I can do it if needed.
In New Hampshire. No state tax on lottery winnings and no state income tax. However, no matter where the tickets are purchased, you must still satisfy the tax requirements for the state in which you reside.
IIRC, NH does allow multiple winners on a ticket (I think each person needs to sign it though, so there are some logistics to consider). NH winners are not anonymous. I believe there may be the option to form a trust which may help with the anonymity and ticket signing issues. A local lawyer would be a must, but I'm not sure how to choose a lottery expert lawyer.
I understand there are always trust issues with people you don't know. I can buy and scan the tickets and send the scan to Kee who can confirm and reimburse me.
Edit: Given the probability of winning big. I do realize the concerns that are related to winning are a little silly, but I'm an optimist.
