So here goes.  New client lives with her ex.  Both people file as single.  Both have income through Ebay.  New client had her Ebay account closed several years ago for some issue.  New client sells through her ex's Ebay account (both use same account under ex's name).  How do I remedy this so new client has income and expenses through a SCH C, and ex doesn't have to claim income that's not hers?
