We have made a deal to accept portion of what is owed us with the General Contractor, which we have in writing. Now the GC is unable to fund the amount owed us until after the 90 days has expired in which to foreclose on our mechanics lien. Per GC the bank made him bond over our lien, and bank has told GC they will fund him 9-1-22 to pay us. Do we need to extend the lien, or what is our next step to protect our position?
