Entered into a Contract with a Client for an ADU (accessory Dwelling unit) in Southern California. Discounted original Contract/Bid from $182.5K to $160K. Started work (without the contracted First Meeting), And essentially completed the unit. The last payment of $2,000.00 is all that remains. Client has requested a TRUE and CORRECT copy of final billing showing all that is left undone and incomplete (under the contract). Am I able to file a Mechanics Lien NOW or a Notice to File...? I have already filed a Notice of Intent to File Lien... and have received several letters asking for the TRUE and CORRECT copy of the final invoice and itemizing What is left Unfinished...
