@Setanta,
youve got a year to try to plan wisely and set up foundations and LLC's. (Assuming one can keep his big mouth shut for a year and not give any indications).
Id suggest a family corporation with cash ownership shared as stock but decisons ALL left to the ticket players.Set up a POA , use a good accounting lawfirm. (Most attornies really dont know jack **** about money, many are themselves such "high maintenance idiots" that they , or their partnerships crap out after some really good years)
That way, the money would NOT disappear should one or more of the members die. A "wage based on the annual payments would be distributed s well as any charities or programs youd want to set up to go on in perpetuity.
When people get totally whacked out re: their riches, thats when problems start.
GOOD LUCK. I bought ONE ticket. One or one hundred, you really dont start improving your odds until you start buying like 100000 or more tickets (and even then your in the neighborhood of 1/50000 odds)
