If you ever watched "It Could Happen To You" with Nicolas Cage and Bridget Fonda, you know that not only good things can happen when people end up fighting over lottery winnings. Be proactive. Create a written agreement between you and your friends or co-workers before the numbers are drawn. For less than the cost of a pizza, protect yourselves a world of future hurt and financial loss with this straightforward agreement. Use it every time you pool lottery tickets.
