I am a subcontractor that finished a public works job. The contractor that hired us is saying they cant pay us because they were bought out by another company. We have contacted everyone we could find that was part of the project. But we just get handed off to someone else or we never hear back from anyone.
Assuming you are a first tier subcontractor (or served a preliminary notice), you might consider serving a stop payment notice or making a payment bond claim. Consult about your particular factual situation with an experienced construction attorney.
