what is the law about issuance of joint checks and how they need to be issued? we have a new software program and vendor set up is not allowing 2 names on a check. I need the law to show the programmers how the check needs to be issued. In the past both names would be on the check with "and" separating the names. All reference materials from workshops in the office were thrown away and i have no resource materials to reference. The paperwork and all legal requirements have been met. Please advise
