How do I sign on behalf of an LLC that is doing business under a “Doing Business As” (DBA)?

E.x. Real Estate Business LLC with a doing business as registration of REI Investors

Your signature line would read as follows: “John Doe, Manager of X LLC, DBA as X” or “John Doe, Member of X LLC, DBA as X”.
