I am a material supplier on a commercial construction job. The owner is having issues closing on funding the complete the project at approximately 50% complete. I have supplied 99% of my contract and the date we last shipped equipment was 3/12/21. We still owe them 79 components to complete our deliverables. The general contract has promised to pay $10k for June and July so we can reduce our receivable balance from $92,315 to 72,315. Should I file a lien now or wait to see if the general delivers the $10k in June and July before filing?
