Blizzard's customer service is not very friendly on this matter.

I have purchased 5 copies of WoW. The first in my own name, the second in my sons name (even though he was a minor at the time), the third in my wifes name (even though she played less than a month) and 4/5 in my name.

I had no luck, and was treated quite harshly, when I wanted to change the first name on my wifes account. Community property laws be damned, is Blizz's stance. I wish I had asked for a refund, sooner.

The more interesting time was with my sons account. Minors are not allowed to enter the type of agreement that OWNING a wow account entails. This is why sharing an account with 1 minor child is allowed, because the adult must accept the contract, and allow the child to use the account.... Anyways, the account was registered in the name of my minor child. OK, Blizz has a provision to transfer ownership to make the correction to my name. To my knowledge the ONLY circumstance that exists. BUT, since he is now 18, they don't give a damn.

So that is how I bought, paid for, and subscribe 5 accounts, but only play 3 :*(
