 12 states in the country that provide statutory lien waiver forms. Failure to use the proper form will result in the waiver being invalid and unenforceable. Ga. Code. §44-14-366 provides the specific language and information that must be included in a lien waiver for the document to be valid.
Keep in mind, that unlike most other states, Georgia lien waivers are conditional for up to 60 days. If payment hasn't been made within that 60-day time period the contractor must either file an Affidavit of Non-Payment, or file their mechanics lien claim. Once that 60-day deadline passes, the waiver becomes unconditional and enforceable; regardless of whether payment has been made.
