I am about to send out a Monthly Notice for March payment through Zlien. According to Zlien resources, Notice of Non-Payment must be provided to the owner within 90 days of last day of the month labor and materials provided. For example, if labor was provided on April 3, then notice is provided 90 days from April 30. Separate notices are required for each month unpaid services or materials are provided. I have two questions before I push the "send" button: - Is "The last date any of the above described Services was furnished was: " the last date of that month of non-payment or today's date if the job is still ongoing? - "The principal amount owed as of the date of this notice is $_____" Is it the amount from that month of non-payment till today, or just the non-payment amount for that specific month?
