Before you open more than one kind of account I will email Ameritrade's customer service and ask them specifically. Ameritrade has been really good in getting back to you within a day or so. If they give the go ahead, SAVE the email because it may come in handy for the future. I think an individual and joint account will do it. Revocable living Trust accounts and any type of IRAs will NOT work. And always take into account closing/transferring out (and possibly inactivity) fees!
