Question regarding moving account IP to another location

[Spyren]

Sorry, I don't know if this is the correct area for this question and if I even worded the Title correctly.

Basically whats going on, and my question will follow, is that I got an IP exemption for the wife and I to play in the same house. After both getting up to level 20, she no longer wants to play anymore. She is new to EQ and tried like it for me, but she just couldn't get into it.

My brother went ahead and leveled his character to the mid 40s, so he can't fight with me, but I talked to him about taking over my wife's druid as she's already the same level as me with spells bought and everything.

When I'm on, we can duo, and when I'm not, he can play his main.

He doesn't live with me. Does he need to put in an IP exemption to play a different account at his house even though he won't be playing more than one account at a time?

Sorry if it's a convoluted post and thanks for any help/advise.
