The builder owed me money on a project and said that I needed to sign an unconditional Lien Waiver so the bank financing the job will release the monies to get me paid since the job was completed.I refused as I did not want to give up my Lien rights and so he drafted up a Promissory Note and signed it stating the amount of Monet owed and the payout structure and of course did not honor that agreement.
