Law offices fax notices, signed documents and records requests when they need a sender, a time and a receipt. Lawyers in Missouri must protect client confidences under the state’s rules of professional conduct. FaxToFax puts your letterhead on cover pages, keeps a delivery receipt with every fax, and limits who can open faxes with access roles.
