I'm a subcontractor, working on decks on a large condominium. I was provided with an approximate number of sq ft prior to the job and gave the customer a sq footage price based on the number he gave me. I did one side of the condos, sent an invoice and received payment. the square footage is much more than he originally told me prior. I did the other side as requested, and now the customer is not paying anything. Should I file an "amended notice of unpaid balance and right to file lien", or just a "notice of unpaid balance and right to file a lien."
If you already filed the NUB, then you should file an Amended Notice of Unpaid Balance. If you have not filed anything yet, and you still have time to do so, you should file the Notice of Unpaid Balance.
"Subcontractor" implies that you do not have a direct contractual relationship with the property owner. Was your proposal signed by the general contractor? Is there another written subcontract form that you signed by the GC?
