Hello - thank you for this website 1. I served the lien after filing it. The owner's attorney is saying it is invalid because I had to serve before filing. Is that true and if so, what can I do? 2. I never served the 20-day preliminary notice. I was hired by the owner-builder. He is claiming that since he was technically the GC, as a sub I was required to file that notice. Please advice. Thank you!
