How do I know what procedures and forms to use to file a lien in North Dakota? We are a civil engineering firm that provided services for a company in North Dakota and are now coming up on 90 days from when last services were performed, having yet to be paid by the client. The ND Secretary of State and the Clerk for Williams County both were unhelpful in providing details as to filing procedures, forms, methods, etc. I found the link to forms on the ND Secretary of State web page but am unclear as to which form to properly use. Thanks!
