Hello. My company is trying to receive payment for a construction job. The GC is requesting two lien releases: 1. Unconditional Waiver and Release Upon Progress Payment for $51,035. They want this prior to sending the check for this amount. 2. Conditional Waiver and Release Upon Final Payment for $2,500.They also want this prior to sending either check. The way I read this says if I sign 1. I must have the 51K check in hand already. If I sign 2. that is saying $2,500 is the final payment; however, I am still owed the 51,035.Can you help me understand this better? Thank you, Karlie
