A roofing company subcontracted a solar company to remove and reinstall a solar array from a 1 family home in Arizona. The contractor did not pay the solar company and the solar company doesn't have a written contract with the homeowner. I spoke to the state of arizona registrar of contractors and they stated they would have to file a no pay complaint with the state and they cannot file a lein against the home as they don't have a written contract with the home owner.
